Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G communication systems face challenges in managing packet data unit (PDU) sessions due to the diversification of data services and electronic devices, with electronic devices unable to autonomously control PDU sessions without manual user intervention, leading to inefficient resource management.
Innovation Solution
An electronic device is equipped with modules to detect events, monitor network status, and control PDU sessions based on application information, network configuration, and use history, enabling autonomous PDU session establishment, release, and modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electronic device establishes PDU sessions with preconfigured APN or DNN values during bootup and releases sessions based on network situation, then the device can maintain basic connectivity, but the device cannot autonomously control PDU session establishment to new APN or DNN without manual user operation
Solution Approach 1:
The electronic device autonomously manages PDU sessions by detecting application information and automatically establishing sessions with appropriate APN/DNN values without requiring manual user operation. The device monitors network status and application requirements, then self-initiates session establishment, modification, or release based on detected conditions, enabling true autonomous control of PDU sessions
Solution Approach 2:
The device continuously monitors network status and application information, using this feedback to dynamically adjust PDU session establishment decisions. By detecting changes in network conditions and application requirements, the system adapts its session management behavior accordingly, enabling intelligent autonomous control rather than static preconfigured behavior
2Adaptability or versatility
If the electronic device establishes multiple PDU sessions for diversified data services and applications, then the device can support various services simultaneously, but the resource management becomes inefficient without autonomous control
Solution Approach 1:
The system segments PDU session management by application, creating dedicated sessions for different applications with their specific APN/DNN requirements. This allows diversified services to run simultaneously in isolated sessions while enabling granular control over each session's resource allocation, resolving the conflict between service diversity and resource efficiency
Solution Approach 2:
The system dynamically establishes, modifies, or releases PDU sessions based on real-time detection of application information and network status. Rather than maintaining static sessions, the system adapts session configuration to current service requirements and network conditions, optimizing resource utilization while supporting diverse services
3Ease of operation
If manual user operation is required to establish PDU session to new APN or DNN, then the device can ensure user awareness and control, but the device cannot autonomously control PDU session establishment
Solution Approach 1:
The system performs preliminary detection of application information and pre-establishes PDU sessions with appropriate APN/DNN values before user requests are needed. By proactively configuring sessions based on detected application requirements, the system eliminates manual user operation and reduces establishment time while maintaining user awareness through transparent automatic management

AI summary
An electronic device includes a memory, a communication module, and a processor configured to identify an application identifier of an application stored in the memory, receive information on a network status through the communication module, identify an available PDU based on an allowed network slice included in the information on the network status, determine whether it is possible to establish a PDU session among the available PDU, based on the identified application identifier and the allowed network slice, and establish the PDU session based on a result of the determination. Further, a corresponding method performed by the electronic devices is provided.
