[0071] In a satellite communication system of a transparent architecture or a regenerative architecture, a base station broadcasts time information of a serving cell satellite stopping serving a current serving cell and time information of a neighboring cell satellite starting to cover the current cell in system information. Based on the system information, a terminal device in the cell can determine a time for performing cell measurement.

[0170] It can be understood that, since the base station is generally moving relative to the ground, the serving base station can only provide service for the cell in a certain time period, and therefore, in the store-and-forward mode, the service link between the serving base station and the terminal device in the cell can be maintained for a certain time period; similarly, the feeder link between the serving base station and the ground device in the cell can also be maintained for a certain time period, and therefore, the serving base station can provide store-and-forward service for the cell, and can also be maintained for a certain time period, and information related to these times is the store-and-forward mode service time information in the embodiments of the present application.

[0171] In the embodiments of the present application, the service cell satellite store-and-forward mode service time information can comprise at least one of a service link start service time, a service link stop service time, a feeder link start service time, a feeder link stop service time, a store-and-forward mode duration, a store-and-forward mode start working time, and a store-and-forward mode stop working time, and can also comprise other time information during which the serving satellite can provide service for the cell, and the specific embodiments are not limited herein.

[0172] In the embodiments of the present application, the service link start service time, the service link stop service time, the feeder link start service time, and the feeder link stop service time can be a specific time, for example, a coordinated universal time (UTC) time; or can be an offset, for example, an offset relative to the system time UTC, which is not limited here.

[0173] In a possible implementation, the satellite service message further includes service mode information and satellite architecture type information, the service mode information indicating whether the working mode of the serving base station is a store-and-forward mode.

[0174] In the embodiments of the present application, the satellite architecture type information can describe the satellite architecture type corresponding to the base station, for example, an NTN architecture, the communication between the terminal and the base station being implemented through the forwarding of the satellite, the terminal device, the base station, and the core network device all being on the ground; or a regenerated NTN architecture, the communication between the terminal device and the core network being implemented through the forwarding of the base station, the base station being located on the satellite, and the terminal device and the core network device being located on the ground. Or another regenerated NTN architecture, the base station and part of the core network device being on the satellite, for example, a first architecture type, in which the base station and a separated mobile management entity (MME) are on the satellite. In addition, it can also be other satellite architecture types, for example, a second architecture type, in which the base station and a complete core network element are on the satellite, the complete core network element including the mobile management entity (MME), which is not limited here.

[0175] In a possible implementation, the satellite service message includes store-and-forward mode service time information of a serving cell satellite and store-and-forward mode service time information of at least one neighbor satellite.

[0176] In the embodiments of the present application, the store-and-forward mode service time information of any one of the at least one neighbor satellite can include at least one of the service link start service time, the service link stop service time, the feeder link start service time, the feeder link stop service time, the store-and-forward mode duration, the store-and-forward mode start working time, and the store-and-forward mode stop working time, and can further include other time information that the neighbor satellite can provide service for the cell, which is not limited here.

[0177] In the embodiments of the present application, the service link start service time, the service link stop service time, the feeder link start service time, and the feeder link stop service time can be a specific time, for example, a coordinated universal time (UTC) time; or can be an offset, for example, an offset relative to the system time UTC, which is not limited here.

[0178] In the embodiments of the present application, the storage and forwarding mode service time information of the neighboring satellite is similar to the storage and forwarding mode service time information of the serving satellite. The neighboring satellite service message can also include the storage and forwarding mode service time information corresponding to the neighboring satellite, which describes the time information during which the neighboring base station can provide storage and forwarding service for the terminal device in the corresponding cell. Therefore, the content is similar to the description of the storage and forwarding mode service time information of the serving satellite broadcast by the serving base station, and will not be limited here.

[0179] In a possible implementation, in the case where the satellite service message includes the storage and forwarding mode service time information of the serving cell satellite and the storage and forwarding mode service time information of at least one neighboring satellite, the satellite service message further includes satellite architecture type information, which is the satellite architecture type of the neighboring satellite. The satellite architecture type information is similar to the satellite architecture type information of the serving satellite, and will not be repeated here.

