Wireless System State Broadcast Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless broadcast environments, wireless devices face significant power and resource drainage when continuously receiving and processing updated system state information, which reduces their standby time and efficiency.
Innovation Solution
The method involves sending a primary message with abbreviated data indicating system state changes, allowing devices to determine if updates are needed, and if so, requesting or listening for further information, thereby conserving power and processing resources.

Engineering Contradiction Analysis
1Reliability
If wireless devices continuously receive and process updated system state information, then the latest system state information is obtained, but power consumption and processing resources are significantly drained
Solution Approach 1:
The system state information is segmented into two parts: a compact indicator (first information) that is always transmitted, and detailed update information (second information) that is transmitted only when changes occur. Devices only need to process the compact indicator continuously, and only retrieve detailed information when necessary, thereby reducing continuous processing load and power consumption while maintaining information currency.
Solution Approach 2:
The essential change indicator is extracted from the full system state information and transmitted separately. This allows devices to quickly determine whether full system state updates are needed without processing the entire information set continuously, reducing unnecessary processing and power consumption when no changes have occurred.
2Reliability
If wireless devices continuously receive and process updated system state information, then the latest system state information is obtained, but processing resources are significantly consumed
Solution Approach 1:
The information transmission is segmented into a compact indicator portion and detailed update portion. Devices only process the compact indicator continuously, which requires minimal processing resources. Full processing of detailed system state information is only performed when the indicator signals a change, thereby reducing average processing resource consumption while maintaining information currency.
Solution Approach 2:
The change detection function is extracted into a separate compact indicator that can be processed independently and efficiently. This separates the frequent low-complexity indicator processing from the less frequent high-complexity detailed information processing, optimizing the balance between information currency and processing resource usage.
3Use of energy by moving object
If abbreviated primary message is sent to indicate system state changes, then power consumption and processing resources are reduced, but additional message transmission is required for complete information
Solution Approach 1:
The message structure is segmented into a compact primary message containing change indicators and a secondary detailed message containing full system state information. This segmentation allows the system to transmit minimal information continuously (reducing power consumption) while maintaining the capability to transmit complete information when needed (managing complexity through structured separation).

AI summary
Apparatus and methods for communication system state information change to wireless devices in a content server network in a resource and power efficient manner are disclosed. In particular, a disclosed method for conveying system state information to a wireless device includes sending a primary message including first information configured to communicate a current system state to the wireless device, and then sending second information set usable by the wireless device to update system state information. By summarizing or abbreviating the first information, a receiving device can easily compare to past system states to determine whether further processing, such as processing of the second information, is needed, thereby affording the conservation of processing and power resources of a receiving device. Corresponding apparatus are also disclosed.
