These drawings and the written description are not intended to limit the scope of the inventive concept in any way, but to illustrate the inventive concept to those skilled in the art by referring to the set embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
The development of network communication technology has led to the continuous emergence of various data services, and the demands of users for mobile data services have become more diversified. However, the mobile network can provide limited resources, and it is often impossible to ensure that all services can be performed at full speed at any time and any place, so that operators have to adopt a specific network guarantee policy to preferentially guarantee service awareness of high-level services and high-level users.
In order to guarantee high-level services preferentially, a common way is to classify different services in advance, and give different network resources, i.e. different quality of service (Quality of Service, qoS), to services with different priorities.
For example, mobile data services may be classified into the following categories according to requirements of different services on time delay, packet loss rate, transmission rate, and the like:
Session class: for example, services such as voice and video telephony, which are characterized by real-time, end-to-end, and small time delay, have symmetric or almost symmetric traffic flows up and down.
Interaction class: for example, services such as web browsing, database searching, online game, etc., generally refer to services in which terminals and servers perform online data interaction, and are characterized by modes of request and response.
Streaming media class: for example, users enjoy services such as audio or video programs on a network, which is characterized by real-time performance, but because the services are transmitted unidirectionally and do not need to be interacted, the real-time performance requirement is not as strict as that of session services, and a certain packet loss rate and packet error rate can be tolerated.
The background class: for example, receiving an email or a multimedia message, receiving a transmission file, downloading data, and the like. The method is characterized in that the user has no special requirement on the transmission time, but has high requirement on reducing the packet loss probability.
In network communication, when the network is overloaded or congested, to ensure that traffic of a certain type is not delayed or dropped, quality of service (Quality of Service, qoS) with different priority from other traffic is set for that traffic.
Common QoS configuration requirements are exemplified as follows:
For example: GBR refers to a constant allocation of bit rates to bearer requirements by the network, the corresponding bit rates being maintained even in case of network resources being strained.
Also for example: non-GBR, i.e. Non-GBR, means that the network does not provide the lowest transmission rate guarantee, and in case of congestion of the network, the traffic needs to withstand the requirement of reduced rate, and the Non-GBR bearer can be maintained for a long time because it does not occupy fixed network resources.
For another example: MBR (Maximum Bit Rate) defines the upper Rate limit that a certain service can reach under the condition of sufficient resources. The value of MBR is likely to be greater than or equal to the value of GBR.
Before opening each QoS service, the operator first determines the capacity of the wireless network for bearing the service, i.e. determines the number of users with set quality of service class which can be accommodated by the wireless network at present, in order to ensure the normal operation of the service. The determined capacity result can be used as a decision basis for immediately opening the service with the set quality of service class, and can be used as a guide basis for whether the capacity expansion operation of the network is required in advance or not. The reason is that if the service with the set quality of service class is opened by the reckless, the capacity of the service is not predetermined, and when the number of users with higher network resource consumption exceeds a certain limit, the quality of the service with the set quality of service class cannot be met, so that the network perception of the users with the specific quality of service class is deteriorated.
In the prior art, the capacity of a service with a set quality of service class is generally determined by theoretically calculating the maximum bearing capacity of a mobile communication system, and the capacity is calculated by acquiring the uplink/downlink peak rate of a user in the mobile communication system and by the uplink/downlink peak rate.
However, the capacity of the service with the set quality of service class determined by the prior art is larger than the actual capacity, and the result is not accurate enough.
This is because the distribution of users in the mobile communication network has randomness. For example, some users may be distributed closer to the base station, and such users may obtain higher uplink and downlink rate awareness while occupying relatively less system resources. But some other users may be distributed at a far distance from the base station, and these users are likely to occupy relatively more system resources, but the obtained uplink and downlink rates are low, because the coverage quality of the location signals where these users are located is poor, and the user plane data undergoes repeated retransmission and codec correction in the mobile communication system, so that the effective transmission rate is not high although a great deal of system resources are wasted. Therefore, it is not reasonable to estimate the number of users with a set qos class that can be accommodated in a cell according to the theoretically calculated cell limit capacity, but the actual capacity after the actual near, middle and far points of the users are distributed should be considered.
