[0029] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The embodiments of the present application can be applied to various communication systems, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication system or other communication systems, etc.

[0031] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0032] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0033] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to licensed spectrum or unlicensed spectrum.

[0034] Figure 1 A schematic diagram of a communication system 100 used in the present application is shown as an example. Figure 1 As shown, the communication system 100 mainly includes a terminal device (User Equipment, UE) 101, an access network (Access Network, AN) device 102, an access and mobility management function (Access and Mobility Management Function, AMF) entity 103, a session management function (Session Management Function, SMF) entity 104, a user plane function (User Plane Function, UPF) entity 105, a policy control function (Policy Control function, PCF) entity 106, a unified data management (Unified Data Management, UDM) entity 107, a data network (Data Network, DN) 108, an application function (Application Function, AF) entity 109, an authentication server function (Authentication Server Function, AUSF) entity 110, and a network slice selection function (Network Slice Selection Function, NSSF) entity 111.

[0035] Specifically, in the communication system 100, the UE 101 is connected to the AN device 102 at the access layer through the Uu interface to exchange access layer messages and wireless data transmission, and the UE 101 is connected to the AMF entity 103 at the non-access layer (NAS) through the N1 interface to exchange NAS messages; the AN device 102 is connected to the AMF entity 103 through the N2 interface, and the AN device 102 is connected to the UPF entity 105 through the N3 interface; multiple UPF entities 105 are connected through the N9 interface, the UPF entity 105 is connected to the DN 108 through the N6 interface, and at the same time, the UPF entity 105 is connected to the SMF entity 104 through the N4 interface; the SMF entity 104 is connected to the PCF entity 106 through the N7 interface, the SMF entity 104 is connected to the UDM entity 107 through the N10 interface, and the SMF entity 104 controls the UPF entity 106 through the N4 interface. body 105, at the same time, the SMF entity 104 is connected to the AMF entity 103 through the N11 interface; multiple AMF entities 103 are connected through the N14 interface, the AMF entity 103 is connected to the UDM entity 107 through the N8 interface, the AMF entity 103 is connected to the AUSF entity 110 through the N12 interface, the AMF entity 103 is connected to the NSSF entity 111 through the N22 interface, and at the same time, the AMF entity 103 is connected to the PCF entity 106 through the N15 interface; the PCF entity 106 is connected to the AF entity 109 through the N5 interface; the AUSF entity 110 is connected to the UDM entity 107 through the N13 interface.

[0036] In the communication system 100, the UDM entity 107 is a subscription database in the core network, which stores the subscription data of users in the 5G network. The AMF entity 103 is a mobility management function in the core network, and the SMF entity 104 is a session management function in the core network. In addition to the mobility management of the UE 101, the AMF entity 103 is also responsible for forwarding the session management related messages between the UE 101 and the SMF entity 104. The PCF entity 106 is a policy management function in the core network, which is responsible for formulating the mobility management, session management, charging and other related policies for the UE 101. The UPF entity 105 is a user plane function in the core network, which transmits data with the external data network through the N6 interface and transmits data with the AN device 102 through the N3 interface. After the UE 101 accesses the 5G network through the Uu port, a protocol data unit (PDU) session data connection is established from the UE 101 to the UPF entity 105 under the control of the SMF entity 104, so as to transmit data. The AMF entity 103 and the SMF entity 104 obtain user subscription data from the UDM entity 107 through the N8 and N10 interfaces respectively, and obtain policy data from the PCF entity 106 through the N15 and N7 interfaces.

[0037] In addition, there is also a network exposure function (NEF) entity in the communication system 100, which is used to interface with a third-party application server and transmit information between the core network node and the third-party application.

[0038] It should be noted that the above-mentioned communication system 100 is described by taking the 5G communication system as an example. Of course, the present application can also be applied to other 3GPP communication systems, such as 4G communication systems, or future 3GPP communication systems, and the present application is not limited to this.

[0039] It should be understood that a device having a communication function in a network / system in the embodiments of the present application may be referred to as a communication device.

[0040] The embodiments of the present application describe various embodiments in combination with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, for example, a terminal device in an NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0041] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0042] The above-mentioned AN device 102 can be a device for communicating with a mobile device. The AN device 102 can be an access point (Access Point, AP) in WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a base station (gNB) in an NR network, or a network device in a future evolved PLMN network, etc.

