That is, in the conventional system (see FIG. 2), when there is origination request from the mobile terminal 4 to the base station 2 2, outgoing request signal is edited by the exchange station for signal editing apparatus 13 of the base station 2 2. The transmission request signal is transmitted to the exchange station 1 1 by the exchange station signal transmission device 14 of the base station 2 2 . The origination request signal is received by the exchange 1 1 to the base station signal receiver 16, is analyzed by the received signal analysis unit 12 of the switching center 1 1, the communication line between the exchange 1 1 and the base station 2 2 determines that it is necessary to set the switching center 1 by one of the base station for signal editing apparatus 11 edits the communication line assignment request signal, the switching center 1 1 of base station 2 2 by the base station for signal transmission apparatus 15
Is transmitted to the signal receiving device 10 for the exchange. The communication line allocation request signal is received by the received signal analyzer 12 of the base station 2 2.
When the base station 2 2 determines that there is a free wireless communication line in the base station 2 2 by the presence / absence determining device 18 of the base station 2 2 , the exchange signal editing device 13 of the base station 2 2 causes the free wireless communication line. A signal indicating that there is a signal is edited, and the signal is transmitted to the switching station signal transmitter 14 of the base station 2 2.
It is sent to the switching center 1 1 to the base station signal receiving apparatus 16 by. The signal is analyzed by the received signal analysis unit 12 of the switching center 1 1, as a result, the communication line to the base station 1 1 is set by the communication line setting unit 17 of the switching station 1 1. Further, switching center 1 1 to the base station signal editing apparatus 1

とを特徴とする。According to the present invention, when a base station (first base station) for which a call origination request is set has no available wireless communication line, the base station establishes a mobile terminal and a wireless communication line. Check the peripheral base stations that can be set, notify the base station number to the upper exchange (first exchange), and that base station (second base station) is under the control of other exchanges. In the case of a base station, the first exchange station passes through a superordinate exchange station (second exchange station) of the second base station, and then the first exchange station-the second exchange station-the second base station. A feature is that a communication line is set up between the station and the mobile terminal.

可能となる。According to the present invention, even if there is no free channel in the base station for controlling outgoing / incoming calls, the communication channel can be set up by using the free channel of another base station, so that the call loss is reduced. At the same time, the utilization rate of the frequency assigned to the base station can be increased, so that the frequency can be effectively used.

信回線を設定する通信回線設定方法。1. A plurality of exchange stations connected by a communication line and a control line, and a plurality of base stations connected by the communication line and the control line for managing the air-tightness of a wireless line are provided under each exchange station. , In a mobile communication system in which a mobile terminal can communicate in a radio zone controlled by the base station, when a certain switching center requests a communication line allocation to a lower base station, the base Station sends a signal to another base station to inquire about the availability of a vacant wireless communication line to the upper switching station, and the upper switching station and the upper switching station of the inquiry destination base station send the inquiry signal to the inquiry destination base station. The base station of the inquiry destination sends an inquiry response signal to the higher-level switching center when the base station of the inquiry destination has a free wireless communication line, and the higher-level switching center and the higher-level switching center of the base station of the inquiry source. Inquires the inquiry response signal It relays to the base station, the base station of the inquiry source notifies the upper exchange station of the base station number with the idle wireless communication line, and the upper exchange station exchanges with the upper station of the base station with the idle wireless communication line. Communication line setting method for setting the communication line to and the communication line to the base station.
