WIRED/WIRELESS INTERWORKING METHOD OF WIRED/WIRELESS TELEPHONE INTERWORKING SERVICE SYSTEM

摘要

PURPOSE: A wired/wireless interworking method of a wired/wireless telephone interworking service system is provided to operate a wired telephone service-type virtual wired telephone number, and to transmit a caller ID to the virtual wired telephone number, so that an outer subscriber can receive a call incoming with the wired telephone number through a self wireless terminal. CONSTITUTION: A wireless terminal calls a telephone number of other party(S21). An origination signal generated from the wireless terminal is transmitted to a mobile gateway via a pBTS and a pBSC(S22). The pBSC changes a caller ID assigned to the wireless terminal into a virtual wired number(S23). The mobile gateway decides whether the origination number is an outer origination number(S24). If so, the mobile gateway stores a call only in a message, and transmits the message to a wired MSC(S25). The wired MSC calls an outer subscriber corresponding to the telephone number through a PSTN(S26).
