Technical field

The present invention relates to the field of mobile communications, and specifically relates to a device performance data reporting method, a device performance statistics method, a distributed device, a total control device, and a device performance statistics system.

BACKGROUND In a mobile communication system, since the performance data of the entire network reflects the operation quality of the entire network, it is indispensable for the operator; in addition, accurate performance statistics for network optimization of a large-scale commercial network, Trouble shooting and other aspects also play an important role. Performance statistics are generally collected through periodic collection of network metadata and then aggregated into the network management system. Due to the large amount of performance data, how to perform effective and accurate data management and data reporting is a key issue in performance management. In a mobile communication system in reality, network elements are mostly distributed implementation architectures, such as a wireless network controller (RNC) that uses different CPUs to complete the collaborative process of wireless services. Due to the large amount of data in the performance statistics, in order to smooth the load that the data reports to the system, the long-term distributed long-term summary method is used to collect the performance indicators. The traditional device performance statistics system structure is shown in Figure 1. Shown. As shown in Figure 2, the long-term distributed sample long-term summary method steps are as follows:

S101: The performance statistics module on the total control device and the distributed device opens a performance data buffer area, and the number of measurement types supported by the device according to the device, the maximum number of each measurement type counter, and the maximum measurement object of the device The memory space is allocated by the number and the length of the counter under this measurement type.

S102: Define an operation code and a summary code for each counter. The operation performed when saving a counter to the performance data buffer on a distributed device is defined as an opcode, and the operation performed when the master device saves the counter to the performance data buffer is defined as a summary code. Generally, by setting the opcode and summary code, the counter can be divided into summation statistics type, mean value statistics type, and maximum value statistics type according to its processing mode. For example, the summation statistic type is to calculate the increment of the data at the end of a period relative to the start, the summation counter opcode is set to sum, and the counter summary code is set to sum; the statistic type is to obtain more than one cycle. The average of the raw data of the sample points; the average counter operation code is set to sum, the summary code is set to average; the highest value statistics The type is to obtain the maximum or minimum value of the raw data of multiple sample points in one cycle, the highest value counter operation code is set to the maximum value, and the summary code is set to the sum. In addition, according to the monitoring needs of specific equipment, the specific processing method of the counter, the operation code and the summary code can also be set to other operation modes, and some other counter-specific types are defined. S103: During the running of the system, when the data source on each distributed device needs to be counted, the data source reports the value of the counter to the performance statistics module on each distributed device, and the statistics period starts, and the performance statistics module is pre-defined. The counter operation code is used to save the value reported by the counter in the performance data buffer of the distributed device. In addition, the distributed device may also sample the data source, and the statistical period starts, and the sample value is used as the value reported by the counter. Assume that the counter is the most valued statistical type, set the highest value counter opcode to the highest value, and the summary code to the summation. The performance statistics module saves the value reported by the counter to the highest value and saves it in the performance data buffer of the distributed device. .

S104: After the statistics period ends, the performance statistics module on each distributed device reports the value of the counter to the performance statistics module on the master control device; the performance statistics module on each distributed device obtains multiple sample points in a cycle. The maximum or minimum value of the data is reported.

S105: The statistics module on the master control device operates the value of the counter reported on each distributed device according to the preset counter summary code, and saves the value of the counter in the performance data buffer area of the master control device; The code is summed, and the value reported by the most value counter is summed and saved.

S106: The total control device saves the values of all the counters in the statistical period as performance files and reports them to the network management system for presentation to the user. There are some special global maximum counters, such as user maximum/minimum counter and flow max/min counter, which are counted simultaneously on multiple distributed devices, if traditional long-term statistics are used. The method is as follows: In the long-term statistical period T seconds, the statistical result of the maximum traffic of device A is maxl; in the long-term statistical period T seconds, the statistical result of the maximum traffic of device B In the long-term statistical period T seconds, the statistical result of the current system maximum traffic is sum ( maxl , max2 ), and the distributed device reports the statistical result to the master control device. However, the actual situation is that if maxl appears in the first half of the long-term statistical period, max2 appears in the second half of the long-term statistical period, and sum (maxl, max2) is reported to the master control device as the final statistical result. incorrect. According to the traditional method of long-term statistics, the statistical period of each distributed device is relatively long, usually 15 minutes. It takes such a long time to report the value of the counter to the master control device for aggregation. Not only will the statistical result be inaccurate. The problem, and can not get the global sum of a counter in real time, can not be the user clearly understand the health of the equipment in the system.

