Device, system and method for realizing communication charging in communication network

Abstract

The invention provides a device, a system and a method for realizing communication charging in a communication network, a charging device is arranged between an OCS and an SCP, the charging device interacts with the SCP through a TCP, and the charging device interacts with the OCS through a TCP / SCTP. The charging device receives a core network signaling related to a call service from the SCP, packages the core network signaling into a request message based on a diameter protocol, and sends the request message to the OCS; in a communication call service process, according to a core network signaling or a response message based on a diameter protocol, the charging processing capability of the OCS is analyzed, whether flow control needs to be carried out on the OCS is determined, if yes, the flow control is carried out on the OCS so that the core network signaling which is subsequently sent by the SCP and relates to the call service is not forwarded to the OCS, and if not, the flow control is carried out on the OCS so that the core network signaling which is subsequently sent by the SCP and relates to the call service is not forwarded to the OCS. And the analysis process of the OCS charging processing capability is continued. In this way, continuous interaction between the OCS and the SCP in the communication call service process is guaranteed, and real-time charging is achieved.

Description

technical field [0001] The invention relates to communication technology, in particular to a device, system and method for realizing communication charging in a communication network. Background technique [0002] Currently, communication operators provide terminals with various communication services through communication networks. figure 1 A schematic diagram of an architecture of a communication network providing a communication service for a client provided in the prior art. As shown in the figure, the mobile communication network, the public switched telephone network (PSTN) and the intelligent network, etc. communicate and interact through a service switching point (SSP), and the SSP implements the communication connection function. The Mobile Switching Center System / Location Visitor Register (MSCS / VLR) of the mobile communication network can be integrated in the SSP to realize terminal positioning and communication call services in the mobile communication network. ...

AI Technical Summary

Problems solved by technology

During the communication and call service process of the terminal, the ability of the OCS to perform billing based on the core network signaling received from the SCP will affect the duration of the communication call service of the terminal, thereby affecting the user experience of the terminal

When the OCS is in the communication call service process of the terminal, due to its limited capacity, or too many core network signaling received from the SCP per unit time, it cannot process the core network signaling received from the SCP in time and perform billing, which will lead to Unable to bill in time for the communication call service of the terminal, or abnormal interruption of the communication call service
