Abstract: A method for setting up data sessions in a communication system is provided. The method comprises registering at least one user equipment with a service provider where after information about media capabilities is communicated between the at least one user equipment and the service provider and then stored. The method comprises further sending a request for a data session with at least one user equipment and using the stored information when setting up the requested data session. A communication system, an application server and a user equipment configured to operate accordingly are also provided.

Abstract: The invention relates to a method in which a message is received to a communication server from a node. The communication server obtains user information with recipient information in the message. The user information comprises user entity state and user entity protocol information. A first protocol is determined to become a preferred protocol based on the user entity protocol information. The delivery of said message is attempted with a delivery mechanism of the preferred protocol. A second protocol is determined to become the preferred protocol with said user entity protocol information upon a failure to deliver said message with said first protocol. The attempting of the delivery of said message is repeated with a delivery mechanism of the preferred protocol.

Abstract: A solution for establishing a session of a real-time media communication service in a communication system comprising at least two separately administered subsystems. The session establishment comprises receiving a request for session initiation, querying subscriber information related to the requested session, and initiating the session according to the queried subscriber information. The invented method comprises detecting that the terminating subscriber does not belong to the same subsystem as the originating subscriber, determining a defined transit server associated with the terminating subscriber, said transit server having access to a subscriber database of the subsystem of the terminating subscriber, and querying subscriber information related to the requested session with a first control message comprising parameters of the requested session to the transit server.

Abstract: The invention relates to a protocol converter (14) and a method utilizing the converter, enabling a wireless connection (13) between a cellular network (11) and a terminal to apply a reduced RTP protocol according to the invention, instead of the RFC 1889 protocol, in order to save communications capacity on speech connections.

Abstract: A method in a communication system for providing communication sessions is provided. The method comprises the steps of registering a user equipment with a data network and then registering the user equipment with a service provider by means of the data network. A data session may then be activated between the user equipment and the service provider via a communication network. Subsequent to the activation, a request can be sent from the user equipment to the service provider for a communication session with at least one other party. The already activated data session can be used for communication between the user equipment and the requested at least one other party. A communication system and an application server configured to operate accordingly are also provided.

Abstract: A method and system forwards a service-related information to network user, wherein at least one new event package directed to a service configuration and/or a de-registration state of the network user is provided at a session control device or a default server or an application server, respectively. A terminal device of the network user initiates a subscription to the new event package. In response thereto, a notification informing about the service configuration and/or the de-registration state of the network user is generated and routed to the terminal device to be made available to the network user.
