M2M Device SCI Configuration for Battery Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Slot Cycle Index (SCI) configuration and timer assignment methods for Machine-to-Machine (M2M) communications and general-purpose Mobile Stations (MS) are not differentiated, leading to inefficient battery power management and unnecessary resource usage, as they are applied uniformly without considering the distinct communication patterns of M2M devices.
Innovation Solution
Separate configuration of SCI for M2M devices and general-purpose MS, and separate assignment of timers to optimize power consumption and resource utilization based on the specific communication needs of each, allowing M2M devices to monitor paging channels and receive overhead messages according to their unique service types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform SCI configuration is applied to both general-purpose MS and M2M devices, then general-purpose voice service reliability is maintained, but M2M device battery consumption increases unnecessarily
Solution Approach 1:
The patent segments the SCI configuration into two distinct sets: one for general-purpose MS devices and another for M2M devices. The network separately configures and assigns appropriate SCI values based on device type, allowing M2M devices to use longer slot cycles optimized for their delay-tolerant applications, thereby reducing their battery consumption while maintaining voice service reliability for general-purpose devices.
Solution Approach 2:
The patent applies local quality by tailoring the SCI configuration to the specific characteristics of each device type. M2M devices receive customized SCI settings matched to their delay-tolerant communication patterns, while general-purpose MS devices receive configurations optimized for real-time voice services. This localized optimization ensures each device type operates with energy efficiency appropriate to its functional requirements.
2Reliability
If uniform timer assignment is used for both general-purpose MS and M2M devices, then system information reception is ensured for voice services, but resource utilization efficiency decreases
Solution Approach 1:
The patent segments timer assignment into device-type-specific configurations. The network assigns different timer values to general-purpose MS devices and M2M devices based on their respective communication patterns. M2M devices receive longer timer intervals matching their infrequent communication needs, reducing unnecessary wake-ups and resource usage, while general-purpose devices maintain shorter timers for timely voice service reception.
Solution Approach 2:
The patent applies partial action by assigning timer values that are precisely matched to each device type's actual needs rather than using a uniform excessive timer for all devices. M2M devices receive partial timer assignments optimized for their low-activity patterns, avoiding the resource waste of frequent wake-ups, while general-purpose devices receive sufficient timer assignments to ensure reliable voice service reception.
3Speed
If M2M devices use frequent paging channel monitoring, then incoming communications are received promptly, but battery power is depleted rapidly
Solution Approach 1:
The patent applies dynamics by making the paging channel monitoring frequency adaptive to the device type and service requirements. M2M devices dynamically adjust their monitoring frequency based on their delay-tolerant nature, using longer intervals between monitoring cycles. This dynamic adjustment reduces their battery power consumption significantly while still maintaining acceptable response times for their specific application requirements.
Solution Approach 2:
The patent implements periodic action with customized intervals for different device types. M2M devices perform paging channel monitoring at extended periodic intervals appropriate for their infrequent communication patterns, rather than continuous or frequent monitoring. This periodic approach with optimized intervals maintains communication reliability for M2M applications while dramatically reducing their battery power consumption.

AI summary
A mobile communication device configured for Machine-to-Machine (M2M) communications is provided. In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a service network, and a controller module receives a message with a Slot Cycle Index (SCI) only for the M2M communications from the service network via the wireless module and instructs the wireless module to monitor a paging channel according to the SCI only for the M2M communications.
