Modem Heartbeat Agent for Mobile Terminal Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for sending heartbeat messages in mobile terminals require both the application processor and modem to be active, leading to high power consumption and reduced standby time due to the need for frequent periodic wake-ups.
Innovation Solution
Implementing the push agent on the modem, allowing the modem to send heartbeat messages without waking up the application processor, thereby reducing power consumption by only using the modem's power during heartbeat message transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application processor is woken up to send heartbeat messages, then the persistent connection can be maintained, but the power consumption increases and standby time decreases
Solution Approach 1:
The patent extracts the heartbeat message sending function from the application processor and relocates it to the modem. The modem independently handles heartbeat message transmission without requiring the application processor to be woken up, thereby maintaining the persistent connection while reducing power consumption during standby mode.
2Reliability
If both application processor and modem are activated for heartbeat sending, then the connection reliability is ensured, but the device complexity and power consumption increase
Solution Approach 1:
The patent separates the heartbeat sending functionality from the application processor and assigns it exclusively to the modem. This extraction simplifies the system operation during standby by activating only the modem rather than both components, reducing the complexity of hardware coordination while maintaining connection reliability.
3Reliability
If heartbeat messages are sent periodically, then the persistent connection is maintained, but the average standby power consumption increases
Solution Approach 1:
The patent moves the periodic heartbeat sending task from the power-hungry application processor to the lower-power modem. The modem can execute the periodic heartbeat transmissions with minimal power consumption, maintaining the persistent connection while significantly reducing the average standby power consumption of the terminal.

AI summary
A method for sending a heartbeat message and a mobile terminal are disclosed. The method includes determining, according to a heartbeat message sending period, a first time point at which a heartbeat message needs to be sent; before the first time point arrives, determining whether a push message has been received to obtain a first determining result; and when the first determining result is no and the first time point arrives, waking up the modem to send a heartbeat message to a service push server. Using the method or the mobile terminal of the present disclosure, power consumption for sending a heartbeat message by a terminal may be reduced, and further average standby power consumption of the terminal may be reduced, thereby prolonging a standby time of the terminal.
