Network connection management method and terminal device

Abstract

Embodiments of the present disclosure provide a network connection management method and a terminal device, wherein the method includes: when a mobile network needs to be accessed, a communication processor in a communication module prepares an electronic SIM card through a preset in the communication module Access the mobile network; the communication processor will prepare the electronic SIM card for deactivation and activate the official electronic SIM card, and try to use the official electronic SIM card to connect to the mobile network; the communication processor checks whether the currently activated electronic SIM card is ready for electronic SIM. If the SIM card is, then according to the different network connection management behavior requests of the application processor, it returns that the official electronic SIM card does not exist or the network is not connected; if not, it responds to the network connection management behavior requested by the application processor. The embodiments of the present disclosure provide a network connection management solution for a communication module, so that the preparation of the electronic SIM card and the official electronic SIM card work together, and the existing usage mode of the application processor is not affected.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a network connection management method and a terminal device. Background technique [0002] eSIM (embedded-SIM, also known as electronic SIM) card is a new generation of SIM (SubscriberIdentity Module, subscriber identity module) card technology. Its basic feature is to download and install SIM card data through network transmission. in the terminal device. In order to realize the electronic SIM card download function, the terminal needs to have networking capability. However, the electronic SIM card itself is used for networking. In the case that the electronic SIM card has not been obtained, the terminal needs to adopt an additional method for networking. [0003] For consumer terminals, you can connect to the Internet through Wi-Fi, Bluetooth, etc., but for IoT terminals, these conditions are likely not available. In order to solve the initial network...

AI Technical Summary

Problems solved by technology

[0005] The current communication module does not use the prepared electronic SIM card, only the official electronic SIM card, and its network connection management behavior (such as enabling, disabling, connecting, disconnecting, querying, data sending and receiving, etc.) is completely controlled by the application processor through AT commands

After the communication module uses the preparation of the electronic SIM card, because the network connection related to the preparation of the electronic SIM card is not controlled by the application processor, another set of network connection management functions needs to be provided for the preparation of the electronic SIM card, resulting in the preparation of the electronic SIM card. The card cannot work with the official electronic SIM card, which increases the complexity of network connection management accordingly
