Abstract: A system and method for monitoring one or more Mobility Management Entities (MMEs) with a plurality of scalable Virtual Machines (VM)/probes arranged in a cluster format. A ciphered packet is received from a MME at a smart cluster device/probe whereby data is aggregated from the individual clustered VMs/probes for distribution to a monitoring device. The smart cluster device/probe is preferably configured to decipher the ciphered packet received from the MME and extract metadata from the deciphered packet to identify subscriber information for the received packet. The deciphered packet is then distributed to one of the plurality of clustered probes to balance the load amongst the plurality of clustered probes. The balancing of loads is based upon prescribed load balancing criteria such that each packet received for an identified subscriber is sent to a same probe such that load balancing is performed on a per subscriber basis and/or with other state-based criteria.

Abstract: A system having a network monitor communicating with U and C probes monitoring SGW-U and SGW-Cs. The U probes buffer captured user plane packets from which they determine new sessions and send new session data to the network monitor, the new session data including an IP address pair of the corresponding U probe and SGW-U. The C probes inspect captured control plane packets, determine control plane packets having a same IP address as an SGW-U in the new session data, and send associated control data to a particular U probe having the IP address paired with the IP address of the SGW-U, wherein the particular U probe correlates the control data with buffered user plane packets and generates associated monitoring data.

Abstract: A system and method for monitoring one or more Mobility Management Entities (MMEs) with a plurality of scalable network probe devices arranged in a cluster format. A ciphered packet is received from one or more MMEs at a packet switching device. The packet switching device in turn sends all the ciphered packets to each of the plurality of clustered probes. Each of the network probes then in turn deciphers the packets received from the MME and extracts metadata from the deciphered packet to identify subscriber session information contained in the received packet. Each of the network probes then selectively retains deciphered packet information relating to a subscriber session and/or other prescribed criteria designated for that particular network probe and discards the remaining deciphered packet or portions of the packet so as to balance the load amongst the plurality of probes based upon prescribed load balancing criteria.

Abstract: A network node device in a communication system in which a data packet stream is received in the network monitoring node device having a Paging Message packet that is sent from a network node device. The identity of a User Equipment (UE) associated with the received Paging Message packet is then determined. A determination is then made if Paging Message information associated with the determined UE is stored in memory associated with the network monitoring device, whereupon the received Paging Message packet is filtered from the received data packet stream in the event previous Paging Message information was determined to be associated with the determined UE device in the memory. Additionally, Paging Message information is stored in the memory in the event there are no Paging Message packets stored in the memory associated with the determined UE device.
