the edge data center is a data center which is located close to the user side locally and can provide services for the local user, and the local user does not need to access a remote data center, so that the edge data center can provide high-bandwidth and low-delay access application for the user.
For example, the processing mode of the edge data center is applied to the internet of vehicles, the processing of the edge data center with low time delay can enable the internet of vehicles to reach a specified security level, wherein the server based on the edge data center can sink to each node of the network edge, and the network time delay is saved.
Specifically, the edge data center can be used as a server arranged at the edge of each community network, and various collected sample data are processed through the server arranged at the edge of the network.

Based on the specific characteristics of ultra-low time delay, ultra-high speed and massive connection of the 5G network, when a large amount of data needs to be calculated locally and a terminal is issued, the large amount of data can be processed in real time and efficiently by using an edge data center under the 5G network.
The edge data center in this embodiment is a 5G edge data center application layer, and the 5G edge data center application layer is formed by an application server and is responsible for processing analysis of data edge calculation, providing an application interface, and displaying data.

The specific implementation of the method is shown in fig. 1, and the implementation steps are as follows:
step 101: dividing the monitored environment area into grid areas corresponding to different environment attributes, and dividing each grid area into at least one fine grid;
step 102: processing the sampling data of the terminal in the fine grid area based on an edge data center, determining a terminal behavior parameter warning value corresponding to the fine grid, and determining a terminal behavior parameter in the fine grid area;
step 103: and determining whether the fine grid generates user group aggregation behavior according to the terminal behavior parameter warning value corresponding to the determined fine grid and the terminal behavior parameter in the fine grid area.
In implementation, the environment attribute is different environment attributes determined according to different purposes of different building areas, so that grid areas with different environment attributes are determined.
Specifically, in order to determine a grid area of the environment attribute, and thus determine a place where the user group gathering behavior occurs, the environment area needs to be divided into grid areas of different environment attributes according to the usage of the building environment area. Taking the west lan station as an example, the environment area of the west lan station can be divided into the following grid areas with different environment attributes according to different purposes:
the system comprises a south-north station house, an overhead waiting hall, a south-north city corridor, an overhead lane, a landing platform, a platform canopy and a logistics channel;
in implementation, the grid region is determined, that is, the occurrence positions of the aggregation behaviors of the user group in the grid region are determined, and in order to reduce the range of the determined occurrence positions of the aggregation behaviors of the user group as much as possible, each grid region can be divided into at least one fine grid;
as shown in fig. 2, a grid area covering the elevated layer ticket region is divided into 4 fine grids: covering the northwest of the elevated ticket checking area, covering the northeast of the elevated ticket checking area, covering the southwest of the elevated ticket checking area and covering the southeast of the elevated ticket checking area; divide a grid area of the canopy of the covering station layer into 4 fine grids: the platform layer rain shed comprises a west-north side covering the platform layer rain shed, a east-north side covering the platform layer rain shed, a west-south side covering the platform layer rain shed and an east-south side covering the platform layer rain shed.
In implementation, the edge-based data center may be a 5G edge data center, and the sampling data of the terminal in the fine grid area may be a terminal behavior parameter in the RRU and/or a terminal behavior parameter determined by SIM card identification information of the terminal.
As an optional implementation manner, the terminal behavior parameter in the fine grid region is any one or any multiple of the following parameters determined according to the sampling data of the terminal in the fine grid region, and the parameters include:
terminal number, traffic growth, and overflow rate probability.
In an implementation, the terminal behavior parameter alert value is also any one or any plurality of the following parameters determined according to the sampling data of the terminal in the fine grid area, and includes:
terminal number, traffic growth, and overflow rate probability.
Specifically, the terminal behavior parameter warning value is obtained by performing edge calculation on terminal sampling data in a pre-divided fine grid area based on an edge data center under the condition that no user group aggregation behavior occurs, that is, under the normal condition, the obtained terminal behavior parameter warning value is judged based on common sense, the movement of group users under the normal condition is ordered, the positions of the group users are distributed according to a certain rule, that is, the positions of terminals in the fine grid area are distributed according to a certain rule, and the interaction data of the terminals and the network equipment in the fine grid area have a certain rule, so that the terminal behavior parameter warning value of each fine grid area under the normal condition can be determined according to the terminal behavior parameter value in each fine grid area.
