Background

With the development of electronic terminals and network technologies, the popularity of electronic terminals such as mobile phones, tablet computers, smart watches, etc. supporting various different types of networks is increasing. However, when signal transmitters of different types of networks simultaneously operate in some frequency bands with similar frequencies, mutual interference exists between the signal transmitters, and thus the communication quality is reduced.

To solve the above problems, the current common technologies mainly include the following two technologies:

1. the out-of-band rejection capability of a filter when signal transmitters of different types of networks work in a mutual interference working frequency band is increased on hardware, and the isolation of antennas of the signal transmitters of the different types of networks is increased;

2. the interference party is reduced in power when operating so as to reduce interference to the other party.

However, increasing the out-of-band rejection of the filter means that a better filter needs to be used, thus greatly increasing the cost of the hardware. The method of reducing the power of the interfering party may cause frequent disconnection during communication due to the reduction of the power, thereby affecting the communication quality.

Detailed Description

In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Please refer to fig. 1, which is a flowchart illustrating an implementation of a communication method according to an embodiment of the present application. The method can be applied to electronic devices, such as: mobile electronic devices such as mobile phones, tablet computers and laptop computers which can process data in a mobile manner, or non-mobile electronic devices such as liquid crystal televisions, all-in-one machines and desktop computers which can not process data in a mobile manner. The electronic device is configured with a plurality of antennas and radio frequency modules for supporting a plurality of different types of networks. As shown in fig. 1, the method mainly includes:

101. when mutual interference exists between first network communication and second network communication, a first signal-to-noise ratio and a second signal-to-noise ratio of an interfered party when the interfering party stops signal transmission and signal transmission are obtained;

102. analyzing the difference value of the first signal-to-noise ratio and the second signal-to-noise ratio to obtain the current signal state of the interfered party;

103. if the signal state is a weak signal state, controlling the interference party to start a time division multiplexing mode;

104. and if the signal state is a strong signal state, controlling the interference party not to start the time division multiplexing mode.

The first network communication is of a different type than the second network communication. In a practical application, the first network communication may be a cellular mobile network communication, in particular an LTE (Long Term Evolution) communication. The second network communication may be a WIFI (wireless fidelity network) communication. Wherein, LTE can work in the frequency channel similar to 2.4G WIFI frequency, if: b7, B40, B41, and the like.

Specifically, whether mutual interference exists between the first network communication and the second network communication can be determined according to working frequency bands (or frequency points) of the first network communication and the second network communication. Wherein the mutual interference may comprise: the first network communication and the second network communication interfere with each other, the first network communication unilaterally interferes with the second network communication, or the second network communication unilaterally interferes with the first network communication.

It can be appreciated that when the first network communication and the second network communication interfere with each other, the signal status analysis needs to be performed on both the first network communication and the second network communication. When the first network communication unilaterally interferes with the second network communication, only the signal state of the second network communication as an interfered party is analyzed. When the second network communication unilaterally interferes with the first network communication, only the signal state of the first network communication as an interfered party is analyzed.

When mutual interference exists between the first network communication and the second network communication, a first Signal-To-Noise Ratio (SNR) and a second SNR of the interfered party when the interfering party stops Signal transmission (TX off) and Signal transmission (TX on) are obtained. And comparing the difference value of the first signal-to-noise ratio and the second signal-to-noise ratio with the normal demodulation threshold value of the interfered party, and analyzing to obtain the current signal state of the interfered party. If the signal state is a weak signal state, controlling the interferer to start TDM (Time division multiplexing); and if the current signal state of the interfered party is a strong signal state, controlling the interfering party not to start the TDM.

