Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for evaluating a transmission bandwidth of a PTN access loop.
Background
In recent years, mobile communication technology continues to be developed vigorously, wherein Time Division long term Evolution (TD-LTE) is developed more rapidly, and currently, established 4G base stations achieve continuous coverage of most cities and counties and hot spot coverage of developed towns, 4G terminal users are greatly increased, and Average monthly Per-User traffic consumption (DoU) and Average Revenue Per User (ARPU) of users are also greatly increased. In this case, it is more necessary to ensure the network quality, ensure the quality of various services, and attract more users.
In an actual TD-LTE networking environment, considering comprehensively from factors such as cost and utilization rate, the transmission bandwidth allocated to the base station by the transmission Network deployed by an operator cannot be supplied in an unlimited amount, so that reasonable allocation of access bandwidth to the base station and a Packet Transport Network (PTN) connected to the base station is very critical to user service experience, that is, it is to be ensured that a VIP base station and a VIP service can enjoy sufficient bandwidth, and a low-priority base station or a service cannot be in a bandwidth starvation state. The transmission bandwidth parameters mainly include Committed Information Rate (CIR) and Peak Information Rate (PIR), which are also referred to as guaranteed bandwidth and Peak bandwidth, respectively, the former is an independent bandwidth, the latter is a shared bandwidth, and the transmission bandwidth of the base station is mainly configured with the two parameters. When the Transmission bandwidth is insufficient, unreliable services of a User Data Protocol (UDP) are randomly lost, the service is decelerated, and a large amount of out-of-order, packet loss and retransmission phenomena are generated for reliable services of a Transmission Control Protocol (TCP), so that a server triggers a related TCP congestion mechanism according to the specification of the TCP, a congestion window is reduced, TCP Data are retransmitted, and the download rate is influenced. Therefore, allocating a reasonable transmission bandwidth to the base station is very important to guarantee the user service experience, which requires pre-evaluation of the transmission bandwidth requirement on the PTN access ring.
At present, the TD-LTE transmission networking mainly uses an L3PTN access method, and in the whole transmission path: the PTN access ring-PTN convergence layer-L3 PTN configures transmission bandwidth for the base station.
In the prior art, a method for evaluating the transmission bandwidth requirement of a PTN access ring is to evaluate the air interface bandwidth of a base station and convert the air interface bandwidth into an air interface rate. The method specifically comprises the following steps:
the air interface service bandwidth of the base station is max (cell average rate x n, peak rate), where n is the number of cells included in the base station, that is, it is ensured that each cell of a site reaches the average rate at the same time, or it is ensured that one cell reaches the peak rate, and the transmission bandwidth requirement of the base station is CIR, that is, it is ensured that the bandwidth. Then, the transmission bandwidth of the whole station is 1.05 × 1.05+5 of the air interface service bandwidth, which is specifically referred to table 1:
TABLE 1
(entire station transmission bandwidth calculating method)
For example, as shown in Table 2,
TABLE 2
(example of parameters of the entire station)
Then the whole station transmission bandwidth is 1.05 × 1.05+5 ═ 270 × 1.05+5 ═ 302M. Calculating for 5-8 base stations of one PTN access ring, the transmission bandwidth required by the PTN access ring through air interface translation is 5 × 302M 1510M, and obviously, the bandwidth of the conventionally configured 1G PTN access ring cannot meet the requirement.
Therefore, the transmission bandwidth converted from the base station air interface is large, so that the actual physical bandwidth of the PTN cannot meet the requirement. Through research and statistics, the CIR configuration of the PTN is more than 20-40M in practice, but the CIR configuration on the PTN is smaller in practice, and the requirement of a base station cannot be really met. The PIR on the PTN can consider preemption, but whether the PIR can preempt the preemption or not has uncertainty, so that the CIR bandwidth estimation adopting the air interface conversion has no practical popularization significance in estimating the transmission bandwidth requirement of the PTN access ring.