The terminal behavior parameter warning value in the fine grid area is lower than the terminal behavior parameter value under the normal condition in the fine grid area.
For example: the method includes the steps that a terminal behavior parameter value in a fine grid area is a telephone traffic increase amount, the subway station is a transfer station, after a train arrives at the subway station, a user finishes getting on or off the train in a short time, the user needing to go out of the train is gathered to a stairway to go out of the train along a side platform, the user needing to be transferred enters another platform along a transfer line, if the user going out of the train or the user needing to be transferred starts to talk or surf the internet at the moment, the telephone traffic in the fine grid area can be judged to rise sharply according to interactive data of the terminal and network equipment, the fact that under normal conditions, after the subway enters the train, the telephone traffic in the fine grid area appears a peak on the transfer line or the train going out is judged, if the subway enters the train for 5 times within one hour, the peak of the telephone traffic in the fine grid area can appear for 5 times, the interactive data of the terminal and the network equipment in the fine grid area can be stated to have a certain regularity, therefore, the terminal behavior parameter in the fine grid area can be calculated according to the average value of the normal conditions, and the warning behavior parameter can be determined.
The terminal behavior parameters in the fine grid region correspond to the terminal behavior parameter alert values, that is, when the terminal behavior parameters in the fine grid region are the number of terminals, the terminal behavior parameter alert values corresponding to the fine grid are the number of terminals in the fine grid region when no group aggregation behavior occurs in the fine grid region; when the terminal behavior parameters in the fine grid region are the traffic increase amount and the overflow rate probability, and the warning value of the terminal behavior parameters corresponding to the fine grid is the traffic increase amount and the overflow rate probability in the fine grid region when the group aggregation behavior does not occur in the fine grid region.
The number of terminals in the terminal behavior parameter values can indicate the number of users using the terminals in the fine grid region, the traffic increase amount can indicate whether the traffic of the users using the terminals in the fine grid region for voice call is increased compared with the normal traffic in the time period, so that whether group aggregation behavior occurs in the fine grid region can be determined, the overflow rate probability can indicate the total number of overflow times and the total number of test call times of the users using the terminals in the fine grid region on a signaling channel SDCCH, and whether the total number of overflow times and the total number of test call times in the time period are increased compared with the normal situation, so that whether the group aggregation behavior occurs to the users in the fine grid region is determined, and therefore, the group aggregation behavior occurs to the users in the fine grid region is determined according to whether the number of terminals in the fine grid region, the traffic increase amount and the overflow rate probability are higher than the normal standard.
As an optional implementation, determining the number of terminals according to the sampling data of the terminals in the fine grid region includes:
and determining the number of the terminals in each fine grid area according to the SIM card identification information of the user identification card in the sampling data of the terminals in each fine grid area.
In implementation, the number of the terminals is determined by sampling the SIM card identification information in the data.
Specifically, each intelligent terminal is provided with an SIM card for normal use of network data service, each SIM card number ICCID is unique, the number of the terminals can be counted by collecting the ICCID, and if the terminal is a mobile subscriber, the number of the mobile subscriber can be counted by collecting the IMSI.
In the concrete implementation, if all mobile, unicom and telecommunication users are counted, the workload is too large, therefore, only the number of the mobile users is counted according to the mobile user identification IMSI, and finally the number of all terminal users is calculated according to the proportion of the mobile, unicom and telecommunication users.
In implementation, the number of terminals in the fine grid area interacting with the RRU currently is determined according to the remote radio RRU device, as shown in fig. 3.
