NetLMM Domain Managing Device for Simultaneous Multi-Interface Mobile Node Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems in NetLMM domains cannot enable simultaneous connection of multiple interfaces of a mobile node, leading to limitations in network flexibility and efficiency, particularly when a mobile node tries to connect with multiple access gateways using different interfaces.
Innovation Solution
A communication system with a domain managing device that maintains association information for mobile terminals, allowing simultaneous connections by checking and updating association information across multiple edge devices and managing packet transfer paths, enabling multiple interfaces to connect simultaneously within a NetLMM domain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile node connects with multiple access gateways using different interfaces, then network flexibility and efficiency are improved, but the system cannot currently enable simultaneous connection of multiple interfaces in NetLMM domains
Solution Approach 1:
The patent segments the connection management by introducing separate association information records for each interface-edge device connection. Each interface's connection state is independently tracked through distinct association information, allowing multiple interfaces to be managed simultaneously without conflict. This segmentation enables the mobile node to maintain multiple active connections while the domain managing device can individually control and monitor each connection.
2Productivity
If association information is maintained for each mobile terminal connection, then simultaneous connections can be enabled, but the domain managing device must check and update association information across multiple edge devices
Solution Approach 1:
The patent implements a feedback mechanism where the domain managing device actively monitors and checks association information across multiple edge devices. When a mobile node attempts to connect through a new edge device, the domain managing device queries existing association information to determine whether to permit the connection. This feedback loop ensures consistent connection state management while enabling simultaneous connections through coordinated information updates across the network infrastructure.

AI summary
A technique disclosed enables a node having a plurality of interfaces to conduct connection of the plurality of interfaces simultaneously in a communication network domain. A mobile node having a plurality of interfaces connects one of the interfaces with a MAG (mobile access gateway) 11a to take part in a NetLMM domain 18 using a NetLMM protocol, and a LMA (local mobility anchor) 13 includes association information with the MAG 11a registered therein. When the mobile node connects another interface with another MAG 11 b, the LMA receives a registration request for association information of this mobile node with the MAG 11 b, and makes an inquiry to the already registered MAG 11a as to whether link with the mobile node is still valid or not. If the link is valid, the LMA keeps association information of the mobile node with both of the MAGs 11 a and 11 b.
