Solution Overview

Problem

Communications network devices face challenges in prolonging battery usage time due to non-linear discharge characteristics and the inability to utilize battery recovery effects, leading to reduced endurance times, especially in continuous data transmission scenarios like LTE networks.

Innovation Solution

Implementing a data interval policy that divides data into segments with inserted time intervals for battery recovery, allowing network devices to communicate efficiently and reduce power consumption by determining optimal segment lengths and intervals based on task status and battery recovery information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If continuous data transmission is performed in LTE network, then communication efficiency is maintained, but battery consumption increases due to non-linear discharge characteristic

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidbattery consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent segments continuous data transmission into periodic transmission intervals with idle periods in between. The data transmission is divided into active transmission phases followed by idle phases, allowing the battery to discharge in a more linear manner and enabling recovery effects to take place during idle periods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements periodic data transmission where data is transmitted in regular intervals rather than continuously. This periodic action creates alternating active and idle states, reducing the non-linear discharge impact by allowing the battery to rest during idle periods while maintaining communication efficiency through scheduled transmissions.

Inventive Principle:
Principle #19Periodic action

2Duration of action of moving object

If data transmission duration is extended to improve communication completeness, then more data is transmitted, but battery electric quantity decreases at higher speed due to non-linear discharge

Engineering Contradiction:
Improvedata transmission durationVSAvoidbattery electric quantity loss
Core Design Contradiction:
Duration of action of moving objectVSLoss of energy

Solution Approach 1:

The patent divides extended data transmission into multiple segmented intervals with idle periods between them. Instead of one continuous long transmission, data is transmitted in segments separated by idle periods, allowing the battery to recover during gaps and reducing the accelerating discharge rate associated with prolonged continuous operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent incorporates idle periods before battery electric quantity becomes critically low, allowing the battery recovery effect to take place in advance. This preliminary resting action prevents the battery from entering severe non-linear discharge territory, ensuring sustained transmission capability.

Inventive Principle:
Principle #10Preliminary action

3Duration of action of stationary object

If battery recovery effect is utilized by inserting idle periods, then battery usage time is prolonged, but communication efficiency may be reduced due to interrupted transmission

Engineering Contradiction:
Improvebattery usage timeVSAvoidcommunication efficiency
Core Design Contradiction:
Duration of action of stationary objectVSProductivity

Solution Approach 1:

The patent dynamically adjusts the ratio of active transmission time to idle time based on communication requirements and battery status. The idle period duration and transmission interval are optimized to balance battery recovery needs with communication efficiency, allowing the system to adapt between more aggressive transmission schedules and more conservative battery-saving schedules.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes transmission parameters such as data segment size, transmission power, and idle period duration to optimize the balance between battery recovery and communication efficiency. By adjusting these parameters, the system can maintain acceptable communication performance while enabling sufficient idle time for battery recovery effects.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention discloses a low power consumption communication method. The method includes: obtaining, by a first network device, a data interval policy, where the data interval policy is determined according to a task status of the first network device, and the data interval policy includes a data segment length and an interval time between data segments; sending, by the first network device, the data interval policy to the second network device; and sending, by the first network device, data to the second network device according to the data interval policy or receiving data that is sent by the second network device according to the data interval policy. By means of the technical solutions in the present invention, an electric quantity can be recovered in an interval time between data segments by using a battery recovery effect, thereby reducing electricity consumption during communication, and prolonging a usage time of a battery of a network device. Because the data interval policy for saving an electric quantity of a battery of the second network device is formulated by the first network device, adaptability of the communication method is enhanced.
