Online charging service processing method, gateway and system

Abstract

The invention relates to an online charging service processing method, a gateway and a system. The method comprises the following steps of: sending a first CCR-U (Credit Control Request-Update) message triggered by a new service of a user to a charging server by a charging gateway; receiving a first CCA-U (Credit Control Answer-Update) message sent by the charging server; carrying out credit control according to a maximum available quota carried by the first CCR-U message and an allowable minimum quota unit; and when the maximum available quota is needed to be reported, sending a second CCR-U message to the charging server, and carrying out credit control according to the second CCR-U message by the charging server. When the minimum quota unit is needed to be reported, waiting for the CCA-U message sent by the charging server is not needed, in addition, the charging server does not need to send the CCA-U message to the charging gateway, and thus, the problem that the real-time property of the system is lowered due to too much message interaction between the charging gateway and the charging server in the traditional charging system is solved, and the condition that the charging system is out of work due to too many CCR / CCA messages is avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to a packet domain online charging service processing method, gateway and system. Background technique [0002] At present, with the development of the online charging system, the performance of the online charging system has become the focus of attention of operators. The main performance indicators of the online billing system include real-time performance, reliability, scalability and fault tolerance. Among them, real-time performance is a very important indicator, and the operator has clear regulations on the average delay of system processing. Therefore, how to improve the processing speed of the system and reduce the response delay of the system is the key technology of the online billing system. [0003] An existing online charging system mainly includes functional entities including a user terminal, a charging gateway and an online charging server. Among them, the function of the...

[0005] However, in the existing online billing system, when the business is running normally, the CCR / CCA messages must appear in pairs. If there are a large number of users, the number of message interactions will increase exponentially, which consumes too much resources and affects the processing speed of the system.

For example: if the amount issued by the online billing system is small, the billing gateway needs to interact frequently with the online billing system, which affects the processing speed of the system; or the online billing system is abnormal, and the billing gateway If the CCA message is not received within the time limit, the message will be retransmitted, which will affect the processing speed of the system. If the above situation occurs to a large number of users, the billing system will even be paralyzed due to excessive CCR / CCA
