Solution Overview

Problem

In electronic devices operating on 5G networks, high power consumption leads to heat generation, which can cause freezing or disconnection when the device switches to a 4G network to cool down, due to increased latency, affecting user experience.

Innovation Solution

The method involves monitoring network latencies and temperatures to determine a network handover policy, adjusting fluency parameters like frame rate or resolution, and prioritizing networks based on latency to prevent freezing or disconnection.

Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring of temperature and network performance metrics, with scheduled evaluations of handover conditions. This periodic assessment allows the device to maintain optimal 5G performance while periodically checking whether thermal thresholds require network transitions for cooling

Inventive Principle:

Solution Approach 1:

The system introduces network handover as an intermediary mechanism between thermal management requirements and user experience preservation. Instead of directly reducing fluency parameters to control temperature, the system uses network switching as an intermediate approach that addresses thermal issues while maintaining acceptable user experience through optimized network selection

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of this application provide a method for adjusting interface balance and an electronic device, to resolve a conventional-technology problem that when the electronic device is cooled down, freezing or even disconnection may occur on an interface of the electronic device. The method includes: In response to an operation of enabling a first data service by a user, the electronic device detects a current network. If the current network is a first network, the electronic device obtains a first service latency of running the first data service in the first network by the electronic device, and continuously monitors a first temperature of the electronic device. When the first temperature is greater than a first preset temperature, the electronic device triggers handover from the first network to a second network, and obtains a second service latency of running the first data service in the second network by the electronic device, where network performance of the first network is higher than network performance of the second network. The electronic device determines a network handover policy based on the first service latency and the second service latency.
