    DK 2012 00120 U8
    The invention relates to the field of mobile communications, and in particular to a network designed to implement user registration based on Diameter Network Protocol.
    With the emergence of new technologies, 3GPP (3 <rd> Generation Partnership Project) must consider how it can maintain its technically leading edge in the field of mobile communications in the next ten years and provide satisfactory support to increasing demands from operators and subscribers through continuous development and improvement from wireless interface to core network in the system architecture development of the future mobile communications area. The development program of packet-switched domain core network facing all IPs (System Architecture Evolution, SAE), now called EPS (Evolved Packet System), has just emerged on this background. The purpose of SAE is to "establish a 3 GPP system framework structure with portability characterized by high data rate, low delay, data packet assembly and support of multiple wireless access techniques".
    An SAE network has features that include support for end-to-end QoS (Quality of Service) assurance, all-round packet assembly, support for multi-access technology, enhancement of real-time service support, flattening of network hierarchy, etc. The SAE network achieves further separation of control surface data from user interface data and a new MME (Mobility Management Entity network element) with elements such as roaming support, authentication and bearing management, as a network function unit for transporting user data on the control surface. The S6a interface between MME and HSS (Home Subscriber Server), as shown in FIG.1, provides user data downloads, authentication data, etc.
    After first accessing a network via various access networks, it is required before using network resources that a user registers the location information of the user access point to its HSS and that the HSS checks the validity of the user. For a valid user, the HSS determines, in accordance with user subscription data, whether the user has permission to use the network resources, and if the user has permission 2 DK 2012 00120 U8 to use the network resources, related user data information is downloaded (eg user subscription data, etc. ) to the visited network where the user is located; for an invalid user, the HSS rejects the user from using the network resources. Such a process, called a user registration, mainly involves registration of user location information and user data download process (if the user is initially registered on the network or the user data stored on the access network is not reliable, or the like).
    FIG. 2 is a flowchart of a user registering on the user's Home Location Register (CPR) through a SGSN network node (Service GPRS Supporting Node, which is a network element responsible for mobility management on the core network side) in an accessive manner such as UTRAN (Universal Terrestrial Radio Access Network) or UMTS (Universal Mobile Telecommunication System), etc. in a packet-switched domain. The GR interface between an SGSN and a CPR is based on MAP network protocol and the flow of user registration includes the following steps:
    Step 201, a user creates a network connection request through an access network;
    Step 202, an SGSN receives the user's network connection request and detects that the user is initially connected to the network and that the MME has no user data information, the SGSN configures a user subscription data download indicator and creates an Update Location Request message (ULR HLR message) based on MAP network protocol, where the request message carries the user subscription data download indicator;
    Step 203, the user's CPR checks the user, and triggers the download of user data according to the user subscription data download indicator; if it is not necessary to download user data, then step 204 and step 205 are skipped and an Update Location Ack message is returned directly; if it is necessary to download user data, then steps 204 and step 205 for downloading user data are run, in which the process of downloading user data can be run several times; 3 DK 2012 00120 U8
    Step 204, the CPR sends a data insertion request message to the SGSN, the message including information such as user subscription data;
    Step 205, the SGSN checks user data and returns a data insert Ises-ack message to the CPR, where the ack message includes subscription data that is not supported by the SGSN and the like;
    Step 206, after receiving the data insertion acknowledgment message, the CPR performs an additional action in accordance with the result of the data check, for example, restoration of service data and the like; if user data is successfully downloaded, the CPR stores the user registration location information and returns an Update Location Ack message of success to the SGSN.
    The above steps complete the user registration process based on MAP network protocol between SGSN and CPR, where step 202 and step 206 complete registration of user location information, step 204 and step 205 complete download of user data and verification / negotiation, thus completing registration of user location information and download of user data and verification / negotiation in one session.
    FIG. 3 is a flowchart of a user registering with an HSS in an IP multimedia domain. FIG. 3 only describes the flow of user re-registration to briefly describe user registration, where l-CSCF (Interrogation Call Session Control Function) and S-CSCF (Serving Call Session Control Function) are two network elements used for session control in a IP multimedia domain, and are respectively an access point in the core network and a service control point in a user session. The interface between l-CSCF and S-CSCF is based on SIP Initial Protocol (SIP) network protocol, and the Cx interface between l-CSCF, S-CSCF and HSS is based on Diameter Network Protocol. The flow includes the following steps:
    Step 301, an l-CSCF receives a SIP registration request from a visited network where the user's HSS is known upon request, and then sends a user authentication request to the HSS;
    Step 302, upon receipt of the user authentication request from the 4 DK 2012 00120 U8 l-CSCF, the HSS directly returns the name of an S-CSCF if, upon request, it knows that the user has registered with the S-CSCF;
    Step 303, the HSS returns a user authentication ack message to the l-CSCF, where the ack message includes the name of the S-CSCF;
    Step 304, the 1-CSCF forwards the SIP registration request to the S-CSCF;
    Step 305, the S-CSCF processes the SIP registration request, sends a server allocation request to the HSS, and registers the user's location information and requests the download of user data;
    Step 306, upon receipt of the server allocation request, the HSS checks whether the S-CSCF name matches the stored S-CSCF name, and if so, allows the user to register and returns a server allocation ack message on success, where the ack message includes the user data requested for download;
    Step 307, the S-CSCF returns 2000K to the l-CSCF.
