Abstract

A method of providing a radio communication unit (120) with information regarding radio communication services. The radio communication unit transmits a request regarding availability of one or more specific radio communication services. The radio communication unit then receives information regarding availability of the specified radio communication services.

Claims

1. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

determining, by the radio communication unit that at least one specified radio communication service is not presently available;

without requesting access to the at least one specified radio communication service, transmitting, from the radio communication unit, a status request regarding future availability of the at least one specified radio communication service for which the radio communication unit is currently authorized to use;

receiving at the radio communication unit information, including details regarding future availability of the at least one specified radio communication service, wherein the information includes geographic location regarding other availability.

2. The method of claim 1, wherein the step of transmitting is performed when information regarding availability of the specific radio communication service is not currently retained by the radio communication unit.

3. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

determining by the radio communication unit that at least one specified radio communication service is not presently available;

without requesting access to the at least one specified radio communication service, transmitting, from the radio communication unit, a status request regarding future availability of the at least one specified radio communication service for which the radio communication unit is currently authorized to use;

receiving at the radio communication unit information, including details regarding future availability of the at least one specified radio communication service, wherein the information includes temporal span regarding other availability.

4. The method of claim 3, wherein the step of transmitting is performed when information regarding availability of the specific radio communication service is not currently retained by the radio communication unit.

5. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

(a) determining that a need for a specific radio communication service exists;

(b) determining that the specific radio communication service is not presently available;

(c) determining whether any other information regarding availability of the specific radio communication service is currently retained by the radio communication unit;

(d) when the other information is not available, transmitting, from the radio communication unit, a request regarding other availability of the specified radio communication service;

(e) receiving at the radio communication unit information including details regarding the other availability of the specified radio communication service.

6. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

(a) determining that a need for a specific radio communication service exists;

(b) determining that the specific radio communication service is not presently available;

(c) determining whether any other information regarding availability of the specific radio communication service is currently retained by the radio communication unit;

(d) when the other information is currently retained by the radio communication unit, presenting the other information to a user of the radio communication unit;

(e) when the other information is not available, transmitting, from the radio communication unit, a request regarding other availability of the specified radio communication service;

(f) receiving at the radio communication unit information including details regarding the other availability of the specified radio communication service;

(g) providing the information to the user of the radio communication unit.

7. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

(a) determining that a need for a specific radio communication service exists;

(b) determining that the specific radio communication service is not presently available;

(c) determining whether any other information regarding availability of the specific radio communication service is currently retained by the radio communication unit;

(d) when the other information is currently retained by the radio communication unit, presenting the other information to a user of the radio communication unit;

(e) when either;

the other information is not available;

or

the user commands;

transmitting, from the radio communication unit, a request regarding other availability of the specified radio communication service;

(f) receiving at the radio communication unit information, including details regarding the other availability of the specified radio communication service;

(g) providing the information to the user of the radio communication unit.

8. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

determining, by the radio communication unit, that at least one specified radio communication service is not presently available;

without requesting access to the at least one specified radio communication service, transmitting, from the radio communication unit, a status request regarding future availability of the at least one specified radio communication service for which the radio communication unit is currently authorized to use;

receiving at the radio communication unit information, including details regarding future availability of the at least one specified radio communication service.

9. The method of claim 8, wherein the information includes a geographic location where the at least one specified radio communication service is capable of being accessed by the radio communication unit.

10. The method of claim 8, wherein the information includes time information indicating when the at least one specified radio communication service is capable of being accessed by the radio communication unit.

11. The method of claim 8, wherein the step of transmitting is performed when information regarding availability of the specific radio communication service is not currently retained by the radio communication unit.

12. A method of providing a radio communication unit with information regarding radio communication services, comprising the steps of:

determining, by the radio communication unit, that at least one specified radio communication service is not presently available;

without requesting access to the at least one specified radio communication service, transmitting, from the radio communication unit, a status request regarding future availability of the at least one specified radio communication service for which the radio communication unit is currently authorized to use but is currently unavailable for use by the radio communication unit;

receiving at the radio communication unit information, including details regarding future availability of the at least one specified radio communication service.

13. The method of claim 12, wherein the information includes a geographic location where the at least one specified radio communication service is capable of being accessed by the radio communication unit.

14. The method of claim 12, wherein the information includes time information indicating when the at least one specified radio communication service is capable of being accessed by the radio communication unit.

15. The method of claim 12, wherein the step of transmitting is performed when information regarding availability of the specific radio communication service is not currently retained by the radio communication unit.
