In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

In some embodiments, in the event that a handover operation (e.g., cell handover) is successful, the terminal may send a successful handover report (Successful HandOver Report) to the network device for the network device to properly learn the network environment of the terminal so that the network device can make the proper configuration of the terminal.

In some embodiments, the SHR may record the measurement result of the measurement of the cell by the terminal, but the measurement result does not include the mobility (L1/L2-TRIGGERED MOBILITY, LTM) related information triggered by layer 1 or layer 2, and for some scenarios, the SHR that does not record the LTM related information has a shortage of effect on the network device, which makes it difficult to ensure that the network device knows the network environment of the terminal properly.

For example, in the LTM scenario, the network device may configure LTM configuration information for the terminal, where the LTM configuration information includes LTM candidate cells (may be one cell or a cell group formed by a plurality of cells), and may also include related information used for communication in the candidate cells.

The network device may then perform LTM cell switching on the terminal, e.g., the network device may instruct the terminal to change cells, e.g., instruct the terminal to change the cell from candidate cell #1 to candidate cell #2, through layer 1 (e.g., through downlink Control information (Downlink Control Information, DCI)) or layer 2 (e.g., through a medium access Control layer Control Element (MAC CE)).

Because the related information used for communication in the candidate cell is preconfigured to the terminal by the network equipment through LTM configuration, the network equipment does not need to configure the related information used for communication in the candidate cell #2 for the terminal after the terminal is switched to the candidate cell #2, and the terminal can complete cell switching and communication as soon as possible.

However, the L3 triggered mobile cell HandOver, such as conventional HandOver (HO), conditional HandOver (CHO), etc., is triggered by radio resource control signaling (Radio Resource Control, RRC) signaling, which is relatively long in time compared with the LTM cell HandOver, and is not beneficial for the terminal to complete the cell HandOver and communication as soon as possible.

In the related art, the terminal may perform LTM cell handover based on LTM configuration information configured by the network device and a handover command transmitted by the network device, however, the SHR in the related art does not include LTM related information, and thus cannot be accurately used in a case where the network device determines that the terminal is related to LTM, so improvement of the SHR transmitted by the terminal to the network device is necessary.

In step S201, the terminal records LTM related information in the SHR.

In step S202, the terminal transmits the SHR to the network device.

In some embodiments, a terminal receives request information sent by the network device, where the request information is used to request the terminal to send the SHR to the network device.

For example, the terminal may transmit the SHR recorded with LTM related information to the network device after receiving the request information transmitted from the network device. The request information may be multiplexed with conventional request information (e.g., a request for acquiring SHR), or the request information may be newly defined request information, which may be dedicated to the requesting terminal to transmit the SHR recorded with LTM related information.

It should be noted that, in some embodiments, the terminal may send the LTM related information to the network device, or may not be performed based on the request information of the network device, for example, the terminal may record the time T1 for determining the LTM related information, and when the request information of the network device is not received within the time range of the duration T1 from T1, the terminal may automatically send the LTM related information (e.g. send the LTM related information on a preconfigured resource) to the network device, thereby being beneficial to avoiding that the LTM related information storage time process of the terminal is deleted, which causes the overhead of the measurement operation to be wasted.

In the embodiment of the disclosure, the terminal records the related information of the LTM in the SHR, so that the related information of the LTM can be sent to the network device according to the requirement or the network device request later, and compared with the case that the terminal records the related information of the traditional switching mode only in the SHR, the SHR recorded with the related information of the LTM can be used for the network device to accurately determine the condition of the related LTM of the terminal, thereby being beneficial to ensuring that the network device can timely and accurately determine whether to perform the LTM according to the SHR reported by the terminal.

It should be noted that in some embodiments, the terminal may also record LTM related information in a radio link failure (Radio Link Failure, RLF) report. For example, in case that the LTM recovery is successful (RLF occurs during the LTM handover, and the access attempt is successful again based on the LTM configuration), the terminal may not perform the operation of recording the LTM related information into the SHR, but record the LTM related information into an RLF report, and may then transmit the RLF report to the network device as needed or in case that the network device requests to acquire the RLF report is received.

In some embodiments, the terminal records LTM related information in the SHR if a first condition is satisfied, wherein the first condition includes at least one of:

The terminal stores LTM configuration information;

the terminal successfully executes switching operation;

The second condition is satisfied.

