In some embodiments, the first time information is used to indicate a first time, where the first time is a plurality of time slots, and the first time may be used to indicate a duration of the first measurement, for example, the first time is an L-th time slot and an M-th time slot, where the L-th time slot and the M-th time slot are respectively used to indicate a start time slot of the first measurement and an end time slot of the first measurement, and the ue 102 may determine, according to the first time information sent by the ue 101, that the L-th time slot to the M-th time slot are required for the first measurement.

In some embodiments, the first time information is used to indicate a first time window, e.g., the first time window is used to indicate a time required for the first measurement, e.g., the first time window represents an L-th time slot to an M-th time slot, the L-th time slot to the M-th time slot are used to indicate a time required for the first measurement, and the network device 102 receives the first time information sent by the user device 101 and determines the L-th time slot to the M-th time slot as a time required for the first measurement.

In some embodiments, the first time information is used to indicate a first time window, for example, the first time window is less than a time required for the first measurement, the first time window is a part of the time required for the first measurement, other parameters are indicated by another part of the time required for the first measurement, for example, the first time window is an L-th time slot to an M-th time slot, the L-th time slot to the M-th time slot are indicated by a part of the time required for the first measurement, other parameters are indicated by another part of the time required for the first measurement from the M-th time slot to the N-th time slot, the network device 102 receives the first time information sent by the user device 101, the network device 102 is preconfigured with other parameters, or obtains other parameters from the core network device, etc., the network device 102 may determine the time required for the first measurement according to the first time and other parameters.

Further, in some embodiments, after the network device 102 determines the time required for the first measurement, the time or time window for the first measurement may be configured for the user device 101 based on the time required for the first measurement, and the user device 101 performs the first measurement based on the configuration of the network device 102.

In some embodiments, the first measurement is used to acquire a GNSS position and/or the first measurement is a GNSS measurement.

In some embodiments, the time required for the first measurement may be referred to as GNSS position fix time duration, or the time required for the first measurement may comprise GNSS position fix time duration; alternatively, the time required for the first measurement may include a portion of GNSS position fix time duration. For example, the first duration is five time slots, i.e., GNSS position fix time duration is five time slots; for example, the first duration is five time slots, i.e., GNSS position fix time duration is less than five time slots, further, the first duration indicates GNSS position fix time duration and the time length of other processes, if the time length of other processes is X time slots, the UE may determine GNSS position fix time duration that the time length is 5-X; for example, the first duration is five time slots, i.e. GNSS position fix time duration is greater than five time slots, further, the first duration indicates GNSS position fix time duration a part of the time length, the other parameters indicate GNSS position fix time duration another part of the time length, and if the time length indicated by the other parameters is X time slots, the UE may determine GNSS position fix time duration to be 5+X.

In some embodiments, the first time information is carried by first signaling, which is a connection re-establishment completion message or a connection reconfiguration completion message, or other uplink message.

In some embodiments, the connection reestablishment completion message may be a feedback message that the user equipment 101 completes connection reestablishment of the user equipment 101 reported by the user equipment 101 to the network device 102, where the user equipment 101 completes transmission of the feedback message that connection reestablishment of the user equipment 101 is completed.

In some embodiments, the connection reestablishment complete message includes a radio resource control (Radio Resource Control, RRC) connection reestablishment complete message, that is, an rrcconnectionreestiblefound complete message, and the UE feeds back the rrcconnectionreestiblefound complete message to the network side during the RRC connection reestablishment procedure, and the RCC connection reestablishment is completed.

In some embodiments, the connection reestablishment complete message includes an RRC connection reestablishment complete message of the NB IoT device, i.e., an rrcconnectionreestiblesetcomplete-NB message, which the NB IoT UE feeds back to the network side during RRC connection reestablishment, RRC connection reestablishment complete.

In some embodiments, the connection reconfiguration complete message may be a user equipment 101 connection reconfiguration complete message reported by the user equipment 101 to the network device 102, where the user equipment 101 completes sending the user equipment 101 connection reconfiguration complete message, indicating that the user equipment 101 connection reconfiguration is complete.

In some embodiments, the connection reconfiguration complete message includes an RRC connection reconfiguration complete message (also referred to as a handover complete message) in the UE handover scenario, that is RRCConnectionReconfigurationComplete for HO case, without distinguishing the UE type, the UE performs RRC connection reconfiguration during cell handover, the UE feeds RRCConnectionReconfigurationComplete for HO case a message back to the network side, and RRC connection reconfiguration is completed.

In some embodiments, the first cell is a cell of the user equipment 101 that is connected before being reestablished, the second cell is a cell of the user equipment 101 that is connected after being reestablished, the coverage area of the user equipment 101 includes the second cell, or the coverage area of the user equipment 101 includes the first cell and the second cell, and the user equipment 101 may specifically be a base station or a core network to which the user equipment 101 is connected.

