Please refer to Figure 2. Figure 2 is a flow chart of a neighbor cell measurement method provided by an embodiment of the present application. The neighbor cell measurement method includes step 201. The method execution subject shown in Figure 2 may be a terminal device, or the subject may be a chip in the terminal device. The method execution subject shown in Figure 2 takes the terminal device as an example. in:

201. If the time interval between the time when the satellite leaves the serving cell is less than or equal to the first threshold value or the timer for neighbor cell measurement times out, the terminal device measures the neighbor cell.

In the embodiment of this application, the serving cell refers to the cell that serves the terminal equipment. If a cell is within the coverage of a satellite, the satellite can provide services to the cell.

In the embodiment of this application, the terminal device can be triggered to measure the neighboring cell through the following condition 1 or condition 2.

Condition 1: If the time interval from the time when the satellite leaves the serving cell is less than or equal to the first threshold, the terminal device measures the neighboring cell.

For example, assuming that the first threshold is 10 minutes, it is assumed that the satellite above the serving cell will leave the serving cell at 8 am. Then the terminal equipment can start measuring the neighboring area from 7:50 am.

In a possible implementation, the network device may also send first indication information to the terminal device, where the first indication information indicates the first threshold value. Correspondingly, the terminal device may receive the first indication information sent by the network device. Based on this possible implementation, the first threshold value can be made more flexible.

Optionally, the first indication information may be carried in a broadcast message or dedicated signaling. Optionally, the broadcast message may be a system message, such as a SIB message. Optionally, the dedicated signaling may be RRC signaling. Optionally, if the first indication information is carried in a broadcast message, the terminal device may receive the first indication information in the idle state. Optionally, if the first indication information is carried in dedicated signaling, the terminal device may receive the first indication information in the connected state.

In another possible implementation, the first threshold value may also be pre-specified by the protocol. Based on this possible implementation, transmission resources can be saved.

In a possible implementation, the terminal device may determine whether the time interval from the time when the satellite leaves the serving cell is less than or equal to the first threshold value when in the connected state.

Condition 2: If the timer used for neighbor cell measurement times out, measure the neighbor cell.

In a possible implementation, the terminal device can start the timer when in the connected state, and then determine whether the timer times out.

In a possible implementation, the network device may send second indication information to the terminal device, where the second indication information indicates the timer. Correspondingly, the terminal device may receive the second indication information sent by the network device. The terminal device may start the timer when receiving the second indication information. Based on this possible implementation, the timer can be made more flexible.

Optionally, the second indication information may be carried in dedicated signaling. Optionally, the dedicated signaling may be RRC signaling. The optional terminal device may receive the second indication information in the connected state.

It can be seen that through the method described in Figure 2, in the NTN scenario, the terminal device can trigger the terminal device to measure the neighboring cell in a timely manner.

Please refer to Figure 3. Figure 3 is a flow chart of a neighbor cell measurement method provided by an embodiment of the present application. The neighbor cell measurement method includes steps 301 to 302. The method execution subject shown in Figure 3 may be a terminal device, or the subject may be a chip in the terminal device. The method execution subject shown in Figure 3 takes the terminal device as an example. in:

301. The terminal equipment determines that neighbor cell measurement is enabled or the terminal equipment is in continuous coverage.

In the embodiment of the present application, enabling neighbor cell measurement indicates that the terminal device can perform neighbor cell measurement. Correspondingly, disabling neighbor cell measurement indicates that the terminal device does not need to perform neighbor cell measurement.

The continuous coverage of the terminal equipment means that the serving cell and neighboring cells of the terminal equipment are both within the coverage area of the satellite. The fact that the terminal equipment is in discontinuous coverage means that the adjacent area of the terminal equipment is not within the coverage range of the satellite. Satellites can provide services to cells within their coverage. Therefore, in the embodiment of this application, the terminal device only needs to perform neighbor cell measurement if the terminal device is in continuous coverage. If the terminal device is in discontinuous coverage, the terminal device does not need to perform neighbor cell measurements, because the satellite does not provide services to the neighbor cell, and even if the terminal device accesses the neighbor cell, normal communication cannot be performed.

In this embodiment of the present application, the terminal device may determine whether neighbor cell measurement is enabled or the terminal device is in continuous coverage in the following two ways.

Method 1: The terminal device can determine by itself whether neighbor cell measurement is enabled or the terminal device is in continuous coverage.

