Description
Technical field
The present invention relates to network performance measurement field, more particularly to a kind of method for obtaining gsm system exception call drop data
And system.
Background technology
At present, (call drop is not by Radio Link Failure for base station side acquisition global system for mobile communications GSM exceptions call drop
And/or handoff failure causes) Main Means of data are that the order of Abis messages is tracked in wireless side, or pass through drive test
The signaling of (Driver Test, DT) admission test terminal MS, in conjunction with technological means such as backstage statistics, to system exception call drop
Situation is analyzed.
But there is very big defect in the abnormal call drop data capture method taken at present：
1) Abis messages order can only record the Signalling exchange of base station transceiver BTS and base station controller BSC in Abis mouths
Situation, BTS and MS can not be reacted completely in the interaction scenario eated dishes without rice or wine, such as data link layer L2 interactive information, and big portion absolutely
Gsm system exception call drop is divided can only accurately to be analyzed by L2 interactive information, position abnormal call drop reason, therefore by existing
The validity for the abnormal call drop data that abnormal call drop data capture method is got is not high.
2) exception that the currently used resource of test terminal can only be got by way of DT enrolls mobile MS signalings is fallen
Talk about data, the abnormal call drop data of all available resources in base station can not be got in time, do not utilize to the overall analysis of network and
Optimization.
