Embodiment Construction

[0062] The invention provides a mobile state estimation enhancement method and device based on handover type specific weight. In order to better understand the technical solution of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] see figure 1 , figure 1 It is a flow chart of the first embodiment of the mobile state estimation enhancement method provided by the embodiment of the present invention.

[0064] Step A1. Obtain the time point when the mobile terminal transitions to the RRC-CONNECTED state and the motion state of the mobile terminal before initialization.

[0065] Specifically, when the mobile node changes from the IDLE state to the CONNECTED state, it will notify the base station through uplink signaling, and the mobile state estimation unit at the base station side will use this time point as the starting point of the handover history record of the mo...

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...
