Problems solved by technology

Then, because there are many frequency points in the frequency band, the first n frequency points are generally used to try to synchronize and reside in the cell after frequency scanning. It does not include the frequency point of the cell that should be resident, so that the terminal equipment cannot always reside in the normal cell and cannot perform business

Embodiment Construction

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0056] Embodiment of the method for realizing fast cell selection in the wireless communication system

[0057] figure 1 The general process of cell camping in the method for realizing fast cell selection in the wireless communication system of the present invention is shown. For the overall process of camping in fast cell selection, including: figure 1 the four steps shown.

[0058] Step S100: When the mobile device is powered on, the upper-layer application module will trigger a mobile management layer MM (Mobile Management) registration request, carrying the PLMN selection mode and PLMN information. Next, step S101 is performed, and the MM requests an RR (Radio Resources, Radio Resources) to select a network and reside. PLMN selection mode is divided into automatic mode and manual mode. PLMN is composed of MCC (Mobile Country Code) and MNC (Mobi...

Abstract

The invention discloses a method and a system for implementing quick cell selection in a wireless communication system. A mobile device is allowed to quickly select effective cells, time for cell selection is reduced, and work performance is stable and reliable. According to the technical scheme, when the mobile device is allowed to execute full-frequency-band scanning (after the mobile device is turned on, the mobile device not carrying a storage list or cells in the storage list are not suitable for lingering and enter a coverage area from a blind area, or useless neighbor cells are reselected) to select cells, cells, which are lingered to cells in a PLMN (public land mobile network) frequency point list which is stored by the mobile device matched with a pointed PLMN are given priority to trial, an electric level value of a priority trail frequency point is higher than threshold I, and cells with PLMNs ensured to be inconsistent are no longer tried.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for realizing fast cell selection by a mobile device in a wireless communication system. Background technique [0002] GSM (Global System for Mobile communications, Global System for Mobile Communications) is the most widely used digital mobile communication system in the world. [0003] When the mobile device is turned on or enters the coverage area from a blind area, it will try to find all the frequency points allowed by the public land mobile network PLMN (Public Lands Mobile Network), so the mobile device will choose a suitable cell to reside in. This process is called Cell selection. [0004] my country's terrestrial cellular digital mobile communication network GSM communication system uses 900MHz and 1800MHz frequency bands. The GSM900MHz frequency band is: 890-915MHz (transmitting from the mobile station, receiving from the base station...
