Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a method for switching a squelch level according to an exemplary embodiment, where the method for switching the squelch level is used in a terminal, as shown in fig. 1, and includes the following steps 101 and 103:

in step 101, a current received signal strength parameter value of a current talk channel is detected.

In step 102, a target squelch level corresponding to the received signal strength parameter value range in which the current received signal strength parameter value is located is determined according to a correspondence between a preset received signal strength parameter value range and a squelch level.

In step 103, the current squelch level is switched to the target squelch level.

Here, the receiving sensitivity of the intercom is limited, and according to different protocols, the sensitivity can be in the range of-100 dBm to-125 dBm, the higher the sensitivity is, the farther the relative communication distance is, but the more serious the corresponding interference is, namely, the noise of the call is larger. Therefore, in different communication environments, it is important to reasonably adjust the squelch level to obtain good call quality.

The muting function of the intercom is to strictly filter out excessive background noise, eliminate or suppress the background noise when no signal is received, and keep the speaker silent when no signal is received by the intercom. The purpose of muting is to strictly suppress noise, but if suppression is excessive, weak call signals are also limited and not received. Especially when talking over long distances, weak telecommunication signals are suppressed along with noise, which is not preferable. The purpose of adjusting the squelch level is to suppress or eliminate unwanted noise to different degrees according to different communication environments, so that the noise is not transmitted through the speaker, but the call signal (even in the case of weak noise) is transmitted.

In this embodiment, it may be set that: the higher the squelch level is, the stronger the squelch suppression capability is, and the less easily a useful weak signal to be received is received; conversely, the lower the squelch level grade is, the weaker the squelch suppression capability is, the easier it is to receive a weak useful signal; of course, the higher the squelch level, the weaker the squelch suppression capability may be set, and is not limited herein. The following examples are described by taking as an example that the higher the squelch level, the higher the squelch suppression capability.

Here, the principle of switching the muting levels is determined according to the communication environment where the intercom is located, and when the intercom is in a longer communication distance, the signal strength of the received signal will be weakened, and the required muting level will be smaller, so that the intercom can easily receive a weak useful signal. When the communication distance of the user is short and the signal strength of the received signal is strong, the required squelch level is higher, so that the noise can be greatly suppressed, but a useful strong signal can still be received. In the embodiment, the test can be performed in the development stage of the interphone, the call quality under each squelch level is tested when the signals received by the interphone are different received signal strength parameter values, and the squelch level corresponding to the best call quality when the different received signal strength parameter values are determined; therefore, according to the test result, namely the corresponding squelch grade when the call quality is best when different received signal strength parameter values exist, the corresponding relation between the received signal strength parameter value range and the squelch grade is determined, so that the call quality obtained by using the corresponding squelch grade is best under the condition that the signal strength received by the interphone is in the corresponding received signal strength parameter value range. After the corresponding relationship between the received signal strength parameter value range and the squelch level is tested, the research and development personnel can store the corresponding relationship between the received signal strength parameter value range and the squelch level into the interphone. The received signal strength parameter value herein refers to some parameter value that can identify the received signal strength.

It should be noted that, for different intercom products, the correspondence between the received signal strength parameter value range and the squelch level will be different, and research personnel can respectively test and obtain the correspondence between the received signal strength parameter value range and the squelch level for different intercom products.

Here, when the intercom is in use, the current received signal strength parameter value of the current communication channel of the intercom can be detected, and then the target muting level corresponding to the received signal strength parameter value range in which the current received signal strength parameter value is located can be determined according to the corresponding relation between the preset received signal strength parameter value range and the muting level, wherein the target muting level is the muting level with the best intercom communication quality under the condition of the current received signal strength parameter value. Therefore, the interphone can switch the current squelch level to the target squelch level.

Of course, it is possible that the current squelch level is the target squelch level, and the intercom may then maintain the current squelch level. When the current squelch level is different from the target squelch level, the interphone can switch the current squelch level to the target squelch level.

According to the embodiment, the mute level of the interphone is automatically switched by detecting the current received signal strength parameter value of the current call channel without the setting of a user, the mute level is accurately determined, the current mute level can be adjusted in real time according to the current received signal strength parameter value, the adjustment is timely, and the call quality of the interphone is improved.

In one possible implementation, the Received signal strength parameter value includes RSSI (Received signal strength Indication).

For example, the correspondence between the preset RSSI value range and the squelch level may be as shown in table 1.

