Abstract

Systems and methods according to the present invention address this need and others by improving IMS service within the communications field. More particularly, systems and methods are described for controlling bandwidth.

Claims

1. A method for controlling bandwidth allocation in an Internet Multimedia Subsystem (IMS) communication system comprising:

evaluating IMS services currently being transmitted to a location;

determining, based upon said IMS services currently being transmitted to said location, a bandwidth allocation for IMS sessions associated with said IMS services currently being transmitted to said location; and

transmitting bandwidth allocation instructions, based upon said step of determining said bandwidth allocation for said IMS sessions.

2. The method of claim 1, wherein said step of determining said bandwidth allocation for IMS sessions associated with said IMS services currently being transmitted to said location further comprises:

selectively de-allocating bandwidth associated with at least one service which is being replicated to said location.

3. The method of claim 2, wherein the step of selectively de-allocating bandwidth associated with said at least one replicated IMS service to said location results in no redundant streams being transmitted to said location.

4. The method of claim 2, wherein said step of determining said bandwidth allocation for IMS sessions associated with said IMS services currently being transmitted to said location is further determined by information about IMS service usage associated with said location.

5. The method of claim 1, further comprising:

storing information about said IMS service usage associated with said location; and

receiving a message requesting an IMS service for said location.

6. The method of claim 5, wherein said information about IMS service usage associated with said location includes at least one of user policy information, user usage history, time of day and user patterns.

7. The method of claim 1, wherein said location includes a plurality of Internet Protocol Television (IPTV) Terminal Functions (ITFs).

8. The method of claim 1, wherein said IMS services include at least one of an IPTV channel and a streaming audio selection.

9. The method of claim 1, wherein said bandwidth allocation is for bandwidth between a digital subscriber line access multiplexer (DSLAM) and said location.

10. A communications node for controlling bandwidth allocation in an Internet Multimedia Subsystem (IMS) communication system comprising:

a memory for storing information about IMS services currently being transmitted to a location;

a processor for evaluating IMS services currently being transmitted to said location, wherein said processor further determines, based upon said IMS services currently being transmitted to said location, a bandwidth allocation for IMS sessions associated with said IMS services currently being transmitted to said location; and

a communications interface for transmitting bandwidth allocation instructions, based upon said step of determining said bandwidth allocation for each of said IMS services.

11. The communications node of claim 10, wherein said processor further determines bandwidth allocation for each IMS sessions associated with said IMS services currently being transmitted to said location by selectively de-allocating bandwidth associated with at least one IMS service which is being replicated to said location.

12. The communications node of claim 11, wherein selectively de-allocating bandwidth associated with at least one IMS service to said location results in no redundant streams being transmitted to said location.

13. The communications node of claim 11, wherein said processor further determines said bandwidth allocation for IMS sessions associated with said IMS services currently being transmitted to said location by using information about IMS service usage associated with said location.

14. The communications node of claim 10, wherein said memory further stores information about said IMS service usage associated with said location, and said communications interface further receives a message requesting a IMS service for said location.

15. The communications node of claim 14, wherein said information about IMS service usage associated with said location includes at least one of user policy information, user usage history, time of day and user patterns.

16. The communications node of claim 10, wherein said location includes a plurality of Internet Protocol Television (IPTV) Terminal Functions (ITFs).

17. The communications node of claim 10, wherein said IMS services include at least one of an IPTV channel and a streaming audio selection.

18. The communications node of claim 10, wherein said bandwidth allocation is for bandwidth between a digital subscriber line access multiplexer (DSLAM) and said location.

19. The communications node of claim 10, wherein said communications node is an Internet Protocol Television (IPTV) control server.
