| Abstract: |
| Aiming at the theft problem of CDMA2000 EVDO mobile network，and combi
ning with the generating mechanism of the call detail record in CDMA wireless br
oadband network in China, the content of AAA（A
uthentication,Authorization,Accounting） call detail record is analysed and
deconstructed, an original billing communication detail records analys
is model based on data mining technology is put forward to search the connectio
n between the call detail record and the theft behavior. The screening of suspic
ious records is realized finally by writing analysis scripts. Meanwhile，the val
idity of the system model is validated by analysing the real data from Guangdong
Telecom. Test results show that the analysis model is able to complete the anal
ysis of the original billing communication detail records and find out the abnor
mal communication detail records. |
