[0001] [0001] This order refers to the communications field and, more specifically, a service discovery method, a registration center and a device. FUNDAMENTALS
[0002] [0002] Service registration and discovery is a directory service that facilitates service definition, service selection and service execution policy. As a service provider, a service provider registers service information for the service provider with a service registration center. The service registration center primarily provides central storage for all service registration information and is responsible for sending a service registration information update notification to a service consumer in real time. The service consumer obtains the required service registration information from the service registration center, and invokes a service.
[0003] [0003] In a network service system, a network provider publishes a network service provided at a registration center, a customer discovers a necessary network service at the registration center and the customer obtains a network service endpoint . The performance of the service (for example, a sustained protocol and a transmission mode) in a conventional network system is relatively simple. The customer can select a suitable service based on a service identity (Identity, ID). A fixed format is usually used when invoking network service. As the network system is updated, that is, as services tend to be diversified, the customer is unable to find a suitable service through the use of a conventional solution. This deteriorates the quality of the service. SUMMARY

[0077] [0077] The technical solutions of this application are described below with reference to the attached drawings.
[0078] [0078] FIG. 1 is an architectural diagram of service discovery and registration. As shown in FIG. 1, service discovery and registration is a directory service that facilitates a service definition, service selection and service execution policy. As a service provider, a service provider registers the service provider's service information with a service registration center. The service registration center primarily provides central storage for all service registration information and is responsible for sending a service registration information update notification to a service consumer in real time. The service consumer obtains the required service registration information from the service registration center, and invokes a service.
[0079] [0079] Several elements in a service discovery and registration system are specifically defined as follows.
[0080] [0080] A service (Service) is a loosely coupled, coarse-grained component that can independently implement a logical function and is available for invocation by a service consumer (an application / network element or other component).
[0081] [0081] An end point (End point) is a discovery address notified to a service consumer by a service instance and the service instance uses the address to expose information.
[0082] [0082] Contracts are contracts to which a service and a server invoker adhere, such as a version of the application programming interface (API), a uniform resource identifier directory (Uniform Resource Identifier, URI ), a number of parameters and a message format.
[0083] [0083] A service registry is used when a plurality of service instances are the same or a service instance needs to be generated dynamically. The service instance can provide an endpoint and a service instance contract to the registration center, so that a service invoker finds out if he normally uses the service.
[0084] [0084] FIG. 2 is a schematic flowchart for registering and discovering a network service (Web Service).
[0085] [0085] 201. A network provider publishes a network service provided at a registration center. The network service published by the network provider in the registration center can be information specifically characteristic of the network service, such as at least one of a service identity (Identity, ID), a service name, a version number, a Provider ID, an endpoint, an interface table, or a supplier.
[0086] [0086] 202. A customer discovers a necessary network service at the registration center and, specifically, the registration center searches for the characteristic information of the network service to find the appropriate network service.
[0087] [0087] 203. The client obtains an end point from the network service.
[0088] [0088] FIG. 3 shows a scenario in which service registration and discovery are applied to a mobile edge computing system (Mobile Edge Computing, MEC). As shown in FIG. 3, the MEC system mainly includes a mobile edge orchestrator (Mobile Edge Orchestrator, MEO) and a mobile edge host (Mobile Edge Host). MEO has a main management function in the MEC system. The mobile edge host mainly includes a mobile edge platform (Mobile Edge Platform), a virtualization infrastructure (Virtualization infrastructure) and a mobile edge application (Mobile Edge Application, ME app).
[0089] [0089] The mobile edge platform is a set of basic functions, capable of running the mobile edge application on a specific virtualization infrastructure and makes the mobile edge application capable of providing and using a mobile edge service. The mobile edge application is an application instantiated in the virtualization infrastructure of the mobile edge host based on a MEO configuration or request. The mobile edge application includes a service provider (Service Provider) and a service consumer (Service Consumer). In addition, a Service Registry is located on the mobile edge platform and a service instance can provide an endpoint and a service instance contract for the registration center, so that a service invoker finds out normally uses the service instance.

