Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
In the examples of the present invention, "first," "second," etc. are used to distinguish between different objects, and are not used to describe a particular order or sequence.
The T-BOX main module comprises an MCU and a networking module: NAD module (4G/5G module) constitutes, and wherein, NAD module is mainly responsible for 4G/5G network connection and the data interaction outside the car, and MCU is mainly responsible for vehicle data interaction processing.
Example 1
Fig. 1 is a schematic flow chart of a single APN vehicle network connection dialing method according to an embodiment of the present invention, including:
the method comprises the steps that network searching and network residing operation is carried out when a networking module in a T-BOX is started and initialized, dialing is carried out when the T-BOX is restarted, when a vehicle power supply gear is OFF, the T-BOX is restarted to trigger dialing only once, networking is kept after dialing is successful, the network is not actively disconnected when a T-BOX restarting condition is not achieved, and redialing is not carried out when dialing fails;
when the power supply gear of the vehicle is not OFF, after the T-BOX is successfully restarted and dialled, the network is kept on, the network is not actively disconnected when the T-BOX restarting condition is not reached, and if the dialling fails, the redialing is carried out;
when the dialing fails and needs to be redialed, redialing is carried out after waiting for preset redialing time, flight mode switching is carried out after the number of redialing continuous failures is larger than the first preset number of times, and if the number of flight mode continuous switching is larger than the second preset number of times, the networking module is restarted.
In this embodiment, as shown in fig. 2, the network searching and residence time distinguishing power mode is set, which may be specifically implemented by the following manner:
the network searching operation, the network residence operation and the like are designed to be performed when the NAD module is started and initialized, if the network residence fails, different network searching time intervals are designed according to different power supply gears, the remote monitoring terminal searches the network all the time until the network residence is successful, dialing is initiated even if the network residence fails, and dialing conditions are simplified;
because the network searching and residing is often encapsulated and designed by a 4G/5G module provider, the upper layer can develop the network searching and residing frequency and cannot interfere with the network searching and residing bottom layer flow of a single network searching and residing, and therefore, the design dialing strategy does not depend on the network searching and residing strategy. The T-BOX will initiate the dialing process when restarting (initiate dialing when failing to reside in the network, will dial failure to enter the redial strategy of the invention too).
The first preset time T1 is designed to be the network searching time interval when the vehicle is OFF, and the calculation design can be carried out according to the dark current of the vehicle and the current consumption condition when the T-BOX searches the network, so that the feeding condition of the storage battery is avoided. Such as 300s in fig. 2.
The second preset time T2 is designed as a network searching time interval when the vehicle is not OFF, and in this mode, the design can be performed according to the response performance of the vehicle to the T-BOX, for example, 10s in fig. 2.
In this embodiment, a dial trigger condition is set:
dialing trigger condition: the T-BOX is restarted.
Further design T-BOX restart conditions:
(1) The vehicle is connected with a battery power supply for the first time;
(2) Setting a soft button of a vehicle-computer interface to manually operate the T-BOX for restarting;
(3) The vehicle is automatically restarted 15min after being OFF, wherein the restarting time can be determined according to actual needs and is not limited to 15min.
Once dialing is successful, the vehicle keeps networking, the network is not actively disconnected when the restarting condition is not reached, service response timeliness is provided, and time delay caused by starting service and re-dialing networking each time is avoided.
In the OFF state, the T-BOX is restarted to trigger only one dialing; in the non-OFF state, the T-BOX is restarted, and if dialing fails, the T-BOX enters a redial strategy.
As shown in fig. 1, the implementation procedure of the single APN vehicle network connection dialing method of the present embodiment is as follows:
after restarting the T-BOX, entering a dialing flow;
after receiving the sign that the dialing is successful, the network side stores information such as an IP address, a DNS server and the like, and the network session needs to be connected for more than a third preset time (such as 1 minute in FIG. 1) to consider that the dialing is successful, and at the moment, the redial interval is reset to be a preset redial time (such as 5 s); returning a dialing failure sign or if the network session does not keep connection for more than a third preset time, entering a redialing flow;
if the redial fails, the redial interval is incremented, as may be set to 5, 10, 15, 20, 25, 30, 60, 90, 120, 150, 180s, as shown in table 1 below, if the consecutive redial fails more than a first preset number of times (the dialing interval counter Z: after the consecutive redial fails Z times, the flight mode is switched once, as set 5 times), the flight mode (abbreviated as CFUN) is switched once, and then the redial is continued, if the consecutive CFUN is switched more than a second preset number of times (the CFUN switch counter Y: after the CFUN is switched for consecutive Y times, the dialing still fails, the networking module NAD is restarted, as set 3 times), the internal 4G/5G networking module (abbreviated as NAD) is restarted.
The CFUN switching indicates that a flight mode is turned on and off once, and triggers network searching, network residing and dialing processes to be conducted again.
If the actual gear is OFF, only one dialing is carried out on each path of APN after the T-BOX is restarted, and the redialing strategy is not participated.

In table 1, n represents the cumulative redial times, xn is a preset redial time, that is, a dialing interval, and represents the redial time of interval Xn after the number report failure.
