Invention Patent Descriptive Report for RADIO OPTIMIZATION METHOD LOCATION AND ACCESS NETWORK NODE.
[0001] The present invention relates to the field of communications, and, in particular, to a method of optimization of radio location (paging), apparatus and system.
Background [0002] As communications technologies develop, the Internet of Things has been used extensively in multiple fields such as smart facilities, smart transportation, government affairs, and smart home appliances. Currently, low-cost machine-type communications user equipment (Machine-type Communications User Equipment, EU MTC) has been introduced into a Long Term Evolution network (Long Term Evolution, LTE), with a view improve or optimize the LTE network and an aerial interface to the UE MTC. An important application of UE MTC is a smart meter that, for example, can be used to automatically read measurement information such as water, electricity and gas and report the measurement information to a data center. However, such a smart meter is usually installed in a basement of the house, or is insulated by a heavy metal housing. Therefore, in this case, a loss of path between the UE MTC and an evolved NodeB (Evolved Node B, eNodeB) is more severe than a loss of path between a common UE and eNodeB. To ensure that the UE MTC can communicate normally with eNodeB when the loss of path between the UE MTC and eNodeB is severe, an operator proposes to improve coverage by 20 dB compared to an existing LTE network when an LTE network is providing a service to the UE MTC.
Petition 870180129629, of 9/13/2018, p. 4/186
2/95 [0003] On the existing LTE network, for a UE in a native state, when the UE has an incoming service, or for a UE in an inactive state or a connected state, when a system message needs to be changed or an earthquake or tsunami warning or commercial mobile alert service is required, the network needs to radio locate a corresponding UE. A radio localization process is usually as follows: A mobility management entity (Mobility Management Entity, MME) that serves a UE sends a radio location message to all eNodeBs in a tracking area; upon receipt of the radio location message sent by MME, an eNodeB distributes the radio location message to an UE in an eNodeB management range.
[0004] During the implementation of the radio localization process above, if the existing LTE system is used to provide a service to a UE that has a relatively severe loss of travel with an eNodeB, for example, a UE MTC, system coverage Existing LTE needs to be improved. In that case, a radio location message with improved coverage needs to be sent to the UE. If the UE is being located radio in an existing radio localization form, the UE cannot normally receive a radio location message from the system, which causes radio localization failure.
Summary [0005] The modalities of the present invention provide a method of optimizing radio localization, apparatus and system, in order to ensure that a terminal normally receives a radio localization message sent by a system.
[0006] To achieve the above objective, the following technical solutions are used in the modalities of the present invention.

Channel loss information can be received and stored in advance by the core network node.
[0101] 202. Send a first radio location message that carries the channel loss information to an access network node, so that the access network node sends the control information with improved coverage and / or a second radio location message with improved coverage for the terminal according to the first radio location message; or, send a first radio location message and the channel loss information from the terminal to an access network node, so that the access network node sends control information with improved coverage and / or a second access message. radio location with improved coverage for the terminal according to the first radio location message and the channel loss information from the terminal.

[0103] According to the radio localization optimization method provided in the embodiment of the present invention, when a terminal needs to be located, a core network node sends a first radio location message to an access network node; after receiving the first radio location message sent by the core network node, the access network node sends control information with improved coverage and / or a second radio location message with improved coverage to the terminal that needs to be located.