In some embodiments, the preset conditions are: the connection reestablishment of the ue 101 further includes that the ue 101 initiates a connection reestablishment procedure, or the connection state of the ue 101 meets a preset condition, or the network state of the ue 101 meets a preset condition, or the connection reconfiguration of the ue 101 fails, or the like.

In some embodiments, the connection state of the ue 101 conforms to a preset situation, such as the ue 101 changes from a CONNECTED state (CONNECTED state) to an IDLE state (IDLE state) or an INACTIVE state (INACTIVE state), and then changes from the IDLE state (IDLE state) or the INACTIVE state (INACTIVE state) to the CONNECTED state (CONNECTED state).

In some embodiments, the network status of the user equipment 101 corresponds to a preset situation, such as detecting a radio link failure of the connected cell, etc.

In some embodiments, the preset conditions are: the user equipment 101 performs connection reestablishment, the user equipment 101 is connected with a first cell before reestablishment, the user equipment 101 is connected with a second cell after reestablishment, the first cell and the second cell are non-terrestrial network (NTN) cells, wherein first time information is carried by a first signaling, and the first signaling is a connection reestablishment completion message.

In other words, in the case where the ue 101 performs connection reestablishment, and the ue 101 is connected to one NTN cell before reestablishment, and the ue 101 is connected to one NTN cell after reestablishment, the ue 101 may report the first time or the first time window in a connection reestablishment completion message.

In some embodiments, the user equipment 101 completes connection reestablishment, and the user equipment 101 feeds back a connection reestablishment completion message to the cell connected after reestablishment, i.e. the user equipment 101 reports the first time or the first time window to the cell connected after reestablishment by default.

For example, when the UE performs RRC connection reestablishment and the UE is connected to one NTN cell before reestablishing and the UE reestablishes to one NTN cell, the UE reports a first time or a first time window through an RRC reestablishment completion message.

In some embodiments, the preset conditions are: the user equipment 101 is subjected to connection reestablishment, the user equipment 101 is connected with a first cell before reestablishment, the user equipment 101 is connected with a second cell after reestablishment, the first cell is a ground network TN cell, the second cell is a non-ground network NTN cell, wherein first time information is carried by a first signaling, and the first signaling is a connection reestablishment completion message.

In other words, in case the user equipment 101 performs the reestablishment, and the user equipment 101 is connected to one NTN cell before the reestablishment, and the user equipment 101 reestablishes to one NTN cell, the user equipment 101 may report the first time or the first time window to the network equipment 102 in a connection reestablishment complete message.

For example, when the UE performs connection reestablishment, the UE is connected to a TN cell before reestablishing, and the UE reestablishes to an NTN cell, the UE reports a first time or a first time window through an RRC reestablishment completion message. In some embodiments, the first cell is a source cell where the ue 101 is handed over, the second cell is a target cell where the ue 101 is handed over, and the coverage area of the ue 101 includes the second cell, or the coverage area of the ue 101 includes the first cell and the second cell, where the ue 101 may specifically be a base station or a core network to which the ue 101 is connected.

In some embodiments, the preset conditions are: the handover of the ue 101, further, the situation meeting the preset condition includes that the serving cell of the ue 101 changes, for example, the serving cell of the ue 101 changes from the first cell to the second cell; the user equipment 101 receives the handover command, initiates a handover procedure, etc.

In some embodiments, the preset conditions are: the user equipment 101 is switched, the user equipment 101 is connected with a first cell before switching, the user equipment 101 is connected with a second cell after switching, the first cell and the second cell are non-ground network NTN cells, wherein first time information is carried by a first signaling, and the first signaling is a connection reconfiguration completion message or a switching completion message.

In other words, when the ue 101 performs handover, and the source cell of the handover is an NTN cell, and the target cell of the handover is an NTN cell, the ue 101 reports the first time or the first time window in the connection reconfiguration complete message.

In some embodiments, the user equipment 101 connection reconfiguration comprises RRC connection reconfiguration when the user equipment 101 switches.

For example, the UE performs handover, and the source cell of the handover is an NTN cell, and the target cell of the handover is an NTN cell. The UE reports the first time or the first time window through the RRC reconfiguration complete message.

In some embodiments, the preset conditions are: the user equipment 101 is switched, the user equipment 101 is connected with a first cell before being switched, the user equipment 101 is connected with a second cell after being switched, the first cell is a terrestrial network TN cell, the second cell is a non-terrestrial network NTN cell, wherein first time information is carried by a first signaling, and the first signaling is a connection reconfiguration completion message or a switching completion message.

In other words, when the ue 101 performs handover, and the source cell of the handover is an NTN cell, and the target cell of the handover is a TN cell, the ue 101 reports the first time or the first time window in the connection reconfiguration complete message.

