[0003] This application relates to the field of communications, and more specifically, to a method and apparatus for paging user equipment, a program product, and a storage medium. Background Technology

[0004] With the rapid development of mobile communication technology, space and terrestrial networks have formed two independent communication networks. To achieve efficient resource sharing and interconnection, space-terrestrial integrated networks have become a new global development trend. When downlink data or signaling is available on the network side, the core network locates the corresponding base station based on the user's previously registered Tracking Area Code (TAC), and the base station sends a paging message to page the user until the user is found. However, to protect user privacy, the user's reported location information needs to be obfuscated to avoid leaking the precise location. After receiving the obfuscated location information reported by the user, the base station needs to further obfuscate the information before reporting it to the core network. While this double obfuscation enhances privacy protection, it also introduces a problem: the accuracy of paging user devices is significantly reduced. Summary of the Invention

[0037] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] First, the relevant technologies involved in this application will be explained:

[0040] For traditional terrestrial 5G networks, registration is the first process performed after a user device (UE) is powered on. Through registration, the UE can connect to the network and obtain services. The core network supports UE registration, including initial registration, mobility registration, and periodic registration.

[0041] For initial registration, when a user initially registers with the 5G network, the Radio Access Network (RAN) selects the appropriate Access and Mobility Management Function (AMF). The AMF supports user equipment authentication based on the subscription authentication information in the Authentication Server Function (AUSF), obtains mobility management subscription data from the Unified Data Management (UDM), and registers its own identifier with the UDM to complete the registration request. The AMF establishes a Mobility Management Context (MM context) for the user equipment and changes the user equipment's mobility state to Registered State (RM-REGISTERED).

[0042] For mobility registration, when the AMF assigns a registration area to a user equipment (UE), and the UE moves or other circumstances cause a change in its Tracking Area Identifier (TAI), or when the UE needs to update its capabilities or other parameters and needs to negotiate through the registration process, the UE initiates a Tracking Area Update (TAU) procedure to report its current TAI to the network. Traditional location registration schemes use a TAI-based TAIU scheme, as shown in Figure 1. In Figure 1, TAI1 in TAI List 1 corresponds to a group of base stations. To reduce paging, multiple TAIs form a Tracking Area Identity List (TAI List). The registration process is initiated during initial UE registration, mobility update (TAI change) registration, periodic registration, and emergency registration. A TAIU is triggered when the UE's assigned TAI List changes. The network locates the user through paging, performing paging on a cell-by-cell basis within the area corresponding to the TAI List.

[0043] For periodic registration, the AMF supports issuing periodic registration update durations to user equipment (UEs) during the initial registration, mobility registration, and periodic registration processes. When the periodic registration update duration expires, UEs in Connection Mode – Idle (CM-IDLE) update the network indicating that the UE is still reachable, and the AMF can process the periodic registration update requests initiated by the UE. After user registration is complete, when the user is in CM-IDLE state and the network needs to send data or signaling to the UE, a paging process is triggered. When the UE is in Connection Mode – Connected (CM-CONNECTED), the paging process can also be used to activate specified Protocol Data Unit (PDU) sessions and establish a UE plane connection for data transmission. The traditional paging process for UEs is shown in Figure 2, including the following steps:

[0044] S202, The User Plane Function (UPF) receives Downlink Data from the Packet Data Network (PDN).

[0045] S204, the UPF reports to the Session Management Function (SMF) via Data Notification that there is Downlink Data on the network side that needs to be forwarded to the target UE.

[0046] S206, SMF calls AMF's Namf_Communication_N1N2Message Transfer NAMF (i.e., message conversion service) to communicate N1 / N2 message conversion, so that N1 and N2 interface messages can be sent to the second base station through AMF.

[0047] S208, AMF finds the corresponding base station based on the TAC (TAC is included in TAI) previously registered by the user equipment.

[0048] S210, AMF sends a paging message to the corresponding base station.

[0049] S212, the base station pages the user equipment within the TAC range previously registered with the user equipment until the user equipment is found.

[0050] S214, a service request is executed between the core network, the target UE, and S-gNB2. The service request is a request initiated by the target UE to the network in the 5G network to request the establishment or continuation of data transmission service.

[0051] S216 After the core network, the target UE and S-gNB2 execute the service request, the target UE receives the downlink data sent from the PDN.