Although, at present, according to the actual distribution of the near, middle and far points of the user, a simulation model is established to determine the service capacity of the set service quality grade, for example, by establishing a mobile communication network model and a random distribution model of the user, the capacity of the set service quality grade is calculated in a simulation way.
However, the current simulation model has very complex building process, large simulation calculation amount, high calculation force requirement on a computer simulation system and inaccurate calculated simulation result.
In fact, most of services with QoS being opened have requirements on time delay and packet loss rate, and uplink and downlink guaranteed bit rates (Guaranteed Bit Rate, GBR) directly affect the size of the time delay and the size of the packet loss rate of the services, and the higher the uplink and downlink guaranteed bit rates, the smaller the time delay and the lower the packet loss rate. Therefore, determining the capacity of the wireless network for setting the service quality class service is a key link of determining the number of loadable users under the condition of guaranteeing the uplink/downlink guaranteed bit rate corresponding to the service quality class.
Therefore, in order to solve the above technical problems in the prior art, the present application provides a method, an apparatus, a device, and a medium for determining a service capacity, by acquiring a guaranteed bit rate GBR corresponding to a service with a set quality of service class of a cell, and according to the guaranteed bit rate GBR, acquiring a utilization rate of a communication resource of the cell or a busy hour average rate corresponding to a transmission in a highest time period of a service volume from a network management background of an operator. And then calculating the average actual maximum rate of cell transmission according to the average rate in busy hours, and determining the average capacity of the cell set service quality class service under the guaranteed bit rate GBR according to the average actual maximum rate. The network data is realized by acquiring the true realization network data, so that the determined capacity of the service with the set service quality grade is more accurate.
The application can be applied to the determination of mobile communication service capacity, wherein the mobile communication service can be a service with set service quality grade, such as IP telephone, video conference, video on demand, remote education and other multimedia real-time services, which are usually important services or key applications, and the priority allocation of network resources of the services is ensured by setting priority. It will be appreciated that the method for determining traffic capacity proposed by the present application includes, but is not limited to, the above scenario, and the listed scenario is not to be taken as limiting the present application.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a flow chart of a service capacity determining method according to a first embodiment of the present application, and as shown in fig. 1, the method may be performed by a service capacity determining device, for example, may be an operator server. The method specifically comprises the following steps:
S101, acquiring a guaranteed bit rate GBR corresponding to a cell set service quality class service.
In this embodiment, before acquiring data, the network system corresponding to the service is first clarified, for example, 3G, 4G, 5G, or the like. It should be noted that the time of the data acquired from the background of the operator network manager must be synchronous, and the data may be data in the same month or data in the same week.
The guaranteed bit rate GBR refers to the minimum bit rate at which the system guarantees the bearer, and the corresponding bit rate can be maintained even in case of network resources shortage. Which includes an upstream guaranteed bit rate GBR and a downstream guaranteed bit rate GBR.
S102, according to the guaranteed bit rate GBR, the busy hour average rate of the corresponding transmission of the cell communication resource utilization rate or the highest time period of the traffic is obtained from the background of the network management of the operator.
The average busy rate may be the average busy rate of the communication system of the operator, and the busy time refers to the time period when the local mobile communication network resource utilization rate or the traffic volume is maximum. The average rate of the busy hour of the cell may be taken, and the busy hour of the cell refers to a time period when each cell takes the resource utilization rate or the traffic volume of the cell to be maximum. The average rate in the busy hour of the system is obtained only by obtaining the average rate in the time period when the resource utilization rate or the traffic volume under the system is maximum because the average rate in the time period when the resource utilization rate or the traffic volume of each cell is maximum does not need to be obtained, so that the average rate in the busy hour of the system is more convenient and faster than the average rate in the busy hour of the cell. The busy hour average rate includes an uplink busy hour average rate and a downlink busy hour average rate.
