Method for mobile terminal in third-generation mobile communication system to receive and maintain system information

Abstract

The invention relates to a method for a mobile terminal in a third-generation mobile communication system to receive and maintain system information, comprising the following steps: setting the mobile terminal in an idle or connected mode; measuring and judging whether a reelection rule is satisfied or not by an adjacent cell; performing cell reelection and synchronous processing of a target cell when the reelection rule is satisfied; judging whether the system information of the target cell is received and stored or not; obtaining and analyzing the information of a main information block of the target cell or obtaining the information of the main information block of the target cell and all system information according to results; and judging whether the target cell allows to reside or not, if so, residing to the target cell and performing system information updating and replacing operation. The method for the mobile terminal in the third-generation mobile communication system to receive and maintain system information effectively lowers the power consumption of the mobile terminal, improves the running efficiency of the system, has simple and rapid arithmetic, convenient realization, stable and reliable working performance and wide range of application, and lays a solid foundation for the perfection and the optimization of the third-generation mobile communication system.

Description

technical field [0001] The invention relates to the field of third-generation mobile communication, in particular to the field of receiving system information of a third-generation mobile communication terminal, and specifically refers to a method for receiving and maintaining system information by a mobile terminal in a third-generation mobile communication system. Background technique [0002] In the field of WCDMA and TD-SCDMA technology, the development of communication technology and the improvement of user demand have made it possible to transmit multiple services concurrently. For example, a mobile terminal user may need to transmit data, language and other service streams at the same time. However, the increase in service requirements will lead to an increase in the power consumption of the mobile terminal. [0003] In the prior art, when a mobile terminal reselects from one cell to another, the mobile terminal needs to re-receive all the system messages of the new c...

However, the improvement of business requirements will lead to an increase in the power consumption of mobile terminals.

[0003] In the prior art, when a mobile terminal reselects from one cell to another, the mobile terminal needs to re-receive all the system messages of the new cell and judge whether the new cell is allowed to camp, because receiving all the system messages increases the number of reselections. The process time will also increase the power consumption of the mobile terminal, which will greatly affect the standby time of the mobile terminal, increase the load of the mobile communication network, reduce the efficiency of mobile communication, and increase the cost of mobile communication
