Detailed description of the invention
With reference to figure 1, exemplary embodiments comprises the mobile communication system of mobile communication terminal 110,120 and MMSC 130.Mobile communication terminal 110,120 and MMSC 130 transmit information and data by application layer protocol.In this exemplary embodiments, application layer protocol is MM1.MM1 is the 7th application layer protocol that is used for carrying out between application program by network information exchange.MM1 is defined as the interface between mobile communication terminal and the MMSC by 3GPP (third generation partnership project).
With reference to figure 2, in exemplary embodiments, mobile communication system transmits MMS information, and wherein the data allocations of MMS information is in protocol Data Unit (PDUs).In this exemplary embodiments, PDUs sequentially is transferred to MMSC 130.By being that each protocol Data Unit (PDU) increases trace information field as shown in table 1, MMSC 130 can discern the content of MMS information and the sequence instruction of PDUs.
Table 1.
| Information field | Value |
| Field name | ????<X-Mms-packet-value> |
| Field value | ????<Packet-count-value> |
| Explanation | ????<Optional> |
Like this, by the content of analytical information field, detect the sequence instruction of a plurality of PDUs.When in the MMS message transmitting procedure, producing mistake, detect and produce wrong PDU, continue the transmission again of MMS information from detected PDU.
Field value (for example,＜Packet-count-value 〉) is represented the sequence number of each PDU.The field value that is added to a PDU can be zero.In alternative embodiment, can not distribute field value.Like this, in one example, according to such as 0,1,2,3 ... one group of sequence number send PDUs.In an exemplary embodiments, first field value is that zero PDU is a PDU.In another example, if PDUs according to them such as 1,2,3 ... sequence number send, do not have apportioning cost to be relevant to first field.In one embodiment, a PDU comprises header field, and this header field comprises the information of the relevant information content and size.
When transmission ends 110 (for example, Tx end 110) transmission the one PDU (PDU1), message transmission begins, and it comprises to MMSC 130 request of sending (S202).MMSC 130 receives PDU1 and determines the content and the whole numbers of PDUs of information in the transmission information with reference to the header field of PDU1.MMSC 130 is by determining that with reference to information field separately the PDU that receives is a PDUs.
In one embodiment, MMSC 130 inspection message fields and will confirm that the acknowledge signal (ACK) that MMSC 130 has transmitted information and successfully received PDU sends to transmission ends 110 (S204).Comprise information field among the ACK.Therefore, receive terminal or the MMSC of ACK, receive the successfully number of the PDUs of transmission.
Refer again to Fig. 2, when MMSC 130 receives last PDU, it just with the MMS message transmission that receives to receiving terminal 120.In one embodiment, MMSC 130 will comprise the transmission request, and the PDU1 that just sends request is transferred to receiving terminal 120 (S220).As mentioned above, can not having field value or field value according to situation about carrying out PDU1 is 0 to be a PDU in the PDUs sequence that is included in the MMS information with expression PDU1.
Receiving terminal 120 (for example, Rx end 120) receives the information content and determines PDUs number in this information by the header field of reference PDU1.Receiving terminal 120 inspection message fields and send receipt signals (ACK) to MMSC 130 thus confirm the PDU transmission of Information and normal receive (S222).
With reference to figure 3, begin in order to represent message transmission, transmission ends 110 comprises the PDU1 (S302) of transmission request (just sending request) to MMSC 130 transmission.MMSC 130 determines the number (information size just) of the information content and PDUs by the header field of reference PDU1.MMSC 130 determines from information field whether the PDU that receives is first PDU.
In a preferred embodiment, MMSC 130 produce comprise the error message value (for example,＜Error-message-sending-count or＜X-Mms-packet-value) response message.MMSC130 does not transmit corresponding to the ACK of PDU3 but sets up the field name zone, and to transmission ends 110 transmission response information (S312).Transmission ends 110 is from the generation of error message value identification error, and temporarily stops the transmission of PDU.
