Dynamic PDN Connection Management for QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network performance in mobile terminals is inadequate for providing high-quality, on-demand services, especially in user-intensive areas, due to resource constraints and the need for flexible QoS guarantees for applications sensitive to latency and bandwidth, such as real-time games and video broadcasts.
Innovation Solution
User equipment establishes multiple PDN connections based on application requirements, allowing different applications to use remote IP networks through distinct PDN connections, optimizing network resource allocation and enhancing service experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated bearer is set up from the network side to ensure bandwidth and latency, then QoS guarantee is improved, but radio resource consumption increases excessively
Solution Approach 1:
The patent implements dynamic bearer management where the terminal device requests establishment of dedicated bearers only when applications with specific QoS requirements are detected, and releases them when no longer needed. This transforms the static network configuration into a dynamic system that adapts to real-time application needs, reducing radio resource consumption while maintaining QoS guarantees when required.
Solution Approach 2:
The system changes network parameters (bearer establishment, QoS parameter configuration) based on application requirements. When an application requiring guaranteed bandwidth or low latency is detected, the terminal requests specific QoS parameters and dedicated bearer establishment. When such applications are not running, these parameters are released, allowing the network to reallocate resources efficiently.
2Adaptability or versatility
If differentiated network services are provided for different applications, then user experience is improved, but network device complexity increases
Solution Approach 1:
The terminal device performs self-service by autonomously detecting application types, determining QoS requirements, and requesting appropriate bearer configurations without requiring complex network-side analysis. The network device simply responds to terminal requests, significantly reducing network device complexity while still providing differentiated services based on application needs.
Solution Approach 2:
The patent segments network services into different bearer types (default bearer and dedicated bearers with specific QoS parameters) based on application requirements. This segmentation allows the network to provide differentiated services for various application types (e.g., real-time gaming, video streaming, file download) while keeping the overall system architecture simple and manageable.

AI summary
The present disclosure relates to a network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection, and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program, and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection. According to the solutions provided in this application, a new PDN connection can be flexibly and dynamically established based on an application service requirement of user equipment and a network status, and application data is transmitted through the new PDN connection, improving network performance of the user equipment application.
