摘要
Switching points in current voice telephony networks (PSTN/ISDN) deal with the control of links and useful channels. Next generation networks which are designed for voice and data work according to the principle of separation in the control of links and useful channels. Different network elements are used to control links and useful channels. Link control is carried out by soft switches which communicate by means of a suitable protocol with media gateways controlling the useful channel. A plurality of services are implemented in existing networks, said services continuing to be needed. This results in the following problem: the new development or porting of the software controlling said services required for the soft switches is extremely heavy and very complex. According to the invention, said problem is solved by means of a software model which replicates classic hardware used in next generation networks, said software model being configured in such a way that the control software of a network node used in a conventional telephone network controls the components of the next generation network replacing said classic hardware in conjunction with a soft switch by means of a control protocol.