[0043] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell may be a cell corresponding to a network device (e.g., a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0044] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0046] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0047] With the development of mobile communication technology, the terminal devices that access the 3rd Generation Partnership Project (3GPP) mobile communication network are no longer limited to handheld terminal devices. More and more machines and equipment, such as drones, will also become widely used in wireless communication network scenarios. When drones and other devices access the 3GPP network, they are also accessed as terminal devices, such as Figure 2 As shown in the figure, after the UAV (Unmanned Aerial Vehicle, UAV) accesses the 3GPP network, it can establish a connection with the UAV Management Center (Unmanned Aerial System Traffic Management, UTM) through the 3GPP network. UTM is responsible for the management functions such as registration and location tracking of the UAV, and can control the behavior of the UAV, such as flight routes. After the UAV accesses the 3GPP network, it can also establish a connection with the UAV controller through the 3GPP network, and the UAV controller controls the behavior of the UAV.

[0048] During the flight of a drone, UTM, USS or an authoritative third-party entity (TPAE), such as a drone controller belonging to the public security system, may need to identify the identity of drones flying in a specific area. Therefore, how to support the query of the UE list in a specific area is an urgent problem to be solved.

[0049] Figure 3 FIG. 2 is a schematic interactive diagram of a wireless communication method 200 according to an embodiment of the present application. Figure 3 As shown, the method 200 may include at least part of the following:

[0050] S202: A first network device receives a first message sent by a query device, where the first message includes first area information, and the first message is used to request a query for terminals in a first area indicated by the first area information.

[0051] Optionally, in an embodiment of the present application, the first network device may be an existing network device, for example, a network exposure function (NEF) entity, that is, the function of the first network device in the embodiment of the present application may be added to the existing network device, or a new functional entity may be added to interface with a third-party application server and transmit information between the core network node and the third-party application. The present application does not limit this.

[0052] Optionally, the first network device and the query device may directly perform signaling interaction, or may perform signaling interaction through other devices. For example, if the first network device is not an NEF entity, the first network device and the query device may perform signaling interaction through an NEF entity. Specifically, the query device may send the first area information to the NEF entity, and the first NEF entity may forward the first area information to the first network device.

[0053] Optionally, the first message can be used to request a query for a list of terminals in a specific area, where the terminals can be ordinary terminals, such as the various terminal types described in the previous embodiments, or other types of terminals, for example, mechanical equipment, such as drones, etc. The present application is not limited to this.

[0054] Optionally, the query device may be any device having authority to query the location of the terminal, such as UTM, USS or TPAE, etc., but the present application is not limited thereto.

[0055] Optionally, in some embodiments, the method 200 further includes:

[0056] The first network device acquires first information, the first information including information of at least one specific terminal. The first information can be used to determine a list of specific terminals that need to be reported when the query device wants to query specific terminals in the first area.

[0057] For example, in S201a, the first network device may obtain the first information from the query device.

[0058] For another example, in S201b, the first network device may obtain the first information from a second network device. The function of the second network device is described in detail below and will not be described in detail here.

[0059] As a specific implementation, the first network device may obtain the first information from the second network device or the query device during the process of registering to the 3GPP network, or may obtain the first information from the second network device or the query device after registering to the 3GPP network.

[0060] Optionally, the second network device or the query device may send the first information based on a request from the first network device, or may actively send the first information to the first network device, which is not limited in the present application.

[0061] Optionally, in some embodiments, the first information includes at least one of the following:

[0062] identification information of the multiple specific terminals;

[0063] type information of the multiple specific terminals;

[0064] Slice information to which the multiple specific terminals belong;

[0065] Network information to which the multiple specific terminals belong;

[0066] Information of query devices corresponding to the multiple specific terminals.

[0067] Optionally, the identifier of the specific terminal may include, for example, at least one of the following:

[0068] An identifier allocated by the 3GPP network to the specific terminal, such as SUPI or GPSI;

[0069] The identifier of the specific terminal outside the 3GPP network, for example, the identifier of the specific terminal in the aviation management system;

[0070] The mapping relationship between the identifiers of the specific terminal inside and outside the 3GPP network.

[0071] Optionally, the type information of the terminal device may be, for example, an ordinary terminal or a non-ordinary terminal, such as a mechanical device such as a drone.

