Description

A broadband public telephone system and its implementation method

Technical field

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

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.

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 telecom The public telephone system used in the business center of the business hall or office building, for the manned public telephone system, its main functions are:

1. The call is initiated by the control terminal equipment to prevent unauthorized users from using the service;

2. After the user uses the terminal to output the call fee after the end of the call, the operator obtains income.

The present invention is aimed at the manned public telephone system, and proposes a new public telephone system and its realization method.

The implementation of the current broadband public telephone system is generally independent of the switching system, and only the terminal equipment is metered and controlled at the switching terminal. The following modes are generally adopted:

1. Use public telephone meter to provide service

Just configure the meter, connect the phone to the meter, and the meter will control the phone and display the call cost after the call ends. The implementation of this mode is relatively simple, but there are disadvantages such as low billing accuracy and easy to cause user disputes, especially in case of tariff adjustment, there is a huge workload of data configuration, and it also has a large workload of maintenance;

2. Use public call billing server

Add hardware equipment, transfer and integrate several subscriber lines, (or control on the loop relay,) control the terminal equipment by the server, and adopt the method of built-in billing server, so it may be included in the bill of the accounting center The output is different, and there is also the disadvantage of low billing accuracy;

3. Finished with a small exchange system

Connect the PBX device on the terminal phone that needs to be configured as a public phone, so that it can be connected to the switching network, control the phone terminal on the PBX device, and use the billing system of the PBX device to complete the tariff calculation. This is essentially the same as the second implementation method, but has the disadvantages of low billing accuracy and high investment cost.

Moreover, when an operator needs to set up multiple business locations, using the above existing systems requires a corresponding investment in multiple sets of software and hardware equipment, so the cost is relatively high and the maintenance workload is relatively large.

And these implementations generally have the following disadvantages:

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

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

3. The internal interface is not very open;

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

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;

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

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 difficulty in actual construction.

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. The switching device collects CDRs. Therefore, its implementation is based on attaching additional equipment to the switching terminal, or adding pricing equipment, or establishing another switching equipment so as to achieve the purpose of controlling the terminal phone and collecting bills.

With the evolution of the telecommunication network, broadband switching systems (such as soft switching systems) have been introduced to the market. This system is based on the IP protocol, and its system has good openness and scalability. provides the basis.

The present invention makes full use of the existing resources on the telecommunication network under the condition that the modern switching network (especially the soft switching network) is becoming more and more intelligent, making it easier for switching equipment and third-party equipment to exchange information and protect The operator's existing investment; adopt a flexible framework structure to realize the public telephone system.

Try to give a concrete example below, further illustrate technical scheme of the present invention:

In practical application, the broadband public telephone system mentioned in the present invention, its hardware part includes accounting center, switching equipment, public telephone server, public telephone operation terminal, telephone terminal equipment, wherein accounting center and switching equipment are operators In the existing system, the public phone server can choose a commercial server on the market according to the operation scale, and the public phone operation terminal can be an ordinary PC; the implementation method of the system can be completed by performing the following steps:

1. Designate several telephones as public telephone terminals on the switching device, and specify the address of the controlled public telephone server;

2. Configure the public phone server on the configuration terminal of the public phone server, and assign the controlled public phone terminal to the corresponding public phone operation terminal scope;

3. When a user uses a public phone terminal to make a call, he needs to go to the public phone operating terminal of the terminal to apply for service use;

4. The public telephone operation terminal accepts the user's application and reports the current credit status of the terminal to the server;

5. The user picks up the phone to initiate a call, and the switching device judges that it is a public phone service, and then initiates an authentication request to the designated public phone server;

6. The public phone server controls the authentication result according to the user's credit status. If the credit is not enough to initiate a call, it will notify the switching device and block the phone;

7. If the user has enough credit, judge the length of time (or byte flow) that the user can use the service;

8. When the user voluntarily terminates the service, or the user's service usage exhausts its credit limit, the switching device will voluntarily suspend the service. At this time, the business ends;

9. After the business is over, the public phone server asks for the call bill from the billing center or the designated billing server, and safely transfers it to the public phone operation terminal;

10. The operation terminal accepts bills and user settlements;

11. The operator can conduct business statistics on each operating terminal on the public phone server side, and determine the increase or decrease of equipment at each operating point.

The software part of the system is divided into two parts: user authentication and tariff settlement.

Wherein the user authentication step specifically also includes the following processing content: (in this process, the RADIUS protocol or other communication protocols can be used)

The user goes to the operation terminal to apply for the public phone service;

The administrator specifies the telephone terminal at the operating terminal, and enters the credit limit of the terminal;

The public telephone server accepts the input from the operation terminal, and specifies that the telephone terminal is in the open state;

The user initiates a call using the terminal;

The switching device performs credit authentication of the terminal to the public phone server;

If the authentication fails, the terminal phone will be placed in a locked state, and the user cannot use the service;

If the authentication is passed, the public phone server will transfer the credit line to the switching device;

The user starts to use the terminal to make calls;

If the user finishes using the service, or the credit limit is insufficient, the service ends, so far, the authentication and authorization step ends.

Tariff checkout part:

After the authorization and authentication service ends, the switching device instructs the public phone server to end the service;

The public telephone server transmits detailed call records to the accounting center (or an independent billing server);

The public phone server obtains the bill for the call from the accounting center (or an independent billing server);

The public phone server passes the bill to the designated public phone operation terminal;

The public telephone operation terminal outputs the call bill to the user, and the service of the entire public telephone system ends.

Obviously, this system requires the switching system to support a certain communication protocol, such as the RADIUS protocol, in order to realize the communication with the public phone server. For the switching devices that do not have this function on the Internet, the operator can connect these devices to the soft switching system, so that Gain the ability to support these communication protocols.
