Location Management Server for Flexible Base Station Gateway Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with base stations and access gateways configured in an IP mesh network, users lack flexibility in combining base stations and access gateways, leading to inefficient network management and the need for access gateways to support all services, resulting in suboptimal network utilization.
Innovation Solution
A communication system and operation control method that includes a location management server which designates an access gateway for a mobile station based on location registration requests, allowing for flexible combination of base stations and access gateways, and enabling efficient network management by utilizing databases to determine the most appropriate access gateway for each mobile station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If base stations select access gateways using fixed logic (e.g., based on IMSI bit array), then the system maintains simple operation, but network flexibility and efficient resource utilization deteriorate
Solution Approach 1:
The patent introduces a location management server as an intermediary between base stations and access gateways. This server receives location registration requests from base stations, determines the most appropriate access gateway based on multiple factors (service types, gateway capabilities, current load status), and returns the selected gateway information. This mediator resolves the contradiction by centralizing the complex selection logic, keeping base station operations simple while enabling flexible, optimized gateway assignment.
2Adaptability or versatility
If access gateways support all services provided by portable telephone carrier networks, then service coverage is complete, but device complexity and resource utilization efficiency deteriorate
Solution Approach 1:
The patent segments the network into different functional components: base stations handle radio access, the location management server handles intelligent routing and service matching, and access gateways handle specific service types. This segmentation allows gateways to be specialized for particular services rather than supporting all services, reducing individual gateway complexity while maintaining overall service coverage through the coordinated network.
Solution Approach 2:
The location management server provides multi-functionality by handling multiple tasks: receiving location registration requests, determining user service requirements, selecting appropriate access gateways, and managing mobile station location information. This universal server consolidates the complexity that would otherwise be distributed across all gateways, enabling gateways to remain simpler while the system as a whole maintains full service coverage.
3Stability of the object's composition
If mobile stations continue to use initially registered access gateways, then connection stability is maintained, but network resource utilization and service optimization deteriorate
Solution Approach 1:
The patent implements dynamic access gateway selection through the location management server. When mobile stations perform location registration, the server dynamically determines the most appropriate gateway based on current network conditions, service requirements, and gateway status. This dynamic approach allows the system to adapt to changing conditions while maintaining stable connections through the formal location registration process, resolving the contradiction between stability and efficiency.
Data Source
AI summary
A method for a base station includes receiving a signal relating to a location of a user equipment (UE) from the UE, selecting a first exchange for the UE and sending the signal to the first exchange, and sending the signal to a second exchange based on subscription information of the UE provided by a server.