[0072] Optionally, the slice information to which the specific terminal belongs includes, for example, a slice identifier (Slice ID), single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) and network slice selection assistance information (Network Slice Selection Assistance Information, NSSAI), etc.

[0073] Optionally, the network information to which the multiple specific terminals belong includes, for example, the name of the data network (Data Network Name, DNN) to which the terminals access.

[0074] Optionally, the information of the query device corresponding to the specific terminal includes identification information or address information of the query device to which the specific terminal belongs or is registered, and / or identification information or address information of a query device having authority to manage or query the specific terminal.

[0075] Optionally, in some embodiments, the method 200 further includes:

[0076] S203: The first network device determines second area information according to the first area information, where the second area information may be area information defined by a 3GPP network.

[0077] As an example, if the first area information is area information defined by a 3GPP network, the first area information is determined as the second area information. For example, the first area information may be a cell identifier or a tracking area (TA) identifier, in which case the first area information may be determined as the second area information.

[0078] As another example, if the first area information is not area information defined by the 3GPP network, and can be mapped to the area information defined by the 3GPP network, the area information defined by the 3GPP network mapped by the first area information is used as the second area information. For example, the first area information is a coarse-grained area identifier such as a country or a city. In this case, the first area information can be mapped to one or more area information defined by 3GPP. Therefore, the one or more area information defined by 3GPP to which the first area information is mapped can be determined as the second area information.

[0079] As another example, if the first area information is not the area information defined by the 3GPP network and cannot be mapped to the area information defined by the 3GPP network, in this case, the area information defined by the 3GPP network including the first area can be determined as the information of the second area. For example, the first area information is a finer-grained area identifier, a specific airport, a block, or an area bounded by a certain road, or an area range identified by longitude and latitude. In this case, the first area can be mapped to a second area including the first area, for example, the first area is a block, and the mapped second area is, for example, a TA including the block, wherein the range of the TA is larger than the range of the block.

[0080] Furthermore, in some embodiments, the method 200 may also include:

[0081] S204: The first network device sends a second message to the second network device, where the second message includes the second area information, and the second message is used to request to query terminals in a second area indicated by the second area information.

[0082] Optionally, the second network device may be a network device capable of querying a terminal list of a certain area, such as an Access and Mobility Management Function (AMF) entity.

[0083] In S205, the first network device receives a third message replied by the second network device, wherein the third message includes a first terminal list, and the first terminal list includes terminals in the second area.

[0084] In some embodiments, the first terminal list may include one or more terminal identifiers. For example, the terminal identifier may be a subscription permanent identifier (SUPI) or a generic public user identifier (GPSI), but the present application is not limited thereto.

[0085] Optionally, in some embodiments, the third message may further include a second terminal list, wherein the second terminal list includes terminals that may be in the second area. For example, the terminals that may be in the second area include terminals that are in an idle state and whose registration areas intersect with the second area.

[0086] In some embodiments, the second terminal list may also include one or more terminal identifiers, such as SUPI, or GPSI, etc., but the present application is not limited thereto.

[0087] Optionally, in some embodiments, the method 200 further includes:

[0088] S206: The first network device sends a fourth message to the third network device, where the fourth message includes a query terminal list, and the fourth message is used to request to query location information of terminals in the query terminal list.

[0089] In some embodiments, if the third message includes the second terminal list, or the first area and the second area are different, for example, the second area is larger than the first area, in this case, the specific location of the terminals in the first terminal list and / or the second terminal list can be further determined to the third network device.

[0090] Optionally, the third network device may be a network device capable of querying the location information of the terminal, such as a mobile location center (Gateway Mobile Location Centre, GMLC), etc., but the present application is not limited thereto.

[0091] In some embodiments, the query terminal list may include part or all of the terminal list received by the first network device in the third message.

[0092] As an example, the query terminal list may include the second terminal list, that is, the first network device may only confirm the locations of the terminals in the second terminal list to the third network device.

[0093] As another example, the query terminal list includes a list of all terminals received in the third message.

[0094] For example, the query terminal list includes a first terminal list. In this case, the third message may only include the first terminal device.

[0095] For another example, the query terminal list includes the first terminal list and the second terminal list. In this case, the third message may include the first terminal list and the second terminal list.

