Description

A system for sending instant message reports in an instant message system

technical field

The invention relates to instant message technology, in particular to a method for sending an instant message report in an instant message system.

Background technique

The instant messaging (Instant Messaging, IM) service belongs to a mobile data service based on presence (Presence) person-to-person or person-to-group messaging.

The Open Mobile Alliance (OMA) International Standards Organization has formulated standards for mobile instant messaging. There are two types of instant messaging systems in the current version of the standard specification: the first type is based on the Wireless Village (WV) protocol The instant messaging system based on Hyper Text Transport Protocol/Wireless Access Protocol/Short Message Service (Hyper Text Transport Protocol/Wireless Access Protocol/Short Messaging Service, HTTP/WAP/SMS) bearer protocol can support 2.5G/3G network The second type is an instant messaging system based on the ISP/ISP Instant Messaging and Field Support Extension (Session Initiated Protocol/SIP InstantMessage and Presence Leveraging Extensions, SIP/SIMPLE) protocol, the system is based on the protocol carried by SIP/SIMPLE , support IP network based on Internet Protocol (Internet Protocol, IP) Multimedia Subsystem (IP Multimedia Subsystem, IMS).

In the existing SIP/SIMPLE system, when the receiving end user is online, the sending end user can send an instant message through the IM system, and request the receiving end to send an instant message report, and the receiving end user can obtain and read the instant message in time, so as to be able to reply Instant message report. The sending end knows whether the sent instant message is successfully delivered to the receiving end or whether it is read by the user of the receiving end through the reply instant message report.

However, in the prior art, in some cases, the receiving end of the SIP/SIMPLE system cannot send instant message reports such as successful delivery report, failed delivery report and reading report to the user who sent the instant message, for example: the sending end user sends an instant message When the receiving end user is offline, the receiving end user obtains offline messages after going online; the receiving end user reads instant messages after the message session relay protocol (Message Session Relay Protocol, MSRP) data channel is disconnected; the IM server deletes the offline messages stored over time. message; the receiving end user does not obtain the instant message, but directly deletes the instant message from the IM server.

It can be seen that the existing technology cannot realize that the receiving end in the SIP/SIMPLE system sends the message to the sending end when the user receives the offline message, the user reads the message after the MSRP data channel is disconnected, the IM server deletes the offline message, and the user deletes the offline message. The instant message report, so that the demand of the sending end user to obtain the instant message report cannot be satisfied, and then the serviceability of the SIP/SIMPLE system is not high.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for sending an instant message report in an instant message system, which can realize sending an instant message report from a receiving end to a sending end under various circumstances.

The sending of the instant message report by the receiving end to the client of the sending end is: the sending of the instant message report by the receiving end to the client of the sending end via the instant message server to which the receiving end and the sending end belong.

The instant message servers to which the receiving end and the sending end belong are two different instant message servers.

The method for sending the instant message report to the client at the sending end side via the receiving end and the instant messaging server to which the sending end belongs includes:

A1. The receiving end sends an instant message report to the instant message server to which the receiving end belongs;

A2. The instant message server to which the receiving end belongs sends an instant message report to the instant message server to which the sending end belongs;

A3. The instant message server to which the sending end belongs sends an instant message report to the sending end.

The instant message report is a successful delivery report;

Before the receiving end side judges, it further includes: when the client at the receiving end side is offline, the sending end sends an instant message including an instant message report request to the client at the receiving end side, and the instant message server to which the receiving end belongs stores the information. instant message;

After the client at the receiving end goes online, it obtains the instant message sent by the sending end from the instant message server to which the receiving end belongs.

If there is no message session relay protocol data channel connection between the instant message server to which the receiving end belongs and the sending end, the steps A1 and A2 further include: the instant messaging server to which the receiving end belongs initiates the establishment of all message sessions with the sending end Relay protocol data channel;

The method for sending the successful delivery report is: sending the successful delivery report through the message session relay protocol data channel.

The storage of the instant message by the instant message server is: the instant message server stores the instant message in its own offline message storage unit.

