detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

FIG. 2 shows a WIFI access method according to an embodiment of the present invention. Referring to FIG. 2, the method includes:

S201: When the terminal recognizes that its LTE frequency band and the WIFI frequency band constitute interference, Take the signal quality of the LTE band in which it is located;

The parameters for evaluating the signal quality include a Signal to Interference plus Noise Ratio (SINR), and an SINR fluctuation value, that is, an absolute difference between the SINR value measured in the current period and the SINR value measured in the previous period. value. It should be noted that the parameters for evaluating the signal quality include many, and the embodiment of the present invention does not specifically limit this.

It should be noted that depending on the adopted standard, the LTE frequency band that interferes with the WIFI band will also be different. Certainly, the embodiment of the present invention does not impose specific restrictions on the LTE frequency band that interferes with the WIFI frequency band.

For example, when the terminal recognizes that the LTE frequency band and the WIFI frequency band are in interference, the terminal obtains the signal quality of the LTE frequency band, which includes: when the terminal recognizes that the frequency interval between the LTE frequency band and the WIFI frequency band is smaller than the preset At the frequency interval, the terminal acquires the signal quality of its own LTE frequency band.

The frequency interval between the LTE frequency band and the WIFI frequency band is the frequency interval between the highest frequency of the LTE frequency band and the lowest frequency of the WIFI frequency band, or the frequency interval between the lowest frequency of the LTE frequency band and the highest frequency of the WIFI frequency band.

It should be noted that the preset frequency interval is used to determine whether the LTE network signal and the WIFI network signal are likely to generate interference. When the frequency interval between the LTE frequency band and the WIFI frequency band is less than the preset frequency interval, the LTE network signal and the WIFI network are illustrated. The signal is easy to generate interference; when the frequency interval between the LTE frequency band and the WIFI frequency band is greater than the preset frequency interval, it indicates that the LTE network signal and the WIFI network signal are not easily interfered.

According to the current frequency distribution standard of the communication industry, the frequency range of the frequency band 40 of the TDD-LTE is 2300 MHz-2400 MHz, and the frequency range of the frequency band 7 of the FDD-LTE is 2500 MHz-2570 MHz, and the frequency range of the ISM frequency band used by the WIFI network is: 2.400MHz-2483.5MHz (see Figure 1). It can be seen that the frequency band 40 of TDD-LTE and the frequency interval between the frequency band 7 and the WIFI frequency band of FDD-LTE are very small, that is, the frequency interval is smaller than the preset frequency interval, so It is easy to cause mutual interference between LTE network signal and WIFI network signal.

Illustratively, FIG. 3 shows a method flow of another WIFI access method according to an embodiment of the present invention. Referring to FIG. 3, before the terminal recognizes that the LTE frequency band and the WIFI frequency band of the terminal constitute interference, the method further includes: S200 When the terminal recognizes that it has a cell reselection or a cell handover, it determines whether the LTE frequency band and the WIFI frequency band of the terminal constitute interference.

It should be noted that when the terminal performs cell reselection or cell handover, the LTE frequency band of the terminal also changes. Therefore, when the terminal recognizes that the cell reselection or cell handover occurs, the terminal actively determines whether the LTE frequency band and the WIFI frequency band are located. The interference is formed, and the signal interference between the LTE network and the WIFI network can be suppressed in time.

Preferably, when the terminal recognizes that the cell reselection or the cell handover occurs, determining whether the LTE frequency band and the WIFI frequency band of the terminal constitute interference, specifically: when the terminal recognizes that the cell reselection or cell handover occurs, and the LTE frequency band of the terminal occurs. When changing, the terminal determines whether its LTE frequency band and WIFI frequency band constitute interference.

S202: The terminal selects a frequency interval between the corresponding LTE frequency band and the WIFI frequency band according to the signal quality of the LTE frequency band in which the terminal is located;

The frequency interval between the LTE frequency band and the WIFI frequency band is the frequency interval between the central frequency point of the LTE frequency band and the central frequency point of the WIFI frequency band.

It should be added that the better the signal quality of the LTE band in which the terminal is located, the smaller the frequency interval between the LTE band and the WIFI band corresponding to the signal quality; conversely, the worse the signal quality of the LTE band in which the terminal is located, and the signal The frequency interval between the LTE band and the WIFI band corresponding to the quality is larger.

