User Terminal Operational Information Delivery via Stolen Timeslots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telecommunications systems incur significant load on the radio interface when transmitting operational information, such as location and status updates, due to the need for intermediate nodes and excessive use of short data messages, which limits the frequency and practicality of such applications.
Innovation Solution
Delivering dynamically varying operational information directly between user terminals via a timeslot stolen from a traffic channel allocated for their connection, reducing the overhead and load on the radio interface by eliminating the need for additional resource access and minimizing the transmission of identity and header data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operational information is transmitted via intermediate nodes using short data messages, then information delivery is achieved, but the load on the radio interface and common control channel increases significantly
Solution Approach 1:
The patent uses the existing traffic channel between two user terminals as an intermediary medium to deliver operational information. Instead of using the common control channel or intermediate nodes, the traffic channel serves as the mediator, allowing direct peer-to-peer information exchange without increasing overall system load.
Solution Approach 2:
The traffic channel, which is already allocated for user data transmission, is made multi-functional by also carrying operational information signaling. This allows the same channel resource to serve both voice/data communication and operational information delivery, eliminating the need for separate signaling channels.
2Adaptability or versatility
If operational information is delivered through presence servers in packet-based systems, then information distribution to multiple users is achieved, but the overhead and complexity of the system increases
Solution Approach 1:
The patent extracts the operational information delivery function from the complex presence server infrastructure and implements it directly at the user terminal level. By removing the intermediate presence server component, the system achieves simpler architecture while maintaining the ability to distribute operational information to multiple users through direct peer-to-peer communication.
3Loss of information
If location monitoring applications are implemented in user terminals, then operational awareness is improved, but the frequency and practicality of such applications are limited due to radio interface constraints
Solution Approach 1:
The patent enables continuous and frequent exchange of operational information by utilizing the ongoing traffic channel communication between users. Instead of periodic or event-driven updates through constrained channels, the system allows continuous information flow during active calls, maintaining uninterrupted operational awareness.

AI summary
A method for enhancing application of operational information in a communication system. A channel (CH) is allocated for a connection between a user terminal (UT1) and at least one other user terminal (UT2). Operational information (posi) on the user of the user terminal (UT1) is determined and included in a data item (DI) of a user plane signaling message. The user plane signaling message is transmitted to the at least the other user terminal in a timeslot stolen from the channel (CH) allocated to the connection. Delivery of operational information between users is facilitated with reduced overhead and without essentially incurring additional load to the radio interface between the user terminals.