The instant message report is a reading report;

Before the judgment is made on the receiving end side, it further includes: the receiving end establishes a message session relay protocol data channel with the instant server to which the receiving end belongs, and obtains the instant message including the instant message report request sent by the sending end through the message session relay protocol data channel. message, and read said instant message after the message session relay protocol data channel is disconnected.

If there is no message session relay protocol data channel connection between the instant message server to which the receiving end belongs and the sending end, before the step A1 further includes: the receiving end initiates the establishment of all message session relay protocol data channels between the sending end;

The method for sending the reading report is: sending the reading report through the message session relay protocol data channel.

The step A1 is: the receiving end sends the instant message report to the instant message server to which the receiving end belongs via the SIP/IP core network to which the receiving end belongs;

The step A2 is: the instant message server belonging to the receiving end sends the instant message report to the instant messaging server belonging to the sending end via the SIP/IP core network belonging to the receiving end and the SIP/IP core network belonging to the sending end;

The step A3 is: the instant message server to which the sender belongs sends the instant message report to the sender via the SIP/IP core network to which the sender belongs.

The method for sending the instant message report to the client at the sending end side via the receiving end and the instant messaging server to which the sending end belongs includes:

B1. The instant message server to which the receiving end belongs sends an instant message report to the instant message server to which the sending end belongs;

B2. The instant message server to which the sending end belongs sends an instant message report to the sending end.

The instant message report is a failed delivery report;

The method further includes: the instant message server to which the receiving end belongs or the receiving end deletes the instant message including the instant message report request stored in the instant message server before the judgment is made on the receiving end side.

If the instant message server to which the receiving end belongs is not connected to the sending end through the message session relay protocol data channel, before the step B1, it further includes: the instant messaging server to which the receiving end belongs initiates the establishment of all message session relays with the sending end protocol data channel;

The method for sending the delivery failure report is: sending the delivery failure report through a message session relay protocol data channel.

The step B1 is: the instant message server belonging to the receiving end sends the instant message report to the instant messaging server belonging to the sending end via the SIP/IP core network belonging to the receiving end and the SIP/IP core network belonging to the sending end;

The step B2 is: the server to which the sender belongs sends the instant message report to the sender via the SIP/IP core network to which the sender belongs.

The instant message server to which the receiving end and the sending end belong is the same instant message server.

The sending of the instant message report to the client at the sending end by the receiving end includes:

The receiving end establishes a message session relay protocol data channel with the instant message server to which the receiving end belongs, and sends an instant message report to the instant message server to which the receiving end belongs through the message session relay protocol data channel;

The instant message server to which the receiving end belongs establishes a message session relay protocol data channel with the sending end, and sends an instant message report to the sending end through the message session relay protocol data channel.

The receiving terminal side sends the instant message report to the client side of the transmitting terminal as follows: the receiving terminal establishes a message session relay protocol data channel with the transmitting terminal, and transmits the instant message report to the transmitting terminal through the message session relay protocol data channel Send an instant message report.

It can be seen from the above technical solution that the technical solution of the present invention sends the instant message report to the client at the sending end side after the receiving end side determines that the received instant message contains a request to send a report, so that when the user receives the offline message , When the user reads the message after the MSRP data channel is disconnected, the IM server deletes the offline message, and the user deletes the offline message, the receiving end in the SIP/SIMPLE system sends an instant message report to the sending end user, which satisfies the requirements of the sending end. The user needs to obtain instant message reports, thereby improving the serviceability of the SIP/SIMPLE system.

Detailed ways

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

The basic idea of the present invention is: the receiving end side sends the instant message report to the client side at the sending end side after judging that the received instant message contains an instant message report request.

Fig. 1 is a flowchart of an exemplary method for sending an instant message report in the present invention. As shown in Figure 1, the method for sending instant message report of the present invention comprises the following steps:

Step 101, the receiving terminal side judges whether the received instant message contains an instant message report request, and if so, executes step 102;

Step 102, after the receiving end determines that the received instant message includes an instant message report request, it sends the instant message report to the client at the sending end.

Fig. 2 is a structural diagram of the SIP/SIMPLE system. As shown in Figure 2, taking two networks A and B as examples, the SIP/SIMPLE system for implementing IM services in the prior art includes: IM server A 201 belonging to network A, SIP/IP core network A 202 and n clients A terminal A 203, an IM server B 204 belonging to a network B, a SIP/IP core network B 205 and n clients B 206.

