Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0013] The core idea of ​​the present invention is: the mechanism for detecting the encoding rate before establishing the media stream is faster and more accurate than the previous method. The quality of the media stream is greatly improved when the two parties communicate.

[0014] The communication method of the IP phone terminal in the embodiment of the present invention includes the following steps, the flow chart of which is as follows: figure 1 Shown:

[0015] Step 11, the first IP telephone terminal sends a call request message carrying its own code rate detection port number and its own supported code rate to the second IP telephone terminal;

[0016] Wherein, the call request message may be an Invite message, and the own code...

Abstract

The invention discloses an IP telephone terminal communication method. The method comprises the steps that: a first IP telephone terminal sends a call request message carrying the code rate detection port number and the supported code rate itself to a second IP telephone terminal; after receiving the call request message, the second IP telephone terminal carries the code rate detection port number and the supported code rate itself, and sends a temporary call request response message to the first IP telephone terminal; according to the code rates supported by opposite sides, the first IP telephone terminal and the second IP telephone terminal respectively send code streams to the code rate detection ports at opposite sides; the practical supportable code rates at the opposite sides are detected; furthermore, the practical supportable code rates at the opposite sides are set to local code rates; and thus, the first IP telephone terminal and the second IP telephone terminal respectively send coding frames through respective local code rates. By means of the IP telephone terminal communication method disclosed by the invention, the high-quality media stream can be obtained.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an IP telephone terminal communication method. Background technique [0002] Against the background of the increasing popularity of Internet applications and increasing access bandwidth, various Internet-based real-time communication methods emerge in endlessly. Among these methods, the one most closely integrated with the call center is IP telephony. [0003] IP phones use the SIP protocol to transmit signaling and the RTP protocol to transmit media streams. [0004] In the prior art, after the sender and receiver of the IP phone terminal complete the SIP signaling interaction, the two parties start to transmit the media stream, and send the media stream at a fixed bit rate. If the packet loss rate is large, the manual method is used. Bit rate changes. The quality of the media stream obtained in this way is not high. Contents of the invention [0005] The purpose...
