Solution Overview

Problem

Current wireless communication networks, particularly LTE networks, face challenges in efficiently managing and broadcasting network access data sets for User Equipment (UE) selection among wireless relays, leading to suboptimal UE attachment and service provision.

Innovation Solution

A system where wireless relays transfer relay status data to a network control system, which processes and generates individual network access data sets, and then broadcasts LTE System Information Blocks (SIBs) indicating their capabilities, allowing UEs to select the most suitable relay based on requested services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless relays broadcast generic network information in SIBs, then all UEs can receive basic network access information, but UEs cannot make optimal relay selection based on service-specific requirements

Engineering Contradiction:

ImproveUE relay selection capabilityVSAvoidService-specific network access information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The network access information is segmented into generic SIB content and service-specific network access data sets. Each wireless relay broadcasts its unique network access data set in the SIB-9, allowing UEs to receive differentiated information for optimal relay selection based on service requirements.

Inventive Principle:

Principle #1Segmentation

2Productivity

If a centralized system manages all relay information, then network control is simplified, but relay status data changes cannot be promptly reflected in broadcasts

Engineering Contradiction:

ImproveBroadcast update efficiencyVSAvoidDistributed data management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Wireless relays pre-acquire their individual network access data sets from the network control system and store them locally. When status data changes, relays update their broadcasts autonomously based on pre-configured data, enabling prompt reflections without centralized coordination for each update.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If UEs attach to any available relay, then attachment process is simple, but service quality may be suboptimal

Engineering Contradiction:

ImproveUE attachment simplicityVSAvoidService quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements feedback through SIB-9 broadcasts containing service-specific network access data sets. UEs use this feedback information to make informed relay selection decisions, matching their service requirements with appropriate relay capabilities, thereby improving service quality while maintaining attachment simplicity.

Inventive Principle:

Principle #23Feedback

AI summary

A data communication network to provide network access data sets for User Equipment (UE) selection of a wireless relay. The wireless relays transfer relay status data to a network control system. The network control system processes the relay status data to generate network access data sets for the wireless relays and transfers the individual network access data sets for delivery to the wireless relays. The wireless relays receive their individual network access data sets and wirelessly broadcast relay Long Term Evolution (LTE) System Information Blocks (SIBs) indicating their individual network access data sets. The wireless relays receive wireless UE attachments responsive to the relay LTE SIB broadcasts of the individual network access data sets.
