System and method for simulating transceiver signaling based on online charging environment

Abstract

The invention relates to a system and method for simulating transceiver signaling based on an online charging environment. The system comprises a signaling separation module, a signaling storage module, a signaling dispatching module and a signaling receiving and sending module. A data file is restored through the signaling separation module to obtain a data packet collected by the system, the data packet is analyzed to obtain signaling data, the signaling data are sent to the signaling storage module one by one, a control instruction sent by the system is processed through the signaling dispatching module, a session instruction is sent to the signaling receiving and sending module, request signaling is searched for and extracted from the signaling storage module through the signaling receiving and sending module and is sent to a target specified by the system, response signaling returned by the target is received and analyzed, and corresponding response movement is carried out. According to the system and method for simulating the transceiver signaling based on the online charging environment, only a small part of attributes irrelevant to the system is modified, simulation validity is improved, test time is shortened, test efficiency is improved, test cost is lowered, and the wide application range is achieved.

Description

technical field [0001] The present invention relates to the field of online billing systems, in particular to the field of R&D and testing of the online billing system, and specifically refers to a system and method for simulating sending and receiving equipment signaling based on the online billing environment. Background technique [0002] The Online Charging System (OCS) based on the Diameter (Diameter) protocol is a real-time interactive charging system based on service usage and the system. Relying on this system, it can solve user real-time credit control and prepaid usage data services. and real-time billing of value-added services. Corresponding to this is the offline billing system, which collects bill information in the form of files after the session is completed. The billing will not affect the service process in real time, but the billing process is quasi-real-time. In the research and development process of the billing system, functional testing, regression te...

Problems solved by technology

In the process of mobile users using traffic, the generation and transmission of signaling will go through many network element devices, such as switches, mobile switching center (MSC), gateway GPRS (General Packet Radio Service) support node (GGSN), etc., each Level network element equipment may modify and supplement the content of signaling, and network element equipment (such as GGSN) that directly interacts with the billing system cannot simulate the signaling data generated and supplemented by back-end equipment (such as switches, MSCs) , which has caused a lot of inconvenience to the multiple testing links of the online billing system

[0004] In the testing process of the existing online billing system based on the Diameter protocol, a simulation program is used to simulate the signaling generated by the network element equipment. However, due to the complex network of telecom operators, including many There are differences in implementation. At the same time, users' online behaviors and user balance package status are different. The simulation program restores Diameter signaling with low authenticity. The online billing protocol has poor interactivity during the test process, and it is difficult to cover many real business scenarios.

Based on the above situation, on the one hand, the function test points and business branches of the online billing system under test cannot be completely covered; on the other hand, it is difficult to establish a test baseline, and regression testing is difficult
