Embodiment 1

[0041] Please also refer to figure 1 as well as figure 2 , this embodiment provides a method for the NB-IoT module to quickly save and restore the network path in the PSM mode. On the one hand, it can quickly save the parameters of the remote environment when the NB-IoT module pre-enters the PSM mode. In order to ensure the subsequent rapid recovery of the remote environment of the network path, on the other hand, it can quickly restore the network path between the NB-IoT module and the server or cloud platform when the NB-IoT module exits the PSM mode.

[0042] The NB-IoT module of this embodiment is based on the LWM2M open source protocol stack (lightweight Internet of Things communication protocol), and implements the program of the LWM2M client through the wakaama source code in the protocol stack to access the telecom cloud platform or the mobile OneNET IoT platform.

[0043] see image 3 , when the NB-IoT module registers, the client can first establish the LWM2M ope...

Embodiment 2

[0065] see Figure 4 , this embodiment provides a method for the NB-IoT module to quickly save and restore the network path in PSM mode, which adds the following steps on the basis of Embodiment 1 (after judging again whether the NB-IoT module sends the server before successful registration):

[0066] When the NB-IoT module is not successfully registered, determine whether the registration time has expired;

[0067] When the registration time expires, you can send a registration exception message first, and then jump to the end, or you can directly jump to the end;

[0068] When the registration time has not expired, continue to wait for the registration, and after a period of time, judge whether the registration time has expired again, and repeat the above steps.

Embodiment 3

[0070] This implementation provides a device for the NB-IoT module to quickly save and restore the network path in the PSM mode, which uses the method of the NB-IoT module in Embodiment 1 or Embodiment 2 to quickly save and restore the network path in the PSM mode . The device includes a preservation module and a restoration network access module.

[0071] The saving module is used to determine whether the NB-IoT module is successfully registered with the server when the NB-IoT module pre-enters the PSM mode. The saving module is also used to save the parameters of the remote environment corresponding to the server to the file system when the NB-IoT module is successfully registered.

[0072] The recovery network access module is used to recover the parameters of the remote environment stored in the file system when the NB-IoT module receives the trigger signal of pre-exiting the PSM mode. The network access recovery module is also used to determine whether the parameters of...

Abstract

The invention discloses a method and a device for storing and recovering a network path, a terminal and a storage medium. The invention particularly relates to a method for quickly saving and restoring a network path under a PSM model where a NB-IoT module is located. The method comprises the following steps: determining whether the IoT module is registered with a server successfully or not; whenthe NB-IoT module is registered successfully, storing parameters of a remote environment corresponding to the server to the file system; when a trigger signal of pre-exiting from the PSM mode is received, recovering parameters of a remote environment stored in the file system; judging whether the parameters of the remote environment return to normal or not; when the parameters of the remote environment return to normal, judging whether updating and registering are needed or not; and when the registration needs to be updated, updating the registration information, and transmitting data to execute client service. According to the invention, the processing flow after PSM wake-up is optimized, and data can be directly transmitted without starting a registration flow, so that the wake-up time consumption in a low power consumption state is reduced, and instantaneity of an NB-IoT application situation is ensured.

Description

technical field [0001] The present invention relates to a method for quickly saving and restoring a network path in the technical field of the Internet of Things, in particular to a method for quickly saving and restoring a network path for an NB-IoT module in PSM mode, and also relates to a method for quickly saving and restoring a network path device, computer terminal, computer readable storage medium. Background technique [0002] At present, in NB-IoT (narrowband Internet of Things) application scenarios, due to the power consumption requirements of IoT equipment and its battery power supply characteristics, there are two solutions to achieve low power consumption: the first solution, NB-IoT When the module is not doing business, the whole machine performs power-off processing on it to save power consumption; in the second solution, when the NB-IoT module is not doing business, the whole machine performs PSM mode (power saving mode, that is, Low Power Mode) setting to ...