    With the above steps, the user completes the registration process in an IP multimedia domain, which involves several network elements, where registration of location information and downloading of user data involved in user registration is completed in steps 305 and 306. With regard to implementing a user registration for a CPR through an SGSN in a packet-switched domain the difference is that there is no negotiation process on the control result of user data between S-CSCF and HSS.
    When the user intends to access a network in an E-UTRAN (Evolved-UTRAN) access method in a packet-switched domain, the user must implement user registration on the user's HSS via the MME network node. The function of an MME is similar to that of an SGSN, and the MME is a network node in a control interface, which is mainly responsible for the mobility management of a user in an EPS network. At present, it is certain that the S6a interface between an MME and an HSS will use Diameter protocol, and user registration processes vary based on different data storage and data management of user data in different network domains. Because the function of an MME is similar to the function of a SGSN and the incorporation of an MME network element is mainly based on the development of a packet-switched domain, the functions completed by user registration between MME and HSS are similar to those completed in user registration. between SGSN and CPR, i.e. that not only registration of user location information must be completed, but also download of user data and verification / negotiation of user data.
    However, implementing a user application process based on Mobile Application Part Network Protocol (MAP) protocol protocol cannot be totally mapped to a Diameter network protocol, mainly because the application session state machine in a Diameter network protocol and in a MAP network protocol are different from each other. The IETF (Internet Engineering Task Force) specifies that a Diameter protocol must support a Diameter base protocol, in other words, an S6a interface protocol must also match the state machine in the client and the server required for a user session defined in a Diameter basic protocol.
    Diameter user session indicates that a server may or may not be in session maintenance mode. Whether or not it maintains session mode, the working mechanism of a Diameter user session mode machine differs from that of a MAP user session mode machine. A MAP user session state machine allows multiple interactive requests to be initiated between equivalent ends after a session is established, i.e., upon receipt of a session request from an equivalent end, a local end during establishment of a session has permission to resume sending a session request to the equivalent end, and upon receiving a session response from the equivalent end, may return a session response to the equivalent end. Except for a session end request, a Diameter user session state machine does not allow a client machine to receive requests from a server after the session is activated, and only allows it to process acknowledgment messages from the server.
    With the help of a session state machine provided by a MAP protocol, the home domain network can implement negotiation of capability information with the visited domain network when a user registers in a visited domain network. For example, when the user home domain network receives a user registration message, it inserts user data into the visited domain network, and if user data insertion failed, it returns a data insertion error message, where the user's home domain network prohibits the user from registering and returns a reply message , in which the user roams. If the Diameter protocol is used, the user's home domain network HSS can only return a registration response message when it receives a user registration request message, and user registration is considered successful when a successful registration message is returned.
    Registration of an SGSN to a CPR based on MAP protocol includes registration of location information and download of user data as well as a process for data verification / negotiation, but this process requires several signaling interactions. IMS registration based on Diameter protocol and registration between S-CSCF and HSS only needs one signaling interaction to implement registration of location information and download of user data, but lacks the process for data verification / negotiation, as the HSS believes that the properties of the l- CSCF selected S-CSCF supports all user data, so the process for data verification / negotiation is not needed.
    To summarize, the problems with the prior art are as follows: the user registration process implemented on the basis of MAP network protocol in a packet-switched domain can not be used to implement user registration between MMES and HSS based on Diameter network protocol in development of a packet-switched domain, and the existing flow in user registration implemented on the basis of Diameter network protocol can also not be used for user registration between MME and HSS.
    The technical problem to be solved by the generation is to provide a network arranged for implementing user registration, in order to solve the problem in the prior art that the existing flow in user registration cannot solve the problem of user registration between a network node and HSS in a packet-switched domain, thereby implementing user-7 DK 2012 00120 U8 registration based on Diameter network protocol.
