Embodiment Construction

[0036] In order to understand the present invention more clearly, describe the present invention in detail in conjunction with accompanying drawing and embodiment:

[0037] Such as Figure 1 to Figure 5 As shown, in order to simulate the one-to-many relationship between MSC and BSC in the real environment, the present invention needs to adopt the mode of networking of multiple PCs to connect with MSC, through figure 1 and figure 2 It can be seen from the comparison that the PC simulation software includes the registration function of the channel machine and the simulation of the BSC.

[0038] For each PC, we need to do the following preparations:

[0039] c) To set the IP address, multiple PCs can be connected to the same LAN through a router. Considering the network delay in the real environment, some PCs can be connected to the external network.

[0040] d) Set the parameters of each channel machine in the software of the present invention, such as setting color codes to...

Abstract

The invention relates to a switching center simulation test system based on a PC platform. The system is composed of a heartbeat sending module, a human-computer interaction module, a base station information reporting module, and a signaling receiving and processing module; the main responsibility of the heartbeat sending module is to communicate with the MSC After the socket network connection is established, ensure that the network connection between the BSC and the MSC is normal; the human-computer interaction module is mainly responsible for receiving the signaling information input by the user, and also responds to the signaling that the signaling receiving and processing module needs to send back, and sends it to the MSC through the socket , processed by MSC; use the button control in the MFC framework to split the signaling interaction process that could not be broken in BSC-MSC, so as to achieve the purpose of single-step sending debugging, and use the text control to modify some parameters in the signaling Manual settings are made to achieve ideal conditions for testing in extreme environments.

Description

technical field [0001] The present invention relates to signaling interaction and data acquisition equipment between a PDT base station (BSC (Base Station Controller)) and a switching center (MSC), in particular to a PC platform-based switching center simulation test system and method for providing multiple BSC--Simulation test environment for single-step debugging of single MSC. technical background [0002] Both BSC and MSC in the real environment are developed based on the c program of the shell command line of the linux system platform. The most commonly used program debugging method under Linux is GDB (GNU Debugger). GDB is a program debugging tool based on the shell command line. All debugging operations for programs include setting breakpoints, single-step running, and jumping into sub-functions. Execution is based on the operation of shell commands, and the way to view the source code is simply to print out a piece of code on the shell. Compared with the debugging t...
