detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a method for monitoring a call mode. Referring to FIG. 1, the method includes:

Step S11: If the current communication terminal performs a call in the RCS mode, the real-time remaining power of the communication terminal is obtained.

That is, in the present embodiment, in the case where the current communication terminal is making a call with the outside world in the RCS mode, the real-time remaining power of the communication terminal is acquired in real time. It can be understood that the embodiment of the present invention needs to perform real-time monitoring on the communication terminal to determine whether the current communication terminal is conducting a call in the RCS mode. Once the communication terminal is detected to be in the RCS mode, the real time of the communication terminal is acquired. remaining battery.

Step S12: It is determined in real time whether the real-time remaining power of the communication terminal is less than or equal to the first preset power threshold. If yes, the process goes to step S13, and if no, the process goes to step S14.

It should be noted that the first preset power threshold may be specifically set based on actual application requirements, for example, may be set to 15%. Moreover, it should be further noted that the setting of the first preset power threshold may be manually set, or may be set by default by the background system of the communication terminal.

Step S13: Switch the communication mode of the communication terminal from the RCS mode to the CS mode (CS, that is, Circuit Switched, circuit switching).

That is, in the case that the real-time remaining power of the communication terminal is less than or equal to the first preset power threshold, the embodiment switches the communication mode of the communication terminal from the RCS mode to the CS mode, because the CPU of the communication terminal is in the CS mode. In the standby state, when the communication mode of the communication terminal is switched to the CS mode, the power consumption speed of the communication terminal will be greatly reduced, thereby greatly prolonging the call duration and improving the user experience.

For example, if the first preset power threshold is 15% in this embodiment, in this embodiment, if the remaining power of the current communication terminal is 18%, if the user turns on the RCS mode at this time, During the call, the power of the communication terminal will drop rapidly during the call. When it is reduced to 15%, the communication mode of the communication terminal will be switched from the RCS mode to the CS mode, thereby entering the low power consumption mode.

As another example, if the first preset power threshold is 15% in this embodiment, in this embodiment, if the remaining power of the current communication terminal is 14%, if the user does not notice the current The power is at a low power level, and the RCS mode is forcibly turned on to make a call. The technical solution in this embodiment will immediately detect that the real-time remaining power (14%) of the current communication terminal is less than 15%, so this embodiment will immediately Switching the RCS mode to CS mode enters the low power mode.

Step S14: Continue to maintain the communication mode of the communication terminal in the RCS mode.

That is, in the case where the current remaining power of the communication terminal is large, the communication mode of the communication terminal is continuously maintained in the RCS mode, thereby enabling the user to enjoy a better call service.

It can be seen that, in the embodiment of the present invention, when the current communication terminal is in the RCS mode, the real-time remaining power of the communication terminal is obtained in real time, and the real-time remaining power of the communication terminal is determined to be less than or equal to the first preset power threshold. When it is determined that the real-time remaining power of the communication terminal is less than or equal to the first preset power threshold, the call mode of the communication terminal is switched from the original RCS mode to the CS mode, and the CPU of the communication terminal in the CS mode is in the standby state. Therefore, when the communication mode of the communication terminal is switched to the CS mode, the power consumption speed of the communication terminal will be greatly reduced, thereby greatly prolonging the call duration and improving the user experience. That is, the embodiment of the present invention achieves the purpose of avoiding the rapid exhaustion of the power of the communication terminal due to excessive power consumption when the communication terminal is making a call in the RCS mode.

If the real-time remaining power of the communication terminal is reduced to the second preset power threshold, the first battery prompt information is generated; wherein the second preset power threshold is smaller than the first preset power threshold; and then the first power prompt is played on the communication terminal. information.

For example, in this embodiment, the second preset power threshold may be specifically set based on actual application requirements, for example, may be set to 5%. Moreover, it should be further noted that the setting of the second preset power threshold may be manually set, or may be set by default by the background system of the communication terminal.

It can be understood that after the communication terminal plays the first power prompt information, the user of the communication terminal will know that the current communication terminal is almost exhausted. In this case, the user of the communication terminal may consciously select the communication terminal. Perform a charging operation. In this embodiment, the first power prompt information may be voice information, and may be voice information such as “the current power of your mobile phone is only 5%, please charge in time or end the call as soon as possible”.

In this embodiment, after the process of switching the communication mode of the communication terminal from the RCS mode to the CS mode, the method further includes:

When the real-time remaining power of the communication terminal falls to the second preset power threshold, the second battery prompt information is generated; then, the second battery prompt information is sent to the other terminal currently talking with the communication terminal to play on the other terminal. The second battery prompt message.

It can be understood that after the second terminal plays the second power prompt message, the user of the counterpart terminal will know that the power of the communication terminal is running out, which is beneficial to the user of the counterpart terminal consciously ending the call as soon as possible, or with the above communication terminal. The user re-receives the talk time, thereby avoiding unwarranted suspicion or confusion to the user of the other terminal due to sudden power failure of the communication terminal and sudden interruption of the call. In this embodiment, the second power prompt information may specifically be voice information, and specifically may be “voice information of only 5% of the current mobile phone, please remind the other party to charge in time or end the call as soon as possible”.

In addition, after the process of switching the communication mode of the communication terminal from the RCS mode to the CS mode, the method in this embodiment may further include:

That is, after the current call mode of the communication terminal is switched to the CS mode, the communication terminal will be monitored in real time to determine whether the communication terminal enters the charging state. If the communication terminal is detected to enter the charging state, it means the current communication terminal. The power is sufficiently guaranteed, so that the communication mode of the communication terminal can be switched from the CS mode to the RCS mode, so that the user can enjoy a better call service.

In addition, in this embodiment, before the process of determining whether the real-time remaining power of the communication terminal is less than or equal to the first preset power threshold, the method further includes:

A first power threshold input interface is created on the human-machine interface of the communication terminal, and then the power threshold input by the user through the first power threshold input interface is determined as the first preset power threshold.

That is, the first preset power threshold in this embodiment can be customized by the user, which is beneficial to improving the user experience.

Further, in this embodiment, the process of switching the communication mode of the communication terminal from the RCS mode to the CS mode may include: automatically switching the communication mode of the communication terminal from the RCS mode to the CS mode. It can be understood that, in the embodiment, when the call mode is automatically switched, the automatic switching may be performed instantaneously, or the automatic switching may be performed after a preset time period elapses, for example, automatic switching in the background after 5 seconds elapse.

Of course, in addition to the automatic switching, the embodiment may also be manually switched. Correspondingly, the foregoing process of switching the communication mode of the communication terminal from the RCS mode to the CS mode includes:

Generating a call mode switching interface on the human-computer interaction interface of the communication terminal, and then using the call mode switching interface to obtain a corresponding user instruction. If the user instruction is a handover confirmation command, the communication mode of the communication terminal is switched from the RCS mode to the CS mode. .

It can be understood that when the above user command is a handover rejection command, the communication mode of the communication terminal will continue to be maintained in the RCS mode.

Correspondingly, the embodiment of the present invention further discloses a call mode monitoring system. Referring to FIG. 2, the system includes:
