Method for selecting charging system in next-generation network

Abstract

The invention discloses a method for choosing a charging system in an NGN. In a push mode charging process, the method comprises the steps that after a request message for the resource initialization of service sent by a SCF is received, a PD-FE carries out strategy decision-making and authorization to QoS resource requested by the service and interacts with a TRC-FE to carry out validity check to the QoS resource requested by the service; according to the result of the strategy decision-making and the authorization and the result of the validity check of the resource, the PD-FE carries out final acceptance decision-making; if the final result of the acceptance decision-making is to accept the resource request, the PD-FE chooses a charging system for the service, and the address of the chosen charging system is sent to the PE-FE that is then informed to use the charging system corresponding to the address to carry out charging operation; or the PD-FE informs the PE-FE to use the charging system allocated statically to carry out the charging operation. By adopting the method of the invention, the choosing efficiency of the charging system of the NGN network and the usability of the charging system can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for selecting a billing system in the next generation network. Background technique [0002] Conceptually speaking, NGN (Next Generation Network) is based on packet transmission, which can provide voice, data and multimedia integrated services, can guarantee service quality and security, and can integrate various access methods to facilitate third parties. Provide an ideal communication network for applications. At present, many international and regional standardization organizations are conducting research on NGN, and operators in many countries are also actively deploying NGN. However, the research on NGN and the deployment of the network are still in a stage where they can only provide some services and some capabilities. With the deepening of research and the improvement and enhancement of equipment capabilities, the NGN built in the future will be able to provide more s...

Problems solved by technology

[0016] The method of statically configuring a single billing system on the billing client is sufficient for a network with a single billing system, but if multiple billing systems are configured in a network, this method lacks flexibility

For example, when a billing system fails or the load is too heavy, it is necessary to manually reconfigure the billing system address on the PE-FE, and the billing information may be lost during the manual configuration process.
