Problems solved by technology

The main problems are: the bills of calls made by users cannot be counted in time
This type of phone cannot communicate with the management platform in real time
Now the password accounting service (such as 200 service) has also been carried out, but it is only limited to the long-distance service and is not suitable for the requirements of the public telephone system

Embodiment Construction

[0016] 1. System structure

[0017] figure 1 It is a structural diagram of an intelligent public telephone system. The whole system is composed of smart IC card terminal equipment 1 and a central processing platform 2 . The smart IC card terminal equipment can establish a connection with the central processing platform through the switching equipment of the telephone network. The central processing platform can handle the user's call business, and can also detect the status and related information of the smart IC card terminal equipment. The central processing platform provides statistics and management information for the system management center.

[0018] 2. Communication timing

[0019] figure 2 is the communication sequence diagram. The smart terminal device mainly communicates with the media gateway of the processing platform. The communication method includes communication timing and communication information. Firstly, the terminal device is connected to the pro...

Abstract

An intelligent communication method for public telephone system includes such steps as connexting terminal device to processing platform via switch, the platform generating and sending a challenge word to the terminal device, the terminal device transmitting account number, IC card number and cipher to the platform, the platform authenticating the IC card number or account number and sending the tariff to the terminal device, offhook, the platform sending charge start command to terminal device and beginning accounting fee, and normal talking while the terminal device sending state information to the platform until talking stops, or when talking abnormally, the platform stopping the talking.

Description

technical field [0001] The invention relates to a communication method, in particular to a communication method between a terminal device and a processing platform in an intelligent public telephone system. Background technique [0002] Unattended public telephones are mainly composed of magnetic card telephones, IC telephones and coin-operated telephones at present. Their common feature is that the terminal completes the billing function for the user's call. The generated bills are stored in the terminal. The main problems are: the bills of calls made by users cannot be counted in time. The system cannot reflect the problems existing in the terminal and the call process in a timely manner, and the statistical data lacks real-time performance. No network management function, poor security. [0003] In recent years, people have paid more and more attention to the development of IC card phones. China Telecom issued stored-value IC cards. The IC card should be used on a d...