In this embodiment, the device performance statistics system and the device performance data reporting method in the embodiment are further described in detail in conjunction with FIG. As shown in Figure 4, the specific process of reporting device performance data includes the following steps:

S201: each distributed device directly saves the value of the global maximum value counter obtained from the data source in the first performance data buffer, or searches for the value of the global maximum value counter according to the predefined global maximum value counter operation code. The value is saved in the first performance data buffer;

S207: The master control device saves the values of all the counters in the statistical period as performance files and reports them to the network management system for presentation to the user.

The above steps S205 to S206 are the same as the prior art, and are not described herein again. In an application example, the device performance statistics system structure is as shown in FIG. 5, on the distributed device: the counters that need to be counted on the distributed device 1 and the distributed device n include: a current value counter A, a maximum value counter B, a minimum counter C, wherein the values of the counters A, B, and C are stored in a performance data buffer on each distributed device. A preferred storage method is to store the value of the global maximum counter in a continuous buffer. In this way, it is convenient to address the most value counter, as long as the start position and the end position are found. On the master control device: The performance statistics module on the master control device opens up the performance data buffer area, and also sets the summary buffer area and the comparison update buffer area; wherein the summary buffer area is used to save the distributed device 1 and the distributed device. The summary value of the value reported by the maximum value counter of n; the comparison update buffer is used to save the maximum value of the summary value, that is, the summary value of the last short-time sampling period and the summary value of the sampling period are larger or smaller The value; the performance data cache holds the final result that needs to be presented to the user. On the distributed device n, the performance data buffer is named DataBuffer—n, then the buffers of the current counter A, the maximum counter B, and the minimum counter C are DataBuffer—n[a], DataBuffer—n[b], and DataBuffer— n[c]; On the master control device, the summary buffer is named H, then the summary buffer of maximum counter B is H(b), and the summary buffer of minimum counter C is H(c), compare The update buffer is named G, then the comparison update buffer of the maximum counter B is G(b), and the comparison update buffer of the minimum counter C is G(c); below, the device performance statistics system in FIG. 5 above. For example, the present embodiment will be described with reference to FIG. 6 . The method for reporting and counting device performance data is further described in detail below. As shown in FIG. 6, the method includes the following steps:

S301: Set a short-time reporting timer on each distributed device (1~n), set t seconds to a short-time reporting period (for example, 6 seconds); set a long-term statistical period timer, set T minutes as statistics Cycle (for example, 15 minutes in the prior art);

S302: The timer is started, and the performance statistics module on each distributed device starts to sample the data source. Taking the distributed device n as an example, the distributed device n saves the current sample value X in the buffer area of the current counter A. DataBuffer—n[a];

S303: The value DataBuffer_n[a]=x in the buffer area of the current counter A is stored as a sample value in the buffer area DataBuffem[b] of the maximum value counter B, and the value of DataBuffem[a]=x is taken as The sample value is stored in the buffer area DataBuffem[c] of the minimum counter C; that is, the current sample value is placed in the performance data buffer corresponding to the highest value counter on the distributed device n, in order not to change the traditional master control The performance data buffer partitioned by the performance statistics module on the device and the distributed device, and the value of the current counter on the distributed device is also saved in the buffer of the highest value counter respectively, because, correspondingly, the total control device also The buffer area of the corresponding maximum value counter is divided. When receiving the value reported by the distributed device, the master control device can save according to the buffer area of the highest value counter. Of course, it is also possible to re-allocate the memory space for the performance data cache. For example, the current buffer area and the counter short-time buffer area are allocated on the distributed device, and correspondingly, the current buffer area and the counter are also allocated for a short time. The buffer area and the comparison area are saved in the corresponding buffer area allocated by the distributed control device.