[0096] In other embodiments, before the first network device sends a query terminal list to the third network device, the first network device may first filter out terminals with identities as specific terminals based on the terminal list in the third message combined with the first information, and further query the third network device for only the location information of the specific terminal.

[0097] In some scenarios, if the query device wants to query a specific terminal in the first area, in this case, in order to reduce the query load of the third network device, the first network device can first filter out the specific terminals according to the first information, and further query the third network device only for the location information of the specific terminal.

[0098] As an example, the query terminal list may include terminals determined according to the second terminal list and the first information. That is, only specific terminals in the second terminal list may be screened for location query. In other words, the query terminal list includes the intersection of the second terminal list and at least one specific terminal included in the first information.

[0099] As another example, the query terminal list includes terminals determined according to all terminal lists received in S205 in combination with the first information. For example, the query terminal list includes the intersection of the first terminal list and at least one specific terminal included in the first information. For another example, the query terminal list includes the intersection of the union of the first terminal list and the second terminal list and at least one specific terminal included in the first information, that is, the query terminal list includes the specific terminals in the first terminal list and the specific terminals in the second terminal list.

[0100] In some embodiments, the query terminal list may also include one or more terminal identifiers, such as SUPI, or GPSI, etc., but the present application is not limited thereto.

[0101] Optionally, in some embodiments, the method 200 further includes:

[0102] S207: The first network device receives the location message of the terminal in the query terminal list replied by the third network device.

[0103] For example, the third network device may determine the specific location of the terminal in the query terminal list based on a location service (LCS) mechanism.

[0104] Furthermore, in some embodiments, the method 200 further includes:

[0105] S208: The first network device determines a target terminal list.

[0106] In some embodiments of the present application, the first network device may determine the target terminal list according to the terminal list included in the third message.

[0107] Case 1: the third message may include only the first terminal list.

[0108] In this case, the first network device may determine the target terminal list according to the first terminal list.

[0109] As an example, the first terminal list is determined as the target terminal list.

[0110] As another example, the target terminal list is determined according to the location information of the terminals in the first terminal list and the first area information. For example, the target terminal list includes the terminals in the first terminal list that are in the first area. The location information of the terminals in the first terminal list may be determined in S206.

[0111] As another example, the target terminal list is determined according to the location information of the terminals in the first terminal list, the first area information and the query authority of the query device. For example, the target terminal list includes at least one terminal in the first terminal list that is in the first area and for which the query device has query authority.

[0112] The location information of the terminals in the first terminal list may be determined in S206.

[0113] Case 2: the third message includes the first terminal list and the second terminal list.

[0114] In this case, the first network device may determine a target terminal list according to the first terminal list and the second terminal list.

[0115] As an example, the first terminal list and the second terminal list are determined as the target terminal list.

[0116] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the second terminal list, and the first area information. For example, the target terminal list includes the terminals in the first terminal list that are in the first area and the terminals in the second terminal list that are in the first area.

[0117] As another example, the target terminal list is determined according to the first terminal list and the second terminal list, the location information of the terminals in the first terminal list and the second terminal list, and the first area information. For example, the target terminal list includes the terminals in the first terminal list that are in the first area and the terminals in the second terminal list that are in the first area.

[0118] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the second terminal list, the first area information, and the query authority of the query device. For example, the target terminal list includes the terminals in the first terminal list that are in the first area and for which the query device has query authority, and the terminals in the second terminal list that are in the first area and for which the query device has query authority.

[0119] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the first terminal list and the second terminal list, combined with the first area information and the query authority of the query device. For example, the target terminal list includes terminals in the first terminal list that are in the first area and for which the query device has query authority, and terminals in the second terminal list that are in the first area and for which the query device has query authority.

[0120] In some other embodiments of the present application, the first network device may determine the target terminal list according to the terminal list included in the third message and the first information.

[0121] Case 1: the third message may include only the first terminal list.

[0122] In this case, the first network device may determine a target terminal list according to the first terminal list and the first information.

[0123] As an example, the target terminal list may be the intersection of the first terminal list and at least one specific terminal in the first information. That is, the target terminal list includes at least one first-category terminal, wherein the first-category terminal is included in the first terminal list and is included in the at least one specific terminal in the first information.

