For picture message, the detailed description of scheme is carried out, other situations are similar therewith, and the present embodiment is not repeated.
As shown in Figure 1, the process flow of this method may include following step:
Step 101, it is based on the first maximum transmission unit MTU, transmission data packet is carried out to the first multi-media SMS and is divided, it is right
Obtained transmission data packet is divided to be sent.
Wherein, one of picture, video, audio are included at least in multi-media SMS.
In an implementation, as shown in Fig. 2, user, which desires to good friend B, shares a picture, it can be used and SIM card is installed
Terminal A sends picture to the terminal B for being equipped with SIM card of good friend B, and user can click short message option figure in terminal A
Mark, triggering terminal A show contact person's edit box and short message edit box, and user can input good friend B in contact person's edit box
Telephone number or good friend B name (if be stored in address list good friend B name and corresponding telephone number), then
On the side of short message edit box, addition option is clicked, triggering terminal shows the choosings such as emoticon, picture, shooting picture, video
, user can click picture option, all pictures saved in triggering terminal A display terminal A, and user can click desired hair
The picture is added in the first multi-media SMS by the picture sent, triggering terminal, and user can click transmission key, triggering terminal
A establishes MMS (Multimedia Messaging Service, the more matchmakers of APN (Access Point Name, access point) type
Body short message service) data connection, setting the first maximum transmission unit MTU, the first MTU for MTU can be initial MTU, then
The data connection request that multi-media SMS is sent to proxy server, after proxy server receives connection request, is returned to terminal A
Return confirmation message.After terminal A receives confirmation message, successful confirmation message, terminal A and generation are transmitted and received to proxy server
Reason server establishes multi-media SMS data connection, and (process for establishing the connection of multimedia body note data is properly termed as TCP
(Transmission Control Protocol, transmission control protocol) three-way handshake).
After terminal A and proxy server establish multi-media SMS data connection, terminal A can be according to the first MTU, by first
Multi-media SMS divides the transmission data packet that data volume is the first MTU and is sent to agency then by ready-portioned transmission data packet
Server.The telephone number of good friend B is sent to proxy server while sending transmission data packet by terminal A.
Step 102, when detecting the first transmission data packet transmission failure of the first multi-media SMS, the first MTU is reduced,
Obtain the 2nd MTU.
Wherein, the first transmission data packet is any transmission data packet after the first multi-media SMS is divided.
In an implementation, when terminal A starts to send the first multi-media SMS to proxy server, start timing, if pre-
If being not received by the transmission success of proxy server feedback within duration (preset, and stored in the terminal by technical staff)
Message, it is determined that the first transmission data packet transmission failure of the first multi-media SMS, the available technical staff of terminal A are preset
MTU adjustment rule, and pre-stored first MTU is obtained, rule then is adjusted according to preset MTU, reduces the first MTU,
Obtain the 2nd MTU.
Optionally, there are many ways to reducing MTU, below exemplary provide two ways:
Mode one: when detecting the first transmission data packet transmission failure of the first multi-media SMS, the first MTU is reduced
To default value, the 2nd MTU is obtained.
Wherein, default value can be empirical value, can be obtained by technical staff according to test of many times, and store to end
In end.For example, default value can be 1380~1400 bytes, for IPV6 (Intemet Protocol for IPV4
Version 6, Internet Protocol Version 6), default value can be 1280 bytes.
In an implementation, when terminal A receives the transmission failure notification of the first multi-media SMS of proxy server transmission,
It can determine the transmission failure of the first multi-media SMS, available pre-stored default value, and obtain the first MTU, so
The first MTU is reduced to default value afterwards, obtains the 2nd MTU, using the 2nd MTU as transmitting the first multi-media SMS again
MTU.For example, the first MTU can be initial MTU for IPV4, it can be 1500 bytes, default value is 1380~1400 words
Section, when terminal A detects the transmission failure of the first multi-media SMS, the available pre-stored default value 1380 of terminal A
Then 1380~1400 bytes are determined as the 2nd MTU by~1400 bytes.
Mode two: when detecting the first transmission data packet transmission failure of the first multi-media SMS, the first MTU is reduced
Default adjusted value, obtains the 2nd MTU.
Wherein, adjusted value is preset as technical staff's setting, and is stored in the terminal, for example, default adjusted value is 10 words
Section, 50-20* (n-1) byte (n is the number retransmitted).
