Abstract

PURPOSE: To attain the reception of an order entry service by converting a PB signal from a radio terminal equipment into an MF signal and sending the converted signal to a communication circuit so as to transmit a content of a PB signal from a terminal equipment during communication to a terminal equipment in an exchange network. CONSTITUTION: A radio terminal equipment dials a number of a terminal equipment accommodated in an exchange network in terms of a PB signal and makes connection and becomes a state of communication. In this state, when a PB signal code is sent from the radio terminal equipment, it is received by a controller of a personal communication service providing device. The controller discriminates the communication state of a terminal equipment 5 and transfers the PB signal code to an MF signal generating circuit 10 and allows a selector 11 to connect a busy channel B1 or B2 to the circuit 10. The circuit 10 generates a digitized MF signal equivalent to the PB signal from the controller and sends the digital signal to an exchange network circuit via an I interface channel control circuit 12, the exchange network converts the MF signal into an analog multi-frequency signal or sends the digital MF signal to a terminal equipment accommodated in the exchange network as it is, where the signal is converted into the PB code for the processing.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal communication system for providing communication between a mobile wireless terminal such as a personal handy phone (PHS) and a terminal accommodated in a switching network.

[0002]

2. Description of the Related Art A PHS PB signal code does not use a communication channel between a wireless terminal and a wireless base station and between a wireless base station and a personal communication service providing apparatus even during communication. Is transmitted in code format using a control channel. On the other hand, in the switching network, the PB signal during communication is transmitted using the communication line. Therefore, the PB from the wireless terminal to the computer center for ticket reservation, etc.
It was not possible to perform data communication such as placing an order using the signal code.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a service providing apparatus for performing data communication during communication by a PB signal code from a wireless terminal. is there.

[0004]

A personal communication service providing apparatus according to the present invention includes means for receiving and interpreting a PB signal code transmitted from a wireless terminal via a control channel via a wireless base station, and the PB signal code. Of the P from the wireless terminal.
The B signal code is transferred to the switching network line in which the wireless terminal is communicating.
It is transmitted as an F signal and enables communication by a PB signal code between a wireless terminal and a computer terminal or the like accommodated in a switching network. Here, the PB signal code is a digital signal code which is a code of a signal transmitted to the communication line when the wireless terminal is operated.

[0005]

The personal communication service providing device takes in the PB signal code transmitted from the wireless terminal via the wireless base station via the control channel into the control device of the service providing device, interprets the contents of the PB signal, and The MF signal transmission command corresponding to the signal is issued. Since the built-in MF signal sending circuit is always connected to the communication line in the switching network interface device, the MF signal according to the instruction can be sent to the communication line at any time. Therefore, even during communication, M
The F signal can be issued, and the wireless terminal can access the computer center and place an order with the PB signal code.

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a block diagram of a personal communication system according to the present invention, in which 1 is an exchange network, an existing telephone network,
2 is a terminal such as a computer accommodated in the telephone network, 3 is a personal communication service providing apparatus connected to the exchange network, 4
Is a wireless base station, 5 is a movable wireless terminal, 6 to 9 are devices in a personal communication service providing device, 6 is a control device for controlling the entire service control device, and 7 is a subscriber interface with a switching network. Is a switch network line interface device for controlling the switch, 8 is a switch for switching between the line of the switch network and the base station line, and 9 is a base station line interface device for controlling the interface with the base station. FIG. 2 shows a part of the configuration of the switching network line interface device, and 10 is an M for generating an MF signal (multifrequency signal) in response to an instruction from the control device.
An F signal generation circuit, 11 is a selector for selecting a communication channel from the switch and an output from the MF signal generation circuit, 12
Is an I interface line control circuit for controlling the I interface line of the switching network.

First, the wireless terminal 5 dials the number of the terminal 2 by the PB signal in order to connect to the terminal 2 of the switching network.
The PB signal is transmitted in the code format in the control channel between the wireless section and the wireless base station and the personal communication service providing device, and is taken into the control device 6 of the personal communication service control device. The control device 6 transfers the PB signal code received from the wireless terminal to the I interface line control circuit 12, and instructs the switching network to perform a calling operation. Calling signal is I
It is transmitted to the switching network through the control channel of the interface line, and by the switching operation, it is connected to the terminal 2 and is in communication. Next, when the PB signal code is transmitted from the wireless terminal,
Between the wireless section and the wireless base station and the personal communication service providing device, a control channel is transmitted and taken into the control device 6 of the service control device. When the control device determines that the wireless terminal is communicating, the control device sets the PB signal code to MF.
The channel (B1 or B2) in communication with the selector 11 is connected to the MF signal generating circuit 10 while being transferred to the signal generating circuit 10. The MF signal generation circuit 10 generates a digitized MF signal corresponding to the PB signal transferred from the control device, and the I interface line control circuit 1
2 to the switching network. If necessary, the MF signal is converted into an analog multi-frequency signal in the switching network and transmitted to the terminal, or the MF signal is transmitted as it is to the terminal in digital form. The terminal receives the MF signal, returns it to the PB code, interprets it, and performs processing according to it.

In the present embodiment, the line interface of the switching network is the I interface, but even in the case of an analog line, the present invention can be applied if the output from the MF signal generating circuit is analog.

[0009]

As described above, according to the present invention, the MF signal generating circuit is provided in the switching network line interface device of the personal communication service providing device, and the P from the wireless terminal is connected.
Since the B signal is converted into the MF signal and sent out to the communication line, the contents of the PB signal from the wireless terminal can be delivered to the terminal accommodated in the switching network during the communication, and the wireless terminal can reserve the ticket. There is an effect that you can receive order entry service such as.