[0091] [0091] FIG. 4 shows a scenario in which service registration and discovery are applied to a system 6 working group of services and systems aspects (Services and Systems Aspects Work Group, SA). As shown in FIG. 4, the SA6 system includes a mission critical service (Mission Critical Service, MC Service), a service access server, a common main service (common service core, CSC), an external application and an operations support system ( Operation Support System, OSS). The MC service controls the ability of a service to be exposed to the external application through the use of the service access server. The mission-critical service consults and discovers a service on the service access server and then implements service communication through a reused interface.
[0092] [0092] FIG. 5 is a schematic diagram of a scenario in which service registration and discovery are applied to an SA2. As shown in FIG. 5, the SA2 system includes a network function repository function (Network Function Repository Function, NRF), a first network function instance (Network Function, NF) (NF Instance, NFI), a second instance of network function and management and orchestration (Management and Orchestration, MANO). The NRF maintains information about an NFI deployed during the deployment, update and deletion of the network role instance. The NRF supports a service discovery function, receives a network function discovery request from the NFI and provides information found about the NFI to the NFI.
[0093] [0093] In summary, network service registration and discovery can be applied to the mobile edge computing system (Mobile Edge Computing, MEC), the SA6 system and the SA2 system. The MEC system is used as an example. In a conventional MEC system, a service consumer can use only one RESTful API to invoke a service from a service provider, so the network provider and discoverer need not consider a transmission interface. In other words, in the conventional solution, the network provider and the discoverer use the fixed interface.
[0094] [0094] In the European Telecommunications Standards Institute (ETSI) that meets MEC # 8B, an MEC system not only supports a RESTful API, but also supports a layer service interface transport used to support transmission with low latency and a large volume of data, for example, a Message Queuing Telemetry Transport Protocol (MQTT), an Advanced Message Queuing Protocol (AMQP) and a Private Remote Procedure Call Protocol (RPC). In contrast, in conventional technology, an adequate service cannot be found based on a requirement for an interface and, consequently, the quality of the service is reduced.
[0095] [0095] FIG. 6 is a schematic flowchart of a service discovery method, according to an embodiment of this request. As shown in FIG. 6, the method is applied to a network service system. The network service system includes a registration center, a first device and a second device. The method includes the following steps:
[0096] [0096] 601. The registration center receives a service discovery request sent by the first device, where the service discovery request carries target parameter information for a service required by the first device, the target parameter information includes at least one between information about a first transmission mode, information about an invocation mode, information about a transmission protocol and information about a second transmission mode, information about the first transmission mode is an in-band identifier or an out-of-band identifier band, the in-band identifier is used to indicate a transmission mode in which invocation information is added to the data for transmission, the out-of-band identifier is used to indicate a transmission mode in which the data and invocation information are transmitted separately, the invocation mode is a -request-a-response or a -request -multiple-responses, the transmission protocol is any one of a Representational State Transfer Application Programming Interface protocol, an Advanced Message Queue Interface Protocol, a Message Queuing Telemetry Transport Protocol and a Protocol Remote Procedure Call and the second transmission mode performs the transmission directly or through the use of an intermediate node.
[0097] [0097] 602. The registration center determines, based on a service parameter database, a target service corresponding to the target parameter information, where the service parameter database is used to store service parameter information different services from the second device.
[0098] [0098] 603. The registration center sends a service response message to the first device, where the service response message includes the target service description information.
[0099] [0099] 604. The first device sends the invocation information to the second device, where the invocation information is used to invoke the target service.
[0100] [0100] The first device sends the service discovery request to the registration center, where the service discovery request is used to request the service, included in the second device, corresponding to the target parameter information and the service discovery request. carries the target parameter information. The service parameter database stores the parameter information for the different services on the second device and all services are matched one by one for parameter information. The description information for each service corresponding to the parameter information can be specifically a service ID. After receiving the service discovery request, the registration center searches the service parameter database for the target service that satisfies the target parameter information and sends the service response message including the target service description information to the first device, so that the first device can send the invocation information based on the target service description information, to invoke the target service of the second device. In other words, a necessary service can be selected with more precision for the first device in this modality of this order, thereby improving the quality of the service.
