M2M Group Paging via MGID for Signaling Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional idle mode operations in mobile communication networks are not optimized for machine-to-machine (M2M) devices, leading to inefficient power consumption and increased signaling burden during location updates.
Innovation Solution
A method and device for M2M communication that allows paging in group units using a dynamic service addition message with a M2M Group Identifier (MGID), enabling location updates by transmitting a ranging request and responding with a new MGID, thereby reducing signaling burden and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional idle mode operation is used, then power consumption is reduced, but location update efficiency and signaling management are not optimized for M2M devices
Solution Approach 1:
The patent segments M2M devices into groups identified by M2M Group Identifiers (MGID), allowing the network to manage location updates at the group level rather than individually. This segmentation enables efficient paging of multiple devices simultaneously while maintaining low power consumption for individual devices, resolving the contradiction between power savings and location update efficiency.
Solution Approach 2:
The patent combines multiple M2M devices into a single paging group that can be addressed together through a single paging message. By merging device management at the group level, the system achieves both low power consumption (devices remain in idle mode) and high location update efficiency (group-based updates), eliminating the trade-off present in conventional individual device management.
2Ease of operation
If individual device paging is used, then device-specific control is achieved, but signaling burden increases for M2M devices
Solution Approach 1:
The patent merges multiple individual device control operations into a single group-based paging mechanism. Instead of sending separate paging messages to each device, the network sends a single paging message containing multiple MGIDs, significantly reducing signaling burden while maintaining the ability to control specific device groups.
Solution Approach 2:
The patent creates a universal paging mechanism that can address multiple devices simultaneously through the MGID structure. This multi-functional paging approach serves both individual device control needs and group management, reducing overall signaling complexity while maintaining operational flexibility.
3Device complexity
If group-based paging is implemented, then signaling burden is reduced, but device complexity in managing MGID increases
Solution Approach 1:
The patent implements self-service by having the network automatically assign and manage MGIDs without requiring manual configuration at M2M devices. Devices simply receive and respond to paging messages containing their assigned MGID, eliminating complex local management while reducing overall signaling burden through group-based operations.
Solution Approach 2:
The patent changes the fundamental parameter of device identification from individual device identifiers to group-based MGIDs. This parameter change simplifies signaling by allowing single message delivery to multiple devices while the network handles the complexity of MGID allocation and management centrally.

AI summary
Provided are a method and device for M2M (Machine To Machine) communication. A M2M device receives a DSA (dynamic service addition) message from a base station, and the DSA message includes an MGID (M2M Group identifier) related to an M2M multicast service. The M2M device receives a paging advertisement (PAG-ADV) message from the base station in an idle mode, and the PAG-ADV message includes the MGID and an action code directing a location update performance. The M2M device transmits a ranging request (RNG-REQ) from the base station to perform a location update.
