Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP core network is unable to differentiate between MulteFire (MF) and LTE networks, hindering access restriction, handover, Quality of Service (QoS) control, and charging control for User Equipment (UE) in Neutral Host and Evolved Packet Core Network modes.
Innovation Solution
A network differentiation method and device that acquire and configure network attribute information to differentiate between MF and LTE networks based on unique Public Land Mobile Network (PLMN) IDs, radio access types, and service location areas, enabling access restriction, handover, QoS control, and charging control by managing subscriber server storage information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the 3GPP core network uses unified network architecture for both MF and LTE networks, then network compatibility and ease of operation are improved, but the ability to differentiate between network types is lost, preventing access restriction, handover, QoS control, and charging control
Solution Approach 1:
The patent introduces network type identification information at the local level (in the core network and RAN) to differentiate between MF and LTE networks. This allows the core network to recognize and handle different network types appropriately while maintaining the overall unified architecture, enabling access restriction, handover control, QoS management, and charging control specific to each network type.
Solution Approach 2:
The patent uses network type identification information as an intermediary element that bridges the unified core network architecture with the need for differentiated network handling. This identifier acts as a mediator that enables the core network to distinguish between MF and LTE networks without requiring separate core network architectures, thus resolving the contradiction between unity and differentiation.
2Device complexity
If the 3GPP core network adopts a unified architecture without network type identification, then device complexity and system complexity are reduced, but the precision of network control and measurement is deteriorated
Solution Approach 1:
The patent introduces network type identification information in advance at the core network and RAN levels, before any network control operations are performed. This preliminary identification enables subsequent precise control operations (access restriction, handover, QoS, charging) without requiring complex real-time differentiation mechanisms, thus maintaining low system complexity while achieving high control precision.
3Adaptability or versatility
If network type differentiation is implemented through separate core network architectures, then network differentiation capability is improved, but device complexity and system complexity increase significantly
Solution Approach 1:
The patent makes the unified core network architecture universal by introducing network type identification information that enables it to handle both MF and LTE networks appropriately. This single architecture performs multiple functions - it can differentiate between network types and apply appropriate control policies without requiring separate core network instances, thus achieving high adaptability while maintaining low complexity.
