Hub Device Superframe Synchronization for Alarm Notification Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network systems face inefficiencies in communicating alarm events across multiple premises, leading to network pollution and privacy concerns, as they often require additional messages beyond the standard superframe, which can result in bandwidth congestion and unnecessary data transmission.
Innovation Solution
Implementing a dynamic mode shifting mechanism between premise communication mode and community communication mode within the superframe, allowing for the alteration of slots to include alarm event data without additional messages, utilizing a single radio chip for multiple frequency bands, and optimizing bandwidth allocation to reduce traffic and jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional messages are broadcast to communicate alarm events across multiple premises, then alarm event communication coverage is improved, but network bandwidth congestion and pollution increase
Solution Approach 1:
The patent combines alarm event data with the existing periodic superframe broadcast structure. Instead of sending separate additional messages for alarm events, the system merges alarm information into the regular superframe slots that are already being transmitted at defined intervals. This approach maintains comprehensive alarm communication coverage while avoiding the network pollution that would result from extra standalone alarm messages.
Solution Approach 2:
The superframe structure serves multiple functions: it carries both regular sensor data communications and alarm event notifications. By making the superframe a universal communication vehicle that handles different types of data (sensor readings, alarm events, control commands), the system eliminates the need for separate dedicated alarm message channels, thereby reducing overall network traffic volume while maintaining full alarm communication capability.
2Measurement precision
If all hub devices process all received superframes, then alarm event detection accuracy is improved, but energy consumption and processing overhead increase
Solution Approach 1:
The patent implements selective processing where each hub device processes only specific portions of the received superframe based on its local context and needs. Instead of uniformly processing all superframe data, hub devices focus their processing efforts on relevant alarm event slots and ignore unrelated data. This localized processing approach maintains accurate alarm event detection while significantly reducing the energy consumption and processing overhead associated with analyzing every byte of every superframe.
Solution Approach 2:
Hub devices perform partial processing of superframes by selectively extracting and analyzing only the necessary alarm event information rather than processing the complete superframe structure. This partial action approach ensures that alarm events are detected with sufficient accuracy while avoiding the excessive energy consumption that would result from comprehensive processing of all superframe contents at every hub device.
3Device complexity
If a single radio chip operates at multiple frequency bands, then device complexity is reduced, but bandwidth allocation optimization becomes more difficult
Solution Approach 1:
The patent implements dynamic frequency band selection and slot allocation for the single radio chip. The system can dynamically switch between different frequency bands (e.g., 2.4 GHz and sub-1 GHz) and adjust the timing and content of superframe slots based on current network conditions, traffic requirements, and interference levels. This dynamic adaptability allows a single radio chip to effectively manage multiple frequency bands with optimized bandwidth allocation, maintaining versatility despite the simplified hardware configuration.

AI summary
Techniques for synchronizing superframes across apparatuses are disclosed. An apparatus for communication with a plurality of devices is set to a premise communication mode. While in the premise communication mode, the apparatus outputs a first superframe configured in a premise communication superframe mode allocating each slot of a plurality of slots for wireless communication to a first protocol at a first frequency band or a different second protocol. The apparatus transitions from the premise communication mode to a community communication mode. While in the community communication mode, the apparatus outputs a second superframe configured in a community communication superframe mode allocating at least one slot for wireless communication to the first protocol or the second protocol at the first frequency band, and at least one slot for wireless communication to a community beacon including data relating to a unique key recognizable by a remote apparatus.
