Data Channel Tagging for Multi-Channel 5G Application Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in 5G NR, face challenges in establishing multiple data channels (DCs) for applications like augmented reality due to insufficient information in the data channel application identifier (DC ID) regarding DC characteristics, leading to inefficient network resource utilization.
Innovation Solution
The proposed solution involves extending the DC application ID with a DC tag that provides characteristics of each DC, allowing UEs and network entities to establish multiple DCs without additional signaling or route lookups, thereby optimizing network resource usage.

Engineering Contradiction Analysis
1Loss of information
If the DC application ID is used to identify data channels, then the application can be associated with DCs, but the DC characteristics information is insufficient leading to inefficient network resource utilization
Solution Approach 1:
The DC identification is segmented into two parts: the existing DC application ID and a new DC tag. The DC application ID identifies the application, while the DC tag provides additional DC-specific characteristics. This segmentation allows both application-level and channel-level information to be conveyed without increasing overall complexity.
Solution Approach 2:
The DC tag is nested within the DC identification structure, complementing the existing DC application ID. This nested approach allows the DC characteristics to be embedded within the existing identification framework, enabling efficient routing decisions without requiring a complete redesign of the identification system.
2Adaptability or versatility
If multiple DCs are established for an application, then communication flexibility is improved, but additional signaling and route lookups are required increasing system complexity
Solution Approach 1:
The DC tag is pre-configured and included in the DC identification information before the actual data transmission. This preliminary inclusion of routing information eliminates the need for additional signaling and route lookups during data transmission, reducing real-time processing complexity.
Solution Approach 2:
The DC tag contains sufficient routing information that enables the system to automatically determine the appropriate data channel without requiring external signaling or complex route lookups. The identification structure itself provides the necessary information for routing decisions.
