[0158] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0159] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0160] 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.

[0161] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0162] 1) Prohibited sending area

[0163] The no-transmit zones and frequency restrictions are as follows:

[0164] 703-733MHz: Protection of radio telescopes and digital terrestrial television receivers.

[0165] 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.

[0166] Radio telescopes operating in the 1400-1427 MHz band are prohibited from flying drones in the 703-718 MHz band.

[0167] 832-837MHz: Protects radio telescopes.

[0168] Radio telescopes operating at 1660-1670 MHz are in a restricted zone for drones operating at 832-837 MHz.

[0169] 2500-2570MHz / 2570-2620MHz: Protects radio telescopes and radar stations.

[0170] Radio telescopes operating in the 2690-2700MHz band are prohibited from flying drones operating in the 2500-2570MHz or 2570-2620MHz bands.

[0171] Radars operating in the 2700-2900MHz band are in a restricted zone for drones operating in the 2500-2570MHz or 2570-2620MHz band.

[0172] 2) Protected frequency / restricted frequency / prohibited frequency

[0173] The prohibited sending area prohibits the terminal from using the frequency, or the prohibited sending area protects the frequency, or the terminal cannot use the frequency in the prohibited sending area, or the terminal cannot send data / signaling / wireless signals using these frequencies in the prohibited sending area. For example, in the requirement "UAVs operating at 703-733MHz should not send data when the altitude is less than 30 meters from the ground to avoid interfering with digital terrestrial television receivers.", 703-733MHz is a protected / restricted frequency. For ease of understanding, this application refers to this frequency as a protected frequency / restricted frequency / prohibited frequency, and other terms may also be used.

[0174] 3) Non-protected frequency / non-restricted frequency / non-prohibited frequency

[0175] A frequency that can be used in a prohibited transmission zone, i.e., a terminal can use this frequency to send data / signaling / wireless signals. For ease of understanding, this application refers to this frequency as a non-protected frequency / non-restricted frequency / non-prohibited frequency, and other terms may also be used.

[0176] 4) Protected height / restricted height / prohibited height

[0177] When a terminal is in a prohibited transmission zone and its altitude is below that altitude, it must comply with the prohibited transmission zone restrictions. For example, in the requirement "UAVs operating in the 703-733MHz band should not transmit data when below 30 meters above the ground to avoid interference with digital terrestrial television receivers," 30 meters is the protected altitude / restricted altitude. For ease of understanding, this application will refer to this altitude as the protected altitude / restricted altitude, but other terms may also be used.

[0178] 5) Non-permitted areas

[0179] The network determines the non-allowed area (e.g., a cell list) and sends it to the terminal. If the terminal is located in the non-allowed area, the Access and Mobility Management Function (AMF) sends a message to the Session Management Function (SMF) that the terminal is only reachable for emergency services. The SMF deactivates the Packet Data Unit (PDU) session related to non-emergency services. The terminal can initiate a periodic registration request.

[0180] 6) Prohibited areas

[0181] The network determines the prohibited area (such as a cell list) and sends it to the terminal. If the terminal is located in the prohibited area, the AMF rejects the registration request or service request, and the terminal cannot initiate a registration request.

[0182] In summary, regardless of whether the area is not permitted or prohibited, a terminal can transmit data using any frequency supported by the cell, with no altitude restrictions. In real-world scenarios, even if a terminal does not enter the area, interference can occur when the terminal approaches it. Existing technologies cannot address the frequency interference problem caused by a terminal approaching a prohibited transmission area.

[0183] Figure 1 The data collection method provided in this embodiment is a flow chart of the present invention, which is applied to a terminal, such as Figure 1 As shown, the method includes the following steps:

[0184] Step 100: Receive relevant information about a second cell adjacent to a first cell. The relevant information about the second cell adjacent to the first cell includes at least one of the following:

[0185] identification information of the second cell;

[0186] Prohibition of sending instruction information;

[0187] Protection frequency;

[0188] Non-protected frequencies;

[0189] Protection height;

[0190] Prohibited sending areas;

[0191] First indication information: The first indication information is used to instruct the terminal to stop sending data and / or receiving data in the second cell.