For example, the switching operation includes at least one of: LTM handoff operation, legacy handoff operation, conditional handoff operation, dual active protocol stack (Dual Active Protocol Stack, DAPS) handoff.

For example, in the case that the terminal stores LTM configuration information, that is, the network device configures the LTM configuration information for the terminal, the terminal has a possibility of performing LTM handover, so that it is necessary to send LTM related information to the network device, so that the network device timely and accurately determines whether to perform LTM on the terminal. Therefore, in this case, the terminal may record the LTM related information in the SHR so that the LTM related information may also be transmitted to the network device when the SHR is transmitted.

For example, in the case that the terminal stores LTM configuration information, that is, the network device configures LTM configuration information for the terminal, the terminal performs LTM handover, it is necessary to send LTM related information to the network device, so that the network device timely and accurately determines whether the LTM configuration and the handover command are reasonable. Therefore, in this case, the terminal may record the LTM related information in the SHR so that the LTM related information may also be transmitted to the network device when the SHR is transmitted.

For example, in the case that the terminal stores LTM configuration information, that is, the network device configures the LTM configuration information for the terminal, the terminal performs other types of handover, such as a conventional handover operation, a conditional handover operation, and a dual-active protocol stack handover, at this time, it is also necessary to send LTM related information to the network device, so that the network device timely and accurately determines whether the current handover decision and the handover configuration are reasonable. Therefore, in this case, the terminal may record the LTM related information in the SHR so that the LTM related information may also be transmitted to the network device when the SHR is transmitted.

In some embodiments, the second condition includes a first timer meeting a threshold condition, wherein the first timer includes at least one of:

A T304 timer;

t310 timer;

t312 timer.

In some embodiments, the second condition may also be referred to as a SHR record trigger condition.

For example, the T304 timer may be used to detect success or failure of a handover, and when the UE receives a handover command, the T304 timer will be started, and if the handover is successful, the T304 timer will be terminated; if the T304 timer expires, a handover failure is indicated.

For the T304 timer, the threshold corresponding to the T304 timer may be indicated to the terminal by the target cell during handover (e.g., the target cell during LTM handover). For example, the T304 timer meeting the threshold condition may include: the ratio of the timing value of the T304 timer to the configuration value of the T304 timer is greater than a T304 threshold percentage, wherein the T304 threshold percentage may be included in a successful handover configuration received before a last synchronized reconfiguration is performed, the configuration value of the T304 timer may be included in a last applied RRC reconfiguration message, and the RRC reconfiguration message may include a synchronized reconfiguration.

I.e. the ,the ratio between the value of the elapsed time of the timer T304 and the configured value of the T304 timer,included in the last applied RRCReconfiguration message including the reconfiguration With Sync,is greater than thresholdPercentageT304 if included in the successHO-Config received before executing the last reconfiguration with sync.

For example, the T310 timer may be used to monitor radio link failure, and the terminal may start the T310 timer when detecting a physical layer failure, and stop the T310 timer before the T310 timer expires if the terminal detects a physical layer failure recovery, or triggers a handover procedure, or the terminal initiates a connection reestablishment procedure. After the T310 timer is overtime, if the security mode is not activated, the terminal enters an RRC_IDLE (IDLE) state; otherwise, triggering RRC connection reestablishment flow.

For the T310 timer, the threshold corresponding to the T310 timer may be indicated to the terminal by the source cell during handover (e.g., the source cell during LTM handover). For example, the T310 timer meeting the threshold condition may include: the ratio of the timing value of the T310 timer to the configuration value of the T310 timer is greater than a T310 threshold percentage, wherein the T310 threshold percentage may be included in being configured by the source primary cell prior to performing the reconfiguration of the last synchronization and the configuration value of the T310 timer may be configured when connected to the source primary cell prior to the terminal performing the reconfiguration of the last synchronization.

I.e. the ,the ratio between the value of the elapsed time of the timer T310 and the configured value of the timer T310,configured while the UE was connected to the source PCell before executing the last reconfiguration with sync,is greater than thresholdPercentageT310 included in the successHO-Config if configured by the source PCell before executing the last reconfiguration with sync.

For example, the T312 timer functions similarly to the T310 timer, but the timeout period of the timer may be different so that the reconstruction process may be triggered faster when the T312 timer is used than when the T310 timer is used to accelerate the RLF recovery process.

