Embodiment Construction
[0020] In order to make the purpose, technical features and implementation effects of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] With the application of the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem), a better service experience can be obtained by realizing the intercommunication between the communication network and the Internet during the communication process. On the basis of various existing network protocols, the present invention A method and device for sending and receiving real-time multimedia information are implemented through less expansion of the network protocol, and the transmission process is initiated based on the Session Initiation Protocol (SIP, Session Initiation Protocol) and the Session Description Protocol (SDP, Session Description Protocol), and through Real-time Transport Protocol (RTP, Real-ti...

The invention provides a method and a device for receiving and sending instant multimedia information, wherein, the method includes the following steps: step A, a sending terminal divides the instant multimedia information into a plurality of real-time transport protocol media packages, and real-time transport protocol media packages are transmitted to an instant multimedia information server through the network; step B, the instant multimedia information server stores the instant multimedia information, and through the network transmits the real-time transport protocol media packages of the instant multimedia information to a receiving terminal which is on line. By applying the technology provided by the invention, no special server is needed to be arranged in case that a third-party is not available, and based on related protocols such as the initial conversation protocol, real-time transport protocol, etc., a smooth receiving and sending of various instant multimedia information can be achieved between two terminals positioned at different networks by simply expending the existing related protocol. Furthermore, the technology also supports sending instant multimedia information through multicast and broadcast.
Description
technical field [0001] The invention relates to information exchange technology in the communication field and the Internet field, in particular to a method and device for sending and receiving instant multimedia information. Background technique [0002] With the extensive development of communication technology, the connection between people is more and more dependent on various means of communication, among which sending and receiving multimedia information has become an important means of communication, and multimedia information (such as commonly called MMS) in The second-generation mobile communication technology is usually realized by technology based on Wireless Application Protocol (WAP, Wireless Application Protocol). This technology needs to set up a multimedia information service center (MMSC, Multimedia Messaging Service Center), value-added service MMS, MultiMedia Service) application support system; but the above technologies for sending and receiving multimed...