[0192] Specifically, in an embodiment of the present application, a terminal first receives relevant information about a second cell adjacent to a first cell. Optionally, the first cell is the cell in which the terminal resides; the second cell is a neighboring cell of the first cell; and the prohibition indication information in the relevant information about the second cell is used to indicate whether the area covered by the second cell overlaps with the geographical area of the prohibition zone. Optionally, because the first cell in which the terminal resides is adjacent to the second cell, if the prohibition indication information indicates that the area covered by the second cell overlaps with the geographical area of the prohibition zone, it indicates that the terminal is approaching the prohibition zone.

[0193] Optionally, the protection frequency in the relevant information of the second cell is used to indicate the frequency that the terminal is prohibited from using in the prohibited area; the non-protected frequency is used to indicate the frequency that the terminal is allowed to use in the prohibited area; the protection altitude is used to indicate the flight altitude at which the terminal is prohibited from transmitting data in the prohibited area; the prohibited transmission area is used to indicate the geographical area information in which the terminal is prohibited from transmitting data in the prohibited area; and the first indication information is used to instruct the terminal to stop sending and / or receiving data in the second cell. In other words, the terminal can not only determine whether it is approaching the prohibited area based on the relevant information of the second cell, but also determine specific information such as the protection altitude and protection frequency of the prohibited area that overlaps with the coverage area of the second cell based on the relevant information of the second cell, thereby providing sufficient and effective information for resolving the frequency interference problem caused when the terminal approaches the prohibited area.

[0194] Step 101: Perform a target action based on relevant information of a second cell adjacent to a first cell. The target action includes at least one of the following:

[0195] Select non-protected frequency;

[0196] Stop sending and / or receiving data;

[0197] The terminal information related to the second cell, the MICO mode related parameters and / or the DRX parameters are sent to the first device and / or the second device.

[0198] Specifically, when the terminal determines that it is approaching a prohibited area based on relevant information of the second cell and obtains specific information such as the protection height and protection frequency of the prohibited area overlapping with the coverage area of the second cell, the terminal can select a non-protection frequency to send and receive data to solve the frequency interference problem generated when the terminal is close to the prohibited area; the terminal can also directly stop sending and / or receiving data to solve the frequency interference problem generated when the terminal is close to the prohibited area; the terminal can also send terminal information related to the second cell, MICO mode related parameters and / or DRX parameters to the access network device or the core network device, thereby avoiding interference problems caused by data transmission when the terminal is close to the prohibited area.

[0199] According to the method of the above embodiment, after receiving the relevant information of the second cell, the terminal can determine that the terminal is close to the prohibited area and obtain specific information such as the protection height and protection frequency of the prohibited area overlapping with the coverage area of the second cell based on the relevant information of the second cell. Then, it can select a non-protected frequency, stop sending and / or receiving data, send the terminal information related to the second cell, MICO mode related parameters and / or DRX parameters to the first device and / or the second device, etc., thereby effectively solving the interference problem caused by the terminal performing data transmission when it is close to the prohibited area, reducing network interference and improving network quality.

[0200] Optionally, receiving relevant information about a second cell adjacent to the first cell includes:

[0201] Receive a broadcast message and / or signaling sent by the first device or the second device; the broadcast message and / or signaling carries relevant information of a second cell adjacent to the first cell.

[0202] Specifically, in an embodiment of the present application, the terminal can obtain relevant information about the second cell not only from the first device, but also from the second device. The terminal can obtain relevant information about the second cell through a broadcast message, or through signaling. Optionally, the first device is an access network device, and the second device is a core network device; the signaling can be Radio Resource Control (RRC) signaling, or registration acceptance-related signaling, or other signaling. No specific restrictions are made in the embodiment of the present application, thereby enabling the terminal to flexibly obtain relevant information about the second cell in a variety of ways.

[0203] According to the method of the above embodiment, the terminal obtains relevant information of the second cell by receiving broadcast messages and / or signaling sent by the first device or the second device, thereby accurately and efficiently obtaining relevant information of the second cell in multiple ways, effectively improving the flexibility of the terminal in obtaining relevant information of the second cell.

