Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3GPP tunnel-based and bearer-based connection-oriented architectures in wireline and wireless networks face scalability challenges due to high signaling overhead, particularly with the increasing number of end-user devices like XR, smart devices, and IoT devices.
Innovation Solution
A connectionless architecture utilizing the Relativistic Routing Protocol (RRP) for dual-connectivity mobility in 5G and beyond networks, which minimizes latency and enhances network efficiency by not maintaining connection states and using a distributed graph for optimal packet delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection-oriented architectures (tunnel-based and bearer-based) are used in wireless networks, then network reliability and connection management are improved, but signaling overhead increases and scalability deteriorates
Solution Approach 1:
The patent extracts the connection state maintenance function from the core network and relocates it to the edge network elements (gNBs and UPFs). This removes the signaling overhead burden from the core network while maintaining connection reliability at the edge, directly resolving the contradiction between connection management and signaling overhead
Solution Approach 2:
The patent segments the network into access network (gNB), transport network, and core network (5GC) components, with each having distinct responsibilities. The access network handles connection management locally without requiring core network involvement for mobility events, reducing signaling overhead while maintaining reliability through distributed intelligence
2Stability of the object's composition
If connection-oriented architectures are used for mobility management, then connection stability is improved, but network scalability and cost-effectiveness worsen due to tunnel setup/tear down overhead
Solution Approach 1:
The patent establishes connection state information in advance at edge network elements before mobility events occur. When mobility happens, the pre-configured connection states enable seamless handover without requiring tunnel setup/tear down, maintaining connection stability while enabling network scalability
Solution Approach 2:
Instead of the core network managing connections centrally (traditional approach), the patent inverts the architecture so that edge network elements manage connections autonomously. This inversion eliminates the scalability bottleneck while maintaining connection stability through distributed connection management
3Device complexity
If traditional wireline and wireless networks are siloed with separate architectures, then network control and management are simplified, but integration capability and overall network efficiency deteriorate
Solution Approach 1:
The patent implements a unified transport network architecture that serves both wireline and wireless access networks with common protocols and mechanisms. This universal architecture enables seamless integration between different access types while maintaining manageable complexity through standardized interfaces and procedures
Solution Approach 2:
The patent merges previously siloed wireline and wireless network architectures into a single integrated transport network. By combining the control and management planes while maintaining separate data planes where needed, the system achieves integration capability without excessive complexity through careful architectural design
