Verfahren und System zum Bereitstellen eines Privat-Fernsprechrufdienstes für Mobilteilnehmer und drahlose Soft-Vermittlungsvorrichtung hierfür

摘要

A method and system for providing a private voice call service to a mobile subscriber are provided. A soft switch in a mobile communication system, upon receipt of an origination message including a private voice request information from a calling MS, transmits to a VPN server a private circuit service request message including a service ID for the private voice call service and the network address information of a caller and called. The VPN server establishes a communication path for edge routers connected to calling and called gateways according to network address information. Thus, voice traffic is transmitted between the calling MS and called MS though the communication path of the VPN.
