Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public safety communication systems face challenges in managing group communication scenarios, particularly in non-network controlled environments, where collisions and lack of control over participant actions lead to inefficient use of communication channels and limited integration with commercial wireless systems.
Innovation Solution
A user device with a transceiver configured for group communication using separate data and signaling channels, allowing network-controlled and non-network-controlled scenarios, enabling efficient resource management and integration of public safety features into commercial systems by prioritizing transmission requests and coordinating channel use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to transmit information in non-network controlled group communication scenarios, then group communication functionality is provided, but channel collisions and signal corruption occur when multiple users transmit simultaneously
Solution Approach 1:
The patent segments the communication control function by introducing a dedicated signaling channel separate from the data channel. Transmission requests are segmented and handled independently on the signaling channel, allowing the network to manage multiple users without channel collisions while maintaining group communication functionality.
Solution Approach 2:
The patent introduces the network as an intermediary mediator between users in non-network controlled scenarios. The network receives transmission requests on the signaling channel, manages channel access coordination, and grants permission for data transmission, thereby preventing simultaneous transmissions and signal corruption while enabling group communication.
2Ease of operation
If a second transmitter requests transmission while another user is already broadcasting in non-network controlled scenarios, then user transmission requests are accommodated, but the request disturbs and corrupts the current broadcast
Solution Approach 1:
The patent requires users to submit transmission requests in advance on the signaling channel before actual data transmission. This preliminary action allows the network to evaluate and coordinate requests, granting permission only when the channel is available, thereby preventing disturbance to ongoing broadcasts while accommodating user transmission needs.
Solution Approach 2:
The patent implements a feedback mechanism where the network responds to transmission requests with permission or rejection signals on the signaling channel. This feedback loop allows the network to inform users whether their transmission request will be granted, preventing them from initiating transmissions that would corrupt ongoing broadcasts while still accommodating valid requests.
3Adaptability or versatility
If public safety functionality is integrated into commercial group communication technology, then economies of scale and broader market application are achieved, but control and coordination mechanisms must be adapted from specialized to general-purpose systems
Solution Approach 1:
The patent creates a universal control mechanism using separate signaling and data channels that can serve both public safety and commercial group communication needs. The signaling channel provides network-controlled coordination that adapts to different application requirements, enabling a single system to handle diverse communication scenarios from emergency services to commercial group calls.
