Telecommunication switching system having transparent wireless features

摘要

A software application program terminating a directory number for all incoming calls directed to the directory number and determining the operations that should be performed with respect to a mobile unit and a telephone station set. The software application program then directs the incoming calls to the mobile unit and telephone station set regardless of where these units are connected to a telecommunication system. An outgoing call from the mobile unit or telephone station set is switched to the software application program which then switches the outgoing call to the destination telephone station set as if the outgoing call had originated at the location of the software application program. Also, the originating directory number used in placing the outgoing call is the directory number associated with the software application program. Two dialing number plans are used: the directory number plan which consists of standard telephone numbers and a secondary dialing plan. The secondary dialing plan is utilized by the software application program to direct and receive calls from the mobile unit and the telephone station set.
