Abstract
The invention discloses a mobile phone interconnection method based on an OTG technique. The method comprises following specific steps of directly connecting a USB interface of a mobile phone A and a USB interface of a mobile phone B through an OTG cable; if one mobile phone receives a USB ID interruption signal transmitted by the cable, starting an OTG mode of the mobile phone as USB Host; operating the other mobile phone in a USB Device mode by default, and starting handshake by the two mobile phones; carrying out handshake communication by the mobile phone A and the mobile phone B; and after the handshake is successful, selecting a file at the mobile phone A or the mobile phone B side by a mobile phone owner, thus sharing the file in a USB mode. According to the method, the existing problems of inconvenience in transferring the mobile phone file by using a transferring medium, and the instability and rate by using wireless interconnection are solved.
Description
Technical field
The invention belongs to OTG technical field, specifically a kind of mobile phone interconnecting method based on OTG technology.
Background technology
Current people's day by day promoting according to patience mobile phone, a lot of people not only have and use a mobile phone, are frequently encountered the situation needing the staged files to arrive another mobile phone, or share some videos, picture, file etc. with colleague friend.
For this situation, substantially solution can be classified as two kinds at present: carrys out the staged files by transfer medium, such as computer, USB flash disk etc.；By bluetooth, the wireless technology such as WiFi realizes interconnection and directly transmits.The medium such as computer or USB flash disk the first carried out to the mode of the staged files by transfer medium, it is clear that ageing not strong, because can not be had whenever and wherever possible available；The mode that the second is wireless interconnected, there is also some shortcomings, such as transfer rate relys more on the tenability of mobile phone, for cell phone platform comparatively high-end in the market, such as the MSM8974 platform of high pass, supporting WiFi chip transfer rate theoretical upper values just arrives 300Mbps, and wireless transmission method and apart from closely bound up, also being easily disturbed, transfer rate is discounted certainly.
Summary of the invention
There is disadvantages mentioned above or deficiency for prior art, the invention provides a kind of mobile phone interconnecting method based on OTG technology, solve to currently use the inconvenience of transfer medium transfer mobile phone file, and use wireless interconnected unstability and problem rate.
For achieving the above object, the technical scheme is that a kind of mobile phone interconnecting method based on OTG technology specifically comprises the following steps that
S1. the USB interface of mobile phone A and the USB interface of mobile phone B are directly connected to by OTG cable；
S2. as mobile phone A receives the USBID interrupt signal of cable transmission, then starting OTG pattern is USBHost；
S3. mobile phone A is USBHost pattern, then mobile phone B acquiescence operates in USBDevice pattern, and two handset startings are shaken hands；
S4. mobile phone A and mobile phone B handshake communication；
S5. shaking hands after successfully, mobile phone owner selects file to share in USB mode in mobile phone A or mobile phone B end.
Further, if mobile phone B receives the USBID interrupt signal of cable transmission in step s 2, then mobile phone B being set to USBhost pattern, mobile phone A will for USBDevice pattern, and two mobile phones can share file after shaking hands.
Further, above-mentioned middle OTG cable, including MicroUSB, MiniUSB etc., other merge class or customization class interface, and USBID foot is cable one end ground connection.
Further, mobile phone can automatically switch between USB master slave mode.
As further, file transfer rate can reach the speed of 480Mbps.
Due to the fact that the above technical scheme of employing, following technique effect can be obtained: based on OTG technology, not only achieving two mobile phones need not by transfer medium direct interconnection, the radio interconnected unstability brought of customer service and the low problem of transfer rate again, make two mobile phones can be more convenient, mutually share file faster.
Accompanying drawing explanation
The present invention has accompanying drawing 3 width:
Fig. 1 is two mobile phone interconnecting schematic diagrams of the present invention；
Fig. 2 is the OTG cable inner schematic diagram used in embodiment；
Fig. 3 is FB(flow block) of the present invention.
Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, technical scheme is described in further detail.
Embodiment 1
In following description, OTG cable is exemplified as the cable of MicroUSB interface type the most general at present；
S1. as it is shown in figure 1, mobile phone A and mobile phone B are connected on the OTG cable two ends of MicroUSB interface respectively；
S2. as in figure 2 it is shown, due on the interface of OTG cable wherein one end USBID pin and ground be connected together, so when mobile phone A or mobile phone B are connected on this end, can be all one the low interruption of generation of corresponding mobile phone；
S3. according to usb protocol, when USBID pin receives low interruption, corresponding mobile phone will be placed in USBhost pattern；
S4. when receiving the USBID mobile phone interrupted and being placed in USBhost pattern, the DC voltage of one about 5V of internal generation is just gone up to the USB power source line of OTG cable, the mobile phone being so connected on the other end receives this 5V signal, will start USB portion circuit, and be placed in USBdevice pattern；
S5. when two mobile phones are respectively disposed in USBhost and USBdevice pattern, meeting handshake communication, namely successfully establish data channel after successfully wait shaking hands；
S6., after data channel is successfully established, mobile phone owner can select respective file at mobile phone A end or mobile phone B end and select to share in USB mode.
OTG cable includes the cable of various interface, and such as MicroUSB, MiniUSB etc., other merge class or customization class interface, and USBID foot is cable one end ground connection.Mobile phone interconnecting thinking based on OTG technology, although supporting that the mobile phone of OTG is very many currently on the market, but OTG cable compares generic USB line on the one hand is distinguishing, people often neglect this function, people are often due to online etc. are accustomed on the other hand, the wireless mode utilization rates such as WiFi are caused to be greatly promoted, therefore the wireless way for transmitting file such as WiFi more accustomed to using, but when needs transmit large data files, just clearly, and the media such as computer can not be carried with for the instability of the wireless modes such as WiFi and the slow weakness of speed.
Use OTG cable to realize mobile phone direct interconnection by the USB interface of two mobile phones, the inconvenience that transfer medium passes mutually can be avoided the need for；OTG technology is the extension to usb protocol so that mobile phone can automatically switch between USB master slave mode, even transfer rate 2.0 also can reach the speed of 480Mbps, and highly stable, and the impact of interference-free and distance etc..
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope of present disclosure; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