[0204] Optionally, when a target condition is met, a target action is performed according to relevant information of a second cell adjacent to the first cell; the target condition includes at least one of the following:

[0205] The signal strength of the second cell is measured to be greater than a preset strength;

[0206] Entering the second cell after determining the preset time period;

[0207] determining that the distance to the second cell is less than a preset distance;

[0208] The terminal is an airborne terminal and its current altitude is lower than the protection altitude;

[0209] The terminal resides in the first cell.

[0210] Specifically, in an embodiment of the present application, when the terminal monitors that the signal strength of the second cell is greater than a preset strength, and / or when the terminal determines that it enters the second cell after a preset time period, and / or when the terminal determines that the distance to the second cell is less than a preset distance, and / or when the terminal is an airborne terminal and the current altitude is less than the protection altitude, and / or when the terminal resides in the first cell, the terminal performs a target action based on the relevant information of the second cell to resolve the interference problem caused by the terminal performing data transmission when approaching the prohibited area. That is, the terminal determines whether the terminal is approaching the prohibited area in a more comprehensive, accurate and effective manner by judging the signal strength of the second cell, the time of entering the second cell, the distance between the terminal and the second cell, the altitude of the terminal and other information in multiple dimensions, thereby more effectively resolving the interference problem caused by the terminal performing data transmission when approaching the prohibited area.

[0211] Optionally, the terminal information related to the second cell includes at least one of the following:

[0212] Time of entry into the second cell;

[0213] Time to move out of the second cell;

[0214] whether to stop sending and / or receiving data in the second cell;

[0215] the time period during which the data was sent and / or received;

[0216] The period of time during which the sending and / or receiving of data ceases;

[0217] Whether it is affected by the prohibited sending area.

[0218] Specifically, in an embodiment of the present application, when the terminal determines that the terminal is close to the prohibited area based on the relevant information of the second cell and obtains specific information such as the protection height and protection frequency of the prohibited area overlapping with the coverage area of the second cell, the terminal can send the terminal information related to the second cell to the access network device or the core network device. Optionally, the terminal information related to the second cell includes at least one of the following: the time of entering the second cell, the time of moving out of the second cell, whether the second cell stops sending and / or receiving data, the time period for sending and / or receiving data, the time period for stopping sending and / or receiving data, and whether it is affected by the prohibited area. After receiving the terminal information related to the second cell sent by the terminal, the access network device or the core network device can also determine the MICO mode parameters or DRX parameters based on the received terminal information related to the second cell, thereby avoiding interference problems caused by operations such as paging the terminal when the terminal approaches or enters the prohibited area.

[0219] Optionally, before receiving relevant information of a second cell adjacent to the first cell, the method further includes:

[0220] receiving a measurement request message sent by the first device;

[0221] Perform measurement based on the measurement request message, and send the measurement result to the first device or perform the target action; the measurement request message includes at least one of the following:

[0222] an identifier of a second cell adjacent to the first cell;

[0223] a central position of a second cell adjacent to the first cell;

[0224] Distance threshold; the distance threshold is used to indicate that the distance between the terminal and the center location is less than the distance threshold, and the distance is reported;

[0225] Signal strength threshold; the signal strength threshold is used to indicate that when the signal strength of the cell corresponding to the second cell identifier measured by the terminal is greater than the signal strength threshold, the signal strength is reported;

[0226] Altitude threshold: When the terminal is an airborne terminal, the altitude threshold is used to indicate that the current altitude of the terminal is less than the altitude threshold and to report the altitude.

[0227] Specifically, in an embodiment of the present application, the access network device may send a measurement request message to the terminal to request the terminal to measure the distance information from the second cell, the height information of the terminal, and the signal strength information of the second cell. After obtaining the measurement result corresponding to the measurement information, the access network device can accurately determine the location of the terminal and other information and send the relevant information of the second cell to the terminal to indicate that the terminal is close to the prohibited area and needs to perform a target action to solve the interference problem. Optionally, after the terminal receives the measurement request message sent by the access network device for measurement, it can also directly determine whether to perform the target action to solve the interference problem based on the measurement result. That is, after the terminal performs measurement based on the measurement request configured by the access network device, it can report the measurement result to the access network device and solve the interference problem through the instruction of the access network device. The terminal can also independently decide whether to perform the target action to solve the interference problem based on the measurement result, so that after the terminal obtains the measurement result according to the measurement request, it can flexibly solve the interference problem caused by the terminal approaching the prohibited area in a variety of ways.