In an implementation, when terminal A receives the transmission failure notification of the first multi-media SMS of proxy server transmission,
It can determine the transmission failure of the first multi-media SMS, the available pre-stored default adjusted value of terminal A, and obtain first
Then first MTU is reduced default adjusted value, obtains the 2nd MTU by MTU, the 2nd MTU is short as the first multimedia is transmitted again
The MTU of letter.For example, default adjusted value is 10 bytes, it is 1500 bytes, when terminal A detects first that the first MTU, which is initial MTU,
When multi-media SMS transmission failure, the available pre-stored default adjusted value (10 byte) of terminal A, and obtain first
MTU (1500 byte), then obtaining the 2nd MTU is 1490 bytes, using 1490 bytes as transmitting the first multi-media SMS again
MTU.
In addition, default adjusted value is 50-20* (n-1) byte, n, which attaches most importance to, newly transmits the number of the first multi-media SMS, first
MTU is 1500 bytes.When terminal A detects the first transmission data packet transmission failure of the first multi-media SMS, terminal A can be with
The number for transmitting the first multi-media SMS again is obtained, if it is transmitting again for the second time, then the default adjusted value obtained is 30,
The 2nd obtained MTU is 1470 bytes, using 1470 bytes as the MTU for transmitting the first multi-media SMS again.
Optionally, technical staff is also provided with the re-transmission interval for retransmitting the first multi-media SMS, the place of corresponding step 102
Reason can be with are as follows:
When reaching preset duration after the first transmission data packet transmission failure for detecting the first multi-media SMS, the is reduced
One MTU obtains the 2nd MTU.
Wherein, preset duration can be preset by technical staff, and be stored into terminal, and such as 10 seconds.
In an implementation, when terminal A receives the transmission failure notification of the first multi-media SMS of proxy server transmission,
It can determine the transmission failure of the first multi-media SMS, after determining the transmission failure of the first multi-media SMS when preset duration, terminal A
Rule can be adjusted according to the preset MTU of technical staff, reduce the first MTU, obtain the 2nd MTU, using the 2nd MTU as passing again
The MTU of defeated first multi-media SMS.
Optionally, technical staff is also provided with the number that the first transmission data packet is retransmitted, the processing of corresponding step 102
It can be with are as follows:
When the first transmission data packet for detecting the first multi-media SMS transmits failure, and the re-transmission of the first transmission data packet
When number reaches preset threshold, the first MTU is reduced, the 2nd MTU is obtained.
In an implementation, when the first transmission data packet in the first multi-media SMS that terminal A receives proxy server transmission
When transmission failure notification, the first transmission data packet transmission failure of the first multi-media SMS can be determined, terminal A can detecte the
One transmission data packet retransmission number, and pre-stored preset threshold is obtained, if the first data packet retransmission number reaches pre-
If threshold value, terminal A no longer retransmits the first transmission data packet, and terminal A can be according to the preset MTU adjustment rule of technical staff
Then, the first MTU is reduced, the 2nd MTU is obtained, using the 2nd MTU as the MTU for transmitting the first multi-media SMS again.
Optionally, technical staff is also provided with the number of retransmissions of the first multi-media SMS, and the processing of corresponding step 102 can
With are as follows:
When the first transmission data packet transmission failure for detecting the first multi-media SMS, and the first multi-media SMS reduces
The MTU and number retransmitted is when being not up to preset threshold, reduces the first MTU, obtains the 2nd MTU.
In an implementation, when terminal A receives the transmission failure notification of the first multi-media SMS of proxy server transmission,
It can determine the transmission failure of the first multi-media SMS, terminal A can detecte the number of retransmissions of the first multi-media SMS, and obtain
Pre-stored preset threshold, if the number of retransmissions of the first multi-media SMS is not up to preset threshold, terminal A can be according to skill
The preset MTU adjustment rule of art personnel, reduces the first MTU, obtains the 2nd MTU.For example, it is 3 that terminal A, which gets preset threshold,
Secondary, the first multi-media SMS has retransmitted 1 time, and the first MTU can be reduced to default value by terminal A, obtains the 2nd MTU, the
Two MTU are default value.
In addition, as shown in figure 3, terminal A is being shown if the number of retransmissions of the first multi-media SMS has reached preset threshold
Show that the first multi-media SMS sends the notification message of failure in interface, user, which can click, retries option, and triggering terminal A is again
Send the first multi-media SMS.
Step 103, it is based on the 2nd MTU, transmission data packet is re-started to the first multi-media SMS and is divided, to repartitioning
Obtained transmission data packet is sent.
