Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing access combinations for multiple access protocol data unit (PDU) sessions across different types of access technologies, leading to undefined behavior and suboptimal energy management in communication devices.
Innovation Solution
A communication device receives control signaling indicating configuration rules for multiple access sessions involving multiple access links of different types, such as 3GPP and non-3GPP access, and selects an appropriate mode for data flow allocation and transmission, enabling efficient management of access combinations to enhance energy saving and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access links of different types are used for PDU sessions, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The patent segments access session management by introducing distinct control mechanisms for different access link types (3GPP and non-3GPP). Each access link type is managed through separate configuration parameters and control signaling procedures, allowing independent optimization and simplifying the overall management complexity while maintaining multi-access capability.
Solution Approach 2:
The patent implements universal access session management functionality that can handle multiple access link types through a unified framework. The system provides multi-functional capabilities to manage both 3GPP and non-3GPP access links simultaneously, using common control plane procedures and configuration mechanisms that adapt to different access types, thereby reducing overall system complexity.
2Use of energy by moving object
If access combinations are not properly managed, then device complexity is reduced, but energy efficiency deteriorates
Solution Approach 1:
The patent implements dynamic access combination management where the system can adaptively adjust which access links are active based on current conditions. The UE can dynamically switch between different access link combinations and activate/deactivate specific access links as needed, optimizing energy consumption by keeping only necessary access links active while maintaining the capability to use multiple accesses when required.
Solution Approach 2:
The patent utilizes parameter changes in control signaling to manage access combinations efficiently. Configuration parameters indicate which access link types are available and how they should be combined, allowing the system to optimize energy usage by changing operational parameters based on current network conditions and service requirements without increasing fundamental system complexity.

AI summary
Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.
