Next, the full duplex channel setting operation will be explained with reference to FIGS. 4 and 5.

(1) Connection of extension telephone Tl”-Tm to personal radio terminals P1 to PN (i) Calling operation For example, extension telephone 'ri of extension telephone group 13, telephone number assigned to the called personal radio terminal. For example °
When ゛○×△×″ is dialed, the exchange 10 dials the telephone number Pa○× through the subscriber circuit 81.
” and sends it to processor 11. Processor 1
1 analyzes this telephone number and confirms that the called telephone number is, for example, a personal radio terminal Pl, and then the personal subscriber circuit group 15 seizes, for example, a personal subscriber circuit PSL as a vacant personal subscriber circuit.

Next, the processor 11.

For example, "12345"'Th is searched as the calling group code corresponding to the telephone number "XX to ×", and the result is sent via the control section 44 shown in FIG. No group code memory °' 12
345''.Next, the control unit 44 switches the antenna switching circuit 41b to the transmitting side and emits an open side 1-channel radio wave from the transmitting unit 42b via the antenna 41a'&.

Below, please follow the steps of the Personal Musou method to
The wireless terminal Pl to which Δ×'' has been assigned is captured. As a result, the incoming call light (not shown) of the wireless terminal P"1 lights up and an audible signal sounds.

As a result, when the called subscriber of the personal radio terminal P1 goes off-hook from the four-wire telephone 35 shown in FIG.
0 detects all of this, waits until the radio wave emission from the exchange 10 side stops, and then starts the transmitter 31b'e via the logic section 31ai of the AI-based personal radio 31. The antenna 21a emits a smudge wave on the designated communication channel. This radio wave is transferred to the personal subscriber circuit PS.
B of l.

When the system personal radio 42 receives the call via the antenna switching circuit 41b, it lights up an incoming call indicator (not shown) and notifies the control unit 44.

In response to this, the control unit 44 connects the antenna 41a to the receiving unit 4.
The switch is fixed to 2C, and the transmitter 42b is stopped.

That being said, personal wireless terminal Pl exchange iso 10
A communication path in the direction is set.

Next, the control aj unit 44 of the personal subscriber circuit PS
"12345" k is again set in the group code memory (not shown) of the logic section 43a of the second-system personal radio 43, the antenna switching circuit 41c is switched to the transmitting side, and the control channel radio wave is emitted. Note that the communication channel designated by this control channel is excluded from the communication channel currently being used by the B1-based personal radio according to the procedure of the personal radio system.

By this control child wave, the personal wireless terminal P
] is captured, the A2-based personal radio 32 turns on all incoming call indicator lights (not shown) and sends out an air signal. As a result, the control unit 30 of the personal wireless terminal P+
via the logic section 31a and transmitter section 31b'i of the +AI personal radio device 31, notifies the exchange 10 side that a call path has been set from the exchange 10 to the personal wireless terminal P1, and at the same time transmits the transmission manually. AI switching circuit 33a
A receiving output switching circuit 33 is installed on the side of the system personal radio device 31.
b on the A2-based personal radio device 32 side.

As a result, the four-wire telephone 35 is connected to the set communication path via the terminal switching circuit 34.

According to the above, when the communication path from the exchange 10 to the personal wireless terminal P1 and from the personal wireless terminal PI to the exchange 10 is established, the glossosaur 11 transmits the ringback tone or connection tone that was being sent to the calling telephone. I refuse. Note that if the call path cannot be set, this is used as a busy tone.

(11) Call and call termination operations When a second call path is installed, the call state is similar to that of a normal exchange connection.

To end the call, use the 4-wire telephone 3 on the personal wireless terminal Pl side.
Personal jJ captured by 5's on-hook
By disconnecting the air that was being sent out from the D-person circuit PS, the switching station 10 enters the end-of-call operation.

Switch 1 is switched on due to the on-hook of the calling extension telephone T1.
0 enters call clearing operation and the personal subscriber circuit PS is opened.