[0101] [0101] The parameter information targeting the service required by the first device can be parameter information corresponding to the service required by the first device. For example, the target parameter information can be information about the first mode of transmission, information about the invocation mode, information about the transmission protocol, information about the second mode of transmission or the like that is used when the first device sends the invocation information to the second device after selecting the target service and receiving a response message sent by the second device based on the invocation information.
[0102] [0102] It should be noted that the service discovery request sent by the first device to the registration center can additionally carry at least one of a service ID, a service name, a version number, a provider ID, a point end, an interface table or a supplier.
[0103] [0103] It should be understood that a correspondence between a service and parameter information can be represented using a mapping relationship, in another way or similar. This is not limited in this order.
[0104] [0104] It should also be understood that in the service parameter database, each service corresponds to a part of the parameter information and the parameter information also includes at least one among the information about the first transmission mode, the information about the invocation mode, information about the transmission protocol and information about the second mode of transmission.
[0105] [0105] It should also be understood that the first device can be a hardware device or a software application and the second device can be a hardware device or a software application. In addition, the first device can be the same as the second device.
[0106] [0106] To summarize, according to the service discovery method in this modality of this order, the registry center receives the service discovery request sent by the first device, where the service discovery request carries the target parameter information of the service required by the first device and the target parameter information includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission; determines, based on the service parameter database, the target service corresponding to the target parameter information; and sends the service response message including the target service description information to the first device. In this way, among the diversified services, a suitable service can be found for the first device based on the service support parameter information. Therefore, the quality of service can be improved and the processing efficiency of the system can be improved. In addition, according to the service discovery method in this modality of this order, the management and extension of the network system can be facilitated.
[0107] [0107] Optionally, the registration center can receive a registration request, where the registration request includes the parameter information of a first service of the second device; and the registration center stores the parameter information for the first service in the service parameter database. The first service can be any of the services supported by the second device. For specificity, the registration center can store parameter information from a plurality of different services in the parameter database; and after receiving the service discovery request, consult the parameter database for parameter information that satisfies a requirement and determine a service corresponding to the parameter information that satisfies the requirement.
[0108] [0108] It should be noted that when the second device sends the registration request to the registration center, the parameter information included in the registration request is the same as the parameter information included in the service discovery request and also includes at least one of the information about the first mode of transmission, information about the mode of invocation, information about the transmission protocol and information about the second mode of transmission, information about the first mode of transmission is the identifier within band or the out-of-band identifier, the in-band identifier is used to indicate the transmission mode in which the invocation information is added to the data for transmission, the out-of-band identifier is used to indicate the transmission mode in which the invocation data and information are transmitted separately, the invocation mode is a -request-a-response or a -request-multiple-responses, the transmission protocol is any of the Representational State Transfer Application Programming Interface Protocol, the Advanced Message Queue Interface Protocol, the Message Queuing Telemetry Transport Protocol and Remote Procedure Call Protocol and the second transmission mode performs the transmission directly or through the use of the intermediate node.
[0109] [0109] It should be understood that the registration request may additionally carry at least one of a service ID, a service name, a version number, a provider ID, an endpoint, an interface table or a supplier.
