为了在基于GTP接口协议的电信系统中实现在数据流量业务的在线计费,这里针对现有的电信系统核心网和计费系统架构,提出一种新的技术实现方案。首先对总体方案进行了介绍,然后对基于GTP协议的系统在实现流量业务在线计费时的难点及该方案对应的解决方法细节进行了重点描述。方案既具备流量业务的在线计费能力,又保留了原有的离线计费能力,在具体生产系统应用中具有很强的适用性。
In order to realize the online charging of the data traffic service in the telecommunication system based on the GTP interface protocol, a new technical implementation solution is proposed for the existing telecom system core network and charging system architecture. Firstly, the overall scheme is introduced, and then the difficulties when the system based on GTP protocol is used to charge the online charging of traffic service and the solution details of the scheme are described emphatically. The scheme not only has the online charging ability of traffic service, but also retains the original off-line charging ability and has strong applicability in the application of specific production system.
