An illustrative embodiment disclosed herein is a non-transitory computer readable medium. The medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to identify a user database record associated with a user equipment (UE) using a mobile identity (ID), associate a Next Generation application protocol (NGAP) session with the user database record using an NGAP ID, capture a ciphered message associated with the NGAP session, decipher the ciphered message associated with the NGAP session, extract, from the deciphered message, session details associated with the UE, and store the session details in a session detail record.

5G N1/N2 interface monitoring system

An illustrative embodiment disclosed herein is a non-transitory computer readable medium. In some aspects, the non-transitory computer readable medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to capture a transaction transmitted over an N12 interface, extract, from the transaction, one of an expected response (XRES) or an authentication token (AUTN), a user identifier (ID), and a cipher key, capture a first message transmitted over an N1 interface, and determine that the first message is associated with the user ID and the cipher key extracted from the transaction.

5G NAS deciphering enhance rate of convergence mechanism

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.

Processing paging requests messages in a wireless communication system

A plurality of data packets is received from a wireless communication system. At least one of SIP signaling messages and S1-AP signaling messages associated with calls being made or attempted in the wireless communication system are analyzed for a specified time period to identify one or more dropped calls. At least one of SIP signaling error codes and S1-AP signaling cause codes associated with the identified dropped calls are analyzed to identify one or more call drop reasons. An ASI data set is generated based on the analysis of the at least one of the SIP signaling messages and the S1-AP signaling messages and based on the analysis of the at least one of the SIP signaling error codes and the S1-AP signaling cause codes.