[0233] Storing first information; the first information is used to indicate that the terminal does not respond to the paging message;

[0234] Do not respond to paging messages.

[0235] Specifically, when the terminal is stationed in the first cell and receives a paging message, that is, when the terminal is close to the prohibited area and receives the paging message, the terminal can select a non-protected frequency to send a service request message to avoid interference problems. The terminal can also send terminal information related to the second cell, MICO mode-related parameters and / or DRX parameters to the second device so that the network side communicates with the terminal at an appropriate time to solve the interference problem caused by the terminal responding to the paging message when close to the prohibited area, thereby reducing network interference. The terminal can also transmit data with the network only when it determines that the current altitude is greater than the protection altitude, that is, when it determines that the terminal will not interfere with the prohibited area, to avoid interference with the prohibited area. In addition, when the terminal is close to the prohibited area and receives the paging message, the terminal can also store the first information to indicate and record that the terminal did not respond to the paging message, and after the terminal moves out of the prohibited area, communicate between the networks based on the first information. The terminal may also not respond to the paging message, that is, the terminal does not take any action to respond to the paging message, thereby avoiding interference with the prohibited area. That is, in an embodiment of the present application, when the terminal is close to a prohibited area and receives a paging message, the terminal can flexibly solve and avoid interference problems caused by the terminal responding to the paging message in a variety of ways, effectively reducing network interference and improving network quality.

[0236] Optionally, the method further includes:

[0237] When it is determined that the user has moved out of the prohibited transmission area, a registration request message or a service request message is sent.

[0238] Specifically, when the terminal determines that it has moved out of the prohibited transmission area, that is, when the terminal is no longer close to the prohibited transmission area, the terminal can resend the registration request message or service request message to promptly restore normal communication with the network. Optionally, the terminal can determine whether it has moved out of the prohibited transmission area by measuring the strength of the second cell, measuring the distance to the second cell, etc., or by other means, and this is not limited in the embodiments of the present application.

Optionally, after the terminal receives the measurement request message sent by the access network device for measurement, it can also directly determine whether to perform the target action to solve the interference problem based on the measurement result. Therefore, after receiving the measurement request message sent by the first device, the terminal can effectively solve the interference problem caused when the terminal is close to the prohibited area.

[0270] Step 400: Send relevant information about a second cell adjacent to a first cell to a terminal; the relevant information about the second cell adjacent to the first cell includes at least one of the following:

[0280] In the method of the above embodiment, the second device sends relevant information of the second cell adjacent to the first cell to the terminal, so that the terminal can obtain relevant information of the second cell in a timely manner through the second device. After receiving the relevant information of the second cell, the terminal can determine that the terminal is close to the prohibited area based on the relevant information of the second cell and obtain specific information such as the protection height and protection frequency of the prohibited area overlapping with the coverage area of the second cell. Then, by selecting a non-protected frequency, stopping sending and / or receiving data, sending terminal information related to the second cell, MICO mode related parameters and / or DRX parameters to the first device and / or the second device, etc., it can effectively solve the interference problem caused by the terminal performing data transmission when it is close to the prohibited area, reduce network interference, and improve network quality.

[0281] Optionally, sending relevant information about a second cell adjacent to the first cell to the terminal includes:

[0282] A registration acceptance message is sent to the terminal; the registration acceptance message carries relevant information of a second cell adjacent to the first cell.

[0283] Specifically, in an embodiment of the present application, the second device can carry relevant information of the second cell adjacent to the first cell in the registration acceptance message sent to the terminal, thereby utilizing existing signaling to provide the terminal with relevant information of the second cell more quickly and conveniently, effectively improving the efficiency of the terminal in obtaining relevant information of the second cell.

