Problems solved by technology

[0004] 1) The Abis interface signaling can only record the signaling interaction between the base transceiver station BTS and the base station controller BSC at the Abis interface, and cannot fully reflect the interaction between the BTS and the MS on the air interface, such as the interaction information of the data link layer L2 , and the vast majority of abnormal call drops in the GSM system can only accurately analyze and locate the cause of abnormal call drops through L2 interactive information, so the effectiveness of the abnormal call drop data obtained through the existing abnormal call drop data acquisition methods is not high
[0005] 2) The method of recording mobile MS signaling through DT can only obtain the abnormal call drop data of the resources currently used by the test terminal, but cannot obtain the abnormal call drop data of all available resources of the base station in time, and does not use the analysis and optimization of the network as a whole

Abstract

The present invention provides a method and system for obtaining abnormal call drop data in the GSM system, wherein the method includes recording the interaction information between the base station and the terminal in the data link layer of each call time slot through the carrier frequency of the base station; judging the carrier frequency of the base station Whether there is abnormal call drop information on the call time slot, and if there is abnormal call drop information, report the interaction information of the data link layer of the time slot recorded by the carrier frequency. The invention realizes accurate and effective acquisition of abnormal call drop data of the GSM system.

Description

technical field [0001] The invention relates to the field of network performance measurement, in particular to a method and system for acquiring abnormal call drop data of a GSM system. Background technique [0002] At present, the main means for the base station to obtain data on GSM abnormal call drop (the call drop is not caused by wireless link failure and / or handover failure) is to track Abis port signaling on the wireless side, or through drive testing (Driver Test, DT) records the signaling of the test terminal MS, and then analyzes the abnormal call drop of the system in combination with background statistics and other technical means. [0003] However, there are great defects in the current abnormal call drop data acquisition method: [0004] 1) The Abis interface signaling can only record the signaling interaction between the base transceiver station BTS and the base station controller BSC at the Abis interface, and cannot fully reflect the interaction between the...
