Problems solved by technology

[0006] (1) To use the SIP protocol stack for multiple applications to communicate, multiple user agent classes must be implemented, and at the same time occupy the same amount of system resources and network resources, resulting in a waste of resources. It is not suitable for systems with relatively tight resources.
[0007] (2) This architecture mainly uses the concept of polymorphism in object-oriented programming, which limits this implementation to be implemented in object-oriented languages ​​such as C++ and JAVA

Embodiment Construction

[0052] The key of the present invention is: the application component identification correspondence table is established in advance at the first and second communication terminals, the application component identification correspondence table contains a plurality of records containing application component information and application component identification, through the header in the SIP request message The domain User-Agent is used to transmit the application component ID, and the communication end that receives the request message searches the corresponding table of the application component ID to obtain the application component information, and then calls the corresponding application component to process the request message. In the present invention, the SIP protocol stack manages the corresponding table of application component identifiers to ensure that the application component identifiers do not conflict, realize that different types of application components share the...

Abstract

The method comprises: the first communicational terminal evaluates the header field of a request message as a IP of a application module, and sends the request message to a second communicational terminal; the second communicational terminal receives the request message, and gets the application module ID, and the calls the application module corresponding to the application module ID; the application module processes the request message. The invention also reveals a communication terminal and a system thereof. The solution provided by the invention implements that different type of application modules share one SIP protocol stack.

Description

technical field [0001] The invention relates to a sharing technology in the field of communication technology, in particular to a SIP message communication method, communication terminal and system. Background technique [0002] SIP (session initiation protocol, session initiation protocol) is an application-layer control protocol for multimedia communication on an IP network proposed by IETF and supported by research. It is used to create, modify and terminate sessions attended by one or more participants. [0003] At present, SIP has received widespread attention because of its simplicity, flexibility and easy-to-extend features. SIP is not only the core protocol in VoIP (Voice over IP, IP telephony) systems, but also more and more SIP extension protocols emerge in endlessly, such as RFC3265, RFC3903, RFC3428, etc. respectively define SUBSCRIBE, NOTIFY, PUBLISH, MESSAGE and other SIP request message types and responses. At the same time, there are more and more different ...
