[0187] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant knowledge is first introduced as follows.

[0188] 1. Prohibited sending areas

[0189] The restrictions for prohibited areas / no-transmit zones are as follows:

[0190] 1) 703-733MHz: Protection of radio telescopes and digital terrestrial television receivers.

[0191] Drones operating in the 703-733MHz band should not transmit data when they are less than 30 meters above the ground to avoid interfering with digital terrestrial television receivers.

[0192] Radio telescopes operating in the 1400-1427 MHz band are prohibited from flying drones in the 703-718 MHz band.

[0193] 2)832-837MHz: Protects radio telescopes.

[0194] Radio telescopes operating at 1660-1670 MHz are in a restricted zone for drones operating at 832-837 MHz.

[0195] 3)2500-2570MHz / 2570-2620MHz: Protect radio telescopes and radar stations.

[0196] Radio telescopes operating in the 2690-2700MHz band are prohibited from flying drones operating in the 2500-2570MHz or 2570-2620MHz bands.

[0197] Radars operating in the 2700-2900MHz band are in a restricted zone for drones operating in the 2500-2570MHz or 2570-2620MHz band.

[0198] 2. Terms / Nouns Used in This Application

[0199] a) Protected frequencies / restricted frequencies / prohibited frequencies: frequencies that are prohibited for UE to use in prohibited transmission areas, frequencies protected by prohibited transmission areas, frequencies that UE cannot use in prohibited transmission areas, and frequencies that UE cannot send data / signaling / radio signals using in prohibited transmission areas.

[0200] For example, in the requirement "UAVs operating in the 703-733 MHz band should not transmit data when the drone is less than 30 meters above the ground to avoid interference with digital terrestrial television receivers," 703-733 MHz is a protected frequency, restricted frequency, or prohibited frequency. For ease of understanding, this application will refer to this frequency as the protected frequency, restricted frequency, or prohibited frequency, although other terms may also be used.

[0201] b) Non-protected frequency / non-restricted frequency / non-prohibited frequency: A frequency that can be used in a prohibited transmission area, i.e., a UE can use this frequency to send data / signaling / radio signals. For ease of understanding, this application refers to this frequency as non-protected frequency / non-restricted frequency / non-prohibited frequency, although other terms may also be used.

[0202] c) Protected altitude / restricted altitude / prohibited altitude: When the UE is in the prohibited transmission area, if the UE altitude is lower than this altitude, the UE shall comply with the restrictions of the prohibited transmission area.

[0203] For example, in the requirement "UAVs operating in the 703-733 MHz frequency band should not transmit data when the drone is less than 30 meters above the ground to avoid interference with digital terrestrial television receivers," 30 meters is the protected altitude, restricted altitude, or prohibited altitude. For ease of understanding, this application will refer to these altitudes as protected altitudes, restricted altitudes, or prohibited altitudes, although other terms may also be used.

[0204] 3. Related Background Technology

[0205] 1) Non-permitted areas

[0206] The network determines the non-allowed area (e.g., a cell list) and sends it to the UE. If the UE is in the non-allowed area, the Access and Mobility Management Function (AMF) sends a message to the Session Management Function (SMF) that the UE is only reachable for emergency services. The SMF then deactivates the Protocol Data Unit (PDU) session related to non-emergency services. The UE can initiate a periodic registration request.

[0207] 2) Prohibited areas

[0208] The network determines the prohibited area (e.g., cell list) and sends it to the UE. If the UE is located in the prohibited area, the AMF rejects the registration request or service request. The UE cannot initiate a registration request.

[0209] However, regardless of whether it is a non-permitted area or a prohibited area, the UE can use any frequency supported by the cell to send data, and there is no altitude restriction, so it cannot support the requirements of the prohibited area.

[0210] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0212] Step 101: Receive first information sent by a first device or a second device, where the first information is related to a prohibited area.

[0213] It should be noted that the embodiments of the present application can be applied to scenarios supporting no-launch zones, for example, when a terminal enters, is located in, or leaves a no-launch zone. The terminal is an aerial UE, a drone, or an unmanned aerial vehicle (UAV), the first device is a radio access network (RAN) device, and the second device is an access and mobility management function (AMF) device.

[0214] Specifically, the first device or the second device may obtain first information from an operation, administration, and maintenance (OAM) device, wherein the first information is related to the prohibited zone.

[0412] Next, the terminal control method provided in this application will be further described through specific embodiments.

[0413] Embodiment 1: In this embodiment, a RAN node receives first information from an OAM, where the first information is related to a prohibited area.

[0414] Figure 6 This is a schematic diagram of the interaction between RAN and OAM provided in an embodiment of the present application, such as Figure 6 As shown, specifically including:

[0415] Step 601: OAM sends first information to a RAN node. The first information includes a first cell identifier, prohibited area indication information, protection frequency, protection altitude, etc.

