Pyshical Layer (physical layer)：Physical layer is used for transmitting data in MTP protocol.There are three kinds of physical layers at present
It is available for MTP to use.They are USB, Internet protocol (Internet Protocol, IP) and bluetooth (Bluetooth, BT) respectively.
USB speed when being mainly characterized by transmitting file and synchronized multimedia file is fast, and can be charged with side working edge, and this is current uses
A kind of most modes；IP-based MTP (abbreviation MTP/IP) will be matched and discovering device by UPnP, and it is home network
Comparatively ideal transmission means in network；Bluetooth is that MTP/BT compares power saving, but is also a kind of most slow transmission side of speed simultaneously
Formula, using less.Therefore, the embodiment of the present invention is preferred to use USB modes.
Transport layer：In MTP, data transmission format follows picture transfer protocol (Picture Transfer
Protocol, PTP) (USB Still Image Class, description USB still image catch behavior).
Layer order：The various orders in MTP protocol are realized, the associated description in MTP Spec is for details, reference can be made to.
Using order-response mode, come work, (Initator sends commands to Responder processing, Responser to MTP
Feedback processing result), the main feature of this mode has：All MTP orders are in equipment in the way of Package (packet)
Transmitted at two ends.Before Initiator must be received after the result (being whether successfully also a time out) of a piece of news,
Lower a piece of news can be sent.
So that PC is opened a file by MTP as an example, Fig. 3 is a kind of MTP command process stream provided in an embodiment of the present invention
Journey schematic diagram, the MTP command process flows of acquiescence are：After mobile phone terminal MTP starts, the MtpServer in MtpServer.cpp::
Run () can constantly be read out " message that PC is sent " by read () from "/dev/mtp_usb ".Read () is being read
After the message come to PC, MtpServer can be given::HandleRequest () is handled.According to " PC is read in file
The ID of the message of appearance " does different processing, and conventional ID includes：
MTP_OPERATION_GET_DEVICE_INFO
MTP_OPERATION_OPEN_SESSION
MTP_OPERATION_CLOSE_SESSION
MTP_OPERATION_GET_STORAGE_IDS
MTP_OPERATION_GET_STORAGE_INFO
MTP_OPERATION_GET_NUM_OBJECTS
MTP_OPERATION_GET_OBJECT_HANDLES
MTP_OPERATION_GET_OBJECT_INFO
MTP_OPERATION_GET_OBJECT
In document flow is opened, the ID of the message of " PC reads file content " in Fig. 3 is MTP_OPERATION_
GET_OBJECT；Therefore, it can be handled by doGetObject (), and doGetObject () can be called
Database of getObjectFilePath (), getObjectFilePath () meeting from MediaProvider

Identified in MTP protocol by SessionID, it is the unsigned int of one 32, selected by PC and be transmitted to mobile phone.
(3) PC ends need to return to the corresponding StorageID of some drive by GetStorageIDs orders.In MTP,
StorageID is 32 unsigned ints, and each StorageID represents a logical DOS drives.PC ends can basis
No. StorageID of previous step, the information for going to obtain storage device is operated using GetStorageInfo, such as remaining storage is empty
Between, file system type and access rights etc..
(4) PC obtains the handle Object of the file and subdirectory under this drive by GetObjectHandles orders
(an Object Handle represents a file or catalogue to Handles.The value is generated by Responder and ensures uniqueness).
(5) fileinfo (such as filename and file size) is passed to hand by PC by SendObjectInfo orders
Machine.Mobile phone needs to check whether target directory has enough space and corresponding authority.If all gone well, PC will pass through
SendObject passes the data to mobile phone.Real written document is then Responder in mobile phone to device memory.
