MTC Terminal Low Power Communication Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine type communication (MTC) terminals face significant challenges in achieving battery life beyond several months due to high power consumption, particularly in idle states, data synchronization, intercepting control channels, transmitting uplink data, and receiving downlink data, making it difficult to maintain communication for extended periods.
Innovation Solution
A communication method for MTC terminals that involves sending a wireless channel request message through a random access channel, receiving an immediate assignment message, and transmitting an MTC data report message with a unique identifier, authentication information, and service data, optimizing power consumption by using a base station and base station controller to allocate data transmission resources and manage terminal operations.

Engineering Contradiction Analysis
1Duration of action of moving object
If existing communication methods are used for MTC terminals, then the terminal can maintain communication functionality, but the battery life will not exceed several months due to high power consumption
Solution Approach 1:
The patent extracts and eliminates unnecessary signaling data transmission and reception processes from the GPRS communication method. By removing redundant uplink and downlink signaling exchanges, the terminal reduces its active communication time and power consumption, enabling battery life to extend from months to years while maintaining essential communication functionality.
Solution Approach 2:
The patent implements preliminary action by having the terminal send channel request messages and receive immediate assignment messages before actual data transmission is needed. This allows the terminal to efficiently allocate resources and minimize active communication time, reducing overall power consumption while ensuring communication readiness when needed.
2Reliability
If the terminal frequently synchronizes and intercepts control channel information, then the terminal can maintain up-to-date communication status, but power consumption increases significantly
Solution Approach 1:
The patent applies periodic action by reducing the frequency of synchronization and control channel interception operations. Instead of continuous or frequent updates, the terminal performs these operations at optimized intervals, maintaining adequate communication status accuracy while dramatically reducing the power consumption associated with these activities.
3Reliability
If the terminal transmits and receives extensive signaling data, then the terminal can maintain proper communication protocols, but battery life is limited to half a year or less
Solution Approach 1:
The patent extracts and removes unnecessary signaling data transmission and reception from the communication process. By eliminating redundant protocol exchanges while retaining essential protocol compliance, the terminal reduces communication activity and extends battery life from half a year or less to several years.
