IMDN is a kind of message disposition notification, comprises the processing notice of three types: delivery, processing, read, wherein whether the read notification type is used to indicate message receiver message-submission to be read to the user and by the user.The read notification type comprises three kinds of states " read " (reading), " forbidden " (forbidding), " error " (makeing mistakes).

When message sender need be to message receiver request IMDN; Just in the message of sending, comprise the Disposition-Notification header field; And in the Disposition-Notification header field, specify the notification type (for example one or more among read, forbidden, the error) want, thereby be that the Disposition-Notification header field of " read " comes the request message recipient to reply reading report through in message, comprising value.

In addition, message sender need also will comprise the Message-ID header field in the message of sending when message receiver request IMDN, and this header field comprises a globally unique message identifier.When message sender is received an IMDN, the value of the value of Message-ID and < message-id>element among the IMDN is compared, with the IMDN that confirms to receive to the issued message of which bar.

For example, user A comprises the header field value in the message of issuing user B asks user B answer reading report for the Disposition-Notification header field of " read ", and the Message-ID value of this message is 34jk324j; User B receives that this message rear line A replys IMDN; And with the value of < message-id>element among the IMDN of value of above-mentioned Message-ID as this answer; When user A receives this IMDN of user B answer; The value of < message-id>element is wherein mated with the Message-ID value of sending out message of local storage, learn Message-ID value be 34jk324j send out message by user B reading, so user A is updated to " reading " with this condition of information.

Foregoing description be the situation that a user has equipment to receive message and reply IMDN, can receive message when a user has at least two equipment, the message that application server just needs to send to this user sends on two equipment of this user at least.

In the message communicating under the multi-equipment environment, when message receiver has at least two equipment, the message that transmit leg is issued the recipient will be forwarded on two equipment of recipient at least.After at least two equipment of recipient were received same message, if the recipient has read this message on an equipment therein, then this condition of information also needed to be synchronously " reading " state on recipient's miscellaneous equipment.

The embodiment of the invention provides a kind of method that realizes state synchronized, can be used for the synchronous of application server realizing message status, specifically can comprise: after receiving the message of transmit leg transmission, comprise the message of reading report request to each equipment transmission of recipient; Receive the reading report of said recipient's equipment transmission; This equipment is to receive the equipment of reading this message at least in two equipment of the message that comprises said reading report request, and said reading report is to read the reading report that the equipment of this message sends according to the said reading report request in this message; (comprise the miscellaneous equipment outside the equipment that sends said reading report in recipient's the equipment to said recipient's equipment; Can also comprise the equipment that sends said reading report) send and to be used for synchronous reading report, notify said recipient's equipment to upgrade said condition of information according to this reading report.Recipient's reception after the equipment of said message receives the reading report of said message; The identifying information of the message that this reading report is corresponding and the local identifying information coupling that has received message; When finding corresponding message; Said condition of information is updated to reads, thereby the message that has realized at least two equipment of recipient " is read " state synchronization.

For ease of understanding, will combine accompanying drawing that the method flow of the embodiment of the invention is described in detail below to the embodiment of the invention.

Fig. 1 is the method flow sketch map of the embodiment of the invention, and is as shown in Figure 1, and corresponding idiographic flow can comprise:

11: application server is received the message that sends to the recipient, and this recipient has at least two equipment, after guaranteeing to comprise the reading report request in the said message, sends it to each equipment of recipient; For example; After application server receives that transmit leg sends to recipient's message; After judging that according to the header field value of this message this message of receiving is reading report, can check the reading report request that whether comprises message sender in this message, if do not comprise the reading report request of message sender; Send it to the recipient after then in this message, increasing the reading report request that is used for state synchronized, then directly this message is sent to the recipient if comprise the reading report request;

