Abstract
The present invention relates to a method and system for establishing a connection to a terminal device wherein a user capability information defining supported types of information streams is set in a compatibility information element within an outband signaling message and a capability negotiation is performed by transmitting said outband signaling message via an outband control channel. The code or user capability information may be set at the terminal device or at an intermediate network element based on a subscriber profile information obtained from a subscriber database. Thereby the user capability such as a multimedia session composition can be already negotiated or handled during the outband call setup phase and a corresponding inband negotiation can be avoided.