[0110] [0110] Optionally, if the target parameter information includes information about the first mode of transmission, the information about the first mode of transmission can be the out-of-band identifier or the in-band identifier. The in-band identifier is used to indicate the mode of transmission in which the invocation information is added to the data for transmission and the out-of-band identifier is used to indicate the mode of transmission in which the data and invocation information is transmitted. separately. If the information about the first transmission mode included in the target parameter information is the identifier within the band, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes the identifier within band, as the target service. Likewise, if the information about the first transmission mode included in the target parameter information is the out-of-band identifier,
[0111] [0111] Specifically, if the information about the first transmission mode included in the target parameter information is the in-band identifier, the invocation information to be sent by the first device to the second device can be added to the data for transmission, for example example, by using a Transmission Control Protocol (TCP) option (option). As shown in FIG. 7, if the information about the first transmission mode included in the target parameter information is the out-of-band identifier, the invocation information and data that is sent by the first device to the second device can be transmitted separately. The registration center selects, for the first device, the second device that satisfies the requirement, so that the first device can obtain high quality service.
[0112] [0112] Optionally, as shown in FIG. 8, the target parameter information may include information about the invocation mode, where the invocation mode is one-request-one-response or one-request-multiple-response. A-request-a-response can be a service that, after the first device sends invocation information to the second device once, the second device responds to a request for invocation information once. In this way, services that need different contracts can be handled separately, thereby increasing processing efficiency. One-request-multiple-responses can be a service that, after the first device sends invocation information to the second device once, the second device can respond to a request for invocation information several times, that is, the validity of a subscription lasts for a long time. This avoids sending invocation information multiple times between devices that need the same service, thereby reducing the power consumption of the first device.
[0113] [0113] If the invocation mode is a-request-a-response, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes the information about a-request-a -response, as the target service. Likewise, if the invocation mode is one-request-multiple-responses, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes the information about a-request- multiple responses, such as the target service.
[0114] [0114] Optionally, the target parameter information includes information about the transmission protocol, where the transmission protocol is any of the RESTful API protocol, the AMQP, the MQTT protocol and the RPC protocol. FIG. 9 is a schematic diagram of a RESTful API protocol and an AMQP protocol. If the transmission protocol is the AMQP protocol, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes information about the AMQP protocol, such as the target service. Likewise, if the transmission protocol is any one of the RESTful API protocol, the MQTT protocol and the RPC protocol, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes information about the corresponding interface protocol, such as the target service.
[0115] [0115] Optionally, the target parameter information includes information about the second transmission mode. As shown in FIG. 10, the second transmission mode performs the transmission directly or through the use of an intermediate node. If the second transmission mode is transmitting directly, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes the information indicating that the transmission is carried out directly, such as the service target. Likewise, if the second transmission mode is carrying out the transmission using the intermediate node, the registration center will determine a service corresponding to the parameter information that is in the service parameter database and that includes the information indicating that the transmission is performed through the use of the intermediate node, as the target service. In this way, the second device can allow a first device corresponding to a trusted application or an application in the same domain to directly access the service, but it allows a first device corresponding to an untrusted application or an application in another domain to access the service only after authentication or format conversion of the message is performed by an intermediary entity. This improves the security performance of the second device.
[0116] [0116] Optionally, the target parameter information additionally includes an intermediate node location and as shown in FIG. 11, the intermediate node is located on a third party device, a registration center or a second device. The determination, by the registration center when the second transmission mode performs the transmission through the use of the intermediate node, of a service corresponding to the parameter information that is in the service parameter database and that includes the information indicating that the transmission is carried out through the use of the intermediate node, as the target service can be specifically: to determine, by the registration center when the second mode of transmission performs the transmission through the use of the intermediate node and the intermediate node is located in the device of third parties, a service corresponding to the parameter information that is in the service parameter database and that includes the information indicating that the transmission is performed using the intermediate node and that the intermediate node is located on the third party device, as the target service.
[0117] [0117] It should be noted that when the target parameter information includes at least two of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission. transmission, the registration center can determine any of the services corresponding to all the information that is in the service parameter database and that is included in the target parameter information, such as the target service; or the registration center can determine a service with a higher proportion among the services corresponding to all information, such as the target service. The system can preset a rule for the registration center to determine a target service. This is not limited in this order.