The channel loss information that is between the terminal and the access network node is determined by the terminal and can be a channel loss value, or it can be a range of a channel loss value, or it can be a range index of a lost channel value. Specifically, the channel loss value can be obtained by using the following method: The terminal can perform the measurement in order to obtain RSRP, RSRP and CQI values, and the loss of path value can be obtained by the terminal by calculating a difference between the energy of a cell-specific reference signal on a downlink (Cell-Specific Reference Signals, CRS) sent by eNodeB and the RSRP value, where the terminal can obtain, using the type system information block 2 (Type 2 System Information Block, SIB2), the energy used by eNodeB to send the downlink CRS. ENodeB, a system, or other network side entity can divide the value of the channel loss between the terminal and eNodeB into N bands, where N is a positive integer; and then eNodeB sends the split information to the terminal that the channel loss value is divided into N bands. By using one or more of the following types of messages: a common radio resource control message (Radio Resource Control, RRC), a dedicated RRC message, a
Petition 870180129629, of 9/13/2018, p. 48/186
46/95 control element message (Control Element, CE) medium access control (Medium Access Control, MAC), and a physical layer message that are sent by eNodeB and received by the terminal, the terminal can get the split information that the channel loss value is divided into N ranges. Specifically, the split information includes a parameter used to indicate a value of N and / or a limit parameter used to determine N ranges, where the parameter used to indicate the value of N or the limit parameter used to determine N ranges also they can be a fixed value that is agreed in advance and predetermined. The terminal, eNodeB, or other network side entity can also perform index numbering on the N bands in a way that is agreed in advance, for example, a number of bands of the band index 1 of a value of a loss of channel to the N band index of a channel loss value. For example, if the channel loss value is divided into three bands, that is, N = 3, the three bands can be respectively as follows: track index 1 of a channel loss value: channel loss <= x1 dB; range index 2 of a channel loss value: x1 dB <channel loss <= x2 dB; and range 3 index of a channel loss value: channel loss> x2 dB. In this case, the parameter that indicates the value of N and is included in the division information that can be sent by eNodeB to the terminal can be 3 and / or the limit parameters used to determine the three ranges are x1 and x2; the above parameters 3, x1, and x2 can also be predetermined, so that eNodeB does not need to include these two parameters in the division information. Alternatively, the terminal can determine the N value ranges of the channel loss according to a rule that is agreed in advance with eNodeB or another network side entity, and the rule that is agreed in advance can be a range index of
Petition 870180129629, of 9/13/2018, p. 49/186
47/95 a value of a channel loss, that is, x = fun (channel loss), where fun () indicates a function. Alternatively, the terminal can determine the N channel loss value ranges according to an agreement with the system, eNodeB, or another network side entity. In this way, the terminal can determine a range of the channel loss of the terminal according to the N bands and the value of the channel loss of the terminal that is obtained through the measurement or can determine a range index of the value of the loss of channel.
[0107] 302. The terminal sends the channel loss information to the access network node, sends an IMSI or an S-TMSI to the access network node and determines a transmission parameter according to the loss information of channel.
[0108] When a channel loss between the terminal and the access network node is severe, the terminal can send the determined channel loss information from the terminal to the access network node, and send it to IMSI or S-TMSI from the terminal to the access network node, so that when the terminal needs to be located, the access network node sends control information with improved coverage and / or a second radio location message with improved coverage to the terminal. In addition, to ensure that the terminal can receive control information with improved coverage and / or the second radio location message with improved coverage that is sent by the access network node, the terminal needs to determine the transmission parameter according to the channel loss information. Specifically, in the same way as the access network node, the terminal can determine the transmission parameter according to the channel loss information. For details, reference can be made to a description in step 406. Alternatively, before the terminal determines the transmission parameter according to the channel loss information, the access network node can determine a group of
Petition 870180129629, of 9/13/2018, p. 50/186
48/95 corresponding transmission parameters, according to the different channel loss information, and send the determined group of transmission parameters and a correspondence between the group of transmission parameters and the channel loss information to the terminal by using of a common RRC message, so that the terminal can select a corresponding transmission parameter from the group of transmission parameters according to the terminal's channel loss information.
[0109] 303. Receive, according to the transmission parameter, control information with improved coverage and / or a second radio location message with improved coverage that are sent by the access network node.
[0110] After determining the transmission parameter according to the channel loss information, the terminal can receive, according to the transmission parameter, the control information with improved coverage and / or the second radio location message with improved coverage that are sent by the access network node.
[0111] According to the radio location optimization method provided in the mode of the present invention, a terminal sends channel loss information to an access network node, and sends an IMSI or an S-TMSI to the network node access point, so that when the terminal is being located, the access network node can send control information with improved coverage and / or a second radio location message with improved coverage to the terminal, and the terminal can receive, from according to a transmission parameter that is determined according to the channel loss information, the control information with improved coverage and / or second location radio message with improved coverage that are sent by the access network node. This effectively ensures that,
Petition 870180129629, of 9/13/2018, p. 51/186
