Wireless vehicle burglar-alarm system
First Claim
1. A wireless vehicle burglar-alarm system comprising:
- an on-board main unit installed in a car and electrically connected to at least one sensor and at least one alarm in said car, each said sensor being adapted to detect an abnormal status of a predetermined location in said car and to produce an abnormality signal upon detection of an abnormal status of said predetermined location, said on-board main unit being adapted to receive said abnormality signal from each said sensor and to control said at least one alarm to produce an alarm signal upon receive of said abnormality signal; and
a wireless communication apparatus installed in said car and electrically connected to said on-board main unit and adapted to receive the broadcast of at least one base station of one wireless communication system and to store the Cell Global Identity of each base station of said wireless communication system;
wherein when said on-board main unit is in an alert mode and when one stored Cell Global Identity is disappeared from said wireless communication apparatus and said wireless communication apparatus has the Cell Global Identity of one new base station stored therein, said wireless communication apparatus sends a relocation signal to said on-board main unit, causing said on-board main unit to start said at least one alarm.

Abstract
A wireless vehicle burglar-alarm system formed of an on-board main unit and a wireless communication is disclosed. The on-board main unit obtains the CGI (Cell Global Identity) of a wireless communication base station from its broadcast and stores the CGI in a memory, and sends a re-location signal to the on-board main unit when the storage CGI is changed during an alert mode of the on-board main unit, causing the on-board main unit to start the at least one alarm. The on-board main unit sends an alarm signal to an alarm and drives the wireless communication apparatus to send an alarm message to the car owner wirelessly upon detection of an abnormal condition of the car through a sensor.
