Background technology
At IMS(IP Multimedia Subsystem, IP Multimedia System) in the service application of core net, there are at present two kinds of instant message patterns, common instant message and large message, common instant message is that the content of carrying user's transmission in message body (body) the inside by MESSAGE message sends to the application server (or being called service server) of the business of realization, then is forwarded to recipient by service server.And large message mode is by INVITE(invitation message) initiation session carries out media negotiation link setup with recipient, by MSRP(Message Session Relay Protocol, message session trunk protocol) as application layer protocol, come transmitting user data to complete the mutual of message.
Subscriber equipment, core net, application server (Application Server, abbreviation AS) position in network as shown in Figure 1, two subscriber equipment (User Equipment of interacting message, abbreviation UE) A is connected with application server by core net with B, between core net and application server, pass through SIP(Session Initial Protocol, session initiation protocol) message is carried out media negotiation, after consulting successfully, directly set up link with application server, by application server, forward MSRP message and reach the object that sends large message.In figure, application server should be two equipment in logic, is respectively the service server at UE A and UE B place.
As shown in Figure 2, in figure, UE and application server interaction message transmit by IMS core net existing large message transmission flow, and IMS core net just forwards message, therefore omitted core net in figure.In Fig. 2, UE A initiates INVITE request, in request, carry media description information (Session Description Protocol, be called for short SDP) for carrying the media capability of local terminal, this INVITE request is transmitted to UE B by AS, UE B carries the media capability of local terminal in 200 OK message, then is transmitted to UE A by AS, and UE A and UE B have just completed media negotiation like this, then A sends to UE B by MSRP link setup by large message, and centre forwards by AS.
The maximum difference of common instant message and large two kinds of modes of message is that the message-length of common instant message has certain limitation, can only send common text, and large message is owing to being the mode of link setup through consultation, sends the not restriction of content and length.That is to say that sending the text message that length is less than certain value (as 1156 bytes) can be realized by common instant message, and send when the files such as picture, audio frequency and video or length surpass the text message of certain value, must realize by the mode of large message.
And the MESSAGE message of common instant message arrives after recipient's service server when recipient is not online, recipient's IM(Instant Message, instant message) process judges whether recipient registers on service server, if registration, just MESSAGE message is sent to recipient, if not registration, just message stores is arrived to service server, when recipient reaches the standard grade the registration of backward service server, service server is received after the message that this user reaches the standard grade in database query history message and is handed down to recipient.And large messaging service server is only responsible for forwarding INVITE, when recipient is not online, consulting cannot be successful, cannot send the large message of off-line, also just cause user to want to send large message must transmit leg simultaneously online with recipient, function be used the very large limitation of existence.
