Proxy-Based Communication Session Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, establishing a communication session is inefficient due to the lengthy process of link setup and teardown, especially for brief messages, resulting in significant unproductive network bandwidth usage.
Innovation Solution
A proxy device located in proximity to a network node device is used to establish a communication session on behalf of a communication terminal, exchanging messages with the network node to reduce the time required for session establishment, utilizing a rapid-access message that includes necessary information for authentication and service type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a terminal establishes a communication session directly with a network node device, then authentication and service setup are performed correctly, but the session establishment time is long (8-10 seconds)
Solution Approach 1:
A proxy device is introduced as an intermediary between the terminal and network node device. The proxy receives a rapid-access message from the terminal and performs the complete session establishment message exchange with the network node device, thereby mediating the interaction and reducing the time the terminal must wait for session establishment.
Solution Approach 2:
The proxy device performs session establishment actions in advance by maintaining ready-state connections with network node devices. When a terminal needs to communicate, the proxy can immediately initiate or resume sessions without requiring the terminal to wait through the entire authentication and setup process each time.
2Productivity
If brief messages are transmitted over established links, then communication is reliable, but link usage efficiency is low due to lengthy setup and teardown processes
Solution Approach 1:
The proxy device acts as a mediator that manages link lifecycle on behalf of terminals. It establishes and maintains connections with network node devices, allowing terminals to send brief messages without incurring the full overhead of session establishment and teardown, thereby improving link usage efficiency.
Solution Approach 2:
The proxy device maintains continuous or near-continuous communication sessions with network node devices, keeping links in an active or ready-state. This allows brief terminal messages to be transmitted immediately without repeated setup/teardown cycles, ensuring continuous useful action rather than intermittent link usage.

AI summary
A technique for proxy-based establishment of a communication session between a communication terminal and a network node device. In one example technique, a rapid-access message is received at a proxy device located in proximity to a network node device. The rapid-access message is received from a communication terminal. In response to the rapid-access message, the proxy device exchanges a plurality of messages with the network node device to perform a plurality of session establishing phases such that the proxy device establishes the communication session with the network node device on behalf of the communication terminal. The proxy device then transmits at least one confirmation message to the communication terminal to notify the communication terminal of the establishment of the communication session between the communication terminal and the network node device.
