Repeater Open Burst Location Detection for Voice Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-site communication systems lack an effective mechanism for interrupting voice transmissions, which is crucial for emergency situations like a police officer needing to interrupt another officer during a call.
Innovation Solution
A method and apparatus that allow for interruptible voice communications by identifying an open burst location based on repeat delay, enabling the interruption of ongoing voice transmissions across a multi-site communication network, where repeaters manage channels and communicate through a backend network without a central controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a multi-site communication system uses conventional channel sharing without control mechanisms, then users can manually control channel access, but the system lacks the ability to interrupt ongoing voice transmissions
Solution Approach 1:
The system pre-establishes control channels that operate independently of traffic channels. These control channels are set up in advance to carry control messages including interrupt requests, allowing the system to quickly interrupt ongoing voice transmissions without waiting for channel availability or manual user action.
2Adaptability or versatility
If the system implements interrupt mechanisms, then voice transmissions can be interrupted for emergency situations, but the interrupt time increases due to channel allocation delays
Solution Approach 1:
The communication system is segmented into separate control channels and traffic channels. Control channels are dedicated specifically to carrying control messages including interrupt requests, while traffic channels handle voice transmissions. This segmentation allows interrupt messages to be transmitted independently without waiting for traffic channel availability, significantly reducing interrupt time.
Solution Approach 2:
Control channels act as intermediaries between the interrupting user and the ongoing voice transmission. The control channel carries the interrupt request message to the receiving site, which then processes the interruption and switches the traffic channel. This intermediary mechanism enables fast interruption without direct interference with the voice transmission path.
3Productivity
If control channels are used to allocate traffic channels in trunked systems, then communication resources are efficiently shared, but the interruption mechanism becomes complex due to resource allocation overhead
Solution Approach 1:
The system separates control functions from traffic functions by implementing dedicated control channels. These control channels handle all control messaging including interrupt requests, channel allocations, and acknowledgments. This segmentation simplifies the interruption mechanism by providing a dedicated path for control messages, eliminating the need to complexly manage resource allocation during interruptions.
Solution Approach 2:
Control channels are pre-configured and always available for control messaging. The system establishes these control channels in advance with predefined characteristics (such as specific frequencies or time slots), so that when an interrupt is needed, the control message can be immediately transmitted without needing to allocate or configure channels dynamically, reducing complexity.

AI summary
A method for interrupting voice transmissions within a multi site communication system (100) includes operating a repeater (112) to engage in an interruptible voice communication; to identify an open burst location based on a repeat delay when the interruptible voice communication is sourced directly via a wireless network, and to identify the open burst location as irrelevant when the interruptible voice communication is indirectly sourced via a wireless network; and repeat the interruptible voice communication including the open burst location.
