LTE user cs domain fallback and return signaling analysis method

Abstract

The invention discloses a method for analyzing fallback and returned signalling of a LTE (Long Term Evolution) subscriber in a CS (circuit-switched) domain. The method is characterized by comprising the following steps that: signalling in a network is analyzed, tracked and correlated when a signalling monitoring system in a mobile communication network monitors voice and short message calls of the LTE subscriber in the CS domain; and the subscriber identification IMSI (International Mobile Subscriber Identity) of the subscriber and a signalling process having a complete fallback process are obtained. According to the invention, by adopting a multi-interface signalling track processing and correlated calculating method, reduction of a complete voice and short message call process of the LTE subscriber is realized; operators are convenient to perform end-to-end complete process analysis; CSFB (Circuit Switched Fallback) failure, long CSFB time delay and faults of various network nodes can be located; and thus, the method disclosed by the invention is a high-efficiency and reliable method for tracking and analyzing voice and short message calling processes of the LTE subscriber in the CS domain.
