Embodiment
Below in conjunction with accompanying drawing, will be described in more detail each preferred embodiment of the present invention.
Overload control in the mobile communication test of the present invention in the method for overload control test, its whole flow process can be divided into two parts: 1, Guo Zai generation; 2, the control after overload produces.For this reason, the present invention also is divided into two independent parts with overload measurement: the test of control after producing at the test of overload generation with at overload, if overload production process and overload control section have all passed through test, so whole overload control test is just passed through, and produces at overload and can adopt the big talk tool of working to simulate the professional overload that triggers of big capacity and produce; Can come overload control to carry out DCO detailed checkout by directly sending overload message at the test of overload control, in fact not produce real overload, and be virtual overload to the overload control module.
The overload control test macro of realizing according to inventive concept comprises following module: 1, UI (User Interface user interface) Subscriber Interface Module SIM: offer the input that the tester controls overload control test, and come the output overloading type according to user's input, overload class should adopt which kind of overload control algolithm etc.; 2, control module: according to tester's input, formation overload control test input is controlled the overload measurement flow process, and is judged the overload type according to tester's input, and overload class should adopt which kind of overload control algolithm etc.; 3, network communication module: realize the communication of overload control testing software and base control.
The method of overload control test specifically comprises two big steps in the mobile communication test of the present invention:
At first, the tester simulates big capacity business by the big talk tool of working, and when telephone traffic reaches overload generation condition, whether contains overload messages according to alarm module in the base control or signaling tracing and judges overload production process correctness;
Secondly, by overload measurement software the overload control module is carried out DCO detailed checkout:
1, on PC, installs overload measurement software, and PC and base control are in the consolidated network environment;
2, start the overload Control Software;
3, import related data at the inputting interface of overload measurement software users interface module;
