Method and device for cell selection

Abstract

The invention discloses a method and device for cell selection and relates to the technical field of wireless communication, for the purposes of enabling user equipment to be more accurately connected with a cell capable of providing a service so as to complete a service process when the user equipment initiates the service or performs handover, reducing the signaling overhead load of a network side and improving user experience. The method comprises the following steps: obtaining service types of cell services and signal quality corresponding to cells; and selecting at least one cell capable of providing the service for the user equipment according to the service types of the cell services and the signal quality corresponding to the cells, and the service type of the service initiated by the user equipment. The method and device for cell selection, provided by the embodiments of the invention, are mainly applied to a process in which user equipment selects a cell when the user equipment initiates a service and performs handover.

Description

[0001] This application requires a divisional application of a Chinese patent application with the application number 201210058662.5 and the title of the invention "method and device for cell selection" submitted to the China Patent Office on March 7, 2012, the entire contents of which are incorporated in this application by reference . technical field [0002] The present invention relates to the technical field of wireless communication, in particular to a cell selection method and equipment. Background technique [0003] Wireless communication has entered a period of explosive growth of data services. Operators need to solve two problems at the same time: provide higher network capacity and reduce the transmission cost per bit. Currently, the use of Hetnet (heterogeneous network, heterogeneous network) is an important solution to the above problems. A Hetnet is a network composed of cells of different sizes and types. By deploying the cells in the Hetnet, it can provide...

AI Technical Summary

Problems solved by technology

At present, in Hetnet, when user equipment performs cell reselection or inter-cell handover, the user equipment or the network side only selects a new cell based on the signal quality, but due to the possible limitations of the service type of the new cell, it is impossible to provide the required information for the user equipment. Or the business being processed, this will cause the network side to control the user equipment to perform redirection or handover again, thereby increasing the signaling overhead load of the network and reducing the user experience
