Wherein, the capability value of the first transmission extra buffer and the first reception extra buffer synchronously changes, and first The capability value for sending extra buffer and the first reception extra buffer is equal to the second default value and the second increment value sum, and the Two default values and the second increment value sum are more than or equal to the size of data to be transmitted bag.

When the first reading and writing data forwarding module 012 of mobile terminal 100 receives the application processor of external equipment 200 second During the data to be transmitted bag of 20 transmissions, the classification logotype in data to be transmitted bag is obtained, is determined according to acquired classification logotype The type of data to be transmitted bag.If determine that data to be transmitted bag is data to be forwarded bag according to classification logotype, the first reading and writing data Data to be transmitted bag is then transmitted to the first data forwarding client 011 by forwarding module 012.When the first data forwarding client 011 when receiving data to be transmitted bag, and data to be transmitted bag is cached to first and sent in extra buffer.When the first data turn Hair client 011, which successfully caches data to be transmitted bag to first, to be sent in extra buffer, the second data transmitting server 216 Received from second and data to be transmitted bag is extracted in extra buffer.

First, which sends extra buffer and first, receives the capability value of extra buffer equal to the second default value and the second increasing Big value sum, the second default value and the second increment value sum are more than or equal to the size of data to be transmitted bag.Specifically, can be When first data forwarding client 011 detects data transfer instruction first, call corresponding with the first transmission extra buffer Driving interface, increase first send the capability value of extra buffer.It should be noted that due to first receive extra buffer and First transmission extra buffer correspond to same physical address, therefore the first transmission extra buffer and first receives interim delay The capability value for rushing area synchronously changes, i.e., when the first data forwarding service end increase first sends the capability value of extra buffer When, the capability value of the first reception extra buffer also synchronously increases.In the present embodiment, first extra buffer and first is sent After the capability value increase for receiving extra buffer, it is changeless, will not changes again.

In embodiments of the present invention, in order to ensure the first data transmitting server 116 and the first data forwarding client 011 Between data to be transmitted bag can whole Successful transmissions, the second increment value and the second default value sum should be greater than or equal to The size for the maximum data to be transmitted bag that one data transmitting server 116 and the first data forwarding client 011 are transmitted.

Further, if determining that data to be transmitted bag is pending data bag according to classification logotype, the first reading and writing data turns Hair module 012 then performs operation corresponding with data to be transmitted bag, such as shows the signal intensity of external equipment 200, or display Electricity of external equipment 200 etc..

It should be noted that classification logotype is used for the type for distinguishing data to be transmitted bag.In the present embodiment, number to be transmitted According to bag type include two kinds, it is a kind of be need not be sent to the first data transmitting server 116, it is necessary to the first reading and writing data The pending data bag that forwarding module 012 is handled, another kind are to need to be sent to the first data transmitting server 116 to wait to turn Send out packet.Classification logotype can be set according to specific needs, such as when classification logotype is 00, show data to be transmitted bag to treat Processing data bag；When classification logotype is 01, it is data to be forwarded bag to show data to be transmitted bag.

Further, when the first data transmitting server 116 receives data to be transmitted bag, data to be transmitted bag is led to Cross the first blocking module 115, remote sim data access server114 and the first SIM card module agency 113 and be sent to UIM drivings 112, UIM driving 112 obtained according to data to be transmitted bag from entity user identification card 14 corresponding to data respond data to be transmitted Bag, met with a response packet, and response data packet is pressed into backtracking to external equipment 200.UIM drivings 112 are according to be transmitted Packet obtains corresponding data from entity user identification card 14 and responded in the data to be transmitted packet procedures, and UIM drivings 112 will not Directly interacted with the file storage module in entity user identification card 14, but the first COS into entity user identification card 14 (Chip Operating System, chip operating system) operating system sends data acquisition request, and then entity user identifies The COS operating systems of card 14 obtain data based on the data acquisition request in file storage module, then by the data of acquisition UIM drivings 112 are transmitted further to, to realize the response of data to be transmitted bag.