Taking LTE and WIFI as examples, the principle of controlling to enable TDM described above is that a method of determining whether time division needs to be enabled according to SNR of both communication parties, that is, when interference of one party does not interfere reception of the other party, the method does not need to enable TDM mechanism. Assuming that 10dB (decibel) interference is actually measured on CH2 of WIFI under the maximum output power of a 2370Mhz (megahertz) frequency point of LTE B40, when the signal-to-noise ratio of a signal received by a receiver of WIFI is greater than a normal demodulation threshold at this time, even if LTE has interference on WIFI, the demodulation of the receiver of WIFI is not affected because the ratio of signal noise of WIFI is large enough, and at this time, a TDM mechanism is not used. In contrast, when TX (Transmit, signal transmission power) of WIFI has interference to LTE, but when SNR of LTE is sufficiently large, WIFI does not enable TDM mechanism.

According to the communication method provided by the embodiment of the application, when mutual interference exists between first network communication and second network communication, a first signal-to-noise ratio and a second signal-to-noise ratio of an interfered party when the interfering party stops signal transmission and signal transmission are obtained, then the current signal state of the interfered party is analyzed according to the obtained first signal-to-noise ratio and the obtained second signal-to-noise ratio, and whether the time division multiplexing mode is required to be started by the interfering party is intelligently judged according to the analysis result. The interference party can be controlled to start the time division multiplexing mode when needed according to the current signal state of the interfered party in a non-hardware mode, so that the cost can be saved, the problem of signal mutual interference can be effectively solved, the communication quality is ensured, and the problems that the throughput of a network is reduced and the communication resources are wasted due to the fact that a time division mechanism is started in a strong signal state can be avoided.

Please refer to fig. 2, which is a flowchart illustrating an implementation of a communication method according to an embodiment of the present application. The method can be applied to electronic devices, such as: mobile electronic devices such as mobile phones, tablet computers and laptop computers which can process data in a mobile manner, or non-mobile electronic devices such as liquid crystal televisions, all-in-one machines and desktop computers which can not process data in a mobile manner. The electronic device is configured with a plurality of antennas and radio frequency modules for supporting a plurality of different types of networks. As shown in fig. 2, the method mainly includes:

201. through testing, interference noise in all channels of first network communication and second network communication which are interfered with each other when an interference party enables signal transmission in different channels is obtained respectively;

202. generating an interference noise table according to each interference noise obtained by testing;

and the interference noise table is used for storing the corresponding relation between the frequency points corresponding to the channels with mutual interference and the interference noise obtained by testing in all the channels of the first network communication and the second network communication. It will be appreciated that interference does not exist between all channels.

The first network communication is of a different type than the second network communication. In a practical application, the first network communication may be a cellular mobile network communication, in particular an LTE communication. The second network communication may be a WIFI communication. Wherein, LTE can work in the frequency channel similar to 2.4G WIFI frequency, if: b7, B40, B41, and the like.

Specifically, taking LTE and WIFI as examples, through testing, noise that LTE falls within the WIFI band and noise that WIFI falls within the LTE band are obtained respectively.

Taking a mobile phone as an example, suppose that a frequency point (or a frequency band) of LTE operation is x, a frequency point of WIFI operation is y, and x and y are 1 to N. The channels correspond to the frequency points one by one.

The method for acquiring the noise falling into the WIFI band in the LTE comprises the following steps: the method comprises the steps of controlling WIFI to receive and close signal transmission (LTE CHx TX on, WIFIHy Rx Path Open (TX off)) in different channel enabling signals while controlling LTE to transmit the enabling signals in different channels, testing the noise size received by the WIFI of the mobile phone, recording the noise size as LTE to WIFI noise [ x ] [ y ], and recording measured data in the mobile phone.

The method for acquiring the noise of the WIFI falling in the LTE band comprises the following steps: the method comprises the steps of controlling WIFI to enable signal transmission on different channels, controlling LTE to enable signal reception on different channels and turn off signal transmission (WIFI CHx TX on, LTECHy Rx Path Open (TX off)), testing the noise size received by the LTE of the mobile phone, recording the noise size as WIFI to LTE noise [ x ] [ y ], and recording measured data in the mobile phone.

Optionally, the noise is in-band noise (in-band noise).

