CALL MULTIPLE DESTINATION METHOD OF WIRELESS AND WIRE COMPLEX PRIVATE NETWORK

摘要

PURPOSE: A call multiple destination method of a wireless and wire complex private network is provided to response to a call terminated to an extension in the case of absence with a wireless terminal. CONSTITUTION: If an arbitrary user dials a telephone number of a private network wire terminal, a private branch exchange receives a request for terminating to the telephone number(S01). The private branch exchange transmits a message requesting set-up to the corresponding wire terminal in responding to the request and the wire terminal transmits a set-up response message(S02). The private branch exchange searches a database related to subscribers for confirming whether multiple destinations are registered with regard to the wire terminal(S03). If registered, the private branch exchange transmits a message requesting simultaneous ring to the wire terminal and at least one wireless terminal registered for multiple destination(S04). The wire terminal transmits a message responding to the ring request and rings(S05). The wireless terminal also transmits a message responding to the ring request and rings(S06). If at least one wireless terminal hooked off by the user, the corresponding wireless terminal reports to the private branch exchange(S07). The private branch exchange requests hook-on to the wire terminal and the other wireless terminal to be transited to an idle state capable of originating and terminating(S08). The wireless terminal that was hooked-off is transited to a conversation state for performing telephone communication with the originator(S09).