    To solve the above problem, the invention provides a network arranged for implementing user registration, and the network is based on Diameter network protocol, and comprises that; a request node, upon receipt of a network connection request from a user, sends an Update Location Request message to the home subscriber server (HHS) belonging to the user, where the request includes information indicating whether it is necessary to download user subscription data, and also , when download is required, includes additional information indicating the properties of the request node; and the user's HHS returns an Update Location Ack message to the request node when it receives the Update Location Re-quest message if the control of the user is approved; if the Update Location Request message indicates that it is necessary to download user subscription data, the HSS determines the user subscription data supported by the request node according to the information indicating the properties of the request node and includes user subscription data in the Update Location Ack message to be returned to the request node.
    In addition, the above network may also include the following features: the information indicating the properties of the request node refers to: whether the Update Location Request message includes information about the properties of the request node; when the request node does not support all user subscription data, the Update Location Request message sent to the HSS by the request node contains information about the properties of the request node; when the request node supports all user subscription data, the Update Location Request message sent to the HSS by the request node does not contain information about the properties of the request node.
    Furthermore, the above network may also include the following features; 8 DK 2012 00120 U8 the information about the properties of the request node refers to a collection of services supported by the node, including Operator Data Barring data (ODB data), and regional subscription data.
    Furthermore, the above network may also include the following features: the information indicating whether it is necessary to download user subscription data is a user subscription data download indicator.
    Furthermore, the above network may also include the following features: after the request node receives the network connection request from the user, the network further comprises; that the request node, which detects location information recorded by the user, and user data information, determines whether the aforementioned user subscription data is to be downloaded in accordance with the detection result, and configures a user subscription data download indicator accordingly.
    In addition, the above network may also include the following features: if the user subscription data download indicator in the Update Location Request message received by the HSS indicates that it is not necessary to download user subscription data, then the HSS does not need to return user subscription data to the request node.
    Furthermore, the above network may also include the following features: if the user subscription data download indicator in the Update Location Request message received by the HSS indicates that it is necessary to download user subscription data, and the Update Location Request message includes information about the request node properties, then determines The HSS includes the user subscription data supported by the request node according to the information indicating the properties of the request node, and includes user subscription data in the Update Location Ack message to be returned to the request node.
    Furthermore, the above network may also include the following features: if the user subscription data download indicator in the Update Location Request message received by the HSS indicates that it is necessary to download user subscription data and the Update Location Request message does not include information about request node properties, the HSS assumes that the request node supports all user subscription data, and returns all user subscription data to the request node.
    In addition, the above network may also include the following features: if the user subscription data download indicator in the Update Location Request message received by the HSS indicates the need to download user subscription data, and the Update Location Request message includes information about the request node properties, but the request node does not support user subscription data, which in the opinion of the HSS should be supported, then the HSS includes a rejection as a treatment result and a reason value therefore in the Update Location Ack message.
    Furthermore, the above network may also include the following features: the request node is a Mobility Management Entity (MME).
    Compared to the prior art, the creation proposes, with respect to a network interface based on Diameter network protocol, realization of registration of user location information, download and verification / negotiation of user data between a network node and an HSS using one signaling interaction, i.e. by including capability information, for example, unsupported user subscription data from a request node in a request message, thereby completing user registration.

    FIG. 4 shows a flow in the network for implementing user registration based on Diameter network protocol according to an embodiment of the present invention.
    10 DK 2012 00120 U8 FIG. 5 shows a flow in a user registration to an HSS through an MME in a packet-switched domain according to an embodiment of the present invention.
    The technical thinking behind the present invention will be further described below in detail with reference to the accompanying drawings and examples.
    The main idea behind registering an access request node to an HSS based on Diameter network protocol according to the present invention is that only one signaling interaction is required to complete the process of registering location information, downloading user data and data verification / negotiation, where the request message sent from a request node to an HSS, contains information about the properties of the request node, and the HSS downloads supported user data to the request node according to the information indicating the properties of the request node.
    As shown in FIG. 4, the network arranged to implement user registration based on Diameter network protocol according to an example of the present invention comprises the following steps:
    Step 400, a user creates a network connection request for a visited network domain by creating access through a wireless packet network; wireless packet network, for example, refers to E-UTRAN.
    Step 410, after receiving the network connection request from the user, a request node detects location information and user data information recorded by the user, and determines whether it is necessary to download user subscription data according to the detection result, and configures a user subscription data download intermediate indicator Update Location Request message to the user's HSS, where the Update Location Request message includes a user subscription data download indicator, and when it is necessary to download user subscription data, the Update Location Request message further includes information indicating the properties of the request node 11 DK 2012 00120 U8.
    In practical applications, one is not limited to using a user subscription data download indicator as information indicating whether it is necessary to download user subscription data.
    The request node may refer to an MME.
    The information indicating the properties of the request node may refer to, but not limited to: whether the Update Request message contains information about the properties of the request node.
