Method for realizing fast cell reselection by mobile equipment in wireless communication system

Abstract

The invention relates to a method for mobile equipment in a wireless communication system to realize rapid cell reselection. The method comprises the steps as follows: the mobile equipment selects an appropriate cell as a present service cell, receives and decodes the system information of the service cell and a broadcast control channel data block, obtains a broadcast control channel assignment list of an adjacent cell, maintains the relevant information of the service cell, generates an adjacent cell frequency point list according to the broadcast control channel assignment list of the adjacent cell, maintains the adjacent cell frequency point list, and combines the relevant information of a reselected target cell and the present service cell to perform the cell reselection judgment examining and cell switching operations. The method for the mobile equipment in the wireless communication system to realize rapid cell reselection is adopted, thereby effectively reducing the generation of cell reselection, remarkably improving the cell reselection stability and the cell reselection process speed of the mobile equipment, and improving the service quality and the running efficiency of the wireless communication; and the performance is stable, the applicable range is wide, and the solid foundation is laid for the completeness and the development of the mobile communication.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to the technical field of cell reselection of a mobile device in a wireless communication system, in particular to a method for fast cell reselection of a mobile device in a wireless communication system. Background technique [0002] GSM (Global System for Mobile communications, that is, the global system for mobile communications) is a digital mobile communication system that is currently the most widely used in the world. [0003] In the GSM communication system, cell selection and cell reselection need to use the content of the BCCH (Broadcast Control Channel, broadcast control channel) assignment table of neighboring cells to judge, for example, whether it can pass the neighboring cell BCCH after power on. The assignment table performs fast cell selection, whether the target neighbor cell is suitable for reselection, etc. It can be said that the neighbor cell BCCH ...

Problems solved by technology

[0024] It is conceivable that in the current existing technology, due to the influence of uncontrollable factors such as climate, terrain, and man-made wireless environment, the target cell must be unstable when cell reselection occurs, resulting in frequent cell reselection ;Usually read all the system information after the cell reselection occurs, which will inevitably lead to the prolongation of the cell reselection process; and the cell reselection is performed after the downlink signaling failure occurs, etc.

The above situations will cause unstable operation of mobile devices, frequent network signaling interaction, unreasonable allocation of network signaling resources and other unfavorable situations.
