Abstract

A method and apparatus for reducing messaging traffic, including air and network messaging, in a wireless communication system. The invention informs a mobile station of its subscription status, either active or inactive, within the communication system. If the mobile station subscription status is inactive, the mobile station is prevented from registering with the communication system. All other functions of the inactive mobile remain enabled, such as the ability to make emergency calls, to change the subscription status to active status, or to allow for base station maintenance control.

Claims

1. A method for reducing messaging traffic, including air and network messaging, in a wireless communication system, said system comprising a mobile switching center, at least one mobile station, and at least one base station, said method comprising the steps of:

providing at least one mobile station with a mobile station subscription status;

storing said mobile station subscription status in a memory device;

preventing said mobile station from registering with said communication system if said mobile station subscription status indicates that said mobile station is inactive.

2. The method of claim 1 further comprising the step of:

allowing said at least one mobile station to otherwise communicate with said mobile switching center, even when said mobile station subscription status indicates that said mobile station is inactive.

3. The method of claim 1 further comprising the steps of:

transmitting an acknowledgment message from said mobile station to said mobile switching center upon storing said mobile station subscription status in said memory device; and

re-transmitting said mobile station subscription status by said mobile switching center if said acknowledgment message is not received by said mobile station switching center within a predetermined amount of time.

4. The method of claim 3 wherein the step of re-transmitting said mobile station subscription status is repeated for a predetermined number of times.

5. The method of claim 2 wherein the step of allowing said at least one mobile station to otherwise communicate with said mobile switching center includes the ability to make emergency calls.

6. The method of claim 2 wherein the step of allowing said at least one mobile station to otherwise communicate with said mobile switching center includes the ability to provide Over-The-Air programming to said at least one mobile station.

7. An apparatus for reducing messaging traffic, including air and network messaging, in a wireless communication system, said system comprising a mobile switching center, at least one mobile station, and at least one base station, said apparatus comprising:

a memory device for storing a mobile station subscription status;

a transceiver for communicating to at least one base station;

a first processor, connected to said memory device and said transceiver, for receiving said mobile station subscription status and for storing said mobile station subscription status in said memory device;

wherein said mobile station is prevented from registering with said communication system if said mobile station subscription status is inactive.

8. The apparatus of claim 7 wherein said first processor sends an acknowledgment message to said mobile switching center if said mobile station subscription status has been altered.

9. The apparatus of claim 8 further comprising a timer connected to a second processor, for providing the time that a mobile station subscription status was transmitted, wherein said second processor re-transmits said mobile station subscription status if said acknowledgment message is not received within a predetermined amount of time from when said mobile station subscription status was last transmitted.

10. The apparatus of claim 7 wherein said memory device is a nonvolatile memory.

11. The apparatus of claim 7 further comprising an I/O device for altering said mobile station subscription status in said memory device.

12. The apparatus of claim 11 wherein said I/O device comprises a keypad and display.
