It is to be understood that the terms "first," "second," and the like as used herein may be used herein to describe various terminals, but these terminals are not limited by these terms. These terms are only used to distinguish a first terminal from another terminal. For example, a first terminal may be termed a second terminal, and, similarly, a second terminal may be termed a first terminal, without departing from the scope of the present application. The first terminal and the second terminal are both terminals, but they are not the same terminal.

In one embodiment, as shown in fig. 2, a call atmosphere generation method is provided, which is described by taking the method as an example applied to the first terminal 102 in fig. 1, and includes the following steps:

step 202, a call request is sent.

Wherein the call request is for transmission to a called party, and the session connection is established based on the communication network. The call request may be made by dialing through a dialer on the terminal, or by voice dialing, and the manner of generating the call request is not limited herein.

Specifically, a calling party and a called party communicate with each other, and a call request is sent to the called party through a dialer or voice dialing on a terminal based on a communication network. The communication mode is not limited to voice communication, but may also be audio/video communication, etc.

And step 204, responding to a theme setting instruction triggered on the call interface corresponding to the call request, and switching to the theme interface corresponding to the theme setting instruction.

The theme setting instruction is used for setting a theme of session connection established based on the call request, wherein the theme of session connection provides a conversation atmosphere when the session is connected, and the atmosphere can be quiet, easy, melancholy, romantic and the like. The theme setting instruction should not be limited to be generated by a user triggering on a call interface, but may be generated by other methods such as timer timing triggering.

The theme interface can display theme selection functions, the theme interface can include different types of themes, different theme types can be displayed on the theme interface in a list form or a picture and text combination form, one theme corresponds to at least one type of background music, the background music is music or audio content provided during a call, and the background music can provide relaxing, friendly or other specific types of atmospheres for voice call participants; the theme interface can also display a sound control function, a preset filtering function and the like, wherein the sound control function is to detect the loudness of the background music in real time through the sound module, control the loudness of the background music through negative feedback adjustment, and reduce the loudness of the background music through negative feedback adjustment when the negative feedback adjustment is used for detecting that the loudness of the background music is greater than the preset loudness, so as to realize the automatic control and adjustment of the background music.

Specifically, when responding to a triggered theme setting instruction on a call interface corresponding to a call request, the first terminal 102 switches to the theme interface corresponding to the theme setting instruction, where the switching manner may be to pop up the theme interface corresponding to the theme setting instruction on the call interface, or to suspend the theme interface corresponding to the theme setting instruction on the call interface.

In an embodiment, after the first terminal 102 sends the call request, the timer is triggered to start timing, when the timing time of the timer is equal to the preset time, the theme setting on the call interface is triggered to generate a theme setting instruction, and the first terminal 102 switches to the theme interface corresponding to the theme setting instruction in response to the theme setting instruction corresponding to the call request, where the switching manner may be to pop up the theme interface corresponding to the theme setting instruction on the call interface or to suspend the theme interface corresponding to the theme setting instruction on the call interface. The timer is used for triggering at fixed time, so that the triggering operation can be reduced, and the theme setting is facilitated.

And step 206, responding to the theme selection instruction triggered on the theme interface, and acquiring background music corresponding to the theme selection instruction.

The theme selection instruction is used for selecting background music corresponding to a theme, and the theme of one theme type may correspond to a plurality of pieces of background music, for example, the background music corresponding to the theme of a quiet type includes: background music 1, background music 2, background music 3, background music 4, etc. The background music may be acquired from the local memory of the first terminal 102, or may be acquired from the cloud memory by connecting to the cloud through an interface, and the manner of acquiring the background music is not limited.

In one embodiment, the first terminal responds to a theme setting instruction triggered on a call interface corresponding to the call request, and switches to a theme interface corresponding to theme setting, wherein the theme interface can comprise a predefined theme and a self-defined theme, and the self-defined theme is that a user defines the theme according to actual requirements and selects corresponding background music; and responding to a theme selection instruction triggered on the theme interface, and acquiring background music corresponding to the theme selection instruction from a local memory or a cloud storage.

And step 208, acquiring the call voice of the calling party, and sending the background music and the call voice of the calling party to the called party corresponding to the call request.

Specifically, the first terminal 102 obtains the call voice of the calling party through the voice unit, processes the call voice, processes the processed call voice and the background music through digital signal processing to obtain a digital signal corresponding to the call voice and a digital signal corresponding to the background music, and sends the obtained digital signal of the call voice and the obtained digital signal of the background music to the called party corresponding to the call request; the processing method for processing the call voice is not limited to filtering the call voice.

Step 210, receiving the called party's call voice sent by the called party, and playing the background music and the called party's call voice.

Specifically, a session connection is established based on a call request, the first terminal receives the call voice of the called party sent by the called party, triggers a loudspeaker, and plays background music and the received call voice of the called party through the loudspeaker; the played background music can be the background music corresponding to the first terminal, the played background music can also be a theme interface corresponding to the theme setting instruction by responding to the theme setting instruction triggered on the called interface, responding to the theme selection instruction on the theme interface, and acquiring the corresponding background music according to the theme setting instruction, wherein the acquired background music can be the same as the background music of the calling party or different from the background music of the calling party; the background music can be obtained from a local memory or a cloud memory, and the like.

In one embodiment, before sending the background music and the call voice to the called party corresponding to the call request, the method further comprises:

detecting the signal intensity corresponding to the session connection based on the session connection established by the call request; and when the signal intensity is smaller than the preset intensity, sending the call voice to a called party corresponding to the call request.

