Home Agent IPv4 IPv6 Session Binding Merge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems treat IPv4 and IPv6 sessions from a common device as separate sessions, leading to inefficient resource management and accounting challenges, as well as capacity limitations in home agents due to the need for dual bindings.
Innovation Solution
A method to combine IPv4 and IPv6 registration requests into a single session at a home agent, sharing a common binding, allowing for unified management and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bindings are created for IPv4 and IPv6 sessions at the home agent, then protocol-specific session management is achieved, but resource management efficiency deteriorates and capacity is limited
Solution Approach 1:
The patent merges IPv4 and IPv6 session bindings into a single unified binding structure at the home agent. This allows both protocol versions to share common binding information (care-of address, lifetime, authentication data), eliminating redundant storage and processing while maintaining protocol-specific functionality. The binding table stores a single entry per mobile node that accommodates both IPv4 and IPv6 protocol information.
Solution Approach 2:
The binding structure is designed to be universal, serving both IPv4 and IPv6 sessions simultaneously. The binding table entry includes fields that can accommodate both protocol versions (such as a unified care-of address field and protocol version indicators), allowing the same binding infrastructure to handle multiple protocol requirements without requiring separate dedicated structures for each protocol.
2Adaptability or versatility
If dual bindings are maintained for IPv4 and IPv6 at the home agent, then protocol compatibility is ensured, but accounting and capacity management become complex
Solution Approach 1:
The patent combines accounting and capacity management for IPv4 and IPv6 sessions into a single unified process. The home agent maintains one binding table entry per mobile node that tracks both protocol versions collectively, simplifying accounting calculations and capacity monitoring. Resource allocation decisions can be made at the binding level rather than at the individual protocol level, reducing management overhead.
Solution Approach 2:
While maintaining a unified binding structure, the patent segments protocol-specific information within the binding entry using protocol version indicators and conditional fields. This allows the system to treat IPv4 and IPv6 sessions uniformly at the binding level while preserving protocol-specific details where needed, achieving both simplification and compatibility.
3Measurement precision
If separate session tracking is used for IPv4 and IPv6, then protocol-specific traffic monitoring is maintained, but traffic tracking efficiency decreases
Solution Approach 1:
The patent merges traffic monitoring for IPv4 and IPv6 into a single unified tracking process at the home agent. By maintaining a single binding entry, the system can efficiently track all traffic from a mobile node regardless of protocol version, reducing processing time and resource consumption. The unified binding structure enables simultaneous monitoring of both protocol versions without requiring separate tracking mechanisms.

AI summary
Methods for registering a first internet protocol version registration request and a second internet protocol version registration request in a single binding on a home agent are provided. In embodiments, entries are recognized as sharing common information in an IPv4 and IPv6 binding table. The entries with common information are combined into one binding. Through the combining of the bindings, the IPv4 and IPv6 sessions are combined into one session.
