Description

Technical Field

[0001] The present invention relates to the technical field of virtual simulation of network communication equipment, and in particular to a device and method for simulating and generating base station performance index values. Background Art

[0002] With the development of 5G technology and the rise of demand for 5G private network construction, the demand for 5G deployment and operation engineers is growing. In the process of cultivating network deployment talents, it is necessary to use the network communication equipment virtual simulation training system to help users complete standard base station deployment and maintenance operations, including hardware installation and power-on, software debugging, business commissioning, etc.

[0003] Base station is a high-power multi-channel two-way radio transmitter station fixed in one place. They are typically used for two-way wireless communication in low-power channels, such as mobile phones, handheld phones and wireless routers. Radio frequency unit is a device responsible for the interface processing of baseband module and radio frequency module signals, as well as uplink and downlink baseband signal processing, such as common RRU, AUU, pRRU wireless devices, etc. Performance indicator is an indicator that can be used to analyze project performance and equipment operation quality issues in detail. It defines "what to measure", the quantity that must be collected to complete the network service quality measurement, such as the number of requests, voice call drop rate, user downlink average throughput, etc. A base station is connected to 1-6 radio frequency units, which send and receive wireless signals and generate base station performance indicator data. The performance indicator data generated by a real base station has the following four characteristics: 1) It can be generated in real time; 2) Different users query the same performance indicator of the same radio frequency unit at the same time and the same base station, and the indicator value generated is unique, identical, and unchanged; 3) The same performance indicator of the same radio frequency unit, or the same performance indicator of all radio frequency units under the same base station, shows a normal distribution over time in a day; 4) The same base station and the same performance indicator show random discreteness within a certain proportion range in the same period of time every day (the shortest is within 15 minutes). Since obtaining the real base station performance indicator value poses a data privacy security risk, even operators cannot legally disclose base station performance indicator data.

[0004] In the teaching or experimental scenario of 5G base station performance index analysis, the simulation scheme for base station performance index is usually "real base station performance index value * floating value". This scheme can generate data close to the real base station performance index, but it cannot generate index values ​​of multiple base stations, multiple radio frequencies, multiple indicators, and multiple time periods. For example, to simulate and generate index values ​​of 60 base stations, 3 radio frequency units, once every 15 minutes, 50 indicators, and 30 days, using this scheme, 51,840,000 copies of data need to be generated. Saving it in a regular computer or applying it to virtual simulation software will occupy a large amount of computer storage resources and slow down the computer operation speed. Therefore, based on this scheme, about 10,000 copies of data are usually used for repeated use, which greatly reduces the diversity of data and cannot ideally simulate the real base station performance index value, affecting the index analysis effect. Summary of the invention

[0005] The purpose of the present invention is to provide a device and method for simulating and generating base station performance indicator values ​​that can be widely used in teaching scenarios of mobile communication technology network optimization, help users greatly reduce the time cost and opportunity cost of obtaining performance indicator value data, can generate a unique indicator value according to a specified time, a specified base station, a specified base station performance indicator, and a specified radio frequency unit, and the simulated performance indicator data has four characteristics of real performance indicator data, and can meet the user's needs for big data analysis of performance indicator values.

[0039] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.

[0040] Example 1

[0041] This embodiment presents the generation process of the indicator value of "the maximum number of users in the RRC connected state in the cell" in 6 radio frequency units of 60 base stations for 3 consecutive days with a period of 15 minutes:

[0042] Step S1): The system pre-installs a base converter in the text conversion component to convert hexadecimal text into decimal numbers.

[0043] Step S2): As shown in "Table 3 Maximum number of users in RRC connected state in the cell", the system presets the base station performance indicator name "Indicator value in RRC connected state in the cell", as well as the corresponding standard value "100" and floating range value "10%" in the performance indicator component.

[0044] Step S3): As shown in Table 4, user online rates in different time periods, the system presets the time period and the corresponding user online rate in the time period component.

[0045] Step S4): The user enters in the UI component, time = 0:0:00 on January 1, 2022 to 23:45:00 on January 3, 2022, base station name = 101-160, RF unit name = 101-106, base station performance indicator name = the maximum number of users in the RRC connected state in the cell, time period = every 15 minutes, the UI component sends the time, base station name, and RF unit name to the text conversion component, sends the base station performance indicator name to the performance indicator component, and sends the time period to the time period component.

[0046] Step S5): The text conversion component converts time = January 1, 2022 to 20220101, converts time = January 3, 2022 to the numerical format 20220103, converts time = 0 hours, 0 minutes, 0 seconds to the numerical format 0, converts time = 23 hours, 45 minutes, 00 seconds to the numerical format 234500, converts base station = 101~160 to the numerical format 101~160 for a total of 60 numerical values, converts the radio frequency unit name = 101~106 to the numerical format 101~106 for a total of 6 numerical values, and sends the numerical values ​​to the calculation component.

[0047] Step S6): The performance indicator component sends the standard value "100" and the floating range value "10%" corresponding to the base station performance indicator name "maximum number of users in RRC connected state in the cell" to the calculation component.

[0048] Step S7): The time period component sends all user online rates corresponding to the time period "every 15 minutes" to the calculation component, for example, at 00:00:00, the user online rate = 27.22%.

[0049] Step S8): The calculation component sums the time conversion value, the base station name conversion value, and the RF unit name conversion value, and assigns it to K. For example, the calculation component calculates 20220101÷(0+101×101)=1982.16851289 through the formula "K=year-month-day value÷(hour-minute-second value+base station value×RF unit value)", and rounds to two decimal places, K=1982.17.

[0050] Step S9): The calculation component intercepts the last two digits of K and assigns them to ks, ks=17;

[0051] Step S10): The calculation component reads and determines that the first bit value 1 of K is an odd number, and multiplies the value of ks by 1, and the calculation result is equal to 17.

[0052] Step S11): The calculation component calculates through the formula "indicator value = standard value * user online rate * (1 + floating range value * ±ks%)", for example, standard value = 100, user online rate = 27.22%, floating range = 10%, ± take +, ks = 17, indicator value = 100*27.22%*(1+10%*17%) = 27.68274, the rounded indicator value = 27, and the value is assigned to P = rounded indicator value = 27.

[0053] Step S12): The calculation component sends the P value to the UI component.

[0054] Step S13): The UI component presents the calculation result value.

[0055] According to the above rules, a total of 103,680 performance indicator value data are generated. Figure 3 As shown in the figure, through data analysis, the indicator values ​​show a normal distribution over time.

[0060] Example 2

[0061] Based on the indicator value generation process of Example 1, the calculation process of the maximum number of users in the RRC connected state in the cell of 160 base stations and 106 radio frequency units at 23:45:00 on January 3, 2022 is as follows: 1) K = year, month, day value ÷ (hour, minute, second value + base station value × radio frequency unit value) = 20220103 ÷ (234500 + 160 × 106) = 80.4108129, rounded to two decimal places, K = 80.41, the last two digits of K are intercepted and represented by ks, and the first digit of K is intercepted. If it is an even number, ks is a negative number, ks = -41; 2) Indicator value = standard value * user online rate * (1 + floating range value * ks%) = 100 * 33.19% * [1 + 10% * (-41%)] = 31.82921, the rounded indicator value = 31.
