Diameter credit control (DDC) protocol-based method and system for charging telecommunication service in real time

Abstract

The invention relates to a diameter credit control (DDC) protocol-based method and a DDC protocol-based system for charging a telecommunication service in real time. The method comprises the following steps that: 1, a network element node sends a charging message to an intelligent routing agent node; 2, the intelligent routing agent node receives the charging message, converts the format of the charging message and forwards the charging message to a target online charging system (OCS) node of the charging message; 3, the OCS node receives the charging message, performs operation and returns acontrol message to the intelligent routing agent node; 4, the intelligent routing agent node receives the control message, converts the format of the control message and forwards the control message to a target network element node of the control message; and 5, after receiving the control message, the network element node performs operation according to the control message. An OCS system can be introduced into a network, and the reformation of the network element node in the network is avoided simultaneously.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and a system for real-time charging of telecommunication services based on the DCC protocol. Background technique [0002] Online charging system (OCS, ONLINE CHARGING SYSTEM) refers to a charging system that participates in communication process control, which can solve problems such as real-time credit control of users, prepaid data services and real-time charging of value-added services. The OCS system adopts the DCC (Diameter Credit Control) protocol of the 3GPP standard. [0003] The online billing system can effectively reduce the risk of user arrears, improve user perception, and at the same time provide an ideal billing method for the growing data services. 3GPP (3rd Generation Partnership Project, 3rd Generation Mobile Communication Standardization Partnership Project) proposes an OCS system architecture. [0004] In the technical architecture of 3GPP, the CAP (C...

Problems solved by technology

[0004] In the technical architecture of 3GPP, the CAP (CAMEL Application Part, CAMEL Application Part) protocol is used for communication between the Short Message Center (SMC) and the OCS system, while in the existing telecommunication network, the SMC uses the SMPP+ protocol, so if According to the OCS architecture of 3GPP, it will inevitably involve the transformation of the SMC of the entire network, which will have a great impact on the operation of the SMC of the existing network.

[0005] With the development of users, the OCS system is facing capacity expansion. In the existing network, the OCS system cannot achieve large-capacity smooth expansion.
