Residential Gateway Management via Fixed Local Addressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current residential gateways require complex setup and maintenance procedures, and service providers face challenges in remotely managing them, especially when authentication or IP address allocation fails, leading to inconvenience and potential malfunctions.
Innovation Solution
Implementing a system that allows remote management of residential gateways by using predetermined management addresses and network address translation to enable communication and perform tasks like software updates, even when the gateway is not authenticated or has not acquired a dynamic IP address, ensuring minimal unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If residential gateways use fixed IP addresses for local installation, then ease of local setup is improved, but remote accessibility through the Internet deteriorates
Solution Approach 1:
The patent segments the IP address usage into two distinct modes: a fixed local IP address for installation and maintenance access, and a dynamic public IP address for Internet communication. This segmentation allows the gateway to fulfill both local ease-of-setup and remote accessibility requirements simultaneously through different network interfaces or protocol modes.
2Object-affected harmful factors
If service providers implement authentication and IP address allocation processes, then network security is improved, but system reliability deteriorates when authentication fails
Solution Approach 1:
The patent implements preliminary configuration of essential gateway parameters and authentication credentials before the gateway connects to the network. This preliminary action ensures that even if authentication or IP allocation fails later, the gateway can still perform basic functions and allow service providers to remotely access and reconfigure it.
Solution Approach 2:
The patent incorporates fallback mechanisms and default configurations that cushion against authentication or IP allocation failures. These pre-prepared contingencies ensure that security requirements are maintained while preventing complete system failure, allowing the gateway to operate in a degraded but functional state.
3Ease of operation
If residential gateways require customer setup procedures, then ease of operation deteriorates, but extent of automation improves
Solution Approach 1:
The patent enables the residential gateway to perform self-configuration and self-registration with the service provider network automatically upon connection. The gateway autonomously obtains network parameters, configures its services, and registers itself without requiring customer intervention, thereby improving ease of operation while maintaining high automation.
Solution Approach 2:
The patent performs preliminary configuration of the gateway during manufacturing or initial provisioning, pre-configuring essential parameters, authentication methods, and service profiles. This preliminary action reduces or eliminates the need for customer setup procedures while maintaining automated operation.
Data Source
AI summary
System management functions are remotely performed on customer premises equipment (CPE), such a residential gateway, even if the CPE has not been authenticated or dynamically allocated an IP address or otherwise is not in a state that enables normal communication with the network. CPE management information is communicated using an IP address identifying a destination CPE but exclusively associated with CPE management. The access node that receives the CPE management information reconfigures the packets to translate the address to a fixed, non-public address. The same fixed address can be shared by all of the CPE's connected to the access node. The CPE recognizes the fixed address as though it were being addressed locally rather than through the network and is therefore able to receive the CPE management information even if the CPE has not been authenticated or dynamically allocated an IP address.
