Broadband public telephone system and its realizing method

Abstract

The system includes a switching device, a public phone server, a accounting center, public phone operation and telephone terminal. Under data control of the public phone operation center, telephone terminals connected to switching device are communicated to the public phone server. The method authenticates call initiated by user and settles accounts of user. The wideband public phone system provides features of opening, expandability, intelligent, easy of maintenance, good ratio between cost and performances, reliability and security etc.

Description

technical field [0001] The invention relates to a telecommunication network operating system, in particular to a manned broadband public telephone system in the system and a realization method thereof. Background technique [0002] In the modern telecommunications fixed-line operation business, the public telephone (hereinafter referred to as public telephone) system is an important means for operators to obtain profits. Especially with the widespread use of IP telephony, broadband public phone operation has become an important profit growth point for operators. By providing this immediate payment public phone service, it can provide convenience for the majority of users. [0003] The public telephone system in the prior art can be roughly divided into two modes: unattended and manned. For the unattended public telephone system, the common ones are magnetic card and IC card telephones; while the manned public telephone system is commonly used for tele...

Problems solved by technology

[0016] 1. Low intelligence, unable to carry out centralized management efficiently;

[0017] 2. When the tariff policy changes, the workload of data modification is huge;

[0018] 3. The internal interface is not very open;

[0019] 4. Due to the low configuration of equipment for calculating telephone charges, accurate billing cannot be obtained;

[0020] 5. When the operation scale is expanded, multiple sets of equipment need to be invested, the investment cost is high, and the maintenance workload is heavy;

[0021] 6. System operation is restricted by region. A system is generally concentrated in one region of a city and cannot be operated across regions.

[0022] After searching, "Shenzhen Guanri High-Tech Development Co., Ltd." applied for the patent of "the composition of the public telephone network and its realization method". Connecting to the operating telecommunication network, its ideological content is similar to the above third implementation method. This invention needs to establish an independent public telephone switching network, which cannot make full use of the existing equipment on the network. At the same time, it needs to establish an independent billing module, which cannot Obtaining billing information from the existing accounting center has the disadvantages of large investment and difficult actual construction

[0023] The implementation of the above-mentioned existing public telephone systems is based on the switching system of operation, which is relatively closed, and does not have open communication capabilities with third-party equipment, so the third-party equipment cannot control the action of the switching equipment, and it is not convenient to directly communicate with the third-party equipment.
