Abstract

Systems and methods according to these exemplary embodiments provide for methods and systems for negotiating resources in a communication system. One exemplary method includes transmitting, by a service manager, a request for a service, wherein the service request either explicitly provides, or implicitly refers to, a list of a plurality of service options for providing the service. Additionally, a resource manage can receive the transmission request from a service manager and process the request based upon either the explicitly transmitted list of service options or the reference to a list of service options.

transmitting a reply to said request for service indicating which of said plurality of service options has been selected by said resource manager for providing said service.

7. The method of claim 6, wherein said list of said plurality of service options includes ranking information associated with an end user'"'"'s preferences for receiving said service.

8. The method of claim 6, wherein said list of said plurality of service options is ordered based upon an end user'"'"'s preferences for receiving said service.

9. The method of claim 4, further comprising:

receiving, at a resource manager, said request,

retrieving, from a memory device associated with said resource manager, said list of said plurality of service options,

evaluating said list to determine a highest ranked one of said plurality of service options which can be used to provide said service, and

transmitting a reply to said request for service indicating which of said plurality of service options has been selected by said resource manager for providing said service.

10. The method of claim 1, wherein said service manager is a server which provides the functions of publishing, discovering, subscribing, invoking and delivering Quality of Service (QoS) enabled services.

11. The method of claim 1, wherein said service is a movie to be provided from an application function to an end user.

12. A method for negotiating resources in a communication system comprising:

receiving, by a resource manager, a request for a service,

wherein said service request either explicitly provides, or implicitly refers to, a list of a plurality of service options for providing said service.

13. The method of claim 12, wherein said service request explicitly provides said list of said plurality of service options and further wherein:

said request is a message including said list of said plurality of service options, each entry in said list including a plurality of parameters.

14. The method of claim 12, wherein said plurality of parameters include at least one of:

a bandwidth to be used to provide said service, a codec to be used to provide said service and a format to be used to provide said service.

15. The method of claim 12, wherein said service request implicitly refers to said list of a plurality of service options and further wherein:

said request is a message including an address of an end-user device and an identifier associated with said service.

16. The method of claim 15, wherein said request does not include parameters associated with at least one of:

a requested bandwidth, a requested codec and a requested format.

17. The method of claim 13, further comprising:

evaluating said list to determine a highest ranked one of said plurality of service options which can be used to provide said service, and

transmitting a reply to said request for service indicating which of said plurality of service options has been selected by said resource manager for providing said service.

18. The method of claim 17, wherein said list of said plurality of service options includes ranking information associated with an end user'"'"'s preferences for receiving said service.

19. The method of claim 17, wherein said list of said plurality of service options is ordered based upon an end user'"'"'s preferences for receiving said service.

20. The method of claim 15, further comprising:

retrieving, from a memory device associated with said resource manager, said list of said plurality of service options,

evaluating said list to determine a highest ranked one of said plurality of service options which can be used to provide said service, and

transmitting a reply to said request for service indicating which of said plurality of service options has been selected by said resource manager for providing said service.

21. The method of claim 12, wherein said resource manager is a server which provides the functions of:

reserving, allocating and monitoring network resources within a domain based on reservation requests received from a service manager.

22. The method of claim 12, wherein said service is a movie to be provided from an application function to an end user.

23. A communications node for negotiating resources in a communication system comprising:

a processor for transmitting a request for a service,

wherein said service request either explicitly provides, or implicitly refers to, a list of a plurality of service options for providing said service.

24. The communications node of claim 23, wherein said service request explicitly provides said list of said plurality of service options and further wherein:

said request is a message including said list of said plurality of service options, each entry in said list including a plurality of parameters.

25. The communications node of claim 23, wherein said plurality of parameters include at least one of:

a bandwidth to be used to provide said service, a codec to be used to provide said service and a format to be used to provide said service.
