Abstract:
1. A method: indicating in at least one capability information element within an outband signaling message the supported at least one type of information stream; adapting message flows of packet switched network signalling elements and circuit switched network signalling elements to enable an end-to-end multimedia capability negotiation; adapting the capability information between said packet switched network signalling elements and said circuit switched network signalling elements to enable an end-to-end multimedia capability negotiation; performing a capability negotiation by transmitting said capability information between a packet switched terminal and a circuit switched terminal or between said packet switched terminal and a multimedia control function, said circuit switched terminal device comprising at least one information processor, each information processor supporting at least one type of information stream; selecting at least one of said information processors based on the result of said capability negotiation; and establishing a multimedia connection using said selected at least one information processor between said packet switched terminal and said circuit switched terminal based on said selected type of information stream.
