Dual connectivity handover enhancement method and estimation device based on mobile state estimation

Abstract

The invention provides a dual-connectivity user switching enhancing method based on mobility state estimate MSE, and relates to the technical field of mobile communication. According to the method, the times of macro cell switching carried out by mobile terminals in support of a dual-connectivity technique within the sliding window time of 30s is taken as the basis for mobility state estimate, and the current moving states of users are judged; macro cell switching parameters and micro cell adding, releasing and switching criterions for configuring the dual-connectivity users are sent based on the states; and when the moving states of the mobile terminals are changed, a base station side modifies the switching configurations of the mobile terminals through the MeasConfig information units of an RRC connection reconfiguration message. According to the method, the estimate accuracy of the mobility state of the users for the base station is improved, the signaling cost of high speed users is reduced, the duration of keeping a dual-connectivity state by middle and normal speed users is increased, and moreover, the switching success rate of the dual-connectivity users is further improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a dual-connection user handover enhancement method and estimation device based on mobility state estimation. Background technique [0002] With the densification of the network, the heterogeneous network also brings various challenges to the mobile communication system while maximizing the utilization of the licensed spectrum, including: more complex resource coordination between cells, more frequent handover and more complex channel environment, etc. To address the challenges in the above heterogeneous networks. The Dual-Connectivity technology is proposed in the research process of microcell enhancement technology. The so-called dual connectivity means that the terminal is connected to the macro cell and the small cell in the common coverage area of ​​the macro cell and the small cell at the same time. The MeNB serves as the signaling anchor, and the ...
