The invention relates to the field of communication networks, and discloses a method for backfilling a user identity to SRVCC/eSRVCC A interface records. The method includes the following steps: stepa, decoding and synthesizing Sv interface messages, and extracting corresponding parameters according to different information; step b, according to key switching parameters, establishing a node for an A interface to perform associated look-up, and writing user identity information in the node; step c, decoding and synthesizing A interface messages, and extracting the corresponding parameters according to different information; and step d, when a switching completion message is received, searching the node according to the key switching parameters, finding the user identity information in thenode, and extracting the user identity information to put into the current A interface record. According to the scheme of the invention, an Sv interface and an A interface are subjected to associationprocessing through the key switching parameters, the user identity of the Sv interface is backfilled to the A interface switching record, and thus the user-level analysis of the A interface switchingrecord can be implemented.

The invention relates to the technical field of network communication, in particular to a method and device for judging a VoLTE call interworking network scenario. The method comprises the following steps: collecting interface data related to a user call scenario in a VoLTE network, and generating a single-interface telephone bill through the decoding and analysis of the interface data; judging whether the call ticket is a calling-side call ticket or a called-side call ticket according to network element equipment related to the interface; if the call ticket is a calling-side call ticket, thecalling-side user is a VoLTE voice user, the network type of the called-side user is continuously judged according to the call ticket information, and a call scene is determined; If the call ticket isa called side call ticket, the called side user is a VoLTE voice user, the network type of the calling side user is continuously judged according to the call ticket information, and a call scene is determined. According to the invention, the call ticket is obtained based on single interface data analysis, and the network types of the calling side user and the called side user can be judged by analyzing the information in the call ticket, so that the network call scene can be accurately judged.
