Abstract
The invention aims at providing a method for realizing interconnection and information sharing of mobile phones by using UBS (Universal Serial Bus) cables, and overcoming the defect of inconvenience of interconnection and information sharing among the mobile phones in the prior art. The method comprises the following steps of: setting a mobile phone A to be a host; setting a mobile phone B to be a slave; then interconnecting the two mobile phones by the standard USB cable; starting up the USB OTG function after setting the mobile phone A to be the host; and sending a connection request command to the mobile phone B by the USB cables and setting up connection. The invention provides a method for realizing interconnection and information sharing among mobile phones without any wireless transmission equipment such as the Bluetooth and the like, uses USB OTG technology to interconnect two mobile phones by cables and achieves the functions of document sharing, memory sharing, even interconnection of games and the like. By applying the method, not only a new mobile phone experience way of a mobile phone user can be greatly expanded, simultaneously wireless communication modules with high price can be avoided from being used in the mobile phones and the cost of buying mobile phones by the user is reduced.
Description
Technical field
The present invention relates to a kind of method of using USB cable to realize mobile phone interconnecting information sharing, be applicable to mobile communication terminals such as mobile phone.
Background technology
Present most mobile phone all provides USB cable to be used for when interconnecting with PC synchronous transmission information simultaneously, and some high-grade mobile phone also provides as technology such as bluetooths simultaneously provides between mobile phone communication as functions such as swap files.But provide at present in the mobile phone of Radio Transmission Technologys such as bluetooth, there are two problems: 1, wireless transmission chip cost with respect to USB cable is higher, 2, use agreement such as FTP have been determined in the mobile phone of the radio function that ordinary supplier provides, Handset, HandFree etc. can't realize wireless transmission between the mobile phone of use different agreement.
(abbreviation of USB On-The-Go, Chinese implication is " plug and play " to USB OTG, is a kind of complementary agreement of USB2.0 standard.OTG is by revising the stitch definition and the interface profile of USB interface, needs according to manufacturer, the definition USB device is the different identity of master control, subordinate and dual role, to satisfy the connection between various equipment or mobile device and the needs of exchanges data), be to use suitable mature technique at present, use USB OTG technology, mobile phone can be connected USB peripheral hardware and directly use.As inserting USB flash disk on the mobile phone, the host side (Host end) that mobile phone can be used as the USB system directly with file transfer to USB flash disk.But still there is not a kind of scheme that can between mobile phone and mobile phone, use USB OTG technology at present.
Summary of the invention
The purpose of this invention is to provide a kind of method of using USB cable to realize mobile phone interconnecting information sharing, overcome in the prior art and realize interconnecting information sharing inconvenience or the too high defective of cost between the mobile phone and mobile phone.
To achieve these goals, the technical solution used in the present invention comprises the steps:
Step 1, mobile phone A are set to main frame, and mobile phone B is set to slave, then by two mobile phones of standard USB cable line interconnection;
After step 2, mobile phone A are set to main frame, start USB OTG function, according to the usb communication agreement, mobile phone A will send the connection request order to mobile phone B by USB cable, obtain the information of mobile phone B, and begin to attempt to connect;
Step 3, mobile phone B are received the connection request that mobile phone A sends, and respond the request of mobile phone A, and matching with mobile phone A connect;
After step 4, mobile phone B and mobile phone A establish a communications link, begin to share information communication.
Described mobile phone A and mobile phone B provide in man-machine interface (MMI) function that this mobile phone is main frame or slave are set.
The present invention provides a kind of method that realizes interconnecting information sharing between the mobile phone for the mobile phone that does not have radio transmission apparatus such as bluetooth, use USB OTG technology,, and reach file-sharing by two mobile phones of cable bond, storage is shared, even function such as the recreation that interconnects.In this way, not only can enlarge the new mobile phone of cellphone subscriber greatly and experience mode, can avoid in mobile phone, using the wireless communication module of high price simultaneously, reduce the cost that the user buys mobile phone.
Description of drawings
Fig. 1 is two mobile phone connection diagrams of the present invention.
Fig. 2 is a host side software flow pattern of the present invention.
Fig. 3 is a slave end software flow pattern of the present invention.
Embodiment
Specifically describe embodiments of the present invention below in conjunction with accompanying drawing.
The technical solution used in the present invention comprises the steps:
Step 1, as shown in Figure 1, mobile phone A and mobile phone B provide in man-machine interface (MMI) function that this mobile phone is main frame or slave are set, and mobile phone A is set to main frame, and mobile phone B is set to slave, then by two mobile phones of standard USB cable line interconnection.This MMI program provides radio box to select to allow USB enter main frame or slave mode for the user, when mobile phone is set to main frame or slave, starts the USBHost (main frame) or slave (slave) protocol software respectively, comprises corresponding bus driver.This protocol software and bus driver are all realized according to USB OTG standard.
Step 2, as shown in Figure 2 after mobile phone A is set to main frame, starts USB OTG function, and when mobile phone B is connected with mobile phone A by cable, according to the usb communication agreement, both sides' mobile phone will be set up the connection of master-slave equipment.After this mobile phone A is independent of the program of USB standard with startup, and mobile phone A will send the connection request order to mobile phone B by USB cable, obtain the information of mobile phone B, and begin to attempt to connect;
Step 3, as shown in Figure 3, the mobile phone B same program that is independent of the USB standard that starts this moment, mobile phone B is received the connection request that mobile phone A sends, and respond the request of mobile phone A, and matching with mobile phone A connects;
Step 4, as shown in Figures 2 and 3 after mobile phone B and mobile phone A establish a communications link, because this communication protocol of program that is independent of the USB standard is self-defined for mobile-phone manufacturers, can begin to share information communication.Content of Communication comprises: general file transfer, cell-phone number code book are duplicated etc.Also comprise two Memory Sharing between the mobile phone, utilize Camera to record a video, but the content of video recording is saved in the mobile phone B the inside as mobile phone A.
Claims (3)
1, a kind of method of using USB cable to realize mobile phone interconnecting information sharing is characterized in that, comprises the steps:
Step 1, mobile phone A are set to main frame, and mobile phone B is set to slave, then by two mobile phones of standard USB cable line interconnection;
After step 2, mobile phone A are set to main frame, start USB OTG function, according to the usb communication agreement, mobile phone A sends the connection request order by USB cable to mobile phone B, obtains the information of mobile phone B, and begins to attempt to connect;
Step 3, mobile phone B are received the connection request that mobile phone A sends, and respond the request of mobile phone A, and matching with mobile phone A connect;
After step 4, mobile phone B and mobile phone A establish a communications link, begin to share information communication.
2, use USB cable as claimed in claim 1 realizes the method for mobile phone interconnecting information sharing, it is characterized in that described mobile phone A and mobile phone B provide in man-machine interface the function that this mobile phone is main frame or slave is set.