[0052] In traditional location-based paging schemes, user equipment (UE) fuzzes its own location information, with a fuzzing error of approximately 2 kilometers. After receiving the location information reported by the UE, the base station further fuzzes it before reporting it to the core network, resulting in a fuzzing error of approximately 10 kilometers. This fuzziness can cause the core network to obtain a position from the TAC (Target Acquisition Code) reported by the base station that corresponds to an adjacent position to the UE's actual location, as shown in Figure 3. Due to the deviation caused by the fuzzy location, the UE's location may exist in multiple positions during core network paging calculations, leading to paging errors and low paging efficiency.

[0053] The methods and embodiments provided in this application can be executed in a mobile terminal, computer terminal, or similar computing device. Taking a mobile terminal as an example, FIG4 is a hardware structure block diagram of a mobile terminal for a method of paging a user equipment according to an embodiment of this application. As shown in FIG4, the mobile terminal may include one or more (only one is shown in FIG4) processors 402 (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 404 configured to store data. The mobile terminal may also include a transmission device 406 configured for communication functions and an input / output device 408. Those skilled in the art will understand that the structure shown in FIG4 is only illustrative and does not limit the structure of the mobile terminal. For example, the mobile terminal may also include more or fewer components than shown in FIG4, or have a different configuration than that shown in FIG1.

[0054] The memory 404 may be configured to store computer programs, such as application software programs and modules, like the computer program corresponding to a paging user equipment method in this embodiment. The processor 402 executes various functional applications and data processing by running the computer program stored in the memory 404, thereby implementing the aforementioned method. The memory 404 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 404 may further include memory remotely located relative to the processor 402, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0055] The transmission device 406 is configured to receive or transmit data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 406 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 406 may be a Radio Frequency (RF) module configured to communicate with the Internet wirelessly.

[0056] This embodiment provides a method for paging a user equipment. Figure 5 is a flowchart of a method for paging a user equipment according to an embodiment of this application. As shown in Figure 5, the process includes the following steps:

[0057] Step S502: Receive first wavelet information sent by the first base station, wherein the first wavelet information is determined by the first base station based on the location information of the target user equipment, and the first base station is the base station that communicates between the target user equipment and the core network after the connection is established.

[0058] In one exemplary embodiment, the first base station may be a Serving Geostationary NodeB (S-gNB).

[0059] In one exemplary embodiment, the first wave position information includes, but is not limited to, the wave position identifier of the wave position where the target user equipment (UE) is located.

[0060] In an exemplary embodiment, the first wavelet information is the wavelet information of the latest location information reported by the target UE to the first base station when the connection between the target UE and the core network is in a connected state but not yet in an idle state.

[0061] In one exemplary embodiment, the connection relationship between the target UE and the core network includes, but is not limited to, CM-IDLE and CM-CONNECTED. The connected state can be CM-CONNECTED.

[0062] Step S504: Determine the target paging area of ​​the target user equipment based on the first wave position information mentioned above.

[0063] Step S506: Send target paging messages to N second base stations respectively. The target paging messages include the device identifier of the target user equipment and the target wave position information of the target paging area. The target paging messages are used to page the target user equipment in the N second base stations, where N is a positive integer.

[0064] In one exemplary embodiment, the second base station may be an S-gNB.

[0065] In one exemplary embodiment, the device identifier of the target UE can be a 5G Globally Unique Temporary Identifier (5G-GUTI), a temporary identifier used to uniquely identify the UE in the 5G network, assigned by the AMF, for the network to quickly identify the UE. The device identifier of the target UE can also be a Subscription Concealed Identifier (SUCI), an identifier that protects user privacy, generated encrypted based on the user's Subscription Permanent Identifier (SUPI). Alternatively, the device identifier of the target UE can be a Permanent Equipment Identifier (PEI), used to identify the UE's device.

[0066] The paging method for the user equipment shown in Figure 5 will be described below with reference to a specific example. In this embodiment, S-gNB1 (corresponding to the first base station mentioned above) sends a wavelet identifier 0000 0000 0000 0000 0000 0001 to AMF. This wavelet identifier 0000 0000 0000 0000 0000 0001 is an identifier obtained by S-gNB1 after processing the latest location information reported by the target UE when it determines that the connection between the target UE and the core network is in a connected state. AMF uses the wavelet identifier 0 ... 0001 Determine the target paging area of ​​the target user equipment; AMF sends target paging messages to S-gNB2, S-gNB3 and S-gNB4 (corresponding to the above N second base stations), respectively. S-gNB2, S-gNB3 and S-gNB4 page the target UE according to the device identifier of the target UE and the wave position identifier included in the target paging area.