The RRU device mainly performs filtering, signal amplification, and up-down conversion processing on radio frequency signals, and uses a digital intermediate frequency technology to realize conversion from intermediate frequency analog signals to baseband digital signals. Determining the number of terminals in a fine grid area through terminal voice/data in the fine grid area which is detected by RRU equipment and interacts with RRU currently, wherein the specific method comprises the following steps:
the base station is configured to be S/2/3/3, and the carrier frequency number of each sector in the three sectors is 2, 3 and 3 respectively;
1 carrier frequency needs to be configured with 8 channels, 2 carrier frequencies need to be configured with 16 channels, and 1 of the 16 channels is selected as a Broadcast Control Channel (BCCH) transmission Control signal;
if the rest 15 channels are all used as Traffic channels TCH (Traffic Channel) to transmit voice/data Traffic;
if the remaining 15 channels satisfy the simultaneous call of 15 full-rate users or 30 half-rate users, the call loss is 2%;
determining the traffic volume corresponding to 15 channels to be 5.411Erl according to an Ireland B capacity table, determining the traffic volume of each user to be 0.025Erl according to a traffic model, and determining the capacity =5.411/0.025=216.44, namely determining the user number to be 216.44.
In fig. 3, the grid area is identified as seven lihe _ lang west station _ E607528, which is divided into 8 fine grid areas: the number of users in the grid area is equal to or greater than a predetermined number of users in the destination area, and the number of users in the grid area is equal to or greater than a predetermined number of users in the destination area, wherein the number of users in the grid area is equal to or greater than a predetermined number of users in the destination area, and the number of users in the grid area is equal to or greater than a predetermined number of users in the destination area.
As an optional implementation manner, determining the traffic increase amount and the overflow rate probability according to the sampling data of the terminal in the fine grid region includes:
and determining the traffic increase amount and the overflow rate probability in each fine grid area according to the voice data transmitted in the voice channel and the signaling data transmitted in the signaling channel in the sampling data of the terminal in each fine grid area.
In the implementation, the signaling data transmitted by the signaling channel comprises the total number of traffic overflow times and the total number of traffic call trial times in the independent dedicated control channel SDCCH;
the voice data transmitted in the voice channel comprises the total number of voice overflow and the total number of voice call trial.
Fine grid region overflow probability = fine grid region overflow rate exceeding a set threshold number/total traffic statistics report number of fine grid region 100%.
The fine grid region overflow rate is the fine grid region SDCCH telephone traffic overflow rate; or
Voice overflow rate of voice channel in fine grid area;
the traffic overflow rate of the SDCCH can be calculated by the following formula:
the SDCCH traffic overflow rate = SDCCH overflow total times in busy hour/SDCCH call test total times in busy hour;
the speech overflow rate can be calculated by the following formula:
voice channel voice overflow rate = total number of voice channel overflow times in busy hour/total number of voice channel call attempts in busy hour; wherein busy hour is defined as a period of 24 hours a day for counting the maximum value of voice data of the voice channel according to the period, and is a busy hour, for example, the busy hour can be defined as 10-11 a.m..
In practice, the determined traffic/uplink RLC throughput (bps) in the fine grid area changes when aggregation action occurs, for example: the fine grid area is a square, when aggregation occurs in the fine grid area, the traffic/uplink RLC throughput of the fine grid area is 6.3ERL/20Mbps, and under the normal condition that aggregation does not occur, the traffic/uplink RLC throughput of the fine grid area is 5.6ERL/8Mbps, so when aggregation occurs in the fine grid area, the traffic/uplink RLC throughput is greatly increased to be higher than the traffic/uplink RLC throughput of the fine grid area under the normal condition, and the voice/traffic overflow rate can exceed 20%.
The throughput rate is an average rate of successful delivery of data through a communication channel or a node in a unit time, and generally, in units of bits per second (bps), the higher the uplink RLC throughput rate, the higher the traffic volume, the more likely congestion occurs in a voice data transmission channel.
In implementation, the edge data center is used for processing the sampling data of the terminal in the fine grid area, and determining the terminal behavior parameter warning value corresponding to the fine grid under normal conditions, taking a western lanzhou passenger station as a grid area for example, and dividing the western lanzhou passenger station into 14 fine grid areas, as shown in fig. 2, the specific implementation steps are as follows:

wherein, the terminal behavior parameter is any one of the following parameters:
probability of overflow rate, traffic growth, number of terminals.
Specifically, the x-axis is operated, the terminal behavior parameters of the current unit fine grid on the x-axis are determined, and the integral value IM of the x-axis in the fine grid area where the current unit fine grid is located is obtained iA Determining the terminal behavior parameters in the current fine grid region according to the following formula:
