In-Vehicle APN Configuration for Flexible eSIM Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle communication technologies lack flexibility in configuring Access Point Network (APN) information, limiting users' ability to change operators or APNs, which restricts network access functions and increases costs for consumers and enterprises.
Innovation Solution
An APN information configuration mechanism is introduced into the in-vehicle communication standard protocol, allowing users to autonomously select operators and configure APN information, enabling local activation of eSIM services using target APN, profile, and activation code, without requiring new devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eSIM is used to provide network access function, then network access capability is improved, but flexibility of configuring APN information deteriorates
Solution Approach 1:
The patent introduces a dynamic configuration mechanism for APN information through the V2X communication module. The system can dynamically switch between pre-configured APN information and user-selected APN information based on service requirements. The V2X module receives APN information from the server, manages multiple APN configurations, and enables flexible switching without hardware changes, resolving the contradiction between reliable network access and configuration flexibility.
2Adaptability or versatility
If operator or APN needs to be changed, then user requirement for service selection is improved, but device replacement requirement increases
Solution Approach 1:
The patent implements a virtualization approach where multiple APN information sets are stored and managed within the V2X communication module of the same device. Instead of requiring physical eSIM card changes or device replacement, the system copies and switches between different APN configuration sets. The V2X module receives and manages multiple APN information copies from the server, allowing users to select different operators or APNs without any hardware changes.
3Adaptability or versatility
If multiple APNs are configured, then network access options are improved, but configuration complexity increases
Solution Approach 1:
The patent introduces the V2X communication module as an intermediary between the user, the server, and the network access function. This intermediary module automatically receives, manages, and switches between multiple APN information sets from the server. Users simply select from presented options without dealing with complex configuration details, as the V2X module handles the complexity of managing multiple APN configurations, switching between them based on service requirements.

AI summary
Embodiments of this application provide an in-vehicle communication method, apparatus, and system, and relate to the field of in-vehicle communication technologies. The method includes: A first node obtains target APN information of the first node based on information about an operator that provides a service for the first node, where the target APN information indicates at least two APNs, and the at least two APNs include a customized APN of the first node; and accesses a target communication network based on the information about the operator and the target APN information. In the method, the required target APN information may be flexibly configured for the first node based on a service requirement of the first node, so that the first node accesses the target communication network.
