Abstract: A method of exchanging content between a User Equipment, UE, and an Application Server, AS, of an IP Multimedia Subsystem, IMS, or between the UE and a peer UE. The method comprises establishing a Session Initiation Protocol, SIP, session between said messaging resource function and the AS; establishing a Message Session Relay Protocol, MSRP, session between the UE and a messaging resource function of the IMS; and exchanging content between the first mentioned UE and the messaging resource function in messages sent over the established MSRP session.

Abstract: The invention relates to a method carried out by a service control entity to set up a communication path for exchange of service control messages with a service application entity (200) in a mobile communications network for controlling an application of a service, by the service application entity (200), to a media data flow, the media data flow being established between the service control entity (100, 300) and a remote end. A first message is transmitted on a service control channel, the first message comprising as a destination address an address of the remote end, wherein offer data is added to the transmitted first message, the offer data including an indicator indicating that the service control entity is configured to support a communication path on a media data plane of the media data flow based on Real Time Transport Control Protocol, RTCP, service control messages.

Abstract: The invention relates to a method, by an initiating entity (100, 200, 210), to initiate the set up of one or more communication channels for exchange of information between the initiating entity and one or more responding entities (100, 200, 210). The method comprises the following steps: A first message is transmitted on an end-to-end control channel between a first entity (100) and a second entity. The first message comprises as a destination address a second entity address, wherein offer data is added to the transmitted first message. The offer data indicates that the initiating entity (100, 200, 210) is configured to support one or more communication channels and the offer data comprise an address at which the initiating entity is configured to receive the information. Then, a second message is received on the end-to-end control channel, the second message comprising as destination address an address of the first entity.
