Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the implementation of technical solution of the present invention is described in further detail:

[0035] Please refer to FIG. 1 , which is a network diagram for realizing the file transfer service of the present invention. In this figure, terminals 1, 2, 3, an access gateway, and an AS (Applicant Server, application server) are included.

[0036] Terminals 1, 2, and 3 can be devices such as PCs, PDAs, or mobile phones;

[0037] An access gateway, such as a broadband gateway (BROAD BAND GATEWAY, BGW), is used to forward signaling and media between the terminal and the AS, and this media refers to the content of the MSRP file in the present invention;

[0038] The application server AS is a server deployed on the Internet, which is used to implement SIP signaling negotiation and MSRP file content forwarding;

[0039] The SIP protocol stack module is integrated on the terminals 1, 2, 3 and the application server AS, and i...

Abstract

The invention discloses a SIP- and MSRP- based file transmitting system and method. And the method comprises the steps of: setting first terminal, second terminal and application server and setting SIP protocol stack module and MSRP protocol stack module on the first terminal, second terminal and application server, respectively; 2. completing SIP signaling negotiation course between the two terminals by the SIP protocol stack modules of the application server, first terminal and second terminal; 3. completing MSRP file contents transmitting course between the two terminals by their MSRP protocol stack modules. And the invention implements file transmission between any Internet terminals and supports breakpoint transmission.

Description

technical field [0001] The present invention relates to the data transmission technology in the field of Internet communication, relate in particular to the system and its system for realizing file transmission based on SIP (Session Initiation Protocol, initial session protocol) and MSRP (MessageSession Relay Protocol, message session relay protocol) in message session method. Background technique [0002] With the continuous expansion of the Internet field, there are more and more related applications, and the demand for file information exchange between various terminals is also increasing. [0003] At present, the general file transfer technology is limited to terminals of the same type, and it is difficult to meet the requirements between terminals of different types, such as between mobile phones and PCs (Personal Computers), between PDAs (Personal Digital Assistants, personal digital assistants) and PCs. Between mobile phones and PDAs, there is a need for file informa...
