Abstract
The method comprises: a) the session initiation protocol is used to pack a multi media message and complete the negotiation before transmission; b) the transmission control protocol is used to transmit multi media message; if the multi media message is an instant multi media message, then makes an instant transmission; if the multi media message is a non-instant multi media message, then makes storage-forwarding. Said transmission control protocol is used in the fixed wideband network.
Description
Technical field
The present invention relates to the communication technology, particularly a kind of method for transmitting message in multimedia.
Background technology
The Multimedia Message of prior art is MMS, is mainly used in moving communicating field, as GPRS/GSM/UMTS etc., as under the support of GPRS network, is that carrier transmits video, picture, sound and literal with WAP.And the MMS message file mainly is asynchronous transmission, is the non-instant messages that the local side storage is transmitted.
At present 3GPP is also in the MMS standard of working out based on the IP transmission, but what adopt is Transmission Control Protocol at wireless broadband network.Employing has been done the Transmission Control Protocol of optimization as transport layer protocol at the characteristic of wireless network.According to the difference of the business that provides, the communication between MMS user agent and the MMS relay/server can be used application layer protocols such as SMTP, POP3, IMAP4 and HTTP.But MMS does not use in broadband network, especially fixed broadband network.
Session initiation Protocol is the application layer control protocol that SIP (Session Initiation Protocol) is based on IP.Because SIP is based on the signaling protocol of plain text, the terminal that can manage different access networks.
Summary of the invention
Technology solved by the invention is that a kind of method that transmits MMS in fixed broadband network is provided.
The present invention solves the problems of the technologies described above the technological means that is adopted to be, method for transmitting message in multimedia may further comprise the steps:
A, employing Session initiation Protocol encapsulate Multimedia Message, finish and transmit preceding the negotiation;
B, employing transmission control protocol transmit Multimedia Message.
If Multimedia Message is that instant multimedia message then transmits immediately; If Multimedia Message is that non-instant multimedia message is then stored forwarding.
Described transmission control protocol is used for fixing broadband network.
The invention has the beneficial effects as follows, expanded the application of MMS, feasible various terminals (fixed terminal/wireless terminal) based on the IP broadband networks can realize that also MMS uses.
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 realizes the system block diagram that Multimedia Message transmits for the present invention;
Fig. 2 transmits flow process for Multimedia Message of the present invention.
Embodiment
Embodiment
As shown in Figure 1, terminal A and terminal B acting server and the immediate service platform by separately communicates.Instant MMS message file based on SIP between terminal A, B transmits flow process, and as shown in Figure 2, MMS information adopts text formatting, and SIP is adopted in terminal A, the B negotiation before formal transmission, and negotiations process and content all adopt the SIP MESSAGE signaling of standard.The MESSAGE200OK denoting signaling recipient of sip message bunch correctly receives the push-notification-answer after the message, (1) to (11) sends preceding negotiation for the MMS message file in the following steps, not only be the processing of message header and message body with the negotiation difference before other the TCP message transfer, also be passing through to adopt SIP MESSAGE signaling after application layer realizes consulting, comparison close friend's interactive interface can be provided, simultaneously when the needs transformation strengthens user interface, need not transform bottom TCP/IP stack, and the SIP MESSAGE signaling that only need revise application layer gets final product.
(1) terminal A sends the MESSAGE request to acting server, and request transmits file to terminal B;
(2) acting server is transmitted the MESSAGE request to terminal B, tells it, and terminal A request transmits file to terminal B;
(3) terminal B finally replys to acting server transmission " 200OK ";
(4) acting server self terminal B in future " 200OK " finally replys and is transmitted to terminal A;
(5) terminal B sends the MESSAGE request to acting server, agrees that the file of A transmits request;
(6) acting server is transmitted the MESSAGE request to terminal A, tells it, and B agrees that the file of A transmits request;
(7) terminal A finally replys to acting server transmission " 200OK ";
(8) acting server self terminal A in future " 200OK " finally replys and is transmitted to terminal B;
(9) terminal A sends the MESSAGE request to acting server, tells B with the ip address and the port that oneself are prepared for transmitting file.
(10) acting server is transmitted the MESSAGE request to terminal B, and ip address and the port that A is prepared for sending file carried in this request;
(11) terminal B initiates ip address from the TCP test to A and port, and the TCP handshake procedure is followed in this test, is used for confirming address and the port of B and A;
(12) terminal A transmits file to terminal B, generally adopts TCP to transmit.
Acting server has the storage forwarding capability, realizes transmission and reception based on the non-instant MMS information of SIP.
MMS storage forwarding server operation principle based on SIP is as follows:
When receiving that terminal A is when terminal B sends out the MESSAGE request of MMS information, to the presence of registrar inquiry terminal B;
If terminal B is online, then the MESSAGE request is transmitted to terminal B, terminal B will set up passage with terminal A, and the MMS message file is carried out one-way transmission;
If terminal B is not online, then sets up the MMS message file and transmit session, and the MMS message file is preserved by this acting server and A; After this, when terminal B reached the standard grade, this acting server sent the MMS message file to B and transmits request, and the MMS message file is sent to terminal B.
Transmit MMS information in IP network, can be by MMS information be carried out the safety that asymmetric encryption encapsulates guarantee information.
Terminal generates pair of secret keys, i.e. PKI and private key.Terminal only needs in advance the PKI of oneself to be informed that all friends get final product.When terminal B sent message, terminal A can adopt the private key of A that message is encrypted to terminal A, also can adopt the PKI of B that message is encrypted at every turn; Otherwise, when terminal B receives from the message of A,, then encrypt with the PKI of the A that obtains in advance if the message encryption employing is the private key of A, if employing is the PKI of B, then the private key with B oneself is decrypted.
As use public-key cryptography that file is carried out encrypted transmission:
Terminal A generates an own private cipher key and also with the public-key cryptography of terminal B the private cipher key of oneself is encrypted, simultaneously terminal A encrypts with own private cipher key the file of needs transmission, then by the file transfer of network after encryption to terminal B;
After using the public-key cryptography of oneself to be decrypted, terminal B obtains the private cipher key of terminal A; Terminal B is decrypted file with the private cipher key of terminal A.
Because have only reception to have the public-key cryptography of oneself just now, thus even other people have obtained the private cipher key through the transmit leg of encrypting, also guaranteed the fail safe of private cipher key because can't be decrypted, thus also guaranteed the fail safe of transfer files.
