Local Access Gateway Selection via DNS Inquiry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to effectively select a local access gateway, making it impossible to properly implement local access functions in mobile communication networks, which hampers the reduction of core network load and user experience.
Innovation Solution
A method and system that utilize a Domain Name System (DNS) server to construct and inquire local access gateway information based on Access Point Name (APN), base station identity, Closed Subscriber Group (CSG), location identifier, and tracking area/routing area identity, allowing the mobile management unit to select an appropriate local access gateway for establishing local connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If local access gateway selection is not implemented, then the system structure remains simple, but local access functions cannot be properly implemented and core network load cannot be reduced
Solution Approach 1:
The patent introduces a DNS server as an intermediary component to resolve domain names to IP addresses of local access gateways. The mobile management unit queries the DNS server with a domain name, and the DNS server returns the corresponding gateway IP address. This intermediary mechanism enables gateway selection without adding complex selection logic to existing network elements, thus implementing local access functions while maintaining system simplicity.
2Loss of energy
If local access gateway is used, then core network load is reduced, but the ability to select appropriate gateway is lacking
Solution Approach 1:
The patent implements a feedback mechanism where the mobile management unit queries the DNS server to obtain gateway information based on domain name resolution. The DNS server maintains mapping relationships between domain names and gateway IP addresses, providing feedback information that enables the mobile management unit to select the appropriate local access gateway. This feedback loop ensures that traffic can be directed to local gateways when available, reducing core network load while maintaining adaptability through domain-based gateway selection.
Data Source
AI summary
The disclosure discloses a method for implementing local access, which includes: after user terminal initiates a local access and a mobile management unit determines that the local connection can be established for the user terminal, the mobile management unit acquires local access gateway information through a Domain Name System (DNS) server. The disclosure further discloses a system for implementing local access, correspondingly. By providing a specific implementation solution of inquiring the local access gateway, the disclosure ensures selection between the core network gateway and the local access gateway according to a respective scenario, thus properly and effectively implementing the local access function implemented by the user terminal through the local access gateway.
