[0103] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0104] The basic principle of the present invention is to introduce a new network node AGCF in the IMS defined by the 3GPP R5 / R6 standard. Through the control of access equipment, PSTN users and ISDN users are connected to the IMS domain, thereby providing it with PSTN and ISDN services. The functions of each network node of the IMS defined by the 3GPP standard remain unchanged. Because the AGCF shields the difference of access users, these access users can be regarded as users in the IMS domain, just like 3G mobile users. PSTN and ISDN services can be centrally controlled by PSTN / ISDN Simulation AS in IMS, or AGCF can complete the control of basic services and supplementary services, and PSTN / ISDN Simulation AS can complete the control of extended value-added serv...
