ProSe Control Apparatus QoS Requirement Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inter-terminal direct communication technologies do not ensure Quality of Service (QoS) requirements for requested radio terminals, potentially leading to inadequate throughput or transmission delay in ProSe communication.
Innovation Solution
A control apparatus and method that receive a start request for ProSe communication from a first radio terminal and the QoS requirement from a second radio terminal, allowing for the determination and setup of ProSe communication paths that meet the required QoS, ensuring better communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inter-terminal direct communication is established without considering QoS requirements, then communication setup is simple and fast, but the communication quality (throughput and transmission delay) cannot be ensured
Solution Approach 1:
The control apparatus obtains QoS requirements from the requested terminal before establishing the direct communication path. This preliminary action ensures that QoS considerations are integrated into the path setup process, preventing quality issues before they occur rather than addressing them after communication begins
Solution Approach 2:
The control apparatus acts as an intermediary between the requesting terminal and the requested terminal. It collects QoS requirements, determines appropriate communication paths, and manages the direct communication setup, thereby simplifying the complexity for individual terminals while ensuring QoS compliance
2Reliability
If QoS requirements are obtained and considered for every direct communication request, then communication quality is ensured, but the control procedure becomes more complex
Solution Approach 1:
The requested terminal autonomously provides its own QoS requirements to the control apparatus. This self-service approach eliminates the need for complex QoS negotiation protocols between terminals, as each terminal independently declares its requirements, simplifying the overall control procedure while maintaining quality assurance

AI summary
A control apparatus (5) operates to: (a) receive from a first radio terminal (1), through a public land mobile network (100), a start request for ProSe communication (103) to be performed between the first radio terminal (1) and a second radio terminal (2) without communicating through the public land mobile network (100); and (b) receive a QoS requirement regarding the ProSe communication (103) from the second radio terminal (102). This contributes, for example, to ensuring QoS in inter-terminal direct communication required by a requested radio terminal, which has been requested by a requesting radio terminal to perform the inter-terminal direct communication.