[0067] Furthermore, when the connection between the target UE and the core network changes from a connected state to an idle state, the target UE's location may change, which in turn will cause its wave position identifier to change, for example, to 0000 0000 0000 0000 0000 0010. (In this embodiment, the wave position area identified by the wave position identifier 0000 0000 0000 0000 0000 0010 is only under the coverage of S-gNB2.) In this case, the target UE can only be paged by S-gNB2, and S-gNB3 and S-gNB4 cannot page the target UE. It should be noted that the above content is only an example of this application. Ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of this application should be included within the protection scope of this application. For example, the number of second base stations is not limited to the above 3, but can also be 5, 7 or more. The wavelet identifier of the target UE is not limited to the above binary number, but can also be identified by other parameters, such as Arabic numerals, English characters, etc.

[0068] In this embodiment, the entity performing the above steps may be an Access and Mobility Management Function (AMF), a processing network element or system integrated with an AMF, a network element or system associated with an AMF, or other devices or systems with similar processing capabilities.

[0069] Through the above steps, the target paging area for a target user equipment (User Equipment) is determined based on the first wave position information. This first wave position information is related to the location information of the User Equipment. Determining the paging area using wave position information can cover adjacent wave positions that the User Equipment may move to. This wave position-based paging area calculation method, compared to calculations based on fuzzy locations, can more accurately determine the paging area. Therefore, it solves the problem of low accuracy in paging User Equipment in related technologies, achieving the effect of improving the accuracy of paging User Equipment.

[0070] In an exemplary embodiment, receiving first wavelet information sent by a first base station includes: receiving a first signaling message sent by the first base station, wherein the first signaling message is used to indicate that the connection between the target user equipment and the core network has been released; parsing the first signaling message to obtain a first tracking area identifier; and determining the first wavelet information based on the first tracking area identifier.

[0071] In an exemplary embodiment, the first signaling message may be Context Release Complete (i.e., user equipment context release complete message), and the first base station adds the first waveform information to the TAI by reusing the TAI field (corresponding to the first tracking area identifier mentioned above) in the User Location Information (i.e., user location information) information element in Context Release Complete.

[0072] In this embodiment, the wave position identifier (corresponding to the first wave position information mentioned above) can be filled into the TAC to form part of the TAI information element. The number of bytes for the wave position identifier filled in the TAC can be 3 bytes, and the position can be in the 23 bits used to represent the wave position identifier in the TAC, as shown in Figure 6. It should be noted that the above example is only one implementation method. Ordinary variations and substitutions made by those skilled in the art within the scope of this application's technical solution should be included within the protection scope of this application. For example, in practical applications, the number of bytes for the wave position identifier filled in the TAC is not limited to the above 3 bytes, but can also be 4 bytes or 5 bytes.

[0073] The following example illustrates the format of TAI information. As shown in Figure 7, in addition to the UE's TAC1, the UE's TAI information may include at least one of the following: O Spare, Type of list, Number of elements, Mobile Country Code (MCC), and Mobile Network Code (MNC).

[0074] Specifically, the spare, list type, and number of elements can occupy octet1 (i.e., the first byte); the mobile country code can occupy octet2 (i.e., the second byte) and octet3 (i.e., the third byte); the mobile network code can occupy octet3 (i.e., the third byte) and octet4 (i.e., the fourth byte); and TAC1 can occupy octet5 (i.e., the fifth byte), octet6 (i.e., the sixth byte), and octet7 (i.e., the seventh byte).

[0075] Specifically, the spare part can occupy 1 bit, the list type can occupy 2 bits, the number of elements can occupy 5 bits, the mobile country code can occupy 12 bits, the mobile network code can occupy 12 bits, and the TAC can occupy 3 bytes. It should be noted that the above example is only one implementation method. Ordinary variations and substitutions made by those skilled in the art within the scope of this application's technical solution should be included within the protection scope of this application. For example, the position and number of bits occupied by the above information can be adjusted according to actual applications.

[0076] This embodiment obtains the tracking area identifier by parsing the first signaling message sent by the first base station, and reuses the tracking area identifier in the signaling message. This allows the transmission of the first wavelet information without increasing additional signaling overhead, thus achieving the goal of reducing the resource consumption for transmitting the first wavelet information.

[0077] In an exemplary embodiment, before receiving the first signaling message sent by the first base station, the method further includes: when the connection between the target user equipment and the core network changes from a connected state to an idle state, responding to the third signaling message sent by the first base station, and feeding back a fourth signaling message to the first base station based on the third signaling message, wherein the third signaling message is used to request the release of the connection between the target user equipment and the core network, and the fourth signaling message is used to indicate that the connection between the target user equipment and the core network has been released.

[0078] In one exemplary embodiment, the third signaling message may be a UE Context Release Request (i.e., a user equipment context release request). The fourth signaling message may be a UE Context Release Command (i.e., a user equipment context release instruction). This embodiment achieves the goal of improving network resource utilization by releasing resources associated with the target UE when the target UE enters an idle state.

