Fig. 3 is a flow chart illustrating a noise suppression method according to an exemplary embodiment, which includes the following steps, as shown in fig. 3.
310. In the communication process, the terminal acquires the noise level of the current communication signal.
During voice communication, noise is inevitably carried in the communication signal. Noise refers to unwanted interference signals other than useful signals in communication signals, wherein the noise may be from ambient background noise during voice communication, or from line noise, etc., and when the noise level in the communication signals exceeds a certain threshold, the quality of voice communication is affected.
The present invention provides a method for noise suppression according to user's setting, in the noise suppression method of the present invention, a terminal needs to acquire the noise level of the current communication signal, to determine whether noise suppression is currently required, i.e., whether the noise suppression interface of step 320 is currently provided, to this end, the terminal may only transmit a signal when the noise level of the current communication signal exceeds a preset threshold, and acquiring the noise level, in this case, the terminal only needs to acquire the noise level of the current communication signal, it may be determined that it is currently necessary to provide the noise suppression interface in step 320, and of course, the terminal may periodically acquire the noise level of the current communication signal, and detects whether the acquired noise level exceeds a preset threshold, and if so, the terminal provides the noise suppression interface in step 320.
Further, the present invention provides the following two ways how the terminal acquires the noise level of the current communication signal.
In the first mode, the terminal receives the noise level of the current communication signal transmitted by the other device except the terminal itself in the current communication link.
As described above, the communication link of the voice communication may include a plurality of devices, such as a base station controller, a core gateway, and the like, which may detect the noise level of the current communication signal, in some embodiments of the present invention, in one case, the devices may detect whether the noise level of the current communication signal exceeds a preset threshold, and if the noise level of the current communication signal exceeds the preset threshold, the devices may transmit the noise level of the current communication signal to the terminal periodically, and in another case, the terminals may detect whether the received noise level exceeds the preset threshold, which is not limited in the present invention.
In the second way, the terminal detects and acquires the noise level of the communication signal received by the terminal itself.
In voice communication, the terminal also has the capability of detecting the noise level in the communication signal, in this case, the terminal can automatically detect whether the noise level of the communication signal received by the terminal exceeds a preset threshold, and if the noise level exceeds the preset threshold, the terminal acquires the noise level of the current communication signal.
Still further, the present invention mentioned in the above description that the terminal and other devices in the current communication link can detect the noise level of the current communication signal, and there are many specific detection manners, which are not limited in this respect, for example, the noise level can be detected by tracking the noise energy, specifically, the noise energy is much smaller than the energy of the communication signal, so that the smaller signal energy, i.e., the noise energy, in the communication signal can be tracked by some algorithm, such as the minimum statistics control recursive average algorithm, and the noise level in the communication signal can be determined according to the noise energy.
In an embodiment of the present invention, after acquiring the noise level of the current communication signal, the terminal may further prompt the user to make the user know the noise level of the current communication signal, and in an embodiment of the present invention, the terminal may prompt the user only when the noise level of the current communication signal exceeds a preset threshold, and of course, the terminal may also prompt the user according to an operation of the user.
In the first mode, the terminal prompts the user of the noise level of the current communication signal in a voice playing mode.
Since the user is currently performing voice communication, the user can be prompted timely and effectively in a voice playing manner, and the content of the prompt may be "the current noise level is a" or "the current noise level is a, and it is recommended to perform noise suppression" or the like, which is not limited in the present invention.
In the second mode, the terminal prompts the noise level of the current communication signal to the user in a mode of displaying characters or graphs on an interface.
In an embodiment of the present invention, in order to ensure that the user is prompted in time about the noise level, the terminal may prompt the user in a manner of displaying text or graphics only when the current voice communication manner is hands-free, and the present invention is not particularly limited with respect to the display manner and the display content of the text or graphics.
320. The terminal provides a noise suppression selection interface for providing at least a suppression initiation option and at least one noise suppression intensity.
