At present, a cell-based user perception rate capacity expansion method is based on the service type proportion under a cell and the corresponding service theoretical demand rate for capacity expansion, but in the method, the user perception rate is not accurately calculated, the data transmission rate of the cell cannot be accurately represented, and the network capacity expansion precision is poor.
In order to solve the problem of the prior art, embodiments of the present invention provide a network capacity expansion method and apparatus, an electronic device, and a computer storage medium. First, a network capacity expansion method provided in an embodiment of the present invention is described below. Fig. 1 is a schematic flow chart of a network capacity expansion method according to an embodiment of the present invention, as shown in fig. 1, the network capacity expansion method includes:
s101, acquiring the total data throughput and the number of data transmission users of a cell in a preset time period.
The preset time period includes the queuing delay time of the data packet in the data throughput process in the time period, and the time period may be half an hour, 1 hour, 2 hours, and the like, and is not particularly limited. In order to obtain more accurate total data throughput and number of data transmission users, in an embodiment, obtaining total data throughput and number of data transmission users of a cell in a preset time period may generally include: acquiring the total throughput of time-level data and the number of time-level data transmission users corresponding to a plurality of preset time periods in a cell; determining the maximum total throughput of time-level data as the total throughput of data; and determining the number of the time-level data transmission users corresponding to the maximum total throughput of the time-level data as the number of the data transmission users.
In order to determine a more accurate capacity expansion amount of the carrier, in an embodiment, after acquiring the total data throughput and the number of data transmission users of the cell in a preset time period, the method may further include: and determining the service type of the cell based on the total data throughput and a preset total data throughput threshold. According to the service types, the cells can be divided into a large packet cell, a medium packet cell and a small packet cell, and the capacity expansion quantity of carriers required by the cells with different service types is different.
S102, determining the user perception rate by utilizing the preset time interval, the total data throughput and the number of data transmission users.
Because the preset time interval contains the queuing delay time of the data packet in the data throughput process in the time interval, the user perception rate determined by the preset time interval, the total data throughput and the number of data transmission users can more accurately represent the data transmission rate of the cell compared with the prior art. In one embodiment, the user perceived rate may be determined by the formula "total data throughput/(number of data transmission users × preset time period)".
S103, determining the carrier expansion quantity of the cell based on the total data throughput, the number of data transmission users and the user perception rate.
Since the user perception rate determined in S102 is more accurate, the carrier capacity expansion amount determined based on the total data throughput, the number of data transmission users, and the user perception rate is also more accurate, that is, the network capacity expansion accuracy is improved.

The first mapping relation information can be represented by a first curve, and the first curve represents the mapping relation between the total data throughput and the number of data transmission users; the second mapping information may be represented by a second curve representing a mapping between the user perceived rate and the number of data transmission users.
To determine a more accurate carrier expansion amount, in an embodiment, determining the carrier expansion amount of the cell based on the total data throughput, the user sensing rate threshold, and the service bearer traffic threshold may generally include: determining the total required number of carriers of a cell by utilizing a packet knapsack algorithm based on the total data throughput, the user perception rate threshold and the service bearing flow threshold; and determining the carrier capacity expansion quantity of the cell by utilizing the total carrier required quantity and the current carrier quantity of the cell. Wherein, the packet knapsack algorithm is defined as: with N items and a backpack with a volume V, the space cost for the ith item is ci and the value is wi. The items are divided into K groups, with the items in each group conflicting with one another, with at most one selected, and the solution of which items to pack in the backpack maximizes value. In one embodiment, a packet knapsack algorithm may be used to determine the amount of carrier expansion needed for cells of different traffic types.

and determining the total required number of carriers by using a packet knapsack algorithm based on the cell uplink data throughput and the cell downlink data throughput, the cell uplink user sensing rate and the cell downlink user sensing rate, the cell uplink user sensing rate threshold and the cell downlink user sensing rate threshold, and the cell uplink service carrying flow threshold and the cell downlink service carrying flow threshold.
The network capacity expansion method provided by the embodiment of the invention is characterized in that the total data throughput and the number of data transmission users of a cell in a preset time period are obtained, the preset time period comprises the queuing delay time of a data packet in the data throughput process in the time period, so that the user perception rate determined by the preset time period, the total data throughput and the number of the data transmission users can be used for representing the data transmission rate of the cell more accurately compared with the prior art. The capacity expansion quantity of the carriers is determined based on the user sensing rate, and the capacity expansion precision of the network can be improved.
The above description is described with reference to a specific embodiment, and with reference to fig. 2, the specific embodiment includes:
1. and extracting the busy hour index of the cell.
