Uplink QoS Processing via Packet Filter Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE system fails to satisfy different Quality of Service (QoS) requirements for various services, as it treats all services multiplexed to the same EPS bearer with the same QoS level, neglecting the unique requirements of individual services.
Innovation Solution
The RAN network element obtains service data of preset granularity, performs QoS classification based on specific QoS requirement parameters, and transmits the data accordingly, allowing for differentiated QoS processing and satisfaction of unique QoS demands for each service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple SDFs are multiplexed to the same EPS bearer using a single QoS parameter, then device complexity and processing overhead are reduced, but the ability to satisfy different QoS requirements of different services deteriorates
Solution Approach 1:
The patent segments QoS processing by introducing packet filters that divide service data flows into different categories. Each packet filter corresponds to specific QoS parameters, allowing different SDFs within the same EPS bearer to be processed according to their specific requirements. This segmentation enables fine-grained QoS control without requiring separate bearers for each service.
Solution Approach 2:
The patent applies local quality by associating different QoS parameters with different packet filters. Each packet filter can have its own QoS parameters (such as priority, bandwidth guarantees, delay tolerances) that are applied locally to matching data packets. This allows specific portions of traffic to receive customized QoS treatment while other traffic follows default parameters.
2Ease of operation
If a single QoS parameter is used for all services in an EPS bearer, then network resource management is simplified, but service-specific QoS performance deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring packet filters with their associated QoS parameters before data transmission begins. The network elements (such as P-GW and RAN) are pre-provisioned with filter rules that automatically match incoming packets to appropriate QoS treatments. This eliminates the need for real-time QoS decision-making for each packet, maintaining operational simplicity while ensuring reliable service-specific QoS performance.
3Productivity
If QoS processing is performed at a single network level, then processing efficiency is improved, but the ability to meet diverse service requirements across different network elements deteriorates
Solution Approach 1:
The patent applies universality by designing packet filters that can be deployed and executed at multiple network elements (P-GW, RAN, and potentially other intermediaries). The same packet filter configuration can serve multiple functions: traffic classification, QoS parameter application, and policy enforcement across different network domains. This multi-functional approach maintains processing efficiency while extending adaptability across the entire network infrastructure.

AI summary
Embodiments of the present invention provide a data transmission method and apparatus. The method includes: obtaining, by a terminal, to-be-transmitted uplink service data of a preset granularity; obtaining, by the terminal, a QoS requirement parameter corresponding to the to-be-transmitted uplink service data of the preset granularity; and transmitting, by the terminal, the to-be-transmitted uplink service data of the preset granularity based on the QoS requirement parameter corresponding to the to-be-transmitted uplink service data of the preset granularity. Different data processing is implemented for to-be-transmitted uplink service data of preset granularities corresponding to different QoS requirement parameters, so that QoS requirements of uplink service data of different preset granularities are satisfied.