For example, the UE switches, and the source cell of the switch is a TN cell, and the target cell of the switch is a NTN cell. The UE reports the first time or the first time window through an RRC reconfiguration complete message (i.e., a handover complete message).

In the time information determining method according to the embodiments of the present disclosure, steps 2102 to 2105 are optional embodiments, and are optionally performed before step 2101, and may be used to determine whether the first cell and/or the second cell support reporting the first time information.

In some embodiments, the first cell and/or the second cell supporting reporting the first time information refers to the first cell and/or the second cell supporting receiving the first time information reported by the user equipment 101, or the first cell and/or the second cell supporting configuring a time or a time window for the first measurement for the user equipment 101 based on receiving the first time information reported by the user equipment 101.

Step 2102, the network device 102 does not send first information to the user device 101, where the first information is used to configure the user device 101 to report first time information to the first cell.

In some embodiments, the first information is carried by at least one of a broadcast message, a system message, or a radio resource control, RRC, message.

In some embodiments, "not transmitting" may mean not expecting to not transmit, not expecting to transmit, and reserving transmission (withhold transmitting), which may be interpreted as transmitting but not expecting the recipient to respond to the transmitted content. The network device 102 does not send the first information to the user device 101, and does not affect whether the user device 101 receives or expects to receive the first information.

In step 2103, the ue 101 determines that the first cell does not support reporting the first time information if the first information is not received.

In some embodiments, if the network device 102 sends the first information to the user device 101, the user device 101 may determine that the first cell supports reporting the first time information, otherwise, if the network device 102 does not send the first information to the user device 101, the user device 101 does not receive the first information, and determines that the first cell does not support reporting the first time information.

In some embodiments, the coverage of the network device 102 comprises a first cell, which re-establishes a previously connected cell for the user device 101.

In some embodiments, the ue 101 performs connection reestablishment, one NTN cell is connected before the ue 101 reestablishes, one NTN cell is connected after the ue 101 reestablishes, the first cell is an NTN cell connected between the ue 101 reestablishes, the network device 102 does not send first information to the ue 101, and the ue 101 determines that the first cell does not support the ue 101 to report the first time information if the ue 101 does not receive the first message.

In some embodiments, the coverage of the network device 102 includes a first cell, which is the source cell for the handover of the user equipment 101.

In some embodiments, the ue 101 performs handover, the source cell for handover of the ue 101 is an NTN cell, and the target cell for handover is an NTN cell, the first cell is the source cell of the ue 101 is an NTN cell, the network device 102 does not configure the ue 101 to report first time information to the first cell through broadcast or RRC dedicated signaling, and it is determined that the first cell does not support reporting of the first time information by the ue 101.

For example, the source NTN cell does not configure the UE to report the first time through broadcast or RRC dedicated signaling, and determines that the source NTN cell does not support reporting the first time.

It should be noted that, when the first cell is a TN cell, the user equipment 101 does not report the first time information to the TN cell, and does not need to determine whether the first cell supports reporting the first time information.

Step 2104, the network device 102 sends second information, where the second information is used to configure the ue 101 to report the first time information to the second cell.

In some embodiments, the second information is carried by handover signaling.

In some embodiments, the second information is carried by at least one of a broadcast message, a system message, or a radio resource control, RRC, message.

Step 2105, the ue 101 determines that the second cell supports reporting the first time information when receiving the second information.

In some embodiments, if the network device 102 sends the second information to the user device 101, the user device 101 may determine that the second cell supports reporting the first time information, otherwise, if the network device 102 does not send the second information to the user device 101, the user device 101 does not receive the second information, and determines that the second cell does not support reporting the first time information.

In some embodiments, the coverage of the network device 102 comprises a second cell, which is the cell connected after the user equipment 101 has been re-established.

In some embodiments, the ue 101 performs connection reestablishment, one NTN cell is connected before the ue 101 reestablishes, one NTN cell is connected after the ue 101 reestablishes, the second cell is an NTN cell connected after the ue 101 reestablishes, and the network device 102 configures the ue 101 to report first time information to the second cell through broadcasting or RRC dedicated signaling, so as to determine that the second cell supports the ue 101 to report the first time information.

For example, the NTN cell configures the UE to report the first time through broadcast or RRC dedicated signaling, and determines that the NTN cell supports reporting the first time or the first time window.

In some embodiments, the coverage of the network device 102 includes a second cell, which is the target cell for handover of the user equipment 101.

In some embodiments, the ue 101 performs handover, the source cell for handover of the ue 101 is an NTN cell, the target cell for handover is an NTN cell, the second cell is an NTN cell for handover of the ue 101, and the network device 102 configures the ue 101 to report the first time information to the second cell through a handover command, so as to determine that the second cell supports supporting the ue 101 to report the first time information.

