Embodiment Construction

[0025] figure 1 The flow chart of the method for ending a call provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes:

[0026] Step 101. If the distance between the mobile terminal and the obstruction is greater than a preset first threshold N, calculate a change value between the current posture of the mobile terminal and the initial posture.

[0027] Wherein, the distance between the mobile terminal and the blocking object can be detected by a proximity sensor. The proximity sensor may be located near the earpiece on the front of the phone. In this embodiment, the blocking object may be any object close to the proximity sensor of the mobile terminal. The distance between the mobile terminal and the shield can be measured by a proximity sensor preset inside the mobile terminal. What needs to be explained here is that the proximity sensor can detect a certain distance, and this detection distance has different values ​​according ...

Abstract

The invention provides a method and a device for ending a conversation. The method comprises the following steps: if the distance between a mobile terminal and a shielding object is more than a preset first threshold value N, calculating a change value between the current gesture and initial gesture of the mobile terminal; if the change value continuously exceeds a second threshold value M within a first preset time period A, detecting a difference value between the input volume of the mobile terminal and a measured environment base value; and if an average value of the difference value is less than a third threshold value V within a second preset time period B, ending the conversation. The device comprises an approaching distance sensor, a gravity inductive sensor, a CPU (Central Processing Unit) and a memory. According to the scheme provided by the invention, the change in the distance between the mobile terminal and the object, the change in the gesture of the mobile terminal and the change in the input volume of the mobile terminal are utilized to judge whether to end the conversation, and the judgment accuracy is efficiently ensured.

Description

technical field [0001] The invention relates to detection technology, in particular to a method and device for ending a call. Background technique [0002] After some users use the mobile terminal to make a call, the call cannot be ended due to misoperation and other reasons, which will lead to an increase in the cost of the call and cause unnecessary losses to the user. [0003] In view of the above-mentioned problem, at least two methods for ending a call are provided in the prior art. [0004] One of them is Voice Activity Detection (VAD for short) technology. This VAD technology can judge whether the call needs to be automatically terminated according to whether the duration of the inactive sound frame in the call between the two parties exceeds a preset time. The inactive sound frame specifically refers to the sound (Inactive Voice) of a pause in the conversation between the two parties or background noise during the call. However, the VAD technology is not applicabl...
