Embodiment Construction

[0042] The Web-based SIP terminal described in the embodiment of the present invention adopts SIP as a signaling protocol, can run on various system platforms, and supports media transmission of audio and video. It mainly includes four components: user interface, call control module, media processing module and SIP protocol stack, and the software architecture of Web-based SIP terminal is as follows: figure 1 shown.

[0043] The SIP terminal application inherits the Java cross-platform Applet program, can run on multiple browsers and multiple platforms, and supports video communication in addition to audio communication.

[0044] Wherein, for the user interface, the user can control the running of the program through a small application program interface embedded in the browser. The applet is embedded in the HTML webpage, and the user interface mainly consists of two parts: the interface of the applet and the HTML interface.

[0045] The user interface provides all the stand...

Abstract

The invention discloses a session initiation protocol (SIP) terminal and a session processing method. The method comprises the following steps of: extracting a key file from a corresponding catalogue after the operation of a Java media framework (JMF) installation program is finished, wherein the key file includes a jmf.jar (Java Archive) file relating to the JMF, a jmf.properties file recording local properties of a client, and a local link library file; storing the files into a web server; and downloading the files to the corresponding catalogue when loading and operating an applet in the SIP terminal to realize the installation-free property of the SIP terminal, and performing calling control based on the installation-free property of the SIP terminal. By the SIP terminal and the session processing method provided by the invention, the installation-free property and the cross-platform property of the SIP terminal can be guaranteed effectively.

Description

technical field [0001] The invention relates to the communication field, in particular to a session initiation protocol (SIP) terminal and a session processing method thereof. Background technique [0002] The SIP protocol draws lessons from the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP), which has the advantages of simple structure, scalability and scalability; in addition, it also provides good quality of service (QoS) support, so based on The multimedia interactive communication of SIP is more and more recognized and valued by people. The SIP protocol is used to control the interactive session process of device initialization, management and termination on the Internet or other networks, including voice and the entire network-related content. The SIP network adopts the client-server working mode, and the SIP network includes two types of components: SIP user agent and network server. A user agent is an end system that represents a us...
