Flexible Profile Grouping for MTC Device Data Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for managing Machine Type Communication (MTC) devices in cellular networks face challenges such as network overload due to increased signaling, inefficient data transfer, and excessive data volume, particularly when updating or changing device profiles across multiple devices.
Innovation Solution
A method and system for efficient data provisioning that involves a central database providing group data to local databases, allowing flexible profile grouping and reducing redundant data transfers by sending group data only once and using group identifiers for efficient data management, thereby minimizing signaling overload and storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If profile data is downloaded to each device individually from the central database, then each device can access its profile data, but the signaling volume and data transfer load increase dramatically
Solution Approach 1:
The patent merges profile data from multiple devices into a single group profile when the data is identical. Instead of maintaining separate profile records for each device, the system consolidates common profile information into one group-level record, thereby reducing the amount of data that needs to be transferred and stored while ensuring all devices can still access their required profile data.
Solution Approach 2:
The group profile serves multiple devices simultaneously, making a single profile record universal for all members of the group. This multi-functional approach allows one profile to fulfill the data needs of numerous devices, eliminating redundant data transfers and reducing signaling volume while maintaining data availability for each device.
2Quantity of substance
If group data is cached in local databases, then data transfer volume is reduced, but storage requirements and data synchronization complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-identifying and grouping devices with identical profile data before data transfer occurs. By proactively organizing devices into groups based on their profile characteristics, the system prepares the data structure in advance, enabling efficient bulk transfers and eliminating the need for complex real-time synchronization during data updates.
Solution Approach 2:
Local databases automatically cache group profile data and perform self-updates when changes occur, without requiring complex centralized coordination for each individual update. The system enables local databases to serve themselves by providing mechanisms for automatic data retrieval and caching, reducing the synchronization burden on the central system.
3Stability of the object's composition
If all devices in a group receive profile updates simultaneously, then data consistency is maintained, but network overload increases
Solution Approach 1:
The patent merges multiple identical profile update operations into a single group-level update. Instead of sending separate update messages to each device, the system consolidates the update into one group profile modification, which is then distributed to all group members simultaneously, maintaining data consistency while reducing the total data volume transmitted across the network.
4Adaptability or versatility
If individual device profiles are maintained in the central database, then device-specific customization is enabled, but provisioning and storage resources are consumed inefficiently
Solution Approach 1:
The patent segments profile data into two distinct parts: group-level common data and device-specific customizations. This segmentation allows the system to efficiently manage and provision the common portion at the group level while maintaining the ability to customize individual device profiles when needed, thereby improving provisioning efficiency without sacrificing adaptability.
Solution Approach 2:
The group profile acts as a universal template that can be applied to multiple devices, enabling efficient bulk provisioning. This universal approach allows the system to provision numerous devices simultaneously using a single profile configuration, significantly improving productivity while still allowing individual customization when specific devices require unique settings.

AI summary
A method for providing of data is provided, the method comprising at a first database: providing of group data; providing of data of a first entity, in particular of a first device, the data of the first entity comprising the group data; receiving from a second database a request for the data of the first entity; determining that the data of the first entity comprises the group data and that said group data has not been sent to the second database before; and if said determining step is in the affirmative, sending the data of the first entity comprising the group data to the second database.