Example two
Fig. 3 is a schematic flow chart of a multi-APN vehicle network connection dialing method according to an embodiment of the present invention, including:
the method comprises the steps that network searching and network residence operation is carried out when a networking module in a T-BOX is started and initialized, current path APN dialing is carried out when the T-BOX is restarted, when a vehicle power supply gear is OFF, the T-BOX is restarted to trigger only one dialing of the current path APN, networking is kept after the current path APN dialing is successful, the current path APN network is not actively disconnected when a T-BOX restarting condition is not reached, when the current path APN dialing fails, current path APN redialing is not carried out, and next path APN dialing is carried out after the current path APN dialing is successful or dialing fails;
when the power supply gear of the vehicle is non-OFF, after the current path APN dialing is successfully triggered by the T-BOX restarting, the current path APN networking is kept, the current path network is not actively disconnected when the T-BOX restarting condition is not met, next path APN dialing is carried out, and if the current path APN dialing fails, the current path APN redialing is carried out;
when the current road APN dialing fails and needs to be redialed, the current road APN redialed is carried out after waiting for the preset redialing time, the current road APN flight mode switching is carried out after the continuous redialing failure times of the current road APN are larger than the first preset times, and the networking module is restarted if the current road APN still fails to dial after the continuous switching times of the current road APN flight mode are larger than the second preset times.
In this embodiment, the network searching and residing operation is the same as that of a single APN, and the network searching and residing time distinguishing power mode is set, which can be specifically implemented by the following modes:
the network searching operation, the network residence operation and the like are designed to be performed when the NAD module is started and initialized, if the network residence fails, different network searching time intervals are designed according to different power supply gears, the remote monitoring terminal searches the network all the time until the network residence is successful, dialing is initiated even if the network residence fails, and dialing conditions are simplified;
because the network searching and residing is often encapsulated and designed by a 4G/5G module provider, the upper layer can develop the network searching and residing frequency and cannot interfere with the network searching and residing bottom layer flow of a single network searching and residing, and therefore, the design dialing strategy does not depend on the network searching and residing strategy. The T-BOX will initiate the dialing process when restarting (initiate dialing when failing to reside in the network, will dial failure to enter the redial strategy of the invention too).
The first preset time T1 is designed to be the network searching time interval when the vehicle is OFF, and the calculation design can be carried out according to the dark current of the vehicle and the current consumption condition when the T-BOX searches the network, so that the feeding condition of the storage battery is avoided. Such as 300s in fig. 2.
The second preset time T2 is designed as a network searching time interval when the vehicle is not OFF, and in this mode, the design can be performed according to the response performance of the vehicle to the T-BOX, for example, 10s in fig. 2.
In this embodiment, a dial trigger condition is set:
dialing trigger condition: the T-BOX is restarted.
Further design T-BOX restart conditions:
(1) The vehicle is connected with a battery power supply for the first time;
(2) Setting a soft button of a vehicle-computer interface to manually operate the T-BOX for restarting;
(3) The vehicle is automatically restarted 15min after being OFF, wherein the restarting time can be determined according to actual needs and is not limited to 15min.
Once dialing is successful, the vehicle keeps networking, the network is not actively disconnected when the restarting condition is not reached, service response timeliness is provided, and time delay caused by starting service and re-dialing networking each time is avoided.
In the OFF state, the T-BOX is restarted to trigger only one dialing; in the non-OFF state, the T-BOX is restarted, and if dialing fails, the T-BOX enters a redial strategy.
As shown in fig. 3, the implementation procedure of the multi-APN vehicle network connection dialing method in this embodiment is as follows:
a multi-way APN counter i is designed, and in this embodiment, three ways of ANP are taken as an example to perform policy description:
after restarting the T-BOX, entering a dialing flow;
an i-th path APN (i) information is configured, the APN (i) requests dialing, i=0, 1 and 2, after a sign that the network side returns successful dialing is received, information such as an IP address, a DNS server and the like is stored, and network session needs to be kept for connection for more than a third preset time (such as 1 minute) to consider successful dialing, and at the moment, a redial interval is reset to a preset redial time (such as 5 s); returning a dialing failure sign or if the network session does not keep connection for more than a third preset time, entering a redialing flow;
if the redial fails, the redial interval is incremented, which may be set to 5, 10, 15, 20, 25, 30, 60, 90, 120, 150, 180s, if the consecutive redial fails more than a first preset number of times (the dialing interval counter Z: after the consecutive redial fails Z times, the flight mode is switched once, such as 5 times, is set), the CFUN switch is performed once, then the redial is continued, if the consecutive CFUN switch exceeds a second preset number of times (the CFUN switch counter Y: after the CFUN switch continues Y times, the dialing still fails, the networking module NAD is restarted, such as 3 times is set), the NAD is restarted.
The CFUN switches to indicate a one-time flight mode of the switch, and triggers network searching and network residing again. After the flight mode is switched on and off, each path of APNs which are successfully dialed is disconnected, the last dialing information of all APNs is cleared, and the dialing is carried out again.
If the actual gear is OFF, only one dialing is tried for each path of APN after the T-BOX is restarted, and the redialing strategy is not participated.
Repeating the steps until the 3-path APN dialing is completed.
