Base station searching method and terminal

Abstract

The invention provides a base station searching method and a terminal. The terminal removes a base station which is not met with preset base station selection conditions according to the acquired information of the base station, and other base stations are continuously scanned until the terminal is accessed to the base station meeting the base station selection conditions. The method provided by the invention comprises the steps of removing special sub base stations which can not be accessed by the terminal step by step according to the sequence of acquisition time of information of a base station, namely if the early acquired information of the base station is not met with the base station selection conditions, the base station is directly determined to be an improper base station and is removed, a process for scanning other base stations is initiated again, and the lately acquired information of the base station is not judged any more. In the base station searching method provided by the invention, the terminal requires no searching according to the complete base station information of each base station, and the base stations which can not be accessed by the terminal are removed in advance, thus realizing rapid and accurate access of the base station, greatly improving scanning, accessing and switching performances of a wireless communication system and reducing communication and terminal costs.

Description

technical field [0001] The invention relates to a terminal access technology in a wireless communication system, in particular to a base station search method and a terminal. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services to a terminal, and the base station and the terminal communicate wirelessly through electromagnetic waves. Through the base station, the wireless communication system can provide wireless coverage for terminals in a certain geographical range, and this geographical range is called a cell. [0003] Generally, in order to provide wireless communication for users in a wide range, a wireless communication system needs to deploy a base station with a large coverage. Such a base station is generally called a macro base station (Macro BS), and a cell covered by it is generally called a macro cell (Macro Cell). At the same time, wireless communication systems need to provide users with hi...

Problems solved by technology

In this way, in the case of dense dedicated femto base stations, the existing scanning method for searching base stations by terminals may need to be repeated many times, which reduces the scanning efficiency and increases the overall switching overhead, thus increasing the overall network access overhead
