NR-V2X Terminal Connection Management via QoS Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection management mechanisms in NR-V2X systems lack a specific plan for managing connections between terminals, particularly for unicast and multicast services, which hinders efficient QoS parameter-based connection operations.
Innovation Solution
A method and apparatus for connection management that involve sending and receiving request messages carrying QoS parameters between terminals to perform connection operations, such as establishing, modifying, or releasing connections, using signaling interactions to realize specific QoS flows, including parameters like PQI, VQI, data rate, and communication range requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection management mechanism is designed for NR-V2X unicast and multicast services, then connection management capability is improved, but system complexity increases
Solution Approach 1:
The connection management mechanism is segmented into distinct operational modes (unicast and multicast) with specific QoS parameter sets for each. The system divides connection management into separate procedures for service establishment, modification, and release, allowing each segment to be optimized independently without increasing overall system complexity
Solution Approach 2:
A universal connection management framework is designed that can handle both unicast and multicast services through a common signaling interface. The PC5 signaling protocol is extended to support multiple service types using the same basic message structures, reducing the need for separate complex management systems for each service type
2Reliability
If QoS parameter-based connection operations are implemented, then service quality is improved, but signaling overhead increases
Solution Approach 1:
Multiple QoS parameter updates and connection operations are merged into single signaling messages where possible. The mechanism combines service establishment, QoS parameter configuration, and connection identification into unified PC5 signaling exchanges, reducing the total number of separate signaling messages required
Solution Approach 2:
The system uses parameter encoding and compression techniques to represent QoS parameters efficiently in signaling messages. QoS parameter sets are optimized to include only necessary parameters for each service type, and parameter values are encoded using compact representations that reduce message size while maintaining full QoS control capability

AI summary
Disclosed are a connection management method, and a computer device. The method includes sending, by a first terminal, a request message carrying a first QoS parameter to a second terminal. The request message is used for indicating to perform a connection operation between the first terminal and the second terminal according to the first QoS parameter. The connection between the first terminal and the second terminal includes connection for QoS flow, and the connection operation includes at least one of the following: establishing a connection between the first terminal and the second terminal, modifying the connection between the first terminal and the second terminal, or releasing the connection between the first terminal and the second terminal.