    When the request node does not support all user subscription data, the Update Location Request message contains information about the properties of the request node; when the request node supports all user subscription data, the Update Location Request message does not contain information about the properties of the request node.
    By information about the properties of the request node is meant a collection of service properties supported by the request node; where the information about the request node's properties includes, but is not limited to, ODB (Operator Data Barring) data, and regional subscription data.
    Step 420, after receiving the Update Location Request message sent by the request node, the user's HSS checks the user; if the check is approved, according to the user subscription data download indicator contained in the Update Location Request message, whether user subscription data should be included in an Update Location Ack message, meanwhile, the Update Location Ack message is returned to the request node; if it is indicated that it is necessary to download user subscription data, the HSS will, according to the information indicating the properties of the request node, determine user subscription data supported by the request node and which includes user subscription data in the Update Location Ack message to be returned to the request node.
    Determining user subscription data supported by the request node according to the information indicating the properties of the request node means determining user subscription data supported by the request node depending on whether the Update Location Request message includes the information indicating the content of the request node. the contained information indicating the properties of the request node and include user subscription data in the Update Location Ack message to be returned to the request node.
    If the user subscription data download indicator shows that it is necessary to download user subscription data, then the HSS must download user subscription data information to the request node.
    If the user subscription data download indicator shows that it is not necessary to download user subscription data, then the HSS does not need to download user subscription data information to the request node.
    The user subscription data contained by the Update Location Ack message includes user subscription data supported in the request node, which is determined by the content of the request node properties information.
    If the user subscription data download indicator in the Update Location Request message indicates that it is necessary to download user subscription data, and the Update Location Request message includes information about the properties of the request node, but user subscription data is not supported (in other words, if the request node does not support user subscription data 's view should be supported), then the HSS returns an Update Location Ack message to the request node, where the Update Location Ack message includes a rejection as a processing result and a reason value therefore.
    If the user subscription data download indicator shows that it is necessary to download user subscription data, and the Update Location Request message sent from the request node to the user's HSS does not include information about the request node's properties, then the HSS assumes that the request node supports all user1120 and returns all user subscription data to the request node.
    The present invention will be further described in the following in connection with a specific example of an embodiment.
    FIG. 5 shows a flow in a user registration to an HSS through an MME in a packet-switched domain according to an embodiment of the present invention, comprising the following steps:
    Step 501, a user creates a network connection request for a visited network domain by creating access through an E-UTRAN;
    Step 502, after receiving the network connection request, an MME detects that the user is initially connected to the network and that the MME has no user data information, the MME configures a user subscription data download indicator and creates an Update Location Request message based on Diameter network protocol for the user's HSS, where the Update Location Request message includes the user subscription data download indicator and information about the properties of the MME, for example, ODB data, regional subscription data, etc.
    Step 503, after receiving the Update Location Request message from the MME, checks the user's HSS user; if the check fails or user roaming is not allowed, the HSS returns an Update Location Ack message to the MME, which includes a denial as a treatment result and a reason value for it; if the control is approved and the user is allowed to roam on the visited network, the HSS determines the user subscription data download indicator covered by the Update Location Request message and performs the following procedures:
    If the user subscription data download indicator in the Update Location Request message requests the download of user subscription data and contains information about the properties of the MME, then the HSS checks the information about the properties of the MME contained in the Update Location Request message and returns an Update Location Request message to the MME, where the Update Location Request message includes a processing result about success, and user subscription data supported by the MME, 14 DK 2012 00120 U8 for example, ODB data, regional subscription data, etc.
    If the user subscription data download indicator in the Update Location Request message requests the download of user subscription data, and the Update Location Request message does not include information about the properties of the MME, then the HSS assumes that the MME supports all user subscription data and returns all user subscription data to MME ' one.
    If the user subscription data download indicator in the Update Location Request message requests the download of user subscription data, and the Update Location Request message includes information about the properties of the MME, but user subscription data is not supported (in other words, if the MME does not support user subscription data 's view should be supported), then the HSS returns an Update Location Ack message to the MME, where the Update Location Ack message includes a rejection as a treatment result and a reason value therefore.
    If the user subscription data download indicator in the Update Location Request message does not request the download of user subscription data, then the HSS returns an Update Location Ack message to the MME, where the Update Location Ack message includes a processing result about success and a reason value therefore.
    The present invention is described with reference to specific embodiments. However, one of ordinary skill in the art can make modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations will be considered as being within the scope of the present invention and the scope of the appended claims.
    The present invention provides a network configured to implement user registration based on Diameter network protocol, where only one signaling interaction is required to implement user location information registration, download and verification / negotiation of user data between a network node and an HSS, by including information about a request node properties in a request message, thereby completing the user registration.