In step 310, when the terminal determines that noise suppression is currently required, a noise suppression selection interface may be provided, or the present invention may not perform step 310, in which case the terminal may provide the noise suppression selection interface according to the operation of the user, for example, the terminal may provide a noise suppression option on the communication interface, when the user feels that the current communication quality is poor, the noise suppression option may be triggered, and when the terminal detects the trigger operation, the noise suppression selection interface is provided.
The noise suppression selection interface may provide a suppression start option and at least one noise suppression strength, in an embodiment of the present invention, the suppression start option is used to turn on or off the noise suppression function, that is, when the current noise suppression function is in an on state, the noise suppression function is turned off after a trigger operation on the suppression start option is detected, and when the current noise suppression function is in an off state, the noise suppression function is turned on after a trigger operation on the suppression start option is detected, in another embodiment of the present invention, the suppression start option may be used only to turn on the noise suppression function, and the at least one noise suppression strength may be a noise suppression level, such as high, medium, low, or 90%, 80%, 50%, etc., or may be a noise suppression parameter, etc., which is not specifically limited in this respect, for example, a user of a terminal at a listening party may select the triggering suppression start option, so as to start the noise suppression function, and at the same time, the user of the terminal at the listening party can select the noise suppression strength to be "high" to perform the suppression of the maximum strength on the noise in the received communication signal, i.e. the sound signal sent by the opposite communication terminal.
330. And when the terminal detects the triggering operation of the inhibition starting option and the selection operation of any noise inhibition strength, receiving a noise inhibition instruction, wherein the noise inhibition instruction carries the noise inhibition strength.
The user can start the noise suppression function by triggering the suppression starting option, and in addition, the user can set the degree of noise suppression by selecting the noise suppression strength, when the terminal detects the triggering operation of the suppression starting option and the selection operation of any one noise suppression strength, a noise suppression instruction is generated according to the selection of the noise suppression strength by the user, so that the terminal receives the noise suppression instruction, as exemplified above, the noise suppression strength selected by the user of the terminal of the listener is "high", and the terminal of the listener can receive the noise suppression instruction according to the selection of the user, and the noise suppression instruction carries the noise suppression strength "high".
It should be noted that, if the noise suppression strength is a noise suppression level, the terminal may query the local database after receiving the noise suppression command to obtain a noise suppression parameter corresponding to the noise suppression level, and make the noise suppression request carry the noise suppression parameter when sending the noise suppression request in the subsequent step.
340. And the terminal acquires the communication network element identification in the current communication link.
In voice communication, after the communication connection is established, the communication network element in the current communication link is determined, these communication network elements may have a noise suppression function, so-called communication network elements, i.e. devices in the current communication link, such as base station controllers, core gateways, etc., for the purpose of noise suppression according to user settings, a noise suppression request carrying the above-mentioned noise suppression strength may be sent to the communication network elements, so that the communication network element receiving the noise suppression request may perform noise suppression according to the above-mentioned noise suppression strength, however, before sending the noise suppression request to the communication network elements, in order to specify which communication network elements should be sent the noise suppression request, the terminal needs to first obtain the identifiers of the communication network elements, that is, execute step 340, where the identifiers of the communication network elements are used to uniquely determine a certain communication network element.
Specifically, after the communication connection is established, the communication network element in the current communication link may send its own identifier simultaneously when forwarding the current communication signal according to the communication protocol, for example, when the base station controller forwards the current communication signal to the next-stage network element, it sends its own identifier simultaneously to it, and when the next-stage network element forwards the current communication signal to the next-stage network element, it not only forwards the identifier of the base station controller to it simultaneously, but also sends its own identifier to it, and so on, until the terminal receives the current communication signal, obviously, the terminal may also obtain the communication network element identifier in the current communication link simultaneously when receiving the current communication signal, of course, the method for the terminal to obtain the communication network element identifier in the current communication link may be more than this, for example, the communication network element may directly send its own identifier to the terminal without forwarding other communication network elements, etc., the present invention is not particularly limited.
