Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently requesting position-based system information, particularly in 5G networks, which are crucial for providing location-specific services in IoT environments.

Innovation Solution

A method and apparatus for a terminal to request positioning system information by selecting an uplink type and transmission method based on RSRP threshold conditions, using either normal or supplementary uplinks, and transmitting messages through Msg 1 or Msg 3, with configuration information included in System Information Block 1 (SIB1).

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal uses existing methods to request system information in 5G networks, then basic communication functionality is maintained, but position-based system information cannot be efficiently requested, limiting location-specific services

Engineering Contradiction:
Improveposition-based system information request capabilityVSAvoidposition detection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the system information request process by introducing separate configuration information for position-based system information requests in SIB1. This allows the terminal to specifically request positioning-related system information through dedicated RRC messages, rather than using generic system information request methods, thereby enabling position-based services while maintaining reliability through structured configuration.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the terminal requests positioning system information through standard procedures, then general system information is obtained, but position-specific information requests are not optimized, reducing service efficiency

Engineering Contradiction:
Improvepositioning service provision efficiencyVSAvoidpositioning system information acquisition
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements preliminary action by pre-configuring position-based system information request parameters in SIB1 before the terminal needs to request positioning information. The terminal can directly use these pre-configured parameters to construct positioning information requests, eliminating the need to negotiate parameters during the request process and ensuring complete positioning system information is acquired without loss.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If existing system information request methods are used, then communication protocol compatibility is maintained, but position-based service requirements are not met, reducing service functionality

Engineering Contradiction:
Improvelocation-based service supportVSAvoidsystem information request mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a multi-functional system information request mechanism that can handle both general system information requests and position-based system information requests through a unified framework. The same RRC message structures and configuration methods are used for both types of requests, with position-specific parameters added to the existing SIB1 configuration, thereby supporting location-based services without significantly increasing device complexity.

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