And acquiring 15-minute granularity original counter data by using a northbound interface to establish a cell hour granularity wireless index library, and calculating a cell day-level self-busy hour index. The self-busy hour refers to one hour with the maximum data throughput in one day of a cell; the cell day-level self-busy hour indexes mainly comprise: a cell effective Radio Resource Control (RRC) connection average user number, a cell uplink and Downlink flow, a cell uplink Physical Resource Block (PRB) utilization rate, a cell Downlink PRB utilization rate, a cell Physical Downlink Control Channel (PDCCH) Control Channel Element (CCE) utilization rate, a user sensing rate without a first packet queuing delay, and a user sensing rate with a first packet queuing delay.
2. The improved definition and capacity expansion thought of the user perception rate.
(1) Limitations of traditional user perceived rate:
the 3rd Generation Partnership Project (3 GPP) definition of user-perceived rates does not include The first packet queuing delay, which is a significant impact on user perception. For example, the perception of public transport during peak hours of the day, directly calculating the length of time a passenger takes from boarding to disembarking can be a significant departure from the user's actual experience if the length of time the passenger is waiting in line for boarding is not considered.
(2) And (3) calculating the user perception rate including the queuing delay of the first data packet:
the conventional user experience rate without the first packet queuing delay (total throughput of data sent by the packet data convergence protocol layer-packet data convergence protocol throughput of the last transmission time interval with the buffer empty)/deduct the data transmission time length after the last transmission time interval with the buffer empty. Among them, Packet Data Convergence Protocol (PDCP), Transmission Time Interval (TTI).
If a cell has only one user, the user perceived rate including the first data packet queuing delay is the user data transmission amount/the time when the user has data transmission (including the first data packet queuing delay).
If a cell has N users simultaneously transmitting data, the average user sensing rate of all users in the cell is (user 1 data transmission amount/user 1 data transmission time + user 2 data transmission amount/user 2 data transmission time + … …)/the number of data transmission users is (user 1 data transmission amount + user 2 data transmission amount + … …)/(user data transmission time + number of data transmission users) is the total cell data transmission amount/(user data transmission time + number of data transmission users).
The following indicators can be derived from the session statistics: speech system time (T), total cell data transmission amount (B) of a cell in the speech system time, and the number (N) of data transmission users in a period; however, the average number of users (assumed to be Nx) when the cell has data buffered or the air interface has scheduling and the time (assumed to be Ty) when the cell has data buffered or the air interface has scheduling cannot be obtained. According to the definition of the session index for the average data transmission user, it can be derived: n × T ═ Nx × Ty, thereby obtaining: the user perception rate is B/(Nx Ty) ═ B/(N × T).
(3) Definition of improved user perception rate:
defining the total data throughput volume (average number of users in cell: 3600 second) sent by PDCP layer of the cell when the improved user perception rate is the busy time
Through the data verification of the current network, the user perception rate without the queuing delay of the first data packet and the user perception rate with the queuing delay of the first data packet have the following variation trends in the same busy time: along with the increase of the number of users, the user perception rate containing the queuing delay of the first data packet is gradually reduced and is lower than the user perception rate without the queuing delay of the first data packet, and finally, the user perception rate and the user perception rate are both close to 0. Therefore, the user perception rate containing the queuing delay of the first data packet can more accurately represent the data transmission efficiency.
(4) Capacity expansion thought based on improved user perception rate:
in a Long Term Evolution (LTE) network, a shared channel provides users with shared resources, and the more users, the less resources are available to a single user, and the lower the relative rate is. When the user rate is reduced, the longer the transmission time of the same flow is; when the user rate is lower than a certain value, the large-packet users such as videos can leave the network without enduring the buffering time and the blocking; as the user rate continues to drop, packets of web pages or the like are successively removed from the network due to the long experience of the open time. The capacity expansion based on an improved user perception rate should therefore be evaluated from the following points:
a) the redefined improved user perception rate index must contain the first data packet queuing delay to truly reflect the user perception situation.
b) And finding out the lowest sensing speed value for inhibiting the increase of the user flow from the dimensionalities of the data transmission quantity, the user quantity and the sensing speed of the cell.
c) And judging and calculating the required carrier number according to the service volume according to the sensing rate required by each service of the large, medium and small packets.
3. Improved user perceived rate and traffic knee calculation.
The improved user perception rate calculation formula yields: the user perception rate is proportional to the data transmission quantity and inversely proportional to the user quantity. When the flow required by the user is constant, the flow of the cell smoothly increases along with the increase of the number of the users; similarly, when the cell traffic amplification is lower than the user number amplification, the user delay is increased, the average user traffic in the same time is reduced, the user demand is inhibited, and the user perception experience is deteriorated. Therefore, the minimum demand point of the corresponding user perception rate can be obtained by finding out the flow amplification inflection point according to the judgment. The evaluation principle can be specifically shown in fig. 3, where the intersection point of the curve of the experience rate and the cell traffic in fig. 3 is the minimum demand point of the traffic amplification inflection point and the user perception rate. Based on fig. 3, it is able to extract the speech system data of the current network cell, and judge the uplink and downlink sensing rates and the flow inflection points of the large, medium and small packet service cells according to the above principle, so as to obtain the user sensing rate and the service volume bearing threshold which can satisfy the user's good experience in each service scene, as shown in table 1, the threshold in table 1 is derived according to the TDD 20MHz bandwidth cell index, and the adjustment can be performed in the later period according to the network change and the service development condition.

