Secure Proxy for Flat Network Session Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in efficiently managing and transferring sessions between different subnets and telecommunications protocols, particularly in flat networks where scalability and security are critical, especially in high data rate mobile access technologies like HDR and 1xEV-DO.
Innovation Solution
A proxy system is introduced that communicates with both internet protocol networks and mobile operator networks, facilitating the transfer of sessions between access points by modifying, authenticating, encrypting, and routing communications, and can be distributed across multiple access points for load balancing and fault tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a proxy system is introduced to manage sessions between subnets and protocols, then scalability and security are improved, but device complexity increases
Solution Approach 1:
The patent introduces a proxy as an intermediary component that mediates between access points and mobile operator networks. The proxy handles session management, protocol translation, and authentication, allowing the network to scale without increasing complexity at the access point level. Multiple access points can be managed through a single proxy entity, improving scalability while containing complexity in a dedicated management function.
2Productivity
If session transfer functionality is implemented across multiple subnets, then network efficiency is improved, but device complexity increases
Solution Approach 1:
The proxy is designed with multi-functionality to handle various session transfer scenarios across different subnets and protocols. It can manage both active and dormant sessions, support different telecommunications protocols, and operate across multiple access points. This universal design improves network efficiency by consolidating multiple functions into a single versatile component rather than requiring separate specialized systems.
3Reliability
If authentication and encryption operations are performed by the proxy, then security is improved, but use of energy increases
Solution Approach 1:
The patent combines multiple security functions including authentication, encryption, and decryption into a single proxy system. By merging these operations rather than distributing them across multiple separate systems, the patent reduces overall energy consumption while maintaining comprehensive security coverage. The proxy consolidates computational tasks that would otherwise be performed by multiple independent devices.

AI summary
A proxy is in communication with an internet protocol network and a mobile operator network. The proxy receives first communications from access points via the internet protocol network, transmits content from the first communications to the mobile operator network, receives second communications from the mobile operator network, and transmits content from the second communications to the access points via the internet protocol network. The proxy may perform operations based on the first and second communications received from either the access points, or from the mobile operator network. The operations performed by the proxy may include modifying the communications, saving certain information regarding the communications, performing authentication, encryption, or decryption of the communications, determining a destination for the communications, or sending the communications to a destination.