[0118] [0118] Optionally, the network service system is an MEC mobile edge computing system; the MEC system includes a moving edge orchestrator and a moving edge host; the moving edge host includes a moving edge platform, a first moving edge application and a second moving edge application; the mobile edge platform corresponds to the registration center, the first mobile edge application corresponds to the first device and the second mobile edge application corresponds to the second device; and the mobile edge orchestrator is configured to manage the first mobile edge application and the second mobile edge application.
[0119] [0119] Specifically, the first mobile edge application can select different interface protocols such as the MQTT protocol, AMQP and the RPC Private Remote Procedure Call Protocol. In other words, a suitable service is found based on a requirement for an interface protocol, thereby improving the quality of the service.
[0120] [0120] Optionally, the network service system is an SA6 system. The SA6 system includes a service registration server, a mission-critical service and an external application; and the service registration server corresponds to the registration center, the external application corresponds to the first device and the mission critical service corresponds to the second device.
[0121] [0121] In SA6, the external application located in a trusted domain other than that of the mission critical service uses a service access server. In this case, a service is used to implement an application for users in different trusted domains / deployment domains. A trusted application or an application in the same domain can directly access the service, while an untrusted application or an application in another domain can access the service only after authentication or format conversion of the message is performed by an intermediary entity.
[0122] [0122] Optionally, the network service system is an SA2 system. The SA2 system includes a network function repository function, a first network function instance and a second network function instance; and the network function repository function corresponds to the registration center, the first network function instance corresponds to the first device and the second network function instance corresponds to the second device.
[0123] [0123] In SA2, an attribute of a network function (Network Function, NF) is the same as an attribute of a service and can be a one-to-one mapping relationship between the network function and the service. The NF can be directed to third parties and a network element on a public terrestrial mobile network (Visited Public Land Mobile Network, VPLMN) or it can be directed to a network element on a residential public terrestrial mobile network (Home Public Land Mobile Network, HPLMN) and the way to obtain interfaces and messages may be different. For example, in an evolved packet system (Evolved Packet System, EPS), a message getting the procedure for an S5 interface between a serving gateway (Serving Gateway, S-GW) and an H packet data gateway (Packet Data Gateway, PGW) are different from a message that obtains the procedure for an S8 interface between an S-GW and a V-PGW. A network exposure function (Network Exposure Function, NEF) is targeted at an internal network element and third parties in the future and the ways of obtaining interfaces and messages can also be different. In this way, a second suitable network function instance can be selected for the first network function instance more accurately based on the parameter information, thereby improving the quality of service.
[0124] [0124] To summarize, according to the service discovery method in this modality of this order, the registry center receives the service discovery request sent by the first device, where the service discovery request carries the target parameter information of the service required by the first device and the target parameter information includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission; determines, based on the service parameter database, the target service corresponding to the target parameter information; and sends the service response message including the target service description information to the first device. In this way, among the diversified services, a suitable service can be found for the first device based on the service support parameter information. Therefore, the quality of service can be improved and the processing efficiency of the system can be improved.
[0125] [0125] FIG. 12 is a schematic diagram of an interaction procedure for a service discovery method, according to one embodiment of this request. Several of the same terms in this modality have the same meanings as those in the previous modalities.
[0126] [0126] The method can be applied to the MEC system shown in FIG.
[0127] [0127] An application developer can implement two applications, according to a contract (for example, a development manual or the 3rd Generation Partnership Project standard, the 3rd Generation Partnership Project, 3GPP): implement an interface on contract and invoke a related interface function, according to the contract. Before implementing this modality of this order, the MEC system implements both applications on devices in the MEC system through the use of a MEO.
[0128] [0128] 1201. MEO implements a mission critical service application installation package (App package), including an application resource requirement, an application file, a required service description and the like.
[0129] [0129] 1202. After receiving an application installation request, MEO controls the application installation package to generate an application instance from the provider, that is, a service that can be provided, in the second mobile edge application.
[0130] [0130] 1203. The second mobile edge application sends a registration request to the mobile edge platform, where the registration request includes the service support parameter information.
