Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Some non-CPM services (such as MMS services, etc.), like CPM services, can carry information based on media content such as text, pictures, audio/video clips, etc. Therefore, non-CPM services and CPM services have certain commonality. However, the method of transmitting content information for non-CPM services is different from that of CPM services. For example, MMS services encapsulate MMS messages into MMS PDUs for transmission, while CPM services transmit CPM messages and streaming media through the following message transmission technologies:

1) Use the SIP (Session Initiation Protocol, Session Initiation Protocol) MESSAGE method to transmit the CPM page mode message;

2) Use SIP INVITE method to set up MSRP (Messaging Session Relay Protocol, message session relay protocol) media mode to transmit CPM large mode message and CPM session mode message;

3) Use the SIP INVITE method to establish the RTP (Real Time Transport Protocol, Real Time Transport Protocol) streaming media mode to transmit real-time audio streams and video streams.

The embodiment of the present invention selects the transmission mode according to the content of the non-CPM service, and then uses the selected transmission mode to send the non-CPM service to the CPM user, so that the CPM system can perform service interworking with the existing non-CPM system.

Among them, non-CPM business includes MMS business, SMS (Short Message Service, short message service) business, IMPS (Instant Messaging and Presence Service, instant message and presence service) business, IM (InstantMessaging, instant message) business, PoC (Push to talk Over Cellular) business, Email business, PSTN (Public Switched Telephone Network, public switched telephone network)/PLMN (Public Land Mobile Network, public land mobile network) voice or video, etc.

Referring to the schematic diagram of the system for transmitting non-CPM services provided in FIG. 1 , the CPM system includes an interworking functional entity 100 , a CPM client 200 , and a CPM meeting server 300 . Among them, the interworking function entity 100 is used to provide the capability of interworking between CPM services and non-CPM communication services, and its functions are as follows:

1) converting the CPM message and CPM session invitation from the CPM meeting server 300 into corresponding non-CPM messages or non-CPM session invitations, and sending the converted messages or sessions to the corresponding system;

2) receiving the response returned by the non-CPM system; converting the messages and session invitations from the non-CPM system into CPM messages and session invitations, and sending them to the CPM conversation server 300;

3) Mapping of transmission notification and reading report between CPM business and non-CPM business;

4) Match the CPM session management request/reply with the non-CPM session request/reply between the CPM service and the non-CPM service.

Taking the system provided in FIG. 1 as an example, the following specifically describes how the interworking functional entity 100 processes CPM messages and streaming media to send to non-CPM systems, and how to receive and process messages or streaming media from non-CPM systems. Messaging sends non-CPM traffic to CPM clients.

Example 1

Referring to Fig. 2, the present embodiment provides a method for transmitting non-CPM services, taking the MMS system for transmitting services to the CPM system as an example, the method includes:

101: The interworking function entity 100 receives a multimedia message from the MMS system;

102: Check the content of the multimedia message, and judge whether the content of the multimedia message only includes simple types of media such as text content information and/or emoticons, if yes, perform 103; otherwise, perform 104;

103: Choose to use the CPM page mode to transmit the content of the multimedia message, that is, convert the multimedia message into a single or multiple CPM page mode messages, and send them to the CPM user with the SIP MESSAGE method;

104: Determine whether the multimedia message contains audio or video clips, if yes, execute 105; otherwise, execute 106;

If the multimedia message contains richer content types (pictures, binary files, audio/video clips, etc.) Establish MSRP media mode or RTP streaming media mode to transmit the content of multimedia messages; if the received multimedia message does not contain audio/video clips, you cannot choose to establish RTP streaming media mode;

105: Determine the transmission mode according to the pre-stored service operator's policy and the preference information of the CPM user. If it is determined that the transmission mode is RTP streaming media mode, execute 109; if it is determined that the transmission mode is MSRP media mode, execute 106;

If the received multimedia message does not contain audio/video clips (including rich content types such as pictures and binary files), or if the received multimedia message contains audio/video clips and the service operator's policy and/or CPM user preference wants to use If the content of the multimedia message is transmitted in the form of MSRP message or file, the interworking functional entity will select the MSRP media mode, which can be established in advance by sending a SIP INVITE request to the CPM user to establish a SIP session;

106: Check whether the size of the multimedia message content exceeds a preset threshold, which is usually set to the maximum value allowed by the message body of a single MSRP message, if not, go to step 107; otherwise, go to step 108;

107: Utilize the content of the multimedia message to construct a single MSRP SEND message, then send this message to the CPM conversation server 300 through an MSRP interaction, and finally send it to the CPM user;

108: Adapt and segment the content of the multimedia message to construct multiple MSRP SEND messages, then send the multiple MSRP SEND messages to the CPM conversation server 300 through multiple MSRP interactions in the CPM session, and finally send them to the CPM user;

109: After selecting the RTP streaming media mode, extract the audio/video clips in the multimedia message, cache them in the form of audio/video files, and play the audio/video clips in the multimedia message via the CPM meeting server 300 in the form of RTP streaming media to the CPM users;

Wherein, the RTP streaming mode can be established in advance by sending a SIP INVITE request to the CPM user to establish a CPM session. For the message content except the audio/video segment in the multimedia message, it can be transmitted using the CPM page mode or the MSRP media mode. The transmission method is the same as above, and will not be described in detail here.

