[0088] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0089] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0090] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0091] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0092] With the development of network communication technology, IoT-NTN (Internet of Things Non-Terrestrial Network) technology has emerged. IoT-NTN technology is a mobile communication system that supports LTE (Long Term Evolution) network accessed via satellite based on the NB-IoT (Narrowband Internet of Things) standard. Among them, the satellite access method can include satellite transparent transmission mode or satellite regeneration mode. IoT-NTN, an Internet of Things terminal access technology for non-terrestrial networks, is widely used in vertical industries such as shipping, wilderness transportation, energy collection, agriculture, and environmental protection because of its wide coverage and low rate. For IoT-NTN in satellite regeneration mode, the entire system consists of terminals, satellite regeneration payloads (such as base station eNodeB, ground mobility management entity MME (Mobility Management Entity), SGW (Serving GateWay), etc.), satellite gateways, core networks and service servers. Depending on different networking conditions, the functions included in the satellite regeneration payload are different. For example, it can have eNodeB network element functions, or it can also have eNodeB and MME network element functions. The system focuses on supporting satellite IoT services for low-complexity eMTC (LTE enhanced MTO, IoT technology based on LTE evolution) and IoT terminals, mainly for scenarios such as shipping, energy collection, global asset tracking, and environmental monitoring, providing reliable data transmission services for various low-rate, low-frequency, and low-cost IoT applications.

[0093] Based on this, the industry is studying IoT-NTN storage and forwarding technology based on the regeneration mode of medium and low orbit satellites. When terminals access the NTN storage and forwarding scenario, it is necessary to consider the network's location verification requirements for the terminal. Therefore, how to verify the location of the IoT-NTN terminal when it accesses the network has become a technical problem that needs to be urgently solved in the current communication technology field.

[0094] For IoT-NTN technology in medium and low orbits, in the early stage of network construction, due to the limited number of satellites and gateways, there is a situation where the satellite's service link and feeder link cannot be available at the same time, which results in IoT-NTN being unable to provide communication services to terminals within the satellite coverage area at certain times. However, the current standard process requirements are all based on the IoT-NTN scenario where both the satellite feeder link and the service link are available at the same time, and are not applicable to the NTN storage and forwarding scenario where only one of the feeder link or the service link is available.

[0095] The location verification method provided in the embodiment of the present application can be applied to Figure 1 In the communication system shown. The communication system includes satellite network elements, terminals (UE, User Equipment), ground mobility management entities MME (Mobility Management Entity), ground location management servers and HSS (Home Subscriber Server) that can communicate with each other, wherein the ground mobility management entity MME can be referred to as ground MME, and the satellite network elements can include but are not limited to satellite base stations eNodeB, etc. The satellite eNodeB is an LTE base station functional entity located on the satellite. The functional entity is used to obtain the rough location information of the terminal, so it is configured with satellite coverage cell information that requires the network to verify the terminal location, and has the positioning measurement function of judging whether it is necessary for the network to verify the terminal location information and implementing the network verification of the terminal location. The ground mobility management entity is an LTE MME functional entity located in the ground network, which is used to perform mobility and session management on the terminal, and is configured with terminal mobility management rules and information on geographical location areas that the terminal is not allowed to access, so as to determine whether the terminal is allowed to access based on the terminal location information. The ground location management server (LMF, Location Management Function) is used to interact with the ground mobility management entity to calculate the terminal's location information based on the terminal's measurement report and positioning measurement configuration information. The HSS is used to interact with the ground mobility management entity to implement terminal authentication. The terminal supports the network access function of the NTN store-and-forward scenario, and can carry the attachment request and the indication information of whether the terminal supports the network's ability to verify the terminal's location in the radio resource control connection establishment completion message. Among them, the terminal can include but is not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0096] Those skilled in the art will understand that Figure 1 The structure shown in the figure is only a block diagram of a partial structure related to the scheme of the present application, and does not constitute a limitation on the network architecture to which the scheme of the present application is applied. The specific network architecture may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0097] In one embodiment, Figure 2 As shown, a location verification method is provided, which is applied to Figure 1 The satellite access element in the communication system in FIG. 1 is taken as an example to illustrate, including the following steps:

[0098] S201, receiving a radio resource control connection establishment completion message sent by a terminal; the radio resource control connection establishment completion message carries an attach request and indication information of whether the terminal supports the ability of the network to verify the terminal location.