[0131] [0131] Specifically, the parameter information includes at least one of the information about a first mode of transmission, information about an invocation mode, information about a transmission protocol and information about a second mode of transmission, information about the first transmission mode is an in-band identifier or an out-of-band identifier, the in-band identifier is used to indicate a transmission mode in which invocation information is added to the data for transmission, the out-of-band identifier is used to indicate a transmission mode in which the data and invocation information are transmitted separately, the invocation mode is a -request-a-response or a -request-multiple-responses, the transmission protocol is any one of an Interface protocol Representational State Transfer Application Programming, an Advanced Message Queue Interface Protocol, a Pro Message Queuing Telemetry Transport protocol and a Remote Procedure Call Protocol and the second mode of transmission performs the transmission directly or through the use of an intermediate node.
[0132] [0132] 1204. The mobile edge platform stores the service and the service parameter information in a service parameter database. Specifically, the parameter information includes at least one of the information about a first mode of transmission, information about an invocation mode, information about a transmission protocol and information about a second mode of transmission.
[0133] [0133] Because the registration request can be sent to the mobile edge platform for different services, the service parameter database stores a plurality of different services and parameter information corresponding to the services.
[0134] [0134] 1205. After receiving a consumer application instantiation request, MEO can control the application installation package to generate a consumer application instance, that is, a required service, in the first mobile edge application.
[0135] [0135] It should be understood that if the mobile edge platform stored the parameter information for the different services, step 1205 can be performed directly and steps 1201 to 1204 do not need to be performed.
[0136] [0136] 1206. The first mobile edge application sends a service discovery request to the mobile edge platform, where the service discovery request includes the required service parameter information and the parameter information can be represented as information target parameter. Specifically, the target parameter information also includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission.
[0137] [0137] 1207. The mobile edge platform determines, based on the service parameter information stored in the service parameter database, a target service that satisfies the target parameter information.
[0138] [0138] 1208. The mobile edge platform sends a service response message to the first mobile edge application, where the service response message includes the target service description information.
[0139] [0139] 1209. The first mobile edge application triggers an invocation procedure based on the service response message.
[0140] [0140] 1210. The first mobile edge application performs the invocation procedure based on the description of the target service in the service response message.
[0141] [0141] Specifically, invocation information can be sent to the second mobile edge application, to invoke the target service in the second mobile edge application. The invocation procedure includes, for example, the preparation of a resource to be requested, the storage of a context, the query for the context and content return or an invocation result.
[0142] [0142] To summarize, according to the service discovery method in this modality of this order, the mobile edge platform receives the service discovery request sent by the first mobile edge application, where the service discovery request carries the information of the service target parameter required by the first mobile edge application and the target parameter information includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission; determines, based on the service parameter database, the target service corresponding to the target parameter information; and sends the service response message including the target service description information to the first mobile edge application. In this way, among the diversified services, a suitable service can be found for the first mobile edge application based on the application service that supports the parameter information. Especially among application services that support a plurality of interface protocols or different invocation modes, the first mobile edge application can select a satisfactory interface protocol and the invocation mode to transmit the invocation information, thereby improving transmission efficiency.
[0143] [0143] FIG. 13 is a schematic diagram of an interaction procedure for a service discovery method, according to another modality of this order. Several of the same terms in this modality have the same meanings as those in the previous modalities.
[0144] [0144] The method can be applied to the SA6 system shown in FIG. 4. A registration center can correspond to a service access server, a first device can correspond to an external application used to request a service and a second device can correspond to a mission-critical service used to provide a service . In other words, the external application is a "service consumer" and the mission-critical service is a "service provider".
[0145] [0145] An application developer can implement two applications, according to a contract (for example, a development manual or the 3GPP standard): implement an interface in the contract and invoke a related interface function, according to the contract. Before implementing this modality of this request, the SA6 system implements both applications on the devices in the SA6 system through the use of an OSS.
[0146] [0146] 1301. The OSS implements a mission critical service installation package (MC package).