4. And calculating the carrier capacity expansion requirement by using a packet knapsack algorithm.
(1) The packet knapsack algorithm defines:
there are N items and a backpack with a capacity V. The space cost of the ith item is ci and the value is wi. The items are divided into K groups, with the items in each group conflicting with one another, with at most one selected, and the solution of which items to pack in the backpack maximizes value. The algorithm can be used for solving the capacity expansion demand carrier number of each type of cell in the large, medium and small packets.
(2) The carrier requirement calculating process by using a grouping knapsack algorithm:
and f [ i ] [ j ] represents the backpack calculation demand carrier with the capacity j of each group of articles i of the large and medium small bags, if the uplink or downlink sensing speed of the cell is smaller than the backpack capacity (sensing baseline), calculation is carried out, and if the uplink or downlink sensing speed of the cell is larger than the backpack capacity, discarding is carried out. The formula is as follows:
f [ i ] [ j ] ═ max ([ x1/a1], [ x2/a2], [ b1/y1], [ b2/y2]) (i belongs to group k) (1)
Wherein, a 1: the uplink data transmission quantity/MHz factor is equal to the uplink data transmission quantity baseline/the bandwidth of a modeling cell, a big packet a1 is 0.05GB/MHz, a middle packet a1 is 0.035GB/MHz, and a small packet a1 is 0.025 GB/MHz; a 2: downlink data transmission quantity/MHz factor is equal to downlink data transmission quantity baseline/modeling cell bandwidth, a big packet a2 is 0.4GB/MHz, a middle packet a2 is 0.3GB/MHz, and a small packet a2 is 0.15 GB/MHz; x 1: cell uplink data transmission quantity/cell bandwidth; x 2: cell downlink data transmission quantity/cell bandwidth; b 1: the uplink experience perception rate baseline value is equal to the uplink experience perception rate baseline of the modeling cell, a big packet b1 is 0.6Mbps, a middle packet b1 is 0.4Mbps, and a small packet b1 is 0.25 Mbps; b 2: a downlink experience perception rate baseline value is equal to a downlink experience rate baseline of a modeling cell, a big packet b2 is 3Mbps, a middle packet b2 is 2Mbps, and a small packet b2 is 1.5 Mbps; y 1: the cell uplink sensing experience rate; y 2: and (4) the cell downlink sensing experience rate.
Number of cell expansion carrier requirement (ROUNDUP ((f [ i ] [ j ]) -1,0) (2)
(3) Packet knapsack algorithm calculation example:
by using a packet knapsack algorithm, the capacity expansion carrier demand conditions of the middle packet cell 1 and the large packet cell 2 are calculated as follows:
sensing and judging a middle packet cell 1 and a big packet cell 2 according to a packet knapsack algorithm, wherein the uplink and downlink sensing experience rates of the cell 1 are both greater than the capacity of a knapsack, and capacity expansion is not needed; cell 2, below backpack capacity, brings a packet backpack algorithm to calculate carrier demand:
f[i][j]＝max([1.12/20/0.05],[9.58/20/0.4],[0.6/0.36],[3/0.67])＝1.12
the number of the capacity expansion carrier requirements of the cell 2 is equal to rounddup ((f [ i ] [ j ]) -1,0) is equal to 1. Therefore, the cell 2 needs to expand 1 20M carriers to meet the user's requirement for good sensing.
The embodiment of the invention improves the traditional user perception rate calculation method, takes the user perception rate containing the queuing delay of the first data packet as the judgment standard of the capacity expansion requirement of the current network, and is closer to the real requirement of the user; a packet knapsack algorithm is constructed, the capacity expansion requirements of the cells to be expanded of the large, medium and small bags of the existing network are quickly and accurately calculated by using the algorithm, and the capacity expansion requirement evaluation efficiency and accuracy of the existing network are improved; the method has the advantages that the method is based on the angle of the real perception experience of the user, the current network high-load cell to be expanded is evaluated, and the good internet experience of the user is met more directly; the grouping knapsack algorithm is utilized to quickly and accurately calculate the capacity expansion demand carrier number of the cell to be expanded, and capacity expansion resource waste caused by the traditional calculation of the capacity expansion carrier number is avoided.
