Method for charging communication and charging trigger network element

Abstract

The invention discloses a method for charging communication and a charging trigger network element. The method comprises the following steps that: when the position updating of a user is detected, the charging trigger network element judges whether the granularity of the position updating accords with a preset granularity of selective flow unloading; and the charging trigger network element triggers a charging system to keep executing a charging flow or triggers the charging system to stop the charging process according to a judgment result. By the method for charging communication, the interactive flow between the charging trigger network element and the charging system is reduced, so redundant charging data is avoided, and the processing performance of the charging trigger network element and the charging system is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication charging method and a charging trigger network element. Background technique [0002] In a communication system, a network data packet is usually routed and forwarded to a user equipment through a packet data network gateway (Packet Data network Gateway, P-GW), a service gateway (Service Gateway, S-GW) and a base station. When the user performs location update, for example, when cell switching or tracking area switching occurs, a communication charging method based on the user location needs to be implemented. [0003] A communication charging method based on user location in the prior art mainly includes: [0004] The packet data network gateway or GPRS gateway support node (GPRS Gateway Supporting Node, GGSN) detects the user location update event, and the PGW / GGSN triggers the charging system to continue the charging process according to the abov...

Problems solved by technology

[0005] In the process of researching the existing technology, the inventor found that if the update of the user's location leads to the disconnection of the user's bearer layer connection, the user's location update event and the bearer layer connection disconnection event will be detected on the charging trigger network element, and the calculated The fee-triggered network element needs to interact with the billing system twice, and the above-mentioned location update process does not generate new billing data. The existing communication billing method produces more redundant steps, which reduces the cost of the billing system. processing performance
