[0031] The first embodiment of the present invention will now work with image 3 Introduce together. exist image 3 The method disclosed in includes a voice call setup from A to B, followed by A-initiated video setup. This method will show a registration control that clarifies to the originating A client what session model the terminating B client uses, ie the dual session model in this example. The method will also show signaling routing into the CS domain and further parallel establishment of voice / video in dual-session communication. A prerequisite for the present invention is that the single-session A client is ready to reconfigure to also use the dual-session model, and thus has explicitly registered contacts of CSI and MMtel in CSCF-A. image 3 Divided into 4 signaling groups, namely registration (REGISTRATION), call (CALL), service check (SERVICECHECK) and video (VIDEO). Node entities such as CSCF, RS, etc. are already in figure 2 explained in. The method accordi...

Abstract

The present invention relates to a method to facilitate communication in a telecommunication system, between a first terminal A configured to use a first session model ONE, and a second terminal B configured to use a second session model TWO for media transportation. The method comprises the following steps: - Initiating a service capability check from the first terminal A. - Receiving to the first terminal A capability features ''CSI'' related to the second terminal B. - Establishing that the second terminal B is configured to use the second session model TWO. - Reconfiguring the first terminal A for usage of the second session model TWO.

Description

technical field [0001] The present invention relates to methods and arrangements in a telecommunication system for facilitating communication between a first terminal configured for media transmission using a first session model and a second terminal configured for media transmission using a second session model. Background technique [0002] IP Multimedia Subsystem IMS is a technology defined by the Third Generation Partnership Project 3GPP to provide IP multimedia services on mobile communication networks (3GPP TS 22.228, TS 23.228, TS 24.229, TS 29.228, TS 29.229, TS 29.328 and TS 29.329 version 5 and version 6). IMS provides key features that enrich the end user's person-to-person communication experience by using a standardized IMS service engine that facilitates new rich person-to-person (client-to-person) communication over IP-based networks. Client) communication services and person-to-content (client-to-server) services. The IMS utilizes the Session Initiation Pro...
