SYSTEM AND METHOD FOR GTP SESSION PERSISTENCE AND RECOVERY

摘要

A method for monitoring GPRS Tunneling Protocol (GTP) sessions in a mobile communication network having a monitoring module. The method includes the steps of monitoring, by the monitoring module, a plurality of subscriber GTP sessions, and storing recovery parameters related to the subscriber GTP sessions and subscribers associated therewith in records in a database in the monitoring module, wherein the recovery parameters are associated with initial session data for each subscriber GTP session. Upon an outage in monitoring, the method restarts the monitoring module to determine restart parameters associated with existing subscriber GTP sessions and subscribers associated therewith in the records in the database wherein the restart parameters are associated with subsequent session data for each subscriber GTP session. Before attempting to process any packets, the method associates the subsequent session data with the initial session data based upon comparing the recovery parameters with the restart parameters.

1. A method for monitoring General Packet Radio Service (GPRS) Tunneling Protocol (GTP) sessions in a mobile communication network having a monitoring module, the method comprising the steps of:
monitoring, by the monitoring module, a plurality of subscriber GTP sessions; storing recovery parameters related to the subscriber GTP sessions and subscribers associated therewith in records in a database in the monitoring module, wherein the recovery parameters are associated with initial session data for each subscriber GTP session; upon an outage in monitoring, restarting the monitoring module to determine restart parameters associated with existing subscriber GTP sessions and subscribers associated therewith in the records in the database wherein the restart parameters are associated with subsequent session data for each subscriber GTP session; and before attempting to process any packets, associating the subsequent session data with the initial session data based upon comparing the recovery parameters with the restart parameters.
