Broadcast Firmware Update via Service Guide Fragment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile broadcast systems face inefficiencies in updating firmware for multiple terminals due to resource-intensive one-to-one updates, which are often impossible in environments with limited radio resources.
Innovation Solution
A method and system for simultaneously updating firmware of multiple terminals using a service guide in a broadcast system, where a firmware package file is broadcasted and detected by terminals for automatic update, reducing the need for individual interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-to-one firmware update method is used, then update reliability is improved, but radio resource consumption increases and productivity decreases
Solution Approach 1:
The patent merges multiple one-to-one update interactions into a single broadcast transmission. The firmware update server transmits update information and firmware files to multiple terminals simultaneously through broadcast channels, consolidating what would otherwise be numerous individual update sessions into one efficient operation, thereby improving productivity while maintaining reliability through structured broadcast protocols
2Manufacturing precision
If one-to-one firmware update method is used, then update control precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the firmware update process into distinct functional modules: update information transmission, firmware file delivery, and terminal-side reception and installation. This segmentation allows precise control of each phase independently while simplifying the overall system architecture by dividing complex update management into manageable components handled by different system elements
3Productivity
If broadcast-based firmware update is used, then productivity is improved, but detection and measurement complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where terminals transmit their current firmware version information and reception status back to the firmware update server. This feedback loop enables the server to accurately detect which terminals need updates and verify successful reception, simplifying the detection process while maintaining high broadcast-based update efficiency
Data Source
AI summary
A method and apparatus for updating firmware of terminals in a mobile broadcast system including a Broadcast Service Distribution/Adaptation fragment (BSDA) and a Broadcast service Subscription Management (BSM). The method includes requesting creation of a content fragment, by the BSM, by transmitting a firmware package file for a firmware update of the terminals to the BSDA; creating a content fragment including the firmware package file and broadcasting the created content fragment to the terminals by the BSDA; detecting the firmware package file from the received content fragment; and performing the firmware update using the firmware package file.
