Embodiment 1

[0050] The above-mentioned technical solution of the present invention will be illustrated below by taking the realization process of the radio resource control protocol (Radio Resource Control, RRC for short) call drop rate under the cell object as an example. Assume that the sampling MOD period is 30S. The reporting cycle between the OMC and the front desk is 15 minutes. The specific implementation steps are as follows:

[0051] In step 1, five users UE1 to UE5 successfully attach from 11:00 to 11:15 on a certain day.

[0052] Among them, UE1 attaches successfully between 11:00 and 11:30 seconds, and the control plane reports an event of adding 1 to the platform performance module. The sampling value of the platform performance module is 1 at this sampling granularity. When the sampling timer expires, the sampling value 1 is written into the current user number counter, and the counter value is 1.

[0053] If there is no user access between 11:30 and 11:10, the sampling ...

Embodiment 2

[0066] The following is an example of the implementation process of the Evolved Universal Terrestrial Radio Access Network Radio Access Bear (ERAB) call drop rate under the cell object, and the technology of the embodiment of the present invention The scheme is described in detail, assuming that the sampling MOD period is 30S, and the reporting period between OMC and the front desk is 15 minutes, the specific implementation steps are as follows:

[0067] In step 1, five users UE1 to UE5 attach successfully from 11:00 to 11:15 on a certain day, and each user establishes a default bearer.

[0068] Among them, UE1 attaches successfully between 11:00 and 11:30 seconds, and the control plane reports the ERAB number plus 1 event to the platform performance module. The sampling value of the platform performance module is 1 at this sampling granularity. When the sampling timer expires, the sampling value 1 is written into the current ERAB number counter, and the counter value is 1. ...

Abstract

Disclosed are a method, an apparatus and a system for determining a call drop rate. The method comprises: a foreground of a base station recording the number of abnormally released users and the number of successfully established users in a sampling period through summation accumulation, and calculating the number of current users being online in real time in the sampling period; after the sampling period expires, the foreground of the base station writing the number of abnormally released users and the number of successfully established users in the sampling period into an abnormally-released user counter and a successfully-established user counter respectively through the summation accumulation, and writing the number of current users in the sampling period into a current user counter; and after a reporting period expires, the foreground of the base station synchronizing data on the abnormally-released user counter, the successfully-established user counter and the current user counter to a network manager, so that the network manager determines the call drop rate in the reporting period according to the number of abnormally released users and the number of successfully established users in the reporting period and the number of current users in a previous reporting period. Therefore, accuracy of the call drop rate can be ensured.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for determining a call drop rate. Background technique [0002] In the prior art, the call drop rate is an important index for measuring system performance of a mobile communication network. As a fourth-generation Long Term Evolution (LTE) system for mobile network evolution, the call drop rate index is more important. [0003] At present, the definition of the call drop rate index includes two calculation methods: method one, divide the number of users released abnormally by the total number of released users to determine the drop rate; method two, divide the number of users released abnormally by the number of successfully established users The number determines the drop rate. In the LTE system, the call drop rate index is mainly determined according to the second method. [0004] In method two, the numerator (the number of users released abnormally) a...