For example, the terminal device can determine by itself that it is in continuous coverage. If the terminal device determines that it is in continuous coverage, the terminal device determines to enable neighbor cell measurement. Based on the first method, the signaling interaction between the terminal and the network device can be reduced.

Method 2: The network device instructs the terminal device to enable neighbor cell measurement or instructs the terminal device to provide continuous coverage. For example, the network device sends third indication information to the terminal device, and the third indication information indicates that neighbor cell measurement is enabled or indicates that the terminal device is in continuous coverage. After receiving the third indication information, the terminal equipment determines to enable neighbor cell measurement or the terminal equipment is in continuous coverage based on the third indication information. For example, as shown in Figure 4, Figure 4 includes steps 401 to 403.

Based on the second method, the complexity of the terminal device can be reduced.

In a possible implementation, the third indication information may be carried in a broadcast message or dedicated signaling. Optionally, the broadcast message may be a system message, such as a SIB message. Optionally, the dedicated signaling may be RRC signaling. Optionally, if the third indication information is carried in the broadcast message, the terminal device may receive the third indication information in the idle state. Optionally, if the third indication information is carried in dedicated signaling, the terminal device may receive the third indication information in the connected state.

302. If the time interval from the time when the satellite leaves the serving cell is less than or equal to the first threshold value or the timer for neighbor cell measurement times out, the terminal device measures the neighbor cell.

In the implementation of this application, after the terminal equipment determines that neighbor cell measurement is enabled or the terminal equipment is in continuous coverage, it determines whether the time interval from the moment when the satellite leaves the serving cell is less than or equal to the first threshold value, or determines whether the time interval for neighbor cell measurement is enabled. Whether the zone measurement timer has expired. For the specific implementation of step 302, please refer to the description under step 201, which will not be described again here.

In the method described in Figure 3, after the terminal device determines that neighbor cell measurement is enabled or the terminal device is in continuous coverage, it then determines whether the time interval from the moment when the satellite leaves the serving cell is less than or equal to the first threshold value or Determine whether the timer used for neighbor cell measurement has timed out, which will help prevent the terminal equipment from doing useless work and avoid waste of power consumption of the terminal equipment.

Please refer to Figure 5. Figure 5 is a flow chart of a neighbor cell measurement method provided by an embodiment of the present application. The neighbor cell measurement method includes steps 501 to 503. The method execution subject shown in Figure 5 can be a terminal device, or the subject can be a terminal. The chip in the device. The method execution subject shown in Figure 5 takes the terminal device as an example. in:

501. The terminal equipment determines that neighbor cell measurement is enabled or the terminal equipment is in continuous coverage.

502. If the time interval between the time when the satellite leaves the serving cell is less than or equal to the first threshold value or the timer for neighbor cell measurement times out, the terminal device measures the neighbor cell.

For the specific implementation of steps 501 to 502, please refer to the corresponding descriptions above and will not be described again here.

503. The terminal device sends fourth instruction information to the network device. The fourth instruction information instructs the terminal device to start neighbor cell measurement. Correspondingly, the network device may receive the fourth indication information.

In this embodiment of the present application, the terminal device may send fourth indication information to the network device when starting neighbor cell measurement. Optionally, after receiving the fourth indication information, the network device may stop scheduling the terminal device. Based on the method described in Figure 3, the network device can be notified in time that the terminal device starts performing neighbor cell measurements, so that the network device can stop scheduling the terminal device in time to avoid transmission failure.

Optionally, if the terminal device determines by itself that neighbor cell measurement is enabled or that the terminal device is in continuous coverage, instead of determining that neighbor cell measurement is enabled or that the terminal device is in continuous coverage through the above third indication information, the terminal device starts neighbor cell measurement. Send fourth indication information to the network device during zone measurement. Because the terminal device determines by itself to enable neighbor cell measurement or when the terminal device is in continuous coverage, the network device cannot determine when the terminal device starts performing neighbor cell measurement.

Optionally, if the network device indicates through the third indication information to enable neighbor cell measurement or the terminal device is in continuous coverage, the network device itself can determine when the terminal device starts to perform neighbor cell measurement. In this case, the terminal device can The fourth instruction information is not sent to the network device, which is beneficial to saving transmission resources.

Optionally, if the network device indicates to enable neighbor cell measurement through the third indication information or the terminal device is in continuous coverage, the terminal device may also send the fourth indication information to the network device, which is beneficial to saving computing resources of the network device.
