Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional methods for setting access point names (APN) in mobile devices are inadequate for timely changes, especially in regional activities, as they do not allow for dynamic adaptation to provide differentiated services based on user location.

Innovation Solution

A method and device for adaptively setting APN by transmitting broadcast messages or EPS mobility management information from a base station to a mobile device, including APN data for establishing packet data network connectivity to access services, enabling automatic APN management and setting upon entering a specific area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional application methods (SIM interface or TCP/IP protocol) are used to set APN, then APN control can be realized, but the system cannot timely change the APN to achieve special applications in regional activities

Engineering Contradiction:

ImproveAPN adaptability to regional activitiesVSAvoidTime delay in APN change

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic APN configuration by having the base station broadcast APN information through system broadcast messages or EMM messages. The APN settings are no longer static but dynamically updated based on the mobile device's location and service area, allowing timely adaptation to regional activities without manual intervention

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mobile device automatically receives and applies APN configuration information from the base station through broadcast messages or EMM messages. This self-service mechanism eliminates the need for manual APN setting by users or complex interaction through SIM interface/TCP/IP protocols, enabling automatic adaptation to regional services

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual APN setting methods are used, then users have control over APN configuration, but users cannot obtain location-specific services automatically and may incur additional data usage

Engineering Contradiction:

ImproveAutomatic APN configurationVSAvoidLocation-specific service information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where the base station monitors the mobile device's location and service area, then automatically sends appropriate APN configuration information through broadcast messages or EMM messages. This closed-loop feedback ensures the mobile device receives the correct location-specific service information without user intervention

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The base station pre-configures APN information for different service areas and proactively broadcasts this information to mobile devices entering those areas. This preliminary preparation of service information allows automatic APN configuration before the user even requests the service, eliminating the need for manual setup

Inventive Principle:

Principle #10Preliminary action