[0079] In an exemplary embodiment, FIG8 is a flowchart of a method for paging a user equipment according to a specific embodiment of the present application. As the core network and the target UE have not communicated for a long time, the connection relationship between the target UE and the core network changes from CM-CONNECTED to CM-IDLE. S-gNB1 triggers the AN Release (i.e., Radio Access Network Release) procedure to terminate the connection between the target UE and the RAN, as shown in FIG8, including the following steps:

[0080] S802, the connection between the target UE and the core network changes from CM-CONNECTED to CM-IDLE. S-gNB1 triggers the AN Release radio access network release procedure, and S-gNB1 begins to release the radio resource control (RRC) connection with the target UE.

[0081] S804, S-gNB1 initiates a UE Context Release Request to the AMF, requesting the release of the connection between the target UE and the core network.

[0082] S806, the AMF responds to the UE Context Release Request by sending a UE Context Release Command to S-gNB1 to instruct S-gNB1 to release the UE Context.

[0083] S808, S-gNB1 sends the target UE's waveform identifier 0000 0000 0000 0000 0000 0001 (i.e., the first waveform information) to the core network by reusing the TAI field (corresponding to the first tracking area identifier mentioned above) in the User Location Information cell of UE Context Release Complete. The target UE's waveform identifier 0000 0000 0000 0000 0000 0001 is the waveform information of the latest location information reported by the target UE to the first base station when the connection between the target UE and the core network is in a connected state and not in an idle state.

[0084] S810, the AMF sends the Nsmf_PDUSession_UpdateSMContext Request (i.e., Information Protocol Data Unit Session Update Context Request) to the SMF, requesting to update or modify the SM Context (i.e., Session Management Context) of the target UE's PDU Session (i.e., Protocol Data Unit Session).

[0085] In step S812, the SMF initiates an N4 Session Modification Request to the UPF via the N4 interface to update the service data forwarding rules on the UPF. The UPF then provides an N4 Session Modification Response to the SMF via the N4 interface. This response contains information on whether the session modification was successful, as well as any possible reasons for failure. If the session modification is successful, the UPF will process and transmit data according to the new configuration or policy.

[0086] S814, the SMF sends the Nsmf_PDUSession_UpdateSMContext Response (i.e., Protocol Data Unit Session Update Context Response) to the AMF, completing the AN Release.

[0087] In an exemplary embodiment, before receiving the first wavelet information sent by the first base station, the method further includes: receiving a second signaling message sent by an initial base station, wherein the initial base station is a base station that communicates with the target user equipment when requesting to establish a connection with the core network, and the second signaling message is used to indicate the wavelet information of the target user equipment; parsing the second signaling message to obtain a second tracking area identifier; determining the initial wavelet information based on the second tracking area identifier, wherein the initial wavelet information is determined by the initial base station based on the initial location information sent by the target user equipment; and establishing a connection between the target user equipment and the core network based on the initial wavelet information.

[0088] In one exemplary embodiment, the initial base station is the base station connected when the target UE registers, and the first base station is the base station when the target UE enters an idle state. During communication, the base station may remain unchanged or may change; therefore, the first base station can be the initial base station or other base stations.

[0089] In one exemplary embodiment, the second signaling message may be a Location Report (i.e., location report information). The initial location information may be Global Navigation Satellite System position information (GNSS position information). The initial position information includes, but is not limited to, the initial position identifier of the position the target UE is in when it requests registration with the core network but has not yet registered. The initial base station adds the initial position information to the TAI by reusing the TAI field (corresponding to the second tracking area identifier mentioned above) in the Location Report.

[0090] In an exemplary embodiment, establishing a connection between the target user equipment and the core network based on the initial waveform information includes: establishing a connection between the target user equipment and the core network based on the fifth signaling message sent by the initial base station and the initial waveform information, wherein the fifth signaling message is used to request the establishment of a connection between the target user equipment and the core network.

[0091] In one exemplary embodiment, the fifth signaling message may be a Registration Request (i.e., a registration request message), wherein the Registration Request includes, but is not limited to, registration type, user identifier, and UE capabilities.

