Mobile Device OTA Programming via Broadcast Control Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device programming methods via over-the-air (OTA) updates lack specificity and efficiency, as they often broadcast software updates across multiple logical channels, leading to unnecessary resource usage and potential rejection of intended updates.
Innovation Solution
Configuring mobile devices to accept software updates specifically through designated logical channels, such as the Broadcast Control Channel (BCCH), allowing for targeted programming based on manufacturer, feature, or user group, while rejecting irrelevant channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If software updates are broadcast across multiple logical channels, then update coverage is improved, but resource usage increases and update accuracy decreases
Solution Approach 1:
The patent segments the update distribution by dividing logical channels into manufacturer-specific groups. Each manufacturer's updates are transmitted only on channels assigned to that manufacturer, preventing unnecessary broadcasting across all channels. This segmentation maintains comprehensive coverage while reducing redundant resource consumption.
Solution Approach 2:
The patent applies local quality by assigning specific logical channels to specific manufacturers or device types. Instead of uniform broadcasting across all channels, each channel is optimized for a particular manufacturer's devices, ensuring that updates are transmitted with appropriate quality and relevance to the target devices while minimizing overall network resource usage.
2Adaptability or versatility
If software updates are broadcast across multiple logical channels, then update coverage is improved, but update accuracy decreases
Solution Approach 1:
By segmenting channels by manufacturer, the system ensures that devices only receive updates from their designated manufacturer's channel. This prevents devices from receiving irrelevant updates from other manufacturers, thereby improving update accuracy while maintaining coverage across all device types through their respective dedicated channels.
Solution Approach 2:
Each logical channel is configured with specific quality characteristics tailored to its intended manufacturer or device type. This local optimization ensures that updates transmitted on each channel are highly relevant and accurate for the target devices, improving overall update precision while maintaining comprehensive coverage.
3Adaptability or versatility
If devices accept updates from all logical channels, then update availability is improved, but error rate increases
Solution Approach 1:
The patent implements segmentation by configuring devices to monitor and accept updates only from their designated manufacturer's logical channels. This segmentation maintains update availability for each device type while preventing errors caused by accepting incompatible updates from unrelated channels.
Solution Approach 2:
The system applies preliminary anti-action by pre-configuring devices with knowledge of which logical channels are appropriate for their manufacturer. This prevents devices from attempting to process irrelevant or incompatible updates before they can cause errors, thereby reducing the error rate while maintaining proper update availability.

AI summary
In a communications system, one or more mobile devices may be programmed through the use of an assigned channel of a logical channel. For example, a broadcast control channel (BCCH) transmission may be received by one or more mobile devices, the transmission comprising a set of instructions to program the mobile devices. The BCCH transmission may be used to program certain mobile devices, such as a type or brand of device, or mobile devices having certain features, such as call waiting. The mobile device may be configured to accept a transmission, such as a packet in a GPRS network, on one channel while rejecting a transmission on other channels. Further, the mobile device may be reconfigured to accept additional channel transmissions or reject currently approved channel transmissions.