49/95 in a case in which a loss of channel between the terminal and the access network node is severe, the terminal can still normally receive a radio location message sent by a network side device.
[0112] Another embodiment of the present invention provides a method of radio location optimization. As illustrated in figure 4, the method can include:
[0113] 401. An access network node that receives channel loss information sent by a terminal.
[0114] For a terminal in an inactive state, when the terminal has a service, or for a terminal in an inactive state and a terminal in a connected state, when a system message needs to be changed or an early warning of an earthquake or tsunami or commercial mobile alert service is required, a network needs to locate a corresponding UE. To ensure that in a case where a loss of channel between the terminal and an eNodeB is severe, the terminal can still normally receive the control information from a radio location message and / or a radio location message that are sent by a system, the system needs to improve the coverage of the control information of a radio location message and / or the radio location message. Neither an MME nor eNodeB is aware of the channel loss situation between the terminal and eNodeB, so that none between MME and eNodeB can determine the improvement of the coverage of the control information of a radio location message and / or a message of radio location for which terminal, or know a specific amount of improved coverage that is necessary to allow the terminal to normally receive control information from a radio location message and / or radio location message; therefore, the modality of the present invention provides a solution: The information
Petition 870180129629, of 9/13/2018, p. 52/186
50/95 control with improved coverage and / or a second radio message location with improved coverage is sent to all terminals, and a specific value for improved coverage that can be provided is determined according to the worst channel loss situation possible. In another aspect, the modality of the present invention additionally provides another solution: Different specific values of improved coverage are calculated according to the different situations of channel loss, so that a terminal needs to report the channel loss information between the terminal and an eNodeB for a device on the network.
[0115] eNodeB receives the channel loss information sent by the terminal. Specifically, the channel loss can include at least one of the following: RSRP, RSRQ, a loss of travel, and a CQI, where the loss of travel is a loss of travel between the terminal and eNodeB. In addition, the channel loss information that is sent by the terminal and received by eNodeB can be a channel loss value, or it can be a range of a channel loss value, or it can be a range index of a channel value. channel loss. For a detailed description of the acquisition of a channel loss value by the terminal, reference can be made to a corresponding description in step 301 in the embodiment of the present invention, and details are not described here again in that embodiment of the present invention. Additionally, after acquiring the channel loss value, the channel loss value range, or the channel loss value range index between the terminal and eNodeB, the terminal can send the value obtained from the channel loss , channel loss value range, or channel loss value range index for eNodeB by using a non-access statement message (Non-Access Statement, NAS), where the NAS message is transparent to eNodeB . In this case, eNodeB can receive channel loss information
Petition 870180129629, of 9/13/2018, p. 53/186
51/95 that is sent by the terminal using the NAS message, but does not analyze the NAS message, where the NAS message can be dedicated, or it can be a message in a fixation process, a message in a process of updating the area. tracking (Tracking Area Update, TAU), or a message in another process. The terminal can also send the value obtained from the channel loss, channel loss value range, or channel loss value range index to eNodeB by using one or more types of the following messages: an RRC message, a CE MAC message, and a physical layer message, so that eNodeB can receive the channel loss information sent by the terminal, where the RRC message can be an RRC connection request message (RRC Connection Request), and the Physical layer message can be a preamble of random access.
[0116] Optionally, before sending the channel loss information from the terminal to eNodeB, the terminal can first determine if the value of the channel loss between the terminal and eNodeB is greater than or equal to a certain limit; and reports the channel loss information from the terminal to eNodeB when the value of the channel loss is greater than or equal to the determined limit, or it does not report the channel loss information from the terminal to eNodeB when the value of the loss of channel channel is below the determined limit.
[0117] 402. The access network node sends the channel loss information from the terminal to a core network node.
[0118] After receiving the channel loss information from the terminal that is sent by the terminal using a NAS message, eNodeB can only extract the NAS message from an RRC layer without processing the content of the NAS message, and performs the conversion protocol; then eNodeB sends the channel loss information received from the terminal to MME by using a message in
Petition 870180129629, of 9/13/2018, p. 54/186
52/95 an eNodeB and MME protocol layer. Alternatively, after receiving the channel loss information from the terminal that is sent by the terminal using one or more types of the following messages: an RRC message, a CE MAC message, and a physical layer message, eNodeB can send the channel loss information for MME by using a message in an eNodeB and MME protocol layer. The message in the eNodeB and MME protocol layer can be an indication of capacity information (Capacity Information Indication).
[0119] 403. The core network node stores an IMSI or STMSI of the terminal associatively with the channel loss information of the terminal.
[0120] The core network node above may be an MME.
[0121] After receiving IMSI from the terminal and the channel loss information from the terminal that are sent by eNodeB, the MME can store the IMSI of the terminal associatively with the channel loss information from the terminal. In the prior art, the core network node can allocate an S-TMSI to the terminal, so that in the mode of the present invention, after receiving the channel loss information from the terminal that is sent by eNodeB, the MME can store the STMSI of the terminal associatively with the terminal's channel loss information. For example, the MME can store the terminal's IMSI or STMSI associatively with the terminal's channel loss information as illustrated in Table 1, where, for example, the channel loss information is a range index of a lost channel value.

