Currently, in a dual-connection scenario, a conditional Secondary cell addition (CPA, conditional PSCell Addition) is that a Master Node (MN) of a network side device configures information such as cell identifiers of one or more candidate pscells and events corresponding to the conditional addition to a terminal in advance, and when the terminal evaluates that a candidate target primary Secondary cell (PSCell, PRIMARY AND Secondary Cells) cell meets a condition, the cell is added as a PSCell. Similarly, the Conditional Secondary cell change (CPC) PSCELL CHANGE is a primary Node (MN) or a Secondary Node (SN) of the network side device, and configures information such as cell identifiers of one or more candidate pscells and events added by corresponding conditions to the terminal.

Detailed Description

Prior to introducing the technical solution of the embodiment of the present invention, a description will be given of related technology.

In the related art, in a dual-connection scenario, a conditional secondary cell addition (CPA, conditional PSCell Addition) is that a Master Node (MN, master Node) of a network side device configures information such as a cell identifier of one or more candidate pscells, an event (such as one or two events of an A4 or B1 event) corresponding to the conditional addition, a C-RNTI used by a UE in the candidate PSCell, a dedicated random access resource, etc. to the UE in advance, and when the UE evaluates that a certain candidate target PSCell cell satisfies a condition, the cell is added as a PSCell. Similarly, the Conditional secondary cell change (CPC) PSCELL CHANGE is MN or SN of the network side device, configures information such as cell identities of one or more candidate pscells, events (such as A3 and/or A5) added by corresponding conditions, C-RNTI used by the UE in the candidate PSCell, and dedicated random access resources to the UE, and when the UE evaluates that a certain candidate target PSCell cell meets the conditions, initiates a PSCell change procedure, that is, switches from the source PSCell to the target PSCell.

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

first, in one aspect, when the PSCell of the UE successfully performs the CPA or CPC, RLF or MCG Failure of the primary cell PCell may occur quickly (e.g., for a period of time), which may indicate that it may not be necessary for the CPA or CPC to be performed too late.

Second, in another aspect, if the UE performs a PCell handover after the CPA/CPC is triggered, if the target PCell cannot make a dual connection with the new PSCell, the UE cannot make a dual connection with the target PCell, and the previous CPA/CPC is unnecessary.

Third, in one scenario, after configuring the CPA or CPC for the UE, before the CPA or CPC triggers, the UE has a PCell handover or RLF in the PCell, indicating that the CPA or CPC triggers too late or unnecessary.

Based on the CPA, the related information of CPC change of the conditional primary and secondary cells is added to the primary and secondary cells of the reporting condition of the network equipment; wherein the related information of the CPA or CPC comprises one or more of the following: the terminal applies CPA configuration or CPC configuration or first time difference between the moment when the target primary and secondary cells PScell complete connection establishment and the primary cell PCell radio link Failure RLF or the primary cell group MCG Failure; the first time difference is lower than the indication information of the preset duration threshold; the terminal generates indication information that PCell switching occurs after CPA or CPC configuration is applied, and target PCell and new PScell cannot or can not perform double connection; indication information that the terminal has a PCell handover or RLF in the PCell before the CPA or CPC trigger; a second time difference between the configuration of the CPA or CPC and the handover of the PCell or the RLF occurring at the PCell.

It should be noted that the embodiment of the present invention has the following advantages:

(1) Considering that RLF or MCG Failure of the primary cell PCell may occur soon when the PSCell of the UE succeeds in CPA or CPC in the related art, it is explained that it may not be necessary for the CPA or CPC to proceed too late. Therefore, in the embodiment of the present invention, the UE reports a first time difference between the time when the CPA/CPC occurs (or expressed as a configuration of applying the CPA/CPC) or the UE connects 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 duration threshold. In this way, the network side may adjust the event triggering the CPA/CPC and/or the corresponding Threshold (e.g. A3-Offset, A5-Threshold1, A5-Threshold2 in the event of A3, A5) and the time to trigger (TTT, T imeToTrigger) according to the information reported by the UE, so that the CPA/CPC is executed or triggered earlier, or the network side does not configure the CPA or CPC.

(2) Considering that in the related art, if the UE performs a PCell handover after the CPA/CPC is triggered, if the target PCell and the new PSCell cannot perform dual connectivity, the UE cannot perform dual connectivity on the target PCell, the previous CPA/CPC is unnecessary, and if the target PCell and the new PSCell can perform dual connectivity, the CPA/CPC is necessary. Therefore, in the embodiment of the present invention, the UE reports the indication information that the PCell handover occurs after the CPA or CPC configuration is applied, and whether the target PCell and the new PSCell cannot or can not perform dual connectivity. In this way, when judging whether to configure or optimize the CPA/CPC, the network side can acquire information about whether the target PCell and the new PSCell can perform dual connectivity, where the information may be reported to the source base station by the UE, or the node source MN configuring the CPA or the node source MN configuring the CPC or the source SN may be notified by the base station target SN where the target PSCell is located.

(3) Considering that the UE has a PCell handover or RLF in the PCell after the CPA or CPC is configured for the UE in the related art, before the CPA or CPC trigger, it is explained that the CPA or CPC trigger is too late or unnecessary. Therefore, in the embodiment of the present invention, the UE reports the indication information that the UE has PCell handover or RLF occurs in the PCell before the CPA or CPC triggers; or a second time difference between configuration of the CPA or CPC and the PCell or RLF occurring at the PCell, so that the network side adjusts an event triggering the CPA/CPC and/or a corresponding Threshold (e.g., A3-Offset, A5-Threshold1, A5-Threshold2 in the event of A3, A5), the triggering time (TTT, timeToTrigger) so that the CPA/CPC is executed or triggered earlier, or the network side does not configure the CPA or CPC.
