Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth technologies face challenges in managing complex connections and optimizing data transmission periods based on the type of content, particularly in game services, leading to inefficiencies and increased energy consumption.
Innovation Solution
A method and device for transmitting data in a short-range wireless communication system, specifically using Bluetooth technology, that configures an optimized data transmission period based on the type of content, allowing for reconfiguration of data transmission periods in response to changes in content type, and utilizes data transmission period mapping information to recommend optimal periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If data transmission period is fixed for all content types, then device complexity is reduced, but energy consumption increases due to unnecessary frequent transmissions for low-priority content
Solution Approach 1:
The patent implements dynamic data transmission period configuration where the master device adjusts the transmission period based on the type of content being transmitted. Different content types (e.g., game control data vs. status data) are assigned different transmission periods, allowing the system to optimize energy consumption by reducing transmission frequency for low-priority content while maintaining low latency for high-priority content. This dynamic adjustment resolves the contradiction by adapting the transmission period to actual needs rather than using a fixed period.
Solution Approach 2:
The patent changes the transmission period parameter based on content type classification. The master device identifies the content type and selects an appropriate transmission period from multiple available periods, thereby changing the transmission parameter dynamically. This allows the system to balance energy consumption and responsiveness by using longer periods for non-critical data and shorter periods for time-sensitive data, resolving the contradiction between energy efficiency and device complexity.
2Use of energy by moving object
If data transmission period is optimized for each content type, then energy consumption is reduced, but connection management complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the master device automatically configures the data transmission period based on content type without requiring manual intervention or complex negotiation protocols. The system maintains a mapping between content types and transmission periods, and automatically selects the appropriate period when new content is identified. This automation reduces connection management complexity while still achieving energy optimization through content-aware transmission period selection.
Solution Approach 2:
The patent performs preliminary configuration by establishing content type to transmission period mappings in advance. The master device pre-defines which transmission periods should be used for different content types, so that when data transmission is needed, the appropriate period can be quickly selected without complex real-time decision-making. This preliminary action simplifies connection management while enabling energy-efficient transmission by having the right configurations ready beforehand.
3Area of stationary object
If transmission distance is extended beyond 100m, then coverage area is increased, but signal reliability deteriorates
Solution Approach 1:
The patent segments the wireless communication system into a master device and multiple slave devices, allowing for extended network coverage through hierarchical structure. The master device coordinates multiple slaves, enabling the system to cover areas beyond what a single device could reach while maintaining reliable communication through centralized coordination. This segmentation allows coverage extension without sacrificing reliability by distributing functions across multiple devices under master control.
Solution Approach 2:
The master device acts as an intermediary that coordinates communication between slave devices and external systems. By introducing this intermediary layer, the system can extend coverage area through multiple slaves while maintaining signal reliability through the master's coordination and error handling. The intermediary manages data transmission periods and content types, ensuring reliable communication even as the network expands beyond 100m range.

AI summary
A method of transmitting and receiving data in a short-range wireless communication system, and a device therefor are provided. More specifically, a method of receiving, by a master device, data in a short-range wireless communication system comprises transmitting, to a slave device, a read request message requesting a reading of at least one data transmission period supported by the slave device; receiving, from the slave device, a read response message including information on the at least one data transmission period supported by the slave device; receiving, from the slave device, a message indicating a selection of a specific content among at least one content related to a service provided by the master device; transmitting, to the slave device, a message for configuring a specific data transmission period among the at least one data transmission period supported by the slave device to the slave device based on (i) a type of the selected specific content and (ii) the information on the at least one data transmission period supported by the slave device; and receiving, from the slave device, the data based on the configured specific data transmission period. The method comprises, based on the type of the selected specific content being changed, transmitting, to the slave device, a message for reconfiguring the data transmission period of the slave device based on the changed type of the content.