[0416] Embodiment 2: In this embodiment, the UE obtains first information, where the first information includes geographical area information related to the prohibited area or cell information including information related to the prohibited area.

[0417] Figure 7 This is one of the interaction diagrams between UE, RAN and AMF provided in the embodiment of the present application, such as Figure 7 As shown, the UE obtains the first information from the RAN or AMF, specifically including:

[0418] Step 701: RAN sends an NG setup request message to AMF, where the NG setup request message includes first information, such as a first cell identifier, prohibited area indication information, protection frequency and protection height, etc.

[0419] Step 702: AMF sends an NG setup reply message to RAN.

[0420] The network may send first information to the UE through the method in box (A), (B) or (C), where the first information is related to the prohibited area.

[0421] Box (A): Step 703, the UE sends a registration request message to the AMF.

[0422] Step 704: The AMF sends a registration reply message to the UE, where the registration reply message includes the first information.

[0423] Block (B): Step 705 , the UE sends an RRC message to the RAN (the RRC message includes a registration request).

[0424] Step 706: RAN sends an N2 message to AMF, where the N2 message includes a registration request.

[0425] In step 707, the AMF sends an N2 message to the RAN. The N2 message includes a registration acceptance, an over-the-air UE indication, and a registration area. Based on the registration area and the cell information received from the OAM, the RAN determines whether the registration area includes a prohibited area. If so, the RAN sends the first message to the UE in step 708.

[0426] Step 708: The RAN sends an RRC message to the UE. The RRC message includes a registration acceptance and the first information.

[0427] Block (C): Step 709 , the RAN node sends a first broadcast message to the UE, where the first broadcast message includes first information.

[0428] In this embodiment, the scenario is that a cell supports multiple frequencies, some of which are protected frequencies in a prohibited area. When a UE enters the cell, the UE should select a non-protected frequency, or the RAN node should configure a non-protected frequency for the UE.

[0429] Figure 8 This is the second schematic diagram of the interaction between UE, RAN and AMF provided in the embodiment of the present application, such as Figure 8 As shown, specifically including:

[0430] Step 801: The UE detects entry into a prohibited area based on a first broadcast message, or a second broadcast message and locally stored first information.

[0431] Step 802: The UE selects a non-protection frequency based on the protection frequency in the first information.

[0432] Step 803: The RAN node sends an RRC message to the UE. The RRC message carries available frequencies, that is, non-protected frequencies.

[0433] Step 804: The UE selects an available frequency or a non-protected frequency.

[0434] Step 805: The RAN node sends an N2 message to the AMF, where the N2 message carries the first information.

[0435] It should be noted that in this scenario, except for steps 801 to 805 above, the behaviors of UE, RAN and AMF are the same as those in the prior art.

[0436] Embodiment 4: In this embodiment, the scenario is that the current altitude of the UE (the altitude from the ground) is higher than the protection altitude, and the UE can use the protection frequency or the non-protection frequency.

[0437] Figure 9 This is the third diagram of the interaction between UE, RAN and AMF provided in the embodiment of the present application, such as Figure 9 As shown, specifically including:

[0438] Step 901: The UE and / or RAN detects that the UE enters a prohibited area, or the UE enters a cell that overlaps with the prohibited area.

[0439] Step 902: The UE determines, based on sensor data and a flight path, that the UE's altitude is greater than a protection altitude during the period the UE stays in the cell.

[0440] Step 903: The UE sends an RRC message to the RAN. The RRC message includes second information. The second information includes sensor data, a current altitude, and second indication information. The second indication information is used to indicate that the current altitude is greater than the protection altitude.

[0441] Step 904: The RAN sends an N2 message to the AMF, where the N2 message includes the second information.

[0442] Step 905: The UE sends a NAS message to the AMF, where the NAS message includes the second information.

[0443] Embodiment 5: In the embodiment of the present application, the UE enters a prohibited area, the cell where the UE is located only supports protection frequencies, and the height of the UE in the prohibited area or in the cell where the UE is located is lower than the protection height.

[0444] Figure 10 This is the fourth diagram of the interaction between UE, RAN and AMF provided in the embodiment of the present application, such as Figure 10 As shown, specifically including:

[0445] Step 1001: The UE and / or the RAN node detects that the UE enters a prohibited area, or that the UE enters a cell that overlaps with the prohibited area.

[0446] It should be noted that if the UE is in an idle state, only the UE can detect that the UE has entered a prohibited area or a cell that includes the first information. In this case, as long as the UE is in the prohibited area or the cell it is in is a cell that includes the first information, the UE does not respond to paging and does not send data, signaling, or wireless signals. The UE sends a service request, registration request, or responds to paging until it detects that it has left the prohibited area or entered a cell that does not include the first information.

[0447] If the UE is in a connected state, both the UE and the RAN can detect that the UE has entered a prohibited area, and then proceed to steps 1002 to 1007.

