[0006] At present, after the communication equipment is connected to the network, when the network speed is unstable or the communication is interrupted, most of the alarms will be issued to the network. After the network is repaired, the communication equipment will continue to be connected, and the communication equipment will restart data transmission, which will lead to abnormalities in the network. When the data transmission of the communication equipment stagnates or the efficiency decreases, this application aims to automatically activate the backup network in the area during the communication interruption of the communication equipment, screen all the backup networks, and make the communication equipment choose the best connection

Embodiment 1
[0069] Embodiment 1: Limited conditions, the communication equipment data transmission rate collection and analysis sub-module collects the multi-segment data transmission rate of the communication equipment in the previous network, and sets the multi-segment data as L 1 , L 2 , L 3 , where the above data L 1 The real-time transmission rates are 12M / s, 7M / s, 14M / s, 11M / s, data L 2 The real-time transmission rates are 6M / s, 7M / s, 11M / s, 9M / s, data L 3 The real-time transmission rates are 8M / s, 15M / s, 11M / s, and 13M / s respectively. Extract the minimum values of the real-time transmission rates of the above multi-segment data 7M / s, 6M / s, and 8M / s, and extract the above-mentioned multi-segment data real-time transmission The maximum speed rate is 14M / s, 11M / s, and 15M / s. Set the multi-segment data transmission rate range of the current communication device in the previous network to K0min~K0max, according to the formula:

Embodiment 2
[0073] Example 2: Limiting conditions, set between the specified time T0 ~ T1, set different networks as b1, b2, b3, and the number of times that different networks report errors as 3, 2, 4, among which, set the number of times in the network b1 The failure degree of the first error report is set to 30%, 17%, 37%, the failure degree of several error reports inside the network b2 is set to 40%, 51%, and the failure degree setting of several times of error reports inside the network b3 is set For 42%, 31%, 56%, and 64%, set the failure rate of a single network to set R0, according to the formula:
[0074]
[0075]
[0076]
[0077] Set the comprehensive failure rate R of all error-reporting networks in the area, according to the formula:
[0078]
[0079] Calculate the failure rate of the current single network and the comprehensive failure rate of all error-reporting networks in the area. The threshold is set to 40%. If the rate is greater than the set threshold, m...

Abstract
The invention discloses a system and method for network switching when network communication is interrupted. The system includes a network communication state detection module, a communication device demand command receiving module, a communication device network speed demand analysis module, a backup network authorization priority selection module and a communication device. Interruption fault real-time upload module, network communication status detection module is used to monitor the network status between different communication devices, communication device demand command receiving module is used to receive communication device commands, communication device network speed demand analysis module is used to communicate The network speed of the device is used for statistics and analysis. The backup network authorization priority selection module is used to apply for access to the communication device to authorize the communication device. In the process of device communication interruption, the backup network in the area is automatically activated, and all backup networks are screened, so that the communication device can choose the best connection.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a system and method for network switching when network communication is interrupted. Background technique [0002] Network interruption means that when the CPU is running the program normally, due to internal, external events or events pre-arranged by the program, the CPU interrupts the running program and switches to the service for internal / external events or pre-arranged events. Go in the program, the service is completed, and then return to execute the program that is temporarily interrupted. [0003] Network fault diagnosis should achieve three purposes: determine the fault point of the network and restore the normal operation of the network; find out the unsatisfactory aspects of network planning and configuration, improve and optimize the performance of the network; observe the operating status of the network and predict network communication in time quality. Network...