S304: After t seconds, the performance statistics module on the distributed device n sends all global maximum value counter values to the master control device; that is, the buffer area DataBuffem[b] and the minimum value counter C of the maximum value counter B are The values in the buffer area DataBuffem[c] are all reported; if the amount of data is relatively large, it can be sent in multiple message packets.

S305: The performance statistics module on the master control device opens a summary buffer area, and summarizes the sample values of the highest value counters reported by each distributed device; The performance statistics module calculates the value of the most value counter reported by each distributed device ( l~n ) and the value saved in the local summary buffer (summary code is "summation"): summary buffer H(b) = DataBuffer— l [b]+ DataBuffer— 2[b] + ... + DataBuffer— n[b]; Summary buffer H(c) = DataBuffer— l [c]+ DataBuffer— 2 [c] + .. . +

DataBuffer— n[c];

S306: The performance statistics module on the master control device compares the value in the summary buffer with the value in the comparison update buffer according to the highest value counter summary comparison code, and searches for the maximum value and stores it in the comparison update buffer area; The summary comparison code of the value counter B is "maximum value", and the summary comparison code of the minimum value counter C is "minimum value". In addition, in actual implementation, the performance statistics module receives the value of the highest value counter and summarizes it. After that, there is a delay. In this embodiment, assuming that the delay is a delay of t/2 seconds (0.3 seconds), step S306 specifically includes the following steps:

1) If it is the first short time >3⁄4 period t in the data statistics period T, the time in the summary buffer area is directly used as the comparison update buffer area at the time point when the reporting period is extended by t/2 in t seconds. The value is saved: Compare update buffer G(b) = H(b); Compare update buffer G(c) = H(c);

Starting from the second short-term reporting period t, the time period in which the reporting period is extended by t/2 in t seconds is short, and the value in the summary buffer area needs to be compared with the value in the comparison buffer area, which is the largest between the two. The minimum value is saved to the compare update buffer: Compare update buffer G, (b) = Max(H(b), G(b)); Compare update buffer G, (c) = Min(H(c), G (c));

2) The value in the summary buffer is cleared; S307: The performance statistics module on each distributed device determines whether the long-term statistical period timer expires, if not, proceeds to step S302, otherwise proceeds to step S308; S308: When the long-term statistical period T is up, the performance statistics module on each distributed device reports all the maximum value counter values to the master control device; at the same time, the values of the other non-global maximum value counters are also reported to the master control device; In actual implementation, there is a case where t cannot be divisible. Although the short-term reporting period t has not yet expired, since the long-term statistical period T has expired, it is necessary to buffer the data area DataBuffem that has been buffered in the maximum value counter B. b] and the value of the minimum value counter C in the buffer DataBuffem[c] are all reported.

S309: The performance statistics module on the master control device saves the sample values of the most value counters reported by each distributed device to the summary buffer area; and, according to the summary codes of other non-global maximum value counters defined in advance, each distribution The values of other non-global maximum counters reported by the device are calculated, and the values of other non-global maximum counters are saved in the performance data buffer of the master device; similar to S305, except that this is a long-term statistical period T to after All remaining maximum value counter values reported by each distributed device last time.

S310: The performance statistics module on the master control device compares the value in the summary buffer with the value in the comparison update buffer according to the highest value counter summary comparison code, and searches for the highest value and stores it in the comparison update buffer; similar to S306 However, this is the value of all remaining maximum value counters reported by each distributed device last time after the long-term statistical period T.

S311: saving the value in the comparison update buffer area as the value of the most value counter in the long-term statistical period T to the performance data buffer area on the master control device;

S312: Save the values of all the counters (including the global maximum value counter and other non-global maximum value counters) in the performance data buffer area of the total control device in the long-term statistical period T as performance files and report them to the network management system for presentation to the user;

S313: Clear the value of the performance data buffer area on the distributed device, the summary buffer area on the master control device, the comparison update buffer area, and the performance data buffer area, and wait for the data reporting process of the next period.