[0099] The Radio Resource Control Connection Setup Complete (RRCConnectionSetupComplete) message carries an Attach Request and an indication of whether the terminal supports the ability of the network to verify the terminal's location. The Attach Request is used to indicate whether the terminal needs to be verified. For example, if the Radio Resource Control Connection Setup Complete message (i.e., the RRCConnectionSetupComplete message) carries an indication of the ability of the terminal to support the network to verify the terminal's location, it indicates that the terminal supports location verification; if the Radio Resource Control Connection Setup Complete message does not carry an indication of the ability of the terminal to support the network to verify the terminal's location, it indicates that the terminal does not support location verification. In one embodiment, the satellite network element includes an on-board base station eNodeB (Evolved Node B).

[0100] In the embodiment of the present application, the terminal may send a radio resource control connection establishment completion message to the satellite network element, so that the satellite network element may receive the radio resource control connection establishment completion message sent by the terminal. Optionally, the satellite network element may receive the radio resource control connection establishment completion message sent by the terminal in real time; or, the satellite network element may receive the radio resource control connection establishment completion message sent by the terminal at a fixed time. Of course, the embodiment of the present application does not limit the specific implementation method of receiving the radio resource control connection establishment completion message.

[0102] In the embodiment of the present application, the satellite network element can optionally obtain the location-related information in real time; or the satellite network element can also obtain the location-related information at a fixed time. Of course, the embodiment of the present application does not limit the specific implementation method for obtaining the location-related information.

[0103] The location-related information may include, but is not limited to, TA (timing advance) parameter information determined by the terminal, and / or, UE location information ULI (rough location information of the terminal) determined by the satellite network element, and / or, beam information of the service satellite, and / or, configuration information of the satellite network element, etc. The timing advance parameter information refers to the RTT (round-trip time) between the terminal and the uplink time synchronization reference point calculated by the terminal according to the GNSS (Global Navigation Satellite System) physical position, ephemeris and public TA parameters, and the RTT pre-compensation value set autonomously between the terminal and the uplink time synchronization reference point. The user location information ULI may include, but is not limited to, eNodeB CGI (Common Gateway Interface) and TAI (Tracking Area Identity) parameter information, etc. The configuration information of the satellite network element is used to determine whether the terminal needs to be verified in position in conjunction with the radio resource control connection establishment completion message.

[0104] S203, performing communication processing on the terminal according to the radio resource control connection establishment completion message and location-related information; the communication processing process includes a location verification process.

[0105] In the embodiment of the present application, the satellite network element can determine whether the terminal needs to be position verified based on the radio resource control connection establishment completion message and location-related information, and / or the satellite network element can also determine whether the terminal supports location verification based on the radio resource control connection establishment completion message. Thus, optionally, if the satellite network element determines that the terminal needs to be position verified and the terminal supports location verification, the satellite network element can verify the location of the terminal; if the satellite network element determines that the terminal does not need to be position verified, or the terminal does not support location verification, the satellite network element may not verify the location of the terminal. Of course, the embodiment of the present application does not limit the specific implementation method of the communication processing of the terminal.

[0106] In the above-mentioned location verification method, a radio resource control connection establishment completion message sent by a terminal is received; the radio resource control connection establishment completion message carries an attachment request and an indication of whether the terminal supports the ability of the network to verify the terminal location; location related information is obtained; the location related information includes timing advance parameter information determined by the terminal, and / or, user location information determined by the satellite network element, and / or beam information of the service satellite, and / or configuration information of the satellite network element; communication processing is performed on the terminal according to the radio resource control connection establishment completion message and location related information; the communication processing process includes a location verification process. In the embodiment of the present application, the satellite network element can determine whether the satellite network element needs to perform location verification on the terminal and / or whether the terminal supports location verification according to the received radio resource control connection establishment completion message and the acquired location related information by receiving the radio resource control connection establishment completion message sent by the terminal, thereby accurately verifying the location of the terminal according to whether the satellite network element needs to perform location verification on the terminal and / or whether the terminal supports location verification, so that the location of the terminal can be verified when the IoT-NTN terminal accesses the network.

[0107] In one embodiment, a method for implementing communication processing on a terminal is provided, namely, "performing communication processing on the terminal according to the radio resource control connection establishment completion message and location related information" in the above S202, such as Figure 3 As shown, including:

[0108] S301, determining whether the satellite network element needs to perform location verification on the terminal according to the radio resource control connection establishment completion message and location related information, and obtaining a determination result.