For the T312 timer, the threshold corresponding to the T312 timer may be indicated to the terminal by the source cell during handover (e.g., the source cell during LTM handover). For example, the T312 timer meeting the threshold condition may include: the ratio of the timing value of the T312 timer to the configuration value of the T312 timer is greater than a T312 threshold percentage, wherein the T312 threshold percentage may be included in the configuration by the source primary cell prior to performing the final synchronized reconfiguration and the configuration value of the T312 timer may be configured when connected to the source primary cell prior to the terminal performing the final synchronized reconfiguration.

I.e. the ,the ratio between the value of the elapsed time of the timer T312 and the configured value of the timer T312,configured while the UE was connected to the source PCell before executing the last reconfiguration with sync,is greater than thresholdPercentageT312 included in the successHO-Config if configured by the source PCell before executing the last reconfiguration with sync.

It should be noted that, the first timer may be a conventional timer, such as T304, T310, and T312 described above, or may be a newly defined timer, which may be dedicated to the LTM handover type and specific to a specific one or more LTM candidate cells. While the logic for the newly defined timer to satisfy the threshold condition may be similar to that of a conventional timer, wherein the threshold percentages involved may be the same or different, and this disclosure is not repeated.

It should be noted that, the first timer meeting the threshold condition may be determined based on a common threshold condition, that is, without distinguishing the type of handover performed by the terminal, or may be dedicated to the terminal to record the LTM related information into the SHR, and determine whether the second condition is met, which may be configured for one or more LTM candidate cells, or may be configured for common usage of all LTM candidate cells, which will not be repeated in the present disclosure.

In some embodiments, the LTM related information includes at least one of:

information of at least one cell;

Time information indicating a time interval (e.g., TIMESINCELTM-Reconfig-r 18) from receiving LTM configuration information to performing an LTM handover operation by the terminal.

In some embodiments, the information of the at least one cell includes at least one of:

Identification information of a cell (e.g., cell ID);

a measurement result corresponding to the cell;

and indicating information corresponding to the cells, wherein the indicating information is used for indicating whether the corresponding cells are LTM candidate cells.

In some embodiments, the cell comprises at least one of: a source cell, a target cell, a serving cell, a neighbor cell, one or more LTM candidate cells.

The identification information of the cells and the measurement results of the cells may have an association relationship, and accordingly, the terminal may determine the measurement results of the terminal in at least one cell according to the LTM related information in the SHR.

In some embodiments, the indication information corresponding to the cell may be 1-bit LTM indication information, which is used to indicate whether the SHR recorded cell is an LTM candidate cell. For example, 0 indicates that the cell is not an LTM candidate cell, 1 indicates that the cell is an LTM candidate cell, or 1 indicates that the cell is not an LTM candidate cell, 0 indicates that the cell is an LTM candidate cell, or the presence of the LTM indication information indicates that the cell is an LTM candidate cell, and the absence indicates that the cell is not an LTM candidate cell.

It should be noted that, the present disclosure may also be implemented in other manners to indicate whether the corresponding cell is an LTM candidate cell, and is not limited to the above indication by the LTM indication information, and the specific indication manner may be determined according to needs, which is not limited to this disclosure.

In some embodiments, the terminal may record, in the SHR, identification information of one or more neighboring cells and corresponding measurement results, where each neighboring cell corresponds to LTM indication information, where the LTM indication information is used to indicate whether the corresponding neighboring cell is an LTM candidate cell.

In some embodiments, the indication information corresponding to the cell may be a specific list, where the list includes at least one of identification information of the cell and measurement results corresponding to the cell, and the list may characterize that the cell corresponding to the information in the list is an LTM candidate cell.

In some embodiments, the operations performed by the terminal on the cell include at least one of: minimization of drive tests (Minimization DRIVE TEST, MDT), self-organizing networks (Self-Organizing Network, SON).

In some embodiments, the terminal may measure signals in a beam (beam) of the network device, for example, may measure synchronous broadcast signal blocks (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB) in the beam, and of course, the measured signals may not be limited to measuring SSB, may also measure other signals, for example, channel state Information (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS), and the like, which embodiments of the disclosure are not limited.

