Solution Overview

Problem

Users are often unable to access multiple data networks simultaneously with their mobile terminals due to configuration limitations, and establishing an authenticated connection with one network can be time-consuming, making it difficult to quickly access emergency services or local services available on other networks.

Innovation Solution

A method and apparatus that enable a mobile terminal to rapidly access a second data network in a non-authenticated manner by acquiring supplementary access data from a first core data network, which includes parameters such as data transmission timing, security keys, and protocols, allowing for emergency calls or local services without the need for full authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a user performs full authentication to access a data network, then access reliability is improved, but setup time increases

Engineering Contradiction:
Improveaccess reliabilityVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring the mobile terminal with network access parameters (such as APN settings, authentication credentials, and network selection criteria) before the user needs to access the network. This allows the terminal to quickly establish a connection without performing full authentication procedures from scratch, thus reducing setup time while maintaining reliable access.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If a mobile terminal is configured to communicate with only one data network, then device complexity is reduced, but adaptability decreases

Engineering Contradiction:
Improveconfiguration complexityVSAvoidnetwork access adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements universality by configuring the mobile terminal to store and switch between multiple data network parameters and access configurations. The terminal maintains a unified communication interface that can adapt to different network types (e.g., GSM, CDMA, WiFi) by selecting appropriate parameters from stored configurations, enabling multi-network capability without requiring separate dedicated configurations for each network type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Area of stationary object

If a user is located in access regions of multiple data networks, then coverage area increases, but ease of operation decreases

Engineering Contradiction:
Improvecoverage areaVSAvoidnetwork selection ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies self-service by implementing automatic network selection and handover functionality in the mobile terminal. When the terminal detects its location in a multi-network access region, it automatically evaluates available networks based on pre-configured criteria (such as signal strength, network type preferences, and available services) and autonomously selects the optimal network without requiring user intervention. This maintains ease of operation while providing comprehensive multi-network coverage.

Inventive Principle:
Principle #25Self-service

AI summary

One method includes setting up an authenticated communication session between a mobile terminal and a first core data network. The method includes acquiring, at the first core data network, supplementary access data usable by the mobile terminal to set up a non-authenticated communication session with a second data network and then, transmitting the supplementary access data from the first core data network to the mobile terminal. The second data network is accessible to the mobile terminal.
