Example III
Fig. 3 is a flow chart of an NTN connection selection method based on resident data according to a third embodiment of the present application. The scheme makes better improvement on the first embodiment, and the specific improvement is as follows: determining a target satellite based on the signal power information and the residence time duration jointly, comprising: acquiring the signal power information and the weighting coefficient of the residence time length; normalizing the signal power information and the residence time length; and determining the target satellite according to the normalized signal power information, the residence time length and the corresponding weighting coefficient.

S305, carrying out normalization processing on the signal power information and the residence time length;
The normalization process may be a process of mapping data to a uniform range or normalization to eliminate dimensional differences or data distribution differences between different data. Normalization may allow for comparability of different features or indicators, facilitating data analysis, model training, and algorithm application. Common normalization processing methods include min-max normalization, Z-Score normalization, decimal scale normalization, and normalization to unit length.
Specifically, the min-max normalization maps data linearly to a range between a specified minimum and maximum; Z-Score normalization converts the data into a standard normal distribution with a mean value of 0 and a standard deviation of 1 for normalization; decimal scaling normalization divides the data by an appropriate radix such that the absolute value of the data falls within the range of [ -1, 1) or [0, 1); normalization to unit length converts data vectors into unit length, commonly used for text classification and vector similarity calculation.
The Z-Score normalization does not have any manually set parameters or ranges, and compared with other normalization processes, the processed results are more objective and accurate, so that the Z-Score normalization can be adopted in the normalization process.
The general steps of Z-Score normalization include: calculating a mean value (mean) and a standard deviation (standard_displacement) of all samples, wherein the mean value represents the mean value of the data, and the standard deviation represents the discrete degree of the data; for each data point, the Z-Score value was calculated using the following formula:
Where x is the raw data point, mean is the mean and standard_displacement is the standard deviation.
