Class-Specific Registration Schedules for M2M Battery Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional timer-based registration periods in wireless communication systems are burdensome for machine-to-machine (M2M) enabled access terminals, consuming substantial battery power as they require frequent registration, which is not necessary for devices that send/receive data infrequently.
Innovation Solution
Implementing a system that allows access terminals to register based on class-specific periodic schedules, where M2M devices can use longer registration periods to conserve battery life, and enabling registration in combination with data message transmissions, allowing devices to power down and skip timer-based registrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional timer-based registration periods are used for all access terminals, then network management and tracking are maintained, but M2M devices consume substantial battery power due to frequent registrations
Solution Approach 1:
The patent applies local quality by differentiating registration requirements based on access terminal type. M2M devices are assigned extended registration periods while regular access terminals use standard periods, allowing each class to have optimized registration frequency suited to its operational characteristics and power constraints
Solution Approach 2:
The patent changes the registration period parameter from a fixed value to a variable that depends on access terminal class. The base station transmits different registration period values to different terminal types, enabling M2M devices to operate with longer intervals between registrations thereby reducing power consumption while maintaining network manageability
2Reliability
If M2M devices perform frequent timer-based registrations, then network tracking is maintained, but device battery life is reduced
Solution Approach 1:
The system applies local quality by providing differentiated treatment for M2M devices versus regular access terminals. M2M devices receive extended registration periods tailored to their infrequent data transmission patterns, allowing them to maintain network tracking capability while significantly extending battery life through reduced registration frequency
Solution Approach 2:
The patent implements periodic action with variable periods based on device class. Instead of uniform continuous registration, M2M devices perform registrations at extended periodic intervals that match their operational patterns, maintaining network tracking while minimizing power consumption during idle periods
3Reliability
If M2M devices register frequently to maintain network presence, then network management is improved, but power consumption increases
Solution Approach 1:
The patent changes the registration period parameter dynamically based on access terminal class. The base station transmits class-specific registration period values, allowing M2M devices to use extended periods that reduce the frequency of registration operations and thereby decrease overall power consumption while maintaining adequate network management
4Use of energy by moving object
If class-specific periodic registration schedules are implemented, then power consumption is reduced for M2M devices, but system complexity increases
Solution Approach 1:
The patent applies universality by creating a multi-functional registration system that handles both regular access terminals and M2M devices through a unified base station implementation. The base station performs multiple functions by transmitting class identifiers and managing different registration periods for different terminal types within the same system architecture, avoiding the need for separate systems
