Private branch radio extension terminating system
First Claim
1. A private branch radio extension terminating system comprising:
- a plurality of radio base station units each capable of accommodating a plurality of private branch radio extension terminals within a radio wave rage, at least one line control unit for controlling said radio base units, and a private electronic branch exchange including a time-division switch for accommodating said line control unit, a central processing unit for controlling said private branch radio extension terminals via said line control unit and said base station units, and a storage unit for storing various data and programs;
wherein said central processing unit determines which of said radio base station units is to transmit a ringing signal for calling a selected private branch radio extension terminal, on the basis of position registration information and route information about said private branch radio extension terminal stored in said storage unit, and transmits a ringing signal transmission command to each said determined radio base station unit; and
wherein when said private branch radio extension terminal moves, said central processing unit updates the position registration information and the route information about said private branch radio extension terminal by using registered information from said private branch radio extension terminal.

Abstract
A private branch radio extension terminating system includes radio base station units, at least one line control unit, and a central processing unit. The radio base station units are installed in a plurality of places each capable of accommodating a plurality of private branch radio extension terminals within its radio wave range. The line control unit controls the radio base station units. The private electronic branch exchange includes a time-division switch for accommodating the line control unit, a central processing unit for controlling the private branch radio extension terminals via the line control unit and the base station units, and a storage unit for storing various data and programs. The central processing unit determines the radio base station unit, which is to transmit a ringing signal for calling the private branch radio extension terminal, on the basis of position registration information and route information about the private branch radio extension terminal, and transmits a ringing signal transmission command to the radio base station unit.
