as shown in fig. 1, the method for intelligently saving energy of a multiband wireless network device in this embodiment includes at least a first network and a second network, where the device power consumption of the first network is higher than that of the second network, and taking a 5G network and a 2G network as examples below, the method includes the following steps:
s101: acquiring time period data information of the 5G wireless network equipment in an idle state within 24 hours;
the method comprises the steps of collecting time period data information of 5G wireless network equipment BBU/RRU in a 24-hour state in a working state, recording the time period data information of the 5G wireless network equipment BBU/RRU in a 24-hour idle state, and collecting and counting the idle state time period according to time periods within 2 hours, 2-3 hours, 3-4 hours, 4-5 hours and more than 5 hours.

S102: and taking the time section data information as the input of a statistical model, and performing statistics to obtain the sleep state period of the 5G wireless network equipment.
Specifically, collected time period data information of the 5G wireless network equipment in an idle state is used as input of a statistical model, and a sleep state cycle of BBU/RRU of the 5G wireless network equipment is obtained through statistics; the acquired time period data information in the idle state is used as the input of the analysis statistical model, so that the analysis data is more accurate and more flexible, and the sleep time can be dynamically adjusted according to the working state of the wireless network equipment.
Wherein the statistical model is established according to a mathematical statistical principle. In the sampling process, when the sampling frequency is more than or equal to 50 times, the mathematical statistics shows that: when the sub-sample with the sampling n being more than or equal to 50 is a big sub-sample. The estimation of the standby period of the 5G wireless network equipment can adopt a method of estimating a population mean interval by using big subsamples in mathematical statistics, and the statistical model is as follows: the distribution of the sampling analysis interval X is arbitrary and, as can be seen from the central limit theorem, a subsample (X) is used 1 ，X 2 ，…，X n ) Independent co-distribution, there is a limited mathematical expectation that the average standby period and variance of 5G wireless network devices will be: e (X) n )＝μ，D(X n )＝σ 2 . Available subsample (X) 1 ，X 2 ，…，X n ) The interval estimation is performed on the maternal average, i.e. the average standby period of the 5G wireless network devices.
From the central limit theorem, when n is large, X follows approximately a normal distribution. And also
Therefore, it is not only easy to use
Obeying a standard normal distribution.
When n is large, σ ≈ S (subsample standard deviation), and substitution with S has little effect on its distribution, so when n is large:
in the formula: u-an estimation function;
mu-maternal mean, i.e. 5G wireless network device average sleep period;
sigma-standard deviation of samples
n-sampling frequency.
(1) The equation still follows a standard normal distribution. Using the U test, a probability of 1-alpha (0) is given<α<1) 1-alpha is usually 90%, 95%, 99%, and a standard normal distribution can be found with respect to
Upper quantile of
The following steps are performed:
namely:
the confidence interval for μ is then:
wherein:
in the formula:
-sampling a sample mean;
u-sampling statistic;
s-sample standard deviation;
n-frequency, i.e. sampling frequency.
The determination of the sleep state period of the 5G wireless network device is divided into the following two cases according to the number of sampling analysis:
(1) when the sampling number, namely the sampling frequency n is more than or equal to 50, the sample is a big subsample, and the average value of the samples approximately follows normal distribution. According to the estimation method of the average number interval of the big subsamples to the matrixes in mathematical statistics, a confidence interval of the average sleep period mu of the 5G wireless network equipment can be obtained, and for insurance, the lower limit of the confidence interval is taken as the sleep period of the equipment.
(2) When the number of samples n <50, X is considered to be a discrete distribution, whose arithmetic mean is taken as its device standby period, i.e.:
in the formula:
-sampling a sample mean;
n-frequency, i.e. sampling frequency.

And the standby state time of the 5G wireless network equipment is adjusted at any time so as to ensure that the 5G wireless network equipment is in a standby energy-saving mode in a no-service state. By collecting the time period data information in the idle state as the input of the analysis statistical model, the analysis data is more accurate and has more flexibility, and the dormancy time can be dynamically adjusted according to the working state of the wireless network equipment, so that the wireless network equipment is in an energy-saving and power-saving mode to the maximum extent under the condition of ensuring normal working.

s1032: and if the time period is in the idle state, controlling the 5G wireless network equipment BBU/RRU to enter an equipment sleep state.
S104: and searching whether the emergency command signal transmitted by the base station antenna exists when the second network is accessed to the emergency telephone in real time.
Specifically, when a 5G network is in a dormant state, 2G network equipment with lower power consumption under the same coverage with the 5G network is still in a working state, when someone dials an emergency call through the 2G network, a base station antenna can transmit an emergency instruction signal, and the emergency instruction signal transmitted by the base station antenna is searched in real time; the emergency telephone comprises a conventional emergency telephone with a default system, such as 110/119. Also included are manually entered designated phones and arbitrary phones. Through flexible setting, the method can be widely applied to different demand scenes, and the application scenes are supported to be wider.
S105: after the emergency instruction signal is searched, the first network wireless network equipment is awakened to enter the working state from the dormant state through electromagnetic waves.
The method comprises the following steps: and after the emergency command signal transmitted by the base station antenna is searched, awakening the 5G network wireless network equipment from the dormant state to the working state through electromagnetic waves. The smoothness of the wireless network in an emergency state is ensured, and the applicability of the network in an emergency situation is achieved.
