Abstract

Claims (38)

1. A method for establishing communication to a mobile module, the method comprising:

initiating a plurality of call signals into the mobile module from a plurality of remote communication devices based on a timed sequence;

determining which of the plurality of call signals has established communication with the mobile module; and

terminating the call signals that have not established communication based on the determination.

2. The method of claim 1 further comprising:

determining whether a call signal in the timed sequence has established communication with the mobile module prior to initiating a next call signal; and

initiating the next call signal based on the determination.

3. The method of claim 1 wherein the step of initiating a plurality of call signals into the mobile module from a plurality of remote communication devices based on a timed sequence comprises:

initiating a first call signal at a first call time;

calculating a call time increment;

determining a next call time by adding the call time increment to the first call time; and

initiating a next call signal at the next call time.

4. The method of claim 1 wherein each call signal has a call signal position in the timed sequence.

5. The method of claim 4 wherein the call time increment is a function of the call signal position and a determined time constant.

6. The method of claim 1 further comprising:

monitoring the plurality of call signals into the mobile module for connection data;

writing the connection data for the mobile module to a call database; and

calculating a call offset for the mobile module based on the connection data for module in the call database.

7. The method of claim 1 further comprising:

determining a number of remote communication devices from which to initiate the plurality of call signals based on a service priority.

8. The method of claim 7 wherein the service priority is predetermined at a call center.

9. The method of claim 1 wherein the call signals are initiated sequentially.

10. The method of claim 1 wherein the plurality of remote communication devices is a bank of modems for generating the plurality of call signals.

11. A system for establishing communication to a mobile module comprising:

means for initiating a plurality of call signals into the mobile module from a plurality of remote communication devices based on a timed sequence;

means for determining which of the plurality of call signals has established communication with the mobile module; and

means for terminating the call signals that have not established communication based on the determination.

12. The system of claim 11 further comprising:

means for determining whether a call signal in the timed sequence has established communication with the mobile module prior to initiating a next call signal; and

means for initiating the next call signal based on the determination.

13. The system of claim 11 wherein each call signal has a call signal position in the timed sequence.

14. The system of claim 13 wherein the call time increment is a function of the call signal position and a determined time constant.

15. The system of claim 11 further comprising:

means for monitoring the plurality of call signals into the mobile module for connection data;

means for writing the connection data for the mobile module to a call database; and

means for calculating a call offset for the mobile module based on the connection data for the module in the call database.

16. The system of claim 11 further comprising:

means for determining a number of remote communication devices from which to initiate the plurality of call signals based on a service priority.