[0092] In an exemplary embodiment, S-gNB1 sends a Registration Request and the initial waveform identifier of the target UE (0000 0000 0000 0000 0000 0010, corresponding to the initial waveform information mentioned above) to the AMF. The AMF responds to the Registration Request and establishes a connection between the target UE and the core network. At this time, the connection relationship between the target UE and the core network is CM-CONNECTED. The initial waveform identifier 0000 0000 0000 0000 0000 0010 is generated by S-gNB1 based on the initial location information sent by the target UE. It should be noted that the above content is only an example of this application. Ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of this application should be included within the protection scope of this application. For example, the initial waveform identifier of the target UE is not limited to being identified by the above binary number, but can also be identified by other parameters, such as Arabic numerals, English characters, etc. This embodiment directly obtains the wave position information of the target UE reported by the base station. The AMF can directly establish a connection relationship with the target UE based on the wave position information of the target UE. The AMF makes corresponding calculations based on the wave position information reported by the base station, which has higher accuracy and lower computational complexity than reporting fuzzy positions, thus achieving the goal of reducing computational complexity.

[0093] In one exemplary embodiment, establishing a connection between a target user equipment and the core network based on a fifth signaling message and initial beam position information sent by an initial base station includes: responding to the fifth signaling message sent by the initial base station; feeding back a sixth signaling message to the target user equipment based on the fifth signaling message, wherein the sixth signaling message is used to indicate the establishment of a connection between the target user equipment and the core network, and the sixth signaling message includes a distance threshold for the target user equipment; receiving the initial beam position information sent by the initial base station; and establishing a connection between the target user equipment and the core network based on the initial beam position information.

[0094] In one exemplary embodiment, the sixth signaling message may be Registration Accept (i.e., registration acceptance information), and the sixth signaling message may be carried in the Initial Context Setup Request (i.e., initial context setup request).

[0095] In one exemplary embodiment, during the process of establishing a connection between the target user equipment and the core network, the target UE receives a sixth signaling message carrying a distance threshold, and monitors the location information of the target UE based on the distance threshold. After the connection between the target user equipment and the core network is established, if the target UE moves or other circumstances cause the target UE's location to exceed the radius of the distance threshold, the target UE initiates a TAU procedure. The base station can reuse the TAI field in the Location Report and add the target UE's current waveform information to the TAI to update the target UE's location information.

[0096] In an exemplary embodiment, FIG9 is a flowchart of a method for paging a user equipment according to a specific embodiment of the present application. The registration implementation process, which establishes a connection between the target UE and the core network, includes the following steps as shown in FIG9:

[0097] S902, the target UE sends a Registration Request to S-gNB1 to request the establishment of a connection between the target UE and the core network. The Registration Request includes, but is not limited to, registration type, user identifier, and UE capabilities.

[0098] The registration types include, but are not limited to, initial registration, mobility registration, and periodic registration.

[0099] The user identifier can be a 5G-GUTI, a temporary identifier used to uniquely identify the UE in a 5G network, assigned by the AMF for rapid network identification of the UE. The user identifier can also be a SUCI, a privacy-protecting identifier generated based on the user's SUCI encryption. Alternatively, the user identifier can be a PEI, used to identify the device of the UE.

[0100] Among them, UE capabilities include, but are not limited to, the radio frequency bands that the UE can support, the uplink and downlink transmission capabilities, the network functions it supports, and security capabilities.

[0101] S904, S-gNB1 forwards the Registration Request to the AMF in the core network to inform the core network that the target UE requests to establish a connection.

[0102] S906, the core network, S-gNB1 and the target UE execute non-access stratum (NAS) identity recognition requests, authentication and other security procedures to obtain identity information from the target UE and verify the target UE's identity.

[0103] S908, after the security procedure is completed, the AMF establishes a NAS security context with the target UE. The AMF initiates an Initial Context Setup Request to S-gNB1. The Initial Context Setup Request includes Registration Accept, and Registration Accept includes the target UE's distance threshold Delta.

[0104] S910, S-gNB1 sends Registration Accept information to the target UE to accept the Registration Request initiated by the target UE.

[0105] In S912, the core network, S-gNB1, and the target UE use the Security Mode Command (SMC) procedure to negotiate and transmit important parameters for integrity and encryption protection, in order to ensure the secure transmission of data during communication.

[0106] S914, after the target UE and S-gNB1 complete the SMC process, the target UE immediately reports the GNSS location information (corresponding to the initial location information mentioned above) to S-gNB1.