And testing noise (noise) of all channels with mutual interference of LTE and WIFI through the above acquisition mode, generating a corresponding interference noise table, and storing the interference noise table into a memory of the mobile phone. The form of the interference noise table may be one table corresponding to one network type, or one table corresponding to multiple network types. In one practical application, the interference noise table may be as shown in the following table.

TABLE 1LTE To WIFI interference Noise Table (LTE To WIFI Noise Table)

The first row in table 2 shows different frequency points of WIFI, the first column shows different frequency points of LTE, and the in-band noise received by LTE at different frequency points when signals are transmitted at different frequency points by WIFI is recorded in the crossed grid of the two. Such as: NOISE [1] [1] is in-band NOISE received by LTE at frequency point CH1 when WIFI generates signals at frequency point CH 1.

It should be understood that the above frequency points CH1 and CH2 … … CH … are only examples, and in practical applications, the specific operating frequency range is determined by practical requirements, and the application is not limited in particular.

203. Determining whether mutual interference exists between the first network communication and the second network communication according to an interference noise table;

the mutual interference may include: the first network communication and the second network communication interfere with each other, the first network communication unilaterally interferes with the second network communication, or the second network communication unilaterally interferes with the first network communication.

Specifically, the interference noise table (as shown in table 1 and table 2) is queried whether frequency points corresponding to a first channel of the first network communication connection and a second channel of the second network communication connection exist. And if the frequency points corresponding to the first channel and the second channel exist in the plurality of interference noise tables, confirming that mutual interference exists between the first network communication and the second network communication, and executing the subsequent steps of acquiring a first signal-to-noise ratio and a second signal-to-noise ratio of the interfered party when the interfering party stops signal transmission and signal transmission respectively based on the first network communication and the second network communication.

And if the frequency points corresponding to the first channel and the second channel do not exist in the interference noise tables, confirming that mutual interference does not exist between the first network communication and the second network communication, and not executing subsequent steps.

And if the frequency points corresponding to any one of the first channel and the second channel exist in the plurality of interference noise tables, confirming that mutual interference exists between the first network communication and the second network communication, and executing the subsequent steps of acquiring a first signal-to-noise ratio and a second signal-to-noise ratio of the interfered party when the interfering party stops signal transmission and signal transmission respectively based on the party with the corresponding frequency points.

204. When mutual interference exists between first network communication and second network communication, acquiring the strength of an effective signal received by a first channel connected with an interfered party and real-time noise in the first channel received by a receiver of the interfered party when the interfering party stops signal transmission on a second channel connected with the interfering party, and acquiring interference noise in the first channel when a second channel enabling signal is transmitted according to an interference noise table;

205. taking the ratio of the intensity of the effective signal to the real-time noise as a first signal-to-noise ratio, and taking the ratio of the intensity of the effective signal to the sum of the real-time noise and the reference interference noise as a second signal-to-noise ratio;

206. comparing the difference between the first signal-to-noise ratio and the second signal-to-noise ratio with a demodulation threshold of a receiver of the interfered party;

207. if the difference is larger than the demodulation threshold value, the interfered party is confirmed to be in a strong signal state, and if the difference is smaller than the demodulation threshold value, the interfered party is confirmed to be in a weak signal state;

taking LTE and WIFI of which the first network communication and the second network communication are mobile phones respectively as an example, the LTE and the WIFI interfere with each other, and then real-time noise of LTE (in actual use) and real-time noise of WIFI are acquired in real time respectively.

Specifically, on one hand, WIFI is used as an interferer, LTE is used as an interfered party, and assuming that LTE works on a channel x and WIFI works on a channel y, when the mobile phone is in use, the strength of an effective signal (or a useful signal) received by the mobile phone on an LTE CHx channel is read and recorded as LTE-S [ x ], and when WIFI stops signal transmission on a CHy channel (WIFI CHy TX OFF), the noise level received by an LTE receiver is read and recorded as LTE-noise [ x ].