[0109] Among them, the location-related information may include the configuration information of the satellite network element, etc. In one embodiment, the configuration information of the satellite network element may include cell information and physical location area information that the terminal is not allowed to access; the cell information includes satellite cell information that requires network verification of the terminal location information, or satellite cell information that does not require network verification of the terminal location information. In the embodiment of the present application, the satellite network element can compare the radio resource control connection establishment completion message and the location-related information to determine whether the terminal is located within the satellite coverage cell range where the terminal location needs to be verified, thereby determining whether it is necessary to verify the terminal location information through the network, that is, determining whether the satellite network element needs to perform location verification on the terminal and obtain a determination result. Optionally, if the satellite network element determines that the terminal is located within the satellite coverage cell range corresponding to the satellite cell information where the terminal location needs to be verified, it is determined that the terminal location information needs to be verified through the network. At this time, the obtained determination result indicates that the satellite network element needs to perform location verification on the terminal; if the satellite network element determines that the terminal is not located within the satellite coverage cell range corresponding to the satellite cell information where the terminal location needs to be verified, it is determined that the terminal location information does not need to be verified through the network. At this time, the obtained determination result indicates that the satellite network element does not need to perform location verification on the terminal.

[0110] S302: Perform communication processing on the terminal according to the determination result.

[0111] In the embodiment of the present application, optionally, if the determination result indicates that the satellite network element does not need to perform location verification on the terminal, the satellite network element may not verify the location of the terminal; if the determination result indicates that the satellite network element needs to perform location verification on the terminal, the satellite network element may further determine whether the terminal supports location verification, and determine whether to verify the location of the terminal based on the judgment result of whether the terminal supports location verification, that is, if the satellite network element further determines that the terminal supports location verification, the satellite network element may verify the location of the terminal; if the satellite network element further determines that the terminal does not support location verification, the satellite network element may not verify the location of the terminal. Of course, the embodiment of the present application does not limit the specific implementation method of performing communication processing on the terminal.

[0112] In this embodiment, based on the wireless resource control connection establishment completion message and location-related information, by comparing the configuration information of the satellite network element itself, it can be accurately determined whether the satellite network element needs to perform location verification on the terminal, and a determination result can be obtained, so that communication processing of the terminal can be accurately performed based on the determination result.

[0113] In one embodiment, a method for implementing communication processing on a terminal is provided, namely, "performing communication processing on the terminal according to the determination result" in the above S302, such as Figure 4 As shown, including:

[0114] S401, determining whether a determination result indicates that the satellite network element needs to perform location verification on the terminal.

[0115] S402: If the determination result indicates that the satellite network element needs to perform location verification on the terminal, further communication processing is performed on the terminal according to the indication information of whether the terminal supports the network location verification capability of the terminal carried in the radio resource control connection establishment completion message.

[0116] In the embodiment of the present application, if the determination result indicates that the satellite network element needs to perform location verification on the terminal, the satellite network element can further determine whether the terminal supports location verification based on the indication information of whether the terminal supports the network verification terminal location capability carried in the radio resource control connection establishment completion message, and determine whether to verify the location of the terminal based on the judgment result of whether the terminal supports location verification. Optionally, if the satellite network element further determines that the terminal supports location verification, the satellite network element can verify the location of the terminal; if the satellite network element further determines that the terminal does not support location verification, the satellite network element may not verify the location of the terminal.

[0117] S403, if the determination result indicates that the satellite network element does not need to perform location verification on the terminal, then when the currently available transmission link is a service link, the attachment acceptance message is encapsulated into the wireless resource control connection reconfiguration message, and the attachment acceptance message is sent to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal.

[0118] In an embodiment of the present application, if the determination result indicates that the satellite network element does not need to perform location verification on the terminal, the satellite network element can encapsulate the attachment acceptance message into the wireless resource control connection reconfiguration message (i.e., RRCConnectionReconfig message, full name Radio Resource ControlConnection Reconfig message) when the currently available transmission link is a service link, obtain the encapsulated wireless resource control connection reconfiguration message, and send the encapsulated wireless resource control connection reconfiguration message to the terminal, and the attachment acceptance message can be sent to the terminal.

[0119] In one embodiment, before "sending the attachment acceptance message to the terminal" in S403, the location verification method further includes:

[0120] The radio resource control connection establishment completion message is saved, and an attach process suspension message is sent to the terminal.