The IM server A 201 can carry out information interaction with the client A 203 and the SIP/IP core network A 202 respectively, store the instant messages sent by other clients to the client A after the client A goes offline, and store the instant messages after the timeout Delete this message; IM server B 204 can carry out information interaction with client B 206 and SIP/IP core network B 205 respectively, store the instant message sent to client B 206 by other clients after client B 206 goes offline, and in The message is deleted after the timeout of storing the instant message. The IM server A 201 and the IM server B 204 in the two networks can exchange information, and both can send instant messages to multiple receiving users or predefined groups; SIP/IP core network A 202 and SIP/IP IP core network B 205 can carry out information exchange, SIP/IP core network A 202 and SIP/IP core network B 205 can also carry out information with client A 203 and IM server A 201, client B 206 and IM server B 204 respectively interact.

Next, through several specific embodiments, the method for sending an instant message report through the MSRP data channel and the SIP/IP core network of the present invention will be described respectively.

Embodiment one

FIG. 3 is a flowchart of a method for sending an instant message report in Embodiment 1 of the present invention. In this embodiment, the servers to which the sending end and the receiving end belong are IM server A and IM server B respectively; the client B of the receiving end is offline, but can receive offline messages after going online; the instant message report is sent through the MSRP data channel of. As shown in Figure 3, the method for sending an instant message report in this embodiment includes the following steps:

Step 301, user A requests to send an instant message to user B, and client A sends an invitation (SIP INVITE) message based on the initial session protocol to IM server A according to the request of user A, and establishes an MSRP data channel with IM server A , and similarly, establish an MSRP data channel between IM server A and IM server B.

In steps 302 to 303, the client A sends the MSRP SEND message to the IM server B through the IM server A.

Since client B is offline at this time, the MSRP SEND message sent by IM server A is an offline message.

Among them, the MSRP SEND message includes: the identity code (Message-ID) of the message, the successful delivery report (Success-Report: yes) that needs to be replied; the message header such as the failure delivery report (Failure-Report: yes) that needs to be replied and the sent message, etc. .

Step 304～Step 305, IM server B stores the offline message, and replies with MSRP 200 "OK" message to IM server A, indicating that IM server B has received the offline message, and IM server A forwards the received MSRP 200 "OK" message to client A.

Among them, the MSRP 200 "OK" message only means that the offline message has been received, and does not mean that the offline message has been successfully sent to client B as the destination client.

The IM server B includes an online message storage unit and an offline message storage unit, and the offline messages in this embodiment are stored in the offline message storage unit. The online message storage unit and the offline message storage unit may constitute an IM server, or may be two servers respectively.

Step 306, client A disconnects the MSRP data channel by sending a bye (SIP BYE) message based on the initial session protocol to IM server A.

The reason why client A disconnects the MSRP data channel may be: the instant message report is not received after waiting for a certain period of time, and the MSRP data channel is disconnected in order to save network resources.

Step 307, after the user B goes online through the client B, request to obtain the offline message from the IM server B by means of PUSH.

User B may also request to obtain offline messages in a PULL manner.

In step 308, the client B establishes an MSRP data channel with the IM server B by sending a SIP INVITE message to the IM server B.

In steps 309 to 310, IM server B sends an MSRP SEND message including an offline message to user B to client B. After receiving the offline message, client B sends an MSRP 200 "OK" reply message to IM server B, indicating offline The message was successfully sent to the destination client.

In steps 311 to 312, client B judges that the received offline message needs to send a successful delivery report to client A as the sender according to the successful delivery report request in the message header of the MSRP SEND message, and thus passes the undisconnected MSRP The data channel sends the report (MSRP REPORT) message based on the message session relay protocol including the successful delivery report to the IM server B, and the IM server B responds to the client B with MSRP 200 "OK" after receiving the MSRP REPORT message, Indicates that a MSRP REPORT message has been received.

The MSRP REPORT message also includes information such as the Message-ID and summary description in the offline message.