[0124] As another example, the first network device may determine the target terminal list based on the first terminal list, the location information of the terminals in the first terminal list and the first information. For example, the target terminal list includes terminals in the first area in the intersection of the first terminal list and at least one specific terminal in the first information.

[0125] As another example, the first network device may determine the target terminal list based on the first terminal list, the location information of the terminals in the first terminal list, the first information, and the query authority of the query device. For example, the target terminal list includes terminals in the intersection of the first terminal list and at least one specific terminal in the first information that are in the first area and for which the query device has query authority.

[0126] Case 2: The first terminal list and the second terminal list in the third message

[0127] In this case, the first network device may determine a target terminal list according to the first terminal list and the second terminal list in combination with the first information.

[0128] As an example, an intersection of the first terminal list, the second terminal list and at least one terminal in the first information is determined as the target terminal list.

[0129] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the second terminal list, and the first area information and the first information. For example, the target terminal list includes at least one terminal in the first area in the intersection of the first terminal list, the second terminal list, and at least one terminal in the first information.

[0130] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the first terminal list and the second terminal list, combined with the first area information and the first information. For example, the target terminal list includes at least one terminal in the first area that is in the intersection of the first terminal list and the second terminal list and at least one terminal in the first information.

[0131] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the second terminal list, the first area information, and the query authority of the query device. For example, the target terminal list includes at least one terminal in the intersection of the first terminal list, the second terminal list, and at least one terminal in the first information, which is in the first area and for which the query device has query authority.

[0132] As another example, the target terminal list is determined based on the first terminal list and the second terminal list, the location information of the terminals in the first terminal list and the second terminal list, combined with the first area information and the query authority of the query device. For example, the target terminal list includes at least one terminal in the intersection of the first terminal list and the second terminal list and at least one terminal in the first information, which is in the first area and for which the query device has query authority.

[0133] In summary, the first network device can determine the target terminal list according to the first terminal list, the second terminal list, the location information of the terminals in the query terminal list, the first information and at least one of the query authority of the query device.

[0134] The terminals in the target terminal list meet at least one of the following conditions:

[0135] The terminal is included in the first terminal list;

[0136] The terminal is included in the second terminal list;

[0137] The terminal is included in at least one specific terminal in the first information;

[0138] The terminal is in the first area;

[0139] The query device has query authority for the terminal.

[0140] Furthermore, in some embodiments, the method 200 further includes:

[0141] S209: The first network device sends the target terminal list to the query device.

[0142] Therefore, when the first network device receives a query request from the query device for terminals in a specific area, it can query the terminal list in the specific area through the second network device, and further report the terminal list in the specific area to the query device, thereby realizing the query requirement for terminals in the specific area.

[0143] Combination Figure 4 , taking the first network device as a UAVF entity, or UAV support function entity, the second network device as an AMF entity, the third network device as a GMLC entity, and the query device as UTM, USS or TPAE as an example, the query method of UAV in a specific area is explained.

[0144] Step 11: The UAVF in the 3GPP network obtains UAV information.

[0145] For example, the UAV information is obtained from the AMF during the process of the UAV registering to the 3GPP network, or from the UTM or USS. It can also be that after the UAV registers to the 3GPP network, the AMF or UTM or USS actively updates the UAV information to the UAVF. Figure 4 As shown in step 11a or step 11b in .

[0146] Optionally, the UAV information includes at least one of the following information:

[0147] The UAV identifier may be, for example, an identifier assigned by the 3GPP network to the UAV, such as SUPI or GPSI, or an identifier of the UAV outside the 3GPP network, such as an identifier of the UAV in an aviation management system, or a mapping relationship between these identifiers;

[0148] The UTM and / or USS and / or TPAE information corresponding to the UAV may be, for example, the identification or address information of the UTM and / or USS and / or TPAE to which the UAV belongs / registers, or the identification or address information of the UTM and / or USS and / or TPAE that has the authority to manage or query the UAV.

[0149] Step 12: UTM or USS or TPAE sends a query request to UAVF, carrying the first area information to be queried. For example, UTM / USS / TPAE can directly perform signaling interaction with UAVF, or perform signaling interaction through NEF.

[0150] Step 13: The UAVF determines second area information, where the second area information is area information defined by the 3GPP network.

[0151] For example, if the first area information received in step 1 is the area information defined by 3GPP, such as a cell identifier, a TA (Tracking area) identifier, the UAVF directly uses the received first area information as the second area information.

