Offline charging method and device

Abstract

The invention provides an offline charging method and device. The offline charging method comprises the following steps that after a service data bearer is established, when a user plane subsystem (UPPS) receives a service data starting instruction message triggered by a charging trigger functional (CTF) entity, local absolute time is acquired to obtain the opening time of a first generated call ticket, and the opening time is sent to a charging data functional (CDF) entity; when a time threshold value is reached or a flow threshold value is reached or the service data bearer is updated or the service data bearer is deleted, the UPPS acquires a local absolute moment as a current moment and transmits the current moment to the CDF entity; the CDF entity conducts call ticket calculation on service data according to the received message. The embodiment of the invention further provides an offline charging device on the other hand. According to the technical scheme, the filling-in of call ticket time information better conforms to actual service transmission time, and the problem that the time is inconsistent with actual duration as a result of the generated call ticket is avoided. Besides, time delay in message processing can be effectively shortened, and call ticket duration deviation is reduced.

Description

technical field [0001] The present invention relates to the technical field of packet data communication, in particular, the present invention relates to a method and equipment for offline charging. Background technique [0002] EPS (Evolved Packet Core, evolved packet core network) charging methods include online charging and offline charging. For the offline charging system, after SGW / PGW (Serving GateWay / Packet Data Network Gateway, serving gateway / packet data network gateway) collects the charging information, it passes CDF (Charging Data Function, charging data functional entity) and CGF (Charging Gateway Function, billing gateway function), sent to BD (Billing Domain, billing domain). In the offline charging system architecture, CTF (Charging Trigger Function) generates charging events, provides charging information, assembles charging information into charging events, and sends these charging events to CDF. However, the function of the CTF is still reserved in the n...

Problems solved by technology

[0008] In actual test scenarios, deviations or incorrect bill time information caused by the above situations often occur, and eventually CDF sends these wrong original bills to CGF. After CGF receives them, because there is no billing configuration rule, if the Billing threshold, billing maximum number of conditions and other billing configuration information, so bills are not checked and merged directly, and then checked after merging. After checking, wrong problem bills will be directly eliminated, which will result in some original bills Data loss directly affects the operator's billing results, leading to inaccurate or even wrong traffic bills generated by the billing center, which affects the accuracy and rationality of the billing data, and also brings certain losses to the operator

[0009] Therefore, it is necessary to propose an effective technical solution to solve the problem of inaccurate bill time information during offline billing
