MTC Gateway Data Path Control via ANDSF Policy Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to effectively manage and control data paths in Machine-type-communication (MTC) networks, particularly in scenarios where MTC service providers and mobile network operators are separate entities, leading to challenges in populating routing tables and updating policies across interconnected MTC gateways, which affects service quality and revenue.
Innovation Solution
A network device equipped with an Access Network Discovery and Selection Function (ANDSF) that receives capillary network and MTC gateway interconnection information from an MTC server, generates enhanced policy rules, and transmits these rules to interconnected MTC gateways, enabling dynamic control of data flows and routing tables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MTC gateways are interconnected to improve service quality and provide backup routing, then system reliability is improved, but routing table population and policy control complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the MTC server acts as a mediator to provide gateway interconnection information to the ANDSF. This allows the ANDSF to obtain routing information without direct complex interactions with multiple MTC gateways, simplifying the routing table population process while maintaining the reliability benefits of interconnected gateways.
Solution Approach 2:
The patent implements preliminary action by having the MTC server pre-provision gateway interconnection information and making it available to the ANDSF before routing decisions need to be made. This advance preparation eliminates the need for real-time complex queries to multiple gateways, reducing operational complexity while maintaining service reliability.
2Reliability
If dynamic policy control is implemented to optimize data flows, then service quality is improved, but information sharing requirements between MTC service provider and MNO increase
Solution Approach 1:
The MTC server serves as an intermediary that collects information from the MTC service provider domain and translates it into a format suitable for the MNO's ANDSF. This intermediary layer enables dynamic policy control without requiring direct information sharing between the service provider and operator, reducing information loss and privacy concerns.
Solution Approach 2:
The patent implements feedback mechanisms where the ANDSF receives gateway interconnection information from the MTC server, processes it to generate enhanced policy rules, and sends these rules back to the MTC gateways. This feedback loop enables continuous optimization of data flows while maintaining clear information boundaries between different organizational domains.
3Adaptability or versatility
If ANDSF obtains gateway interconnection information from MTC server, then routing control capability is improved, but system complexity increases
Solution Approach 1:
By introducing the MTC server as an intermediary information source, the ANDSF gains enhanced routing control capability without directly managing complex gateway interconnection logic. The server handles the complexity of collecting and formatting gateway information, allowing the ANDSF to focus on policy generation and distribution.
Solution Approach 2:
The patent segments the system into distinct functional components: the MTC server handles service provider domain information, the ANDSF handles policy generation, and the MTC gateways handle execution. This segmentation allows each component to be optimized independently, improving overall routing control capability while managing system complexity through clear functional boundaries.
