Technical Field

Background technique

At present, in the dual-connection scenario, Conditional PSCell Addition (CPA) is that the master node (MN) of the network side device configures the cell identifiers of one or more candidate PSCells, the corresponding conditional added events and other information to the terminal in advance. When the terminal evaluates that a candidate target primary and secondary cells (PSCell) cell meets the conditions, the cell is added as a PSCell. Similarly, Conditional PSCell Change (CPC) is that the master node (MN) or secondary node (SN) of the network side device configures the cell identifiers of one or more candidate PSCells, the corresponding conditional added events and other information to the terminal. When the terminal evaluates that a candidate target PSCell cell meets the conditions, the PSCell change process is initiated.

Detailed ways

Before introducing the technical solution of the embodiment of the present disclosure, the related technology is first explained.

In the related technology, in the dual connection scenario, Conditional PSCell Addition (CPA) is that the master node (MN) of the network side device configures the cell identifiers of one or more candidate PSCells, the corresponding conditional addition events (such as one or two events of A4 or B1 events), the cell radio network temporary identifier (Cell RNTI, C-RNTI) used by the UE in the candidate PSCell, dedicated random access resources and other information to the terminal device or user terminal (User Equipment, UE) in advance. When the UE evaluates that a candidate target PSCell cell meets the conditions, the cell is added as a PSCell. Similarly, Conditional PSCell Change (CPC) is a network-side device's MN or SN that configures the UE with one or more candidate PSCell cell identifiers, corresponding conditionally added events (such as A3 and/or A5), the C-RNTI used by the UE in the candidate PSCell, dedicated random access resources and other information. When the UE evaluates that a candidate target PSCell cell meets the conditions, the PSCell change process is initiated, i.e., switching from the source PSCell to the target PSCell.

In the related technologies, technical problems existing when UE performs CPA or CPC include:

First, from one aspect, when the UE's PSCell successfully performs CPA or CPC, RLF or MCG Failure of the primary cell PCell may occur soon (e.g. within a certain period of time), which means that performing CPA or CPC too late may be unnecessary.

Second, from another perspective, if the UE switches to PCell after triggering CPA/CPC, if the target PCell and the new PSCell cannot be dual-connected, the UE cannot be dual-connected in the target PCell, and the previous CPA/CPC is unnecessary.

Third, in one scenario, after CPA or CPC is configured for the UE and before CPA or CPC is triggered, the UE switches to PCell or RLF occurs in PCell, which means that CPA or CPC is triggered too late or is unnecessary.

Based on this, in an embodiment of the present disclosure, relevant information of adding CPA to conditional primary and secondary cells or changing CPC to conditional primary and secondary cells is reported to a network device; wherein the relevant information of the CPA or CPC includes one or more of the following: the first time difference between the moment when the terminal applies the CPA configuration or applies the CPC configuration or completes the connection establishment in the target primary and secondary cell PSCell and the primary cell PCell radio link failure RLF or the primary cell group MCG failure Failure; indication information that the first time difference is lower than a preset duration threshold; the terminal undergoes a PCell switch after applying the CPA or CPC configuration, and the target Indication information that the standard PCell and the new PSCell cannot or can be dual-connected; indication information that the terminal has undergone PCell switching or RLF has occurred in the PCell before the CPA or CPC is triggered; a second time difference between the configuration of the CPA or CPC and the switching of the PCell or the occurrence of RLF in the PCell.

It should be noted that the embodiments of the present disclosure have the following advantages:

(1) Considering that in the related art, when the UE's PSCell successfully performs CPA or CPC, the RLF or MCG Failure of the primary cell PCell may occur soon, this means that it may be unnecessary to perform CPA or CPC too late. Therefore, in the disclosed embodiment, the UE reports the first time difference between the time when CPA/CPC occurs (or is expressed as the configuration of applying CPA/CPC) or the time when the UE is connected to the target PSCell and the PCell RLF or MCG Failure, or the UE reports that the first time difference is lower than a certain time threshold. In this way, the network side can adjust the event triggering CPA/CPC and/or the corresponding threshold value (such as a3-Offset, a5-Threshold1, a5-Threshold2 in the events A3 and A5), the trigger time (TimeToTrigger, TTT) according to the information reported by the UE, so that CPA/CPC is executed or triggered earlier, or the network side does not configure CPA or CPC.

(2) Considering that in the related art, if the UE switches PCell after triggering CPA/CPC, if the target PCell and the new PSCell cannot be dual-connected, the UE cannot be dual-connected in the target PCell, and the previous CPA/CPC is unnecessary. If the target PCell and the new PSCell can be dual-connected, then CPA/CPC is necessary. Therefore, in the embodiment of the present disclosure, the UE reports an indication that a PCell switch has occurred after the CPA or CPC configuration is applied, and the target PCell and the new PSCell cannot or can be dual-connected. In this way, when the network side determines whether it is necessary to configure or optimize CPA/CPC, it can obtain information on whether the target PCell and the new PSCell can be dual-connected. This information can be reported to the source base station by the UE, or it can be notified by the base station target SN where the target PSCell is located to the node source MN that configures the CPA or the node source MN or source SN that configures the CPC.

(3) Considering that in the related art, after CPA or CPC is configured for the UE, before CPA or CPC is triggered, the UE switches to PCell or RLF occurs in PCell, it means that CPA or CPC is triggered too late or unnecessary. Therefore, in the embodiment of the present disclosure, the UE reports the indication information that the UE switches to PCell or RLF occurs in PCell before the CPA or CPC is triggered; or the second time difference between the configuration of CPA or CPC and the switching of PCell or the occurrence of RLF in PCell, so that the network side adjusts the event triggering CPA/CPC and/or the corresponding threshold value (such as A3, A5) a3-Offset, a5-Threshold1, a5-Threshold2) and trigger time (TimeToTrigger, TTT) in the event make CPA/CPC executed or triggered earlier, or CPA or CPC is not configured on the network side.
