IP Edge Node IPv6 Host Registration QoS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network technologies face challenges in maintaining separate Quality of Service (QoS) requirements for multiple mobile hosts with different service levels connected via the same fixed network, as existing mechanisms fail to adequately manage and enforce distinct QoS for each device.
Innovation Solution
The implementation of a mechanism in a residential gateway (RG) and IP edge node that registers a unique host ID for each connected mobile host, establishes and manages independent IP Connectivity Access Network (IP-CAN) sessions, and obtains distinct QoS parameters from the mobile network, allowing for separate QoS enforcement for each host.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single fixed network connection is shared by multiple mobile hosts, then network resource utilization is improved, but the ability to maintain separate QoS requirements for each host deteriorates
Solution Approach 1:
The patent segments the shared network connection by creating separate IP-CAN sessions for each mobile host. The residential gateway maintains individual session contexts for each host, allowing the network to treat each host as a separate logical entity while physically sharing the same fixed network connection. This segmentation enables distinct QoS parameters to be assigned and enforced per host.
Solution Approach 2:
The residential gateway acts as an intermediary between the mobile hosts and the fixed network. It receives IP-CAN session establishment requests from each host, creates separate session contexts, and manages individual QoS parameters. This intermediary function allows the gateway to enforce separate QoS requirements while maintaining efficient resource sharing through a single physical connection.
2Reliability
If separate IP-CAN sessions are established for each mobile host, then separate QoS enforcement is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple mobile host sessions under a single residential gateway context. Instead of requiring separate gateway infrastructure for each host, the gateway consolidates session management functions, maintaining individual session contexts while sharing common resources such as authentication mechanisms, QoS parameter storage, and network interface management. This merging reduces overall system complexity while preserving per-host QoS enforcement.
3Productivity
If multiple mobile hosts connect via the same fixed network, then network efficiency is improved, but the ability to authenticate and manage each host independently deteriorates
Solution Approach 1:
The patent segments host identification and authentication by incorporating unique host identifiers into the IP-CAN session context. Each mobile host is authenticated independently through the residential gateway, which maintains separate authentication states and QoS parameter sets for each host. This segmentation enables efficient resource sharing while preserving independent authentication and management capabilities.

AI summary
A computer program product implemented in an Internet Protocol (IP) edge node positioned in a fixed access network, the computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor cause the IP edge node to receive an address registration request from a residential gateway (RG), wherein the address registration request comprises an IP version six (IPv6) address of a third Generation Partnership Project (3GPP) visiting mobile host connected to a local fixed network associated with the RG and a host identifier (ID) assigned to the visiting host and not to any other host in the local fixed network; establish an IP Connectivity Access Network (IP-CAN) session for the visiting host; and manage quality of service (QoS) for the visiting host independently of other hosts in the local fixed network by managing the visiting host IP-CAN session.