Illustratively, the acquisition procedure is described with the uplink busy hour average rate as an example. And obtaining the uplink busy hour rate of each cell in the selected area from the background of the network management of the operator, and adding the uplink busy hour rates of all the cells to divide the sum by the number of the cells to obtain the uplink busy hour average rate of each cell. The method for obtaining the average speed in the downlink busy hour is the same as that in the uplink busy hour, and the application is not repeated.
S103, calculating the average actual maximum rate of the cell transmission according to the average rate in busy hours.
And S104, determining the average capacity of the cell set service quality grade service meeting the guaranteed bit rate GBR according to the average actual maximum rate.
According to the obtained guaranteed bit rate GBR corresponding to the cell set service quality grade service, determining the average capacity of the cell set service quality grade service, and specifically:
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the uplink guaranteed bit rate GBR, the capacity of the cell set service quality class service is the uplink average capacity of the cell.
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the downlink guaranteed bit rate GBR, the capacity of the cell set service quality class service is the downlink average capacity of the cell.
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is an uplink guaranteed bit rate GBR and a downlink guaranteed bit rate GBR, the capacity of the cell set service quality class service is the minimum capacity of the uplink average capacity and the downlink average capacity of the cell.
In the above embodiment of the present application, the guaranteed bit rate GBR corresponding to the service of the cell set quality of service class is obtained, and the busy hour average rate corresponding to the transmission of the highest time period of the cell communication resource utilization rate or the traffic is obtained from the background of the network manager according to the guaranteed bit rate GBR. And then calculating the average actual maximum rate of cell transmission according to the average rate in busy hours, and determining the average capacity of the cell set service quality class service under the guaranteed bit rate GBR according to the average actual maximum rate. The network data is realized by acquiring the true realization network data, so that the determined capacity of the service with the set service quality grade is more accurate.
Further, on the basis of the first embodiment, a detailed description will be given below of the determination process of the average capacity of the cell-set quality of service class traffic under the condition that the guaranteed bit rate GBR is satisfied, with reference to the embodiments shown in fig. 2 and 3, respectively.
In one embodiment:
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the downlink guaranteed bit rate GBR, the capacity of the cell set service quality class service is the downlink average capacity of the cell.
As shown in fig. 2, fig. 2 is a flowchart of a method for determining an average capacity of a service with a set quality of service class of a cell according to a second embodiment of the present application, where the method includes the following steps:
s201, obtaining a downlink guaranteed bit rate GBR corresponding to a cell set service quality class service.
S202, according to the downlink guaranteed bit rate GBR, obtaining the cell communication resource utilization rate or the downlink busy hour average rate corresponding to the highest traffic volume time period from the background of the network manager.
S203, calculating the downlink average actual maximum rate of the cell transmission according to the downlink busy hour average rate.
In particular, the method comprises the steps of,
Calculating the downlink average actual maximum rate of cell transmission by using the following formula (1):
QD＝λ×RD (1)
Wherein Q D is the downlink average actual maximum rate of cell transmission; r D is the average rate in the downlink busy hour; lambda is the average number of users active simultaneously while busy.
It should be noted that, in order to improve the accuracy of the capacity determination of the present application, the average number of simultaneous active users used must be the number of users that are strictly transmitting data simultaneously. For example, in the third generation mobile communication (3rd Generation,3G)/fourth generation mobile communication (4th Generation,4G)/fifth generation mobile communication (5th Generation,5G) mobile network system, the average number of simultaneous activation users must be the average of the number of users that are synchronized for data transmission on a time granularity of time slots (e.g., 1 slot of 4G for 0.5 ms).
The average number of users activated simultaneously in busy hours λ can be directly obtained from the carrier network management background, but due to the difference of the mobile communication devices, if the devices cannot directly obtain λ, more common radio resource control (Radio Resource Control, RRC) connection user number and user activation ratio two key performance indexes KPI (Key Performance Indicator) can also be extracted from the carrier network management background for calculation.