For example, the base station of the target cell sends a handover command to the UE, the UE is configured to report a first time or a first time window in the handover command, and it is determined that the target NTN cell supports reporting the first time or the first time window, specifically, the base station of the target cell sends the handover command to the base station of the source cell, and the base station of the source cell forwards the handover command to the UE.

In some embodiments, the user equipment 101 sends the first time information if a preset condition is met, where the preset condition is: the method comprises the steps that UE is connected with a first cell before connection reestablishment, the UE is connected with a second cell after reestablishment, the first cell and the second cell are non-ground network NTN cells, wherein first time information is carried by first signaling, the first signaling is connection reestablishment completion information, the first cell supports reporting, and the second cell supports reporting of the first time information.

In other words, in the case where connection reestablishment occurs for the ue 101, and the NTN cell connected before the connection reestablishment of the ue 101 does not support the time required for reporting the ue 101 to make the first measurement, and the NTN cell reestablished by the ue 101 supports the time required for reporting the ue 101 to make the first measurement, the ue 101 reports the first time or the first time window in the connection reestablishment completion message.

For example, the UE performs connection reestablishment, and the NTN cell connected before the UE reestablishes does not support reporting the first time, and the NTN cell reestablished by the UE supports reporting the first time, and then the UE reports the first time through the RRC reestablishment completion message.

In some embodiments, the preset conditions are: the method comprises the steps that UE is connected with a first cell before connection reestablishment, the UE is connected with a second cell after reestablishment, the first cell is a terrestrial network TN cell, the second cell is a non-terrestrial network NTN cell, first time information is carried by a first signaling, the first signaling is a connection reestablishment completion message, and the second cell supports reporting of the first time information.

In other words, when the ue 101 performs connection reestablishment, the ue 101 is connected to a TN cell before the connection reestablishment, and the NTN cell reestablished by the ue 101 supports reporting a time required for the ue 101 to perform GNSS measurement, the ue 101 reports a first time or a first time window in a connection reestablishment completion message.

For example, when the UE performs connection reestablishment, the UE is connected to one TN cell before reestablishment, and the NTN cell reestablished by the UE supports reporting the first time, the UE reports the first time through an RRC reestablishment completion message.

Further, in some embodiments, the user equipment 101 sends the first time information when a preset condition is met, where the preset condition is: the method comprises the steps that UE is switched, the UE is connected with a first cell before being switched, the UE is connected with a second cell after being switched, the first cell and the second cell are non-ground network NTN cells, wherein first time information is carried by first signaling, the first signaling is a connection reconfiguration completion message or a switching completion message, the first cell does not support reporting of the first time information, and the second cell supports reporting of the first time information.

In other words, when the ue 101 performs handover, and the source cell of the handover is an NTN cell that does not support the time required for reporting the GNSS measurement by the ue 101, and the target cell of the handover is an NTN cell that supports the time required for reporting the GNSS measurement by the ue 101, the ue 101 reports the first time or the first time window in the connection reconfiguration complete message.

For example, when the UE performs handover, and the source cell of the handover is an NTN cell that does not support reporting the first time or the first time window, and the target cell of the handover is an NTN cell that supports reporting the first time or the first time window, the UE reports the first time or the first time window through an RRC reconfiguration complete message (i.e., a handover complete message).

In some embodiments, the user equipment 101 sends the first time information if a preset condition is met, where the preset condition is: the method comprises the steps that UE is switched, the UE is connected with a first cell before being switched, the UE is connected with a second cell after being switched, the first cell is a terrestrial network TN cell, the second cell is a non-terrestrial network NTN cell, wherein first time information is carried by a first signaling, the first signaling is a connection reconfiguration completion message or a switching completion message, and the second cell supports reporting of the first time information.

In other words, when the ue 101 performs handover, and the source cell of the handover is a TN cell, and the target cell of the handover is the time required for supporting reporting of the GNSS measurement by the ue 101, the ue 101 reports the first time or the first time window in the connection reconfiguration complete message.

For example, when the UE switches, and the source cell of the switching is a TN cell, and the target cell of the switching is an NTN cell supporting reporting of the first time or the first time window, the UE reports the first time or the first time window through an RRC reestablishment completion message. In some embodiments, step 2101 may be implemented as a stand-alone embodiment.

In some embodiments, steps 2102 and 2013 and 2105 are performed, with steps 2102 and 2013 and an alternative method for determining that the first cell does not support reporting the first time information.

In some embodiments, steps 2104 and 2014 and 2015 are performed, and steps 2104 and 2015 are an alternative method of determining that the second cell supports reporting the first time information.

In some embodiments, steps 2101-2015 are performed, where steps 2102 and 2103 are performed first or steps 2104 and 2105 are performed first, i.e., determining that the first cell does not support reporting the first time information and determining that the second cell supports reporting the order of the first time information, which is not limited in this disclosure.
