Description

Communication method and related equipment Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and related devices. Background Dual connectivity (dual connectivity, DC) is a unique technology in 5G wireless systems, allowing a terminal device (UE) to have the capability to establish connectivity with two base stations simultaneously. The purpose of using dual connectivity is to enhance network performance by combining the resources of different base stations, thereby improving data rate, reducing delay, and improving overall quality of service. In dual connectivity, two base stations, one of which is a Master Node (MN), also called a master node, and the other of which is a Secondary Node (SN), also become secondary nodes. Under the primary base station, there is a primary cell called primary cell (PRIMARY CELL, pcell) and other cells, and the UE is randomly accessed to Pcell, and these cells together form a primary cell group (MASTER CELL group, MCG), as shown in fig. 1. Under the secondary base station there is a primary cell called primary secondary cell (primary secondary cell, PScell) and other cells, which together form a primary secondary cell group (secondary cell group, SCG) by random access PScell for the UE, as shown in fig. 1. When LTM switching is executed between the master base stations MN, one or more candidate master base stations pre-configure configuration information about themselves, the configuration information is sent to the original master base station, and the original master base station sends the configuration information to the UE through a radio resource control (Radio Resource Control, RRC) reconfiguration message. The configuration information may further include a processing instruction of each candidate MN for the SCG configuration information, for example, releasing the SCG configuration information or maintaining the SCG configuration information unchanged. After receiving the LTM switching command, the UE switches to the target MN, and determines to release SCG configuration information or maintain the SCG configuration information according to the processing instruction of SCG configuration under the target MN. After releasing the SCG configuration information, i.e. the UE enters a non-dual connectivity state, while maintaining the SCG configuration information, i.e. the UE continues to maintain the dual connectivity state. When performing a continuous inter-MN handoff, such as when switching to MN1 for the first time, processing for SCG configuration information under MN1 is to release SCG configuration information, and when switching to MN2 for the second time, processing for SCG configuration information under MN2 is to maintain SCG configuration information. Since the UE releases the SCG configuration information when switching for the first time, that is, the UE is in a non-dual connection state, and instructs to maintain the SCG configuration information when switching to MN2, the UE and the network side understand inconsistent, which will cause the UE/network to make the next execution action unclear. Disclosure of Invention The application provides a communication method and related equipment, which are used for realizing that UE (user equipment) can respond to processing operation of a switched main base station aiming at SCG (configuration information) in time and ensuring normal communication between the UE and the main base station. In order to achieve the above object, the present application provides the following technical solutions: In a first aspect, the application provides a communication method, which is applied to a first main base station, and comprises the steps of sending first information to one or more second main base stations, wherein the first information is used for triggering the second main base stations to determine processing operation of configuration information aiming at auxiliary base stations, the second main base stations are candidate main base stations, receiving second information sent by the second main base stations, the second information comprises the configuration information of the second main base stations corresponding to the auxiliary base stations and/or the processing operation aiming at the configuration information, and sending third information to terminal equipment, and the third information comprises the second information, so that the terminal equipment can execute corresponding communication strategies according to the processing operation aiming at the configuration information after being switched from the first main base station to the second main base station. According to the scheme, the original master base station connected with the terminal equipment, namely the first master base station, sends first information to each candidate master base station (second master base station) in a switching preparation stage, and t