Calculating the average number of simultaneous active users in the downlink busy hour of the cell by using the following formula (2):
λ＝μ×α (2)
Wherein mu is the average RRC connection user number of the busy cell; alpha is the average user activation ratio of the busy cell. It should be noted that if μ is a non-integer, the corresponding integer may be obtained by rounding down, and if α is a non-integer, λ may be calculated by substituting the above formula (2), and rounding down.
Taking a 4G network as an example, the average activation ratio of busy hours of 4G network users in different areas or different cells in the same area is different, but the average activation ratio is generally between 8% and 20%, and an operator can take a value according to the actual situation of an evaluation area.
S204, determining the downlink average capacity of the cell set service quality class service under the downlink guaranteed bit rate GBR according to the downlink average actual maximum rate.
In particular, the method comprises the steps of,
Calculating the downlink average capacity of the cell set quality of service class service by using the following formula (3):
Wherein, C D sets the downlink average capacity of the service quality grade service for the cell; sign symbol Representing a downward rounding; r DG is the downstream guaranteed bit rate.
In the above embodiment of the present application, the downlink guaranteed bit rate GBR corresponding to the service with the set quality of service class of the cell is obtained, and the downlink busy hour average rate corresponding to the cell communication resource utilization rate or the highest time period of the service volume is obtained from the background of the network manager according to the downlink guaranteed bit rate GBR. And then calculating the downlink average actual maximum rate of cell transmission according to the downlink busy hour average rate, and further determining the downlink average capacity of the cell set service quality class service under the downlink guaranteed bit rate GBR. According to the method, the network data are realized by obtaining the true realization network data, so that the determined downlink average capacity of the service with the set service quality level is more accurate.
In another embodiment:
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the uplink guaranteed bit rate GBR, the capacity of the cell set service quality class service is the uplink average capacity of the cell.
As shown in fig. 3, fig. 3 is a flowchart of another method for determining an average capacity of a cell set qos class service according to a third embodiment of the present application, where the method includes the following steps:
S301, obtaining an uplink guaranteed bit rate GBR corresponding to a cell set service quality class service.
S302, according to the uplink guaranteed bit rate GBR, the uplink busy hour average rate of the corresponding transmission of the cell communication resource utilization rate or the highest traffic volume time period is obtained from the background of the network manager of the operator.
S303, calculating the uplink average actual maximum rate of the cell transmission according to the uplink busy hour average rate.
In particular, the method comprises the steps of,
Calculating the uplink average actual maximum rate of cell transmission by using the following formula (4):
QU＝λ×RU (4)
Wherein Q U is the uplink average actual maximum rate of cell transmission; r U is the average rate in the uplink busy hour; lambda is the average number of users activated simultaneously in busy hours, and the value of lambda can be directly obtained from the background of the network management of the operator, or can be obtained through a formula II, and the method of obtaining through the formula II is the same as that in the embodiment II, and repeated description is omitted here.
S304, determining the uplink average capacity of the cell set service quality grade service meeting the uplink guaranteed bit rate GBR according to the uplink average actual maximum rate.
Calculating the uplink average capacity of the cell set quality of service class service by using the following formula (5):
Wherein, C U sets the uplink average capacity of the service quality grade service for the cell; sign symbol Representing a downward rounding; r UG is the uplink guaranteed bit rate.
It should be specifically noted that, in reality, users in the existing network mainly use downlink traffic services, such as video services and web browsing services, and the demands of uplink transmission of users are less, uplink transmission data also mainly use small packets, and uplink rate values extracted from the background of the operator network manager are generally smaller, so that the real uplink guaranteeing capability of the mobile communication system cannot be reflected.
Therefore, the downlink rate extracted from the network management background is generally larger than the uplink rate reference value, when the uplink average capacity of a single cell of the service with the set service quality level is required to be estimated, the uplink guaranteed bit rate can be converted through the downlink equivalent guaranteed bit rate according to the principle of the mobile communication system, and then the equivalent estimation is carried out according to the method for calculating the downlink average capacity of the cell of the service with the set service quality level.