As for the call from the extension telephone TI to the personal wireless terminal P1 as described above.

The specific standby of the called personal radio terminal P1 is determined by the group code, for example "'12345".

Since communication paths are set up from the personal radio terminal P to the exchange 10 and from the exchange 10 to the personal radio terminal P1.

(2) Connection between personal radio terminal P]~pN and extension telephones 1'1 to T1 (1) Calling operation Any personal radio terminal, for example, personal radio terminal Pi. Among extension telephones T1 to Tm, for example, an extension telephone To make a call to Tm, first use personal wireless terminal P1.
For example, the personal subscriber circuit PS of the exchange 10
For example, °'54321''' is the representative standby group code for I.
It is set in the kA+ personal radio device 31 to emit control channel radio waves. Following the procedure of the personal radio system, the B1 system personal radio 42 of the partial subscriber circuit PSl is captured, and thus the personal 7J[]
The incoming call indicator light (not shown) of the human observer circuit S lights up,
And it sends out the earthly energy.

The exchange 10 considers this transmitted radio signal to be a call originating from the personal terminal, and then calls the personal wireless terminal P1.
Preparations are made to receive the PB multiplied signal sent from. However, since the call path setting has not yet been completed, the exchange 10 does not emit dialable radio waves to the personal wireless terminal Pl. Then, the personal wireless terminal p is connected to the called extension telephone T.
For example, a PB multiple signal of "4321" is sent as the telephone number of m.

When the personal wireless terminal Pl finishes transmitting this PB-multiple signal, it switches to the receiving state.

The personal subscriber circuit Psi accumulates the signal in the PB double signal control section 44, switches the antenna switching circuit 41b to the transmitting side, and emits the connection tone to the wireless terminal PI through the antenna 41a.

As described above, a communication path from the personal jJO circuit PS1 to the personal wireless terminal P1 is established.

The control unit 44 of the personal subscriber circuit PS+ connects A of the partial wireless terminal P via the above-mentioned set communication path.
The second system personal radio 32 again sets the group code "54321" for representative standby and instructs the emission of control channel radio waves.

In this case, the call channel specified by the control channel is
According to the procedure of the personal radio system, a communication channel different from the communication channel for the personal subscriber circuit PSI to the personal radio terminal P1 is specified.

As a result, when the B2 personal radio 43 of the partial subscriber circuit PS is captured, an incoming call indicator light (not shown) is turned on.

It notifies the controller 44 of the personal subscriber circuit PS that a communication path has been established from the personal wireless terminal PI to the personal subscriber circuit PS1. Accordingly, the control unit 44 instructs the personal wireless terminal P1 to retransmit the PB double signal of the telephone number "4321" of the extension telephone Tm stored in the personal radio terminal P1.

The control unit 44 compares the retransmitted PB double signal with the originally received PB double signal, confirms that they match, and transmits this P
The signal is transferred to the B-fold signal exchanger 10. At the same time, a ringback tone is sent to the personal wireless terminal PI.

In this case, the connection tone may be sent first and then changed to the ringback tone. If the called extension telephone Tm is busy, the ringback tone is changed to a busy tone.

(11) Call and call termination operations Regarding call and call termination operations, the above-mentioned (1) Extensions (telephones T1 to Tm) to non-nonal wireless terminals P1 to Tm
The operating procedure is the same as for a call to a PN.

(3) Personal radio terminals pl-pN Yojino;-Sonal Regarding the connection and calling operations of the radio terminals P1 to Prn, (2) Personal radio terminal P1
-Call from pN to extension telephone Tl-Tm (1)
This is the same as calling operation.

Regarding the incoming call operation, (1) Extension telephones T1 to Tm
(1) of connection to personal wireless terminals P1 to pN
This is the same as calling operation.

Note that this call can also be carried out as a normal personal radio without using the control unit 30 of the personal radio terminals P1 to pN and without involving the exchange 10. However, in this case, the group code must be known in advance for the called personal radio to stand by.
