In the present embodiment, it is necessary to data in explanation, virtual user identifying card 11A or entity user identification card 14 Bag is stored in file storage module, when the first modem 11 will obtain virtual user identifying card 11A or entity user knowledge Ka be in 14 packet when, the first modem 11 will not be recognized directly with virtual user identifying card 11A or entity user File storage module interaction in card 14, but the first COS into virtual user identifying card 11A or entity user identification card 14 It is Request that (Chip Operating System, chip operating system) operating system, which sends packet and obtains request, then The COS operating systems of virtual user identifying card 11A or entity user identification card 14 are based on the Request in file storage module Packet is obtained, the packet of acquisition is then transmitted further to the first modem 11, as long as the first modem 11 connects The packet of COS operating systems feedback is received, follow-up first application processor 10 obtains number in the first modem 11 The acquisition process of packet can be achieved according to bag.

It is appreciated that because the first modem 11 can not be in virtual user identifying card 11A or entity user identification card File storage module in 14 directly extracts packet, thus by with virtual user identifying card 11A or entity user identification card 14 COS operating systems are interacted, to realize the extraction of packet, it is ensured that follow-up data transmission procedure is normally run.

When the first application processor 10 extracts packet from virtual user identifying card 11A or entity user identification card 14 After the corresponding packet of acquisition request, then the packet of extraction is split, in the present embodiment, the first application processing The mode that device 10 is split to packet, is chosen as：Packet is parsed, to obtain the corresponding data of packet, so Data are decomposed according to preset capacity value afterwards, data are split into the data segment of multiple preset capacity values, then will Each data segment after fractionation carries out package operation, to obtain each subdata bag.Wherein, the preset capacity value may be configured as 512 bytes, in other embodiments, may be alternatively provided as other values, as long as ensureing that the capability value of each follow-up subdata bag is less than 512 bytes, are not limited herein.

First application processor 10 is split to packet with after obtaining each subdata bag, you can packet is torn open Point after each subdata bag addition identical identification information, most at last added with identification information each subdata bag cache to In USB buffer, so that the second application processor 20 extracts each subdata bag from the buffer, and according to identical Identification information carries out the combination of subdata bag, to complete the transmission of packet.

It should be noted that buffer is present in the two ends difference of the two ends of USB interface, i.e. USB interface in the present embodiment It is provided with buffer1 and buffer2.The is sent to when packet is obtained request by USB interface by the second application processor 20 During one application processor 10, the first application processor 10 is by the first modem 11 from virtual user identifying card 11A or reality Body Subscriber Identity Module 14 is extracted after packet, is first stored the packet of extraction into buffer1, to pass through USB transmission Into buffer2, the second application processor 20 obtains packet from buffer2 again.

The data packet transmission system that the present embodiment is proposed, the first application processor is received at the second application by preset interface When managing the packet acquisition request that device is sent, first the packet is extracted from the first Subscriber Identity Module or entity user identification card The corresponding packet of request is obtained, then the packet of extraction is split, and to each after the fractionation of same packet Subdata bag adds identical identification information, then each subdata bag added with identification information is cached to the preset interface Buffer in, so that the second application processor extracts each subdata bag from the buffer, and identified according to identical Information carries out the combination of subdata bag, to complete the transmission of packet.This programme is in transmission packet, first to number waiting for transmission Split, then will be transmitted after each subdata bag addition identical identification information after fractionation according to bag so that transmission The capability value of packet has reduced, and follow-up opposite end is weighed after receiving each subdata bag according to identical identification information Group, it is to avoid the situation that mobile terminal crashes in data transmission procedure.