[0285] Relevant information about a second cell adjacent to the first cell and sent by the first device is received.

[0286] Specifically, in an embodiment of the present application, after the second device obtains relevant information of a second cell adjacent to the first cell from the first device, it can send the relevant information of the second cell to the terminal, so that the terminal can effectively obtain relevant information of the second cell through multiple methods and channels, thereby improving the flexibility of the terminal in obtaining relevant information of the second cell.

[0287] Optionally, the method further includes:

[0288] Receive terminal information related to the second cell, MICO mode related parameters and / or DRX parameters from the terminal.

[0289] Specifically, when the terminal is close to the prohibited area, the terminal can send terminal information related to the second cell, MICO mode related parameters and / or DRX parameters to the second device; optionally, the terminal information related to the second cell includes at least one of the following: the time when the terminal enters the second cell, the time when the terminal moves out of the second cell, whether the terminal stops sending and / or receiving data in the second cell, the time period when the terminal sends and / or receives data, the time period when the terminal stops sending and / or receiving data, and whether the terminal is affected by the prohibited area; optionally, after receiving the above-mentioned terminal information related to the second cell, MICO mode related parameters and / or DRX parameters sent by the terminal, the second device can select a suitable time and a suitable method to communicate with the terminal according to the above information to solve the interference problem caused by the terminal when it is close to the prohibited area and reduce network interference.

[0294] Figure 5 One of the interactive flow diagrams of the communication method provided in the embodiment of the present application is as follows:

[0295] 0a. The first device RAN sends an NG establishment request to the second device AMF, where the message includes relevant information about the second cell adjacent to the first cell. That is, the first device sends relevant information about the second cell adjacent to the first cell to the second device.

[0296] 0b. AMF sends an NG establishment response to RAN.

[0297] Optionally, the network may send relevant information of a second cell adjacent to the first cell to the terminal in at least one of manner a, manner b, and manner c.

[0298] Among them, the method of method a is as follows:

[0299] 1. The terminal sends a registration request message to the second device AMF.

[0300] 2. The second device AMF sends a registration reply message to the terminal; wherein the registration reply message carries relevant information of the second cell adjacent to the first cell, so that the terminal can obtain relevant information of the second cell in a timely and effective manner through the second device.

[0301] That is, when the first device RAN establishes an NG interface with the AMF, the first device RAN node provides the cell information to the second device AMF. During the terminal registration process, the second device AMF allocates a registration area for the terminal. If the registration area includes a prohibited area, the second device AMF includes relevant information about the second cell in the registration acceptance message.

[0302] Method b is as follows:

[0303] 1. The terminal sends an RRC message to the first device RAN; wherein the RRC message is used for a registration request of the terminal, and the RRC message carries relevant information of a second cell adjacent to the first cell.

[0304] 2. The first device sends an N2 message to the second device AMF, where the message includes a registration request.

[0305] 3. The second device, the AMF, sends an N2 message to the first device, the RAN, which includes information such as registration acceptance, air terminal indication, and registration area. Based on the registration area and the information about the second cell adjacent to the first cell received from the third device, the OAM, the first device, the RAN, determines whether the registration area includes a second cell that overlaps with the prohibited area. If so, the first device, the RAN, sends information about the second cell adjacent to the first cell to the terminal.

[0306] 4. The first device RAN sends an RRC message to the terminal. The RRC message is used to indicate registration acceptance. The RRC message carries relevant information of a second cell adjacent to the first cell.

[0307] That is, the second device AMF sends the registration area and air terminal indication of the terminal to the first device RAN. If the registration area includes a prohibited area, the first RAN sends relevant information of the second cell to the terminal.

[0308] The method of method c is as follows:

[0309] 1. The first device RAN may broadcast the information or send information about a second cell adjacent to the first cell to the terminal through an RRC message. That is, when the first device RAN broadcasts the cell information, the broadcast message includes information such as the second cell identifier, a transmission prohibition indication, a protection frequency, and a protection altitude.

