Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mobile communication networks are inadequate to meet the demands of future 5G networks, particularly in terms of supporting high user density, flexible access types, and heterogeneous multi-layer coverage, due to limitations in mobility management, resource utilization, and security mechanisms.
Innovation Solution
A UE-centred network architecture is introduced, where access points (APs) act as intermediate nodes to monitor uplink signals, report information to local service centers, and provide radio signal channels, enabling flexible access modes and simplified mobility management, with local service centers acting as mobility anchors and network service centers managing service strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional LTE network architecture with centralized MME and SGW/PGW is used, then control plane functions are well-managed, but user plane flexibility and resource utilization are limited
Solution Approach 1:
The patent segments the traditional centralized network architecture into distributed network access nodes, each capable of independent control plane and user plane functions. This segmentation enables flexible access types ( wired/wireless, fixed/mobile) while distributing complexity across multiple nodes rather than concentrating it in centralized MME and gateway nodes.
Solution Approach 2:
The patent introduces dynamic resource allocation and flexible switching mechanisms that allow network access nodes to adapt their configuration based on real-time service requirements. The system can dynamically switch between different access modes and allocate resources flexibly, making the architecture adaptable without requiring complex static configurations.
2Quantity of substance
If network access node density is increased to support high user density, then service coverage is improved, but mobility management complexity and signaling overhead increase
Solution Approach 1:
The patent merges control plane and user plane functions into integrated network access nodes, eliminating the need for separate signaling paths to centralized MME for each access node. This consolidation reduces mobility management complexity by localizing control functions at each access node while maintaining high node density for improved service coverage.
Solution Approach 2:
The patent introduces a simplified intermediary mechanism where network access nodes directly communicate with each other and with user equipment without requiring complex centralized coordination for basic mobility management. This intermediary approach reduces signaling overhead while supporting high node density scenarios.
3Reliability
If user plane and control plane are strongly coupled, then signaling control is precise, but resource utilization efficiency and access flexibility decrease
Solution Approach 1:
The patent segments the coupled user plane and control plane into independently manageable components within each network access node. This segmentation allows precise signaling control to be maintained through dedicated control plane functions while resource utilization efficiency is improved by allowing user plane resources to be allocated and managed independently based on actual service demands.
Solution Approach 2:
The patent introduces dynamic coupling mechanisms where the strength of coupling between user plane and control plane can be adjusted based on service requirements. For signaling-intensive services, tighter coupling ensures precise control, while for data-intensive services, looser coupling improves resource utilization efficiency and access flexibility.
4Device complexity
If mobility anchor position is centralized at MME and PGW, then network control is simplified, but transmission latency and signaling overhead increase
Solution Approach 1:
The patent segments the centralized mobility anchor function into distributed mobility anchors at each network access node. This segmentation reduces transmission latency by localizing anchor functions closer to user equipment while maintaining control plane simplicity through standardized interfaces and protocols between distributed anchors.
Solution Approach 2:
The patent implements local mobility anchoring where each network access node maintains its own mobility anchor functionality tailored to local service requirements. This local quality approach reduces transmission latency for local traffic while maintaining simplified control through hierarchical management of local anchors.

AI summary
Disclosed are a mobile communication method, device and system, which are used for solving the problem where a traditional mobile communication network is unable to satisfy the requirements of a future 5G network. The system comprises: a user equipment (UE) for sending an uplink signal; at least one access point (AP) for monitoring the uplink signal sent by the UE adjacent thereto, obtaining first reporting information according to the uplink signal, and sending the first reporting information to a local service centre to which the access point belongs for processing; and the local service centre being used for processing the first reporting information.