Step 313, client B disconnects the MSRP data channel between IM server B and client B by sending a SIP BYE message to IM server B.

Step 314, after the IM server B finds that the MSRP data channel has been disconnected, it sets up the MSRP data channel with the IM server A by sending a SIP INVITE message to the IM server A, and similarly, between the IM server A and the client A. Create an MSRP data channel.

In steps 315 to 316, the IM server B sends the MSRP REPORT message including the successful delivery report to the client A through the IM server A.

In steps 317 to 318, after receiving the successful delivery report in the MSRP REPORT message, client A sends an MSRP 200 "OK" message to IM server B through IM server A, indicating that the MSRP REPORT message has been successfully received.

Step 319, disconnect the MSRP data channel for sending the message delivery report.

In this embodiment, the successful delivery reports sent in step 311 and steps 315 to 316 may also be sent through MSRP SEND messages. At this point, it is necessary to encapsulate the content type of the successful delivery report with the general format message type (MESSAGE/CPIM) content type (Content-type) of the instant message: instant message delivery report eXtensible Markup Language (eXtensible Markup Language, XML) message type ( message/imdn+xml); content disposition (Content-Disposition): notification (notification), and use the content of XML to indicate the relevant information of the successful delivery report, such as the Message-ID of the received message, the content of the report, the time of the received message Summary description and other information.

In this embodiment, if the client is ready to send a successful delivery report, the IM server B disconnects the MSRP data channel after sending the offline message, and the client B can also send the delivery through a message (SIP MESSAGE) based on the initial session protocol. For a successful report, use the MESSAGE/CPIM content type to encapsulate the content type of the delivery report: message/imdn+xml; Content-Disposition: notification, and use XML content to represent the relevant information of the successful delivery report, such as the Message-ID of the received message, Information such as report content, time, and a summary description of the received message. Now, change step 311 to: establish MSRP data channel between client B and client A, IM server B, and IM server A, so as to send a successful delivery report; change step 312 to: client B passes IM server B , sends an MSRP SEND message to IM server A including a successful delivery report.

The present embodiment sets up the MSRP data channel by the SIP INVITE message, also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, also can disconnect the MSRP channel by other messages.

In this embodiment, the successful delivery report may not be sent through the IM server A, and the MSRP data channel between the IM server B and the client A may be directly established, and the IM server B sends the successful delivery report to the client A, or it may be established In the MSRP data channel between client B and client A, client B directly sends a successful delivery report to client A.

This embodiment realizes the sending of the successful delivery report, and is also applicable to the sending of other types of delivery reports and reading reports.

Embodiment two

The successful delivery report in the first embodiment is sent by establishing the MSRP channel and sent by the MSRPREPORT message; in practical applications, the MSRP channel may not be established and sent by the SIP MESSAGE message, which constitutes the second embodiment of the present invention .

FIG. 4 is a flowchart of a method for sending an instant message report in Embodiment 2 of the present invention. In this embodiment, the servers to which the sending end and the receiving end belong are IM server A and IM server B respectively, and the client B of the receiving end is offline, but can receive offline messages after going online, and the sending is successful through the SIP/IP core network Delivery report. As shown in Figure 4, the method for sending an instant message report in this embodiment includes the following steps:

The operation process of step 401 to step 413 is the same as the operation process of step 301 to step 313 in the first embodiment.

In steps 414 to 416, after the IM server B finds that the MSRP data channel has been disconnected, it sends a SIP MESSAGE message including a successful delivery report to the IM server A through the SIP/IP core network B and the SIP/IP core network A in turn.

Among them, the content type of the delivery report is encapsulated by the MESSAGE/CPIM content type: message/imdn+xml; Content-Disposition: the content of notification and XML indicates the relevant information of the successful delivery report, such as the Message-ID of the received message , report content, time, summary description of the received message and other information.

In steps 417 to 418, the IM server A receives the message, recognizes that the SIP MESSAGE message is sent to the client A through the information in the message header, and forwards the SIP MESSAGE to the client A through the SIP/IP core network A.

In steps 419 to 420, after client A receives the delivery success report in the SIP MESSAGE message, it replies a SIP 200 "OK" message to IM server A through the SIP/IP core network A, indicating that it has received the SIP MESSAGE message.

