Abstract:
A wireless local loop system, comprising:a telephone arranged in a house for receiving incoming telephonic information and outputting outgoing telephonic information;a telephone circuit network for transmitting the incoming telephonic information to the telephone and transmitting the outgoing telephonic information output from the telephone to a communication partner;a fixed subscriber unit, connected with the telephone through a telephone cord in the house, for receiving the incoming telephonic information transmitted from the telephone circuit network through a radio communication path, transferring the incoming telephonic information to the telephone through the telephone cord, receiving the outgoing telephonic information from the telephone through the telephone cord and outputting the outgoing telephonic information to the radio communication path;a wireless base station for receiving the incoming telephonic information transmitted from the telephone circuit network, transmitting the incoming telephonic information to the fixed subscriber unit through the radio communication path, receiving the outgoing telephonic information from the fixed subscriber unit through the radio communication path and transmitting the outgoing telephonic information to the telephone circuit network; anda base station managing apparatus, connecting the wireless base station and the telephone circuit network through a wiring communication path, for transmitting the incoming telephonic information received by the wireless base station to the telephone circuit network through the wiring communication path, transmitting the outgoing telephonic information received from the telephone circuit network to the wireless base station through the wiring communication path and managing the wireless base station to make the wireless base station perform an incoming call sequence with the fixed subscriber unit and to perform a telephonic communication between the user and the communication partner, an incoming call being transmitted from the base station managing apparatus to the fixed subscriber unit through the wireless base station in the incoming call sequence, an incoming call response signal indicating the reception of the incoming call being transmitted from the fixed subscriber unit to the base station managing apparatus through the wireless base station in the incoming call sequence, an incoming call signal being transmitted from the fixed subscriber unit to the telephone in the incoming call sequence to inform the user of the incoming call, and the base station managing apparatus comprising:pseudo-incoming call outputting means for outputting a pseudo-incoming call to the fixed subscriber unit through the wireless base station and the radio communication path to make the fixed subscriber unit output the incoming call response signal to the base station managing apparatus through the wireless base station in the same manner as in the incoming call sequence;incoming call sequence interrupting means for outputting a sequence interrupting signal to the fixed subscriber unit through the wireless base station according to the incoming call response signal received by the base station managing apparatus to prevent the fixed subscriber unit outputting the incoming call signal to the telephone and to interrupt the incoming call sequence; andoperational condition informing means for informing the telephone circuit network according to the incoming call response signal received by the base station managing apparatus that the fixed subscriber unit is normally operated to perform the telephonic communication.
