This interworking is normally carried out by means of an interworking server, which implements a one-to-one transcoding of the voice signals where necessary.
The problem that arises in this context is when and how it is decided and controlled within a network whether voice is implemented via the conventional CS service or via VoIP. In the known solutions this is done using predefined static scenarios.
Printed publication GB 2 321 158 A discloses a network architecture for carrying out both voice and data service over the Internet, wherein the network structure has a multiplicity of Internet base stations deployed each having high-capacity trunk connections with central offices for Internet and ISDN access and wireless transceivers for subscriber voice and data communication, in which PCM
data from the central office is passed from the PCM gateway to a PSTN and vice versa, and for sending packet-oriented data, from the data packet gateway and vice versa to an Internet gateway.
It cannot be gathered from this printed publication that operator-specific parameters and user equipment properties are incorporated based on an additional exchange of information.
Printed publication WO 2006/044654 discloses a method and system for transmitting voice traffic via a gateway device, wherein the gateway receives an indication of an attempted initiation of a connection in order to activate a connection to a contact, and a connection option is chosen from a group of available connection options of predefined criteria, wherein the attempted communication for completion is controlled with the contact using the selected connection option.

Such a packet-switched communication is carried out by means of various protocols, such as for example 2G or 3G, in which it is necessary for a handoff from CS communication to PS
communication that the two communication systems are capable of cooperating with one another.
This cooperation for the handoff between these systems is known from the prior art as so-called interworking, which is carried out by means of an interworking server.
From a mobile user equipment (UE) voice signals are transmitted circuit-switched (1, 2) or packet-switched (3, 4, 5) to an interworking server in the particular access network (10).
This server recognizes from the incoming voice signals whether the voice signals are circuit-switched (1,2) or packet-switched (3, 4, 5).
After the appropriate transcoding in the access network (10) these voice signals are relayed to the appropriate network either circuit-switched CS (11) or packet-switched PS
(12).
It is possible to relay such voice signals to a service portal (14) comprising a virtual network VPN
(15), an intelligent network IN (16), or an IP multimedia subsystem IMS (17).
Additionally, the voice signals can be relayed as circuit-switched CS (11) or packet switched PS
(12) voice signals to a mobile radio network PLMN (18).
Additionally, the voice signals can be relayed as circuit-switched CS (11) signals to a public switched telephone network PSTN (19) or as packet switched PS (12) signals to the Internet (20).

access network (24) or from a PS access network (25) directly to the Internet (20), to the public switched telephone network (19), to a service portal (14), or to a mobile radio network (18), with the controller (23) dynamically making the decision to relay the voice signals to the respective network by means of the aforementioned decision criteria.
It is important in this context that the respective voice signals are transmitted to the controller (23) via an access network (24) with circuit switched CS voice signals or from an access network (25) with packet-oriented PS voice signals.
