JPH04322547A - Public adaptor for simple mobile radio - Google Patents

Abstract

PURPOSE:To allow each mobile set to simply attach a charging adaptor and to display a talking charge when a utility charge is collected from each mobile set in the simple mobile radio system through a public network. CONSTITUTION:Mutual incoming and outgoing signals are monitored between a key operation section Cu outputting a dial signal of a telephone set of each mobile set 100 and a control section Tu sending the dial signal to a radio base station 200 for talking with an opposite telephone set. The adaptor is provided with an adaptor control section 1 detecting a dial signal of a telephone set of the mobile set to output a talking control signal, a toll station number monitor section 2 monitoring a toll station number of a telephone number of a call destination of the telephone set with the control signal and a charging information storage table 3 storing charging information for each toll station number in advance. The charge information storage table relating to a toll station number of a telephone number of the call destination of each mobile set monitored by the toll station number monitor section is selected and a talking charge is displayed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple mobile radio system, and more particularly to a billing adapter for allowing individual mobile devices to use a public network for a fee.

[0002] When a mobile device is used in a public network for which a call fee is charged, problems arise in how to transfer billing information and how to charge. Conventionally, when a mobile phone is used in a public network, for example, when a car phone is installed in a taxi, a system is used to generate billing information in a switching control station that connects the communication line with the other party. It sends and receives billing information to and from the mobile device. That is, a billing control system that generates and controls this billing information is required within the switching control station. However, at present, simple mobile radio systems are not fully equipped with such charging control systems, but there is a strong demand from users of these simple mobile radio systems to use them like a public network. For this reason, it is desired to realize a simple mobile radio adapter that can easily and inexpensively display call charges on a public network.

2. Description of the Related Art In a conventional charging method in a mobile radio system, as shown in FIG. The control unit 10 sends a calling signal from a telephone equipped with a key operation unit 20 to the base station 200 through an uplink control channel to the base station 200. The billing information processed and generated by the billing system of the exchange control station 300 connected to the base station 200 is received via the downlink control channel from the base station 200, and is displayed on the charge display 40 via the charge display interface section 30. It was configured to display.

0004

The conventional charging system described above has a charging system on the side of the switching control station 300 that processes calling signals from each mobile device 100 to generate charging information. Since the configuration is such that billing information is notified to and displayed on the mobile device 100 through a downlink control channel, even a simple mobile radio system does not require the installation of such a billing control system on the switching control station side. The problem was that it was not suitable as a simple type. The purpose of the present invention is to
The object of the present invention is to realize an adapter that can be added to each mobile device of a simple mobile radio system and display usage charges on a public network.

[0005]

[Means for Solving the Problems] This purpose is to monitor up and down signals between the conventional control section 10 and the key operation section 20 of the telephone in each mobile device 100, with reference to the principle diagram of FIG. an adapter control section 1 that detects a calling signal from the key operation section 20 and creates a call control signal; and an area code monitoring section that monitors the area code of the telephone number of the called party based on the control signal. 2, and a charging information storage table 3 that stores charging information for each area code in advance, and the area code monitoring unit stores the charging information according to the area code of the telephone number of the calling destination of each mobile device. This is achieved by the simple mobile radio public adapter of the present invention, which is configured to select the corresponding portion of the memory table (3) and display the charge for the call on the display 40.

[0006]

[Operation] In the public adapter provided in each mobile device 100 of the present invention, the adapter control section 1 is different from the conventional control section 1.
0 and the key operating section 20 of the telephone set, detecting a calling signal from the key operating section 20, and creating a control signal. Then, the area code monitoring unit 2 controlled by the control signal from the control unit 1 monitors the area code of the telephone number of the call destination from the key operation unit 20 and restricts calls. Select and read out the information in the billing information storage table 3 that corresponds to the station number. Then, the integrated value of the call charge from the start of the call to the end of the call on the telephone of the mobile device 100 is known. In this way, the area code monitoring unit 2 and the billing information storage table 3 controlled by the control unit 1 know the cumulative value of charges from the start of the call to the end of the telephone call of each mobile device 100, and calculate the cumulative value. Since it is a method of displaying on the charge display 40, it is convenient to calculate and display usage charges similar to a public network at low cost.

Embodiment FIG. 2 is a block diagram showing the configuration of a simple mobile radio public adapter according to an embodiment of the present invention. 1 in the diagram
0 is a conventional control unit (Tu), 20 is a conventional key operation unit (
40 is a conventional fare display. The adapter control section 1 of the adapter of the present invention is a conventional control section (T
u) The area code monitoring unit 2 monitors the up and down signals between the phone 10 and the key operation unit (Cu) 20, and if the upstream signal is dial data from the key operation unit 20 of the telephone, the area code monitoring unit 2 detects the billing information. Read and compare the data in each ROM of the storage table 3, and extract the charging table that corresponds to the area code, or force the call termination code to be set by the control unit (
Tu) Send to 10. When a call is made, the call code is received from the control unit (Tu) side, and billing data is sent to the display 40 to display that billing is in progress. At this time, the audio is muted for, for example, 40 seconds from the start of the call, and the billing display is flashed. If the call ends or the call is not completed during this time, the billing display is turned off. Also, if you wish to make a normal call during this period, press the mute key on the key operation unit (Cu) once, the charge display will turn on, and the charge will be charged, and the charge will be added for a certain period of time. . Next, when a call termination operation is performed, a call termination code is sent from the control unit (Tu) side, and the addition is stopped using the code, the totalization process is performed, and the charge is displayed on the display 40. In this way, by simply adding the hardware of the simple configuration of the adapter shown in FIG. It will be possible to display usage charges based on the usage fee.

[0008]

[Effects of the Invention] As explained above, according to the present invention, usage charges can be displayed on a public network by adding an inexpensive and simple adapter to each mobile device. The effect of improving convenience for users of the wireless system can be obtained.