In the prior art, another method for evaluating the transmission bandwidth requirement of the PTN access ring is to obtain the requirement through a transmission bandwidth occupation monitoring function provided by the PTN access ring in an individual region.
However, the monitoring function is that a transmission manufacturer deploys on the transport layer PTN side, and after investigation, the transmission manufacturer is generally not started, and in general, a wireless manufacturer cannot directly coordinate to the transmission manufacturer to coordinate to locate, and can only submit an analysis report request to the operator for configuration of the transmission manufacturer.
Therefore, when the service transmission rate cannot be expected, the base station can only eliminate the quality of an air interface, grab a service message packet from between the base station and the core network, and confirm the transmission quality to evaluate the transmission bandwidth requirement.
Therefore, in the prior art, when the requirement of the transmission bandwidth of the PTN ring is evaluated, the transmission bandwidth can be evaluated only through an air interface at the base station side, but the result of the air interface evaluation does not meet the actual requirement.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem that the transmission bandwidth cannot be effectively evaluated at the base station side in the prior art, in the embodiment of the invention, for the PTN access ring to be analyzed, the network management equipment counts the received downlink transmission rates reported by all base stations on the PTN access ring, calculates the downlink super-bandwidth frequency value of the PTN access ring, and evaluates whether the transmission bandwidth of the PTN access ring meets the requirement or not.
The present invention will be described in detail with reference to specific examples, but it is to be understood that the present invention is not limited to the examples.
In practice, at present, the transmission bandwidth of the uplink service is not limited, and the situation of insufficient transmission bandwidth generally does not occur, so the embodiment of the present invention is mainly performed for the downlink transmission bandwidth, and of course, with the increase of the uplink service, if the uplink transmission bandwidth needs to be evaluated, the method of the embodiment of the present invention may also be applied.
Referring to fig. 1, in the embodiment of the present invention, a specific flow of a method for evaluating a transmission bandwidth of a PTN access loop is as follows:
step 100: and the network management equipment determines the PTN access ring to be analyzed.
When the transmission bandwidth is limited, the service transmission rate is reduced, or a large amount of phenomena of packet loss, disorder and retransmission occur during network packet capture, in practice, generally when these phenomena occur, the problem needs to be positioned and analyzed, and whether the transmission bandwidth is limited needs to be evaluated.
In practical application, the network management device may provide a monitoring switch for determining whether the transmission bandwidth of the PTN access ring needs to be evaluated, and the user may start the monitoring switch as needed. In addition, in general, the occupied busy hour transmission bandwidth is large, and the occupied whole busy hour data transmission bandwidth is stable, so that the busy hour data transmission bandwidth is monitored only in a certain time period.
When step 100 is executed, the following two ways can be adopted, but not limited to:
the first mode is as follows: and searching a PTN access ring associated with the target base station according to the target base station selected by the user, and taking the associated PTN access ring as the PTN access ring to be analyzed.
The network management equipment supports the association relationship between the online adding base station and the PTN access ring and supports the functions of automatic archiving, inquiring, modifying, deleting and data exporting, so that if only the target base station is known, the network management equipment can automatically search the PTN access ring associated with the target base station and all other base stations under the PTN access ring, and further determine the PTN access ring to be analyzed.
The second mode is as follows: and directly accessing the PTN selected by the user into the ring as the PTN access ring to be analyzed.
If the PTN access ring to be analyzed is known, the user can directly select the PTN access ring, the network management equipment can use the PTN access ring selected by the user as the PTN access ring to be analyzed, and then all base stations on the PTN access ring can be automatically searched.
Further, the network management device displays the determined PTN access ring to be analyzed and all base stations on the PTN access ring, and adjusts the base stations on the PTN access ring according to the user instruction, so that the user can visually understand and analyze the information, for example, the user can add or delete the base stations on the PTN access ring on line according to the actual situation and the base stations displayed on the PTN access ring.
Step 110: and in a preset monitoring time, the network management equipment calculates a downlink super bandwidth frequency value of the PTN access ring according to a preset transmission bandwidth threshold value and the received downlink transmission rate reported by all base stations on the PTN access ring.