[0180] In the embodiments of the present application, the satellite service message of the serving cell satellite can be carried by a system message, for example, the satellite service message can be carried by a system information block type 3 (SIB3) message, a (system information block type 3 for narrowband IoT, SIB3-NB) message, a system information block type 31 (SIB31) message, a (system information block type 31 for narrowband IoT, SIB31-NB) message, or other system messages. The specific system message will not be limited here.

[0181] For example, the storage and forwarding mode service time information is carried in the SIB3 message:

[0182] t-Service-r17: Time information on when an NTN cell is going to stop serving the area it is currently covering, as specified in TS 36.304 [4]. This field applies for service link switches in NTN quasi-Earth fixed cells and feeder link switches for both NTN quasi-Earth fixed and earth-moving cells.

[0183] The storage and forwarding mode service time information of the neighbor satellite can be carried in a system message, such as a system information block type 33 (SIB33) message, a system information block type 33 for narrowband IoT (SIB33-NB) message, and the like. The satellite service message does not limit the system information block type 33:

[0184] In a possible implementation manner, the satellite service message can also be carried by other messages. For example, in a case where the terminal device establishes a communication connection with the base station, the base station can directly send the satellite service message to the terminal device, or can carry the satellite service message by using other messages such as dedicated signaling. The specific implementation is not limited here.

[0185] 402. The terminal device determines a time for performing a measurement task according to the satellite service message.

[0186] After receiving the satellite service message broadcast by the serving base station, the terminal device can determine a time for performing a measurement task according to the satellite service message. The satellite service message includes storage and forwarding mode service time information of a serving cell satellite and storage and forwarding mode service time information of at least one neighbor satellite.

[0187] In the embodiments of the present application, the measurement task can be an intra-frequency measurement or an inter-frequency measurement. For example, the measurement task can be an intra-frequency cell measurement or an inter-frequency cell measurement. The specific implementation is not limited here.

[0188] In a possible implementation, the terminal device can determine the time for performing the measurement task according to the store-and-forward mode service time information of the serving cell satellite in the satellite service message.

[0189] Specifically, when the measurement task is cell measurement, the terminal device can determine the cell measurement time according to the store-and-forward mode service time information of the serving cell satellite in the satellite service message, and there can be multiple determination manners, for example:

[0190] In a possible implementation, the terminal device determines the time for performing the cell measurement according to the store-and-forward mode service time information of the serving cell satellite, and the time for performing the cell measurement is before the service link stop service time.

[0191] In this possible implementation, for the terminal device that establishes communication with the base station, the cell measurement task is performed before the service link stop service time, and the cell that can be re-camped or re-accessed can be determined before the service link stop service time, so as to avoid communication interruption of the terminal device.

[0192] In a possible implementation, the terminal device determines the time for performing the cell measurement according to the store-and-forward mode service time information of the serving cell satellite, and the time for performing the cell measurement is before the feeder link stop service time.

[0193] In this possible implementation, for the terminal device that establishes communication with the base station, the cell measurement task is performed before the feeder link stop service time, and the cell that can be re-camped or re-accessed can be determined before the feeder link stop service time, so as to avoid communication interruption of the terminal device.

[0194] In another possible implementation, the terminal device determines the time for performing the cell measurement according to the store-and-forward mode service time information of the serving cell satellite, and the time for performing the cell measurement is before the store-and-forward mode stop working time.

[0195] In this possible implementation, for the terminal device that establishes store-and-forward mode communication with the base station, the cell measurement is performed before the store-and-forward mode stop working time, and the terminal device can obtain the measurement result before the store-and-forward mode stop working time, so as to determine the cell that can be re-camped or re-accessed, and avoid communication interruption of the terminal device.

[0196] In another possible implementation, the terminal device determines the time for performing the cell measurement according to the store-and-forward mode service time information of the serving cell satellite, and the time for performing the cell measurement is within the store-and-forward mode duration.

[0197] In the possible implementation, for the terminal device that establishes the store-and-forward mode communication with the base station, the cell measurement is performed during the store-and-forward mode duration, and the terminal device can obtain the measurement result before the store-and-forward mode stop working time, and determine the cell that can be re-camped or the cell that can be re-accessed, thereby avoiding the communication interruption of the terminal device.