12: after each equipment of recipient was received the message that comprises the reading report request, the equipment of reading this message sent reading report and gives application server; Can comprise different value in the header field of said reading report is used to identify application server and whether need sends said reading report to transmit leg; For example: if comprise the reading report request of the transmit leg of this message in the message that receiver equipment is received, the device replied of then reading this message is provided with the reading report of the header field value of representing the answer transmit leg and gives application server; Perhaps; If comprise the reading report request of the transmit leg of message in the message; But the recipient reads when confirming not reply reading report after the said message through one of them equipment, and the equipment structure of reading this message is provided with the reading report of the header field value that is used for state synchronized and sends to application server; Perhaps; If do not comprise the reading report request of the transmit leg of message in the message; But comprise the reading report request that is used for state synchronized that application server increases, the equipment structure of then reading this message is provided with the reading report of the header field value that is used for state synchronized and sends to application server;

13: after application server receives that the recipient has read the reading report that the equipment of the message that comprises the reading report request sends; Reading report is sent to the miscellaneous equipment that the recipient has received said message, and the notice miscellaneous equipment upgrades corresponding condition of information based on this reading report; Application server can also be judged this reading report type based on the header field value of this reading report, and confirms to have received the miscellaneous equipment of said message except that reading report being sent to the recipient based on judged result, whether this reading report is sent to transmit leg; For example, concrete can comprising:

If comprised the header field value that is used to represent to reply transmit leg in this reading report, judge that then this reading report is the reading report of the equipment of said recipient's read messages based on the reading report request answer of the said transmit leg that comprises in this message; Then transmit this reading report to said transmit leg, and to said recipient's reception the miscellaneous equipment of this message send the reading report of this message;

If comprised the header field value that is used for state synchronized in this reading report; Judge that then this reading report is that the equipment of said recipient's read messages is because the recipient confirms not reply reading report based on the reading report request of the transmit leg that comprises in this message and the reading report that is used for state synchronized of structure; Perhaps this reading report is that said recipient reads the reading report request of the equipment of this message based on the application server increase; And the reading report that is used for state synchronized of structure then sends the reading report of this message to the miscellaneous equipment that said recipient has received this message.

After recipient's miscellaneous equipment is received the reading report of the said message that application server is transmitted; The identifying information of the message that reading report is corresponding and the local identifying information coupling that has received message; When finding corresponding said message; Said condition of information is updated to reads, thereby realized that message " is read " state synchronization at least two equipment of recipient.

Foregoing has been described application server at the method flow that carries out when synchronous; Can find out; The embodiment of the invention can use less information flow-rate to realize that the message between at least two equipment of recipient " reads " state synchronization; Can avoid because use data sync agreement is carried out a large amount of interacting messages in the synchronizing process, thus the burden of mitigation system.

Processing logic below in conjunction with application server in 2 pairs of embodiment of the invention of accompanying drawing is described in detail.

Fig. 2 is the processing logic sketch map of application server, and is as shown in Figure 2, and corresponding concrete processing logic can comprise:

201: after application server is received message, this message is checked;

202: application server judges that according to the header field value of this message this message is reading report; Because the reading report that the recipient sends also is a message, therefore, application server judges whether this message contains the Content-Disposition header field earlier; If contain the Content-Disposition header field, then carry out 203; If do not contain the Content-Disposition header field, then carry out 207;

203: inspection Content-Disposition header field value, and according to header field value judgement reading report type; The reading report type can comprise the reading report of transmit leg request and the reading report of state synchronized; For example in IMDN (instant message indication notice; Instant Message Disposition Notification) in the mechanism; If this message contains the Content-Disposition header field of header field value for " notification "; Think that then this message is the IMDN that message receiver is replied, i.e. reading report; " notification " header field value of Content-Disposition header field is expanded into " notification_sender " perhaps " notification_sync " in embodiments of the present invention; When therefore application server is judged type of message according to Content-Disposition header field value; If the header field value of this message is " notification_sender " perhaps " notification_sync "; Then this message is reading report, otherwise is not reading report; Wherein, The answer of the reading report that Content-Disposition header field value is asked message sender for the IMDN information representing recipient of " notification_sender ", Content-Disposition header field value be the reading report that the IMDN representative of " notification_sync " sent for the state synchronized needs; According to judged result, if the header field value of this message that application server is received then carries out 204 for " notification_sender "; If the header field value of this message that application server is received then carries out 206 for " notification_sync "; If other header field value then carries out 205;