[0121] When the currently available transmission link is a feeder link, the satellite network element sends an initial terminal message to the ground mobility management entity to instruct the ground mobility management entity to return an attachment acceptance message to the satellite network element; the initial terminal message carries an attachment request and an indication that the network does not need to verify the terminal location.

[0122] In the case that the currently available transmission link is a service link, the satellite network element pages the terminal so that the terminal resumes the attachment process.

[0123] In an embodiment of the present application, if it is determined that the satellite network element does not need to perform location verification on the terminal, the satellite network element can save the radio resource control connection establishment completion message and send an attachment process suspension message to the terminal. Since the currently available transmission link includes a feeder link and a service link, the satellite network element can determine whether the currently available transmission link is a feeder link or a service link. In the case where the currently available transmission link is a feeder link, that is, when the feeder link is available, the satellite network element can send an initial terminal message (i.e., Initial UE Message) to the ground MME to instruct the ground mobility management entity to return an attachment acceptance message to the satellite network element. Thus, the satellite network element can receive the attachment acceptance message sent by the ground mobility management entity. Afterwards, in the case where the currently available transmission link is a service link, that is, when the service link is available, the satellite network element can page the terminal to enable the terminal to resume the attachment process. At this time, the ground mobility management entity can send the attachment acceptance message to the terminal by sending an encapsulated radio resource control connection reconfiguration message (i.e., RRCConnectionReconfig message) to the terminal. The initial terminal message (ie, Initial UE Message) carries an attach request Attach Request and indication information that the network does not need to verify the terminal location.

[0124] In this embodiment, if the determination result indicates that the satellite network element needs to perform location verification on the terminal, further communication processing can be accurately performed on the location of the terminal according to the indication information of whether the terminal supports the network verification terminal location capability carried in the radio resource control connection establishment completion message. If the determination result indicates that the satellite network element does not need to perform location verification on the terminal, an attach accept message can be sent to the terminal by sending an encapsulated radio resource control connection reconfiguration message to the terminal to notify the terminal that the satellite network element does not need to perform location verification on the terminal at this time.

[0125] In one embodiment, a method for implementing further communication processing of the terminal location is provided, that is, "further communication processing of the terminal according to the indication information of whether the terminal supports the network verification of the terminal location capability carried in the radio resource control connection establishment completion message" in the above S402, such as Figure 5 As shown, including:

[0126] S501, determining whether a radio resource control connection establishment completion message carries indication information that the terminal supports the network's ability to verify the terminal's location.

[0127] S502: If the radio resource control connection establishment complete message carries indication information that the terminal supports the network's ability to verify the terminal's location, then the ground mobility management entity is instructed to verify the terminal's location.

[0128] In the embodiment of the present application, the satellite network element can parse the radio resource control connection setup completion message (i.e., RRCConnectionSetupComplete message) to obtain the parsing result, and determine whether the radio resource control connection setup completion message carries the indication information of the terminal supporting the network verification terminal location capability according to the parsing result. If it is determined that the radio resource control connection setup completion message carries the indication information of the terminal supporting the network verification terminal location capability, it means that the terminal supports the network verification of the terminal location. At this time, the satellite network element can instruct the ground mobility management entity to determine the terminal location information, and verify the terminal location according to the terminal location information.

[0129] S503, if the wireless resource control connection establishment completion message does not carry the indication information of the terminal supporting the network to verify the terminal location capability, then when the currently available transmission link is a service link, the attachment rejection message is encapsulated into the wireless resource control connection reconfiguration message, and the attachment rejection message is sent to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal; the attachment rejection message carries the rejection reason.

[0130] In an embodiment of the present application, if it is determined that the radio resource control connection establishment completion message does not carry the indication information that the terminal supports the network verification of the terminal location capability, it means that the terminal does not support the network verification of the terminal location. At this time, the satellite network element can encapsulate the attachment rejection message into the radio resource control connection reconfiguration message (i.e., RRCConnectionReconfig message) when the currently available transmission link is a service link, obtain the encapsulated radio resource control connection reconfiguration message, and send the encapsulated radio resource control connection reconfiguration message to the terminal, and the attachment rejection message can be sent to the terminal. The attachment rejection message carries the rejection reason.

[0131] In one embodiment, before "sending the attachment rejection message to the terminal" in S503, the location verification method further includes:

[0132] The radio resource control connection establishment completion message is saved, and an attach process suspension message is sent to the terminal.

