Example Embodiment

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and implementation examples.

[0032] like figure 1 As shown, a method for realizing the automatic detection and automatic switching of the dual network ports of the dispatching terminal comprises the following steps:

[0033] (1) After the dispatching terminal system starts up normally, four global variables are created in its memory; the four global variables are network port 1 enable state value network_port_first, network port 2 enable state value network_port_second, network card actual Status value network_port_value and automatic switching flag g_network_port_auto_switch;

[0034] (2) The scheduling terminal system is initialized, the status of network port 1 and network port 2 is set to disabled, and the status value is set to 0, and the status of network port 1 and network port 2 is reported to the client to ensure that the network port The consistency of the...

Abstract

The invention provides a method for realizing automatic detection and switching of double network ports of a scheduling terminal. The method comprises the following steps: creating four global variables, namely a network port 1 enabling state value, a network port 2 enabling state value, a network card actual state value and an automatic switching flag bit; when automatic switching is carried out,setting the flag bit of automatic switching to be 1, judging the working state of the network port by reading the actual state value of the network card, and when manual switching is carried out, theflag bit of automatic switching is set to be 0, starting manual switching of the network port. According to the method, if the main network port goes wrong can be efficiently and quickly detected, the main network port can be switched to the standby network port in time, and the registration process initiated by the scheduling terminal to the soft switch is completed, so that the basic call and service functions of the scheduling terminal are better realized, and the stability and reliability of a scheduling terminal system are improved.

Description

technical field [0001] The invention belongs to the technical field of next-generation network communication, and particularly refers to a method for realizing automatic detection and switching of dual network ports of a scheduling terminal, wherein the switching includes manual switching and automatic switching functions. Background technique [0002] Dispatching communication equipment is a communication equipment that provides production scheduling or command and control for internal or group users. The dispatching terminal can realize a series of voice communication functions such as incoming calls, outgoing calls, group calls, conferences, forced insertion, and forced removal. The dispatching system is widely used in professional dispatching and communication fields such as electric power, coal, petroleum, military, rail transit, and government emergency. [0003] Due to the rapid development of IP networks, dispatching services based on softswitch technology are more ...
