Radio Network Sharing via TMSI-Based Operator Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio network sharing methods fail to effectively share channel and frequency resources between operators, leading to waste of network device resources, as they are based on independent cell identities and do not allow for the sharing of existing network device resources.
Innovation Solution
A method that involves obtaining a temporary mobile subscriber identity, extracting a network resource identifier, and using a preset mapping relationship to route service signaling to the corresponding core network, allowing different operators to share cells and resources without modifying existing network devices, thereby enabling the sharing of frequency and channel resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network sharing is implemented based on cell ID with independent cells for different operators, then operators can maintain their own network independence, but channel resources and frequency resources cannot be shared leading to waste of network device resources
Solution Approach 1:
The patent merges multiple operators' cell resources into shared cells. The base station controller pools channel resources and frequency resources from multiple operators into common resource pools, allowing simultaneous access by different operators' mobile terminals. This combining of previously separate resources enables both network sharing and resource efficiency.
Solution Approach 2:
The patent creates universal resource pools that serve multiple operators simultaneously. The base station controller's channel resources and frequency resources become multi-functional, serving different operators' needs through a unified resource management system. Mobile terminals from different operators can access the same pooled resources, achieving universality in resource utilization.
2Quantity of substance
If operators share physical devices such as base station controller and base transceiver station, then capital expenditure can be reduced, but existing network device resources cannot be fully utilized due to independent cell operations
Solution Approach 1:
The patent combines physical devices from multiple operators into shared infrastructure. Base station controllers and base transceiver stations are physically shared while logically managing resources through pooling. This merging reduces the total quantity of physical devices needed while improving their utilization through coordinated resource management across operators.
Solution Approach 2:
The patent introduces dynamic resource allocation in shared physical devices. The base station controller dynamically assigns channel resources and frequency resources from pooled resources to different operators' mobile terminals based on current demand. This dynamic management enables existing physical devices to serve multiple purposes efficiently, improving productivity without additional hardware.
3Ease of operation
If different operators use their respective different cells, then each operator maintains separate network control, but radio spectrum resources and power resources cannot be shared between core networks
Solution Approach 1:
The patent segments resource management from cell management. While cells are shared physically, the system segments resource allocation by creating operator-specific logical partitions within the shared cell structure. The base station controller segments channel and frequency resources into operator-specific pools, allowing independent control for each operator while sharing the physical infrastructure and radio spectrum resources.
Solution Approach 2:
The base station controller acts as an intermediary between multiple operators and shared radio spectrum resources. It mediates resource allocation by pooling channel resources and frequency resources, then distributing them to different operators' mobile terminals according to demand. This intermediary function enables radio spectrum and power resource sharing while maintaining ease of operation through centralized coordination.