The present invention also does not specifically limit the timing when the terminal acquires the communication network element identifier in the current communication link, and in practical applications, the terminal may acquire the communication network element identifier at any time after the communication connection is established, may also acquire the communication network element identifier after the terminal acquires the noise level of the current communication signal, and may also acquire the communication network element identifier after the terminal receives the noise suppression instruction.
It should be noted that, in some embodiments of the present invention, because some communication network elements do not have a noise suppression function, the terminal may not send a noise suppression request to these communication network elements, so that the terminal may only obtain a communication network element identifier having a noise suppression function in a current communication link, that is, in a specific implementation process, only the communication network element having a noise suppression function sends its identifier to the terminal, or the terminal may query, after obtaining the communication network element identifier, a specified server for the communication network element having a noise suppression function in the obtained communication network element identifier, and then the terminal obtains these communication network elements having a noise suppression function. Of course, the terminal may send a noise suppression request to all communication network elements in the communication link, and the communication network elements having the noise suppression function respond to the request, so as to perform noise suppression.
Of course, in other embodiments of the present invention, the terminal may also obtain all the identifiers of the communication network elements in the current communication link, or, on the premise of ensuring the noise suppression effect, in order to simplify the process and save the communication network expense, the terminal may also obtain only a part of the identifiers of the communication network elements in the current communication link, for example, the terminal may only obtain the identifiers of the communication network elements in the cell where the terminal is located, which is not specifically limited in this invention.
It should be further noted that, if the communication network element in the current communication link changes, for example, a situation that the communication network element changes occurs when the terminal moves across cells, at this time, the terminal may re-execute the process of acquiring the communication network element identifier in the current communication link.
350. And the terminal sends a noise suppression request carrying the noise suppression strength to at least one device of the communication network element, the terminal and the opposite communication terminal according to the communication network element identifier, so that the device receiving the noise suppression request performs noise suppression on the communication signal according to the noise suppression strength.
After acquiring the communication network element identifier, the terminal may send a noise suppression request to the communication network element in the current communication link according to the communication network element identifier, and on the premise that the terminal has a noise suppression function, the terminal may also send a noise suppression request to the terminal itself or the opposite communication terminal.
It should be noted that, if the terminal only sends the noise suppression request to itself or the correspondent node, but does not send the noise suppression request to the communication network element, the terminal may not execute the technical process of step 340.
Specifically, if the noise suppression strength carried in the noise suppression request is a noise suppression level, the device that receives the noise suppression request may query a corresponding noise suppression parameter according to the noise suppression level, and assign the noise suppression parameter to an interface parameter of a corresponding noise suppression module, so that the device that receives the noise suppression request performs noise suppression according to the queried noise suppression parameter, and if the noise suppression strength carried in the noise suppression request is a noise suppression parameter, the device that receives the noise suppression request may assign the noise suppression parameter to an interface parameter of the noise suppression module, so as to perform noise suppression according to the queried noise suppression parameter.
As for the specific method for the device receiving the noise suppression request to perform noise suppression, the present invention is not particularly limited, and in practical applications, the noise signal and the non-noise signal may be distinguished according to signal characteristics such as signal short-time stationarity, signal energy distribution characteristics, signal autocorrelation, and the like, and then the noise signal is suppressed according to the noise suppression strength.
In summary, in the noise suppression method provided in this embodiment, in the communication process, the terminal user is triggered to send a noise suppression request carrying noise suppression strength to at least one device of the communication network element, the terminal itself, and the communication peer in the current communication link according to the noise suppression requirement of the terminal user, and the noise suppression strength is set by the user, so that the device receiving the noise suppression request performs noise suppression according to the noise suppression strength, and thus the noise suppression method is more flexible, and because whether noise suppression is to be performed and the noise suppression strength are set by the terminal user according to the current communication quality, the phenomena of signal distortion and voice damage caused by noise suppression can be avoided.
