Problems solved by technology
At present, in the transmission of large message mode CPM messages, how to implement MSRP parameters in media negotiation, that is, MSRP connection parameters (connection parameters are IP address, port number and / or URI parameters) negotiation, has not given a specific implementation plan, that is to say, Currently, the implementation of large message mode CPM message transmission is incomplete. It does not provide how the control functional entity participates in the media negotiation process, and how each functional entity obtains the MSRP connection parameters of the adjacent functional entity that will establish a link with it during the negotiation process. implementation plan

[0045] figure 1 It is the flow chart of the method for realizing MSRP parameter negotiation in the present invention to transmit the large message mode CPM message, as figure 1 As shown, in the process of transmitting the large message mode CPM message to the group, it includes:
[0046] Step 100: Carry the MSRP connection parameter in the SDP message in the session invitation message, and / or carry the MSRP connection parameter in the SDP message in the success response message.
[0047] Step 101: Each functional entity participating in the transmission of the large message mode CPM message obtains the MSRP connection parameters of the adjacent functional entity with which the link is established through the received session invitation message and / or success response message.
[0048] In the present invention, the group may be a preset group or a temporary group.
[0049] The functional entities participating in the transmission of CPM messages in the large message mode incl...

The invention provides a method and a system for realizing MSRP (Message Session Relay Protocol) parameter negotiation in transmission of a large message mode converged IP messaging (CPM). In the process of transmitting the large message mode CPM to a group, each function entity participating in the transmission of the large message mode CPM acquires MSRP connection parameters of the adjacent function entities which establish links with each function entity through the MSRP connection parameters carried by a session description protocol (SDP) message in a session invitation message and / or the MSRP connection parameters carried by the SDP message in a successful response message to complete the media negotiation process in the transmission of the large message mode CPM, thereby completely realizing the sending of the large message mode CPM.
Description
technical field [0001] The present invention relates to, especially a kind of global information required for realizing the message session relay protocol (MSRP, TheMessage Session Relay Protocol) multi-hop transmission in the media negotiation of the large message mode fusion IP message (CPM, Converged IP Messaging) to the group A method and system for resource identifier (URI) parameter negotiation. Background technique [0002] In order to realize the intercommunication of various messaging services, provide a unified messaging service, and provide a consistent and convenient messaging service experience, the Open Mobile Alliance (OMA, Open Mobile Architecture) proposed CPM in 2005. CPM integrates various existing message services, including instant message (IM, InstantMessage), push-to-talk (POC, Push-To-Talk over Cellular), mobile email (MEM, Mobile E-Email), short message service (SMS, Short Messaging Service), MMS (MMS, Multimedia Messaging Service), etc. [0003] A...