[0147] [0147] 1302. After receiving an application instantiation request, OSS controls the application installation package to generate a provider application instance, that is, a service that can be provided, in the mission critical service.
[0148] [0148] 1303. The mission-critical service sends a registration request to the service access server, where the registration request includes the service support parameter information.
[0149] [0149] Specifically, the parameter information includes at least one of the information about a first mode of transmission, information about an invocation mode, information about a transmission protocol and information about a second mode of transmission, information about the first transmission mode is an in-band identifier or an out-of-band identifier, the in-band identifier is used to indicate a transmission mode in which invocation information is added to the data for transmission, the out-of-band identifier is used to indicate a transmission mode in which data and invocation information are transmitted separately, the invocation mode is a -request-a-response or a -request-multiple-responses, the transmission protocol is any one of an Interface Protocol Representational State Transfer Application Programming, an Advanced Message Queue Interface Protocol, a Pro Message Queuing Telemetry Transport protocol and a Remote Procedure Call Protocol and the second mode of transmission performs the transmission directly or through the use of an intermediate node.
[0150] [0150] 1304. The service access server stores the service and the service parameter information in a service parameter database. Specifically, the parameter information includes at least one of the information about a first mode of transmission, information about an invocation mode, information about a transmission protocol and information about a second mode of transmission.
[0151] [0151] Because the registration request can be sent to the service access server for different services, the service parameter database stores a plurality of different services and parameter information corresponding to the services.
[0152] [0152] 1305. After receiving an instantiation request from the consumer application, the OSS can control the application installation package to generate an instance of the consumer application, that is, a required service, in the external application.
[0153] [0153] It should be understood that if the service access server has stored parameter information for the different services, step 1305 can be performed directly and steps 1301 to 1304 need not be performed.
[0154] [0154] 1306. The external application sends a service discovery request to the service access server, where the service discovery request includes the required service parameter information and the parameter information can be represented as parameter information target. Specifically, the target parameter information also includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission.
[0155] [0155] 1307. The service access server determines, based on the service parameter information stored in the service parameter database, a target service that satisfies the target parameter information.
[0156] [0156] 1308. The service access server sends a service response message to the external application, where the service response message includes the target service description information.
[0157] [0157] 1309. The external application triggers an invocation procedure based on the service response message.
[0158] [0158] 1310. The external application performs the invocation procedure based on the description of the target service in the service response message.
[0159] [0159] Specifically, invocation information can be sent to the mission critical service, to invoke the target service in the mission critical service. The invocation procedure includes, for example, preparing a resource to be requested, storing a context, consulting the context and returning content or an invocation result.
[0160] [0160] To summarize, according to the service discovery method in this modality of this request, the service access server receives the service discovery request sent by the external application, where the service discovery request carries the parameter information target of the service required by the external application and the target parameter information includes at least one of the information about the first mode of transmission, information about the invocation mode, information about the transmission protocol and information about the second mode of transmission streaming; determines, based on the service parameter database, the target service corresponding to the target parameter information; and sends the service response message including the target service description information to the external application. In this way, among the diversified services, a suitable service can be found for the external application based on the service support parameter information. In particular, a trusted application or an application in the same domain can directly access the service, while an untrusted application or an application in another domain can access the service only after authentication, format conversion or the like, are performed by an intermediary entity . This improves the security performance of the network system.
[0161] [0161] FIG. 14 is a schematic diagram of a service discovery method interaction procedure, according to one embodiment of this request. Several of the same terms in this modality have the same meanings as those in the previous modalities.
[0162] [0162] The method can be applied to the SA2 system shown in FIG.
[0163] [0163] An application developer can implement two applications, according to a contract (for example, a development manual or the 3GPP standard): implement an interface in the contract and invoke a related interface function, according to the contract. Before implementing this modality of this request, the SA2 system implements two applications on the devices in the SA2 system through the use of MANO.
[0164] [0164] 1401. MANO implements a network function installation package (Network Function Package, NF package).