On the other hand, LTE is used as an interfering party, WIFI is used as an interfered party, and if the WIFI works on a channel x and the LTE works on a channel y, the strength of an effective signal received by a WIFI CHx channel of the mobile phone is read and recorded as WIFI-Sx when the mobile phone is in use, and the noise received by a WIFI receiver is read and recorded as WIFI-noise [ x ] when the LTE stops signal transmission (LTE CHy Tx OFF) on the CHy channel.

For interference of LTE to WIFI, first, using formula 1: WIFI-Sx/WIFI-Nosie [ x ], and obtaining a first signal-to-noise ratio; using equation 2: and obtaining a second signal-to-noise ratio by the WIFI-Sx/(WIFI-Nosie x + LTE to WIFI Nosie x ] [ y ]), wherein the LTE to WIFI Nosie x ] [ y ] is interference noise in the first channel x connected with the WIFI of the interfered party when the second channel y connected with the LTE serving as the interfering party transmits signals, and the interference noise can be obtained by specifically inquiring the table 1. Then, a difference C between the first signal-to-noise ratio and the second signal-to-noise ratio is calculated. And then, comparing the difference value C with a demodulation threshold value of the WIFI receiver, if the difference value C is larger than the demodulation threshold value, confirming that the WIFI is in a strong signal state, and if the difference value C is smaller than the demodulation threshold value, confirming that the WIFI is in a weak signal state.

Further, in another embodiment of the present invention, in order to avoid frequent switching of the TDM mechanism when the effective signal is at a critical point of the strong and weak signals, different demodulation threshold values are determined according to a strength change of the effective signal received by the interfered party. Taking the interference of LTE to WIFI as an example, the intensity change of an effective signal received by a WIFI CHx channel of a mobile phone is obtained, if the intensity of the effective signal is weakened or unchanged, the first threshold is used as a demodulation threshold, and if the intensity of the effective signal is strengthened, the second threshold is used as a demodulation threshold, and the second threshold is greater than the first threshold.

In particular, according to WIFI-Sx]Judging whether the current connection is carried out according to the sizes of the front and the back moments_{Harvesting machine}Whether the effective signal strength is getting larger or smaller.

When the effective signal strength WIFI-Sx is weakened or unchanged, if the difference value C is larger than a first demodulation threshold value NF _ WIFI, the WIFI is considered to be in a strong signal receiver and can be demodulated normally, the WIFI is in a strong signal state, and the LTE does not need to start a TDM mechanism. The demodulation threshold NF of the WIFI receiver is a short name of NoiseFigure, and is a fixed constant greater than 0. If the difference value C is smaller than NF-WIFI, the WIFI is considered to be in a weak signal state at the moment, the risk that the WIFI receiver cannot demodulate the WIFI is possibly existed, the WIFI is in a weak signal, and the LTE needs to start a TDM mechanism.

When the effective signal strength WIFI-Sx is in a strengthened state, if the difference value C is larger than a second demodulation threshold value NF _ WIFI + N (N is a fixed constant larger than 0), the receiver can demodulate the WIFI in a strong signal state at the moment, the WIFI is in a strong signal state, and the LTE does not need to start a TDM mechanism. If C is smaller than NF-WIFI + N, the WIFI is considered to be in a weak signal state at the moment, the WIFI receiver may have the risk of being incapable of demodulating, the WIFI is in a weak signal, and the LTE needs to start a TDM mechanism.

It can be understood that, for the interference of WIFI to LTE, the analysis method is similar to the interference of LTE to WIFI, except that the C value is selected with reference to the demodulation coefficient NF-LTE of the LTE receiver. The difference value N between the second demodulation threshold and the first demodulation threshold is selected to ensure that the judgment standards of the strong and weak signals are inconsistent when the strength of the effective signal received by the interfered party is enhanced and weakened, so as to avoid frequent switching of the TDM mechanism when the effective signal is at the critical point of the strong and weak signals.

208. And if the signal state of the interfered party is a weak signal state, controlling the interfering party to start the time division multiplexing mode, and if the signal state of the interfered party is a strong signal state, controlling the interfering party not to start the time division multiplexing mode.

