Solution Overview

Problem

In conventional GPON systems, the quality of service (QoS) characteristics of service flows in 5G customized services are not considered during upstream transmission, leading to inconsistent scheduling with 5G networks, resulting in delayed service flow scheduling.

Innovation Solution

A data transmission method that maps service flows in a fixed-mobile convergence network to virtual connections and bearer queues based on their quality of service identifiers, ensuring scheduling consistency with mobile networks, and prioritizing higher-priority service flows.

1Ease of operation

If conventional GPON upstream transmission is used without QoS consideration, then device complexity is reduced and ease of operation is improved, but service flow scheduling is delayed and reliability deteriorates

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent segments the service flow scheduling process into distinct mapping stages: service flow identification, virtual connection mapping, virtual bearer mapping, and virtual bearer queue mapping. Each stage handles specific QoS parameters independently, allowing complex QoS scheduling to be broken down into manageable operations that maintain reliability without overwhelming system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary mapping actions by pre-establishing mapping relationships between service flows, virtual connections, virtual bearers, and virtual bearer queues before actual data transmission. This preliminary configuration ensures that QoS scheduling decisions can be made quickly during transmission without real-time computation delays, improving both reliability and operational efficiency

Inventive Principle:

2Reliability

If QoS-based mapping is implemented in fixed-mobile convergence network, then service flow scheduling reliability is improved and scheduling delay is reduced, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal mapping framework that handles multiple service flow types and QoS requirements through a single set of mapping principles. The virtual connection, virtual bearer, and virtual bearer queue structures serve multiple functions: they identify service flows, prioritize transmissions, and manage resources simultaneously. This multi-functionality reduces the need for separate complex mechanisms for each QoS requirement

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements a nested mapping structure where service flows are mapped to virtual connections, which are then mapped to virtual bearers, which in turn are mapped to virtual bearer queues. This hierarchical nesting organizes complex QoS management into layered relationships, where each layer manages a specific aspect of the mapping, reducing overall system complexity while maintaining comprehensive QoS control

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

This application provides a data transmission method and apparatus, a gateway, a chip, and a storage medium. The method includes: mapping a to-be-transmitted service flow to a virtual connection based on a mapping relationship between an identifier of the to-be-transmitted service flow in a mobile network and an identifier of the virtual connection; mapping the to-be-transmitted service flow to a virtual bearer based on a mapping relationship between the identifier of the virtual connection and an identifier of the virtual bearer; and mapping the to-be-transmitted service flow to a virtual bearer queue based on a mapping relationship between a quality of service characteristic identifier of the to-be-transmitted service flow and an identifier of the virtual bearer queue in the virtual bearer, to transmit the to-be-transmitted service flow to an optical line terminal. In other words, when the service flow is scheduled, scheduling is performed based on the quality of service characteristic identifier of the to-be-transmitted service flow, which is consistent with a scheduling manner in the mobile network. Therefore, scheduling of the to-be-transmitted service flow is not delayed.