[0152] For another example, if the first area information in step 1 is information that can be mapped to one or more 3GPP defined areas, for example, a coarse-grained area identifier such as a country or a city can generally be mapped to the 3GPP defined area information, the UAVF maps the received first area to the second area information.

[0153] For another example, if the first area information of the query received in step 1 cannot be mapped to the area information defined by 3GPP, such as a finer-grained area identifier, a specific airport, a block, or an area bounded by a road, or an area range identified by longitude and latitude. UAVF maps the received first area to a second area including the query area, for example, the first area is a block, and the mapped second area is a TA including the block, wherein the TA range is larger than the block range.

[0154] Step 14: UAVF sends a query request to AMF, carrying the second area information to be queried, and instructing AMF to query the UE list in the area.

[0155] Step 15: AMF feeds back the UE list information in the area to UAVF.

[0156] Optionally, it also includes UE list information that may be located in the area, such as UE list information that is in idle state and the UE registration area includes the second area. The UE list information includes one or more UE identifiers, and the UE identifier can be an identifier such as SUPI, GPSI, etc.

[0157] In step 16, the UAVF determines a list of UEs that need further location query, which may be, for example, a list of UEs that may be located in the area and received in step 15, or a list of UEs that are identified as UAVs by comparing this list with the UAV information in step 11. The UE list includes, for example, all the UE lists received in step 15, or a list of UEs that are identified as UAVs by comparing this list with the UAV information in step 11.

[0158] Optionally, the UE list for location query includes one or more UE identifiers, and the UE identifier may be an identifier such as SUPI, GPSI, etc. The UAVF may send the UE list for location query to the GMLC for location query, or may send each UE identifier in all received lists to the GMLC for query.

[0159] Step 17: UAVF obtains the specific location of the queried UE from GMLC.

[0160] It should be understood that steps 16 and 27 are optional steps.

[0161] Step 18: The UAVF determines the UAV list that needs feedback.

[0162] For example, the UAV list fed back is determined based on at least one of the following:

[0163] Compare the UE identification received in step 15 with the UAV information in step 11 to identify the UAV;

[0164] Compare the UE identification received in step 15 with the UAV information in step 11 to identify the UAV that the querying party has the authority to query;

[0165] Compare the UE and location information obtained in step 17 with the first area information and the UAV information in step 11 to identify the UAV in the first area information;

[0166] The UE and location information obtained in step 17 are compared with the first area information and the UAV information in step 11 to identify the UAV in the first area information that the querying party has the authority to query.

[0167] Step 29: UAVF feeds back the UAV list to the UTM / USS / TAPE of the inquiring party.

[0168] When the UE identity or UAV identity in the above steps 11, 15, 16, and 18 needs to be converted to each other and the UAVF itself cannot convert, the UAVF can query other network elements such as UDM to convert the identity.

[0169] Figure 5FIG. 3 is a schematic interactive diagram of a wireless communication method 300 according to another embodiment of the present application. Figure 5 As shown, the method 300 may include at least part of the following:

[0170] S302: A first network device receives a first message sent by a query device, where the first message includes first area information, and the first message is used to request a query for terminals in a first area indicated by the first area information.

[0171] Optionally, in an embodiment of the present application, the first network device may be an existing network device, for example, a NEF entity, that is, the function of the first network device may be added to the existing network device, or a new functional entity may be added to interface with a third-party application server and transmit information between the core network node and the third-party application. This application does not limit this.

[0172] Optionally, the first network device and the query device may directly perform signaling interaction, or may perform signaling interaction through other devices. For example, if the first network device is not an NEF entity, the first network device and the query device may perform signaling interaction through an NEF entity. Specifically, the query device may send the first area information to the NEF entity, and the first NEF entity forwards the first area information to the first network device.

[0173] Optionally, the first message can be used to request a query for a list of terminals in a specific area, where the terminals can be ordinary terminals, such as the various terminal types described in the previous embodiments, or other types of terminals, for example, mechanical equipment, such as drones, etc. The present application is not limited to this.

[0174] As a specific example, the first message may be used to request a query on a specific terminal in a specific area, and the specific terminal may be, for example, a mechanical device such as a drone.

