Solution Overview

Problem

Current multi-RAT user equipment cannot simultaneously access and transmit/receive data through multiple radio access technologies, leading to inefficiencies in system performance and lack of interworking between wireless LAN and cellular networks.

Innovation Solution

A method for updating base station information in a converged network, allowing simultaneous access by user equipment to multiple communication systems, involving message exchange for updated information such as identifiers, frequency channels, bandwidth, location, and interference data between base stations, enabling efficient interworking between cellular and wireless LAN systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional multi-RAT technology is used, then connection is established to specific RAT based on UE request, but the UE cannot simultaneously access multiple RATs leading to low system efficiency

Engineering Contradiction:

Improvesystem efficiencyVSAvoidmulti-RAT access capability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic RAT selection and simultaneous access management by enabling the UE to actively switch between and access multiple RATs (cellular and WLAN) based on real-time network conditions and service requirements, rather than being statically bound to a single RAT

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent makes the UE multi-functional by enabling simultaneous access to multiple RATs (both cellular and WLAN networks), allowing the device to perform communication functions across different network types concurrently, thereby improving overall system efficiency and resource utilization

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If interworking between wireless LAN and cellular network is not implemented, then conventional multi-RAT technology can be maintained, but overall system efficiency remains low

Engineering Contradiction:

Improveoverall system efficiencyVSAvoidinterworking complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an interworking mechanism that acts as an intermediary between the cellular network and WLAN, enabling coordinated communication and information exchange between the two different network types through standardized protocols and interfaces

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges the cellular network and WLAN into a unified converged network architecture, allowing seamless integration of both networks at the UE level and enabling simultaneous access and coordinated resource management across different network types

Inventive Principle:

Principle #5Merging (Combining)

AI summary

This method whereby abase station in a first communication system updates base station information in a converged network supporting multiple communication systems may comprise the steps of: receiving a first message including changed information from a base station in a second communication system if information from and related to the base station in the second communication system has changed or if information related to the base station in the first communication system has changed; and updating with the changed information on the basis of the first message.