[0107] S916, after receiving the GNSS location information reported by the target UE, S-gNB1 converts the GNSS location information into a wavelet identifier (corresponding to the initial wavelet information mentioned above) for the target UE's location. It reuses the TAI field in the Location Report (corresponding to the second tracking area identifier mentioned above), adds the initial wavelet information to the TAI, and reports the target UE's wavelet information to the AMF. The wavelet identifier can be 3 bytes in the TAC, and can be located in the 23 bits used to represent the wavelet identifier in the TAC shown in Figure 6. In addition to the target UE's TAC, the target UE's TAI information may also include at least one of the following: the target UE's standby status, list type and number of elements, mobile country code, and mobile network code. Specifically, the target UE's backup information occupies 1 bit of the first byte of the target UE's TAI information, the list type occupies 2 bits of the first byte of the target UE's TAI information, and the number of elements occupies 5 bits of the first byte of the target UE's TAI information; the target UE's mobile country code occupies 4 bits of the second and third bytes of the target UE's TAI information; the target UE's mobile network code occupies 4 bits of the third byte and the fourth byte of the target UE's TAI information; and the target UE's TAC occupies the fifth, sixth, and seventh bytes of the target UE's TAI information. It should be noted that the above example is only one implementation method, and ordinary variations and substitutions made by those skilled in the art within the scope of this application's technical solution should be included within the protection scope of this application. For example, the positions and number of bits occupied by the above information can be adjusted according to actual applications.

[0108] S-gNB1 also receives GNSS location information reported by other UEs, converts the GNSS location information into wavelet identifiers and fills them into TAC. S-gNB1 manages the UE-TAC correspondence table, as shown in Table 1. TAC includes: TAC#r, TAC#s, ... TAC#t, where TAC#r is obtained by the base station converting the GNSS location information of terminal UE#1, TAC#s is obtained by the base station converting the GNSS location information of terminal UE#2, and TAC#t is obtained by the base station converting the GNSS location information of UE#m.

[0109] Table 1:

[0110] S918, based on the waveform identifier of the target UE's location in the Location Report, the AMF implements access control for the target UE according to the subscription or policy information.

[0111] S920, S-gNB1 sends an Initial Context Setup Response to the AMF (i.e., initial context response request information), indicating that the context establishment between the AMF core network and the target UE is successful and the registration is successful.

[0112] S922, the target UE sends Registration Complete to S-gNB1.

[0113] S924, S-gNB1 receives the Registration Complete message and encapsulates the Registration Complete message into an Uplink NAS Transport (i.e., uplink non-access stratum transport) and forwards it to the AMF to complete the registration.

[0114] In an exemplary embodiment, determining the target paging area of ​​the target user equipment based on the first wave position information includes: determining the wave position of the target user equipment based on the target wave position identifier included in the first wave position information, wherein the target wave position identifier is used to uniquely identify the wave position of the target user equipment; and determining the target paging area based on the wave position of the target user equipment.

[0115] In one exemplary embodiment, determining the target paging area based on the wave position of the target user equipment includes: determining a distance threshold matching the target user equipment; and determining the target paging area based on the wave position of the target user equipment and the distance threshold.

[0116] In an exemplary embodiment, determining the target paging area based on the wave position of the target user equipment and the distance threshold includes: determining the target combined area with multiple vertices of the target wave position as centers and the distance threshold of the target user equipment as a radius, wherein the target combined area includes an area determined based on each vertex as a center; determining the target paging area based on the target combined area, wherein the target paging area is an area externally tangent to the target combined area.

[0117] In an exemplary embodiment, as shown in FIG10, when determining the target paging area, it is necessary to first determine the target area combination. That is, first determine the target combination area based on the six vertices of the target wave position as the center and the distance threshold of the target user equipment as the radius. Based on the area determined by each vertex as the center, the target combination area is obtained. Based on the external tangent of the target combination area, the target paging area is determined, that is, the rectangular area formed by A0-A1-A2-A3 shown in FIG7 is determined as the target paging area.

[0118] In an exemplary embodiment, before sending the target paging message to each of the N second base stations, the method further includes: determining the N second base stations and the second wave position information of the N second base stations based on the target paging area and wave position planning information, wherein the wave position planning information includes information on the wave positions covered by the base stations within a predetermined time period; sending the target paging message to each of the N second base stations includes: sending the target paging message to each of the second base stations based on the second wave position information of each of the second base stations.

[0119] In one exemplary embodiment, based on the plurality of first target wave position identifiers included in the target wave position information, a plurality of first target wave positions covered by the target paging area are determined, wherein the first target wave position identifiers are used to uniquely identify the first target wave positions; based on the plurality of first target wave positions covered by the target paging area and the wave position planning information, N second base stations are determined, wherein the N second base stations cover the plurality of first target wave positions covered by the target paging area; based on the base station identifier of each second base station, a plurality of second target wave positions covered by each second base station are determined, thereby obtaining the second wave position information of the N second base stations, wherein the plurality of second target wave positions covered by the N second base stations include a plurality of the first target wave positions.