Specifically, the strong and weak signals of the two interfering parties can be analyzed according to the above steps, and the principle of activating the TDM mechanism is shown in table three below.

Table 3TDM mechanism execution conditions

WIFI Signal Strength	LTE signal strength	TDM mechanism
			High strength	High strength	WIFI and LTE do not enable TDM
High strength	Weak (weak)	WIFI enables time division, LTE does not enable TDM
			Weak (weak)	High strength	WIFI (Wireless Fidelity) time division-free and LTE (Long term evolution) TDM-enabled
Weak (weak)	Weak (weak)	Both WIFI and LTE are TDM enabled

It can be understood that in a scenario where only one party interferes with the other party, whether TDM is enabled by the interfering party is selectively controlled according to the signal state of the interfered party. Specifically, if the interfered party is in a strong signal state, the interfering party does not enable TDM, and if the interfered party is in a weak signal state, the interfering party enables TDM.

For further understanding of the communication method provided by the present application, for example, it is assumed that the noise level of LTE CH39150 falling to WIFI CH4 is-125 dBm/Hz, the noise level of WIFI CH4 falling to LTE CH39150 is-130 dBm/Hz, and LTE and WIFI interfere with each other.

In the real-time nosie acquisition stage, if the size of an effective signal received by the LTE CH39150 is-117 dBm/Hz, the strength of the effective signal received by the WIFI CH4 is-120 dBm/Hz, the size of real-time noise received by the LTE CH39150 is-140 dBm/Hz, the real-time noise received by the WIFI CH4 is-140 dBm/Hz, and for the interference of the LTE to the WIFI, the NF _ WIFI value is assumed to be 6dB, and the N value is 2 dB.

According to the steps, firstly, WIFI-S [4]/WIFI-Nosie [4] (after being converted into logarithm, the calculation method is that minus 120dBm minus 140dBm) is equal to 20dB, and WIFI-S [4]/(WIFI-Nosie [4] + LTE to WIFINOSI [4] [39150]) is calculated to be equal to 5 dB. The difference C is 20dB-5 dB-15 dB.

If the effective signal strength received by the WIFI is increasing, since C (15dB) is greater than NF _ WIFI + N (8dB ═ 6dB +2dB), the WIFI is considered to be in a strong signal state, and the LTE does not need to enable the TDM mechanism. If the signal strength received by the WIFI is reduced or unchanged, C (15dB) is greater than NF _ WIFI (6dB), the WIFI is considered to be in a strong signal state, and the LTE does not need to start a TDM mechanism.

It can be understood that, for the case where C is less than NF _ WIFI or NF _ WIFI + N, it may be determined whether to enable the TDM mechanism by looking up table three.

It can be understood that, for the case where WIFI interferes with LTE, corresponding operations may be performed according to the processing logic for the case where LTE interferes with WIFI, which is not described herein again.

According to the communication method provided by the embodiment of the application, when mutual interference exists between first network communication and second network communication, a first signal-to-noise ratio and a second signal-to-noise ratio of an interfered party when the interfering party stops signal transmission and signal transmission are obtained, then the current signal state of the interfered party is analyzed according to the obtained first signal-to-noise ratio and the obtained second signal-to-noise ratio, and whether the time division multiplexing mode is required to be started by the interfering party is intelligently judged according to the analysis result. The interference party can be controlled to start the time division multiplexing mode when needed according to the current signal state of the interfered party in a non-hardware mode, so that the cost can be saved, the problem of signal mutual interference can be effectively solved, the communication quality is ensured, and the problems that the throughput of a network is reduced and the communication resources are wasted due to the fact that a time division mechanism is started in a strong signal state can be avoided. Particularly, in the Volte call scene when the LTE works in a frequency band (B7/B40/B41) close to the frequency of 2.4 GWIFISI, the network communication quality can be greatly optimized, so that WIFI games or internet surfing can be smoother, and the user experience is improved.