Illustratively, when the terminal recognizes that the LTE frequency band and the WIFI frequency band of the terminal are in interference, the signal quality of the LTE frequency band in which the terminal is located includes: when the terminal recognizes that the LTE frequency band and the WIFI frequency band of the terminal are in interference, the terminal periodically acquires itself. The signal quality of the LTE frequency band, and calculate the fluctuation value of the signal quality according to the periodically obtained signal quality; correspondingly, the end The terminal selects the frequency interval between the LTE frequency band and the WIFI frequency band according to the signal quality of the LTE frequency band, and specifically includes: when the signal quality fluctuation value is greater than the preset threshold, the terminal selects the signal quality according to the LTE frequency band of the current period. The frequency interval between the corresponding LTE band and WIFI band.

It should be noted that the fluctuation value of the signal quality is the absolute difference between the signal quality measured in the current period and the signal quality measured in the previous period.

S203: The terminal selects a corresponding WIFI channel number according to the frequency interval.

The WIFI channel number is a channel identifier used when the WIFI network performs channel division on the ISM frequency band. Figure 4 shows the correspondence between the WIFI channel number and the WIFI band. According to the IEEE802.11b standard, the 2.4-GHz-ISM band is divided into 14 WIFI channels, and the bandwidth of each WIFI channel is 22 MHz. Accordingly, the WIFI channel number is corresponding. It is 1-14. In practical applications, the division of the frequency bands may be different according to the communication standard, and the embodiment of the present invention does not specifically limit this.

FIG. 5 shows a first detailed embodiment of a WIFI access method according to an embodiment of the present invention. Referring to FIG. 5, the method includes:

S501: When the terminal recognizes that the cell reselection or the cell handover occurs, the terminal acquires the LTE frequency band in which the terminal is located;

S502: The terminal determines whether the LTE frequency band in its own location changes, and if yes, step S503 is performed;

S503: The terminal determines whether the LTE frequency band in which the LTE frequency band is located is the frequency band 40 of the TDD-LTE or the frequency band 7 of the FDD-LTE, and if yes, step S504 is performed;

S504: The terminal acquires a signal quality of the LTE frequency band in which the terminal is located.

S505: The terminal selects a frequency interval between the corresponding LTE frequency band and the WIFI frequency band according to the signal quality of the LTE frequency band in which the terminal is located;

Table 1 shows the correspondence between the signal quality SINR of the LTE frequency band preset by the terminal and the frequency interval between the LTE frequency band and the WIFI frequency band.

Table 1

信号质量(dB)Signal quality (dB)	频率间隔(MHz)Frequency interval (MHz)
SINR<＝10SINR<=10	4040
10<SINR<＝2010<SINR<=20	3030
20<SINR<＝3020<SINR<=30	2020
30<SINR30<SINR	1010

S506: The terminal selects a corresponding WIFI channel number according to the frequency interval.

Table 2 shows the correspondence between the frequency interval preset by the terminal and the WIFI channel number. For example, the terminal works in the frequency band 40 of the TDD-LTE, and the frequency interval between the LTE frequency band and the WIFI frequency band is 40 MHz. Since the highest frequency of the frequency band 40 is 2400 MHz, the frequency of the WIFI network should be at least greater than 2440 MHz, and the frequency is greater than 2440 MHz. The WIFI channel number is 11-14 (the frequency range of WIFI channel number 11 is 2451 MHz - 2473 MHz). That is, the terminal selects the corresponding WIFI channel number 11-14 according to the frequency interval of 40 MHz.

Table 2

频率间隔(MHz)Frequency interval (MHz)	WIFI信道号WIFI channel number
4040	11-1411-14
3030	8-148-14
2020	6-146-14
1010	4-144-14

In step S501 to step S506, the terminal ensures that there is a certain frequency interval between the LTE frequency band and the WIFI frequency band of the terminal by selecting an appropriate WIFI channel number, thereby effectively suppressing signal interference between the LTE network and the WIFI network.

S602: The terminal acquires an SINR value when a period set by the periodic timer arrives, and calculates a SINR fluctuation value according to the SINR value.

The SINR fluctuation value is an absolute difference between the SINR value measured in the current period and the SINR value measured in the previous period.

S603: The terminal determines whether the SINR fluctuation value is greater than a preset threshold, and if yes, executing step S604;
