GW-U GW-C Bearer Processing via Rule Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bearer processing in evolved packet core (EPC) networks is limited by the capability of user equipment (UE) to identify service flows, which restricts the implementation of quality of service (QoS) management.
Innovation Solution
A method and system where a gateway user plane (GW-U) matches data packets with rules to send bearer processing indication information to a gateway control plane (GW-C), allowing GW-C to perform bearer processing based on QoS information without relying on UE's capability to identify service flows, by using QoS information such as QCI and ARP for trigger conditions and packet feature information for binding services to bearers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE identifies service flows to initiate resource requests, then bearer processing can be implemented, but the system is limited by UE capability to identify service flows
Solution Approach 1:
The patent introduces a network-side service flow identification mechanism where the network device (P-GW or PCEF) acts as an intermediary to identify service flows and determine QoS parameters. This replaces the UE-based identification approach, allowing bearer processing to proceed without requiring UE to have service flow identification capabilities. The network device uses packet filtering rules and QoS rules to identify service flows and trigger bearer processing procedures.
2Reliability
If network provides differentiated services based on QoS attributes, then service quality is improved, but the complexity of QoS management increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring packet filtering rules and QoS rules in the network device before service data transmission. The P-GW or PCEF stores multiple rules with different priorities and matching criteria. When service data arrives, the device performs rule matching to automatically determine the appropriate QoS parameters and bearer processing actions, eliminating the need for complex real-time QoS negotiation and management during data transmission.
Solution Approach 2:
The patent implements feedback mechanisms where the network device monitors service data flow characteristics and compares them against configured rules. When a service flow matches a rule, the device triggers appropriate bearer processing actions and can update QoS parameters dynamically. This feedback loop allows the system to adapt to different service requirements while maintaining automated QoS management, reducing the complexity of manual configuration and management.
Data Source
AI summary
A bearer processing method and system, and a related apparatus. A GW-U is configured to receive a data packet and match the data packet with a rule, and send bearer processing indication information to a GW-C if a rule matching result of the data packet meets a trigger condition for bearer processing, where the bearer processing indication information is used to trigger the GW-C to perform bearer processing according to quality of service QoS information of a data service corresponding to the data packet. The GW-C is configured to receive the bearer processing indication information from the GW-U, determine, according to the bearer processing indication information, the QoS information of the data service corresponding to the data packet, and perform bearer processing according to the QoS information of the data service corresponding to the data packet.
