Technical field

The present invention relates to communication technical field, relate in particular in the communication system between a plurality of equipment of recipient the message synchronous method and apparatus of read states.

Background technology

In the interacting message of communication system, the transmit leg of message can be by increasing request IMDN (instant message indication notice in the message that sends, Instant Message Disposition Notification), reply message sender IMDN after coming the request message recipient to receive message, with the processed situation of notification message transmit leg message.

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 that sends, 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 by in message, comprising value.

In addition, message sender need also will comprise the Message-ID header field in the message that sends when message receiver request IMDN, and this header field comprises a globally unique message identifier.When message sender is received an IMDN, with among the value of Message-ID and the IMDN＜message-id the value of element compares, with the IMDN that determines to receive at 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 among the IMDN of value as this answer with above-mentioned Message-ID＜message-id〉value of element, when user A receives this IMDN of user B answer, will be wherein＜message-id〉value and the Message-ID value of sending out message of local storage of element mate, learn that the Message-ID value read by user B for the message of sending out of 34jk324j, 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.

For example, user A sends message by equipment 1 to user B, core net is routed to this message the application server in territory, user B place, after this application server is checked this message header, obtain the services addresses of user B, learn that user B has two equipment can be used to receive this message behind the inquiry local data base,, will go into equipment 1 and the equipment 2 that message sends to user B respectively by core net so this application server is rewritten the destination address of this message.In this case, as user A during to user B request IMDN, if the equipment of user B has been read the message that user A sends, so on the miscellaneous equipment of user B this condition of information also to need be " reading " state synchronously.

At present, adopt the data sync agreement can be implemented in message status at least two equipment of a user synchronously.The data sync agreement is carried out synchronous flow process, comprises establishment of connection, carries out synchronously and finishes synchronously.

The inventor finds that there are the following problems at least in the prior art in realizing process of the present invention:

Application server and receiver equipment all must be supported the data synchronous protocol, if there is a side not support the data synchronous protocol, just can't realize message read states synchronous by this method; And adopt the data sync agreement to carry out needing to carry out a large amount of interacting messages in the process of state synchronized, and increase system burden, take Internet resources.

Embodiment

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 are received same message, if the recipient read this message on an equipment therein, then on recipient's miscellaneous equipment this condition of information also to need be " reading " state synchronously.

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 described 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 described reading report request, and described reading report is to read the reading report that the equipment of this message sends according to the described reading report request in this message; (comprise the miscellaneous equipment outside the equipment that sends described reading report in recipient's the equipment to described recipient's equipment, can also comprise the equipment that sends described reading report) send and to be used for synchronous reading report, notify described recipient's equipment to upgrade described condition of information according to this reading report.Recipient's reception after the equipment of described message receives the reading report of described message, identifying information and the local identifying information coupling that has received message with the message of this reading report correspondence, when finding corresponding message, described 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, be described in detail below in conjunction with the method flow of accompanying drawing to the embodiment of the invention to the embodiment of the invention.

Fig. 1 is the method flow schematic diagram of the embodiment of the invention, and as shown in Figure 1, 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 described 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 to application server; Whether can comprise different value in the header field of described reading report is used to identify application server and needs to send described 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 determining not reply reading report after the described message by 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 described message, and the notice miscellaneous equipment upgrades corresponding condition of information according to this reading report; Application server can also be judged this reading report type according to the header field value of this reading report, and determines to have received the miscellaneous equipment of described message except that reading report being sent to the recipient according to 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 described recipient's read messages according to the reading report request answer of the described transmit leg that comprises in this message; Then transmit this reading report to described transmit leg, and to described 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 described recipient's read messages is because the recipient determines not reply reading report according to 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 described recipient reads the reading report request of the equipment of this message according to the application server increase, and the reading report that is used for state synchronized of structure, then the miscellaneous equipment that has received this message to described recipient sends the reading report of this message.