204: if the header field value of this message that application server is received comprises " notification_sender "; Then this message is the reading report that the recipient replys transmit leg; So application server is transmitted to message sender with this reading report, and change the Content-Disposition header field value of reading report into " notification_sync "; And send to the miscellaneous equipment that the recipient receives corresponding message respectively, with the message of notice miscellaneous equipment read states synchronously;

205:, then directly transmit this message if the Content-Disposition header field value of this message is other value;

206: if the header field value of this message that application server is received comprises " notification_sync "; Then this message is for synchronously and the reading report that sends; So application server sends the reading report of this message respectively to the recipient's who has received corresponding message miscellaneous equipment, and can not transmit this reading report and give message sender;

207: judge whether comprise the Disposition-Notification header field in this message; If comprise the Disposition-Notification header field in this message, then carry out 208; If do not comprise the Disposition-Notification header field in this message, then carry out 211:

208: inspection Disposition-Notification header field value, judge whether this Disposition-Notification comprises " read "; If comprise " read ", then carry out 209; If do not comprise " read ", then carry out 210;

209: if the Disposition-Notification header field value of this message comprises " read "; Because the transmit leg of message is if will ask IMDN just need in message, comprise the Disposition-Notification header field to the recipient of message; In the Disposition-Notification header field, specify the type of the processing notice of wanting simultaneously; The Disposition-Notification header field value of the request reading report that has defined is " read ", and application server is transmitted this message to the recipient after receiving this message;

210: if the Disposition-Notification header field value of this message does not comprise " read "; Then need in this message, increase and be used for synchronous reading report request; Owing to message receiver need to discern the reading report of asking in the message of receiving be the message sender request or application server ask synchronously in order to realize recipient's message status; And can't realize this differentiation in the current mechanism; Therefore the embodiment of the invention is through expanding Disposition-Notification header field value; Increase " self-report " header field value; Represent that the application server under the multi-equipment environment asks reading report for message " reads " state synchronization, application server increases header field value " self-report " in the Disposition-Notification of this message header field after, send it to each equipment of recipient;

211: if this message does not comprise the Disposition-Notification header field; Then application server increases the Disposition-Notification header field in message; The header field value is " self-report "; And after in this message, increasing the Message-ID header field, this message is sent at least two equipment of recipient.

The foregoing description content introduction at least two equipment messages of application server realizing recipient processing logics when " reading " state synchronized; Can find out; The embodiment of the invention will have that " notification " header field value expands to " notification_sender " and " notification_sync " just can distinguish now: the answer of the reading report that message receiver is asked message sender, and the reading report that sends in order to need synchronously; And the embodiment of the invention is also through expanding Disposition-Notification header field value; Promptly this header field is increased " self-report " header field value; Represent that the application server under the multi-equipment environment asks reading report for message " reads " state synchronization; Thereby the reading report that makes each equipment of message receiver can discern the message request of receiving is the message sender request, or application server " is read " state synchronized and asked in order to realize recipient's message.

The embodiment of the invention also provides a kind of message treatment method, can be applied to comprise in the recipient system of a plurality of receiving equipments, specifically comprises: said a plurality of receiving equipments receive the message that comprises the reading report request that application server sends; At least one receiving equipment in said a plurality of receiving equipment sends reading report to application server after reading said message; Miscellaneous equipment in said a plurality of receiving equipment receives the reading report of the said message of said application server transmission, and upgrades the said condition of information that has received according to said reading report.

Concrete, if comprise the reading report request of the transmit leg of said message in the said message, read after the said message to send and be provided with the reading report that is used to represent reply the header field value of transmit leg to application server; Perhaps, if comprise the reading report request of the transmit leg of said message in the said message, but the recipient reads when confirming not reply reading report after the said message, and structure is provided with the reading report of the header field value that is used for state synchronized and sends to application server; Perhaps, if comprise application server in the said message for the reading report request that state synchronized increases, then read said message after, structure is provided with the reading report of the header field value that is used for state synchronized and sends to application server.
