Cell re-selection method, device and system

Abstract

This invention relates to a re-selection method for local areas, a device and a system for reducing call loss of user devices at connection state including: a UE gets the identity information of a base station where an adjacent area locates and selects a local area in the same identity information with the base station where the current local area of the UE locates in priority based on the identity information of the base station, therefore, UE can influence sequence of current and adjacent local areas based on the idnetity information of the base station and retarding parameter of call loss and UE can try its best to select an area belonging to a same base station to respond paging of network as much as possible.

Description

Method, device and system for cell reselection technical field The present invention relates to a cell reselection method and system, in particular to a cell reselection method and system for reducing call loss of connected user equipment. Background technique In the cell reselection process of WCDMA (Wideband Code Division Multiple Access) existing technology, the user terminal completes the measurement of the signal quality of the neighboring cell and the current cell, and uses the R criterion to sort: After the user terminal compares according to a specific criterion (such as the R criterion of UMTS (Universal Mobile Telecommunications System)), the signal of the neighboring cell is better than the cell currently serving the user terminal; when the signal of the neighboring cell is better than the current serving cell of the user terminal Cell signal, and the duration reaches or exceeds Treselection (the duration of the cell reselection timer), the neighboring cell wil...

AI Technical Summary

Problems solved by technology

However, in the process of context transfer, since multiple air interface signalings are involved, the user terminal cannot respond to the paging of the network during the interaction process of these signalings, thus reducing the service connection rate and increasing the Equipment call loss rate in the connection state of the user terminal

In the LTE system, there is currently no relevant technical solution to solve the defect that the user terminal's service connection rate decreases during the context transfer process between different base stations.