After recipient's miscellaneous equipment is received the reading report of the described message that application server is transmitted, identifying information and the local identifying information coupling that has received message with the message of reading report correspondence, when finding corresponding described message, described 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, as can be seen, 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 schematic diagram of application server, and as shown in Figure 2, 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: check Content-Disposition header field value, and judge the reading report type according to the header field value; 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 in embodiments of the present invention and is " notification_sender " or " notification_sync "; 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 " or " notification_sync ", then this message is reading report, otherwise is not reading report; Wherein, Content-Disposition header field value represent the answer of the reading report that message receiver asks message sender for the IMDN of " notification_sender ", and Content-Disposition header field value be that the IMDN of " notification_sync " represents the reading report that send 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: check 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 comprise the Disposition-Notification header field in message 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 defined request reading report 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 by 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, as can be seen, 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 by 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: described a plurality of receiving equipments receive the message that comprises the reading report request that application server sends; At least one receiving equipment in described a plurality of receiving equipment sends reading report to application server after reading described message; Miscellaneous equipment in described a plurality of receiving equipment receives the reading report of the described message of described application server transmission, and upgrades the described condition of information that has received according to described reading report.

Concrete, if comprise the reading report request of the transmit leg of described message in the described message, read after the described 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 described message in the described message, but the recipient reads when determining not reply reading report after the described 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 described message for the reading report request that state synchronized increases, then read described 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.

The recipient system that comprises a plurality of receiving equipments below in conjunction with 3 pairs of embodiment of the invention of accompanying drawing can being used to of providing realizes that message " reads " method flow of state synchronized and will be described.

Fig. 3 is recipient's the method flow schematic diagram that can be used to have at least two equipment of the embodiment of the invention, and as shown in Figure 3, corresponding idiographic flow can comprise:

31: receive the message that comprises the reading report request that application server sends; Concrete: at least two equipment of recipient are received same the message that application server sends; This message can comprise the reading report request of message sender or the reading report request that is used for state synchronized that application server increases;

32: send reading report to application server after reading described message; Concrete, after an equipment at least two equipment of recipient is read described message, send reading report to application server; For example:

If comprise the reading report request of the transmit leg of described message in the described message, read after the described 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 described message in the described message, but the recipient reads when determining not reply reading report after the described 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 described message for the reading report request that state synchronized increases, then read described 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;

33: the recipient receives the miscellaneous equipment of described message, receive the reading report of the described message that application server sends, according to the header field value of described reading report judge that application server sends be reading report after, the described condition of information of this reading report correspondence is updated to reads; Concrete, the recipient receives that the miscellaneous equipment of described message receives the reading report of the described message of application server transmission, identifying information and the local identifying information coupling that has received message with the message of reading report correspondence, find corresponding described message, described condition of information is updated to reads.

Foregoing has been described the method flow when receiver equipment is realized state synchronized, as can be seen, 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 4 pairs of embodiment of the invention receiver equipments of accompanying drawing is described in detail.As shown in Figure 4, corresponding concrete processing logic can comprise:

401: at least two equipment of recipient are received the message that application server sends;

402: whether comprise the Content-Disposition header field in the described message of recipient's equipment inspection,, carry out 403 if comprise; If do not comprise, carry out 406;

403: check Content-Disposition header field value,, then carry out 404 if the header field value comprises " notification_sender "; If the header field value comprises " notification_sync ", then carry out 405;

404: if the header field value of the described message of receiving comprises " notification_sender ", then this is at the reading report that has initiated a message, receiver equipment is with the identifying information of described message and the identifying information of local transmitted message (for example Message-ID value) coupling, when finding corresponding described message, described condition of information is updated to reads, realize that message " reads " state synchronized;

405: if the header field value of the described message of receiving comprises " notification_sync ", then described message is the reading report that application server sends in order to realize message between two equipment " to read " state synchronized at least, receiver equipment is with the identifying information and local identifying information (for example Message-ID value) coupling that has received message of described message, when finding corresponding described message, described condition of information is updated to reads, realize that message " reads " state synchronized;

406: receiver equipment checks whether comprise the Disposition-Notification header field in the described message: if comprise, then carry out 407;

407:, then carry out 408 if the Disposition-Notification header field value of described message comprises " read "; If the Disposition-Notification header field value of described message comprises " self-report ", then carry out 411;

408: it is the message sender request that the Disposition-Notification header field value of described message comprises the reading report that " read " illustrate this message: if the recipient has read described message by an equipment among at least two equipment, and be willing to purpose transmit leg answer reading report, then carry out 409; If determine not reply reading report, then carry out 410 to transmit leg;