[0175] Optionally, the query device may be any device having authority to query the location of the terminal, such as UTM, USS or TPAE, etc., but the present application is not limited thereto.

[0176] Optionally, in some embodiments, the method 300 further includes:

[0177] S303: The first network device sends a fifth message to a third network device, where the fifth message includes the first area information and is used to request a query of terminals in the first area.

[0178] Optionally, the third network device may be a network device capable of querying the location information of the terminal, such as GMLC, etc., but the present application is not limited thereto.

[0179] S304: The third network device determines second area information according to the first area information, where the second area information may be area information defined by a 3GPP network.

[0180] As an example, if the first area information is area information defined by a 3GPP network, the first area information is determined as the second area information. For example, the first area information may be a cell identifier or a tracking area (TA) identifier, in which case the first area information may be determined as the second area information.

[0181] As another example, if the first area information is not area information defined by the 3GPP network, and can be mapped to the area information defined by the 3GPP network, the area information defined by the 3GPP network mapped by the first area information is used as the second area information. For example, the first area information is a coarse-grained area identifier such as a country or a city. In this case, the first area information can be mapped to one or more area information defined by 3GPP. Therefore, the one or more area information defined by 3GPP to which the first area information is mapped can be determined as the second area information.

[0182] As another example, if the first area information is not the area information defined by the 3GPP network and cannot be mapped to the area information defined by the 3GPP network, in this case, the area information defined by the 3GPP network including the first area can be determined as the information of the second area. For example, the first area information is a finer-grained area identifier, a specific airport, a block, or an area bounded by a certain road, or an area range identified by longitude and latitude. In this case, the first area can be mapped to a second area including the first area, for example, the first area is a block, and the mapped second area is, for example, a TA including the block, wherein the range of the TA is larger than the range of the block.

[0183] Furthermore, in some embodiments, the method 300 may also include:

[0184] S305: The third network device sends a sixth message to the second network device, where the sixth message includes the second area information, and the sixth message is used to request to query terminals in the second area indicated by the second area information.

[0185] Optionally, the second network device may be a network device having a terminal list for querying a certain area, such as an AMF entity.

[0186] In S306, the third network device receives a seventh message replied by the second network device, wherein the seventh message includes a fourth terminal list, and the fourth terminal list includes terminals in the second area.

[0187] In some embodiments, the fourth terminal list may include one or more terminal identifiers, such as SUPI, or GPSI, etc., but the present application is not limited thereto.

[0188] Optionally, in some embodiments, the seventh message may further include a fifth terminal list, the fifth terminal list including terminals that may be in the second area. For example, the terminals that may be in the second area include terminals that are in an idle state and whose registration area intersects with the second area.

[0189] In some embodiments, the fifth terminal list may also include one or more terminal identifiers, such as SUPI, or GPSI, etc., but the present application is not limited thereto.

[0190] Optionally, in some embodiments, the third network device may determine the fourth terminal list as the third terminal list fed back to the first network device.

[0191] In some scenarios, if the first area information and the second area information indicate the same area, or the second area information is mapped from the first area information, in this case, the third network device may determine the fourth terminal list as the third terminal list.

[0192] Optionally, in some other embodiments, the method 300 further includes:

[0193] S307: The third network device determines a specific position in the terminal list included in the seventh message.

[0194] Optionally, the third network device may determine the specific location of the terminal based on the LCS mechanism.

[0195] Optionally, the third network device may only determine the specific positions of the terminals in the fifth terminal list, or may also determine the specific positions of the terminals in the fourth terminal list and the fifth terminal list.

[0196] Furthermore, the third network device may determine the third terminal list according to the determined specific location of the terminal in combination with the first area information.

[0197] As an example, the third network device determines the third terminal list according to the fourth terminal list, the fifth terminal list, and the location information of the terminals in the fifth terminal list, in combination with the first area information.

[0198] For example, the third terminal list includes the terminals in the fourth terminal list that are within the first area, and the terminals in the first area are determined according to the location information of the terminals in the fifth terminal list.

[0199] As another example, the third network device determines the third terminal list according to the fourth terminal list and the location information of the terminals in the fourth terminal list, the fifth terminal list and the location information of the terminals in the fifth terminal list, and the first area information.

[0200] For example, the third terminal list includes terminals located in the first area determined according to location information of terminals in the fourth terminal list, and terminals located in the first area determined according to location information of terminals in the fifth terminal list.

