A server device configured to provide a content aggregation service. The server device comprises a first transceiver unit configured to communicate with a terminal, a second transceiver unit configured to communicate with content network sources, a memory for storing a resource list of addresses of the content network sources, and a content aggregation processor operably connected with the first and second transceiver and the memory, and configured to fetch content from the addresses of the content network sources as well as to aggregate the fetched content into a notification message to the terminal.

Content aggregation service for mobile environment

A method of setting up a session between peer user terminals of a communication system, wherein at least one of the user terminals is a dual-mode terminal having access to both an IP-based packet-switched access network and a circuit-switched access network, and the session extends at least in part across the circuit-switched access network. One of the user terminals initiates the session by sending Session Initiation Protocol (SIP) signaling to a SIP server over the IP-based network. The SIP server sends a notification to a gateway server to establish one or more conversational bearers. The gateway server then sends a callback telephone number to the dual-mode terminal. The dual-mode terminal then calls the callback number to establish a circuit-switched session with the gateway server.

Conversational bearer negotiation

A method of enabling a terminalcoupled to a GSTNto join an Internet based presence service facilitated by a presence server. The method comprises establishing a telephone connection between said terminaland an intermediate servervia the GSTN, as a result of said connection, establishing a proxy entity corresponding to said terminalat said intermediate serverand registering the proxy entity with the presence servervia the Internet, and exchanging presence service messages between the presence serverand the proxy entity at the intermediate servervia the Internet and between the proxy entity and said terminalvia the GSTN network

Communication networks

A method of setting up a call between first and second nodes of a communication system when the call extends across a circuit switched access network and a packet switched backbone network interconnected by a Media Gateway. A control node obtains from a Home Subscriber Server, the identity of a Media Gateway Control Function controlling that Media Gateway which will terminate the call within the circuit switched access network. The first node calls an access number notified to it by the Media Gateway Control Function, and as part of the call setup procedure, the identity of the Media Gateway selected to terminate the call is communicated to the second node.