In some embodiments, the cell-corresponding measurements may include measurements corresponding to one or more SSBs of the candidate cells of the LTM configuration information.

After the network device sends the LTM configuration information to the terminal, some resources need to be reserved for the terminal, so that the terminal can smoothly switch in the LTM candidate cell when the terminal is triggered to perform LTM switching.

However, if the resources are reserved for the terminal for a long time, the resources cannot be used by other terminals for a long time, and the resources are wasted to a certain extent.

According to this embodiment, the network device may determine, according to the time information, whether a time interval from receiving the LTM configuration information to performing the LTM switching operation by the terminal is too long (e.g., the time interval is greater than the interval threshold, it may be determined that the time interval is too long), and then may adjust the LTM configuration information if the time interval is too long.

For example, the time interval from receiving the LTM configuration information to performing the LTM handover operation is greater than the interval threshold, and the network device may adjust the LTM configuration information subsequently sent to the terminal, for example, to reduce LTM candidate cells, which is beneficial to avoiding resource waste caused by long-term reservation of resources for the terminal.

It should be noted that, whether the network device adjusts the LTM configuration information according to the time information, and how to adjust the LTM configuration information, may be implemented based on a policy of the network device itself, or based on a protocol convention, or may be indicated by a core network function module (e.g., an access mobility management function (ACCESS AND Mobility Management Function, AMF)) or an operation maintenance management (Operation Administration AND MAINTENANCE, OAM).

In some embodiments, the measurement includes at least one of: layer1 (Layer 1, L1) measurements; layer 3 measurement results. The measurement result may multiplex the existing resources or may be a newly introduced independent field, which is not limited in this disclosure.

For example, when the terminal measures a signal in a cell, the signal may first be filtered by a layer 1 filter to obtain a layer 1 measurement result. The layer 1 measurement may then be input to a layer 3 filter, which filters to obtain a layer 3 filter result.

For example, the relevant parameters of the layer 1 filter may be determined based on the terminal implementation specific (UE implementation specific).

For example, the relevant parameters of the layer 3 filter may be determined based on parameters (RRC configures parameters) of the radio resource control signaling (Radio Resource Control, RRC) configuration.

For example, the measurement result corresponding to the cell may include only the measurement result of L1; for example, the measurement results corresponding to the cells may include the measurement results of L1 and the measurement results of L3. For example, the measurement result corresponding to the cell may include only the measurement result of L3.

In some embodiments, where the measurement result corresponding to the cell includes only the measurement result of L1, the measurement result corresponding to the cell may be used for at least one of the following by the network device decision: whether LTM is performed, how (e.g., at which time-frequency resources) LTM is performed.

In some embodiments, where the cell-corresponding measurements include L1 measurements and L3 measurements, the cell-corresponding measurements may be used for at least one of the following network device decisions: the LTM is also performed, whether a handover based on L3 measurements is performed (e.g., legacy HO, CHO, etc.), how the LTM is performed (e.g., at which time-frequency resources), how the handover based on L3 measurements is performed (e.g., at which time-frequency resources).

In some embodiments, where the measurement results corresponding to the cell include only measurement results of L3, the measurement results corresponding to the cell may be used for at least one of the following network device decisions: whether it is reasonable to perform a handover based on the L3 measurement results, whether LTM is also required.

As for the measurement result corresponding to the cell, the measurement result specifically includes the measurement result of L1, or includes the measurement result of L3, or includes the measurement result of L1 and the measurement result of L3, which may be indicated by the network device or may be agreed by the protocol.

In some embodiments, the layer 1 and layer 3 measurements may be measurements for the same cell (e.g., layer 1 measurement is a layer 1 measurement for cell #1, layer 3 measurement is a layer 3 measurement for cell # 1).

In some embodiments, the layer 1 and layer 3 measurements may be measurements for different cells (e.g., layer 1 measurement is a layer 1 measurement for cell 1, layer 3 measurement is a layer 3 measurement for cell # 2).

As to whether the layer 1 measurement result and the layer 3 measurement result are measurement results for the same cell or measurement results for different cells, the terminal may be determined based on a network device indication or a protocol convention, which is not limited in this disclosure.

In some embodiments, since the layer 1 measurement result includes a physical layer measurement result, when the terminal sends the SHR to the network device through RRC signaling, the terminal may first perform internal interaction, for example, acquire the layer 1 measurement result from the physical layer through the RRC layer, so as to send the SHR including the layer 1 measurement result to the network device through RRC signaling.