[0122] It should be noted that, in the embodiment of the present invention, the IMSI or S-TMSI of the terminal and the channel loss information of the terminal can be stored associatively specifically as shown in Table 1, or associative storage it can be implemented in another form and format, which is not limited in the mode of the present invention.
[0123] 404. The core network node determines, according to a
IMSI or an S-TMSI of the terminal, that the channel loss information of the terminal has been stored.
[0124] The MME can determine, according to an IMSI or an S-TMSI of the terminal, if the channel loss information that is from the terminal and corresponding to the IMSI or S-TMSI of the terminal has been stored, and when determining that the channel loss information from the terminal is available, perform the following steps 405 to 407. Specifically, the MME can perform the determination according to the associative storage between the terminal IMSI or S-TMSI and channel loss information from the terminal terminal.
[0125] Optionally, after determining that the terminal channel loss information has been stored, the core network node can additionally send the terminal's IMSI or S-TMSI and the terminal channel loss information to the terminal access network by using one or more messages in a protocol layer of the access network node, and the core network node, so that the access network node stores the terminal's IMSI or S-TMSI in a way

54/95 associative with the channel loss information of the terminal. This way, when the terminal is being located, the core network node sends a first radio location message to the access network node in a way of sending a radio location message. The access network node analyzes the first radio location message to obtain the IMSI or S-TMSI from the localized radio terminal carried in the first radio location message obtains channel loss information according to IMSI or S-TMSI an association relationship that is between the terminal's IMSI or S-TMSI and the terminal's channel loss information and stored in the access network node; determines a transmission parameter according to the channel loss information; and sends, according to the transmission parameter, the control information with improved coverage and / or a second radio location message with improved coverage to the terminal that needs to be located by the core network node.
[0126] 405. The core network node sends a first radio location message that carries the channel loss information to the access network side, or sends a first radio location message and the channel loss information from the terminal for the access network node.
[0127] If MME determines that channel loss information from the terminal is available, MME can send the first radio location message to all eNodeBs in an MME tracking area, where the first radio location message can carry at least part of the following information: channel loss information corresponding to the terminal's IMSI or S-TMSI that needs to be localized radio, a terminal identity index value, and the terminal's IMSI or S-TMSI. For example, information elements (Information Element, IE) included in the first radio location message that carries

55/95 channel, the terminal identity index value, and the terminal's IMSI or S-TMSI can be illustrated in Table 2, where the last IE is the channel loss information. MME can also send separately the channel loss information from the terminal that needs to be located and the first radio location message to eNodeB, where the channel loss information from the terminal can be notified to eNodeB using a dedicated layer message. eNodeB and MME protocol. If MME determines that the terminal's channel loss information is not available, when the terminal is being located, MME only needs to send the first radio location message to eNodeB according to the prior art.

