Abstract

Information regarding available services from a RF communication system (101) is transmitted by the RF communication system on an RF communication resource(109). The information is received by at least one communication unit (108). The at least one communication unit (108) determines, from the information, the available services. The at least one communication unit (108) displays an indication of the available services on a display (206) for a user.

Claims

1. A method comprising the steps of

in a radio frequency (RF) communication system that provides a plurality of services, wherein each of the plurality of services has a status of either currently available, when the service is presently functional within the RF communication system, or currently unavailable, when the service is presently non-functional within the RF communication system, determining, by the RF communication system, when the status of one of the plurality of services changes from currently available to currently unavailable or when the status of one of the plurality of services changes from currently unavailable to currently available;

transmitting, by the RF communication system on an RF communication resource, information regarding currently available services from the RF communication system;

receiving the information by at least one communication unit;

determining, by the at least one communication unit, from the information the currently available services;

displaying, by the at least one communication unit, an indication of the currently available services.

2. The method of claim 1, wherein the determining step further comprises the step of decoding the information such that individual status indicators for the currently available services are translated into data ready for display.

3. The method of claim 1, wherein two or more RF communication systems transmit the information regarding the currently available services on one or more radio frequency communication resources.

4. A method comprising the steps of:

in a radio frequency (RF) communication system that provides a plurality of services, wherein each of the plurality of services has a status of either currently available, when the service is presently functional within the RF communication system, or currently unavailable, when the service is presently non-functional within the RF communication system, determining, by the RF communication system, when the status of one of the plurality of services changes from currently available to currently unavailable or when the status of one of the plurality of services changes from currently unavailable to currently available;

transmitting, by the RF communication system on an RF communication resource, information regarding currently available services from the communication system;

scanning the RF communication resource for the information by at least one communication unit;

determining, by the at least one communication unit, from the information the currently available services;

displaying, by the at least one communication unit, an indication of the currently available services;

determining, by the at least one communication unit, when to rescan the RF communication resource;

rescanning, by the at least one communication unit, the RF communication resource for new information;

determining, by the at least one communication unit, from the new information new currently available services;

displaying, by the at least one communication unit, an indication of the new currently available services.

5. The method of claim 4, wherein the currently available services are stored in the at least one communication unit.

6. The method of claim 4, wherein the new currently available services are stored in the at least one communication unit.

7. The method of claim 4, wherein the step of determining when to rescan further comprises the step of waiting a predetermined time between rescan steps.

8. The method of claim 7, wherein the predetermined time is a function of how many radio frequency communication systems are to be scanned.

9. The method of claim 7, wherein the predetermined time is a function of current activity level in the radio frequency communication system.

10. The method of claim 4, wherein the step of determining when to rescan further comprises the step of rescanning when a user of the at least one communication unit indicates a rescan is desired.

11. The method of claim 4, wherein the step of determining when to rescan further comprises the step of rescanning when the at least one communication unit is activated with a new service.

12. The method of claim 4, wherein two or more radio frequency communication systems transmit information regarding currently available services on one or more radio frequency communication resources.

13. A method for use by a communication unit for use in a radio frequency (RF) communication system that provides a plurality of associated services, wherein each of the plurality of associated services has a status of either currently available, when the service is presently functional within the RF communication system, or currently unavailable, when the service is presently non-functional within the RF communication system, the method comprising the steps of:

monitoring a radio frequency (RF) communication resource sourced by a RF communication system;

when activity is detected on the RF communication resource determining what services are associated with the RF communication system, based on the services currently used on the RF communication resource;

assuming that the associated services have a status of currently available services;

displaying an indication of services having a status of currently available services.

14. The method of claim 13, wherein two or more RF communication system are monitored on one or more RF communication resources sourced by the two or more RF communication systems.

15. The method of claim 14, further comprising the steps of:

remonitoring the one or more RF communication resources;

determining if new currently available services are on-line that were not on-line during a previous monitoring step;

displaying an indication of the new currently available services.
