The invention discloses a method for realizing business throughput statistics, and the main design idea is: dividing the service into at least one class; receiving the data stream from the radio link control (RLC) sublayer, and calculating each of the data streams The total amount of data payload of the service type and the total time of data transmission; Then, the service throughput rate of each type of service is obtained according to the total amount of data payload of each type of service and the total transmission time of the data stream. A statistical point may be set in a medium access control (MAC) sublayer below the RLC sublayer, and the data stream is received by the statistical point from the RLC sublayer, and the total data payload of each service type in the data stream is calculated. The amount and total time of data transmission.

As is well known, the MAC sublayer mainly completes the mapping of the transport channel to the logical channel, and whether it is signaling, CS service data, or PS service data, the upper and lower layers must be mapped through the MAC sublayer. Therefore, the present invention sets a statistical point at the MAC sublayer, which can accurately calculate the amount of uplink/downlink data currently transmitted through the MAC sublayer and the transmission time by using the mapping function existing in the MAC sublayer.

According to the background art, services are usually divided into user plane services and signaling, and user plane services are further divided into PS services and CS services. Therefore, data transmitted at the MAC sublayer can be classified into user plane data and signaling according to functions. Data, and user plane data can be divided into PS service data and CS service data. According to the statistical needs, only the throughput rate of the user plane service can be counted, and the service can be divided into two types, namely, the PS service and the CS service, and the throughput of the signaling can also be counted.

In addition, the PS service and the CS service are internally subdivided into multiple services, such as: CS Conversation, CS Streaming, PS Conversation, PS Streaming, PS, and PS. background (Background) services, etc., and each PS or the CS service will be different according to a further classification rate requirements, such as: the rate of ²⁸ ⁸ Kbps Conversation CS service and a CS rate of 57.6 Kbps Conversation business.

In addition, when calculating the traffic throughput rate, the signaling is usually divided into uplink signaling and downlink signaling, and various PS services or CS services are classified into PS/CS uplink (UpLink) service and PS/CS downlink (DownLink). ) Services, such as: PS Streaming UpLink service, PS Streaming DownLink service, etc., various combinations are more, no longer - enumerated. Each type of PS/CS uplink or downlink service is further subdivided at a specified service rate, such as: PS Streaming DownLink service at a rate of 144 Kbps, PS Streaming UpLink service at a rate of 144 Kbps, and so on. For the case where the specific PS service and the CS service are classified by rate, refer to Table 1. In Table 1, the UpLink cartridge is called UL, and the DownLink is simply referred to as DL:

The above table is only a preferred example of classifying PS and CS services by rate, and the present invention does not limit the specific classification method of services.

1 is a schematic diagram of a processing flow of a preferred embodiment of a method according to the present invention. As shown in FIG. 1, the specific processing includes:

Step 101: Set statistics points in the MAC sub-layer in advance, and classify services. The specific classification method is as described above, and is not described here.

Step 102: The statistical point receives a data stream of each type of service from the RLC sublayer. Step 103: The statistics point collects the total data payload of each type of service and the total transmission time of the data stream according to the received data stream. Here, a statistical period may be preset, in which the statistical point receives a segment of the data stream from the RLC sublayer and counts the segment data stream.

According to the protocol, the MAC sublayer can determine the service type to which the currently received data stream belongs by using the service rate, the PS service/CS service/signaling information carried in the cell received by itself, and thus can be used for each class. The service is to count the total amount of data payload and the total transmission time of the data stream.

Among them, the data stream of the RLC sublayer has three transmission modes: acknowledge mode (AM), unacknowledged mode (UM), and transparent mode (TM). For CS services with high latency requirements, data is generally transmitted in TM mode. For PS services with lower latency requirements, AM mode is usually used to transmit data, while signaling is usually transmitted in AM or UM mode. Different transmission modes will correspond to different RLC subheaders. When the statistics point is in the total amount of statistical data payload, the RLC subheader of the transmission mode needs to be removed according to the transmission mode of each data packet in the current service type data stream to be counted. The data payload of each data packet is obtained, and the data payload of each data packet is accumulated to obtain the total data payload of the data stream of the current service type.

In addition, there are several ways to count the total transmission time of the data stream: 1. If presupposed If the data stream is continuously transmitted in the statistical period, the statistical period can be directly used as the total transmission time of the data stream. Second, a timer is set at the statistics point, and the following steps are performed for each type of service: When starting to receive the data stream, the timing starts. If the data stream transmission is interrupted in the same statistical period, the timer is suspended. When the data stream resumes transmission in the same statistical period, the timer is restarted and the timer is stopped until the statistical period is reached. The timing result of the counter is the statistics. The total transmission time of the data stream of the current service type in the period; 3. In the statistical period, for each type of service, the total number of transmission time intervals (TTIs) of the service data transmitted by each transmission channel is accumulated, and one TTI represents a radio frame. The duration, that is, 10 ms, so the total number of TTIs of each type of service multiplied by 10 ms is the total transmission duration of the current service type radio frame, that is, the total transmission time of the current service type data stream. Here, in a specific implementation, any one of the above three methods may be selected according to the characteristics of the system to count the total transmission time of the data stream.

Step 104: The statistics point is used for each type of service, and the total data payload counted in step 103 is divided by the total transmission time of the data stream to calculate the service throughput rate of the service. Here, in order to facilitate the operator to view the service throughput of various services, the statistical point can further transmit the calculated service throughput of various services to the performance unit of the operation and maintenance system.

For the step 104, the present invention also provides another implementation method, that is, the statistics point directly reports the data payload total amount and the total data transmission time of the data collected in the step 103 to the performance unit, and the performance unit is based on the performance unit. The total amount of data payload received and the total transmission time of the data stream are calculated to obtain the service throughput rate of each type of service. '

The method of the present invention is typically implemented on the UTRAN side of the UMTS, and the statistical points are typically placed at the MAC sublayer on the RNC side.

The total transmission time is sent to the throughput calculation unit, and the throughput calculation unit is configured to use the total amount of data payloads of each type of service received. The total transmission time of the data stream is calculated to obtain the service throughput rate of various services. The system may further include a statistical point disposed in the MAC sublayer, the parameter statistics unit may be disposed in the statistical point, and the throughput rate calculation unit may be set in the statistical point or may be disposed outside the statistical point.

In addition, the system of the present invention may further comprise: a performance unit disposed in the operation and maintenance system for displaying the service throughput rate of each type of service to the operator. Wherein, when the throughput calculation unit is set in the statistical point, the throughput calculation unit is further configured to send the service throughput rate of each type of service to the performance unit; when the throughput calculation unit is set outside the statistical point, The throughput calculation unit may also be disposed in the performance unit, and the performance unit may directly display the respective service throughput rates calculated by the throughput calculation unit.
