Solution Overview

Problem

Current telecommunications networks face delays in establishing communication sessions due to the time required to set up active connections with terminals, especially when they are in idle mode, which increases the overall session setup time.

Innovation Solution

A network service system that generates and sends a connection request message ahead of the session setup message, allowing the telecommunications network to initiate an active connection with the terminal earlier, thereby reducing the delay in session setup time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the session setup message is sent directly to the terminating terminal without pre-establishing connection, then the network service system maintains simpler operation procedures, but the session setup time increases due to connection establishment delays

Engineering Contradiction:
Improvesession setup timeVSAvoidnetwork service system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The network service module generates and sends a connection request message to the terminating leg before the session setup message arrives. This preliminary action initiates connection establishment with the telecommunications network in advance, so that when the session setup message is forwarded, the connection is already active or being established, thereby reducing overall session setup time.

Inventive Principle:
Principle #10Preliminary action

2Speed

If the connection request message is sent before the session setup message, then the session setup time is reduced, but the message routing complexity increases

Engineering Contradiction:
Improveconnection establishment speedVSAvoidmessage routing complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The message flow is segmented into two distinct phases: a connection request phase that occurs first to establish connectivity, and a session setup phase that follows. The network service module separately handles the connection request message and the session setup message, routing them through different paths at different times. This segmentation allows the system to optimize each phase independently while managing overall complexity.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the network service module generates connection request message in advance, then the terminal connection is established faster, but the network service system requires additional processing steps

Engineering Contradiction:
Improveterminal connection establishment rateVSAvoidnetwork service module processing steps
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The network service module performs preliminary processing by generating and sending the connection request message before the session setup message is received. This advance processing establishes the connection foundation early, enabling faster terminal connection establishment. The additional processing step is concentrated at the beginning of the interaction sequence.

Inventive Principle:
Principle #10Preliminary action

AI summary

A network service system for a telecommunications network and for initiating a communication session between a first terminal for a first user and a second terminal for a second user. The network service system comprises a plurality of network modules associated with the first user. The network service system is configured to: receive a session setup message originating from the first terminal and addressed to the second terminal, wherein the session setup message comprises a request to initiate the communication session between the first terminal and the second terminal; and route the received session setup message through an originating leg in the network service system and send the session setup message to a terminating leg. The originating leg of the session setup message includes a network service module configured to generate, in response to receiving the session setup message in the originating leg, a connection request message addressed to the second terminal and for initiating connection of the second terminal to a telecommunications network serving the second terminal. The network service system is further configured to send the connection request message to the terminating leg before sending the session setup message to the terminating leg.
