Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for testing a terminal call based on a session initiation protocol SIP.
Background
SIP (Session Initiation Protocol) is a multimedia communication Protocol established by IETF (internet engineering Task Force), a text-based application-layer control Protocol for creating, modifying and releasing sessions of one or more participants. The method is widely applied to CS (circuit switched), NGN (Next Generation Network) and IMS (IP multimedia Subsystem) networks, and can support and apply to multimedia services such as voice, video, data, and the like, and also can apply to feature services such as Presence, Instant Message, and the like.
SIP terminals are end users in SIP systems for initiating call requests and responding to call requests. In order to detect the communication status between the SIP terminals, a call test may be performed on the SIP terminals to test the performance of the call voice, such as howling, echo suppression, noise reduction, voice continuity, and H264 screen. Currently, when a call test is performed on a SIP terminal, IMS equipment is generally used. Firstly, a whole set of IMS equipment is used for building a test system, a PC is selected as a local test host, a mobile terminal, an x-lite terminal and a dispatching desk are installed on the test PC, and a Yeelink hard terminal, an azimuth hard terminal and a Kaidapp instrument are connected to a HUB repeater through network cables. After the test system is built, different SIP terminals can be connected with the IMS equipment through WIFI, and then call test is carried out.
AS shown in fig. 1, the network element structure diagram for performing a call test by using an IMS device includes a test terminal, a terminal to be tested, a proxy call session control entity P-CSCF, an inquiry call session control entity I-CSCF, a serving call session control entity S-CSCF, a home subscription data service HSS, an application server AS, and a media forwarding device MP. After the registration process is completed, the test terminal sends call request information SIP INVITE to the P-CSCF, the P-CSCF forwards the call request information SIP INVITE to the S-CSCF, and the S-CSCF carries out addressing according to the information in the call request information SIP INVITE, then sends the information to the P-CSCF corresponding to the tested terminal and forwards the information to the tested terminal; the tested terminal replies the agreement message 200OK and returns the agreement message to the testing terminal through the P-CSCF and the S-CSCF, and the testing terminal replies a confirmation ACK message after receiving the agreement message 200OK and sequentially forwards the confirmation ACK message to the tested terminal, thereby completing the call testing process. The network topology for the call test is shown in fig. 2.
Therefore, the cost of the IMS equipment is high, the steps for building the test system are complex, and in the test process, when the signaling and the media packet are forwarded layer by layer through the IMS equipment, the problems of packet loss, signaling delay and the like often occur through more routes, and the performance of the SIP terminal cannot be truly reflected. Once network packet loss occurs, packet loss conditions among network elements need to be checked, and inconvenience is caused to call test of the SIP terminal.