[0133] When the currently available transmission link is a feeder link, the satellite network element sends an initial terminal message to the ground mobility management entity to instruct the ground mobility management entity to return an attachment rejection message to the satellite network element; the initial terminal message carries an attachment request, an indication that it is necessary for the network to verify the terminal location, and that the terminal does not support the network verification terminal location function; the attachment rejection message carries the rejection reason.

[0134] In the case that the currently available transmission link is a service link, the satellite network element pages the terminal so that the terminal resumes the attachment process.

[0135] In an embodiment of the present application, if it is determined that the satellite network element needs to perform location verification on the terminal, and the radio resource control connection establishment completion message does not carry the indication information that the terminal supports the network to verify the terminal location capability, the satellite network element can save the radio resource control connection establishment completion message and send an attachment process suspension message to the terminal. Since the currently available transmission link includes a feeder link and a service link, the satellite network element can determine whether the currently available transmission link is a feeder link or a service link. In the case where the currently available transmission link is a feeder link, that is, when the feeder link is available, the satellite network element can send an initial terminal message (i.e., Initial UE Message) to the ground mobility management entity to instruct the ground mobility management entity to return an attachment rejection message to the satellite network element, so that the satellite network element can receive the attachment rejection message sent by the ground mobility management entity. Afterwards, in the case where the currently available transmission link is a service link, the satellite network element can page the terminal to enable the terminal to resume the attachment process. At this time, the ground mobility management entity can send the attachment rejection message to the terminal by sending an encapsulated radio resource control connection reconfiguration message to the terminal.

[0136] The initial terminal message Initial UE Message carries an attach request Attach Request, an indication that it is necessary for the network to verify the terminal location and that the terminal does not support the network verification terminal location function, and the attach reject message carries the rejection reason.

[0137] In this embodiment, it can be determined whether RRCConnectionSetupComplete carries the indication information that the terminal supports the network to verify the terminal's location capability. If RRCConnectionSetupComplete does not carry the indication information that the terminal supports the network to verify the terminal's location capability, the attach rejection message can be sent to the terminal by sending an encapsulated radio resource control connection reconfiguration message to the terminal to notify the terminal that the ground mobility management entity needs to perform location verification on the terminal at this time and the terminal does not support location verification. If RRCConnectionSetupComplete carries the indication information that the terminal supports the network to verify the terminal's location capability, the terminal's location can be accurately verified based on the terminal's location information.

[0138] In one embodiment, a method for implementing verification of the location of the terminal is provided, namely, "instructing the ground mobility management entity to verify the location of the terminal" in the above S502, such as Figure 6 As shown, including:

[0139] S601, the satellite network element sends positioning measurement configuration information to the terminal.

[0140] S602: When the currently available transmission link is a service link, the satellite network element performs positioning measurement on the terminal according to the positioning measurement configuration information and generates a measurement report.

[0141] Among them, the positioning measurement configuration information is used to guide the terminal to send an uplink positioning detection reference signal. The positioning measurement configuration information may include but is not limited to the transceiver mode of the positioning reference signal, and / or measurement interval information, and / or measurement window information, etc. The positioning reference signal may include but is not limited to DL-PRS (down link positioning reference signal, downlink positioning reference signal) and UL-SRS (up link Sounding Reference Signal, uplink detection reference signal), etc.

[0142] In an embodiment of the present application, the satellite network element can send positioning measurement configuration information to the terminal, so that the satellite network element can perform positioning measurement on the terminal according to the positioning measurement configuration information when the currently available transmission link is a service link, and generate a measurement report after the positioning measurement is completed. Among them, the measurement report includes at least measurement timestamp, sounding reference signal configuration information, measurement data and other information, and the measurement data may include but is not limited to at least one of the uplink angle of arrival (UL AoA, uplink Angle-of-Arrival), uplink reference signal receiving power (UL-RSRP, up link Reference Signal Receiving Power), UL relative arrival time (UL-RTOA, up link reference signal time of arrival), satellite network element RX-TX (Receive-Transmit, receive data-send data) time difference and other information.

[0143] S603: When the currently available transmission link is a feeder link, the satellite network element sends an initial terminal message to the ground mobility management entity, where the initial terminal message includes an attachment request, a measurement report, and positioning measurement configuration information, so as to instruct the ground mobility management entity to obtain the location information of the terminal through the ground location management server, and instruct the ground mobility management entity to verify the location of the terminal according to the location information of the terminal, obtain a verification result, and instruct the ground mobility management entity to generate a response message according to the verification result;

[0144] The initial UE message Initial UE Message includes an Attach Request, a measurement report and positioning measurement configuration information.