[0198] It can be understood that after receiving the satellite service message broadcast by the base station, the terminal device can perform the cell measurement in order to guarantee the communication of the terminal device, regardless of whether the terminal device establishes the connection with the base station. In the embodiment of the application, the terminal device performs the cell measurement. Specifically, the terminal device can obtain the signals of multiple cells, and the terminal device performs the measurement on the obtained cell signals in terms of the signal quality and the signal strength, so as to determine the service quality that can be provided by each cell. The terminal device can perform the corresponding processing according to the measurement result, for example, determine the appropriate cell access, and the like.

[0199] In a possible implementation, the terminal device can further determine the time for starting to perform the measurement task according to the store-and-forward mode service time information of the at least one neighbor satellite. It can be understood that the terminal device can determine the specific time for starting to perform the measurement task according to the store-and-forward mode service time information of the at least one neighbor satellite.

[0200] In the embodiment of the application, the store-and-forward mode service time information of any one of the at least one neighbor satellite can include at least one of the service link start service time, the service link stop service time, the feeder link start service time, the feeder link stop service time, the store-and-forward mode duration, the store-and-forward mode start working time and the store-and-forward mode stop working time, and can further include other time information that the neighbor satellite can provide the service for the cell, which is not limited here.

[0201] In the embodiment of the application, the service link start service time, the service link stop service time, the feeder link start service time and the feeder link stop service time can be a specific time, for example, the coordinated universal time (UTC) time, or can be an offset, for example, the offset relative to the system time UTC, which is not limited here.

[0202] In the embodiments of the present application, the storage and forwarding mode service time information of the neighboring satellite is similar to the storage and forwarding mode service time information of the serving satellite, and the storage and forwarding mode service time information of the neighboring satellite can also be included in the neighboring satellite service message. The storage and forwarding mode service time information describes time information in which the neighboring base station can provide storage and forwarding services for the terminal device in the corresponding cell. Therefore, the content is similar to the description of the storage and forwarding mode service time information of the serving satellite broadcast by the serving base station, and will not be limited here.

[0203] In a possible implementation manner, in the case where the satellite service message includes the storage and forwarding mode service time information of the serving cell satellite and the storage and forwarding mode service time information of at least one neighboring satellite, the satellite service message further includes satellite architecture type information, which is the satellite architecture type of the neighboring satellite. The satellite architecture type information is similar to the satellite architecture type information of the serving satellite, and will not be repeated here.

[0204] In the embodiments of the present application, the terminal device determines the time of cell measurement according to the satellite service message including the storage and forwarding mode service time information. Compared with the existing cell stop service time, the storage and forwarding mode service time information includes more available information, and the terminal device can determine a more accurate time suitable for performing the measurement task.

[0205] For example, the storage and forwarding mode service time information includes the feeder link stop service time t1 and the service link stop service time t2, and the base station stops the feeder link service of the cell at t1, stops the service link service of the cell at t2, and finally completely stops the service of the cell at t3. In this scenario, after receiving the satellite service message including the feeder link stop service time t1, the terminal device can determine the time of performing the measurement task, which is before t1. If the satellite service message does not include the storage and forwarding mode service time information, the terminal device can only obtain the stop service time t3, and the determined time of performing the measurement task is before t3. Therefore, the terminal device may still not perform the cell measurement in the storage and forwarding mode, and no cell can be accessed, so that the communication of the terminal device is interrupted.

[0206] In summary, in the embodiments of the present application, the storage and forwarding mode service time information is included in the satellite service message. Compared with the cell stop service time, the storage and forwarding mode service time information has more available information, and the terminal device can determine a more accurate time suitable for performing the measurement task, thereby improving the measurement effect of the terminal device.

[0207] For example, FIG. 5 is a flowchart of another measurement method provided by the embodiments of the present application. Referring to FIG. 5, the measurement method can include the following steps:

[0208] 501. The terminal device receives satellite coverage prediction information broadcast by a base station.

