FIG. 2B shows location registration data of a plurality of wireless terminals 16. In the registration data 33, the RC group in which the wireless terminal RTj is located is recorded at the address Cj modified by the address Bj of the wireless terminal (RTj) in FIG.

In FIG. 1, the central control unit 13 has a bus 1
5 periodically scans the radio base controller 19, monitors the identification information including the radio terminal identifier transmitted by the radio terminal 16, and receives the location registration information. Update 3

FIG. 7 shows the central control unit 13 and the wireless terminal 16.
It shows a signal transmitted and received between them. As shown in the signal format 40, the signal format is composed of a receiving side identifier (ID), a command, and a transmitting side identifier (ID). As signal forms, there are an RT start signal 41, a start completion signal 42, a calling signal 43, and a response signal 44. .

The central controller 13 controls connection between the emergency telephone 18 and the emergency reception desk controller 24 and connection between the emergency reception desk controller 24 and the radio base station 17 via the network 12. When the central controller 13 detects the call information of the emergency telephone 18 from the emergency telephone controller 20 via the bus 15, the central controller 13 connects the emergency telephone controller 20 and the emergency reception desk controller 24 via the network 12 and makes a call. The emergency telephone 18 connected to the emergency reception desk 25 is connected. Further, the transmission floor indicator light 23 indicating the position of the emergency telephone which transmitted the signal to the transmission floor indicator light control device 22 via the bus 15 is turned on. The display unit displays the position of the calling emergency telephone in the RC group.

Next, the operation of the radio terminal incoming call control system of the present embodiment will be described with reference to FIGS. The emergency telephone 18 shown in FIG. The receptionist of the emergency reception desk 25 confirms the RC group where the caller is located by displaying the transmission floor indicator light 23 and the LCD (liquid crystal) display unit of the emergency reception desk 25.

FIG. 3 is a state transition diagram showing dial transmission from the emergency reception board 25. In the figure, the acceptor is, for example, an RC group-designated calling special number and the RC where the caller is located.
Dial the group number. Central control device 1 of FIG.
3 analyzes the dial information received from the emergency reception desk 25, searches the location registration data 33 of the wireless terminal 16 in FIG. 2 (b), finds the RC group number where the caller is located, and the RC group where the caller is located. If there is no number, the RC group number designated by the central control device 13, for example, the RC group number closest to the RC group number where the caller is located is extracted. Then, a registration data 3 2 addresses Bj shown in FIG. 2 (c) from the address Cj, extracts the wireless terminal identifier of the wireless terminal 16 address Bj.
Further, the central control device 13 determines, from the registration data 31 of the radio base control device 19 corresponding to the group in FIG. 2A, the accommodation position of the radio base control device 19 corresponding to the RC group of the caller and the radio station identifier thereof. extracted, instructs activation of the wireless terminal 1 6 to the radio base station 17 connected thereto via the radio base controller 19 of the identifier.

FIG. 4 is a state transition diagram showing that RT is being started. 7, the wireless base station 17 transmits an RT start signal 41 shown in FIG. 7 by radio waves in accordance with an instruction from the central control device 13 shown in FIG. When the wireless terminal 16 receives this,
The wireless terminal identifier of the RT activation signal 41 is compared with the stored wireless terminal identifier, and when they match, the RT activation completion signal 42 of FIG. 4 is transmitted. The information of the completion of the RT activation is received by the central controller 13 from the radio base station (RC) 17 via the radio base controller 19. The central control device 13
The wireless base station 17 is instructed to call the wireless terminal 16 via the wireless base controller 19, and the emergency reception desk controller 24