From step 421 to step 423, IM server A sends the SIP 200 "OK" message to IM server B through SIP/IP core network A and SIP/IP core network B in sequence.

In steps 415 to 423, each time a message is forwarded, the route-related information in the message header can be changed according to the message destination information in the message header of the SIP MESSAGE message or the SIP 200 "OK" message, and then proceed Forward.

The present embodiment sets up the MSRP data channel by the SIP INVITE message, and also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, and can also disconnect the MSRP channel by other messages.

This embodiment realizes the sending of the successful delivery report, and is also applicable to the sending of other types of delivery reports and reading reports.

As shown in Figure 5, the method for sending an instant message report in this embodiment includes the following steps:

In step 501, user A wishes to send an instant message to user B. Since the message exceeds the limit of SIP messages or clients, it needs to be sent through the MSRP data channel. Client A sends a SIP INVITE message to establish an MSRP data channel with IM server A. Similarly, An MSRP data channel is established between IM server A and IM server B, and between IM server B and client B.

The limitation of the SIP message in this step is that the IM server cannot send SIP messages larger than 1K bytes, and the limitation of the client is that Client B cannot receive SIP messages larger than 1K bytes.

In steps 502 to 504, client A sends MSRP SEND messages to client B through IM server A and IM server B in turn, including Message-ID, disposition report type is read report (Disposition-Notification: read) and other message headers and sent messages etc.

At this time, since client B as the receiving end is online, the MSRPSEND message sent by client A is an online message.

From step 505 to step 507, client B responds to client A with an MSRP 200 "OK" message through IM server B and IM server A in turn, indicating that the message has been received, but it does not mean that it has been successfully sent to the destination.

Step 508, client B judges that the received message needs to send a reading report to client A as the sender according to the information in the message header of the MSRP SEND message, and client B reports successful receipt to client A through the MSRP data channel message, and send a SIP BYE message through item IM server B to disconnect the MSRP data channel.

Wherein, the reason for disconnecting MSRP may be: client B waits for a period of time without sending a message, or waits for a certain period of time without a message sending request, and disconnects the MSRP data channel in order to save network resources.

Step 509, when user B reads the received instant message through client B, client B judges that the message includes a reading report request according to the information in the message header.

In step 510, an MSRP data channel is established between client B and client A, IM server B, and IM server A, so as to send reading reports.

From step 511 to step 513, the client B sends the MSRP SEND message including the reading report to the client A through the IM server B and the IM server A in turn.

Among them, the content type of the delivery report is encapsulated by the MESSAGE/CPIM content type: message/imdn+xml; Content-Disposition: notification, and the relevant information of the successful delivery report is represented by XML content, such as the Message- ID, report content, time, summary description of the received message and other information.

In this step, the reading report can also be sent through the MSRP REPORT message.

From step 514 to step 516, client A returns MSRP 200 "OK" message to client B through IM server A and IM server B in turn, indicating that MSRP SEND message has been received.

Step 517, client A does not send a message for a period of time, and disconnects all MSRP data channels between client A and client B by sending a SIP BYE message to IM server A.

In this embodiment, all messages are sent and forwarded through the MSRP data channel among client A, IM server A, IM server B and client B.

The present embodiment sets up the MSRP data channel by the SIP INVITE message, also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, also can disconnect the MSRP channel by other messages.

The method in this embodiment is applicable to reading reports after reading online messages, and also applicable to reading reports after reading offline messages. When the method of this embodiment is used to send a reading report after reading offline messages, the operation process of steps 504 to 507 can be replaced with the operation process of steps 304 to 310 in the first embodiment, that is, the process for users to obtain offline messages .

In this embodiment, the reading report may not be sent by the IM server A and the IM server B, the MSRP data channel between the IM server B and the client A may be established, and the reading report is sent to the client A by the IM server B, or Establish an MSRP data channel between client B and client A, and client B directly sends the reading report to client A.

In this embodiment, the delivery failure report may not be sent through the IM server A, but the MSRP data channel between the IM server B and the client A may be directly established, and the IM server B sends the delivery failure report to the client A, or an MSRP data channel may be established. In the MSRP data channel between client B and client A, client B directly sends a delivery failure report to client A.