[0145] In the embodiment of the present application, after the positioning measurement is completed, the satellite network element can save the measurement report and the radio resource control connection establishment completion message (i.e., RRCConnectionSetupComplete message), and send an attachment process suspension message to the terminal. In the case where the currently available transmission link is a feeder link, the satellite network element can send an initial terminal message InitialUE Message to the ground mobility management entity (i.e., ground MME) to instruct the ground mobility management entity to obtain the terminal's location information through the ground location management server, that is, it can be understood that after receiving the initial terminal message Initial UE Message, the ground mobility management entity can parse the measurement report and positioning measurement configuration information from the initial terminal message, thereby forwarding the measurement report and positioning measurement configuration information to the ground location management server, and then, the ground location management server can calculate the terminal's location information based on the measurement report and positioning measurement configuration information, and send the terminal's location information to the ground mobility management entity.

[0146] Because in the satellite scenario, the cell diameter coverage may span multiple network management areas, which in turn brings a series of problems to the NTN storage and forwarding network, such as network access restrictions. The national regulatory agency in the satellite coverage area may define a restricted area where network access is not allowed, or the satellite operator does not have a license to provide services in all its coverage areas. For example, data outbound restrictions, most countries restrict the outbound flow of data generated within the country. Based on this, the embodiment of the present application also requires the satellite network element to instruct the ground mobility management entity to verify the location of the terminal to determine whether the location of the terminal is in a geographical location area that the terminal is not allowed to access. That is, it can be understood that the satellite network element can instruct the ground mobility management entity to verify the location of the terminal according to the terminal's location information to obtain a verification result, so that the ground mobility management entity can generate a response message based on the verification result, and the ground mobility management entity can send a response result corresponding to the verification result to the satellite network element.

[0147] The verification result includes an indication that the location of the terminal is in a geographical location area that is not allowed to be accessed, or an indication that the location of the terminal is not in a geographical location area that is not allowed to be accessed. Exemplarily, the satellite network element may instruct the ground mobility management entity to compare the terminal location information with the terminal mobility management rule information, so as to determine whether the terminal location information belongs to a geographical location area that is not allowed to be accessed by the terminal. The terminal mobility management rule information is pre-configured in the ground mobility management entity by the operator, that is, the ground mobility management entity is pre-configured with terminal mobility management rules, and the terminal mobility management rules contain information on geographical location areas that are not allowed to be accessed by the terminal.

[0148] S604, the satellite network element receives the response message sent by the ground mobility management entity, and forwards the response message to the terminal.

[0149] In one embodiment, S604 includes:

[0150] If the verification result indicates that the terminal is located in a geographical location where access is not allowed, an attachment rejection message sent by the ground mobility management entity is received, and if the currently available transmission link is a service link, the attachment rejection message is encapsulated into a wireless resource control connection reconfiguration message, and the attachment rejection message is sent to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal; the attachment rejection message carries the rejection reason.

[0151] If the verification result indicates that the location of the terminal is not in a geographical location area where access is not allowed, an attachment acceptance message sent by the ground mobility management entity is received, and if the currently available transmission link is a service link, the attachment acceptance message is encapsulated into a wireless resource control connection reconfiguration message, and the attachment acceptance message is sent to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal.

[0152] In the embodiment of the present application, if the verification result indicates that the location of the terminal is in a geographical location area that does not allow access, the ground mobility management entity can return a response message of rejecting the terminal's attachment request to the satellite network element, that is, sending an attachment rejection message to the satellite network element, and carrying the rejection reason in the attachment rejection message. Thus, the satellite network element can receive the attachment rejection message sent by the ground mobility management entity, and when the currently available transmission link is a service link, that is, when the service link is available, the satellite network element can page the terminal to enable the terminal to resume the attachment process, and the satellite network element can encapsulate the attachment rejection message into a radio resource control connection reconfiguration message, and send the encapsulated radio resource control connection reconfiguration message to the terminal, thereby sending the attachment rejection message to the terminal.

