ABSTRACT:
A profile for bearer data as found in IuUP and NbUP so that it can be signaled over SDP. The present invention provides AAL2 profiles that can be used to describe AAL2 bearer connections in a radio access network between a radio network controller (RNC) and a media gateway, or between two media gateways in a core network. In an embodiment, the call agent is a wireless call agent, such as a mobile switching center (MSC). The profiles provided by the present invention are used by the call agent to set up AAL2 bearer connections on the media gateway.
