The invention includes a system for processing telecommunications signaling. Signaling for a call is received into a signaling processor. The signaling processor processes the call and generates new signaling incorporating the processing. The new signaling is transferred to network elements as appropriate. The signaling processor is not coupled to a switch matrix and only communicates with the network elements over signaling links.

A generic call server in a hybrid 2G/3G telecommunications network having a plurality of network components that utilize a plurality of different signaling protocols. The call server performs call-control functions and interfaces between any two network components selected from the plurality of components. A Generic Call-control State Machine (GCSM) performs call-control functions that are common to all of the protocols. A plurality of external signaling systems interface between the GCSM and the network components and perform call-control functions that are specific to each protocol. The generic call server may also include a Media Gateway (MGW) Handler that acts as a media signaling protocol handling server and interfaces between the GCSM and a media gateway.
ATM is used as a transport and switching mechanism in a hybrid STM/ATM network while the signaling remains normal narrowband signaling. The narrowband signaling is transported on permanent paths over ATM connections, and the narrowband speech channels are transported on ATM and switched on a "Per call basis" (on-demand) through an ATM switch. A translator formats a call-setup-related signaling message into ATM cells so that the signaling message can be routed through an ATM switch to a circuit switched (STM) node. The circuit switched node (PSTN/ISDN) sets up a physical connection for the call and generates a further signaling message therefor that relates to the physical connection. The ATM switch routes an ATM cell-formatted version of the further signaling message to another ATM switch over an ATM physical interface. Thus, the ATM switch switches both narrowband traffic and signaling for the call over the ATM physical interface.
The invention relates to a system and method for changing protocol parameters of a signaling protocol for the implementation of services in an Intelligent Network concept with user data transfer via a packet network. Resources are provided in a service control point for parameter changes to be made in the context of the services to the signaling protocol used. Implementation of a service, which requires a change to a protocol parameter in the signaling protocol, correspondingly adapted intelligent network application part procedures are used by a service switching point to trigger the parameter changes to be made in an service control point and the change to the protocol parameter is effected by the service control point in the service switching point. The invention has the advantage that it allows parameter changes, which are not provided in the ISDN user part because of their relationship with the packet network.
