Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] At present, mobile terminals of various standards support reporting network information to the user layer, and a very important item of the network information is a cell ID, that is, a cell identification number. The cell ID indicates the current cellular location of the mobile terminal, and the present invention uses the reported cell ID information to realize cell location locking of the mobile terminal.

[0025] As shown in Figure 1, when the mobile terminal is turned on at a certain location or the user performs some operation, the mobile terminal starts the cell locking process: the mobile terminal automatically searches for the signals of surrounding cells, and saves the searched cell ID and The cell IDs in the database are compared, if the cell ID has been stored in the database, then the current location of the mobile terminal is legal, the mobile termin...

Abstract

The method includes steps: (1) mobile terminal searches sector on current position, and determines whether ID number of sector is already saved on database of mobile terminal; if yes, then the current position of mobile terminal is legal, and operation is normal, then going to step (4), otherwise entering into step (2); (2) determining whether database is full; in not, then going to step (3); otherwise, the current position of mobile terminal is legal, and operation is not normal; if user requests unlocking sector of mobile terminal; then, after flow of unlocking sector, mobile terminal restarts up and returns back to step (1); otherwise, entering into step (4); (3) writing ID number of sector at current position into database, then the current position of mobile terminal is legal, and operation is normal, then going to step (4); (4) ending locking flow. The invention realizes requirement for restricting mobility of terminal, i.e. mobile terminal can work at specific sector.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cell locking method for a mobile terminal. Background technique [0002] With the rapid development of mobile communication technology, mobile terminals also present diversified development. Communication operators in various countries put forward various requirements for terminals according to their respective situations, and customization has become an important road for the development of mobile terminals. In order to ensure that terminals under their own network are not registered on other networks, operators in various countries customize the most for mobile terminals is the network lock requirement, which requires mobile terminals to only work under their own network. Although the network lock function can effectively limit the mobile range of mobile users under one's own network, it cannot limit mobile terminals to a very small range like fixed phones, so it cannot m...
