Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing communication connections for proximity-based services, particularly in determining whether a communication connection is within or out of the proximity range, leading to potential resource wastage and service anomalies.

Innovation Solution

A method and apparatus where User Equipment (UE) in a wireless communication system transmit messages to request a Radio Resource Control (RRC) connection, including information about the cause of the request, and receive responses from a ProSe server to determine if the connection is within proximity range, allowing for requests to extend or release the connection accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a communication connection is established for proximity-based service without verifying proximity range, then the service can be initiated quickly, but resource wastage occurs when devices are actually out of range

Engineering Contradiction:
Improveservice initiation speedVSAvoidresource wastage
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system performs preliminary proximity verification by receiving a second message from the ProSe server that indicates whether the communication connection is within proximity range before allowing the service to proceed. This preliminary check prevents resource wastage by identifying out-of-range connections early in the process, while still allowing quick service initiation for in-range devices.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The ProSe server provides feedback through the second message indicating whether the communication connection is within proximity range. This feedback mechanism enables the system to adjust resource allocation based on actual proximity status, preventing energy wastage on out-of-range connections while maintaining fast service initiation for valid connections.

Inventive Principle:
Principle #23Feedback

2Loss of energy

If the system continuously monitors proximity range to prevent resource wastage, then resource efficiency improves, but system complexity increases

Engineering Contradiction:
Improveresource efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

Instead of continuous monitoring, the system performs a single preliminary proximity verification by receiving the second message from the ProSe server after connection establishment. This preliminary check achieves resource efficiency without requiring complex continuous monitoring infrastructure, thereby avoiding increased system complexity.

Inventive Principle:
Principle #10Preliminary action

3Loss of energy

If the system releases communication connections immediately when out of proximity range, then resource efficiency improves, but service reliability may be compromised

Engineering Contradiction:
Improveresource efficiencyVSAvoidservice reliability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The system performs preliminary proximity verification by receiving the second message indicating proximity status before allowing service to proceed. For out-of-range connections, the system requests either proximity range extension or communication connection release, ensuring that resources are efficiently managed while maintaining service reliability through proper protocol-based connection management.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method and apparatus are described for managing a communication connection by a User Equipment (UE) in a wireless communication system. In one embodiment, a first message is transmitted for requesting a Radio Resource Control (RRC) connection. The first message includes a cause of the request related with a Proximity-based Service (ProSe), and an identifier randomly generated for the communication connection by the UE and set to be effective for a predetermined time. The communication connection is established via a network path. A second message is received from a ProSe server. The second message indicates whether the communication connection is out of proximity range or not. When the second message indicates that the communication connection is out of the proximity range, a third message for requesting one of a proximity range extension and a communication connection release is transmitted to the ProSe server.
