For the embodiment of the application, according to the signal intensity corresponding to at least one available signal source, determining the available signal source with the highest signal intensity from the at least one available signal source as a target signal source, and enabling the target device to conduct video call based on the target signal source. When the signal is poor, the target device frequently transmits identification information to the signal source to determine the signal source, resulting in increased power consumption, therefore, the frequency of switching signals of the target equipment is reduced by enabling the target equipment to be connected with the signal source with higher signal strength to carry out video call, and the power consumption of the target equipment caused by searching the signal source is reduced.

Further, in different power intervals, the use priority of video call using each available signal source may be different, and the use priority may be determined according to the power consumption and call quality of video call using each available signal source by the target device. For different electric quantity intervals, the weight of the electric consumption and the conversation quality is different, for example, the electric quantity intervals comprise a low electric quantity interval, a medium electric quantity interval and a high electric quantity interval, and when the electric quantity interval is the low electric quantity interval, the weight ratio of the electric consumption to the conversation quality is 8:2; when the electric quantity interval is a medium electric quantity interval, the weight ratio of the power consumption to the conversation quality is 5:5; when the electric quantity interval is a high electric quantity interval, the weight ratio of the power consumption to the conversation quality is 3:7.

Specifically, according to the signal intensity and the use priority corresponding to at least one available signal source, comprehensively analyzing the suitability of each available signal source, wherein the greater the signal intensity is, the higher the suitability of the available signal source with higher use priority is, and then the available signal source with the highest suitability is selected from the available signal sources as the target signal source. The method can be used for distributing preset weight coefficients to the signal intensity and the use priority, calculating the comprehensive evaluation value of each available signal source, and further determining the available signal source with the highest comprehensive evaluation value as the target signal source.
Determining the use priority corresponding to at least one available signal source according to the residual electric quantity of the target equipment, wherein the priority order of video call carried out by using each available signal source is possibly different under the condition of different electric quantities; when the remaining power is low, the priority of use of the available signal sources with less power consumption may be higher. And further, according to the use priority and the signal intensity of each available signal source, comprehensive analysis is performed, and a target signal source is determined from at least one available signal source, so that the video call effect is better by using the determined target signal source.
Further, before starting the video call, if the signal intensity of each available signal source in the target area where the target device is located is not good, the user may be prompted to go to an area with high signal intensity to perform the video call, so that the video call method further includes step SA1 (not shown in the figure) -step SA3 (not shown in the figure), where:

The distance may be a shortest linear distance between the current position of the target device and the target coverage area, or a shortest route distance between the current position of the target device and the target coverage area.
And step SA3, determining and outputting first prompt information based on the target signal point.