409: if the recipient has read described message by equipment, and determine to reply reading report to transmit leg, then construct reading report, the Content-Disposition header field value of this reading report is made as " notification_sender ", send it to message sender then;

410: if the recipient has read described message by equipment, but determine not reply reading report to transmit leg, then still construct reading report, and the Content-Disposition header field value of this reading report is made as " notification_sync ", send it to message sender (in fact this reading report can not arrive message sender) then;

411: if the Disposition-Notification header field value of described message comprises " self-report ", then the reading report request of described message is that application server is in order to realize that message " is read " state synchronization and initiated (transmit leg that is message is not asked reading report) between at least two equipment of recipient, after the recipient has read described message by equipment, construct reading report according to this reading report request that application server is initiated, and Content-Disposition header field value is made as " notification_sync ", then this reading report is sent to application server.

The foregoing description content introduction recipient's equipment realize that at least two equipment messages " read " processing logic of state synchronized, as can be seen, in the embodiment of the invention, after recipient's equipment is received message, earlier judge whether this message is reading report, if reading report then mates reading report according to Content-Disposition header field value, to realize synchronously; If not being reading report, this message then do not realize synchronously according to Disposition-Notification header field value and user's wish structure reading report.And, 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 by 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, thus the reading report message sender request that each equipment of message receiver can be discerned ask in the message of receiving or application server " read " state synchronized and ask in order to realize recipient's message.

Transmit leg equipment in the embodiment of the invention is after the header field value of receiving the application server transmission is the reading report of " notification_sender ", the value of the Message-ID element in this reading report and the Message-ID value of sending out message are mated, just can find the corresponding message of sending out, and correspondence sent out information updating for reading.

Need to prove, in the actual communication interaction process, a receiver equipment also can be a transmit leg equipment simultaneously, therefore, receiver equipment in the embodiment of the invention also has the function of transmit leg equipment, the header field value of promptly receiving the application server transmission is for behind the reading report of " notification_sender ", the value of the Message-ID element in this reading report and the Message-ID value of sending out message are mated, just can find the corresponding message of sending out, and correspondence sent out information updating for reading.Like this, receiver equipment in the embodiment of the invention (also being transmit leg equipment simultaneously) is after receiving that a stature thresholding is for the reading report of " notification_sender ", can judge and learn this reading message, only need in transmitted message, to search corresponding message then at transmitted message; Or receiving that a stature thresholding is for behind the reading report of " notification_sync ", can judge and learn that this reading message is at receiving message, only need then to search corresponding message in the message receiving, like this with regard to having removed from since do not know this reading report be at transmitted message or received message and at transmitted message with received searching of carrying out in the message, thereby reduced the workload of half.

For ease of understanding, be described in detail below in conjunction with the specific implementation of accompanying drawing to the embodiment of the invention to the embodiment of the invention.

Specific embodiment one

Among this embodiment, reply to transmit leg under the situation of reading report, realize that message " is read " state synchronization between at least two equipment of recipient at receiver equipment.

If comprised the reading report request in the message that message sender sends, for example comprised the Disposition-Notification header field of header field value in this message of Fa Songing for " read ", after having read this message on the equipment of recipient in a plurality of equipment that receive this message, this equipment is according to the reading report request structure reading report of transmit leg, and Content-Disposition header field value is made as " notification_sender ", send this reading report to message sender then.This reading report at first arrives the application server of message receiver (being the transmit leg of reading report), application server is checked the Content-Disposition header field of this reading report, find that the header field value comprises " notification_sender ", just know that this reading report is the reading report that message receiver is replied according to the reading report request of transmit leg, so this reading report is transmitted to message sender, then for the reception that makes message receiver the miscellaneous equipment of same message also this condition of information is " reading " synchronously, application server changes the Content-Disposition header field value " notification_sender " in this reading report into " notification_sync ", and sends to the miscellaneous equipment that the recipient has received same message respectively.

After message sender equipment is received reading report, check the Content-Disposition header field, find that the header field value comprises " notification_sync ", just will be somebody's turn to do with in the reading report＜message-id the value of the value of element and the Message-ID of transmitted message mates, just can find corresponding message, the condition of information of correspondence is updated to read then.