In one embodiment, transmission ends 110 which PDU of identification have produced mistake, determine between transmission ends (for example terminal 110) and receiving terminal (for example MMSC 130) cause or a plurality of cause of one or more mistakes of producing, and in a cause or a plurality of cause (S314) of the one or more mistakes of application protocol layer correction.If can not correct mistakes immediately (for example network error), transmission ends 110 stops the MMS transmission of Information, and notice user profile is transmitted the reason that has stopped and why having stopped.
If revised the cause of wrong generation, which PDU is the error message value of transmission ends 110 from be included in response message determine has caused mistake.Transmission ends 110 is from for example PDU3 recovering information transmission (S316), and reception is from the ACK (S318) of MMSC 130.If PDUs and ACK subsequently transmit successively, as mentioned above, do not produce mistake, then successfully transmit PDU and ACK subsequently.
In order to begin the message transmission between MMSC 130 and the receiving terminal 120, MMSC 130 comprises the PDU1 (S330) of transmission request to receiving terminal 120 transmission.Receive the header field awareness information content and the PDUs number that comprise whole piece information of the receiving terminal 120 of PDU1 by reference PDU1.Receiving terminal 120 determines by the reference information field whether the PDU that receives is first PDU.Terminal 120 is determined information fields, and the receipt signal (ACK) that sends terminals 120 confirmation transmission and successfully received PDU to MMSC 130 (S332).
MMSC 130 receives ACK and transmits PDU2 (S334).If receiving terminal 120 does not successfully receive the PDU2 as challenge switch, network error or similar problem will appear in transmission course so.In this case, receiving terminal 120 is set up response message field name zone, and it contains such as＜Error-message-sending-count〉or＜X-Mms-packet-value the error message value.The error message value of this replacement ACK responds the 3rd PDU and is transferred to MMSC 130 (S336).MMSC 130 identification error information, and temporarily stop the transmission of PDU.
Therefore, MMSC 130 which PDU of identification have produced mistake, find out between transmission ends 110 and the receiving terminal (for example MMSC 130) cause or a plurality of cause of the one or more mistakes that produce, and in a cause or a plurality of cause (S338) of the one or more mistakes of application protocol layer correction.If can not correct mistakes immediately, such as owing to be network error, MMSC 130 stops the MMS transmission of Information, and has stopped and the reason of Stop message transmission to the user notification message transmission.
If revised wrong cause, which PDU MMSC 130 by stopping at reference to the error message value inspection transmission that is included in the response message, the transmission that recovery begins with the 2nd PDU, this transmission comprise that transmission recovers and receives ACK (S342) from MMSC 130.
In one embodiment, MMSC 130 receives ACK and transmits PDU3 (S344).MMSC 130 waits for up to receiving ACK (S346) from receiving terminal 120.If the transmission of PDU and ACK does not subsequently produce mistake, PDUs and ACK subsequently successfully transmit.
With reference to figure 4, when the MMS message transmission was set for the first time, transmission ends was divided into the PDUs (S410) of a plurality of MM1 agreements with MMS information, and preferably transmits a plurality of PDUs (S420) with consecutive order.
When having sent PDU, transmission ends is just checked the response message (S430) from receiving terminal, and has determined whether to send the response message (S440) that the reception of expression PDU has been finished.
If send the still uncompleted response message of reception of expression PDU, transmission ends will stop the transmission of PDU, find out the cause of the mistake that produces between transmission ends and the receiving terminal, and revise these wrong causes (S450), and the transmission that begins to recover PDU from the PDU of last transmission.
If send the response message that the reception of expression PDU has been finished, transmission ends will determine whether the transmission of each PDU finishes (S470).If transmission is not finished as yet, can carry out once more with the step of continuous sequential delivery PDUs, and repeating step (S420-S470).When having finished the transmission of PDUs, finish the MMS message transmission and discharge wireless connections (S480).
As previously discussed, the present invention is transmitted MMS information by dividing and transmitting PDUs automatically again in the MMS message transmitting procedure.Transmit, the at last PDU of transmission wrong again, owing to whole piece information needn't be transmitted again so Radio Resource is used more effectively from producing.
Among the present invention, the mistake that produces in the message transmitting procedure obtains revising in application layer, and finishes the transmission again of information automatically, therefore not only can but also can and revise the mistake that produces from low layer inspection more from equivalent layer.