[0129] 406. The access network node determines a transmission parameter according to the terminal's channel loss information. [0130] After receiving the first radio location message that carries the channel loss information from the terminal or receiving the channel loss information from the terminal, eNodeB can determine the transmission parameter according to the channel loss information received from the terminal, where the transmission parameter can be one or more of the following: an initial frame number, an initial subframe number, an initial time partition number, an initial symbol number that are used for transmitting information control with improved coverage and / or the second radio message location with improved coverage, a first resource block number (Resource Block, RB) and a first occupied subcarrier number for transmission of control information with improved coverage and / or the second radio location message with improved coverage, a number of frames, a number of subframes, a number of time partitions, a number of symbols, a number of RBs, a number of subcarriers that are occupied for transmitting control information with improved coverage and / or the second location radio message with improved coverage, a number of repetitions, a scatter factor, a spread spectrum sequence index, a transmission time slot nesting size (Transmission Time Range, TTI), an aggregation level that are used to transmit control information with improved coverage and / or second radio location message with improved coverage,

[0133] 407. The access network node sends the control information with improved coverage and / or a second radio location message with improved coverage to the terminal according to the transmission parameter.
[0134] The first radio location message carries a terminal identity index value. After determining the transmission parameter, eNodeB can send control information with improved coverage and / or second radio message location with improved coverage to the terminal according to the transmission parameter and the terminal identity index value, where the second radio location message port the IMSI or S-TMSI of the terminal.
[0135] Compared to the control information without improved coverage, the control information with improved coverage corresponds to at least one of the following conditions: more time-domain resources are used to transmit control information with improved coverage compared to the transmission of control information without improved coverage, more frequency resources are occupied for transmission of control information with improved coverage compared to the transmission of control information without improved coverage, the
Petition 870180129629, of 9/13/2018, p. 61/186
59/95 transmission power for transmission of control information with improved coverage is greater than transmission power for transmission of control information without improved coverage, a modulation scheme used for transmission of control information with improved coverage is more robust than a modulation scheme used for transmission of control information without improved coverage, an encoding mode used for transmission of control information with improved coverage is more robust than a coding mode used for transmission of control information without improved coverage , and bits of control information with improved coverage in a transmission are fewer in number than bits of control information without improved coverage in a transmission. In comparison with a second radio location message without improved coverage, the second radio location message with improved coverage matches at least one of the following conditions: more time domain resources are used to transmit the second radio location message with improved coverage compared to the transmission of a second radio location message without improved coverage, more frequency resources are occupied for transmission of the second radio location message with improved coverage compared to the transmission of the second radio location message without improved coverage, energy transmission rate for transmission of the second radio location message with improved coverage is greater than the transmission energy for transmission of the second radio location message without improved coverage, a modulation scheme used for transmission of the second message radio location with improved coverage is more robust than a modulation scheme used to transmit the second radio message

60/95 location without improved coverage, an encoding mode used for transmission of the second radio message location with improved coverage is more robust than an encoding mode used for transmission of the second radio message location without improved coverage, and bits of the second radio location message with improved coverage in one transmission are fewer in number than the bits of the second radio location message without improved coverage in a transmission. Therefore, when a channel loss between the terminal and the access network node is relatively severe, a way of sending control information with improved coverage and / or the second radio location message with improved coverage to the terminal can be used. to ensure that the terminal successfully receives a radio message locating a system.
[0136] Optionally, in a possible implementation form, eNodeB sends the control information of the second radio location message with improved coverage according to the terminal identity index value and the transmission parameter. For example, the control information of the second radio location message with improved coverage is carried out through a tax downlink control channel (Physical Downlink Control Channel, PDCCH) and / or a physical downlink control channel. enhanced (Enhanced Physical Downlink Control Channel, ePDCCH), and cyclic redundancy check (Cyclic Redundancy Check, CRC) of the control information is encrypted by using a temporary radio location identifier (Temporary Network Identifier) Radio Location, P-RNTI); and a second radio message corresponding location with improved coverage is programmed using the control message, so
Petition 870180129629, of 9/13/2018, p. 63/186
61/95 mode to send the second location radio message with improved coverage through a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), according to the transmission parameter. In this way, the terminal can listen to the PDCCH and / or the ePDCCH channel according to the terminal's IMSI and the transmission parameter that is determined according to the terminal's channel loss information; decrypt CRC from PDCCH and / or ePDCCH by using P-RNTI; and checking control information with improved coverage by using CRC, in order to determine whether control information with improved terminal coverage is available. If control information with improved coverage of the terminal is available, the terminal reads a second radio message corresponding location with improved coverage according to the programming of the control information and transmission parameter and determines, according to IMSI or an STMSI of a terminal that is carried on the second radio location message with improved coverage, if the second radio location message is a radio location message for the terminal itself. If the first radio location message received by eNodeB does not carry the channel loss information from the terminal, or only the first radio location message sent by MME is received, but the channel loss information from the terminal is not received, eNodeB sends the control information of the second radio location message and the second radio location message to the terminal according to the prior art. In this case, the terminal only needs to calculate a corresponding PF and PO according to the IMSI of the terminal, and receive, via PF and in PO, the control information of the second radio location message and the second location message.

