Multi-Access PDU Aggregation Using Core Network Offload Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Challenges exist in implementing and managing data aggregation across 3GPP and non-integrated IP networks in next-generation wireless communication systems, such as 5GS, for user equipment (UE) access to core networks.
Innovation Solution
A UE communicates with a core network over a 3GPP network, requests a protocol data unit (PDU) session for data aggregation, receives a response with an offload percentage, and transmits data to both the 3GPP and non-integrated IP networks based on this percentage.

Engineering Contradiction Analysis
1Productivity
If data aggregation is implemented across 3GPP and non-integrated IP networks, then network resource utilization and data transmission efficiency are improved, but system complexity and management difficulty increase
Solution Approach 1:
The patent introduces a network aggregation entity as an intermediary component that manages and coordinates data transmission across multiple access networks (3GPP and non-integrated IP networks). This mediator handles the complexity of multi-network aggregation centrally, allowing UEs to benefit from improved data transmission efficiency without each device needing to implement complex aggregation logic locally.
Solution Approach 2:
The system segments the data aggregation functionality into distinct components: the network aggregation entity manages the aggregation logic and coordination, while UEs focus on data transmission. This segmentation allows the complex aggregation management to be handled by a dedicated network entity rather than being distributed across all devices, reducing overall system complexity while maintaining high productivity.
2Reliability
If multiple access networks are used for data transfers, then network capacity and reliability are improved, but implementation and management challenges increase
Solution Approach 1:
The network aggregation entity serves as a mediator that simplifies the management of multiple access networks. It handles the complexity of coordinating between 3GPP and non-integrated IP networks centrally, making the system easier to manage and operate while maintaining the reliability benefits of multi-network connectivity.
Solution Approach 2:
The network aggregation entity provides universal management capabilities across different network types (3GPP and non-integrated IP networks). This multi-functional entity can handle various network protocols and configurations through a unified interface, improving ease of operation while maintaining reliable connections across multiple access networks.
3Productivity
If data is transmitted across both 3GPP and non-integrated IP networks, then network resource optimization is achieved, but coordination complexity increases
Solution Approach 1:
The network aggregation entity acts as an intermediary that optimizes data transmission across 3GPP and non-integrated IP networks by centrally managing resource allocation and coordination. This approach achieves improved network resource utilization while concentrating the coordination complexity in a single network entity rather than distributing it across multiple devices.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as offload percentages and routing decisions based on network conditions. The network aggregation entity modifies these parameters in real-time to optimize resource utilization across different networks, achieving high productivity while managing coordination complexity through centralized parameter control.

AI summary
Aspects relate to multiple access networks with non-integrated aggregation. In one aspect, a UE may communicate with a core network over a 3rd Generation Partnership Project (3GPP) network, transmit a request to the core network for a protocol data unit (PDU) session comprising a request for data aggregation across the 3GPP network and a non-integrated internet protocol (IP) network, and receive a response from the core network granting the requested PDU session, the response including identification of a core network aggregation entity and an offload percentage. The UE may also transmit data to the core network aggregation entity via the non-integrated IP network based on the offload percentage, and transmit data to the core network aggregation entity via the 3GPP network based on the offload percentage.