The monitoring time can be preferably set to a certain period of time in busy hour, so that the occupied transmission bandwidth in busy hour is large, and the occupied data transmission bandwidth in the whole busy hour is stable. Moreover, since the theoretical bandwidth of the PTN access ring in TD-LTE is generally 1000M, and the conventional maximum available physical bandwidth is 850M, the threshold value of the transmission bandwidth may be preferably set to be slightly smaller than the maximum available physical bandwidth, for example, 750M, and may be specifically set as needed.
When step 110 is executed, the method specifically includes:
firstly, within the preset monitoring time, according to the preset base station reporting time, calculating the sum of downlink transmission rates according to the downlink transmission rates reported by all base stations on the PTN access ring; and the reporting time of the base station is less than the monitoring time.
Then, screening all downlink transmission rate sums which are larger than a preset transmission bandwidth threshold value from all downlink transmission rate sums obtained according to the reporting time of the base station, and counting a first number of the screened downlink transmission rate sums and a second number of the unsensed downlink transmission rate sums.
The method specifically comprises the following steps: judging whether the calculated downlink transmission rate and the calculated downlink transmission rate are larger than a preset transmission bandwidth threshold value every time according to the reporting time of the base station, if so, recording as 'the threshold value of the super transmission bandwidth occurs for 1 time', otherwise, recording as 'the threshold value of the super transmission bandwidth occurs for 0 time';
adding up all times of the cumulative addition of the times of the occurrence of the threshold value of the 1-time super transmission bandwidth, and taking the sum of the times of the cumulative addition of the times of the occurrence of the threshold value of the 1-time super transmission bandwidth as a first number; and cumulatively adding all of the times noted as "0 times of occurrence of the HyperTransport Bandwidth threshold", and taking the sum of the cumulatively added times noted as "0 times of occurrence of the HyperTransport Bandwidth threshold" as the second number.
And finally, calculating the first number and the ratio of the sum of the first number and the second number, and taking the ratio as the downlink super bandwidth frequency value of the PTN access ring.
For example, if the preset first period is 1 hour, the preset second period is 1 second, and the preset transmission bandwidth threshold is 750M, the network management device performs statistics once every 1 second within 1 hour, 3600 times of statistics are required, and if the network management device performs statistics for the last time to obtain the number of times exceeding 750M is 1000 times, and the number of times not exceeding 750M is 3500 times, the downlink super bandwidth frequency value of the PTN access ring is 1000/3600-28%.
It should be noted that all base stations on the PTN access ring are preferably products of the same manufacturer, so as to ensure uniform analysis behavior, and analysis needs to be performed according to all base stations on the same PTN access ring, otherwise, analysis is not accurate, and base stations of different manufacturers can be distinguished by regions at present.
Step 120: and when the network management equipment determines that the downlink super bandwidth frequency value is not less than a preset super bandwidth alarm threshold value, determining that the transmission bandwidth of the PTN access ring is insufficient, and alarming.
According to step 110, for example, if the preset ultra-bandwidth alarm threshold value is 20%, and the calculated downlink ultra-bandwidth frequency value 28% of the PTN access ring is greater than 20%, it is determined that the transmission bandwidth of the PTN access ring is insufficient, and an alarm is performed, so that the operation and maintenance staff can coordinate according to the alarm information to expand the transmission bandwidth of the PTN access ring.
Therefore, whether the transmission bandwidth is limited or not is evaluated by analyzing the occupation condition of the transmission bandwidth of the base station on the PTN access ring, when the service rate is lower, whether the transmission bandwidth resources on the PTN access ring are enough or not can be directly evaluated from the base station side through the embodiment of the invention, and the method and the device can be used as an intuitive basis for requiring the expansion of the transmission bandwidth of the PTN access ring, have general application significance, solve the problem that the transmission bandwidth cannot be effectively evaluated at the base station side and provide a basis for the positioning problem of a wireless manufacturer.