On the basis of the above method, the present embodiment also provides a method for sending the CPM message or conversation sent by the CPM user to the MMS user, and the method is briefly described as follows:

1) If the CPM user wants to send streaming media (real-time voice stream, real-time video, playing audio/video files, etc.) to the MMS user, then initiate a SIP INVITE request to set up the RTP streaming mode.

2) Because current MMS-based systems rarely support streaming media transmission, the interworking functional entity will accept the SIP INVITE request on behalf of the target MMS user after receiving the above-mentioned SIP INVITE request, and establish an RTP stream with the CPM user media mode.

3) When receiving the RTP streaming media sent by the CPM user, the interworking functional entity caches it in the temporary media storage and stores it in the form of audio/video files until the CPM user finishes sending the streaming media.

4) The interworking function entity 100 uses the received SIP INVITE request and the cached streaming media to construct a multimedia message, that is, constructs the message header of the MMS PDU according to the INVITE request, and uses the cached streaming media as the message body. When constructing a multimedia message, the interworking functional entity 100 checks the content and size of the streaming media, and if the size of the streaming media exceeds the maximum value allowed by a single multimedia message, multiple multimedia messages are constructed; if the format type of the content of the streaming media is not specified If supported by the MMS service, adapt the content format of the streaming media to make it conform to the content format type supported by the MMS service. Finally, the interworking function entity 100 sends the multimedia message to the MMS system.

If the service that the CPM user wants to send is not streaming media, but text messages or pictures, etc., the interworking function entity 100 can choose other transmission methods to send the service to other systems (including MMS systems), for example, if it is a text message , it is sent by short message, and if it is a picture or a short video, it is sent by attachment (eg, email).

On the basis of the above method, this embodiment also provides a method for mapping transmission reports and reading reports between the CPM service and the MMS service, the method including:

1) If the CPM user requests the delivery report and/or reading report in the page mode message sent by it, the interworking function entity 100 will include X-Mms-Delivery-Report in the MMS PDU when converting the page mode message into a multimedia message And/or the X-Mms-Read-Report header field and the value is set to "Yes"; wherein, X-Mms-Delivery-Report corresponds to the delivery report, X-Mms-Read-Report corresponds to the reading report, and the interworking functional entity 100 receives After the transmission report and/or reading report returned by the MMS system, use the IMDN (Instant Message Disposition Notification, instant message indication notification) mechanism to construct a SIP MESSAGE request to send the transmission report or reading report to the CPM user;

2) If the CPM user requests a success/failure transmission report in the MSRP SEND message sent by it, that is, the "Success-Report" header field value or the "Failure-Report" header field value in the MSRPSEND message is "Yes", the interworking functional entity When converting the MSRP SEND message into a multimedia message, include the X-Mms-Delivery-Report header field in the MMS PDU and set the value to "Yes"; after the interworking function entity 100 receives the delivery report returned by the MMS system, it constructs the MSRPREPORT message to send delivery reports to CPM users;

3) The CPM user sends the streaming media to the interworking functional entity 100, and the interworking functional entity 100 knows that interworking is required, then by setting the CPM user preference, the interworking functional entity requests the transmission report and/or reading report in the multimedia message sent by it ;After receiving the transmission report and/or reading report returned by the MMS system, the interworking functional entity can request to transmit the transmission report or reading report to the CPM user through the IMDN mechanism or other out-of-band mechanisms;

4) If the MMS user requests the transmission report and/or reading report in the multimedia message sent by the MMS user, the interworking functional entity shall perform the following analysis and processing:

A: If the multimedia message is converted into a page mode message, the interworking functional entity 100 requests the transmission report and/or reading report in the SIP MESSAGE request; when receiving the MESSAGE request returned by the CPM user using the IMDN mechanism, the interworking functional entity converts it Send notifications and/or reading reports for MMS and send them to the MMS system;

B: If the multimedia message is converted into an MSRP message, the interworking functional entity 100 requests a success/failure report ("Success-Report" header field value or "Failure-Report" header field value is "Yes") in the MSRP SEND message, and When receiving the MSRP REPORT message returned by the CPM user, construct an MMS transmission report and send it to the MMS system; because the MSRP protocol does not support the reading report, the interworking functional entity 100 can return a failure response corresponding to the reading report, or send it through other out-of-band notification mechanisms Realize the reading report;

C: If the interworking function entity 100 sends the audio/video segment in the multimedia message to the CPM user in the form of streaming media, when receiving the signal that the streaming media is played, it can construct an MMS transmission notification and a reading report, and send them to the MMS user.

This embodiment discriminates the content and size of the multimedia message, and selects a certain message session transmission method to transmit the content of the multimedia message to the CPM user through the discrimination result, so that the message between the CPM user and the MMS user is communicated, and solves the problem The mapping of the MMS PDU sent by the MMS user to the various message transmission technologies supported by the CPM, and the realization of the problem that the CPM user sends streaming media to the MMS user and receives the content of the multimedia message in the form of streaming media, and realizes the inclusion of the two services Multimedia content messages and even streaming media intercommunication requirements, so as to provide better user experience and optimize the use of network resources.
