Problems solved by technology

However, in many abnormal scenarios, the AG35 module may fail to initialize the SIM card, the module is in flight mode, the network registration fails, the module is always in 2G mode, APN (AccessPoint Name, access point) dialing fails, and the call falls back to 2G However, after hanging up the phone, I cannot quickly return to 4G, APN dialing is successful but the network connection is not available, etc. A series of problems
These problems will directly lead to abnormal network communication and seriously affect the user experience of TBOX
The existing underlying recovery mechanism of the AG35 module has the problem of being slow or unable to perceive the abnormality of the upper layer, and cannot correct the network abnormality in time

Embodiment 1

[0049] Embodiment 1 provided by the present invention is an embodiment of an AG35 module communication anomaly detection and processing method provided by the present invention, which performs periodic detection processing by setting a detection timer; figure 1 It can be seen that the detection and processing method also includes: setting counters for the number of times of various abnormal states and the number of recovery operations;

[0050] The number of abnormal states includes: the number of abnormal SIM card status, the number of abnormal network registration and the number of times that the PS domain is in 2G mode;

[0051] The number of recovery operations includes: the number of operations to reset the SIM card, the number of operations to switch flight mode, the number of module restarts, and the number of APN redials.

[0052] It can be understood that, in the specific implementation, the counts of the number of abnormal states and the number of recovery operations...

Embodiment 2

[0085] Embodiment 2 provided by the present invention is an embodiment of an AG35 module communication anomaly detection and processing system provided by the present invention, figure 2 A structural diagram of a communication anomaly detection and processing system for an AG35 module provided in an embodiment of the present invention, combined with figure 2 It can be seen that this embodiment includes: performing periodic detection processing by setting a detection timer; sequentially detecting whether the working status of each testing item is abnormal, and detecting that the working status of any testing item is normal, and then detecting the status of the next testing item. Working status; when the working status of any detection item is detected to be abnormal, perform step 2; the detection items are: SIM card status, module working mode, CS domain PS domain registration status, PS domain network standard and APN connection status ; Execute one or more of the various re...

Abstract

The invention relates to a communication anomaly detection processing method and system for an AG35 module, and the method comprises the steps: 1, sequentially detecting whether the working state of each detection item is abnormal or not, and detecting the working state of the next detection item after the working state of any detection item is detected to be normal; when it is detected that the working state of any detection item is abnormal, executing the step 2; the detection items are an SIM card state, a module working mode, a CS domain and PS domain network injection state, a PS domain network type and an APN connection state in sequence; 2, one or more of recovery operations are executed in sequence, the corresponding detection item is executed immediately after each recovery operation is executed, the recovery operations sequentially include switching on and off the flight mode, resetting the SIM card and restarting the module, abnormal links affecting communication can be found timely and accurately, corresponding recovery strategies can be executed, it is guaranteed that network problems can be recovered rapidly, and the detection efficiency is improved. And user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication abnormality detection and processing method and system of an AG35 module. Background technique [0002] At present, the AG35 module used in the vehicle-mounted TBOX (Telematics Box, Internet of Vehicles system) can usually complete the network registration process independently under normal circumstances, and then realize dial-up Internet access through the APP. However, in many abnormal scenarios, the AG35 module may fail to initialize the SIM card, the module is in flight mode, the network registration fails, the module is always in 2G mode, APN (AccessPoint Name, access point) dialing fails, and the call falls back to 2G However, after hanging up the phone, I cannot quickly return to 4G, APN dialing is successful but the network connection is not available, and a series of problems. These problems will directly lead to abnormal network communicat...
