Abstract
The described embodiments of the present invention include a method for controlling authorization of a multimedia service requested by a user device. In one embodiment, the method includes examining an identity of an access network associated with the user device and an identity of the service requested to determine whether the service is supported; authorizing resources in the access network required by the service if the service is supported; rejecting the service if the service is not supported and if a policy associated with the access network requires unsupported services to be rejected; and authorizing a default level of resources in the access network if the service is not supported and if the policy associated with the access network does not require unsupported services to be rejected.

13. A method for controlling authorization of a multimedia service requested by a user device comprising:
-
establishing a mobile IP connection with an access network;
acquiring an identity of the access network;
transmitting the identity of the access network to a SIP Proxy server of a core network;
launching a multimedia service;
providing an identify of the multimedia service to the SIP Proxy server;
wherein the SIP Proxy server examines an identity of an access network associated with the user device and an identity of the service requested to determine whether the service is supported, authorizes resources in the access network required by the service if the service is supported, rejects the service if the service is not supported and if a policy associated with the access network requires unsupported services to be rejected; and
authorizes a default level of resources in the access network if the service is not supported and if the policy associated with the access network does not require unsupported services to be rejected. - View Dependent Claims (14, 15, 16)

17. A system for providing access by a user to a multimedia service comprising:
-
a user device configured to establish a mobile IP connection with an access network, acquire an identity of the access network, transmit the identity of the access network to a session initialization proxy server, launch a multimedia service, and provide an identity of the multimedia service to the session initialization proxy server;
a home subscriber server having a database including access network identities and associated supported multimedia service identities;
the session initialization proxy server configured to query the home subscriber server for authorization of the multimedia service, authorize resources in the access network required by the service if the service is supported, reject the service if the service is not supported and if a policy associated with the access network requires unsupported services to be rejected; and
authorize a default level of resources in the access network if the service is not supported and if the policy associated with the access network does not require unsupported services to be rejected;
a policy function server configured to receive quality of service constraints from the session initialization proxy server and to supply corresponding quality of service parameters to an access gateway; and
the access gateway configured to allocate bearer level resources to support the multimedia service.
