Problems solved by technology

[0004] Since the application of SIP is based on IP network, SIP has the advantages of IP network, but also brings security risks in IP network to voice communication network, especially PSTN network.
Nowadays, there have been many studies on the security problems of SIP, but the existing research focuses on the security risks caused by protocol loopholes, attack modes and their implementation, and defense algorithms, and no general experimental platform has been given.
Existing SIP call simulation software, such as SIPp, cannot accurately simulate the calling behavior of multiple users

Abstract

The invention discloses a behavior programmable session initial protocol (SIP) calling simulation method. The method comprises the following steps of: describing simulated user calling behaviors through six modulation parameters such as a calling uniform resource identifier (URI), a called URI, call setup time, ringing time, conversation time and an on-hook identifier, forming calling scripts andtransmitting the calling scripts to a client SIP functional module; interacting the client SIP functional module with a server SIP functional module according to the six modulation parameters of the simulated user calling behaviors; acquiring an SIP signalling corresponding to each simulated user calling behavior from a communication link through a packet capturing program; and transmitting the SIP signalling to a tested object so as to perform simulation and experiments. The client SIP functional module can read the calling scripts of a plurality of user calling behaviors at the same time for processing, so that the plurality of user calling behaviors can be simulated precisely so as to acquire accurate, concurrent and completely controlled SIP signalling streams.

Description

Technical field [0001] The present invention belongs to the technical field of voice communication, and more specifically, relates to a SIP (Session Initial Protocol) call simulation method with programmable behavior, by which accurate simulation of multiple user call behaviors can be realized . Background technique [0002] Session Initial Protocol (SIP) is an important protocol in the Next Generation Network (Next Generation Network). It is formulated by the Internet Engineering Task Force (IETF) and is a flexible and universal Tool. SIP itself is not a vertically integrated communication system, but needs to cooperate with other protocols, such as Real-time Transport Protocol (RTP) and Session Description Protocol (SDP) to form a complete The multimedia communication system provides services to users. Since it has nothing to do with the underlying transmission protocol and session type, SIP can provide signaling functions for different services. The SIP protocol is used to cr...
