Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems struggle to optimize data routes according to differentiated bandwidth and low latency requirements due to their architecture not being designed for various application services, leading to limitations in optimizing data transmission in the user plane.
Innovation Solution
Implement session management based on Segment Routing IPv6 (SRv6) to simplify the protocol stack and enable differentiated routes for user services, with the method and device determining uplink and downlink SR routes and supporting SRv6 in base stations to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If session management is performed using traditional mobile communication system architecture, then the system maintains stability and compatibility, but the protocol stack becomes complex and data route optimization is limited
Solution Approach 1:
The patent extracts the session management function from the traditional mobile communication architecture and implements it independently using SRv6 technology. By separating the session management entity and using SRv6 for route determination, the complex traditional protocol stack is simplified while gaining the ability to optimize data routes according to service requirements
Solution Approach 2:
The patent changes the routing parameters from traditional fixed tunneling parameters to SRv6-based flexible parameters. By using SR policies and segment routing headers, the system can dynamically adjust route parameters based on service requirements, enabling differentiated data transmission paths
2Adaptability or versatility
If the mobile network architecture is designed for general purposes, then the system maintains broad compatibility, but it cannot rapidly respond to differentiated bandwidth and low latency requirements
Solution Approach 1:
The patent segments the user plane into multiple independent data transmission paths with different SR policies. Each service type can be assigned to specific segments with optimized routes, enabling the system to respond to differentiated bandwidth and latency requirements without redesigning the entire architecture
Solution Approach 2:
The patent creates a universal session management framework based on SRv6 that can handle multiple service types simultaneously. The same SRv6 infrastructure supports diverse services including enhanced mobile broadband, ultra-reliable low latency communication, and massive machine type communication through policy-based route differentiation

AI summary
A network function performs session management in a mobile communication system. The network function includes a memory configured to store at least one program, a transceiver unit configured to transmit and receive at least one signal, and a processor configured to execute at least one program stored in the memory, wherein the processor performs session establishment based on a terminal request, allocates at least one uplink tunnel endpoint ID (TEID) and at least one downlink TEID based on the session establishment, determines an uplink segment routing (SR) route and a downlink SR route based on segment routing IPV6 (SRv6), and performs SR route setup for at least one network function based on the determined uplink SR route and the determined downlink SR route.