[0448] Step 1002: The RAN starts a first timer. If the first timer times out or reaches a specific threshold, or if the RAN does not receive any message from the UE, the RAN determines that the UE's frequency and altitude are restricted by a restricted area, and the UE cannot send data, signaling, or radio signals. The RAN may release the RRC connection.

[0449] Step 1003: The RAN node sends an N2 message to the AMF. The N2 message includes first information, such as an indication that the UE has entered a restricted area. The AMF may send a first event notification message to the SMF, a Network Exposure Function (NEF), or a Policy Control Function (PCF). The event notification message carries the first information.

[0450] Step 1004: The AMF starts a second timer / second timer. If the second timer times out or reaches a specific threshold, and the AMF does not receive any message from the UE, the AMF determines that the UE's frequency and altitude are restricted by the restricted area, and the UE cannot send data, signaling, or radio signals. The AMF may release the N2 connection. The AMF stores in the UE context that the UE is unreachable in the restricted area. The AMF may send a second event notification message to the SMF, NEF, or PCF. The second event notification message carries second information, such as that the UE is unreachable due to being in the restricted area.

[0451] Step 1005: The UE and / or RAN detects that the UE leaves the prohibited area or enters a cell that does not include the first information.

[0452] Step 1006: The UE sends a registration request or service request to the AMF.

[0453] Step 1007: The RAN sends an N2 message to the AMF, where the N2 message includes second information, such as an indication that the UE moves out of the prohibited area.

[0454] In this embodiment, the cell only supports the protection frequency. The UE's altitude may be greater than or less than the protection altitude during its stay in the cell. When the UE's altitude is greater than the protection altitude, the UE may use the cell's frequency, i.e., the protection frequency, to send data.

[0455] If the UE is in an idle state, as long as the UE is in a prohibited area or the cell in which the UE is located includes the first information, the UE does not respond to paging and does not send data, signaling, or wireless signals. Until the UE detects that it has left the prohibited area or entered a cell that does not include the first information, the UE sends a service request, a registration request, or responds to the paging.

[0456] For UE in connected state, the process to support the above scenario is as follows Figure 11 As shown, Figure 11 This is a schematic diagram of the interaction between UE, RAN, AMF and SMF / PCF / NEF / NWDAF provided in an embodiment of the present application, such as Figure 11 As shown, specifically including:

[0457] Step 1101: The UE and the RAN node detect that the UE has entered a prohibited area, or that the cell entered by the UE includes first information. It should be noted that the UE may also start a timer.

[0458] Step 1102: The RAN node starts a first timer / a first timer.

[0459] Step 1103: The RAN node sends an N2 message to the AMF. The N2 message includes first information, such as an indication of entering a prohibited area, or a cell identifier and a prohibited area indication.

[0460] Step 1103a: AMF sends a first event notification message to SMF / NEF / PCF / NWDAF, where the first event notification message includes first information.

[0461] Step 1104: The AMF starts the second timer / second timer.

[0462] Step 1105: The UE determines second information. The UE determines second information based on at least one of the flight path, moving direction, moving speed, current altitude, and protected altitude, such as an indication of entering a prohibited area, a time when the UE can send or communicate, a time when the UE cannot send or communicate, and an indication that the UE can send or communicate.

[0463] Step 1106: When the UE detects that its altitude is greater than the protection altitude, the UE stops the timer.

[0464] Step 1107a: The UE sends an RRC message to the RAN, where the RRC message includes the second information.

[0465] Step 1107b: The UE sends a NAS message to the AMF, where the NAS message includes the second information.

[0466] Step 1108: The RAN stops the first timer / the first timer.

[0467] Step 1109: The RAN sends an N2 message to the AMF, where the N2 message includes the second information.

[0468] Step 1110: The AMF receives the message of step 1107b or step 1109 and stops the second timer / first timer.

[0469] Step 1111, AMF sends a first event notification message to SMF, NEF, PCF or NWDAF, and the first event notification message includes the second information. Among them, SMF can decide the time to send the downlink message according to the time when the UE can send or communicate, and SMF can notify UPF to cache downlink data during the time when the UE cannot send or communicate, or notify UPF to cache downlink data. NEF can send the second information of the UE to the application function (AF). PCF can determine the policy and charging control (PCC) rule based on the second information of the UE. For example, when the UE cannot send or communicate, the PCF sets the rate of the PCC rule to 0, and the RAN and UPF discard the UE's data according to the rate; when the UE can send or communicate, the PCF restores the rate of the PCC rule to the rate that the UE can use. NWDAF determines the analysis results related to the UE in the prohibited area or the analysis results of the UE's movement trajectory based on the second information of the UE.

Figure 12 As shown, the terminal includes a memory 1220, a transceiver 1200 and a processor 1210; wherein the processor 1210 and the memory 1220 may also be physically arranged separately.
