Detailed Description
The inventors noted during the course of the invention that:
after the network receives the MCG Failure Information message, it can decide to send an RRC reconfiguration message (RRC reconfiguration message), an RRC release message (RRC release message), or a mobile from nrcommand (from NR; NR: new Radio) or a mobile from terrestrial Radio access (Evolved Universal Terrestrial Radio Access) message including synchronous reconfiguration to the UE according to the failure cause and measurement result reported by the UE. After the UE receives the RRC reconfiguration or mobilityFromNRCommand, mobilityFromEutraCommand message, the UE will stop the T316 timer, perform an RRC release procedure or perform a handover procedure to restore the MCG-side connection of the UE. When the MCG side trigger MCG failure information reports, if the UE is configured with CPC (conditional PSCell handover, conditional PSCell change; PSCell: primary SCG Cell in secondary Cell group), the UE will stop evaluating CPC.
The main idea of CPC is to download the synchronization reconfiguration information of the spring to the UE in advance for the network side, after the UE receives the reconfiguration of the condition, the UE does not execute the PSCell change immediately like the conventional PSCell change (PSCell switch), but saves the received configuration, measures and evaluates the configured candidate cells until the cell meeting the execution condition of CPC configuration exists, then the UE executes the stored reconfiguration message corresponding to the cell to perform the corresponding PSCell change process, that is, completes the downlink synchronization and triggers the random access process to access the target PSCell, and the network side can configure a plurality of target cells for the UE, so that the UE can select a suitable target cell to complete the corresponding synchronization reconfiguration process under the condition of meeting the condition according to the actual condition of the UE.
The prior art already supports the MCG fast recovery technology and the CPC technology, but there is no technical solution for how to handle CPC after the radio link failure of MCG occurs.
Based on the above, the technical solution provided by the embodiment of the present invention is to solve the problem of how to process the two when they occur simultaneously.
The following describes specific embodiments of the present invention with reference to the drawings.
In the description process, the description will be made from the implementation of the UE and the base station, respectively, and then an example of the implementation of the cooperation between the UE and the base station will be given to better understand the implementation of the solution given in the embodiment of the present invention. Such a description does not mean that the two must be implemented cooperatively or separately, and in fact, when the UE and the base station are implemented separately, they solve the problems of the UE side and the base station side, respectively, and when the two are used in combination, a better technical effect is obtained.