In some embodiments, the terminal sends capability information to the network device, wherein the capability information is used to indicate at least one of:

whether the terminal supports recording the LTM related information in the SHR;

whether the terminal supports sending the SHR to a network device.

In some embodiments, the terminal informs the network device of the supporting situation of recording the LTM related information, recording the LTM related information in the SHR, and transmitting the SHR recorded with the LTM related information to the network device, so that the network device can perform appropriate operations subsequently, which is beneficial to avoiding resource waste.

For example, the terminal supports recording the LTM related information in the SHR and transmitting the SHR to the network device, and the capability information the terminal transmits to the network device may indicate that the terminal supports recording the LTM related information in the SHR and transmitting the SHR to the network device.

In this case, the network device may choose to transmit request information to the terminal to request the terminal to transmit SHR containing LTM related information to the network device when the LTM related information is required.

For example, the terminal supports recording the LTM related information in the SHR but does not support transmitting the SHR to the network device, and the capability information of the terminal transmitted to the network device may indicate that the terminal supports recording the LTM related information in the SHR but does not support transmitting the SHR to the network device.

In this case, when the LTM related information is required, the network device may choose to send request information to other devices capable of communicating with the terminal, so as to request the other devices to obtain SHRs containing the LTM related information from the terminal, and further obtain SHRs containing the LTM related information from the other devices.

For example, the terminal does not support recording the LTM related information in the SHR but supports transmitting the SHR to the network device, and the capability information transmitted by the terminal to the network device may indicate that the terminal does not support recording the LTM related information in the SHR but supports transmitting the SHR to the terminal of the network device.

In this case, since the terminal does not record the LTM related information in the SHR, the network device does not have to attempt to acquire the LTM related information recorded by the terminal by requesting the SHR from the terminal.

In some embodiments, the terminal may choose to record the LTM related information in the SHR related reporting variable, e.g., in reporting variable VarSuccessHO-Report, before recording the LTM related information in the SHR.

Of course, before the terminal records the LTM related information in the SHR, the LTM related information is not limited to being recorded by a reporting variable, but may be recorded by other means, and the disclosure is not limited thereto.

In some embodiments, the SHR used for recording LTM related information may be multiplexed with existing SHRs, SHRs may be newly defined, dedicated to recording LTM related information; in some embodiments, the SHR related reporting variable used to record LTM related information may be multiplexed with existing SHR related reporting variables (e.g., varSuccessHO-Report), and SHR related reporting variables may be newly defined, dedicated to recording LTM related information.

In some embodiments, when the terminal sends the SHR with the LTM related information recorded to the network device, the terminal may further indicate to the network device an identity of an LTM candidate cell (e.g., an identity of an available LTM candidate cell), and the network device may determine the LTM candidate cell according to the identity of the LTM candidate cell, and may forward (forward) the SHR sent by the terminal to the LTM candidate cell.

In some embodiments, the terminal may further send availability indication information to the network device, wherein the availability indication information is used to indicate at least one of: the terminal has stored therein available LTM related information, available LTM candidate cells (e.g., an identification indicating LTM candidate cells). Accordingly, the network device determines which LTM candidate cells are available and/or determines whether available LTM related information is stored in the terminal.

In some embodiments, the availability indication information may multiplex legacy availability indication information; the newly defined availability indication information may also be dedicated to indicating that the terminal has stored therein available LTM related measurements and/or available LTM candidate cells.

In addition, in some embodiments, the report for recording LTM related information is not limited to SHR (e.g., legacy SHR or newly defined SHR), but may also record LTM related information through other reports, such as legacy SON reports (e.g., legacy RLF reports, legacy CEF reports, etc.), legacy MDT reports, etc.; but may also be a newly defined report, such as a newly defined SON report (e.g., a newly defined RLF report, a newly defined CEF report, etc.), such as a newly defined MDT report.

The communication method according to the embodiment of the present disclosure may include at least one of step S201 to step S202. For example, step S201 may be implemented as a separate embodiment, step S202 may be implemented as a separate embodiment, and step s201+s202 may be implemented as a separate embodiment, but is not limited thereto.

In some embodiments, step S201 may be performed in exchange for or concurrently.

In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
