Solution Overview

Problem

Current cellular mobile communication systems are inefficient and costly when handling large-traffic low-speed IP data packet services indoors and in hotspot areas, with traditional solutions like WLAN and LTE Femto systems either failing to provide telecommunication-level QoS or being overly complex and expensive.

Innovation Solution

A novel radio network access system and QoS mechanism that determines QoS levels for downlink and uplink service data packets at the MAC layer based on IP layer attribute information, allowing for scheduled radio resource transmission without requiring core network participation, thus optimizing indoor and hotspot data services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If WLAN system is used for indoor and hotspot data services, then deployment cost and complexity are reduced, but QoS guarantee capability is lost and link quality becomes susceptible to interference

Engineering Contradiction:
Improvedeployment complexityVSAvoidQoS guarantee capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the QoS control function from the core network and places it at the access network level (eNodeB). This allows WLAN-like deployment simplicity while maintaining telecommunication-level QoS guarantees through dedicated QoS control entities at the base station, resolving the contradiction between deployment ease and QoS reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a QoS control entity as an intermediary between the core network and the radio access network. This intermediary handles QoS policy enforcement and resource allocation locally at the eNodeB, providing QoS guarantees without requiring complex core network involvement for each service, thus balancing deployment simplicity with QoS reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If LTE Femto system is used for indoor data services, then QoS guarantee capability is maintained, but system complexity and deployment cost increase significantly

Engineering Contradiction:
ImproveQoS guarantee capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the QoS control functionality from the complex LTE Femto system architecture and consolidates it into a dedicated QoS control entity at the eNodeB. This extraction maintains QoS guarantee capabilities while simplifying the overall system architecture by removing the need for complex core network QoS processing and multiple protocol layers required in traditional Femto systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The QoS control entity at the eNodeB serves multiple functions including policy enforcement, resource allocation, and service quality monitoring. This multi-functional design maintains QoS guarantees while reducing system complexity by consolidating what would otherwise require separate complex subsystems in the LTE Femto architecture.

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

3Reliability

If traditional cellular mobile communication system is used for indoor data services, then QoS guarantee is maintained, but efficiency and cost effectiveness deteriorate due to high overhead for low-mobility services

Engineering Contradiction:
ImproveQoS guaranteeVSAvoidservice efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by implementing QoS control specifically tailored for indoor and hotspot scenarios at the access network level. The QoS control entity at the eNodeB provides telecommunication-level QoS guarantees optimized for low-mobility data services without imposing the full overhead of traditional cellular systems, thereby improving service efficiency while maintaining QoS reliability.

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed are a scheduling method, device and system based on quality of service. The method includes: for downlink service data, an access point (AP) or a gateway (GW) determines the quality of service (QoS) level of a downlink service packet of a media access control (MAC) layer according to the QoS attribute information of the downlink service packet of the IP layer, and then the AP transmits and schedules radio resources according to the QoS level; for uplink service data, user equipment (UE) determines the QoS level of an uplink service packet of the MAC layer according to the QoS attribute information of the uplink service packet of the IP layer, and reports the QoS level and the other QoS parameters to the AP in the manner of a scheduling request, and the AP completes the transmitting and scheduling of radio resources according to the QoS level, so that the UE transmits the uplink service data to the AP. Aimed at low-cost hot spot and indoor data service access, the present invention provides a novel network architecture and a perfect QoS service mechanism.
