Abstract

A radio communication system (100, 200) employs a method of providing communication services to a communication unit (104, 105) having a plurality of service requirements. The radio communication system (100, 200) further includes a plurality of service providers (101-103) for which the communication unit catalogues (506, 512) service attributes as part of the inventive method. Further, for each of the service requirements, the communication unit (104, 105) selects (514) one of the plurality of service providers (101-103) to facilitate that service requirement.

Claims

1. In a communication system comprising separate service providers, a method of enabling a communication unit to select separate service providers to individually satisfy its communication service needs,

the method comprising the communication unit performed steps of:

cataloguing service attributes for each of the plurality of service providers;

identifying a request for a communication;

and,

for at least two service needs of the communication unit, simultaneously selecting for affiliation, on the basis of said catalogued service attributes, at least two corresponding separate ones of said service providers capable of servicing said at least two service needs;

wherein each service provider maintains an affiliation list identifying each communication unit affiliated therewith and the associated service need, and whereby the step of identifying the communication request is in response to a service provider identifying the communication unit as being affiliated and forwarding the request thereto.

2. The method of claim 1, wherein the step of cataloguing includes the step of querying a centralized service directory.

3. The method of claim 1, wherein the step of cataloguing includes the step of querying at least one of the plurality of service providers.

4. The method of claim 1, wherein the step of simultaneously selecting comprises the step of identifying a minimum number of service providers that collectively facilitate all of the service needs of the communication unit.

5. The method of claim 1, wherein the step of simultaneously selecting comprises the step of identifying a set of service providers that collectively facilitate all of the service needs of the communication unit.

6. The method of claim 1, wherein the step of cataloguing comprises the steps of:

for each service need, identifying at least one service provider capable of supporting that service need to produce at least one identified service provider; and

recording a signal quality metric for each of the at least one identified service provider.

7. The method of claim 6, wherein the step of simultaneously selecting comprises the step of selecting, for each service need, a service provider having a favorable signal quality metric associated therewith.

8. The method of claim 1, wherein the step of cataloguing comprises the steps of:

for each service need, identifying at least one service provider capable of supporting that service need; and

recording a resource usage metric for each of the at least one identified service provider.

9. The method of claim 8, wherein the step of simultaneously selecting comprises the step of identifying, for each service need, a service provider having a favorable resource usage metric associated therewith.

10. The method of claim 1, wherein the step of cataloguing comprises the steps of:

for each service need, identifying at least one service provider capable of supporting that service need; and

recording a resource availability metric for each of the at least one identified service provider.

11. The method of claim 10, wherein the step of simultaneously affiliating comprises the step of identifying, for each service need, a service provider having a favorable resource availability metric associated therewith.

12. The method of claim 1, further comprising the step of affiliating to the at least two corresponding separate ones of said service providers.

13. The method of claim 1, further comprising the step of:

affiliating to the at least two corresponding separate ones of said service providers, wherein the step of identifying the request for the communication, includes monitoring each affiliated service provider to identify the communication request.

14. The method of claim 1, further comprising the step of affiliating to the at least two corresponding separate ones of said service providers, the request being forwarded to the communication unit from said at least two affiliated service providers.

15. The method of claim 1, wherein the step of identifying the communication request is in response to a service provider forwarding the request to a centralized notification board and the communication unit monitoring the centralized notification board to identify said request.

16. In a communication system comprising separate service providers, a method of enabling a communication unit to select separate service providers to individually satisfy its communication service needs,

the method comprising the communication unit performed steps of:

querying a centralized service directory to determine service attributes for each of the plurality of service providers;

identifying a request for a communication;

and

for each service need of the communication unit, affiliating with a corresponding separate one of said service providers capable of servicing that service need;

wherein at least a first service provider comprises an affiliation list including affiliation information of the other service providers, and whereby in response to the request for a communication with the communication unit and the affiliation information, said at least first service provider forwards the request to the service provider with which said communication unit is presently affiliated.

17. The method of claim 16, wherein the step of affiliating comprises the step of identifying a minimum number of service providers that collectively facilitate all of the service needs of the communication unit.

18. The method of claim 16, wherein the step of affiliating comprises the step of identifying a set of service providers that collectively facilitate all of the service needs of the communication unit.

19. The method of claim 16, wherein the step of affiliating comprises the step of identifying, for each service need, a resource usage metric associated therewith.

20. The method of claim 19, wherein the step of affiliating comprises the step of identifying, for each service need, a service provider having a favorable resource usage metric associated therewith.

21. The method of claim 16, further comprising the step of identifying by the communication unit a communication request thereto, wherein the step of identifying the communication request is in response to a service provider forwarding the request to a centralized notification board and the communication unit monitoring the centralized notification board to identify said request.

22. In a communication system comprising separate service providers, a method of enabling a communication unit to select separate service providers to individually satisfy its communication service needs,

the method comprising the communication unit performed steps of:

querying each of the plurality of service providers to determine service attributes associated therewith;

identifying a request for a communication;

and

for each service need of the communication unit, affiliating with a corresponding separate one of said service providers capable of servicing that service need;

wherein at least a first service provider comprises an affiliation list including affiliation information of the other service providers, and whereby in response to the request for a communication with the communication unit and the affiliation information, said at least first service provider forwards the request to the service provider with which said communication unit is presently affiliated.

23. The method of claim 22, wherein the step of affiliating comprises the step of identifying a minimum number of service providers that collectively provide all of the service needs of the communication unit.

24. The method of claim 22, wherein the step of affiliating comprises the step of identifying a set of service providers that collectively provide all of the service needs of the communication unit.

25. The method of claim 22, further comprising the step of determining, for each affiliated service provider, a signal quality metric associated therewith.

26. The method of claim 25, wherein the step of affiliating comprises the step of identifying, for each service need, a service provider having a favorable signal quality metric associated therewith.
