Wherein, it should be noted that those of ordinary skill in the art can easily understand that the signaling board load of the RNC is a dynamically changing value, so the signaling board load of the RNC described in the embodiment of the present invention is the RNC's signaling board load in the sampling period Average signaling board load.

It should be noted that user habits and behaviors under the RNC are quite different. Therefore, to accurately evaluate the bearing capacity of the RNC signaling plane, sufficient sampling data is required for support. Preferably, in this embodiment of the present invention, the sampling data of 7 days*24 hours is used to evaluate the bearer capacity of the RNC signaling plane, that is, the N sampling points may specifically be sampling points with a sampling period of 7 days and a sampling period of 1 hour. In this way, there will not be too much data to be collected, and at the same time, the collected data is general, which can more accurately evaluate the bearer capacity of the RNC signaling plane.

Perform linear fitting on the signaling board load of the RNC at each of the N sampling points and the number of normalized signaling lines to obtain the signaling load ratio of the RNC, wherein the signaling load ratio of the RNC It is used to represent the number of signaling lines that the signaling board load of the RNC can carry when the load increases by 1%.

S104. Evaluate the bearer capacity of the RNC signaling plane according to the signaling load ratio of the RNC.

According to the number of RRC connection establishments, the number of RRC connection releases, the number of RAB connection establishments, the number of RAB connection releases, the number of handovers, the number of channel migrations, and the preset second parameter, combined with the first preset formula, calculate the The number of normalized signaling entries of .

Wherein, the second parameter includes: the number of RRC connection establishment signaling, the number of RRC connection release signaling, the number of RAB connection establishment signaling, the number of RAB connection release signaling, the number of handover signaling, and the channel migration signaling Number of bars. It should be noted that the number of RRC connection establishment signaling, the number of RRC connection release signaling, the number of RAB connection establishment signaling, the number of RAB connection release signaling, the number of handover signaling, and the number of channel migration signaling You can refer to the standard signaling process of the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP).

It should be noted that, in the method for evaluating the bearing capacity of the RNC signaling plane provided in the embodiment of the present invention, those of ordinary skill in the art can easily understand that when the load of the signaling board of the RNC and the number of normalized signaling lines are linearly simulated After combining the obtained T-S curve, the correlation coefficient (also known as the degree of fit) of the T-S curve should be obtained. When the correlation coefficient reaches a preset value (such as 0.9), it is considered that the T-S curve obtained by this fitting is accurate. The linear relationship between the signaling board load of the RNC and the number of normalized signaling lines can be expressed accurately, and the slope of the T-S curve can be determined as the signaling load ratio of the RNC.

Preferably, in the RNC signaling plane bearing capacity evaluation method provided in the embodiment of the present invention, according to the signaling load ratio of the RNC, the RNC signaling plane bearing capacity is evaluated, which may specifically include:

If the signaling load ratio of the RNC is greater than the first threshold, it is determined that the bearer capacity of the RNC signaling plane complies with a preset standard.

If the signaling load ratio of the RNC is not greater than the first threshold, it is determined that the bearer capacity of the RNC signaling plane does not meet the preset standard.

Wherein, the first threshold may be specifically set according to actual conditions.

Evaluate. For example, assuming that the calculated signaling load ratio of RNC1 is 452,000 and the signaling load ratio of RNC2 is 320,000, the bearing capacity of the signaling plane of RNC1 is better than that of RNC2.

Exemplarily, taking a certain RNC provided by equipment vendor A as an example, the specific process of evaluating the RNC signaling plane bearer capacity by using the RNC signaling plane bearer capacity evaluation method provided by the embodiment of the present invention is given as follows:

S1. Obtain sampling data related to the RNC.

Table 1

S2. Calculate the number of normalized signaling pieces at each sampling point.

Exemplarily, taking the sampling data of the first sampling point on June 23, 2014 in Table-1 as an example, the number of normalized signaling at this sampling point=5*593961+4*594631+4* 515320+5*515224+4*551910+4*908816=908816.

S3. Perform linear fitting on the signaling board load of the RNC at each sampling point and the number of normalized signaling lines by using the least square method to obtain a T-S curve.

That is, the load of the signaling board at each sampling point and the number of normalized signaling lines are taken as a set of data, and 7*24 sets of data are used for linear fitting. Exemplarily, it can be seen from Table-1 that the signaling board load at the first sampling point on June 23, 2014 is 23.121 (%), step S2 calculates the first sampling point on June 23, 2014 The number of normalized signaling items at the location is 908816, then (23.121, 908816) can be taken as a set of data.

The TS curve obtained by fitting is shown in FIG. 2 , and the signaling board load of the RNC and the number of normalized signaling lines satisfy: T=622028S+10 ⁶ .

S4. Calculate the correlation coefficient of the T-S curve, and if the correlation coefficient exceeds a preset value, determine the slope of the T-S curve as the signaling load ratio of the RNC.

Assuming that the preset value is 0.9, the correlation coefficient of the fitted T-S curve is 0.99, and the slope of the T-S curve is known to be 622028, then the signaling load ratio of the RNC is 622028, which means that the signaling board load of the RNC per The number of signalings that can be carried by a 1% increase is 622028 times.

S5. Evaluate the RNC signaling plane bearer capacity according to the signaling load ratio of the RNC.

At this time, the signaling plane bearing capacity of the RNC can be evaluated according to the first threshold, or the signaling load ratio of the RNC can be compared with the signaling load ratios of other RNCs, and the RNC's signaling load ratio can be compared with that of other RNCs based on other RNCs. Evaluate the carrying capacity of the signaling plane.

Exemplarily, assuming that the first threshold is 633000, comparing the signaling load ratio of the RNC with the first threshold, it can be known that the signaling load ratio of the RNC is lower than the first threshold, and the RNC signaling plane bearer capacity does not comply with Preset standard; assuming that the signaling load ratio of the RNC provided by another equipment vendor B is 679,460, that is, the signaling board load of the RNC provided by equipment vendor B can carry 622,028 signaling times when the load of the RNC board card provided by equipment vendor B increases by 1%, while that provided by equipment vendor A The signaling load ratio of the RNC is 622028, that is, the signaling board load of the RNC provided by equipment vendor A can carry 622028 signaling times when the load of the RNC signaling board increases by 1%. Therefore, compared with the RNC provided by equipment vendor B, the signaling plane bearer capacity of the RNC provided by equipment vendor A is weaker.
