M2M Device Group Identifier Collision Resolution via Zone Index Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In M2M communication systems, base stations being part of multiple M2M device group zones lead to collisions of M2M device group identifiers, causing signaling messages intended for one group to reach devices from another group with the same identifier, resulting in incorrect message processing.
Innovation Solution
A method and apparatus that determine zone indexes corresponding to zone identifiers and use a M2M device group identifier in conjunction with a zone index to uniquely identify the intended M2M device group, ensuring accurate message transmission and reception by M2M devices and base stations operating across multiple M2M device group zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base stations are made part of multiple M2M device group zones to avoid frequent identifier updates during device mobility, then device mobility handling is improved, but identifier collision occurs between devices from different zones
Solution Approach 1:
The solution segments the identifier space by introducing a zone index component that divides the previously unified MGID into a composite identifier structure. This segmentation allows the same MGID to be uniquely associated with different zones through distinct zone indexes, resolving the collision problem while maintaining multi-zone base station functionality.
Solution Approach 2:
The patent adds a new dimension (zone index) to the identifier system. Instead of relying solely on the MGID, the system now uses a two-dimensional identifier space comprising zone index and MGID pairs. This dimensional expansion enables unique identification across multiple zones without restricting base station participation in multiple zones.
2Measurement precision
If M2M device group identifier is updated when device moves between zones, then identifier accuracy is maintained, but frequent updates occur at zone boundaries causing signaling overhead
Solution Approach 1:
The system performs preliminary action by pre-configuring base stations with multiple zone indexes corresponding to different M2M device group zones. When a device moves to a base station, the device and base station can directly use the appropriate pre-configured zone index without requiring identifier updates, eliminating the need for frequent signaling exchanges at zone boundaries.
Solution Approach 2:
The zone index acts as an intermediary that resolves the conflict between device mobility and identifier accuracy. Instead of updating the MGID when devices move between zones, the zone index mediates by providing zone-specific context, allowing the same MGID to be accurately associated with different zones through the intermediary zone index mechanism.
3Productivity
If base station serves multiple M2M device group zones, then network coverage and device connectivity are improved, but signaling messages may reach wrong device groups due to identifier collision
Solution Approach 1:
The solution applies local quality by making the identifier system zone-specific. Each zone has its own zone index that locally qualifies the MGID, ensuring that identifier interpretation is adapted to the local zone context. This allows base stations to serve multiple zones with different local identifier qualities, preventing message misdelivery while maintaining broad connectivity.

AI summary
A method and a system apparatus for providing Machine to Machine (M2M) communications in a multiple M2M device group zone environment are provided. The method for performing communication by an M2M device in an M2M communication system includes determining zone indexes corresponding to one or more zone identifiers assigned to one or more M2M device group zones of the base station, selecting a zone index corresponding to a zone identifier of the M2M device group zone associated with a M2M device group of a M2M device from the determined zone indexes, and performing communication with the base station by using the selected zone index and a M2M device group identifier associated with the M2M device group of the M2M device.
