Relay Device Aggregating MTC Terminal Data to Reduce Network Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of MTC terminals in each cell leads to a significant increase in network load due to the exchange of control information, which is further exacerbated by the introduction of relay devices, necessitating measures to mitigate this load.
Innovation Solution
A relay device with a receiving unit, storage unit, and transmitting unit that aggregates and processes information from multiple wireless communication devices, including MTC terminals, to efficiently manage and transmit data to a base station, thereby reducing network load through intermittent aggregation and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay devices are introduced to extend coverage and accommodate MTC terminals, then the number of accessible terminals is improved, but the network load increases due to doubled links and increased control information exchange
Solution Approach 1:
The patent merges multiple small data packets from different MTC terminals into a single aggregated data structure called a data container. This container includes a container ID, sequence number, and multiple data elements, each associated with a specific terminal. By combining multiple transmissions into one aggregated message, the system reduces the number of individual control information exchanges between relay devices and base stations, thereby mitigating network load while maintaining coverage extension capability
Solution Approach 2:
The relay device performs preliminary aggregation of data from multiple terminals before forwarding to the base station. The data container is prepared in advance with all necessary information (container ID, sequence number, data elements with terminal identifiers) organized in a structured format. This preliminary organization reduces the processing burden and control information exchange required at the base station, effectively reducing network load before data reaches the core network
2Quantity of substance
If the number of links is increased to accommodate more MTC terminals, then the terminal capacity is improved, but the amount of control information such as scheduling and authentication settings increases
Solution Approach 1:
The patent combines control information for multiple terminals into a single aggregated data container that is efficiently processed. Instead of exchanging separate control messages for each terminal's scheduling and authentication, the system uses a unified container structure that carries multiple data elements, each with terminal-specific information. This merging approach maintains terminal capacity while significantly reducing control information overhead
Solution Approach 2:
The patent changes the parameter of data transmission from individual terminal-based messages to aggregated container-based messages. The data container introduces new parameters (container ID, sequence number, data element structure) that enable efficient grouping and identification of multiple terminals' data. This parameter transformation allows the system to maintain support for many terminals while reducing the overall volume of control information required
