Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions lack effective methods for implementing Quality of Service (QoS) control when a 5G core network is accessed through a fixed network, which is essential for ensuring optimal data packet forwarding and policy management.
Innovation Solution
A QoS control method and system that includes an access gateway function entity and a session management function entity, which obtain and communicate the correspondence between QoS files and VLAN priorities, enabling QoS control on uplink data packets by setting appropriate VLAN priorities, thereby ensuring QoS control when a 5G core network or future networks are accessed through fixed networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoS control is implemented when accessing 5G core network through fixed network, then network performance and reliability are improved, but device complexity and implementation difficulty increase due to lack of existing solutions
Solution Approach 1:
The access gateway function entity is designed to perform multiple functions including QoS control, data packet forwarding, and policy management within a single entity, enabling it to handle both 5G mobile access and fixed network access scenarios universally. This multi-functionality allows the system to implement QoS control across different access types without requiring separate specialized systems.
Solution Approach 2:
The access gateway function entity acts as an intermediary between the fixed network and the 5G core network, translating and adapting QoS parameters and policies between these different network domains. It mediates the interaction by establishing correspondence between QoS files and VLAN priorities, enabling seamless QoS control across the hybrid access architecture.
2Manufacturing precision
If QoS control policies are enforced on uplink data packets, then data packet management quality is improved, but processing time and operational complexity increase
Solution Approach 1:
QoS control policies and parameter correspondences are pre-configured and established in the access gateway function entity before actual data packet transmission occurs. The entity obtains and stores the correspondence between QoS files and VLAN priorities in advance, so that when uplink data packets arrive, the entity can quickly match them against pre-established policies without performing complex real-time analysis.
Solution Approach 2:
The QoS control process is segmented into distinct functional stages: policy definition, parameter correspondence establishment, packet classification, and enforcement. By dividing the complex QoS management into these manageable segments, the system can process each aspect efficiently and independently, reducing overall processing time while maintaining high precision in data packet management.

AI summary
This application discloses a QoS control method, device, and system, to implement QoS control when a 5G core network or another future network is accessed through a fixed network. The method includes: obtaining, by an access gateway function entity, a correspondence between a QoS file and a virtual local area network VLAN priority, where the correspondence between the QoS file and the VLAN priority includes a correspondence between a first QoS file and a first VLAN priority; sending, by the access gateway function entity, a first message to a terminal, where the first message includes the correspondence between the QoS file and the VLAN priority; receiving, by the access gateway function entity, an uplink data packet from the terminal, where a QoS file corresponding to the uplink data packet is the first QoS file, and the uplink data packet carries the first VLAN priority; and performing, by the access gateway function entity, QoS control on the uplink data packet based on the first VLAN priority.