[0120] In one exemplary embodiment, the beam position planning information is used to describe the beam position information covered by the base station over a future period of time. The beam position information includes, but is not limited to, the area covered by the base station and the planning of the communication beam when the base station is running on its orbit. For example, base station orbit parameters (orbit type, orbit altitude, orbit location), beam coverage area (beam position identifier, coverage range, beamwidth, frequency range), communication capabilities (downlink parameters, uplink parameters), service type, beam position planning schedule, and factors influencing beam position planning.

[0121] In one exemplary embodiment, the second wave position information includes, but is not limited to, the wave position identifier of the wave position covered by the second base station.

[0122] In an exemplary embodiment, the AMF determines the target paging area of ​​the target user equipment based on the target UE's wavelet identifier 0000 0000 0000 0000 0000 0001 and the target UE's distance threshold. This target paging area includes 10 wavelets. Based on the wavelet identifiers of the 10 wavelets in the target paging area (corresponding to the aforementioned multiple first target wavelets) and the wavelets covered by the base stations in the future period (corresponding to the aforementioned wavelet planning information), three second base stations S-gNB2, S-gNB3, and S-gNB4 (corresponding to the aforementioned N second base stations) and the wavelet identifiers of the wavelets covered by the three sets of second base stations (corresponding to the aforementioned second target wavelets) are determined. Target paging messages are sent to S-gNB2, S-gNB3, and S-gNB4 respectively. S-gNB2, S-gNB3, and S-gNB4 page the target user equipment in the wavelets they cover according to the target UE's device identifier and the wavelet identifiers of the wavelets they cover. For example, if the target UE's wave position identifier changes from 0000 0000 0000 0000 0000 0010 to 0000 0000 0000 0000 0010 (in this embodiment, we take the wave position area identified by the wave position identifier 0000 0000 0000 0000 0000 0010 as an example, which is only covered by S-gNB2), S-gNB2 can page the target UE, while S-gNB3 and S-gNB4 cannot page the target UE. It should be noted that the above content is only an example of this application. Ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of this application should be included within the protection scope of this application. For example, the number of wavelets in the target paging area is not limited to the above 10, but can also be 6 or 20. The number of second base stations is not limited to the above 3, but can also be 5, 7 or more. The wavelet identifier of the target UE is not limited to the above binary number, but can also be identified by other parameters, such as Arabic numerals, English characters, etc.

[0123] This embodiment determines the second base station based on the target paging area and wave position planning information, and clarifies the wave position covered by each base station. This allows paging messages to be sent more accurately to specific base stations that may cover the target UE, reducing the broadcast range of paging messages and achieving the goal of improving paging efficiency.

[0124] This embodiment provides a method for paging a user equipment. Figure 11 is a flowchart of a method for paging a user equipment according to an embodiment of this application. As shown in Figure 11, the process includes the following steps:

[0125] Step S1102: Receive a target paging message, wherein the target paging message is used to instruct the target user equipment to be paging;

[0126] Step S1104: Parse the above target paging message to obtain the target wave position information and the device identifier of the target user equipment.

[0127] Step S1106: Page the target user equipment based on the target wave position information and the device identifier of the target user equipment.

[0128] In one exemplary embodiment, the device identifier of the target UE can be a 5G-GUTI, a temporary identifier used to uniquely identify the UE in a 5G network, assigned by the AMF, for the network to quickly identify the UE. The device identifier of the target UE can also be a SUCI, an identifier that protects user privacy and is generated based on SUPI encryption. Alternatively, the device identifier of the target UE can be a PEI, used to identify the device of the UE.

[0129] In this embodiment, the entity performing the above steps may be a base station, a network element or system associated with the base station, or other devices or systems with similar processing capabilities.

[0130] In one exemplary embodiment, for example, S-gNB2, S-gNB3 and S-gNB4 (corresponding to the N second base stations mentioned above) receive a target paging message sent by AMF. S-gNB2, S-gNB3 and S-gNB4 parse the target paging message to obtain the device identifier of the target UE and the wave position identifier included in the target paging area. Based on the device identifier of the target UE and the wave position identifier included in the target paging area, the target UE is paging. When the connection between the target UE and the core network changes from a connected state to an idle state, the target UE's location may change, which will cause its wave position identifier to change, for example, to 0000 0000 0000 0000 0000 0011. (In this embodiment, the wave position area identified by the wave position identifier 0000 0000 0000 0000 0000 0011 is only under the coverage of S-gNB3.) In this case, the target UE can only be paged by S-gNB3, and S-gNB2 and S-gNB4 cannot page the target UE. It should be noted that the above content is only an example of this application. Ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of this application should be included within the protection scope of this application. For example, the number of second base stations is not limited to the above 3, but can also be 5, 7 or more. The wavelet identifier of the target UE is not limited to the above binary number, but can also be identified by other parameters, such as Arabic numerals, English characters, etc.

