Switchboard service system taking mobile phone as extension set and realization method thereof

Abstract

The invention discloses a switchboard service system taking mobile phones as extension sets. The system is realized by adding an IMS (IP Multimedia Subsystem) core network and a mobile phone extension set client on the basis of the existing switchboard service system and mobile phone network structure system. The IMS core network uniformly controls requests of a client and feeds back demands to an NGN/IP exchange network; the mobile phone extension set client comprises a logging module, a dialing module, a call answering module and a switchboard address book checking module. Moreover, the invention also discloses a realization method of the switchboard service system taking the mobile phones as the extension sets. Through the system and the method of the invention, the problem that the switchboard system is limited by the regional distribution of the fixed-line telephones is solved; a high flexibility and low cost enterprise switchboard system is provided to an enterprise; and the employees of the enterprise can access the enterprise switchboard system anywhere and anytime.
