Abstract:
1. A method of collecting data using a Mobile Identification Number (MIN) in a Wideband Code Division Multiple Access (WCDMA) network, in which transmitted and received data related to a mobile station is collected in an Iu-PS interface link in the WCDMA network, in which an SGSN and an RNC are connected to each other via the Iu-PS interface link and the SGSN and a GGSN are connected to each other via an Gn interface link, the method comprising the steps of: (a) reassembling ATM/AAL5 data into SCCP and higher layer data in the Iu-PS interface link, and capturing the reassembled data; (b) extracting SLR or DLR data from Connection Request (CR) or Connection Confirm (CC) of the captured SCCP data, and storing reference Radio Access Network Application Part (RANAP) message data having the higher layer data in storage based on the extracted SLR or DLR data; (c) extracting a mobile IP address related to a MIN of the mobile station in the Gn interface link; and (d) registering SLR or DLR data having the mobile IP address, and, afterward, capturing and extracting transmitted and received data having the SLR or DLR data in the Iu-PS interface link.