The method for sending a delivery failure report in this embodiment is applicable to the case where the IM server B deletes the timed-out offline information, and is also applicable to the situation where the user B directly deletes the offline information on the IM server B without obtaining the offline information through the client B.

Embodiment six

After the client B does not obtain the offline message stored in the IM server B for a long time, the IM server B will delete the timed-out offline message at this time, do not establish an MSRP data channel, and send a delivery failure report, which constitutes the present invention Embodiment six.

FIG. 8 is a flowchart of a method for sending an instant message report in Embodiment 6 of the present invention. In this embodiment, the servers to which the sending end and the receiving end belong are IM server A and IM server B respectively, client B is offline, and IM server B sends the failed delivery message through the SIP/IP core network after the timeout of storing the offline message Report. As shown in Figure 8, the method for sending an instant message report in this embodiment includes the following steps:

In step 801, the IM server B saves the offline message of user B for a timeout, deletes the offline message, and finds that the message includes a delivery failure report request according to the information in the message header of the message.

In steps 802 to 804, the IM server B finds that the MSRP data channel has been disconnected, and sends a SIP MESSAGE message including a delivery failure report to the IM server A through the SIP/IP core network B and the SIP/IP core network A in turn.

Among them, the content type of the delivery report is encapsulated by the MESSAGE/CPIM content type: message/imdn+xml; Content-Disposition: notification, and the relevant information of the successful delivery report is represented by XML content, such as the Message- ID, report content, time, summary description of the received message and other information.

In steps 805 to 806, IM server A receives the message, finds that the SIP MESSAGE message including the failed delivery report is sent to client A through the information in the message header, and forwards the SIPMESSAGE to client A through SIP/IP core network A .

In steps 807 to 808, client A receives the delivery report, and replies a SIP 200 "OK" message to IM server A through SIP/IP core network A, indicating receipt of the SIP MESSAGE message.

From step 809 to step 811, IM server A sends the SIP 200 "OK" message to IM server B through SIP/IP core network A and SIP/IP core network B in sequence.

In steps 803 to 811, when forwarding each time, the route-related information in the message header can be changed according to the message destination information in the message header of the SIP MESSAGE message or the SIP 200 "OK" message, and then forwarded .

The method for sending a delivery failure report in this embodiment is applicable to the case where the IM server B deletes the timed-out offline information, and is also applicable to the situation where the user B does not obtain the offline information through the client B but directly deletes the offline information.

In the above-mentioned embodiments 1 to 6, the IM servers to which the sending end and the receiving end belong are all different servers. The following takes the IM server to which the sending end and the receiving end belong are the same server as an example to describe the technical solution of the present invention in detail .

Embodiment seven

When the instant message and the successful delivery report in the first embodiment are sent between clients belonging to the same IM server, it constitutes the seventh embodiment of the present invention.

FIG. 9 is a flowchart of a method for sending an instant message report in Embodiment 7 of the present invention. In this embodiment, the servers of the sending end and the receiving end are both IM servers, and the client B of the receiving end is offline, but can receive offline messages after going online, and send a successful delivery report through the MSRP data channel. As shown in Figure 9, the method for sending an instant message report in this embodiment includes the following steps:

Step 901, client A sends a SIP INVITE message to establish an MSRP data channel with the IM server according to user A's request.

Step 902, client A sends an MSRP SEND message to the IM server through the MSRP channel.

Since client B is offline at this time, the MSRP SEND message sent by client A is an offline message.

Among them, the MSRP SEND message includes: Message-ID, Success-Report: yes; Failure-Report: yes and other message headers and sent messages.

Step 903, the IM server stores the offline message, and replies an MSRP 200 "OK" message to client A, indicating that the IM server has received the offline message.

Among them, the MSRP 200 "OK" message only means that the offline message has been received, and does not mean that the offline message has been successfully sent to client B as the destination client.

The IM server includes an online message storage unit and an offline message storage unit, and the offline messages in this embodiment are stored in the offline message storage unit. The online message storage unit and the offline message storage unit may constitute an IM server, or may be two servers respectively.

