Problems solved by technology

Since the cell information of the dual connection with the UE cannot be recorded at the same time, it is impossible to accurately estimate the UE's mobility status, so the parameter configuration of the UE in the target cell is not the most ideal configuration, especially when the dual connection cannot be realized or the network decides not to connect the UE When configured in dual connection mode

Embodiment Construction

[0022] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0023] Generally, the UE history information includes information about a corresponding cell that the UE has visited, and the corresponding cell refers to a cell before the target cell and in which the UE is in an active state. UE history information also includes: a list of last visited cells (Last Visited Cell List) and past visited cell information (Last Visited CellInformation), where the past visited cell information includes global cel...

Abstract

The invention provides a method for managing historical information of user equipment of a double-connection system. The method comprises the following steps: collecting and storing historical information of user equipment, wherein the historical information includes cell information of a main base station as a main cell and cell information of an auxiliary base station as an auxiliary cell; and storing the information of the main cell and the information of the auxiliary cell in a last visited cell list and last visited cell information in the historical information in the form of independent cells. Complete recording of the historical information of the user equipment is realized, the mobility state / speed of the user equipment can be estimated accurately, and thus, optimized configuration can be carried out on the whole network.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically relates to a mechanism for user equipment history information in a dual connectivity system. Background technique [0002] In the network, the historical information of the UE (User Equipment, UE) can be used to estimate the mobile speed / state of the UE, which is very useful for the network to set parameters related to mobility management such as handover, because mobility performance is closely related to Depends on the settings of these parameters. The corresponding parameters can be optimized for users with different speeds. In addition, in the prior art Mobility State Estimation (Mobility State Estimation, MSE), the estimation accuracy of the mobility state in the heterogeneous network is not as accurate as that in the homogeneous network with only macro cells. In addition, in the current RAN2 standardization of 3GPP, it is considered beneficial ...
