Group Paging for M2M Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine-to-machine communication in advanced wireless systems like IEEE 802.16 and 3GPP faces network congestion due to the need for individual communication with a large number of devices, which is inefficient and leads to traffic congestion.
Innovation Solution
A group-based paging method where M2M-capable base stations group devices with similar traffic properties, assign them a group ID, and page them collectively using a paging channel, reducing the overhead on the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual communication with each M2M device is implemented, then device-specific communication is achieved, but network congestion occurs due to the large number of devices
Solution Approach 1:
The patent combines multiple individual device paging operations into a single group paging operation. Devices with similar traffic patterns are grouped together and assigned a common group ID, allowing the base station to page an entire group simultaneously rather than individually, thus reducing network congestion while maintaining device-specific communication capability.
Solution Approach 2:
The patent segments the large population of M2M devices into smaller groups based on traffic properties. Each group is assigned a unique group ID, and the base station can selectively page specific groups rather than all devices individually. This segmentation reduces the paging overhead and network congestion.
2Quantity of substance
If a large number of M2M devices are supported, then Internet of Things potential is realized, but network traffic congestion increases due to numerous interactions
Solution Approach 1:
The patent merges multiple device identifiers into group-level identifiers. Instead of generating paging traffic for each individual device, the base station pages groups of devices using a single group ID. This merging approach allows support for a large number of devices while significantly reducing the volume of paging traffic on the network.
Solution Approach 2:
The patent changes the paging parameter from individual device IDs to group IDs. By transforming the identification parameter from device-specific to group-level, the system can support exponentially more devices without proportionally increasing network traffic, as one group ID can represent multiple devices.
3Productivity
If group-based paging is implemented, then network congestion is reduced, but devices with different traffic properties may be grouped together
Solution Approach 1:
The patent applies local quality by creating groups with homogeneous traffic characteristics. Each group is formed based on specific traffic properties (such as traffic pattern, data rate requirements, or service type), ensuring that devices within the same group have similar communication needs. This allows the paging mechanism to be adapted to different traffic requirements while maintaining network efficiency.

AI summary
A group paging method is disclosed for efficient machine-to-machine communication in a wireless network. The group paging method enables M2M-capable base stations to group M2M- capable mobile stations according to their traffic properties, assign them a group paging ID, and thereafter page the M2M device, whether the mobile station is asleep or not, by way of a paging channel. The group paging method mitigates traffic congestion on the wireless network.
