Cell Locking Method for Mobile Terminal and Mobile Terminal Capable of Locking Cell
First Claim
1. A cell locking method for a mobile terminal, wherein said method comprises:
- step A. the mobile terminal searching a cell at a current location to acquire a system identification (SID), a network identification (NID), a base station identifier (BASE ID) and a pseudo-random number (PN) of said cell;
step B. judging whether said SID, said NID, said BASE ID and said PN are already stored in a database of said mobile terminal, if yes, then setting said mobile terminal to a normal status and transferring to step E, otherwise transferring to step C ;
step C. judging whether said SID, said NID, and said PN are already stored in the database of said mobile terminal and said database is not full, or said BASE ID and said PN are already stored in the database of said mobile terminal, if yes, then transferring to step D, otherwise setting said mobile terminal to a lock status and transferring to step E;
step D. writing said SID, said NID, said BASE ID and said PN into the database of said mobile terminal and setting said mobile terminal into a normal status and transferring to step E; and
step E. finishing lock procedure.

Abstract
A cell locking method for a mobile terminal and a mobile terminal capable of locking a cell are disclosed in the present invention. The method includes: the mobile terminal acquiring a system identification (SID), a network identification (NID), a base station identifier (BASE ID) and a pseudo-random number (PN) of a current cell; judging whether the SID, NID, BASE ID and PN are already stored in a database of the mobile terminal, if yes, then setting the mobile terminal to a normal status; judging whether the SID, the NID, and the PN are already stored in the database of the mobile terminal and the database is not full, or whether the BASE ID and PN are already stored in the database of the mobile terminal, if yes, then transferring to D; and D. writing the SID, NID, BASE ID and PN into the database of the mobile terminal.

8. A mobile terminal capable of locking a cell, wherein said mobile terminal comprises a current cell parameter acquisition unit, a data storage unit, a parameter comparison unit, a database writing-in unit and a status setting unit, wherein
the current cell parameter acquisition unit is used for acquiring a system identification (SID), a network identification (NID), a base station identifier (BASE ID) and a pseudo-random number (PN) of a current cell; -
the data storage unit is used for storing a database of the mobile terminal, wherein, the database includes the SID, NID, BASE ID and PN parameters; the parameter comparison unit is used for comparing the parameter acquired by the current cell parameter acquisition unit with the parameter stored in said data storage unit; the database writing-in unit is used for writing data into said database according to comparison result of said parameter comparison unit; the status setting unit is used for setting status of said mobile terminal according to the comparison result of said parameter comparison unit. - View Dependent Claims (9, 10, 11)