[0310] In an embodiment of the present application, the terminal can obtain relevant information of the second cell by receiving broadcast messages and / or signaling sent by the first device or the second device, thereby accurately and efficiently obtaining relevant information of the second cell in multiple ways, effectively improving the flexibility of the terminal in obtaining relevant information of the second cell.

[0311] Figure 6 The second interactive flow diagram of the communication method provided in the embodiment of the present application is as follows:

[0312] 1. The terminal monitors, based on cell broadcast information and / or locally stored information about a second cell adjacent to the first cell, that the second cell includes a cell covering the prohibited area, that is, the coverage area of the second cell overlaps with the prohibited area.

[0313] 2a. The terminal selects a non-protected frequency according to the frequency in the cell broadcast message, or executes step 2b-5.

[0314] 2b. If the terminal detects that the signal strength of the second cell covering the prohibited area reaches a threshold, or the distance to the second cell covering the prohibited area reaches a threshold, or the height of the terminal is x meters above the protection height, the terminal can perform a target action to resolve the interference problem during data transmission when the terminal is close to the prohibited area.

[0315] For example, when the terminal monitors that the signal strength of the second cell reaches a threshold value, or determines based on sensor information (such as speed, direction, and altitude) that it will enter an adjacent cell covering a prohibited area after a specific time period, or the distance between the terminal and the second cell reaches a threshold value, the terminal stops sending data, signaling, and wireless signals, turns off the radio frequency module, and does not respond to paging.

[0316] Prior to this, the terminal may send information related to the prohibited area of the terminal to the first device RAN or the second device AMF, such as entering the idle state / stopping data transmission after sending the information, the time when the terminal is expected to enter the second cell covering the prohibited area, etc. The terminal may also send information related to the prohibited area of the terminal to the drone air traffic management UTM / drone service provider USS. The UTM / USS may decide to modify the flight path / movement trajectory of the terminal based on the information provided by the terminal so that the terminal avoids the prohibited area. The UTM / USS provides the terminal with the updated flight path / movement trajectory.

[0317] When the terminal's altitude is above the "protection altitude + x meters," it sends data, signaling, and radio signals, and responds to paging. When the terminal's altitude is above the protection altitude but below the "protection altitude + x meters," it stops sending data, signaling, and radio signals, turns off the RF module, and does not respond to paging. This behavior also applies to terminals located in a secondary cell covering a prohibited area.

[0318] 3. The terminal determines terminal information related to the second cell, or determines a MICO or DRX parameter based on the terminal information related to the second cell. Optionally, the terminal information related to the second cell may include a time when the terminal enters a prohibited area / the second cell covering the prohibited area, a time when the terminal exits the prohibited area / the second cell covering the prohibited area, whether the second cell stops sending data / signaling / radio signals in the prohibited area / the second cell covering the prohibited area, a time period during which data / signaling / radio signals can be sent, a time period during which data / signaling / radio signals are stopped, whether the terminal is affected by the prohibited area, etc.

[0319] 4. The terminal sends an RRC message (terminal information related to the second cell / MICO parameters / DRX parameters) to the first device RAN, and the first device RAN sends an N2 message (terminal information related to the second cell / MICO parameters / DRX parameters) to the second device AMF. Alternatively, the terminal sends a non-access stratum NAS message (terminal information related to the second cell / MICO parameters / DRX parameters) to the second device AMF.

[0320] 5. The terminal stops sending signaling, data, wireless signals, and does not respond to paging.

[0321] In an embodiment of the present application, when the terminal is close to a prohibited area, it can select a non-protected frequency, stop sending and / or receiving data, send terminal information related to the second cell, MICO mode related parameters and / or DRX parameters to the first device and / or the second device, etc., thereby effectively solving the interference problem caused by the terminal performing data transmission when it is close to the prohibited area, reducing network interference and improving network quality.

[0322] Figure 7 The third interactive flow diagram of the communication method provided in the embodiment of the present application is as follows:

[0323] 1. For a connected terminal, the first device RAN finds that an adjacent cell of the cell where the terminal is currently staying overlaps with a prohibited area, or that the information of the adjacent cell of the staying cell includes information of the prohibited area, that is, the coverage area of the second cell overlaps with the prohibited area.