[0201] The location information of the terminals in the fourth terminal list and the location information of the terminals in the fifth terminal list may be determined in S307.

[0202] Further, in S308, the third terminal list is sent to the first network device.

[0203] Optionally, in some other embodiments, the method 300 further includes:

[0204] S309: The first network device determines a target terminal list according to the third terminal list.

[0205] As an example, the third terminal list is used as the target terminal list.

[0206] In some other embodiments, the first network device determines a target terminal list based on the third terminal list in combination with the first information. For example, the target terminal list includes an intersection of the third terminal list and at least one specific terminal in the first information.

[0207] In some further embodiments, the first network device determines the target terminal list according to the third terminal list in combination with the first information and the query authority of the query device.

[0208] For example, the target terminal list includes terminals for which the query device has query authority in the intersection of the third terminal list and at least one specific terminal in the first information.

[0209] Combination Figure 6 , taking the first network device as a UAVF entity, or UAVF entity, the second network device as an AMF entity, the third network device as a GMLC entity, and the query device as UTM, USS or TPAE as an example, the query method of UAV in a specific area is explained.

[0210] Steps 21-22 and Figure 4 Steps 11 and 12 in the illustrated embodiment are similar and are not described here in detail.

[0211] Step 23: UAVF sends a query request to GMLC, carrying the first area information to be queried, and instructs GMLC to query the UE list in the area.

[0212] Step 24: GMLC determines second area information, where the second area information is area information defined by the 3GPP network.

[0213] If the first area information received in step 23 is area information defined by 3GPP, such as a cell identifier, a TA (Tracking area) identifier, or information that can be mapped to one or more areas defined by 3GPP, such as a coarse-grained area identifier such as a country or a city, which can generally be mapped to the area information defined by 3GPP, the GMLC directly uses the received first area information as the second area information or maps the received first area information to the second area information.

[0214] If the first area information received in the query in step 23 cannot be mapped to the area information defined by 3GPP, such as a finer-grained area identifier, a specific airport, a block, or an area bounded by a road, or an area range identified by longitude and latitude, GMLC maps the received first area to a second area including the area. For example, if the first area is a block, the mapped second area is a TA including the block (the TA range is larger than the block range).

[0215] Step 25, GMLC sends a query request to AMF, carrying the second area information to be queried, and instructs AMF to query the UE list in the area.

[0216] Step 26: AMF feeds back the UE list information in the area to GMLC.

[0217] Optionally, it also includes UE list information that may be located in the area, such as UE list information that is in idle state and the UE registration area includes the second area. The UE list information includes one or more UE identifiers, and the UE identifier can be an identifier such as SUPI, GPSI, etc.

[0218] In step 27, the GMLC uses the LCS positioning mechanism to determine the specific location of the UE, for example, determining the specific location of the UE in the list of UEs that may be located in the second area received in step 26 or the list of all UEs received in step 26.

[0219] In step 28, the GMLC determines the UE list located in the first area based on the UE list obtained in step 26 and the UE location determined in step 27, and feeds it back to the UAVF.

[0220] For example, if the second area is the same as the first area, or is directly mapped from the first area, the UE list obtained from the AMF in step 26 is used as the UE list of the first area. If step 26 also includes UE list information that may be located in the area, the UE list located in the first area is determined by comparing the specific location of the UE that may be located in the second area obtained in step 27 with the first area information. If the scope of the second area is larger than the scope of the first area, the UE list located in the first area is determined by comparing the specific locations of all UEs in the second area obtained in step 27 with the first area information.

[0221] In step 29, the UAVF compares the UE list received in step 28 with the UAV information in step 21 to identify the UAVs therein, or identifies the UAVs that the querying party has the authority to query.

[0222] Step 30: UAVF feeds back the UAV list to the UTM / USS / TAPE of the inquiring party.

[0223] When the UE identity or UAV identity in the above steps needs to be converted to each other and the GMLC or UAVF itself cannot perform the conversion, the GMLC or UAVF can query other network elements such as UDM to convert the identity.

[0224] Therefore, when the first network device receives a query request from the query device for terminals in a specific area, it can query the terminal list in the specific area through the second network device, and further report the terminal list in the specific area to the query device, thereby realizing the query requirement for terminals in the specific area.
