Broadcast Overhead Message Application Timing in Mobile Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the lack of a defined point of time for applying the Broadcast Overhead Message (BOM) leads to inefficiencies in channel allocation and initial detection delays, causing uncertainty in determining whether received BOM matches the previously transmitted one, especially when channel information changes frequently.
Innovation Solution
A method and apparatus for determining and applying a new BOM after a change application time-point, using a controller to manage the BOM application in a mobile communication system, ensuring accurate channel change detection and efficient operation by defining the BOM application time based on a BOM transition length, preamble, or burst length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If BOM is transmitted in broadcast overhead period without defined application time-point, then broadcast service can be provided, but initial detection delays occur and channel allocation efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-defining the BOM application time-point rule before actual BOM transmission occurs. The rule specifies that BOM shall be applied at the first slot boundary after being received, which is determined in advance by the system design. This eliminates the need for real-time decision-making at the receiver, thereby reducing initial detection delays while maintaining broadcast service provision.
Solution Approach 2:
The patent changes the parameter of BOM application timing from undefined to clearly defined. By specifying that BOM application occurs at slot boundaries (which are predetermined time points in the TDM frame structure), the system transforms an ambiguous timing parameter into a deterministic one, improving both detection speed and channel allocation efficiency.
2Adaptability or versatility
If BOM application time-point is not defined, then system flexibility is maintained, but uncertainty in BOM matching increases and system reliability deteriorates
Solution Approach 1:
The patent changes the timing parameter from undefined to defined by specifying BOM application occurs at slot boundaries. This deterministic timing rule eliminates BOM matching uncertainty while preserving system flexibility, as the rule can be applied universally across different broadcast scenarios without requiring system redesign.
Solution Approach 2:
The patent implements a feedback mechanism where the receiver determines BOM application timing based on the received BOM and the predefined rule. The receiver feeds back to the system (implicitly through correct decoding and application) that the BOM has been successfully applied at the appropriate slot boundary, ensuring reliable BOM matching across the system.
3Loss of time
If BOM is applied immediately upon receipt, then detection delay is reduced, but data transmission continuity may be compromised due to undefined timing
Solution Approach 1:
The patent applies preliminary action by pre-specifying that BOM application occurs at slot boundaries, which are predetermined time points in the TDM frame structure. This allows the receiver to apply BOM as soon as the next slot boundary occurs after receipt, minimizing detection delay while ensuring data transmission continuity through the structured timing framework.
Solution Approach 2:
The patent utilizes the periodic nature of slot boundaries in TDM frames to determine BOM application timing. By applying BOM at regular slot boundary intervals, the system achieves both rapid detection (applying BOM at the first opportunity) and transmission continuity (maintaining regular periodic structure for data flow).

AI summary
A system and method are provided for setting a point of time when information is applied in a mobile communication system. A broadcast overhead message including additional information is received and its application time-point is computed. The broadcast overhead message including the additional information is then applied at the computed time-point.
