Problems solved by technology

[0004] However, in the actual network environment, since the bandwidth covered by some frequency bands is relatively large, and multiple operators have deployed multiple networks in such frequency bands, mobile terminals need to operate in such a complex network deployment environment. When searching for full-band cells, many unsuitable cells will be found due to interference, and the terminal needs to spend a lot of time performing synchronization and read broadcast operations on these unsuitable cells to determine that these cells are not suitable for camping, which increases the The delay in cell search reduces the efficiency of finding a suitable cell and seriously affects user experience

Abstract

The embodiment of the invention discloses an updating method and an updating device of a sub-band search association table, a cell search method and a cell search device. The updating method of the sub-band search association table comprises the following steps: acquiring a central frequency point of a cell searched by a mobile terminal, bandwidth of the cell and public land mobile network PLMN information of the cell; calculating sub-band of the cell according to the central frequency point and the bandwidth; and adding information of a corresponding relation of the sub-band of the cell and the PLMN information of the cell into the sub-band search association table. The methods and the devices provided by the invention solve the technical problem that the cell search method in the prior art increases delay of cell search, reduces efficiency of searching an appropriate cell and seriously influences experience of users, optimize the existing cell search technology, and meet the increasing personalized and convenient cell search demands of people.

Description

technical field [0001] The embodiments of the present invention relate to mobile communication technologies, and in particular to a method and device for updating a sub-frequency band search association table, and a cell search method and device. Background technique [0002] With the rapid development of mobile communications, the user base of smart terminals is also growing exponentially. In order to meet the increasingly demanding needs of users, the protocol stack of the terminal chip needs to strictly follow the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project ) protocol based on appropriate process optimization to improve user satisfaction. Among them, a very important item is the optimization process of the cell search. The shorter the cell search delay, the faster the user can access the network to initiate services and receive paging, so that the user can better experience the seamless mobile connection. At the same time, if the cell sea...
