Dynamic Service Offloading via Network Controller Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service offloading methods in mobile communications fail to adapt to changes in the wireless environment, leading to low network utilization as one network may become overloaded while the other remains underutilized.
Innovation Solution
A method where user equipment sends attribute information and quality of service information to a network controller, allowing the controller to perform service offloading based on the received information and network status, and feedbacks an indication for selecting the appropriate bearer network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service offloading is performed using preset rules, then service quality can be ensured, but network utilization is low and cannot adapt to wireless environment changes
Solution Approach 1:
The patent implements dynamic service offloading by allowing the network controller to adjust offloading decisions in real-time based on current network conditions. The system transitions from static preset rules to dynamic adaptive control, where the network controller continuously monitors network status and adjusts service offloading policies accordingly, enabling the system to adapt to changing wireless environments while maintaining service quality.
Solution Approach 2:
The patent establishes a feedback mechanism where the network controller receives network status information and service quality metrics, processes this information, and adjusts service offloading decisions based on the feedback. This closed-loop control system enables continuous optimization of service offloading to match actual network conditions, resolving the contradiction between maintaining service quality and adapting to environment changes.
2Reliability
If service offloading is performed using preset rules, then service quality can be ensured, but network utilization is low causing excessive load on one network while the other remains underutilized
Solution Approach 1:
The system dynamically adjusts service offloading decisions based on real-time network load conditions. When one network becomes overloaded, the network controller dynamically shifts services to the other network, optimizing network utilization. This dynamic adjustment mechanism ensures both high service quality and efficient resource utilization across the network infrastructure.
Solution Approach 2:
The patent changes the parameter of service offloading from fixed preset values to dynamically adjustable parameters based on network status. The network controller monitors parameters such as network load, signal quality, and capacity, and adjusts offloading decisions by changing these parameters in real-time, thereby optimizing both service quality and network utilization simultaneously.

AI summary
The present application provides a service offloading method, a device, and a system, and relate to the mobile communications field. The method includes: sending attribute information of a first network to a network controller of a second network, where the attribute information includes identity information of the first network or a combination of identity information and status information of the first network; sending quality information of service to the network controller of the second network, receiving the service offloading indication fed back by the network controller; and selecting, according to the received service offloading indication, a bearer network for a service requested by user equipment, thereby achieving an effect that the network controller of the second network can perform service offloading appropriately according to a network status of the first network, the network status of the second network, and the quality information of service, so as to improve network utilization.
