Description

Method for Realizing International Debit Card Business

technical field

The invention relates to a method for providing services to network terminals in the field of telecommunication, more specifically, to a method for realizing international account card services.

Background technique

Charge card service is one of the 25 services suggested by the International Telecommunications Union (ITU) in the Intelligent Network Capability Group (CS-1). Its main feature is to allow business users to make calls on any telephone set (such as a dual-tone multi-frequency DTMF telephone set), and charge the fee to a specified account number. Business users who use debit card business must have a unique personal card number (Card Number). When using this service, the service user shall enter the access code, card number, and password (Personal Identification Number, PIN for short) according to the regulations. When the network confirms the input card number and password and sends a confirmation instruction to the business user, the business user holding the card can dial the called number to make a call as in a normal call.

For the business characteristics and dialing process of the debit card business, you can refer to the "Intelligent Network Standard" compiled by the China Ministry of Posts and Telecommunications Transmission, China's "FPH, ACC, VPN Numbering and Dialing Procedures" drafted by the China Ministry of Posts and Telecommunications Research Institute of Telecommunication Transmission, "FPH , ACC, Meaning and Process of VPN Service", "Technical Specifications for Smart Network Account Card Call Service (No. 300)" issued by the Ministry of Information Industry of China on February 23, 1999, "Called Call Service, Account Card Call Service and Supplementary Provisions on the Business Meaning and Process of Virtual Private Network Services and Numbering and Dialing Procedures, etc.

With China's opening up to the outside world, people's living standards are improving day by day, more and more people travel abroad, more and more people go abroad for vacation and study, and more and more people start companies and do business abroad. When the user is abroad, calling domestic users, expensive international phone charges, language barriers, and cumbersome currency exchange make it very inconvenient for the majority of overseas personnel to communicate with others. There is an urgent need for an international debit card service, that is, when the user is traveling abroad, on vacation or doing business, he can still enjoy his domestic debit card service, and the call flow is exactly the same as the domestic call. The above situation also exists for telecommunications users in other countries.

The above-mentioned "Intelligent Network Billing Card Calling Service (No. 300) Technical Specifications" and "Supplementary Provisions on Called Centralized Payment Service, Billing Card Calling Service and Virtual Private Network Service Business Meaning and Process, Numbering and Dialing Procedures" In the international incoming call service, the routing code transmitted from abroad to my country's international service switching point SSP is: "KP1+LD+1120CCCC", where KP1 represents the terminal type, LD is used as a language bit in manual connection, and is used as a language bit in automatic connection "0", CCCC is the country code of the other party, with a fixed length of 4 digits, including: country code, 1-3 digits; company code, 1-3 digits. If the country code plus company code is less than 4 digits, "0" will be added at the end. For the international SSP, since it cannot receive the calling number, the international SSP needs to know that the service is a 300 service according to 1120, put the service key of the 300 service into the service key of the IDP, and send the routing code as the called number to SCP, the SCP judges according to 1120 that it is the 300 service of an international incoming call, and then puts the above CCCC into the calling number. According to its regulations on international incoming calls, when it is used for international debit card business, it has the following disadvantages: it is necessary to have an international SSP, which is obviously necessary for the service providers of various provincial networks and local networks. Impossible; it is stipulated that the service control point SCP puts CCCC into the calling number as the billing number, which is impossible for the billing system to meet the needs of calling different places in China from different places in the United States with different rates. ; The international SSP needs to know that this service is the intelligent network service of the 300 billing card according to the routing code 1120, put the service key of the 300 intelligent network service into the service key of the IDP (Initial Detection Point, that is, the initial detection point), and route The code is sent to the SCP as the called number, which greatly changes the existing network SSP. If other types of intelligent network services are to be added, it is obviously impossible to re-modify the SSP software.
