Dual-connectivity switching enhancing method based on mobility state estimate and mobility state estimate device

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 mobile state estimation-based dual connection user switching enhancement method and estimation device. 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 inter-cell resource coordination, more frequent handover and more complex channel environment, etc. To address the challenges in heterogeneous networks mentioned above. In the research process of the micro-cell enhancement technology, a dual-connectivity (Dual-Connectivity) technology is proposed. The so-called dual connection means that the terminal is connected to two nodes of Macrocell and Smallcell at the same time in the common coverage area of ​​Macrocell and smallcell. MeNB serves as the signaling anchor...