In an implementation, after terminal determines the 2nd MTU, terminal A and proxy server establish multi-media SMS data connection (even
Termination process is shown in the specific processing in step 101, and details are not described herein again), terminal A can be short by the first multimedia according to the 2nd MTU
Letter is divided into the transmission data packet that data volume is the 2nd MTU and is sent to agency service then by ready-portioned transmission data packet
Device.
After proxy server receives ready-portioned transmission data packet, ready-portioned transmission data packet can be closed
And complete first multi-media SMS is obtained, and obtain the telephone number of terminal A transmission, it is then corresponding to telephone number
The terminal B of SIM card installation transmits and receives the reception notice of multi-media SMS.Terminal B receives the reception of proxy server transmission
After notice, then oneself available pre-stored MTU sends the more matchmakers for carrying the MTU of oneself to proxy server
The data connection request of body short message.After proxy server receives the data connection request of terminal B transmission, parsing can be carried out and obtained
The MTU wherein carried is taken, then the MTU of oneself can be adjusted to the MTU less than or equal to terminal B, and proxy server
Confirmation message is sent to terminal B.After terminal B receives the confirmation message of proxy server transmission, it can be sent out to proxy server
It send and receives successful confirmation message.After proxy server receives the successful confirmation message of reception of terminal B transmission,
Proxy server can divide the first multi-media SMS, obtain the first multimedia according to MTU adjusted
Then each transmission data packet of first multi-media SMS is sent to terminal B by the transmission data packet of short message, terminal B will be received
Each transmission data packet is combined, and is obtained the first multi-media SMS, is then shown.
The embodiment of the invention also provides several situations that terminal A determines the first MTU, corresponding processing be can be such that
If there is currently the second multi-media SMSs to be retransmitted, the second multi-media SMS will be retransmitted
MTU be determined as the first MTU, if there is currently no other multi-media SMSs to be retransmitted, will it is preset just
Beginning MTU is determined as the first MTU；Alternatively,
If there is currently the second multi-media SMSs to be retransmitted, the second multi-media SMS will be retransmitted
MTU reduce default adjusted value, obtain the first MTU, if there is currently no other multi-media SMSs to be retransmitted,
Preset initial MTU is then determined as the first MTU.
Wherein, adjusted value is preset as technical staff's setting, and is stored in the terminal, for example, default adjusted value is 10 words
Section, 50-20* (n-1) byte (n is the number retransmitted).Initial MTU is technical staff's setting, and is stored in the terminal, example
It such as, can be 1500 bytes for IPV4, initial MTU.
In an implementation, terminal A can detecte when determining a MTU and currently whether there is the second multi-media SMS
It retransmits, is being retransmitted if there is the second multi-media SMS, then obtain terminal A and retransmit the second multi-media SMS
MTU, by retransmit the second multi-media SMS MTU be determined as the first MTU.If there is currently no the second multi-media SMSs
It is being retransmitted, is then obtaining pre-stored initial MTU, initial MTU is then determined as the first MTU.
Alternatively, terminal A, which when determining a MTU, can detecte, currently whether there is the second multi-media SMS again
It sends, is being retransmitted if there is the second multi-media SMS, then available terminal A retransmits the second multi-media SMS
MTU, and obtain the default adjusted value of storage, the MTU that then will retransmit the second multi-media SMS reduces default adjustment
Value, obtains the first MTU.If there is currently no the second multi-media SMSs to retransmit, obtain pre-stored initial
Then initial MTU is determined as the first MTU by MTU.
Optionally, terminal A determines that the processing of the first MTU can also be as follows:
If there is currently the multi-media SMS having built up transmission to connect, the multi-media SMS having built up is transmitted
The MTU of connection is determined as the first MTU, will be preset if there is currently no the multi-media SMS having built up transmission to connect
Initial MTU is determined as the first MTU.
In an implementation, terminal A is when determining a MTU, can send multi-media SMS time point according to last time, judge away from
Whether the duration that multi-media SMS was sent from last time is more than preset duration, and preset duration can be preset by technical staff, and be deposited
Storage in terminal A, if being less than preset duration apart from the duration that last time sends multi-media SMS, illustrates present terminal A and generation
Reason server, which exists, has built up multi-media SMS transmission connection, and terminal A can will have built up multi-media SMS transmission connection
MTU, be determined as the first MTU.If the duration for sending multi-media SMS apart from last time is more than preset duration, illustrate present terminal
A and proxy server are connected there is no multi-media SMS transmission is had built up, the available pre-stored initial MTU of terminal A,
Initial MTU is determined as the first MTU.
The embodiment of the invention also provides, during terminal A receives third multi-media SMS, the method for adjusting MTU, such as