UIM driving 112 obtained according to data to be transmitted bag from virtual user identifying card 13 corresponding to data respond it is to be transmitted Packet, the principle for the packet that meets with a response and the original that data response data to be transmitted bag is obtained from entity user identification card 14 Reason is consistent, will not be repeated here.

The present embodiment between external equipment 200 and mobile terminal 100 by transmitting in data to be transmitted packet procedures, increase Each component (the second data transmitting server 216, the second data forwarding client in external equipment 200 and external equipment 200 021st, the second reading and writing data forwarding module 022, the first reading and writing data forwarding module 012, the first data transmitting server 116 and One data forwarding client 011) in extra buffer capability value, make the capability value of extra buffer in each component be more than or Person is equal to the size of data to be transmitted bag, avoids during external equipment 200 and mobile terminal 100 carry out data transmission, By the packet transmitted is excessive, the situation of packet bust this is caused to occur.

Further, by increasing the capability value of extra buffer in each component, the big slight of data to be transmitted bag is made In or equal to extra buffer capability value, realize and carry out data transmission process in mobile terminal 100 and external equipment 200 In, when the size of the data to be transmitted bag transmitted is more than the default value of extra buffer, it is not necessary to split data to be transmitted Bag, can directly transmit a complete data to be transmitted bag, data to be transmitted bag efficiency of transmission be improved, simultaneously as being not required to Data to be transmitted bag is split, therefore is avoided after data to be transmitted bag is split, split a certain data to be transmitted bag is lost Lose, or in data to be transmitted inclusion during, the situation for synthesizing failure occurs, and improves data to be transmitted bag transmission success Rate.

Further, the second embodiment of data transmission system is proposed.The second embodiment of data transmission system and first The difference of embodiment is：

Second data transmitting server 216 is additionally operable to calculate the size of data to be transmitted bag, and judges data to be transmitted bag Size whether be more than the first default value；If the size of data to be transmitted bag is more than the first default value, data to be transmitted is calculated Difference between the size of bag and the first default value, the first increment value is determined according to difference.

When the second data transmitting server 216 gets data to be transmitted bag, the second data transmitting server 216 calculates The size of data to be transmitted bag, and judge whether the size of data to be transmitted bag is more than the first default value.If data to be transmitted bag Size be more than the first default value, the second data transmitting server 216 then calculates the size and the first acquiescence of data to be transmitted bag Difference between value, the first increment value is determined according to the difference for calculating gained.Specifically, the first increment value can be with calculating gained Difference is equal, also greater than calculate gained difference, such as can by the first increment value be dimensioned to be more than one word of the difference Section.When it is determined that after the first increment value, the second data transmitting server 216 sends interim buffering according to the first increment value increase second The capability value in area so that the second capability value for sending extra buffer is equal to the first increment value and the first default value sum.Meanwhile Second data forwarding client 021 calls driving interface corresponding with the second reception extra buffer, is increased according to the first increment value Big second receives the capability value of extra buffer, so that second receives the capacity of extra buffer and the second transmission extra buffer The synchronous change of value.

Further, the detailed process of the second data transmitting server 216 calculating data to be transmitted bag size is：Parsing is treated Transmission packet, the packet header of data to be transmitted bag is obtained, the size of data to be transmitted bag is obtained from packet header.Wherein, it is to be transmitted Packet is TLV forms, and TLV forms are one kind of BER (Basic Encoding Rules, BER Basic Encoding Rules) codings, entirely Referred to as Type (type), Length (length), Value (value), T fields represent the type of data to be transmitted bag, and L field represents to treat The size of the length of transmission packet, i.e. packet, V fields are used for depositing the content of data to be transmitted bag.

If the size that the second data transmitting server 216 is additionally operable to data to be transmitted bag is less than or equal to the first acquiescence Value, data to be transmitted bag is cached to capability value and sent for the second of the first default value in extra buffer.

Second application processor 20 is additionally operable to receive in extra buffer for the second of the first default value from capability value and obtained Data to be transmitted bag, data to be transmitted bag is sent to the first reading and writing data forwarding module 012 by preset interface.

