Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoS solutions in mobile communication networks fail to effectively distinguish and meet the diverse quality of service requirements for different types of data streams, leading to inefficient resource utilization and suboptimal user experience.
Innovation Solution
A data transmission method that involves determining a mapping relationship between packet filter sets and QoS flows based on characteristic information of a service, allowing for more comprehensive consideration of service requirements, and mapping data packets to appropriate DRBs for differentiated processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing QoS solutions map service flows to QoS flows based on 5-tuple and QFI mapping, then basic QoS differentiation is achieved, but the ability to distinguish and meet diverse quality requirements for different data streams is insufficient
Solution Approach 1:
The patent segments the QoS mapping process into two independent stages: first mapping service flows to packet filter sets based on 5-tuple information, then mapping packet filter sets to QoS flows based on characteristic parameters. This segmentation enables fine-grained distinction of different data stream types while maintaining manageable complexity through modular processing.
Solution Approach 2:
The patent introduces a new dimension of classification by adding characteristic parameter-based filtering on top of the traditional 5-tuple mapping. This dimensional extension allows the system to distinguish data streams not only by their basic flow characteristics but also by additional service-specific attributes, thereby enhancing adaptability without overwhelming complexity.
2Productivity
If comprehensive characteristic information is collected and processed for service differentiation, then resource utilization is improved, but processing time and system complexity increase
Solution Approach 1:
The patent performs preliminary mapping of service flows to packet filter sets during service establishment, pre-processing the characteristic information before actual data transmission begins. This preliminary action allows the system to prepare differentiation rules in advance, reducing processing time during active data flow handling while still utilizing comprehensive characteristic information for optimized resource allocation.

AI summary
Method and apparatus provide for receipt by a communication apparatus of first indication information from a second communication apparatus indicating whether a first service of a terminal device is a service of a first type. The communication apparatus obtains characteristic information of the first service based on the first indication information, determines a mapping relationship between a packet filter set of the first service and a quality of service QoS flow based on the characteristic information, and sends the mapping relationship to a third communication apparatus.
