摘要:
The present invention relates to a method of extracting WAP data using a mobile identification number, which uses a mobile identification number, which is a static factor, so that there is no need to personally inquire of a manager about an IP address assigned to a given mobile station in a temporal restriction, thus more conveniently and promptly extracting WAP data. In the WAP data extraction method of the present invention, all of the data packets passing through a WAP gateway are captured. Primary filtering is performed by determining whether each of the captured data packets uses the IP address of the given WAP gateway as an intermediate IP address, or has a port corresponding to a WAP protocol. Whether a Mobile Identification Number (MIN) is present in a header of data filtered in the primary filtering is determined. Whether the MIN is identical to a registered MIN is determined if a MIN is determined to be present. An IP address or a port number included in the header is registered, while the data packet is stored if the MIN is determined to be identical to the registered MIN. Secondary filtering is performed on the data packet having the IP address or the port number, and data filtered through the secondary filtering is stored.

Disclosed herein is a method of collecting data using a Mobile Identification Number (MIN) in a Wideband Code Division Multiple Access (WCDMA) network. The method includes the steps of (a) reassembling ATM/AAL5 data into SCCP and higher layer data in an 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 the 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.

Accordingly, the present invention relates to a monitoring system and method for a trunk gateway. In the monitoring system of the present invention, a trunk gateway is interposed between the Internet and a PSTN and is adapted to packetize a trunk line into packets and to transmit the packets to the Internet, or to perform a reverse procedure. The monitoring system includes a VoIP agent connected to the Internet and adapted to originate and terminate a VoIP call and to generate an MOS value using a voice file received from a counterpart. A circuit network agent is connected to the PSTN and adapted to originate and terminate a call and to generate a MOS value using a voice file received from a counterpart. A center server performs various types of control operations related to measurement of service quality of the trunk gateway, including establishment and termination of a call, and collects the MOS values. A manager PC sets in the center server a test scenario, required for measurement of service quality of the trunk gateway, and a threshold value, required for evaluation of the MOS values. An ISUP probe analyzes a packet on an ISUP node of the trunk gateway, extracts information about a channel of the trunk gateway to which a current call is connected, and provides the extracted channel information to the center server.