[0324] 2. If the cell supports non-protected frequencies, the first device RAN configures the frequency of the terminal as a non-protected frequency.

[0325] 3. The terminal uses non-protected frequencies.

[0326] 4. The first device RAN sends a measurement request to the terminal, where the message includes information such as the second cell identifier, the second cell center location, the distance threshold, the signal strength threshold, and the height threshold.

[0327] 5. The terminal sends a measurement report to the first device RAN, including information such as the second cell identifier, the distance between the terminal and the second cell, the signal strength of the second cell, the height of the terminal, distance threshold reached, signal strength threshold reached, and height threshold reached.

[0328] 6. The first RAN device sends an RRC message to the terminal, which carries relevant information about the second cell, such as prohibited area indication information, second cell identification information, protection frequency, protection altitude, stop sending, or first indication information; wherein the first indication information is used to instruct the terminal to stop sending data, signaling, or wireless signals.

[0329] 7. The terminal performs different operations based on the relevant information of the second cell. For example:

[0330] 1) The terminal stops sending data, signaling, and wireless signals according to the first instruction.

[0331] 2) The terminal selects a non-protection frequency based on the protection frequency.

[0332] 3) According to the protection height, when the terminal position is higher than the protection height or higher than the protection height + x meters, the terminal sends data, signaling, and wireless signals.

[0333] 4) The terminal determines the time when data can be sent, the active time, MICO parameters, and DRX parameters based on the restricted zone information and its own information (such as flight path, speed, altitude, direction, and sensor data), and sends the MICO parameters and DRX parameters to the second device (AMF). Optionally, the terminal determines altitude information based on information from a digital barometer, flight attitude based on information from an electronic gyroscope, speed based on information from an ultrasonic velocity meter, a pitot tube, or a micro-differential pressure wind speed sensor, and distance to the destination based on radar or satellite positioning.

[0334] 5) The terminal determines the terminal information related to the second cell and sends the information to the second device AMF. The second device AMF can determine the MICO parameters and DRX parameters based on the information and send the information to the SMF / PCF / NEF / NWDAF.

[0335] When the terminal's cell changes, if the UE believes it is still in the prohibited area, the terminal's behavior is the same as step 7. If the terminal moves out of the prohibited area, the first device RAN sends new configuration information and a measurement request to the terminal. The terminal will perform different operations based on the RAN's request.

[0336] In an embodiment of the present application, for a connected terminal, the first device RAN sends relevant information of the second cell to the terminal based on information such as the location reported by the terminal, so that the terminal can effectively solve the interference problem caused when the terminal approaches a prohibited area based on the relevant information of the second cell, thereby reducing network interference.

[0337] Figure 8 The fourth interactive flow diagram of the communication method provided in the embodiment of the present application is as follows:

[0338] 1a-1b, the second device AMF or the first device RAN sends relevant information of the second cell adjacent to the first cell to the terminal, including the second cell list, protection frequency, protection height, protection geographical area and other information.

[0339] 2. The terminal stores the information received in step 1.

[0340] 3. The terminal enters the idle state or RRC inactive state.

[0341] 4. The terminal monitors the cells stored in the list.

[0342] 5. The terminal does not send data / signaling / wireless signals.

[0343] 6. Network paging terminal.

[0344] 7a-8a. The terminal selects a non-protected frequency or the UE detects that the current altitude is above the protected altitude or the protected altitude + x meters. The terminal sends a service request. The terminal may carry MICO parameters, DRX parameters, or terminal information related to the second cell in the service request.

[0345] 7b. Optionally, the terminal may locally store first indication information, which is used to indicate that the terminal has not responded to the paging indication.

[0346] 8b. The terminal detects that the vehicle has been moved out of the prohibited area.

[0347] 9. The terminal resumes sending registration requests and service requests to the second device AMF.

[0348] In an embodiment of the present application, when the terminal enters the idle state, the first device RAN cannot obtain the cell where the terminal resides, and therefore cannot control the terminal to perform measurements. Therefore, the terminal can autonomously decide to perform the target action based on the relevant information of the second cell to solve the interference problem when the terminal is close to the prohibited area and improve the network quality.
