Abstract

A bulletin board coordinates the service authorization for other communication systems. Service authorizations are periodically updated, with authorized communication units returning to the bulletin board at pre-scheduled times to receive the updates that extend service authorization for authorized communication services. The bulletin board transmits authorization information on known communication resources at predetermined times known only by authorized communication units.

Claims

1. A method of maintaining access authorization of communication services for a radio, comprising the steps of:

using communication resources that correspond to the communication services for which the radio has previously gained a service authorization;

accessing a bulletin board communication resource to extend the service authorization for at least one of the communication services;

receiving, from the bulletin board communication resource, an authorization code corresponding to the at least one of the communication services; and

returning to the communication resources for at least the communication service for which service extension was authorized.

2. The method of claim 1, further including the step of, when shutting off the radio to temporarily discontinue the communication services, determining a time to later automatically activate the radio to facilitate accessing the bulletin board communication resource.

3. The method of claim 1, wherein the step of accessing the bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of receiving an updated authorization code.

4. The method of claim 3, wherein the step of returning to the communication resources for at least the communication service for which service extension was authorized further includes the step of using the updated authorization code to gain usage of at least one of the communication resources.

5. The method of claim 1, wherein the step of accessing the bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of receiving, on the bulletin board communication resource, updated operating instructions to allow the radio to properly function with a corresponding communication service.

6. The method of claim 5, wherein the updated operating instructions include functional software code.

7. The method of claim 5, wherein the updated operating instructions include a time at which the updated operating instructions are to be used when using the corresponding communication service.

8. The method of claim 1, wherein the step of accessing a bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of accessing the bulletin board communication resource when denied service on one of the communication services.

9. The method of claim 8, wherein the step of accessing the bulletin board communication resource when denied service on one of the communication services further includes the step of automatically so accessing the bulletin board communication resource.

10. The method of claim 1, wherein the step of accessing a bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of receiving, on the bulletin board communication resource, information regarding arrears in payments for at least one of the communication services.

11. The method of claim 10, wherein the step of accessing a bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of satisfying the arrears in payments using the bulletin board communication resource.

12. The method of claim 1, further including the step of automatically accessing the bulletin board communication resource to extend the service authorization for at least one of the communication services.

13. The method of claim 12, wherein the step of automatically accessing the bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of automatically accessing the bulletin board communication resource at a predetermined time to extend the service authorization for at least one of the communication services.

14. The method of claim 13, further including the step of receiving from the bulletin board communication resource the predetermined time.

15. The method of claim 12, wherein the step of automatically accessing the bulletin board communication resource to extend the service authorization for at least one of the communication services further includes the step of automatically activating the radio to support communications with the bulletin board communication resource.

16. A method of controlling access authorization to communication services for a radio, comprising the steps of:

using communication resources that correspond to the communication services for which the radio has previously gained a service authorization;

accessing a bulletin board communication resource to facilitate control of the service authorization for at least one of the communication services;

when service is to be continued, receiving, from the bulletin board communication resource, information that facilitates continuation of service to at least one communication service, wherein the information comprises at least an authorization code;

when service is to be interrupted, receiving, from the bulletin board communication resource, information that provides notification of interruption of service to at least one communication service; and

returning to the communication resources for at least the communication service for which service extension was authorized.

17. The method of claim 16, wherein the step of receiving, from the bulletin board communication resource, information that provides notification of interruption of service to at least one communication service further includes the step of receiving, from the bulletin board communication resource, information that facilitates interruption of service to at least one communication service.

18. A method of maintaining access authorization to at least one radio communication service that is supported by a first radio communication system for a two-way radio, comprising the steps of:

using at least one radio communication resource that corresponds to the at least one radio communication service for which the two-way radio has previously gained a service authorization;

accessing a bulletin board communication resource, which bulletin board communication resource is supported by a second radio communication system, which second radio communication system is separate from the first radio communication system, to continue the service authorization of the two-way radio for the at least one radio communication service;

receiving, from the bulletin board communication resource, an authorization code corresponding to the at least one radio communication service; and

returning to at least one radio communication resource for which service continuation was authorized.
