The method embodiments providing the transmission of a kind of multi-media SMS, the executive agent of the method is terminal.Wherein, terminal has the function sending multi-media SMS, as being provided with SIM (SubscriberIdentityModule, the client identification module) mobile phone etc. blocked.Terminal can be provided with processor, memorizer, transceiver, screen etc..Processor may be used for the process of transmitting multimedia short messages and processes, memorizer may be used for being stored in the process of transmitting multimedia short messages needs the data of storage, transceiver may be used for transmitting-receiving multi-media SMS and other message, screen is displayed for the content etc. of multi-media SMS, it is possible to be the screen of touch.In the present embodiment, for terminal for being provided with the mobile phone of SIM, multi-media SMS is picture message, carries out the detailed description of scheme, and other situation is similar with it, and the present embodiment is not repeated.
As it is shown in figure 1, the handling process of the method can comprise the following steps that
Step 101, based on the first MTU MTU, is transmitted packet and divides, be transmitted dividing the transmission packet obtained the first multi-media SMS.
Wherein, multi-media SMS at least includes the one in picture, video, audio frequency.
nullIn force，As shown in Figure 2，User desires to good friend B and shares a pictures，The terminal A being provided with SIM can be used to send picture to the terminal B being provided with SIM of good friend B，User can in terminal A，Click short message option icons，Triggering terminal A shows contact person's edit box and short message edit box，User can input the telephone number of good friend B in contact person's edit box，Or the name of good friend B (if in address list, storage has the name of good friend B and corresponding telephone number)，Then on the side of short message edit box，Click and add option，Triggering terminal display emoticon、Picture、Shooting picture、The options such as video，User can click picture option，The all pictures preserved in triggering terminal A display terminal A，User can click the picture wanting to send，This picture is added in the first multi-media SMS by triggering terminal，User can click transmission button，Triggering terminal A sets up APN (AccessPointName，Access point) MMS (MultimediaMessagingService of type，MMS) data cube computation，MTU is set to the first MTU MTU，Oneth MTU can be initial MTU，Then the data connection request of multi-media SMS is sent to proxy server，After proxy server receives connection request，Return to terminal A and confirm message.After terminal A receives confirmation message, send to receive to proxy server and successfully confirm message, terminal A sets up multi-media SMS data cube computation (set up the process that multimedia body note data is connected and be properly termed as TCP (TransmissionControlProtocol, transmission control protocol) three-way handshake) with proxy server.
After multi-media SMS data cube computation set up by terminal A and proxy server, the first multi-media SMS according to a MTU, can be divided the transmission packet that data volume is a MTU, then by ready-portioned transmission packet, sends to proxy server by terminal A.The telephone number of good friend B, while sending transmission packet, is sent to proxy server by terminal A.
Step 102, when the first transmission packet bust this of the first multi-media SMS being detected, reduces a MTU, obtains the 2nd MTU.
Wherein, the first transmission packet is the arbitrary transmission packet after the first multi-media SMS divides.
In force, terminal A start to proxy server send the first multi-media SMS time, start timing, if (preset by technical staff in preset duration, and store in the terminal) within, it is not received by the transmission success message of proxy server feedback, then determine the first transmission packet bust this of the first multi-media SMS, terminal A can the MTU regulation rule preset of acquiring technology personnel, and obtain the MTU prestored, then according to the MTU regulation rule preset, reduce a MTU, obtain the 2nd MTU.
Optionally, the method reducing MTU has multiple, below exemplary provide two ways:
Mode one: when the first transmission packet bust this of the first multi-media SMS being detected, a MTU is reduced to default value, obtains the 2nd MTU.
Wherein, default value can be empirical value, it is possible to is drawn according to test of many times by technical staff, and stores to terminal.Such as, for IPV4, default value can be 1380～1400 bytes, and for IPV6 (IntemetProtocolVersion6, IPv6), default value can be 1280 bytes.
In force, when terminal A receives the transmission failure notification of the first multi-media SMS that proxy server sends, may determine that the first multi-media SMS bust this, the default value prestored can be obtained, and obtain a MTU, then a MTU is reduced to default value, obtains the 2nd MTU, using the 2nd MTU as the MTU again transmitting the first multi-media SMS.Such as, for IPV4, oneth MTU can be initial MTU, can be 1500 bytes, default value is 1380～1400 bytes, when terminal A detects the first multi-media SMS bust this, terminal A can obtain default value 1380～1400 byte prestored, and then 1380～1400 bytes is defined as the 2nd MTU.
Mode two: when the first transmission packet bust this of the first multi-media SMS being detected, a MTU is reduced and presets adjusted value, obtain the 2nd MTU.
Wherein, preset adjusted value and arrange for technical staff, and store in the terminal, for instance, default adjusted value is 10 bytes, 50-20* (n-1) byte (n is the number of times retransmitted).
In force, when terminal A receives the transmission failure notification of the first multi-media SMS that proxy server sends, may determine that the first multi-media SMS bust this, terminal A can obtain the default adjusted value prestored, and obtain a MTU, then a MTU is reduced and preset adjusted value, obtain the 2nd MTU, using the 2nd MTU as the MTU again transmitting the first multi-media SMS.Such as, default adjusted value is 10 bytes, oneth MTU is initial MTU, it is 1500 bytes, when terminal A detects the first multi-media SMS bust this, terminal A can obtain the default adjusted value (10 byte) prestored, and obtains a MTU (1500 byte), then obtaining the 2nd MTU is 1490 bytes, using 1490 bytes as the MTU again transmitting the first multi-media SMS.
