Wireless Terminal Channel Interruption and Resumption Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when a call is interrupted to prioritize another urgent call, the interrupted terminal devices must compete for the channel, leading to inefficient communication as they may not be able to resume their call if the channel is not acquired promptly.
Innovation Solution
A terminal device is equipped with a detector to identify ongoing communications, a requesting unit to interrupt the current call, and an invitation unit to prompt the original terminal devices to resume communication once the interrupting call is terminated, ensuring preferential resumption of the interrupted call by transmitting an invitation signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If interrupting communication is implemented to prioritize urgent calls, then communication priority for urgent calls is improved, but channel availability for resuming original calls deteriorates
Solution Approach 1:
The system performs preliminary actions by storing communication state information before interrupting communication occurs. When the interrupting call ends, the original call can quickly resume because the necessary channel allocation and state information were prepared in advance, eliminating the need to compete for channels from scratch.
Solution Approach 2:
The notification unit provides feedback to the transmitting and receiving terminal devices when the interrupting call terminates, prompting them to resume communication. This feedback mechanism ensures that original call participants are immediately notified and can quickly re-acquire the channel without prolonged delay or complex competition protocols.
2Adaptability or versatility
If terminal devices compete for channel after interrupting call terminates, then channel allocation fairness is improved, but communication resumption efficiency deteriorates
Solution Approach 1:
The storage unit preserves channel allocation information and communication state data before the interrupting call occurs. When the interruption ends, this pre-stored information enables the original terminal devices to quickly resume communication without going through a lengthy channel competition process, thereby maintaining both fairness and efficiency.
Solution Approach 2:
The notification unit acts as an intermediary between the system and the terminal devices involved in the original call. It transmits notification signals to prompt resumption, mediating the channel allocation process and eliminating the need for direct competition between terminal devices, thus improving resumption efficiency while maintaining fair channel allocation.
3Measurement precision
If complicated user operations are required to resume original call, then user control precision is improved, but operation simplicity deteriorates
Solution Approach 1:
The system provides self-service functionality by automatically notifying the transmitting and receiving terminal devices when the interrupting call terminates. The notification unit sends prompts that enable the original call participants to resume communication with minimal user action, eliminating complicated manual operations while maintaining precise user control through simple confirmation gestures or automatic resumption.

AI summary
A detector detects communication from a transmitting terminal device to a receiving terminal device on a given channel. A storage stores information on the transmitting terminal device and the receiving terminal device when the detector detects the communication. A requesting unit requests the transmitting terminal device for an interruption in the communication when the detector detects the communication. A communication unit performs interrupting communication on the given channel when the transmitting terminal device stops the communication on the given channel in response to the request by the requesting unit. An invitation unit prompts the transmitting terminal device and the receiving terminal device to resume the communication on the given channel based on the information stored in the storage, when the communication unit terminates the interrupting communication.
