Access Network Device Data Offloading QoS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of service (QoS) cannot be ensured when data is offloaded using an unlicensed spectrum, a WLAN, or a secondary eNodeB due to dynamic nature of unlicensed spectrum and discontinuous deployment of WLAN and secondary eNodeB.
Innovation Solution
An access network device is provided with an indication receiving module to receive offloading inclination indications for service data, a resource allocation module to allocate transmission resources based on these indications, and a data transmission module to transmit data using the allocated resources, ensuring QoS by managing scheduling on LTE carriers, WLAN, or secondary eNodeB resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data offloading is implemented using unlicensed spectrum, WLAN, or secondary eNodeB to increase transmission capacity, then productivity is improved, but reliability deteriorates because QoS cannot be ensured due to dynamic nature of unlicensed spectrum and discontinuous deployment
Solution Approach 1:
The patent implements dynamic resource allocation where the network device adjusts transmission parameters in real-time based on channel conditions and QoS requirements. The system dynamically selects between licensed and unlicensed resources, modifies transmission power and bandwidth allocation, and adapts modulation schemes to maintain QoS while utilizing available offloading resources effectively
Solution Approach 2:
The patent changes multiple transmission parameters including power allocation, bandwidth distribution, modulation order, and coding rate to optimize QoS on unlicensed resources. The system adjusts these parameters based on channel quality indicators, interference levels, and service type requirements to ensure reliable transmission over dynamic unlicensed spectrum
2Productivity
If unlicensed spectrum resources are used for data offloading to increase transmission capacity, then productivity is improved, but stability deteriorates due to dynamic availability of unlicensed spectrum
Solution Approach 1:
The patent performs preliminary actions by pre-configuring multiple transmission paths including both licensed and unlicensed resources before actual data transmission. The system pre-establishes resource pools, configures fallback mechanisms, and prepares alternative routing options to ensure continuous service when unlicensed resources become unavailable
Solution Approach 2:
The patent introduces an intermediary layer that manages resource selection between licensed and unlicensed spectrum. This intermediary component monitors resource availability, makes intelligent routing decisions, and seamlessly switches between resource types to maintain stable transmission despite fluctuations in unlicensed spectrum availability
3Productivity
If WLAN and secondary eNodeB are deployed to provide additional transmission resources for offloading, then productivity is improved, but reliability deteriorates due to discontinuous deployment
Solution Approach 1:
The patent creates a universal resource management framework that handles multiple transmission resource types (licensed spectrum, unlicensed spectrum, WLAN, secondary eNodeB) through a single unified control mechanism. The system applies consistent QoS policies across all resource types and provides uniform service abstraction, making the discontinuous deployment of specific resources less impactful on overall reliability

AI summary
Embodiments of the present invention provide a core network device, an access network device, and a data offloading method and system, and relate to the field of mobile communications. In the system, the access network device receives an offloading inclination indication of service data from the core network device; the access network device allocates, according to the offloading inclination indication, a transmission resource used for transmitting the service data; and the access network device transmits the service data by using the allocated transmission resource. In the present invention, a problem is resolved that QoS in a transmission process cannot be ensured when data is offloaded by using a first resource such as an unlicensed spectrum, a transmission resource provided by a WLAN, or a transmission resource provided by a secondary eNodeB, and the QoS in the transmission process can be ensured even if the data is offloaded by using the first resource such as the unlicensed spectrum, the transmission resource provided by the WLAN, or the transmission resource provided by the secondary eNodeB.