[0153] If the verification result indicates that the terminal is not in a geographical location area where access is not allowed, the ground mobility management entity can interact with the HSS to perform necessary terminal authentication. After the authentication is passed, the ground mobility management entity can return a response message accepting the terminal attachment request to the satellite network element, that is, send an attachment acceptance message to the satellite network element. Thus, the satellite network element can receive the attachment acceptance message sent by the ground mobility management entity, and when the currently available transmission link is a service link, that is, when the service link is available, the satellite network element can page the terminal to enable the terminal to resume the attachment process, and the satellite network element can encapsulate the attachment acceptance message into the radio resource control connection reconfiguration message, and send the encapsulated radio resource control connection reconfiguration message to the terminal, thereby sending the attachment acceptance message to the terminal.

[0154] In this way, the satellite network element can receive the attachment rejection message or the attachment acceptance message sent by the ground mobility management entity, and can encapsulate the attachment rejection message or the attachment acceptance message into the wireless resource control connection reconfiguration message and then send it to the terminal. In this way, the terminal can be notified whether the terminal's location at this time is in a geographical location area where access is not allowed.

[0155] In this embodiment, the satellite network element can send the positioning measurement configuration information to the terminal, and when the currently available transmission link is the service link, perform positioning measurement on the terminal and generate a measurement report. Thus, the measurement report and the positioning measurement configuration information can be forwarded to the ground position management server through the ground mobility management entity to instruct the ground position management server to calculate the terminal's location information based on the measurement report and the positioning measurement configuration information. Furthermore, the ground mobility management entity can be instructed to accurately verify the terminal's location based on the terminal's location information.

[0156] In one embodiment, a location verification method is provided, which is applied to Figure 1 Taking the ground mobility management entity in the communication system in FIG. 1 as an example, the method includes the following steps:

[0157] If the satellite network element determines that the location of the terminal needs to be verified, and the radio resource control connection establishment completion message carries indication information that the terminal supports the network's ability to verify the terminal's location, the ground mobility management entity verifies the location of the terminal.

[0158] In an embodiment of the present application, if the satellite network element determines that the wireless resource control connection establishment completion message carries indication information that the terminal supports the network verification of the terminal location capability, it means that the terminal supports the network verification of the terminal location. At this time, the satellite network element can instruct the ground mobility management entity to determine the terminal location information, so that the ground mobility management entity can verify the terminal location based on the terminal location information.

[0159] In the above-mentioned location verification method, if the satellite network element determines that location verification needs to be performed on the terminal, and the wireless resource control connection establishment completion message carries indication information that the terminal supports the network's ability to verify the terminal's location, then the ground mobility management entity can accurately verify the terminal's location based on the terminal's location information.

[0160] In one of the embodiments, the ground mobility management entity verifies the location of the terminal, including:

[0161] In the case where the currently available transmission link is a feeder link, an initial terminal message sent by an on-board network element is received; the initial terminal message includes an attachment request, a measurement report and positioning measurement configuration information, and the positioning measurement configuration information includes a positioning reference signal receiving and sending mode information, and / or measurement interval information, and / or measurement window information;

[0162] Sending a measurement report and positioning measurement configuration information to a ground position management server to instruct the ground position management server to calculate the location information of the terminal according to the measurement report and the positioning measurement configuration information, and sending the location information of the terminal to the ground mobility management entity;

[0163] The terrestrial mobility management entity verifies the location of the terminal based on the location information of the terminal.

[0164] In one of the embodiments, the ground mobility management entity verifies the location of the terminal according to the location information of the terminal, including:

[0165] Verifying the location of the terminal according to the location information of the terminal to obtain a verification result;

[0166] A response message is generated according to the verification result, and the response message is sent to the satellite network element to instruct the satellite network element to forward the response message to the terminal.

[0167] In one of the embodiments, the location of the terminal is verified according to the location information of the terminal to obtain a verification result, including:

[0168] A verification result is obtained based on whether the location information of the terminal is in a physical location area that the terminal is not allowed to access.

[0169] In one embodiment, generating a response message according to the verification result, and sending the response message to the satellite network element to instruct the satellite network element to forward the response message to the terminal includes:

[0170] If the verification result indicates that the location information of the terminal is in a physical location area that the terminal is not allowed to access, the ground mobility management entity generates an attachment rejection message and returns the attachment rejection message to the satellite network element to indicate that the satellite network element encapsulates the attachment rejection message into a radio resource control connection reconfiguration message when the currently available transmission link is a service link, and sends the attachment rejection message to the terminal by sending the encapsulated radio resource control connection reconfiguration message to the terminal; the attachment rejection message carries the rejection reason;

[0171] If the verification result indicates that the location information of the terminal is not within the physical location area that the terminal is not allowed to access, the ground mobility management entity generates an attachment acceptance message and returns the attachment acceptance message to the satellite network element to indicate that the satellite network element encapsulates the attachment acceptance message into the wireless resource control connection reconfiguration message when the currently available transmission link is a service link, and sends the attachment acceptance message to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal.

