In-Vehicle APN Configuration for Flexible Operator Switching
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 functionality.
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 the in-vehicle terminal to access target communication networks using obtained operator and APN information.
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 in changing operators or APN is reduced
Solution Approach 1:
The patent implements dynamic configuration of APN information by allowing the in-vehicle terminal to autonomously select operators and configure APN parameters through user input or automatic acquisition from operator networks, transforming the static eSIM configuration into a dynamic, adaptable system that can change operators and APNs without hardware replacement
Solution Approach 2:
The patent enables changing of network access parameters (operator selection, APN information) without changing the physical eSIM card or terminal hardware. By allowing parameter reconfiguration through user input or automatic acquisition, the system achieves adaptability while maintaining the reliability of eSIM-based network access
2Device complexity
If APN information is fixed during manufacturing, then device complexity is reduced, but adaptability to different operators and regions is limited
Solution Approach 1:
The patent implements self-service configuration where the in-vehicle terminal autonomously acquires APN information from operator networks or receives user input to configure APN parameters. This eliminates the need for complex pre-configuration during manufacturing while enabling adaptability to different operators and regions through automatic or user-driven configuration
Solution Approach 2:
The patent prepares the terminal with the capability to autonomously acquire APN information before actual network access is needed. By pre-configuring the terminal with operator selection interfaces and automatic acquisition mechanisms, the system reduces manufacturing complexity while ensuring adaptability is available when needed

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.
