Abstract: Telecommunication systems with packet-switched multimedia terminals and nodes for packet-switched multimedia sessions and with servers for exchanging multimedia signaling information for the packet-switched multimedia sessions and with terminating units are provided with gateways for in response to transferral messages originating from the packet-switched multimedia terminals and arriving at the servers transferring packet-switched multimedia sessions between packet-switched multimedia terminals and nodes to circuit-switched calls between gateways and circuit-switched terminals via switches, to continue possibly interrupted sessions via replacing calls. The servers send invitation messages to gateways, which send setup messages to switches for setting up circuit-switched calls via partly alternative communication paths. The servers send information messages to terminating units for bringing the terminating units from session level to call level.

Abstract: Telecommunication systems should be able to handle different protocols. Thereto, with a first protocol being Internet Protocol v6 using 128-bit addresses of a first kind and with a second protocol being Internet Protocol v4 using 32-bit addresses of a second kind, an access system is provided with a generating section for, in response to an address of one kind, generating a corresponding address of an other kind for a terminal-to-terminal communication and independently of which terminal has initiated said terminal-to-terminal communication. For a set-up phase, a replacing section replaces addresses of a second kind by corresponding addresses of a first kind, and an adding section adds, in addition to addresses of a first kind, corresponding addresses of a second kind, in set-up messages. For a communication phase, activating sections activate translating sections, which translating sections translate addresses of one kind into addresses of an other kind, in packets.

Abstract: A method for charging Internet protocol multimedia communication sessions within a telecommunication system is disclosed. Charging records are generated by a control element in the system with a same correlation identifier for all the charging records produced for a communication session between parties. A multi-sided correlation identifier and a charging information field containing information related to a determined charging plan is passed via session control protocol between control elements. The charging plan information, along with the multi-sided correlation identifier, is propagated between control elements in the system. The multi-sided correlation identifier and selected charging data is included in each charging record generated for the communication session by each control element. The charge for the communication session is calculated on the basis of the selected charging data received by via the charging records including the multi-sided correlation identifier.
