The absence assistance system for at least one multimedia-enabled communication system comprising a plurality of packet-oriented client communication systems, in which the packet-oriented client communication systems support at least in part different multimedia services and at least one multimedia service of a packet-oriented client communication system is in each case assigned to at least one communication subscriber, has in each case at least one absence assistance unit per packet-oriented client communication system, the packet-oriented client communication systems being connected to one another via a peer-to-peer transmission protocol. The absence assistance units manage, in the absence of a communication subscriber, the communication connections directed to the absent communication subscriber via the at least one assigned multimedia service.

This application is the US National Stage of International Application No. PCT/EP2006/065630, filed Aug. 24, 2006 and claims the benefit thereof. The International Application claims the benefits of German application No. 10 2005 046 441.6 DE filed Sep. 28, 2005, both of the applications are incorporated by reference herein in their entirety.
The invention relates to an absence assistance system for at least one communication system consisting of a number of packet-oriented client communication systems, wherein the packet-oriented client communication systems support different multimedia services at least in part. Also at least one multimedia service of a packet-oriented client communication system is assigned respectively to at least one communication subscriber.
Absence assistance systems to date have a central absence assistance unit, for example a voicemail server unit arranged centrally within a communication system, by way of which media-specific management takes place, for example by voice services, of the multimedia communication connections received in the absence of the communication subscriber in question. Such central solutions are however technically complex and require cost-intensive server units, which can develop a performance-limiting bottleneck due to their central arrangement in the communication system.
The invention is described in more detail below based on a schematic block circuit diagram with reference to an exemplary embodiment.
The FIGURE shows a schematic diagram of an example of a multimedia-enabled communication system KS, e.g. a private branch exchange for up to 100 communication subscribers for example, linked for example by way of a gateway unit GU to a communication network KN, e.g. a public communication network.
The communication network KN is generally based on time-slot-oriented or packet-oriented transmission technology. The multimedia-enabled communication system KS preferably has a packet-oriented transmission technology. To this end a for example multimedia communication connection KV is implemented within the multimedia-enabled communication system KS by a two-way transmission and receipt of data packets—containing payload and/or signaling information—between a first and second communication terminal. The individual data packets contain among other things information about the destination address of the respective other communication terminal.
To determine the routing within the packet-oriented, multimedia-enabled communication system KS, the gateway unit GU is provided, being configured to determine the routing of data packets containing payload, in particular data packets containing multimedia data, as well as determining the routing of data packets containing signaling data. In particular the gateway unit GU has means for converting data streams received from the communication network KN to suitable data packets and vice versa. The information required for conversion is stored in a peer-to-peer database P2P-DB provided in the gateway unit GU.