The method of equivalent conversion of the uplink guaranteed bit rate through the downlink equivalent guaranteed bit rate is various, and the present application is only an exemplary scheme provided below, and is not limited by the present application.
In general, in a mobile communication system, a theoretical downstream peak rate is higher than a theoretical upstream peak rate, for example, the downstream peak rate is n times the upstream peak rate, where n is equal to or greater than 1. Therefore, the uplink average capacity of the cell-set quality of service class traffic can be calculated using the following formula (6):
Wherein, C U sets the uplink average capacity of the service quality grade service for the cell; lambda is the average number of users activated simultaneously when busy; r D is the average rate in the downlink busy hour; r DEG is the downstream equivalent guaranteed bit rate GBR, where R DEG＝RUG×n,RUG is the upstream guaranteed bit rate R UG; n is a proportionality coefficient, and n is more than or equal to 1; therefore, the above formula (6) may be
In summary, by means of the conversion of the downlink equivalent guard bit rate, the uplink average capacity of the cell set service quality class service under the uplink guard bit rate GBR can be obtained.
In the above embodiment of the present application, the uplink guaranteed bit rate GBR corresponding to the service of the cell set quality of service class is obtained, and according to the uplink guaranteed bit rate GBR, the uplink busy hour average rate corresponding to the cell communication resource utilization rate or the highest time period of the service volume is obtained from the background of the network manager. And then calculating the uplink average actual maximum rate of cell transmission according to the uplink busy hour average rate, and determining the uplink average capacity of the cell set service quality class service under the uplink guaranteed bit rate GBR according to the uplink average actual maximum rate. Or obtaining the uplink average capacity of the cell set service quality grade service under the uplink guaranteed bit rate GBR through the downlink equivalent guaranteed bit rate conversion. According to the method, the uplink average capacity of the determined service with the set service quality level is more accurate by acquiring the true realization network data.
It can be understood that, through the above embodiments one to three, the average capacity of the cell set qos class service satisfying the guaranteed bit rate, that is, the number of set qos class service users satisfying the set GBR requirement, which can be carried by one cell at the maximum, can be obtained. Further, according to the average capacity of the single cell, the total capacity of the service with the set quality of service grade in the target area containing the cell can be determined.
In particular, the method comprises the steps of,
The total number of cells in the target area is obtained, wherein the target area must contain the calculated average capacity of the service of the set quality of service class of a certain cell.
And determining the total capacity of the set service quality grade service of the certain cell in the target area according to the determined average capacity of the set service quality grade service of the certain cell and the total number of the cells in the target area.
The total capacity of the set quality of service class traffic within the target area is calculated using the following equation (7):
Wherein C SD is the total capacity of the set quality of service class service in the target area satisfying the guaranteed bit rate GBR; k is the number of cells in the target area; beta is any real number in the (0, 1) range, and the specific value can be determined according to the actual situation, taking into account the capacity loss coefficient caused by overlapping coverage between cells in the geographic range.
If the total capacity of the set qos class service under the uplink guaranteed bit rate GBR is required to be satisfied in the target area, then C is the uplink average capacity of the set qos class service of the cell included in the target area; if the total capacity of the set service quality class service under the downlink guaranteed bit rate GBR is required to be met in the target area, C is the downlink average capacity of the set service quality class service of the cell contained in the target area; if the requirement in the target area satisfies both the uplink guaranteed bit rate GBR and the total capacity of the set quality of service class service under the downlink guaranteed bit rate GBR, then C is the minimum value of the uplink average capacity and the downlink average capacity of the set quality of service class service of the cell included in the target area.
In principle, each cell of a mobile communication system is responsible for covering a certain geographical area, and in order to provide a seamless mobile experience for a user, a part of the area must be overlapped between the cells to ensure that voice or data service is not interrupted when the user moves between the cells. Empirically, the beta value is typically between 0.01 and 0.05, but is also affected by the specific weight coverage definition method. Of course, β may also be an overlap coverage value common in the communications industry, and since the overlap coverage index does not belong to the research emphasis of the present application, reference may be specifically made to the related art, and the present application will not be described in detail.
