s102, receiving a ue capability information restriction response message from the network, where the ue capability information restriction response message is determined based on the negotiation process of the at least two base stations, and is used to instruct the at least two base stations to accept or reject the ue capability information restriction request.

In some embodiments, the limited available capability information is a subset of the capability information reported by the user equipment upon initial registration with the network.

In some embodiments, before sending the user equipment capability information restriction request, the method further comprises: sending indication information of user equipment capability information limitation to the network; and receiving a user equipment capability information inquiry request sent by the network, wherein the user equipment capability information inquiry request is generated based on the indication information of the user equipment capability information limitation. That is, in some embodiments, the ue triggers the action of sending the ue capability information restriction request after receiving the ue capability information query request from the network. In some embodiments, the ue may also directly send the ue capability information restriction request to the network. It should be noted that, in the embodiment of the present invention, the ue capability information restriction request refers to a message that includes the capability information of the ue after restriction.

And when the result of the negotiation process is that the updating request limited by the user equipment capability information is refused, the second base station does not carry out resource reconfiguration.

In some embodiments, when the ue capability information restriction request is received directly from the ue, the ue may send the capability information restriction request upon establishing an RRC connection with the first base station, when the ue capability information restriction request is received based on an RRC connection establishment request message. In some embodiments, the ue may also send the capability information restriction request after establishing RRC connection with the first base station, where the ue capability information restriction request is received based on other RRC signaling, for example, a ue capability restriction request message.
