JPS60226268A - Charging system of car telephone exchange - Google Patents

Abstract

PURPOSE:To eliminate the need for processing in which charging information is transmitted and received by using a data circuit between car telephone exchanges by storing charging information on calling in another area in the memory of mobile equipment, CONSTITUTION:When a subscriber A in an area A telephones to a subscriber B in another area, the charging information on the calling is recorded temporarily by a car telephone exchange 2 and sent out to the mobile equipment of the subscriber A after the calling end and stored in the nonvolatile memory in the mobile equipment of the subscriber A. Then, when the subscriber A returns to the area A, the mobile equipment sends position registration information to a car telephone exchange 5 in its area to register the position and also sends out the charging information stored in the memory to the car telephone exchange 5, which processes the information similarly to normal charging processing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mobile telephone subscriber's mouth, and more particularly to a billing system.

Description of the Prior Art Conventionally, when a mobile device makes a call in another area, its billing information is transferred from the other area's car telephone exchange to the white area's car telephone exchange using an inter-exchange data line.

The conventional charging method is shown below with reference to FIG. The circled area in Figure 1 is the service range.

For example, when a car phone subscriber A in a white area makes a call to a regular phone subscriber B in another area, the processing of the billing information is carried out because the car phone exchange 2 in the other area does not manage subscriber data for the subscriber. Therefore, it is impossible. Therefore, data is transferred from the mobile telephone exchange 2 in the other area to the mobile telephone exchange 5 in the white area using the interoffice data line 6. Therefore, there was a drawback that the replacement operation was complicated.

OBJECTS OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks inherent in the conventional technology.Therefore, an object of the present invention is to store billing information for calls made in other areas in a non-volatile memory of a mobile device,
To provide a new billing method for a car telephone exchange that does not require transfer of billing information between exchanges by causing the car telephone exchange in the white area to report the stored information when the mobile device enters the white area. There is a particular thing.

Structure of the Invention In order to achieve the above-mentioned object, the billing method of the mobile telephone exchange according to the present invention is such that a mobile telephone exchange is specified by a plurality of mobile control exchanges, or all mobile subscribers (mobile devices) are connected to a self-registered exchange. In a mobile telephone switching system in which telephone switching services can be received even in areas other than the controlled area, and all calls are charged at the subscriber's registered switching center, charges are sent from the switching center to the mobile device. A memory for storing information and a power holding time limit circuit are provided to create time to hold the wireless communication channel after the end of a call in order to store billing information. A function that sends billing information to a mobile device when providing a connection service to the mobile device, and a function that sends billing information to the mobile device that is stored in the mobile device when a location registration request is received from the mobile device that is registered with the switching center. It is configured with a function of collecting information and charging for calls made in other areas.

3. Detailed Description of the Invention Next, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention;
The figure is a block diagram showing one embodiment of the internal circuit of a mobile device. In Figure 2, car phone subscriber A in the white area
When communicating with subscriber B in another area, the subscriber B is connected to subscriber B through the wireless base station 1 in the other area, the car telephone exchange 2, and the general telephone exchange 3.

In FIG. 3, reference numeral 11 is an antenna, 12 is a transmitter/receiver, 13 is a control circuit, 14 is a memory such as a non-volatile memory for storing billing information, and 15 is a wireless call after a call is completed to store billing information. A power supply holding limit circuit (delay time circuit) constituted by a timer and the like to form a time for holding a channel, 16 a battery, and 17 a handset.

Therefore, the billing information for the call between subscribers A and B is recorded in the carrier mobile telephone exchange 2 and sent to the subscriber's mobile station at the end of the call. The mobile device of subscriber A has a dedicated non-volatile memory 14 for storing the billing information, and the billing information received through the antenna 11 and transceiver 12 is written into this memory 14 by the control circuit 13. At this time, the 1-power supply hold time limit circuit 15 functions to hold the wireless communication channel for a certain period of time even after the handset 17 is on-hook and the call is ended, in order to store billing information in the memory 14.

Thereafter, when subscriber A returns to the white area, the mobile device sends location registration information to the mobile telephone exchange 5 in the white area to perform location registration. When the mobile telephone exchange 5 receives the location registration information, it requests the mobile station to send billing information, and the mobile station reads the billing information written in the memory 14 and sends it to the mobile telephone exchange 5 in the white area. Send. The car telephone exchange 5 processes this information in the same way as normal billing processing.

Effects of the Invention As explained above, the present invention stores billing information for calls made in other areas in the memory of a mobile device, and when the mobile device returns to a white area, transfers the billing information to the car telephone exchange in the white area. Reporting has the effect of eliminating complicated processing when transmitting and receiving billing information using data lines between mobile telephone exchanges.
