Problems solved by technology
[0006] When the monitoring agency monitors the monitored user, in the uplink direction, the monitored user needs to report the monitoring information to the monitoring agency through the ISP network. Since the monitoring type is CC, the data volume of the monitoring information is huge, and the uplink of the ISP network The bandwidth is much smaller than its downlink bandwidth, which may cause network congestion, resulting in failure to monitor CC

The invention discloses a monitoring method, a device and a system and relates to the field of communication networks, thereby being capable of monitoring communication content when a monitored user is in the connecting state that a family wireless access point is led out of a Gi interface. The embodiment of the invention provides the monitoring method, which comprises the following steps: a monitored network element receives a legitimate monitoring and activating request message from a monitoring gateway, wherein the monitored network element is positioned in a packet data network; the monitored network element determines that the monitored user is in the connecting sate that the family wireless access point is led out of the Gi interface; and the called network element makes the monitoring response to the monitoring gateway, thereby instructing the monitoring gateway to re-initiate the monitoring against the monitored user at an Internet server provider ISP network. The invention isapplicable to scenes for monitoring the network elements in a communication network.
Description
technical field [0001] The invention relates to the field of communication networks, in particular to a monitoring method, device and system. Background technique [0002] Femtocell technology, also known as home wireless access technology, is a general term for a low-power wireless access point technology. A wireless access point device is included in the Femtocell system to provide wireless access functions, such as , a Femto access point (Access Point, AP), also known as a home wireless access point, wherein, in the 3rd Generation Partnership Project 3GPP network, the home wireless access point used for the long-term evolution (Long Term Evolution, LTE) network The entry point is called Home Node B (HNB), and the home wireless access point used for UMTS Territorial Radio Access Network (UTRAN) is called Home Evolved Node B (Home Evolved Node B, HeNB). The user equipment uses the licensed spectrum through the home wireless access point, and accesses the network through t...