Wherein, the signal strength is used to indicate the strength of the current session connection establishment signal. The signal strength affects the audio quality of the call, and the audio quality of the call is poor when the signal strength is less than the signal strength required by the normal call. Signal strength can be expressed in power in dBm.

The preset intensity is a preset signal intensity, and when the signal intensity is greater than or equal to the preset intensity, the first terminal sends the background music and the call sound to a called party corresponding to the call request.

Specifically, before sending the background music and the call voice to the called party corresponding to the call request, the first Terminal sends an AT instruction to a corresponding Terminal Adapter (Terminal Adapter, TA) through an API interface, acquires the signal strength of the current session connection through a GET () function in the AT instruction, processes the call voice and the background music by using a digital signal processing algorithm if the acquired signal strength is greater than or equal to a preset strength, and sends the processed digital signal to the called party corresponding to the call request. And if the acquired signal intensity is smaller than the preset intensity, triggering the first terminal to generate a background music sending termination instruction, and sending the call voice to a called party corresponding to the call request. When the detected signal intensity is less than the preset intensity, the sending of the background music is stopped, and the effect that the audio quality is reduced because the sending of the background music occupies network bandwidth resources is avoided.

In one embodiment, the method further comprises:

detecting the first loudness of background music in real time;

and when the first loudness is greater than or less than the preset loudness, adjusting the first loudness of the background music to the preset loudness.

Wherein loudness is used to represent the size of the sound; the preset loudness is the preset loudness of background music; the first loudness is used to represent the size of the sound of the background music. It will be understood that the terms "first", "second", etc. as used herein may be used herein to describe different loudness, but that the loudness is not limited by these terms. These terms are only used to distinguish a first loudness from another loudness.

Specifically, a first terminal sends a call request, responds to a theme setting instruction triggered on a call interface corresponding to the call request, switches to a theme interface corresponding to the theme setting instruction, responds to a theme selection instruction triggered on the theme interface, acquires background music corresponding to the theme selection instruction, acquires call voice of a calling party, executes a corresponding background music loudness detection instruction when the first terminal sends the background music and the call voice to a called party corresponding to the call request, detects the first loudness of the background music in real time, compares the acquired first loudness with a preset loudness through a function, generates a loudness adjustment instruction when the first loudness is greater than or less than the preset loudness, executes the loudness adjustment instruction until the first loudness of the background music is adjusted to the preset loudness, avoids the loudness of the background music from influencing the sound effect of the call voice due to too large loudness or too small loudness by detecting the loudness of the background music in real time, detecting the loudness of background music in real time improves the audio quality effect of the call.

In one embodiment, the method further comprises:

detecting the first loudness of background music and the second loudness of call voice in real time;

and when the ratio of the first loudness to the second loudness is not equal to the preset ratio, adjusting the first loudness and the second loudness to the ratio equal to the preset ratio.

The preset ratio is a relative ratio of a first loudness and a second loudness, the preset ratio is a fixed value, there is an inverse proportion relationship between the first loudness and the second loudness, for example, k represents that the preset ratio is a constant, a represents the first loudness, b represents the second loudness, and the relationship between the first loudness and the second loudness can be expressed as a/b-k.

Specifically, the first terminal sends a call request, responds to a theme setting instruction triggered on a call interface corresponding to the call request, switches to a theme interface corresponding to the theme setting instruction, responds to a theme selection instruction triggered on the theme interface, acquires background music corresponding to the theme selection instruction, acquires call voice of a calling party, executes a background music loudness detection instruction and a call voice loudness detection instruction when the background music and the call voice of the calling party are sent to a called party corresponding to the call request, detects a first loudness of the background music and a second loudness of the call voice in real time, generates a first loudness adjustment instruction if the ratio of the first loudness to the second loudness is not equal to a preset ratio, executes the first loudness adjustment instruction according to the second loudness and the preset ratio until the first loudness of the background music is adjusted to be consistent with the ratio of the second loudness to be equal to the preset ratio, and sending the background music and the call voice of the calling party to a called party corresponding to the call request, receiving the call voice of the called party sent by the called party, and playing the background music and the call voice of the called party. The first loudness of the background music and the second loudness of the call voice are detected in real time, the first loudness of the background music is adjusted according to the preset ratio, the influence on the sound effect of the call voice caused by overlarge or undersize of the loudness of the background music is avoided, and the loudness of the background music is detected in real time, so that the audio quality effect of the call is improved.

In one embodiment, the method further comprises synchronizing the background music corresponding to the called party or the background music of the calling party according to the theme synchronization policy when detecting that the background music corresponding to the called party is different from the background music of the calling party.

The theme synchronization strategy is that when the background music of the calling party is different from the background music of the called party, the background music of the called party is synchronized into the same background music as the background music of the calling party. The method for detecting the background music can judge whether the background music of the calling party and the background music of the called party are the same or not by collecting the frequency of the background music and comparing the frequency, can also detect whether the background music of the calling party and the background music of the called party are the same or not by extracting the voiceprint of the background music, the voiceprint of the background music is extracted to firstly divide the background music into blocks, the background music of each block is subjected to Fourier change to obtain the characteristic value of each block, each characteristic value is sequenced according to the sequence, namely the voiceprint of the background music is obtained, and when the background music of the calling party and the background music of the called party are detected to be the same or not, only the judgment on whether the characteristic values of the background music of the calling party and. The theme synchronization policy may also be that when the background music of the calling party and the background music of the called party are different, the background music of the calling party is synchronized to the same background music as the background music of the called party.
