Mobile Network Access Mode Identification via Gateway IP Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network service providers face challenges in accurately determining the network access modes of mobile devices due to unauthorized changes in Access Point Names (APNs) and difficulties in obtaining APNs from certain devices, leading to a high error rate in identifying network access modes.
Innovation Solution
A method and system that obtain network connection information and access point information to determine the network access mode, using a mapping table to match APNs or wireless gateway IP addresses with corresponding network access modes, thereby improving accuracy in identifying network access modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network service providers use APN to identify network access modes, then the identification process is simple, but the accuracy is low due to unauthorized changes and difficulty in obtaining APNs from certain devices
Solution Approach 1:
The patent introduces a gateway IP address as an intermediary indicator to determine network access modes. Instead of directly relying on APN which can be modified or unavailable, the system uses the gateway IP address obtained from network connection information as a mediator to indirectly identify the network access mode, thereby improving accuracy while maintaining operational simplicity
Solution Approach 2:
The patent performs preliminary acquisition of network connection information including gateway IP address before attempting to use APN for identification. By having the gateway IP address readily available in advance through network connection data, the system can fall back to this reliable indicator when APN is unavailable or suspicious, ensuring accurate identification without compromising the simplicity of the process
2Ease of operation
If network service providers manually check APNs from mobile devices, then the process is straightforward, but the error rate is high due to unauthorized changes by users
Solution Approach 1:
The patent implements a feedback mechanism where the system first attempts to obtain APN from the mobile device, then verifies its reliability by cross-checking with network connection information and gateway IP address. If the APN appears to be unauthorized or inconsistent, the system feedbacks to use the gateway IP address instead, thereby reducing errors while keeping the checking process straightforward
Solution Approach 2:
The system performs preliminary verification of the obtained APN by comparing it with expected values or checking its consistency with network connection data before finalizing the network access mode determination. This preliminary action prevents unauthorized APN changes from causing errors, while the overall process remains straightforward by automatically handling the verification
