Access Service Node Identity-Location Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IP address system, particularly in TCP/IP, faces issues with host mobility and dual function overload, leading to increased route load and application interruptions, as it does not separate access identifiers from location identifiers effectively, and lacks compatibility with both IPV4 and IPV6 networks.
Innovation Solution
The proposed architecture introduces separate access identifiers (AID) and Routing-Location Identifiers (RID) to segregate the dual functions of IP addresses, using an Access Service Node (ASN) to manage AID-RID mappings, ensuring compatibility with IPV4 and IPV6 terminals and networks, and reducing route load through a dual-plane forwarding system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the IP address serves both as location identifier and access identifier, then the dual function is achieved, but the route load increases and application interruption occurs during host mobility
Solution Approach 1:
The patent segments the IP address functionality into two separate identifiers: L (location identifier) and N (namespace identifier/access identifier). The L address identifies the network location and routing path, while the N address identifies the application namespace and access point. This segmentation allows the location to change without affecting the access identifier, thereby maintaining application continuity during host mobility while preserving the dual function capability through separate identifiers.
2Quantity of substance
If the IP address space is expanded to meet service requirements, then the address number capacity increases, but the route load and complexity increase
Solution Approach 1:
The patent divides the address space into two components: L (location) and N (namespace). The L address space is optimized for routing efficiency with a smaller, more manageable scope, while the N address space provides the expanded address capacity needed for service applications. This segmentation allows large address spaces to be supported without proportionally increasing route load, as routing decisions are primarily based on the compact L address.
Solution Approach 2:
The patent extracts the access identifier function (N address) from the location identifier function (L address). By taking out the namespace identification from the routing function, the system can support expanded address spaces for applications without requiring the route to handle the full complexity of large address spaces, thereby reducing route load while maintaining address capacity.
3Adaptability or versatility
If the access identifier is changed to support mobility, then the mobility support is improved, but the application connection is interrupted
Solution Approach 1:
The patent segments the identifier into L (location) and N (namespace/access) components. During mobility, the L address changes to reflect the new location, while the N address remains constant to maintain application connections. This segmentation enables mobility support through location changes without disrupting application stability, as the access identifier (N) remains unchanged.
Solution Approach 2:
The patent introduces the N address as an intermediary between the application and the network location. The application communicates through the stable N address, which acts as a mediator that abstracts away the changing L address. This intermediary mechanism allows the application connection to remain stable even as the underlying location (L) changes during mobility.
4Device complexity
If the existing IP address system is used without separation, then the system simplicity is maintained, but the route load increases and mobility is not supported
Solution Approach 1:
The patent applies segmentation by dividing the identifier into L and N components, which enables mobility support and route load reduction through specialized handling of each component. The L component handles location-specific routing, while the N component handles application-specific access, creating a more efficient system despite the added structural element of separation.
Solution Approach 2:
The patent changes the parameter structure from a single IP address to a paired (L, N) identifier system. This parameter change fundamentally alters how addressing and routing work, enabling mobility support and route load optimization by changing the fundamental parameters of the addressing system rather than trying to modify the existing single-address approach.

AI summary
The present invention provides a communication method, and a method for forwarding the data message during the communication process and a communication node thereof. The communication method is used in the identity identifier and position separation network, and includes the following steps an Access Service Node (ASN) establishes the binding relationship between the first identifier of the terminal and the transceiver link for each access terminal, when receiving the data message sent from the terminal on the transmitting-receiving link, if the source address of the data message is the second identifier of the terminal, the ASN converts the source address to the first identifier of the terminal and sends the data message to the core network to forward it. The present invention also provides another communication method While the requirement for the number of the coding space is met, the present invention realizes the intercommunication and interconnection with the traditional IP network, realizes the compatibility with the upper application of 1PV4/IPV6, and supports the various application programs of the IPv4/IPv6 network to transplant smoothly to the network-based architecture of identity identifier and position separation.
