Description
Technical Field
The present application relates to the field of communications, and in particular, to a network capacity expansion method and an access network device.
Background
When an existing network cannot meet the increasing service demand, capacity expansion of the existing network is required. For example, when the data transmission rate (hereinafter referred to as peak data transmission rate) when the traffic volume is maximum is less than the minimum data transmission rate required by all the services in a specified time period, and the resource occupancy rate in the specified time period is greater than or equal to a preset resource occupancy threshold, the capacity of the existing network is expanded. In practical applications, the average data transmission rate in the specified time period is usually used as a judgment basis.
However, since the traffic volume is dynamically changed, the average data transmission rate and the peak data transmission rate inevitably have a deviation, so that the accuracy of determining whether the existing network needs to be expanded based on the average data transmission rate is poor. For example, when the peak data transmission rate is greater than or equal to the required minimum data transmission rate, and the average data transmission rate is less than the required minimum data transmission rate, an error conclusion that the existing network that does not need capacity expansion needs capacity expansion is reached. Therefore, how to obtain the peak data transmission rate of the existing network as accurately as possible becomes a problem to be solved urgently.

The network capacity expansion method provided in this embodiment may be applied to the communication network 10 shown in fig. 1, where the communication network 10 may be a fifth generation (5th generation, 5G) mobile communication network, and may also be a fourth generation (4th generation, 4G) (e.g., an Evolved Packet System (EPS) mobile communication network, and may also be other actual mobile communication networks, and the present application is not limited thereto.
As shown in fig. 1, the communication network may comprise: terminal 11, access network equipment 12 and core network 13. The terminal 11 in fig. 1 may be configured to connect to an access network device 12, such as a base station deployed by an operator, through a wireless air interface, and then access to a core network 13; the access network device 12 is mainly used for implementing functions of a wireless physical layer, resource scheduling and wireless resource management, wireless access control and mobility management; the core network 13 may include network devices (e.g., servers, routers, etc.), and the core network 13 is used for providing data services for the terminal devices. It should be noted that fig. 1 is only an exemplary architecture diagram, and the network architecture may include other functional units besides the functional units shown in fig. 1, which is not limited in this application.

An embodiment of the present application provides a network capacity expansion method, as shown in fig. 2, the method may include S201 to S205:
s201, the access network equipment acquires a data transmission time period in a specified time period.
The access network device may be the access network device 12 shown in fig. 1, and the terminal transmits data and signaling between the access network device and the core network. The specified period of time may be set to a period of time where traffic is large. For example, it may be set to be 7:00 to 9:00 peak hours on working days or a prime time period of an important festival.
In practical applications, the specified time period may be divided into one or more data transmission time periods according to the time distribution of the traffic in the specified time period, where each data transmission time period includes a transmission time interval TTI. The TTI is a basic time unit that can be allocated by an existing network and is used for carrying one transport layer packet. For example, in a Universal Mobile Telecommunications System (UMTS) network and a Long Term Evolution (LTE) network, a TTI is one Subframe (Subframe) and a time length is 1 ms.
S202, the access network equipment determines data transmission time according to the data transmission time period, wherein the data transmission time is the time length obtained by summing all data transmission time periods in the appointed time period after deducting the last TTI in each data transmission time period.
S203, the access network equipment determines the user perception rate.
The user perception rate is the ratio of data transmission flow and data transmission time in the data transmission time.
In practical applications, a large data packet is usually split into a plurality of smaller data packets (hereinafter referred to as split packets), and the smaller data packets are respectively carried in different TTIs for transmission. According to the protocol, the capacity of the split packet carried in the last TTI is usually smaller than the capacity of the split packet carried in the TTI before the last TTI, that is, the split packet carried in the last TTI usually does not affect the smoothness of the service data transmission. Therefore, the data transmission time and the data transmission flow counted in the embodiment of the present application are values obtained by subtracting the last TTI, so that the counted user sensing rate is closer to the peak data transmission rate in the specified time period.
And S204, the access network equipment determines the resource occupancy rate according to the quantity of the distributed data transmission resources and the total quantity of the distributed data transmission resources in the specified time period.
Optionally, the access network device calculates the resource occupancy rate according to the allocated data transmission resource quantity and the allocable data transmission resource total quantity. The resource occupancy rate is a ratio of the number of the allocated data transmission resources to the total number of the allocable data transmission resources.
Optionally, the access network device determines the resource occupancy rate according to the number of the allocated data transmission resources, the total amount of the allocable data transmission resources, the data transmission time occupancy rate and a preset data transmission time occupancy rate threshold; the data transmission time ratio is the ratio of the data transmission time to the specified time period.
Specifically, if the data transmission time occupation ratio is greater than or equal to the data transmission time occupation ratio threshold, the access network device calculates the resource occupation ratio according to the following formula according to the allocated data transmission resource quantity, the allocable data transmission resource total quantity and the data transmission time occupation ratio;
wherein gamma is the resource occupancy rate, RusedFor the allocated amount of data transmission resources, Rtotalτ is the data transmission time ratio, which is the total amount of allocable data transmission resources.
Specifically, if the data transmission time ratio is smaller than the data transmission time ratio threshold, the access network device calculates the resource occupancy rate according to the following formula according to the allocated data transmission resource quantity, the allocable data transmission resource total quantity and the data transmission time ratio threshold;
wherein, is resource occupancy, RusedFor the allocated amount of data transmission resources, RtotalFor the total amount of allocable data transmission resources, Ttime_thrThe service data transmission time is a threshold value.