[0172] Among them, the specific implementation methods and beneficial effects corresponding to the above embodiments can be referred to the embodiments on the satellite network element side, which will not be described in detail here.

[0173] In one embodiment, a method for implementing the ground mobility management entity returning an attachment acceptance message to the satellite network element without performing location verification on the terminal is provided, that is, the above-mentioned location verification method, further comprising:

[0174] If the satellite network element determines that it is not necessary to perform location verification on the terminal, the ground mobility management entity returns an attachment acceptance message to the satellite network element to instruct the satellite network element that when the currently available transmission link is a service link, the satellite network element encapsulates the attachment acceptance message into a wireless resource control connection reconfiguration message and sends the attachment acceptance message to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal.

[0175] In an embodiment of the present application, if the satellite network element determines that it is not necessary to perform location verification on the terminal, the ground mobility management entity can receive and normally process the initial terminal message Initial UE Message sent by the satellite network element, and interact with the HSS (Home Subscriber Server) to perform necessary terminal authentication. After the authentication is passed, the ground mobility management entity can return an attachment acceptance message to the satellite network element, so that the satellite network element can receive the attachment acceptance message sent by the ground mobility management entity. Afterwards, when the currently available transmission link is a service link, that is, when the service link is available, the satellite network element can page the terminal to restore the attachment process of the terminal. At this time, the ground mobility management entity can send the attachment acceptance message to the terminal by sending an encapsulated radio resource control connection reconfiguration message to the terminal. Among them, the initial terminal message Initial UE Message carries an attachment request AttachRequest and an indication that the network does not need to verify the terminal location.

[0176] In this embodiment, if the satellite network element determines that it is not necessary to perform location verification on the terminal, the ground mobility management entity can return an attachment acceptance message to the satellite network element to instruct the satellite network element to send the attachment acceptance message to the terminal by sending an encapsulated wireless resource control connection reconfiguration message to the terminal when the currently available transmission link is a service link, thereby notifying the terminal that the satellite network element does not need to perform location verification on the terminal at this time.

[0177] In one embodiment, a method for implementing the ground mobility management entity returning an attachment rejection message to the satellite network element is provided when location verification needs to be performed on the terminal and the terminal does not support location verification, that is, the above-mentioned location verification method, further comprising:

[0178] If the satellite network element determines that it is necessary to perform location verification on the terminal, and the wireless resource control connection establishment completion message does not carry the indication information that the terminal supports the network's ability to verify the terminal's location, the ground mobility management entity returns an attachment rejection message to the satellite network element to instruct the satellite network element that when the currently available transmission link is a service link, the satellite network element encapsulates the attachment rejection message into a wireless resource control connection reconfiguration message, and sends the attachment rejection message to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal; the attachment rejection message carries the rejection reason.

[0179] In an embodiment of the present application, if the satellite network element determines that it is necessary to perform location verification on the terminal, and the wireless resource control connection establishment completion message does not carry indication information that the terminal supports the network's ability to verify the terminal's location, the ground mobility management entity can receive and process the initial terminal message sent by the satellite network element, and return an attachment rejection message to the satellite network element, and carry the rejection reason in the attachment rejection message. Thus, the satellite network element can encapsulate the attachment rejection message into the wireless resource control connection reconfiguration message when the currently available transmission link is a service link, and send the attachment rejection message to the terminal by sending the encapsulated wireless resource control connection reconfiguration message to the terminal; the attachment rejection message carries the rejection reason.

[0180] In this embodiment, if the satellite network element determines that it is necessary to perform location verification on the terminal, and the wireless resource control connection establishment completion message does not carry the indication information that the terminal supports the network to verify the terminal location capability, the ground mobility management entity returns an attachment rejection message to the satellite network element, and carries the rejection reason in the attachment rejection message to indicate to the satellite network element that when the currently available transmission link is a service link, the satellite network element sends the attachment rejection message to the terminal by sending an encapsulated wireless resource control connection reconfiguration message to the terminal, thereby notifying the terminal that the satellite network element needs to perform location verification on the terminal at this time and the terminal does not support location verification.