This effectively ensures that, in a case in which a loss of channel between the terminal and the access network node is severe, the terminal can still normally receive a radio location message sent by a system.
[0138] The terminal can report in advance the channel loss information between the terminal and the access network node to the system, so that the system can acquire a transmission parameter from the terminal according to the channel loss information from the terminal, and then send control information with improved coverage and / or a radio location message with improved coverage according to the terminal's transmission parameter, which saves network resources.

Specifically, the terminal can send the channel loss information to eNodeB using one or more types of the following messages: an RRC message, a CE MAC message, and a physical layer message, where the RRC message can be a message RRC connection request (RRC Connection Request) and the physical layer message can be a random access preamble. The terminal can send to the eNodeB using an access statement message (Access Statement, AS), the terminal's IMSI or the S-TMSI allocated to the terminal by the core network node, where the access can be an RRC Connection Request. In this case, eNodeB can receive the IMSI or S-TMSI sent by the terminal and the channel loss information sent by the terminal.
[0143] Optionally, before sending the terminal's IMSI or S-TMSI to eNodeB, the terminal can first determine whether a channel loss value between the terminal and eNodeB is greater than or equal to a given limit; and reports the channel loss information from the terminal and the IMSI or S-TMSI of the terminal to eNodeB when the value of the channel loss is greater than or equal to the determined limit,

In a case in which the value of the channel loss is equal to the determined limit, the reporting of the channel loss information can be determined according to a real network condition, which is not limited in the mode of the present invention.
[0144] Optionally, the terminal can send the channel loss information to eNodeB as follows: and the core network node can allocate the S-TMSI to the terminal, and send the S-TMSI allocated to eNodeB by using of a message in a protocol layer of an MME and eNodeB. In this case, eNodeB can receive channel loss information sent by the terminal and S-TMSI from the terminal sent by the MME.
[0145] Optionally, the embodiment of the present invention can additionally include step 401 to step 404. Additionally, if MME determines that the channel loss information of the terminal has been stored, MME can send the terminal's IMSI or S-TMSI and the terminal loss information for eNodeB by using a message in the MME and eNodeB protocol layer. In this case, eNodeB can receive IMSI or S-TMSI from the terminal and the channel loss information from the terminal which are sent by MME.
[0146] 502. The access network node stores the terminal's IMSI or S-TMSI associatively with the terminal's channel loss information.
[0147] After eNodeB receives IMSI or S-TMSI sent by the terminal and channel loss information sent by the terminal, or after eNodeB receives IMSI or S-TMSI from the terminal sent by MME and channel loss information from terminal sent by MME, or after eNodeB receives the channel loss information sent by the terminal and the S-TMSI of the terminal sent by MME, eNodeB can

65/95 store the IMSI or S-TMSI received from the terminal associatively with the channel loss information from the terminal. For a specific storage format, reference can be made to the way in which MME stores the terminal's IMSI or S-TMSI and the terminal channel loss information in step 403, and details are not described here again in the embodiment of the present invention.
[0148] 503. The access network node receives a first radio location message sent by the core network node.
[0149] When the system needs radio to locate the terminal, the MME serving the terminal can send the first radio location message to all eNodeBs in a tracking area.
