Service Control Apparatus Synchronizing MTC Terminal Communication Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of Service Capability Servers (SCSs) increases, the varying communication timings between SCSs and Machine Type Communication (MTC) terminals can reduce the communication time of MTC terminals, leading to faster battery depletion due to small battery capacities in these terminals.
Innovation Solution
A service control apparatus that receives and compares communication patterns from multiple SCSs and requests the SCSs to synchronize their communication timings with the most efficient pattern, thereby reducing the overall communication time of MTC terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SCSs access one MTC terminal with different communication timings, then service coverage is improved, but communication time increases and battery life is reduced
Solution Approach 1:
The patent merges communication timing patterns from multiple SCSs by selecting one as a reference pattern and aligning other SCSs to it. This consolidation reduces redundant communications and extends battery life while maintaining service coverage from multiple SCSs.
Solution Approach 2:
The patent changes communication timing parameters (periodic communication indicator, communication duration time, periodic time, scheduled communication time) to synchronize multiple SCSs. By adjusting these parameters, the system reduces overall communication time and conserves battery energy.
2Adaptability or versatility
If multiple SCSs use different communication patterns, then service diversity is improved, but communication efficiency deteriorates
Solution Approach 1:
The patent segments communication patterns into a reference pattern and patterns to be aligned. This segmentation allows the system to maintain service diversity from multiple SCSs while improving communication efficiency through synchronized timing based on the reference pattern.
Solution Approach 2:
The patent introduces a reference communication pattern as an intermediary that mediates between multiple SCSs with different timing patterns. This intermediary enables efficient communication coordination while preserving service diversity from multiple providers.
3Use of energy by moving object
If communication timings are synchronized to reduce battery usage, then energy efficiency is improved, but flexibility in service access is reduced
Solution Approach 1:
The patent implements dynamic communication pattern alignment where SCSs can adapt their timing to match the reference pattern while still allowing for scheduled communications at different times. This dynamic approach maintains energy efficiency through synchronization while preserving necessary service access flexibility.

AI summary
A service control apparatus (20) according to the present disclosure includes: a communication unit (21) configured to receive a first communication pattern that defines a timing of communication between a service providing apparatus (30) and a communication terminal (10) from the service providing apparatus (30) and a second communication pattern that defines a timing of communication between a service providing apparatus (32) and the communication terminal (10) from the service providing apparatus (32); and a controller (22) configured to determine whether the first communication pattern and the second communication pattern indicate communication timings different from each other. When the first communication pattern and the second communication pattern indicate communication timings different from each other, the communication unit (21) transmits a message to the second service providing apparatus (32) requesting it to change its communication pattern to the first communication pattern.