[0131] In an exemplary embodiment, receiving a target paging message includes: receiving the target paging message sent by a target network element, wherein the target paging message is sent by the target network element based on a target paging area, the target paging area is the paging area of ​​the target user equipment, and the target paging area is determined by the target network element based on first wavelet information received from a first base station, the first wavelet information is determined by the first base station based on the location information of the user equipment, and the first base station is a base station that communicates between the target user equipment and the core network after a connection is established.

[0132] In one exemplary embodiment, the target network element includes an Access and Mobility Management Function (AMF).

[0133] Through the above steps, the target paging area for a target user equipment (User Equipment) is determined based on the first wavelet information, which is related to the location information of the User Equipment. Determining the paging area using the wavelet information can cover adjacent wavelets that the User Equipment may move to. This wavelet-based paging area calculation method can determine the paging area more accurately than calculations based on fuzzy locations. Since this application directly receives the wavelet information transmitted by the first base station and performs paging based on the wavelet information, it solves the problem of low accuracy in paging User Equipment in related technologies, thus improving the accuracy of paging User Equipment.

[0134] The above embodiments have all described this application from one perspective. For ease of understanding, the application will be described in its entirety below with reference to specific embodiments:

[0135] This embodiment provides a scheme for receiving wavelet information sent by a base station and performing paging based on the wavelet information, which solves the problem of low accuracy in paging user equipment in related technologies and achieves the effect of improving the accuracy of paging user equipment. Specifically, as shown in Figure 12, it includes the following steps:

[0136] S1202, AMF obtains wave position planning information from the operation control system.

[0137] S1204, UPF receives Downlink Data from PDN.

[0138] S1206, the UPF reports to the SMF via Data Notification that there is Downlink Data on the network side that needs to be forwarded to the target UE.

[0139] S1208, SMF calls AMF's Namf_Communication_N1N2Message Transfer NAMF (i.e., N1 / N2 message transfer) to enable the subsequent transmission of N1 and N2 interface messages to the second base station via AMF.

[0140] S1210, the AMF, based on the target UE's wavelet identifier 0000 0000 0000 0000 0000 0001 reported by S-gNB1 in AN Release, and combined with the target UE's distance threshold, determines the target paging area of ​​the target user equipment, which includes 12 wavelets. Based on the wavelet identifiers of the 12 wavelets in the target paging area (corresponding to the aforementioned multiple first target wavelets) and the wavelets covered by the base station in the future period (corresponding to the aforementioned wavelet planning information), determines the wavelet identifiers of the two second base stations S-gNB2 and S-gNB3 and the wavelets covered by the two sets of second base stations (corresponding to the aforementioned second target wavelets).

[0141] In step S1212, the AMF sends paging messages to S-gNB2 and S-gNB3 respectively. The target paging message includes, but is not limited to, the target UE's device identifier and a TAI List. The TAI List reuses the 5G information element format. The TAC is filled with the wavelet identifier contained in the paging area, and the TAC is contained within the TAI. Multiple TAIs are encapsulated into a TAI List, as shown in Figure 13. The TAI List includes: 5G tracking area identity list IEI (i.e., 5G tracking area identifier list IEI), Length of 5GS tracking area identity list content (i.e., the length of the 5GS tracking area identifier list content), Partial tracking area identity list 1 (i.e., partial tracking area list 1), Partial tracking area identity list 2 (i.e., partial tracking area list 2)...Partial tracking area identity list p (i.e., partial tracking area list p). Each Partial tracking area identity list in the figure corresponds to one tracking area identifier (TAI). It should be noted that the number of TIAs encapsulated in the TAI List can be indicated by the number of elements in Figure 6.

[0142] In S1214, S-gNB2 and S-gNB3 parse the TAI List and perform paging based on the corresponding wave position identifier in the TAI List, as well as the device identifier of the target UE and the wave position identifier of the wave position they cover. They then paging the target user equipment within the wave positions they cover. For example, if the wave position identifier of the target UE changes from 0000 0000 0000 0000 0000 0001 to 0000 0000 0000 0000 0010, and it is within the wave position covered by S-gNB2, then S-gNB2 can page the target UE, but S-gNB3 cannot.

[0143] S1216, Service request is executed between the core network, the target UE and S-gNB2.

[0144] S1218 After the core network, the target UE and S-gNB2 execute the service request, the target UE receives the downlink data sent from the PDN.

[0145] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
