Method of reporting auxiliary information, method of configuration, terminal and network-side devices [Reference to related applications] This application claims priority to application No. 201910755723.5, filed with the Chinese Intellectual Property Office on August 15, 2019, and incorporates the entire contents thereof by reference into this application. [Technology Field] The present disclosure relates to the field of communication technology, and in particular to a method for reporting auxiliary information, a method for configuring, a terminal, and a network-side device. A terminal can establish connections with two cells or two groups of cells simultaneously, which is Dual Connectivity (DC). In the Dual Connectivity mobility process, the terminal can maintain connections with both the source cell and the target cell simultaneously, and then the terminal can disconnect from the source cell and maintain connections only with the target cell. Currently, there is no clear solution yet regarding how the terminal reports auxiliary information in Dual Connectivity application scenarios. In order to explain the technical solution according to the embodiment of the present disclosure more clearly, the drawings to be used in describing the embodiment of the present disclosure are briefly introduced below. The drawings in the following description are merely some embodiments of the present disclosure, and it is obvious to those skilled in the art that other drawings can be obtained from these drawings without performing creative work. Figure 1 is a schematic diagram of a dual-connection mobility process. FIG. 2 is a structural diagram of a network system provided by an embodiment of the present disclosure. FIG. 3 is a flowchart of a method for reporting auxiliary information applied to a network system provided by an embodiment of the present disclosure.