It should be noted that the total capacity of the service meeting the set quality of service class at the guaranteed bit rate GBR calculated according to the above method is the limit capability of the network in the target area in the actual situation, and is the upper limit of the number of users accommodating the type of service, and the actual situation includes the actual situation of network coverage, the actual situation of user distribution, the actual situation of service type distribution, and the like. In general, the user who sets the qos class service does not suggest approaching or reaching the upper limit, because the user who sets the qos class has the ability to preempt resources, and once approaching or reaching the upper limit, the user's network perception will be severely degraded and even unable to access the network, thereby causing complaints of the user. The capacity determination result of the application has important reference significance for operators to control the user scale of the service with the set service quality level and ensure the legal rights and interests of people.
Further, in order to facilitate understanding of the method according to any one of the first to third embodiments, a method for determining a set quality of service class traffic capacity will be described in detail below with reference to a specific fourth embodiment.
For example, if an operator needs to determine the capacity of a service with a set quality of service class in a certain area, the maximum number of users of the type of service that can be carried in the area is determined. If the downlink guaranteed bit rate of the user with the set service quality level is 2Mbps, the uplink guaranteed bit rate is 1Mbps. The average number of users activated simultaneously when the cells in the average area are busy is known to be 20, the average downlink rate in busy is 5Mbps, and the average uplink rate in busy is 0.5Mbps.
According to the above formula (1) and formula (3), the downlink average capacity of the cell set qos class service satisfying the downlink guaranteed bit rate can be calculated.
First, the downlink average actual maximum rate of cell transmission is calculated using the following formula:
QD＝λ×RD＝20×5＝100Mbps
then, the downlink average capacity of the cell set quality of service class service is calculated using the following formula:
According to the above formula (4), formula (5) and formula (6), the uplink average capacity of the cell set qos class service satisfying the uplink guaranteed bit rate can be calculated:
one possible implementation is:
First, the uplink average actual maximum rate of cell transmission is calculated using the following formula:
QU＝λ×RU＝20×0.5＝10Mbps
Then, the uplink average capacity of the cell set quality of service class service is calculated using the following formula:
another possible implementation is:
by converting the uplink guaranteed bit rate through the downlink equivalent guaranteed bit rate, according to the proportional relation between the uplink and downlink guaranteed bit rates, assuming that the downlink guaranteed bit rate is 3 times of the uplink guaranteed bit rate, the uplink average capacity of the cell set service quality class service is obtained by the following calculation:
further, in this embodiment, the average capacity of the cell set qos class service under the downlink guaranteed bit rate is 50, and the average capacity of the cell set qos class service under the uplink guaranteed bit rate is 33, which is taken as an example, and the average capacity of the cell set qos class service is determined.
In particular, the method comprises the steps of,
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the downlink guaranteed bit rate GBR, the capacity of the cell set service quality class service is 50 downlink average capacities of the cells.
If the guaranteed bit rate GBR corresponding to the acquired cell set service quality class service is the uplink guaranteed bit rate GBR, the capacity of the cell set service quality class service is 33 uplink average capacities of the cells.
If the guaranteed bit rate GBR corresponding to the acquired cell set qos class service is an uplink guaranteed bit rate GBR and a downlink guaranteed bit rate GBR, the average capacity C of the set qos class service of the cell included in the target area is the smallest capacity of the uplink average capacity and the downlink average capacity of the cell, that is, c=min (50, 33) =33. Wherein, min (·) represents the minimum value of the two.
Further, after determining the average capacity of the set qos class service of a single cell, determining the total capacity of the set qos class service in the target area including the cell.
For example, assuming that the target area requires both an uplink guaranteed bit rate for guaranteeing cell transmission and a downlink guaranteed bit rate for guaranteeing cell transmission, the number of cells included in the target area is 1000, and the capacity loss coefficient β is 0.016, according to the above formula (7), it can be determined that the total capacity of the service set to the quality of service class in the target area is:
therefore, the total capacity of the set qos class service in the target area is 32840 users with set qos class.