The operation process of step 904 to step 911 is the same as the operation process of step 306 to step 313 in the first embodiment, and the IM server B in the step 306 to step 313 in the first embodiment is replaced with an IM server.

Step 912, after the IM server finds that the MSRP data channel has been disconnected, it sends a SIP INVITE message to the client A to establish the MSRP data channel between the IM server and the client A.

Step 913, the IM server sends an MSRP REPORT message including a successful delivery report to client A through the MSRP data channel.

In step 914, client A sends an MSRP 200 "OK" message to the IM server, indicating that the MSRP REPORT message has been successfully received.

Step 915, disconnect the MSRP data channel for sending the message delivery report.

In this embodiment, the successful delivery report sent in step 909 and step 913 may also be sent through MSRP SEND message. At this time, it is necessary to use MESSAGE/CPIM content type (content-type) to encapsulate the content type of the successful delivery report: message/imdn+xml; Content-Disposition: notification, and use XML content to represent the relevant information of the successful delivery report, such as Information such as the Message-ID of the received message, report content, time, and a summary description of the received message.

In this embodiment, if the client is ready to send a successful delivery report, and the IM server B disconnects the MSRP data channel after sending the offline message, the client B can also choose to send the delivery success report with SIPMESSAGE, and use Content type to encapsulate the content type of the delivery report: message/imdn+xml; Content-Disposition: notification, and use XML content to represent the relevant information of the successful delivery report, such as the Message-ID of the received message, report content, time, received Information such as a summary description of the message. At this point, change step 909 to: client B, client A and the IM server send SIP INVITE messages to each other to establish an MSRP data channel, so as to send a successful delivery report.

The present embodiment sets up the MSRP data channel by the SIP INVITE message, also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, also can disconnect the MSRP channel by other messages.

In this embodiment, the successful delivery report may be sent to client A through the IM server, or an MSRP data channel between client B and client A may be established, and client B directly sends the successful delivery report to client A.

This embodiment realizes the sending of the successful delivery report, and is also applicable to the sending of other types of delivery reports and reading reports.

Embodiment eight

When the instant message and reading report in the fourth embodiment are sent between clients belonging to the same IM server, it constitutes the eighth embodiment of the present invention.

FIG. 10 is a flowchart of a method for sending an instant message report in Embodiment 8 of the present invention. In this embodiment, the servers belonging to the sending end and the receiving end are both IM servers, and the client B at the receiving end reads the message sent by the client A after the MSRP data channel is disconnected, and sends the reading report through the SIP/IP core network. As shown in Figure 10, the method for sending an instant message report in this embodiment includes the following steps:

Step 1001, user A wishes to send an instant message to user B. Since the message exceeds the limit of SIP messages or clients, it needs to be sent through the MSRP data channel. Client A sends a SIP INVITE message to establish an MSRP data channel with the IM server. Similarly, An MSRP data channel is established between the IM server and client B.

The limitation of the SIP message in this step is that the IM server cannot send SIP messages larger than 1K bytes, and the limitation of the client is that Client B cannot receive SIP messages larger than 2K bytes.

In steps 1002 to 1003, client A sends an MSRPSEND message to client B through the IM server, including message headers such as Message-ID, Disposition-Notification: read and the sent message.

In steps 1004 to 1005, client B responds to client A with an MSRP200 "OK" message through the IM server, indicating that the message has been received, but it does not mean that it has been successfully sent to the destination.

Step 1006, client B judges that the received message needs to send a reading report to client A as the sender according to the reading report request in the message header, and client B reports successful receipt of the message to client A through the MSRP data channel, And send a SIP BYE message through the IM server B to disconnect the MSRP data channel.

Wherein, the reason for disconnecting MSRP may be: client B waits for a period of time without sending a message, or waits for a certain period of time without a message sending request, and disconnects the MSRP data channel in order to save network resources.

Step 1007, when user B reads the received instant message through client B, client B judges that the message has a reading report request based on the information in the message header.

In steps 1008 to 1009, the client B finds that the MSRP data channel has been disconnected, so the client B sends a SIP MESSAGE message including the reading report to the IM server through the SIP/IP core network.

