Claim Text:
1. A method for real-time network monitoring, comprising: monitoring, via a lightweight session tracking module of a network monitoring device, control plane data for connectivity sessions of User Equipment (UE) in a communication network, each of the connectivity sessions comprises General Packet Radio Service (GPRS) Tunneling Protocol (GTP) session, wherein the monitoring connectivity sessions comprises monitoring GTP protocol control plane message traffic between network interfaces of a plurality of network nodes in the communication network, the plurality of nodes comprises at least one of an Evolved Node B (eNB), a Mobility Management Entity (MME) node, a Serving Gateway (SGW) node, a Packet data Network Gateway (PGW) node, and a Serving General Packet Radio Service (GPRS) Support Node (SGSN); selectively identifying, via the lightweight session tracking module, at least one bearer for a corresponding connectivity session according to one or more control plane attributes; associating, via the lightweight session tracking module, each selectively identified bearer for the corresponding connectivity session with a bearer routing rule for user plane data; receiving, via a packet routing module of the network monitoring device, user plane data for connectivity sessions of UE and associating a correlation identifier with the received user plane data; and transmitting, via the packet routing module, the correlation identifier and the user plane data of the connectivity sessions according to the bearer routing rule of the lightweight session tracking module to a flow processing module for subsequent data flow analysis.
