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] Hereinafter, preferred embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] Generally, the UE history information contains information about the 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. The UE history information also includes: Last Visited Cell List and Last Visited Cell Information, where the past visited cell information includes Global Cell ID and Cell Type , UE s...

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, to a mechanism for user equipment history information of a dual-connection system. Background technique [0002] In the network, the historical information of User Equipment (UE) can be used to estimate the moving speed / status of the UE, which is very useful for network setting and mobility management such as handover related parameters, because the mobility performance closely It depends on the settings of these parameters. The corresponding parameters can be optimized for users with different speeds. In addition, in the Mobility State Estimation (MSE) of the prior art, the accuracy of the estimation of the mobility state in a heterogeneous network is not as accurate as the estimation of the mobility state in a homogeneous network with only macro cells. In addition, in the current 3GPP RAN2 standardization, it is considered beneficial to provide mobile ...