Among them, the content type of the reading report is encapsulated by the content type of MESSAGE/CPIM: message/imdn+xml; Content-Disposition: notification, and the content of XML is used to represent the relevant information of the reading report, such as the Message-ID of the received message , report content, time, summary description of the received message and other information.

Step 1010～step 1011, the IM server receives the message, recognizes that the SIP MESSAGE message including the reading report is sent to the client A through the message header, and forwards the SIP MESSAGE to the client A through the SIP/IP core network.

In steps 1012 to 1013, client A receives the reading report, and replies a SIP 200 "OK" message to the IM server through the SIP/IP core network, indicating that the SIP MESSAGE message has been received.

Steps 1014 to 1015, the IM server receives the message, recognizes that the SIP 200 "OK" message is sent to client B through the message header, and forwards the SIP 200 "OK" to client B through the SIP/IP core network.

In steps 1008 to 1015, each time a message is forwarded, the route-related information in the message header can be changed according to the message destination information in the SIPMESSAGE message or the message header of the SIP 200 "OK" message, and then forwarded .

The present embodiment sets up the MSRP data channel by the SIP INVITE message, also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, also can disconnect the MSRP channel by other messages.

In this embodiment, the reading report can also be sent through the MSRP data channel. At this time, the reading report can be sent through the IM server, or an MSRP data channel between the client B and the client A can be established, and the client B directly sends the reading report to the client A.

The method in this embodiment is applicable to reading reports after reading online messages, and also applicable to reading reports after reading offline messages. When the method of this embodiment is used to send a reading report after reading offline messages, the operation process of steps 1002 to 1004 can be replaced with the operation process of steps 904 to 910 in Embodiment 7, that is, the process for users to obtain offline messages .

Embodiment nine

When the instant message and delivery failure report in the fifth embodiment are sent between clients belonging to the same IM server, it constitutes the ninth embodiment of the present invention.

FIG. 11 is a flowchart of a method for sending an instant message report in Embodiment 9 of the present invention. In this embodiment, the servers belonging to the sending end and the receiving end are both IM servers, and the client B is in an offline state. After the timeout of storing offline messages, the IM server sends a delivery failure report through the MSRP data channel. As shown in Figure 11, the method for sending an instant message report in this embodiment includes the following steps:

In step 1101, the IM server saves the offline message of user B for a timeout, deletes the offline message, and finds that the message includes a failed delivery report request according to the information in the message header of the message.

Step 1102, the IM server finds that the MSRP data channel has been disconnected, so the IM server sends a SIP INVITE message to the client A to establish an MSRP data channel with the client A.

Step 1103, the IM server sends an MSRP REPORT message including a delivery failure report to client A.

Among them, the content type of the delivery report is encapsulated by the MESSAGE/CPIM content type: message/imdn+xml; Content-Disposition: notification, and the relevant information of the successful delivery report is represented by XML content, such as the Message- ID, report content, time, summary description of the received message and other information.

In this step, the reading report can also be sent through the MSRP REPORT message.

Step 1104, client A replies MSRP 200 "OK" message to the IM server, indicating that the MSRP REPORT message has been successfully received.

Step 1105, the IM server disconnects the MSRP data channel for sending the message delivery report.

The present embodiment sets up the MSRP data channel by the SIP INVITE message, also can set up the MSRP channel by other messages; The present embodiment disconnects the MSRP data channel by the SIP BYE message, also can disconnect the MSRP channel by other messages.

In this embodiment, the delivery failure report may be sent to client A through the IM server, or an MSRP data channel between client B and client A may be established, and client B directly sends the delivery failure report to client A.

The method for sending a delivery failure report in this embodiment is applicable to the case where the IM server deletes the timed-out offline information, and is also applicable to the situation where the user B does not obtain the offline information through the client B but directly deletes the offline information on the IM server.

In Embodiment 2, Embodiment 4 and Embodiment 8 of the present invention, the MSRP data channel can be disconnected before client B receives or reads offline messages, or after client B receives offline messages or reads offline messages. On, after the MSRP data channel is disconnected, the step of sending the instant message report can be changed to send through the SIP/IP core network.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
