Long-term evolution voice signaling acquisition and service correlation method and apparatus

Abstract

The invention discloses a VOLTE (Voice Over LTE) signaling acquisition and service correlation method and apparatus. The VOLTE signaling acquisition and service correlation method includes the steps: setting acquisition interfaces which at least include a plurality of interfaces of an IMS (IP Multimedia Subsystem) domain, a plurality of interfaces of an EPC (Evolved Packet Core) domain and a plurality of interfaces of a CS (Circuit Switch) domain; setting acquisition positions which at least include an SBC (Session Border Controller), a DRA (Diameter Routing Agent), an MME (Mobile Management Entity), a eMSC (evolved Mobile Switching Center), an MSC (Mobile Switching Center), I/S-CSCF (Interrogating/Serving Call Session Control Function) and MGCF (Media Gateway Control Function); according to the networking mode, selecting a corresponding mirror image method or a light splitting acquisition method or a TAP (Testing Access Point) acquisition method to perform VOLTE signaling acquisition on the corresponding acquisition interface at the acquisition position; and based on the VOLTE signaling, performing VOLTE registration service association and VOLTE call service association.

Description

technical field [0001] The present invention relates to communication signaling collection and service association technology, in particular to a method and device for VOLTE signaling collection and service association applicable to Long Term Evolution (LTE, Long Term Evolution) mobile communication network. Background technique [0002] The collection of long-term evolution-based voice (VOLTE, Voice Over LTE) signaling is generally only collected for the Session Initial Protocol (SIP, Session Initial Protocol) message in the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) domain. Limited business associations within the domain. Since the VOLTE service involves the Evolved Packet Core (EPC, Evolved Packet Core) domain, the IMS domain, and the Circuit Switch (CS, Circuit Switch) domain, it can be seen that the current collection of VOLTE signaling does not have the capability of end-to-end analysis of VOLTE signaling. conditions, it is difficult to realize the correla...