If the size of data to be transmitted bag is less than or equal to the first default value, the second data transmitting server 216 then changes Become the second capability value for sending extra buffer, directly cache data to be transmitted bag to second that capability value is the first default value Send in extra buffer.It is the first acquiescence when the second data transmitting server 216 caches data to be transmitted bag to capability value When the second of value sends extra buffer, the second data forwarding client 021 of the second application processor 20 from capability value be the The second of one default value, which receives, obtains data to be transmitted bag in extra buffer, acquired data to be transmitted bag is transmitted into the Two reading and writing data forwarding modules 022, data to be transmitted bag is sent to by shifting by USB by the second reading and writing data forwarding module 022 First reading and writing data forwarding module 012 of dynamic terminal 100.

When the first data forwarding service termination receives the data to be transmitted bag of the first reading and writing data forwarding module 012 transmission When, the first data forwarding client 011 can adjust first according to the size dynamic of data to be transmitted bag and send extra buffer Capability value, the first data forwarding client 011 adjust first according to the size dynamic of data to be transmitted bag and send extra buffer Capability value and the second data transmitting server 216 adjust second according to the size of data to be transmitted bag dynamic and send interim buffering The capability value process in area is similar, will not be repeated here.

Further, the second data transmitting server 216 is additionally operable to when the second application processor 20 receives temporarily from second When data to be transmitted bag is got in buffering area, reduce second and send the capability value of extra buffer to the first default value.

When the second data forwarding client 021 in the second application processor 20 is equal to the first default value and the from capability value When successfully getting data to be transmitted bag in the second reception extra buffer of one increment value sum, the second data transmitting server 216 call driving interface corresponding with the second transmission extra buffer, and the capability value of the second transmission extra buffer is decreased to First default value, i.e., the capability value of extra buffer is sent from equal to the first default value and the reduction of the first increment value sum by second To the first default value.The second data transmitting server 216 reduce second send extra buffer capability value to first acquiescence During value, the second data forwarding client 021 also calls driving interface corresponding with the second reception extra buffer, by second The capability value for receiving extra buffer is decreased to the first default value.

It should be noted that data to be transmitted bag has an end of identification, can be determined by the end of identification to be passed Whether transmission of data bag is successfully read.After the end of identification of data to be transmitted bag in the second reception extra buffer is read, Show that the second data forwarding service end successfully gets data to be transmitted bag.Because the second transmission extra buffer and second connects Receive extra buffer and correspond to same physical address, therefore the second data transmitting server 216 can be read according to end of identification Situation about taking determines that 021 whether successful received from second in extra buffer of the second data forwarding client gets number to be transmitted According to bag, so as to decide whether to perform the operation for reducing the capability value of the second transmission extra buffer to the first default value.

If it is understood that dynamically adjusted between the second data transmitting server 216 and the second data forwarding client 021 Whole second sends extra buffer and second receives the capability value of extra buffer, the second reading and writing data forwarding module 022 and the Dynamic can be used to adjust between one reading and writing data forwarding module 012, or using the second extra buffer of disposable adjustment and The capability value of first extra buffer, it can be used between the first data transmitting server 116 and the first data forwarding client 011 Dynamic adjusts, or sends extra buffer and first using disposable adjustment first and receive the capability value of extra buffer.By This understands that external equipment 200 and mobile terminal 100 are during carrying out data transmission, capacity between each extra buffer pair Being worth Adjusted Option can be consistent, also can be inconsistent.In embodiments of the present invention, there are three pairs of extra buffers pair, the respectively second hair Extra buffer and second is sent to receive extra buffer, the second extra buffer and the first extra buffer and the first transmission Extra buffer and first receives extra buffer.

Each extra buffer may be equal to corresponding default value, it is also possible to unequal.It is understood that when each When extra buffer is equal to corresponding default value, corresponding increment value is also equal；When each extra buffer is to corresponding silent Recognize value it is unequal when, corresponding increment value is also unequal.Therefore, if three extra buffers are to all using dynamic adjustment capability value Scheme, it is possible that one or both of which extra buffer is to needing to adjust capability value, and remaining interim buffering Area is to that need not adjust the situation of capability value.

