Abstract

A system (100) and method (200) is provided to customize services (150). The method can include conveying (204) access network information from a user device to a core network using a SIP message, and adapting (206) a service provided by the core network according to the access network information contained in the SIP message. The method can include creating a header field to convey the access network information. A roaming status indictor can be included in a SIP SUBSCRIBE, a SIP INVITE, a SIP MESSAGE or a SIP REGISTER for adapting the delivery of presence state information concerning a resource.

Claims

1. A method to customize services, comprising the steps of:

conveying access network information from a user device to an entity within a core network through a SIP message; and

adapting a service provided or supported by said core network according to said access network information contained in said SIP message.

2. The method of claim 1, wherein said conveying access network information further comprises including a header field in said SIP message to convey said access network information.

3. The method of claim 2, further comprising including said header in a SIP message, wherein said access network information includes one or more of a roaming status, a call quality statistic information, a quality of service information, an inter-technology handover indication, an RF loss history indicator, a signal strength indicator for each RF technology, a mobility or handoff rate indicator, battery life, a background audible noise indication, and a coverage transition indication.

4. The method of claim 2, further comprising including said header in one of a SIP SUBSCRIBE, SIP INVITE, SIP REFER, or SIP UPDATE message for performing at least one of requesting state information concerning a resource or communicating with a service entity in the core network,

wherein said access network information includes at least one of a roaming status, a call quality statistic information, a quality of service information, an inter-technology handover indication, and a coverage transition indication.

5. The method of claim 1, wherein said adapting includes one of filtering and throttling media sent from said entity within the core network to said user device in accordance with the access network information.

6. The method of claim 1, wherein said access network information is a link level quality information based on one of measured data and estimated conditions for expected duration of session.

7. The method of claim 1, further comprising adapting said service to optimize a service behavior based on said access network information.

8. The method of claim 1, wherein said adapting comprises:

identifying a roaming condition and adapting based on a profile associated with said service and said condition,

wherein said profile includes a first set of features and behaviors associated with a home network, and a second set of features and behaviors associated with said roaming condition,

wherein said features and behaviors describe which services are required by a user or allowed by an operator during roaming and how the services operate.

9. The method of claim 3, further comprising the steps of:

sending a roaming status in a SIP REGISTER message; and

increasing a re-registration timer in response to said roaming status.

10. The method of claim 1, further comprising one of disabling and enabling an optional feature including at least one of group advertisement, personal alert, forwarding of session invitations to a media recording and storage device, condition-based incoming and outgoing session barring, incoming media barring, and filtering of media content from session invitation.

11. The method of claim 1, further comprising one of accepting and rejecting a subscription to participant information.

12. A method for managing information traffic while roaming, comprising the steps of:

identifying a profile associated with a roaming condition based on a trigger;

adjusting a delivery of media according to said profile; and

upon exiting said roaming condition, restoring said delivery of media according to a profile associated with a home network condition.

13. The method of claim 12, wherein said trigger is an indication in one of a SIP REGISTER, SIP INVITE, SIP REFER, SIP UPDATE, SIP NOTIFY, SIP MESSAGE and a SIP SUBSCRIBE.

14. The method of claim 12, further comprising one of filtering, delaying or aggregating said media during said roaming when sending said media.

15. The method of claim 12, further comprising updating a charging associated with said delivery of media.

16. A system for customizing services comprising a network element for receiving access network information from a user device through a header field in a SIP message and adapting a service supported by the network in accordance with the access network information.

17. The system of claim 16 wherein the header field defines one of a roaming status, a call quality statistic information, a quality of service information, an inter-technology handover, a coverage transition indication, and a link quality indication.

18. The system of claim 16, wherein said SIP message is a SIP REGISTER message for registering for IMS services.

19. The system of claim 16, wherein said SIP message is one of a SIP SUBSCRIBE message, SIP INVITE message, SIP REFER message, SIP UPDATE message, SIP Message message and SIP NOTIFY message.

20. A method for managing presence traffic, comprising the steps of:

subscribing to a resource that provides presence information through a presence service;

receiving notifications from said service to update said presence information;

providing access network information associated with a delivery of said presence information from said service; and

adapting said service according to said access network information for managing presence information traffic.

21. The method of claim 20, wherein providing access network information comprises including a header field in one of a SIP SUBSCRIBE, SIP INVITE, SIP REFER, SIP UPDATE, SIP NOTIFY, SIP MESSAGE and a SIP REGISTER messages.
