Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

In the present examples, "first", "second", etc. are used for distinguishing different objects, and are not used for describing a specific order or sequence.

The T-BOX main module is an MCU and a networking module: the system comprises an NAD module (4G/5G module), wherein the NAD module is mainly responsible for 4G/5G network connection and data interaction outside the vehicle, and the MCU is mainly responsible for vehicle data interaction processing.

Example one

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:

In this embodiment, as shown in fig. 2, the power mode is set by distinguishing the network searching and network residing time, which may be specifically implemented by the following method:

the network searching and network parking are designed to be carried out when the NAD module is started and initialized, if the network parking 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 parking succeeds, and dialing is initiated even if the network parking fails, so that the dialing condition is simplified;

because the network searching and residing is usually packaged and designed by a 4G/5G module supplier, the upper layer can develop the network searching and residing frequency and cannot intervene the bottom layer flow of single network searching and residing, therefore, the dialing strategy is not designed to depend on the network searching and residing strategy. When the T-BOX is restarted, a dialing flow is initiated (dialing is initiated when the network residence fails, and the dialing fails to enter the redialing strategy of the invention).

The first preset time T1 is designed to be the network searching time interval when the vehicle is OFF, 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, and the storage battery feeding condition 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 the mode can be designed according to the response performance of the vehicle to the T-BOX, such as 10s in fig. 2.

In the present embodiment, a dial trigger condition is set:

dialing triggering conditions are as follows: the T-BOX restarts.

Further designing a T-BOX restarting condition:

(1) the vehicle is connected with a battery power supply for the first time;

(2) setting a soft button on a vehicle interface to manually operate T-BOX to restart;

(3) and the vehicle is automatically restarted 15min after being turned OFF, wherein the restarting time can be determined according to actual needs and is not limited to 15 min.

Once the vehicle is successfully dialed, the network is kept connected, the network is not actively disconnected when the restarting condition is not met, the service response timeliness is provided, and the time delay caused by re-dialing the network after each service is initiated is avoided.

In the OFF state, restarting the T-BOX only triggers one-time dialing; and in the non-OFF state, the T-BOX is restarted, and if the dialing fails, a redialing strategy is entered.

As shown in fig. 1, the specific implementation process of the single APN vehicle network connection dialing method of this embodiment is as follows:

entering a dialing flow after the T-BOX is restarted;

after receiving the sign that the network side returns the success of dialing, storing information such as an IP address, a DNS server and the like, and considering that the dialing is successful only when the network session needs to keep the connection for more than a third preset time (such as 1 minute in figure 1), and resetting the redialing interval to the preset redialing time (such as 5 s); returning a dialing failure mark or entering a redialing process if the network session does not keep the connection for more than third preset time;

if the redialing fails, the redialing interval is increased, for example, the redialing interval can be set to be 5, 10, 15, 20, 25, 30, 60, 90, 120, 150, 180 and 180s, as shown in the following table 1, if the continuous redialing fails to exceed a first preset number of times (a dialing interval counter Z: after the redialing continuous failure Z times, the flight mode is switched once, for example, 5 times are set), the flight mode (CFUN for short) is switched once, then redialing is continued, if the continuous CFUN switching exceeds a second preset number of times (a CFUN switching counter Y: after the CFUN is switched for continuous Y times, the dialing fails, the networking module NAD is restarted, for example, 3 times are set), and the internal 4G/5G networking module (NAD for short) is restarted.

The CFUN switching means starting and closing a flight mode once, and triggering network searching and network parking and dialing processes to be carried out again.

If the actual vehicle gear is OFF, dialing is only carried out once for each APN after the T-BOX is restarted, and the redialing strategy is not participated in.

TABLE 1

n	Xn	n	Xn
				n＝1	Xn＝5s	n＝6	Xn＝30s
n＝2	Xn＝10s	n＝7	Xn＝60s
				n＝3	Xn＝15s	n＝8	Xn＝90s
n＝4	Xn＝20s	n＝9	Xn＝120s
				n＝5	Xn＝25s	n≥10	Xn＝180s

In table 1, n represents the cumulative redial number, and Xn represents the preset redial time, i.e., the dialing interval, which represents the Xn time redial interval 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:

In this embodiment, the network searching and network residing operation is the same as that of the single APN, and the network searching and network residing time distinguishing power mode is set specifically by the following means:

In the present embodiment, a dial trigger condition is set:

dialing triggering conditions are as follows: the T-BOX restarts.

Further designing a T-BOX restarting condition:

(1) the vehicle is connected with a battery power supply for the first time;

As shown in fig. 3, the specific implementation process of the multi-APN vehicle network connection dialing method of this embodiment is as follows:

a multi-path APN counter i is designed, and in this embodiment, policy description is performed by taking a three-path ANP as an example:

entering a dialing flow after the T-BOX is restarted;

starting to configure an ith path of APN (access point name) (i) information, APN (access point name) (i) request dialing, wherein i is 0,1,2, after receiving a sign that a network side returns successful dialing, storing information such as an IP address and a DNS (domain name server) server, considering successful dialing only when a network session needs to keep connection for more than a third preset time (such as 1 minute), and resetting a redialing interval to a preset redialing time (such as 5 s); returning a dialing failure mark or entering a redialing process if the network session does not keep the connection for more than third preset time;

if the redialing fails, the redialing interval is increased, for example, the redialing interval can be set to be 5, 10, 15, 20, 25, 30, 60, 90, 120, 150, 180 and 180s, if the continuous redialing fails to exceed the first preset times (a dialing interval counter Z: after the redialing fails to continue for Z times, the flight mode is switched once, for example, 5 times are set), CFUN switching is performed once, then redialing is continued, and if the continuous CFUN switching exceeds the second preset times (a CFUN switching counter Y: after the CFUN switching continues for Y times, the dialing fails, the networking module NAD is restarted, for example, 3 times are set), the NAD is restarted.

Wherein, CFUN switching indicates a primary flight mode of a switch, and triggers to search for the network again and park the network. And after the flight mode is switched on and off, disconnecting APNs which are successfully dialed, clearing the information of the last dialing of all APNs, and redialing.

If the actual vehicle gear is OFF, each APN only tries to dial once after the T-BOX is restarted, and the redialing strategy is not participated.

And repeating the steps until the 3-way APN dialing is completed.