In the present embodiment, the second extra buffer and the second default value for sending extra buffer may be equal, also may be used Can be unequal, therefore, in the present embodiment, data to be transmitted bag is sent by USB in the second reading and writing data forwarding module 022 During the first reading and writing data forwarding module 012, the second reading and writing data forwarding module 022 is needed again according to data to be transmitted Magnitude relationship between the size of bag and the second extra buffer capability value determines whether to increase the capacity of the second extra buffer Value.Second reading and writing data forwarding module 022 increases the capability value process and the second data transmitting server of the second extra buffer The process that 216 increases second send extra buffer is similar, will not be repeated here.

The present embodiment adjusts the capacity of extra buffer in each component by the size dynamic according to data to be transmitted bag Value, ensure to transmit in data to be transmitted packet procedures between external equipment 200 and mobile terminal 100, it is not necessary to number to be transmitted The operation bidirectional split according to bag, and ensure that the first reading and writing data forwarding module 012 and the second reading and writing data forwarding module The essence of data channel transparent transmission between 022, avoid secondary splitting and reorganizing in data transmission procedure and bring data to damage, keep away simultaneously The capability value for having exempted from extra buffer in each component is constantly in enlarging state, the problem of so as to cause spatial cache to waste.

Further, the 3rd embodiment of data transmission system is proposed.The 3rd embodiment of data transmission system and first The difference of embodiment is：

Second data transmitting server 216 is additionally operable to obtain when the second application processor 20 receives extra buffer from second During to data to be transmitted bag, the data to be transmitted bag cached in the second transmission extra buffer is deleted.

When the second application processor 20 successfully gets data to be transmitted bag from the second reception extra buffer, i.e., the The second data forwarding client 021 in two application processors 20 successfully gets to be transmitted from the second reception extra buffer During packet, instruction is deleted in the triggering of the second data transmitting server 216, and deleting second according to deletion instruction sends extra buffer In data to be transmitted bag, with save second send extra buffer spatial cache.It is understood that due to the second transmission Extra buffer and the second reception extra buffer correspond to same physical address, therefore, when the second data transmitting server When 216 deletions second send the data to be transmitted bag in extra buffer, second receives the data to be transmitted in extra buffer Bag can be also deleted.

It should be noted that treated when the first reading and writing data forwarding module 012 is successfully got from the first extra buffer During transmission packet, the second reading and writing data forwarding module 022 can delete the data to be transmitted bag cached in the second extra buffer. Second reading and writing data forwarding module 022 can delete the data to be transmitted bag cached in the second extra buffer and the second data forwarding The data to be transmitted packet procedures that server 216 deletes the second transmission extra buffer caching are similar, will not be repeated here.

Further, before the application processor 20 of second modem 21 and second transmits data, at the second application Reason device 20 needs to be initialized.Second application processor 20 initialization detailed process be：When the second application processor 20 from When resting state enters wake-up states, the second data forwarding client 021 of the second application processor 20 counts to corresponding second Request message is sent according to forwarding server 216, to ask the second data transmitting server 216 as the second data forwarding client The 021 user's mark of distribution one.It should be noted that in external equipment 200 and mobile terminal 100, the one of modem Individual server correspond to the multiple client of application processor.Turn when the second data transmitting server 216 receives the second data Send out client 021 send request message after, the second data transmitting server 216 according to the request message send user identify to Second data forwarding client 021.When the second data forwarding client 021 is successfully received user mark, the second data Client 021 is forwarded to send test data bag to the second data transmitting server 216, wherein, carried in the test data bag User identifies.When the second data transmitting server 216 is successfully received test data bag, given according to backtracking notification message Second data forwarding client 021.When the second data forwarding client 021 is successfully received notification message, show that second should Initialized successfully with processor 20.After the second application processor 20 initializes successfully, by the He of the second data forwarding client 021 The mark of identification field in second data transmitting server 216 is arranged to specific identifier, to show the second application processor 20 Initialize successfully.
