Standby OS Type establishes interface channel with the terminal device, includes the following steps：
2022, the bridging device determines the iTunes protocol versions of the terminal device.
It should be understood that when terminal device is IOS system equipments, since different IOS system versions are different, iTunes associations
View version would also vary from, and the protocol header for the data packet transmitted in different iTunes protocol versions also can be different, therefore, lead to
This step is crossed, first determines the iTunes protocol versions of terminal device.
2023, the bridging device sends handshake packet according to the iTunes protocol versions to the terminal device, so that
The terminal device feedback response message；
2024, determine whether to receive the response message, if thening follow the steps 2025；
2025, the bridging device, which is sent, determines that message establishes the interface channel to the terminal device.
It should be noted that when not receiving above-mentioned response message in preset duration, bridging device can be sent again
Above-mentioned handshake packet, specific preset duration can be configured according to practical situations, not limited here.Illustratively, in advance
If duration can be 10,20,5ms etc..
That is, bridging device can obtain iTunes protocol versions, TH_SYN is sent according to iTunes protocol versions
Handshake packet gives IOS system equipments, waits for the response of IOS system equipments, if returning to IOS system equipments returns to TH_RST, indicates IOS systems
Equipment of uniting refusal connection；If IOS system equipments return to TH_ACK, bridging device sends TH_ACK and confirms that packet is set to IOS systems
Standby, interface channel is successfully established at this time.
203, bridging device determines whether that fittings equipment is inserted into, if so, thening follow the steps 204.
Bridging device is also provided with other for the interface being connect with fittings equipment, such as audio interface, video interface, USB
Interface etc., does not limit specifically herein, can be configured according to the product form of practical bridging device.In the embodiment of the present invention
In, bridging device can determine whether that fittings equipment is inserted into real time, if thening follow the steps 204.
204, bridging device enumerates fittings equipment.
In embodiments of the present invention, bridging device can enumerate fittings equipment, and in other words, bridging device can detect more
A fittings equipment.In practical applications, terminal device user may have access to all fittings equipments that bridging device is enumerated.
It should be noted that above-mentioned steps 203- steps 204 have no time order and function relationship with abovementioned steps 201-202, have
Body does not limit herein.
205, terminal device is communicated by the interface channel with the fittings equipment.
After bridging device and terminal device establish above-mentioned interface channel, terminal device can by above-mentioned interface channel with
The fittings equipment is communicated.Illustratively, terminal device user can be by showing that screen selection communicates
Fittings equipment communicated；Illustratively, the embodiment of the present invention also provide with the mating application program of bridging device (APP),
The APP is mounted in the terminal device, and terminal device, can be by above-mentioned after establishing above-mentioned interface channel with bridging device
All fittings equipments of bridging device are inserted into APP displayings, and user can select some fittings equipment to lead to by APP at this time
Letter.
It should be noted that in embodiments of the present invention, for the terminal device of different operating system type, the also company of offer
Connect the optimal way in road.
It is described after the bridging device establishes the interface channel with the terminal device for Android system equipment
Method further includes：
In the bridging device to before the terminal device transmission data, the bridging device splits data to be transmitted
For N number of target data packet, wherein the data to be transmitted is 512*M bytes, and the N and M are positive integer, and the M is more than or waits
In 1, the N is greater than or equal to 2, at least one target data packet is less than 512 bytes in N number of target data packet；
The bridging device starts to send N number of target data packet in SOF to the terminal device in same a frame.
Illustratively, if bridging device will send 512Byte data and give android system equipment, bridging device can be with
The form that 512Byte is split as to 511Byte+1Byte is sent, and completes to send in the same SOF, not only not shadow
The transmission data for ringing data, also efficiently reduces the compatibility issue of different android system equipment USB ZLP.
It is illustrative again, give android system equipment as bridging device will send 1024Byte data, bridging device can be with
The form for being split into 512Byte+511Byte+1Byte is sent by 1024Byte, and completes hair in the same SOF
It send, likewise, not influencing the transmission data of data not only in this way, also efficiently reduces different android system equipment USB ZLP
Compatibility issue.
For IOS system equipments, after the bridging device establishes the interface channel with the terminal device, the bridge
It connects equipment and Window Size is fixed as preset value, wherein the preset value is not zero, and the preset value is more than the terminal
The default window size of equipment.
Illustratively, it is assumed that the default window size of terminal device is 258K, general bridging device Windows Size's
Default window size is 128K, and son promotes most 258K and remains unchanged through the embodiment of the present invention, avoids Windows Size
It is 0, occurs stopping equal situation, to improve IOS system equipment data transmission speeds.
For IOS system equipments, after the bridging device establishes the interface channel with the terminal device, the method
Further include：
When the bridging device and the terminal device are carried out data transmission using the interface channel, in a SOF
Interior at least one terminal device of reception feeds back symbol (ACK) of reading really.
It should be understood that since iTunes protocols are based on Transmission Control Protocol, in embodiments of the present invention, root in communication process
Different transmitting and receiving strategies is used according to Window Size, ACK, Sequence Number (serial number).The present invention is implemented can be with
Multiple USB Short Package (being generally less than 512Byte) are received in a SOF.So this method can be received quickly
Multiple continuous ACK packets improve bridging device end data transmission speed.
Illustratively, IOS system equipments in part, which often receive a data packet all, can return a corresponding ACK packet.If bridge
9 data packets can be received by meeting each SOF of equipment, and bridging device often sends 9 data packets, and IOS system equipments will return 9
If ACK packets can harvest 9 ACK packets using the method for the invention in a SOF；If not using implementation of the present invention
Example, then need 9 SOF times, therefore the embodiment of the present invention can save 8 SOF times, be effectively improved message transmission rate.
In conclusion compared with the existing technology, it can be to avoid the data wirelessly under radio connection, being transmitted
Rate and stabilization can with bandwidth, the influence of the factors such as environmental disturbances, meanwhile, the channel that bridging device using the present invention is provided
Bridging method can provide the interface channel that fittings equipment is directly connected to terminal device, can using interface channel fittings equipment
