Embodiment Construction

[0028] The present invention is based on the user identification number of the monitored target user, such as the International Mobile Subscriber Identification Number (IMSI), or a mobile digital number (MDN, Mobile Digital Number) or an electronic serial number (ESN, Electronic Serial Number), etc., by communicating with The HLR interacts to get the MSC where the target user is located, and then obtains the BSC ID where the target user is located through the interaction with the MSC, and searches the correspondence table between the BSC ID and the PDSN IP address stored locally in the monitoring system, because one BSC ID may correspond to more than one PDSN IP address, and therefore send interception requests to candidate PDSNs respectively.

[0029] Considering that during the process of monitoring, the target user accesses the network in various states and situations, the following describes the interception in the middle, the pre-monitoring, the target user switching betwe...

Abstract

The invention provides a monitoring method for group service in group domain, which includes following steps: A) monitoring system and HLR acquire the service MSC accessed by target user interactively according to the user identification number of target user, and interacts with the service MSC, gets the BSC ID of service BSC; B) searches the relation table of BSC ID reserved by the monitoring system and the PDSN IP address, and sends monitoring application to PDSN correspondent to the BSC ID respectively; C) each PSDN receives the monitoring application, and returns the monitoring application reply information to the monitoring system, the message contains the state mark of target user, the monitoring system judges if the target user has been accessed into the group domain according to the user state mark, if yes, the service PDSN connects with the monitoring system, monitors the service stream, otherwise the monitoring continues to wait until the service PDSN igniting the monitoring, the service PDSN connects with the monitoring system, and monitors the service stream.

Description

technical field [0001] The invention relates to the technical field of mobile communication security, in particular to a monitoring method for packet services. Background technique [0002] With the demand and development of mobile packet data services, there is an imminent need to provide a legal interception function. For the increasingly widely used Code Division Multiple Access (CDMA) system, it is also necessary to formulate legal monitoring interface specifications. [0003] see figure 1 As shown, in the existing CDMA system, the target user (MS) communicates through the base station controller (BSC), and the BSC communicates with the packet data service node (PDSN, Packet Data ServingNode). The C interface is between the HLR and the MSC. The A interface is the interface between the BSC and the MSC, and the A10 / A11 interface is the interface between the BSC and the PDSN. [0004] The monitoring system includes a monitoring center (LEA) and a legal interception acces...