RSSI value range	Squelch rating
		-125～-122dBm	1
-121～-118dBm	2
		-117～-114dBm	3
-113～-110dBm	4
		-109～-107dBm	5
-106～-103dBm	6
		…	…

TABLE 1

For example, assuming that the current muting level is level 5, when it is detected that the current received signal strength parameter value of the current talk channel of the intercom is-115 dBm, referring to table 1, the corresponding target muting level is level 3, and at this time, the current muting level may be switched from level 5 to level 3.

In a possible implementation, step 101 in the above-mentioned muting level switching method can be implemented as step a 1.

In step a1, when an RSSI circuit is integrated in the interphone chip, the current RSSI value is read from the register of the interphone chip.

Here, an RSSI circuit is integrated in a chip of some interphone, the RSSI circuit is used for detecting a current received signal strength parameter value, and the RSSI circuit feeds back the current received signal strength parameter value to an MCU (Micro control unit) for adjusting a front stage gain.

Here, after receiving the current RSSI value detected by the RSSI circuit, the MCU may store the current RSSI value in the register of the MCU, so that the interphone can directly read the current RSSI value from the register of the interphone chip, thereby obtaining the current RSSI value conveniently and quickly.

In a possible implementation, the step 101 in the squelch level switching method described above can be implemented as steps B1 and B2.

In step B1, when the RSSI circuit is not integrated in the intercom chip, the RSSI detection circuit is connected to the receiving circuit of the intercom, and the RSSI detection circuit is used to obtain the instantaneous value of the RSSI.

In step B2, the instantaneous values of the RSSI are averaged to obtain the current RSSI value.

Here, there is no RSSI circuit integrated in the chip of some walkie-talkies, and at this time, the RSSI detection circuit may be accessed in the receiving circuit of the walkie-talkie, and fig. 2 is a schematic diagram illustrating the RSSI detection circuit being accessed in the receiving circuit of the walkie-talkie according to an exemplary embodiment. As shown in fig. 2, the receiving circuit of the intercom includes a mixer circuit 21, an intermediate frequency amplifier 22 and an intermediate frequency filter 23 connected in series, after receiving the received signal, the intercom may perform frequency mixing processing on the received signal and the local oscillator signal sent by the transmitter 24 through the mixer circuit 21, part of noise signals in the received signal after frequency mixing may enter an intermediate frequency, then the signal to be measured generated after intermediate frequency amplification through the intermediate frequency amplifier 22 and intermediate frequency filtering through the intermediate frequency filter 23 is a useful signal from which part of noise signals are filtered, and the signal to be measured is input to the RSSI detection circuit, so that the instantaneous value of the RSSI of the useful signal may be detected. The RSSI detection circuit comprises a comparator 24 and an RSSI detection chip 25; one input end of the comparator 24 inputs a signal to be detected output by the intermediate frequency filter, and the other input end inputs a reference voltage; the input end of the RSSI detection chip 25 is input into the comparator24, and the output end of the RSSI detection chip outputs the instantaneous value of the RSSI. Here, the RSSI detection circuit may perform baseband IQ power integration within time t us to obtain an instantaneous value of RSSI, and for example, when t is 104, the instantaneous value of RSSI may be represented by the following formula:

here, after acquiring the instantaneous value of the RSSI output from the RSSI detection chip 25, the intercom may average the instantaneous values of the multiple RSSIs to obtain the current RSSI value. For example, at t 104, the instantaneous values of 8192 RSSIs may be averaged to obtain an average value of 1s of RSSI,

in one possible embodiment, the step B1 in the squelch level switching method described above can be implemented as steps B11 and B12.

In step B11, the instantaneous value of RSSI output by the RSSI detection circuit is converted into a digital signal by an analog-to-digital (AD) converter.

In step B12, the current RSSI value is obtained by averaging instantaneous values of RSSI in the form of a plurality of digital signals.

Here, the instantaneous value of the RSSI output by the RSSI detection chip is an Analog signal, and for convenience of calculation and storage, the intercom may convert the instantaneous value of the RSSI output by the RSSI detection circuit into a Digital signal through an Analog-to-Digital (AD) converter, and then average the instantaneous values of the RSSI in the form of a plurality of Digital signals to obtain the current received signal strength parameter value, so that the calculation is convenient.

The implementation is described in detail below by way of several embodiments.