In practical application, the resources of the access network device may include air interface resources that can be used for data transmission by the access network device, and the air interface resources that can be used for data transmission may include time domain resources, frequency domain resources, code domain resources, and the like of the access network device. For example, for an LTE access network device, the time domain Resource may include a radio Frame (Frame), a subframe, and the like that can be allocated in a specified time period, and the frequency domain Resource may include the number of central carriers and the number of Physical Resource Blocks (PRBs) that can be allocated in a specified time period. For another example, for a Wideband Code Division Multiple Access (WCDMA) Access network device, the time domain resources may include radio frames (frames), subframes, and the like that can be allocated within a specified time period, the frequency domain resources may include the number of center carriers that can be allocated within a specified time period, and the like, and the Code domain resources may include the number of pseudorandom codes that can be allocated within a specified time period, the number of Orthogonal Variable Spreading Factor (OVSF) codes, and the like.
Specifically, in this embodiment of the present application, the number of used resources in the specified time period may be the number of empty resources that have been allocated by the access network device for transmitting the service data.
It should be noted that, for the occupation situations of the different types of air interface resources, statistics may be performed respectively, and the occupancy rate of each type of air interface resource may be calculated respectively.
S205, if the resource occupancy rate is greater than or equal to a preset resource occupancy rate threshold value, and the user perception rate is less than or equal to a preset rate threshold value, the access network equipment outputs a network capacity expansion indication.
Both the data transmission time ratio threshold and the rate threshold can be preset according to actual conditions. For example, the resource occupancy threshold and the rate threshold may be set according to the statistical analysis result of the processing capacity and the traffic of the existing network and on the basis of a certain margin.
The access network equipment outputs network capacity expansion indication, including but not limited to output report in various forms of characters, pictures, audio, video, paper and the like and/or alarm indication in various forms of characters, pictures, audio, light and the like, which are output by output devices such as a display device, a printing device, an alarm device and the like of the access network equipment.
It should be noted that S204 may be executed before S201 to S203, or may be executed after S201 to S203, which is not limited in this embodiment. Preferably, S204, and S201-S203 may be performed simultaneously.
Taking an LTE network as an example, as shown in table 1, illustratively, the specified time period is set to 1 hour, the downlink PRB occupancy threshold is set to 60%, and the downlink user perceived rate threshold is set to 5 megabits per second (Mbps).
TABLE 1
| Access network device name | 1 hour downlink PRB occupancy rate | 1 hour downlink user perception rate |
| Access network device 1 | 75.4％ | 2.3Mbps |
| Access network device 2 | 60.1％ | 8.1Mbps |
| Access network device 3 | 15％ | 3.5Mbps |
| Access network device 4 | 5％ | 25.9Mbps |
The downlink PRB occupancy rate of the access network equipment 1 is 75.4%, is greater than the threshold value of the downlink PRB occupancy rate, and the downlink user perception rate of the access network equipment is 2.3Mbps and is less than the threshold value of the downlink user perception rate by 5Mbps, thereby meeting the capacity expansion condition and requiring capacity expansion. Other access network devices do not meet the capacity expansion condition and do not need capacity expansion.
TABLE 2
Illustratively, as shown in table 2, the specified time period is set to 1 hour, the downlink PRB occupancy threshold is set to 70%, the data transmission time occupancy threshold is set to 80%, and the downlink user perceived rate threshold is set to 5 megabits per second (Mbps).
The data transmission time of the access network device 6 is 60% and is less than the data transmission time threshold of 80%, so that the occupancy rate of the downlink PRB after the access network device 6 is converted is: the actual downlink PRB occupancy rate/data transmission time ratio threshold value is 65%/80%/81.25%, is greater than the downlink PRB occupancy rate threshold value by 70%, and the downlink user perception rate of the access network device is 1.3Mbps, is less than the downlink user perception rate threshold value by 5Mbps, satisfies the capacity expansion condition, and needs capacity expansion. The data transmission time of the access network device 8 is 90% and is greater than the data transmission time by 80% of the threshold, so the occupancy rate of the downlink PRB after the access network device 8 is reduced is: the actual ratio of the downlink PRB occupancy rate to the data transmission time is 70%/90%/77.8%, which is greater than the threshold value of the downlink PRB occupancy rate by 70%, however, the downlink user perception rate of the access network device is 11.9Mbps, which is greater than the threshold value of the downlink user perception rate by 5Mbps, which does not satisfy the capacity expansion condition and does not need capacity expansion. In addition, the access network devices 5 and 7 do not meet the capacity expansion condition, and the capacity expansion is not needed.
The network capacity expansion method provided by the embodiment of the application can divide the designated time period into at least one data transmission time period, acquire the data transmission time and the data transmission flow in the designated time period on the basis of deducting the data transmission flow in the last TTI and the last TTI in each data transmission time period, and determine the user perception rate according to the acquired data transmission time and data transmission flow, so that the situation that the user perception rate is calculated by using the data transmission flow in the last TTI and the last TTI in each data transmission time period is avoided, the accuracy of calculating the user perception rate is improved, and the accuracy of network capacity expansion evaluation is improved.