[0209] The base station broadcasts satellite coverage prediction information for each cell. Correspondingly, the terminal device receives the satellite coverage prediction information broadcast by the base station, and the satellite coverage prediction information includes predicted storage and forwarding mode service time information of at least one satellite entering a current serving cell area in a subsequent period of time. The serving cell is a cell that provides communication services for the terminal device.

[0210] In the embodiments of the present application, the terminal device can be an idle state terminal that has not established a communication connection with any base station, a connected state terminal that has established a connection with a certain base station, or a non-active state terminal. The specific embodiments are not limited here.

[0211] In a possible implementation, the satellite coverage prediction information can include service time information of at least one satellite for the cell. The service time information can include at least one of a service link start service time, a service link stop service time, a feeder link start service time, a feeder link stop service time, a storage and forwarding mode duration, a storage and forwarding mode start working time, and a storage and forwarding mode stop working time.

[0212] In a possible implementation, the satellite coverage prediction information can include satellite architecture type information. The satellite architecture type information can describe a satellite architecture type corresponding to the base station, such as an NTN architecture. The communication between the terminal and the base station is implemented through the forwarding of the satellite, and the terminal device, the base station, and the core network device are all on the ground. The satellite architecture type information can also be a regenerated NTN architecture. The communication between the terminal device and the core network is implemented through the forwarding of the base station, and the base station is located on the satellite, and the terminal device and the core network device are located on the ground. The satellite architecture type information can also be another regenerated NTN architecture. The base station and part of the core network device are on the satellite, such as a first architecture type. In the first architecture type, the base station and a separated mobile management entity (MME) are on the satellite. In addition, the satellite architecture type information can also be other satellite architecture types, such as a second architecture type. In the second architecture type, the base station and a complete core network element are on the satellite, and the complete core network element includes a mobile management entity (MME). The specific embodiments are not limited here.

[0213] In the embodiments of the present application, the satellite coverage prediction information can be carried by a system message, such as an SIB32 message, an SIB32-NB message, or other messages. The specific embodiments are not limited here.

[0214] For example, the satellite coverage prediction information is included in the SIB32-NB message:

[0215] 502、The terminal device determines the out-of-coverage time period.

[0216] After receiving the satellite coverage prediction information, the terminal device can determine the out-of-coverage time period according to the satellite coverage prediction information, the out-of-coverage time period being a time period in which the terminal device has no satellite coverage.

[0217] Specifically, for example, the terminal device can determine, according to the satellite coverage prediction information, service time information of at least one satellite entering the current serving cell area in a subsequent time period, so as to determine a time at which each of the at least one satellite can cover a cell corresponding to the terminal device, and if there is no satellite covering the terminal device in a certain time period, determine the time period as an out-of-coverage time period of the cell, i.e., an out-of-coverage time period of the terminal device. For example, the terminal device determines, according to the satellite coverage prediction information, that base stations corresponding to satellites entering the current serving cell area in a subsequent time period include base station 1 and base station 2, the satellite base station 1 starts to cover the cell at t1, the base station 2 starts to cover the cell at t2, and the serving base station has stopped serving the cell at t3, which are arranged in time sequence as t3, t1, t2, and thus the terminal device can determine that the out-of-coverage time period is from t3 to t1 (t3, t1).

[0218] For example, FIG. 6 is a flowchart of another measurement method provided by an embodiment of the present application. Referring to FIG. 6, the measurement method can specifically include the following steps:

[0219] 601、The serving base station sends a satellite service message to the terminal device.

[0220] In a case where the terminal device is in a connected state and a communication connection is established with the serving base station, the serving base station can send a satellite service message to the terminal device, the satellite service message including storage and forwarding mode service time information of a serving cell satellite, the storage and forwarding mode service time information of the serving cell satellite indicating time information in which the serving satellite can provide storage and forwarding service for a cell corresponding to the terminal device in a storage and forwarding mode.

[0221] In this embodiment, the satellite service message sent by the serving base station to the terminal device is the same as the satellite service message in step 401, which is not described herein again.

[0222] In a possible implementation, the satellite service message further includes the satellite service message in step 501, which is not described herein again.