It addition, presetting adjusted value is 50-20* (n-1) byte, n attaches most importance to and newly transmits the number of times of the first multi-media SMS, and a MTU is 1500 bytes.When terminal A detects the first transmission packet bust this of the first multi-media SMS, terminal A can obtain the number of times again transmitting the first multi-media SMS, if second time is transmitted again, the default adjusted value then obtained is 30, the 2nd MTU obtained is 1470 bytes, using 1470 bytes as the MTU again transmitting the first multi-media SMS.
Optionally, technical staff is also provided with retransmitting the re-transmission interval of the first multi-media SMS, and the process of corresponding step 102 can be:
When reaching preset duration after the first transmission packet bust this first multi-media SMS being detected, reduce a MTU, obtain the 2nd MTU.
Wherein, preset duration can be preset by technical staff, and stores to terminal, such as 10 seconds.
In force, when terminal A receives the transmission failure notification of the first multi-media SMS that proxy server sends, may determine that the first multi-media SMS bust this, when determining preset duration after the first multi-media SMS bust this, the MTU regulation rule that terminal A can preset according to technical staff, reduce a MTU, obtain the 2nd MTU, using the 2nd MTU as the MTU again transmitting the first multi-media SMS.
Optionally, technical staff is also provided with the number of times that the first transmission packet is retransmitted, and the process of corresponding step 102 can be:
When the first transmission packet bust this first multi-media SMS being detected, and when the number of retransmissions of the first transmission packet reaches predetermined threshold value, reduce a MTU, obtain the 2nd MTU.
In force, when terminal A receives the first transmission packet transmission failure notification in the first multi-media SMS that proxy server sends, may determine that the first of the first multi-media SMS transmits packet bust this, terminal A can detect the first transmission data packet retransmission number of times, and obtain the predetermined threshold value prestored, if the first data packet retransmission number of times reaches predetermined threshold value, terminal A no longer transmits packet to first and retransmits, the MTU regulation rule that terminal A can preset according to technical staff, reduce a MTU, obtain the 2nd MTU, using the 2nd MTU as the MTU again transmitting the first multi-media SMS.
Optionally, technical staff is also provided with the number of retransmissions of the first multi-media SMS, and the process of corresponding step 102 can be:
When the first transmission packet bust this first multi-media SMS being detected, and when the first multi-media SMS reduces MTU the number of times that retransmits not up to predetermined threshold value, reduce a MTU, obtain the 2nd MTU.
In force, when terminal A receives the transmission failure notification of the first multi-media SMS that proxy server sends, may determine that the first multi-media SMS bust this, terminal A can detect the number of retransmissions of the first multi-media SMS, and obtain the predetermined threshold value prestored, if the number of retransmissions of the first multi-media SMS is not up to predetermined threshold value, the MTU regulation rule that terminal A can preset according to technical staff, reduce a MTU, obtain the 2nd MTU.Such as, terminal A get predetermined threshold value be 3 times, the first multi-media SMS retransmitted 1 time, a MTU can be reduced to default value by terminal A, obtains the 2nd MTU, and the 2nd MTU is default value.
Additionally, if as it is shown on figure 3, the number of retransmissions of the first multi-media SMS has reached predetermined threshold value, terminal A shows that in display interface the first multi-media SMS sends failed notification message, user can click and retry option, and triggering terminal A resends the first multi-media SMS.
Step 103, based on the 2nd MTU, re-starts transmission packet and divides, be transmitted repartitioning the transmission packet obtained the first multi-media SMS.
In force, after terminal determines the 2nd MTU, multi-media SMS data cube computation set up by terminal A and proxy server, and (connection procedure is shown in the concrete process in step 101, repeat no more) herein, terminal A can according to the 2nd MTU, first multi-media SMS is divided into the transmission packet that data volume is the 2nd MTU, then by ready-portioned transmission packet, sends to proxy server.
After proxy server receives ready-portioned transmission packet, ready-portioned transmission packet can be merged, obtain the first complete multi-media SMS, and obtaining the terminal A telephone number sent, the terminal B then installed to the SIM that telephone number is corresponding sends the reception notice receiving multi-media SMS.After terminal B receives the reception notice that proxy server sends, it is possible to obtain the MTU of oneself prestored, then send the data connection request of the multi-media SMS of the MTU carrying oneself to proxy server.After proxy server receives the terminal B data connection request sent, it is possible to carry out resolving the MTU that acquisition is wherein carried, then the MTU of oneself can be adjusted to the MTU less than or equal to terminal B, and proxy server sends to terminal B and confirms message.After terminal B receives the confirmation message that proxy server sends, it is possible to send reception to proxy server and successfully confirm message.Proxy server receive terminal B send reception successfully confirm message after,
Proxy server can according to the MTU after adjusting, first multi-media SMS is divided, obtain the transmission packet of the first multi-media SMS, then each transmission packet of the first multi-media SMS is sent to terminal B, terminal B will receive each transmission packet and be combined, obtain the first multi-media SMS, then display.
