Domain Manager Channel Registration for Mobile Node Management
Solution Overview
Problem
Current self-organized network (SON) operational and maintenance (OAM) architectures face challenges in efficiently managing and communicating with a large number of managed nodes, particularly when nodes become mobile, requiring manual tracking of IP addresses and individual command dissemination.
Innovation Solution
Establishing command and notification channels between a domain manager and managed nodes, allowing the domain manager to register and communicate with nodes via established channels, eliminating the need for manual address tracking and enabling simultaneous information dissemination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the EMS tracks addresses of all managed nodes individually (registering IP addresses and port numbers in directories or databases), then the EMS can identify and communicate with each node, but the complexity and workload increase significantly when the number of nodes increases or nodes become mobile
Solution Approach 1:
The patent introduces domain managers as intermediary entities between the EMS and managed nodes. Each domain manager manages a specific domain and maintains a directory of nodes within that domain. The EMS communicates with domain managers rather than directly tracking individual node addresses, thereby distributing the tracking complexity across multiple domain managers and reducing the burden on the central EMS.
Solution Approach 2:
The patent segments the network management function by dividing the network into multiple domains, each managed by a separate domain manager. This segmentation allows the address tracking responsibility to be distributed across multiple domain managers rather than concentrated in a single EMS, reducing the complexity for any single management entity.
2Reliability
If the EMS sends commands and information individually to each managed node via the domain manager (one method invocation per node), then each node receives the command, but the time and resources required increase with the number of nodes
Solution Approach 1:
The patent enables the domain manager to merge multiple individual command transmissions into a single broadcast operation. Instead of the EMS sending separate commands to each node, the domain manager receives one command from the EMS and simultaneously distributes it to all managed nodes in its domain, significantly reducing the time required for command dissemination.
Solution Approach 2:
The domain manager creates copies of the command received from the EMS and distributes these copies to multiple managed nodes simultaneously. This copying mechanism allows one original command to be replicated and sent to numerous nodes in parallel, reducing the overall time required for command delivery compared to sequential individual transmissions.
3Adaptability or versatility
If the system supports mobile managed nodes that acquire new addresses, then the system adapts to node mobility, but the address tracking and registration overhead increases
Solution Approach 1:
The patent implements self-service registration where managed nodes automatically register themselves with the appropriate domain manager when they join the network or acquire new addresses. Nodes autonomously provide their identity and address information without requiring manual registration by the EMS, reducing the registration management complexity while maintaining adaptability to mobility.
Solution Approach 2:
The system establishes feedback mechanisms where managed nodes notify domain managers of their presence and address changes through automatic registration. Domain managers maintain updated directories of nodes in their domains, providing real-time feedback information that enables the system to adapt to mobile nodes without increasing overall registration complexity.
Data Source
AI summary
A device associated with a network receives a register request from a managed node connected to the network, where the register request requests registration of the managed node. The device also establishes a command channel, for sending one or more commands, with the managed node based on the register request, and establishes a notification channel, for sending one or more notifications, with the managed node based on the register request.
