Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the application.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that some aspects of the application are consistent.
In order to complete understanding the application, refer to numerous concrete details in the following detailed description, but it should be appreciated by those skilled in the art that the application can realize without the need to these details.In other embodiments, be not described in detail known method, process, assembly and circuit, in order to avoid unnecessarily cause embodiment fuzzy.
In the first aspect of the application, at server side, provide a kind of intelligent terminal near field document transmission method.Fig. 1 is the schematic flow sheet of a kind of intelligent terminal near field document transmission method shown in the application one exemplary embodiment, and as shown in Figure 1, described method comprises:
In step S101, the postural change time that server reception transmit leg intelligent terminal and recipient's intelligent terminal send, postural change address and unique identification.
Wherein, intelligent terminal uses the postural change time during gravity sensing unit acquisition postural change carried, use postural change address during GPS unit acquisition postural change, the acquisition of postural change time and postural change address can be carried out when needing two intelligent terminals of transfer files open near field file transmitting functions and carry out postural change.Described postural change will can be moved with certain form while of two intelligent terminals and contact for user, also can be that two intelligent terminals are close, do not contact with the motion of certain form simultaneously, described motion is for enabling the motion of gravity sensing unit perception intelligent terminal postural change, with the postural change time enabling gravity sensing unit obtain two intelligent terminals, such as, two intelligent terminals are along same track reverse direction operation.Wherein, ultimate range close between two intelligent terminals can according to server in subsequent step carry out recipient's intelligent terminal and transmit leg intelligent terminal pairing time distance threshold determine, such as distance threshold is 6m, then can the distance of interval 5m between two intelligent terminals, but because two intelligent terminals are separated by far away, more be difficult to maintenance be synchronized with the movement, can strengthen the error of follow-up pairing, therefore preferably two intelligent terminals move with certain form and contact.Intelligent terminal uses the postural change time during gravity sensing unit acquisition postural change carried, because gravity sensing unit can obtain the acceleration of intelligent terminal in X, Y and Z-direction, during intelligent terminal generation postural change, acceleration at least one direction can change, and the time of record acceleration change can obtain the postural change time.
After needing two intelligent terminals of transfer files to open near field file transmitting function, the described postural change time can also be obtained by the gyro sensor in intelligent terminal.Described postural change for user by two intelligent terminals near and rotate, or two intelligent terminals are contacted and rotate, such as shake intelligent terminal, the rotation of gyro sensor perception intelligent terminal, record the time of rotation thus the postural change time can be obtained.Wherein, close between two intelligent terminals ultimate range can according to server in subsequent step carry out recipient's intelligent terminal and transmit leg intelligent terminal pairing time distance threshold determine.
Postural change address is the address that intelligent terminal corresponds to the postural change time, i.e. the address of intelligent terminal when there is postural change, and can be obtained by the GPS locating module of intelligent terminal, the postural change address obtained represents with coordinate usually.The unique identification of intelligent terminal, can be the MAC (MediaAccessControl of intelligent terminal, medium access control) address, or IMEI (InternationalMobileEquipmentIdentity, mobile device international identity code).After server receives postural change time that both sides' intelligent terminal sends, postural change address and unique identification, record and store postural change time of both sides' intelligent terminal, postural change address and unique identification.
In step s 102, judge whether described transmit leg intelligent terminal and described recipient's intelligent terminal match according to described postural change time, postural change address and unique identification.
Wherein, after server receives postural change time of transmit leg intelligent terminal and recipient's intelligent terminal, postural change address and unique identification, judge whether described transmit leg intelligent terminal and recipient's intelligent terminal match, namely confirm, when the secondary both sides' intelligent terminal carrying out postural change, can comprise:
(1) time difference of transmit leg intelligent terminal postural change time and recipient's intelligent terminal postural change time is calculated;
(2) distance of transmit leg intelligent terminal postural change address and recipient's intelligent terminal postural change address is calculated;
(3) judge whether described time difference is less than time threshold and whether described distance is less than distance threshold;
(4) if described time difference is less than time threshold and described distance is less than distance threshold, then successful matching, otherwise, match unsuccessfully.
Wherein, time threshold can according to intelligent terminal itself obtain the precision of postural change time and pairing need determine, the usual precision of the time value obtained by gravity sensing unit can reach below 1s, therefore described time threshold can be 1s, because the time of postural change is very short, the postural change of two intelligent terminals of time difference within 1s can be considered as being postural change occurs simultaneously.Distance threshold can according to GPS obtain the precision of intelligent terminal coordinate and pairing need determine, GPS positioning precision can reach 5m usually, concentrate among a small circle carry out postural change simultaneously owing to generally not having multiple intelligent terminal, therefore described distance threshold can be set to 10m, also can be set to the rational values such as 6m.
When described time difference is less than time threshold and described distance is less than distance threshold, transmit leg intelligent terminal and the successful matching of recipient's intelligent terminal, namely (be considered as simultaneously) within the close time and two intelligent terminals of (in the scope that distance threshold limits) generation postural change can match in close distance.If described time difference is greater than time threshold, or described distance is greater than distance threshold, then match failure, that is, the length if both sides' intelligent terminal postural change time is separated by, then be considered as non-concurrent generation postural change, if both sides' intelligent terminal postural change address is separated by far, be then considered as not being participate in when time both sides' intelligent terminal of generation postural change.The result of pairing, i.e. successful matching and match unsuccessfully, with the unique identification of the transmit leg intelligent terminal carrying out matching and the unique identification of recipient's intelligent terminal, and the postural change time of transmit leg intelligent terminal and recipient's intelligent terminal postural change time are corresponding, by server record, inquiry can be prepared against.
The postural change time that transmit leg intelligent terminal sends and self postural change address and unique identification corresponding, the postural change time that recipient's intelligent terminal sends and self postural change address and unique identification corresponding, after server receives postural change time that transmit leg intelligent terminal and recipient's intelligent terminal send, postural change address and unique identification, preserve the postural change time of both sides' transmission, postural change address and unique identification, and calculate described time difference and described distance.Described time difference corresponds to the unique identification of transmit leg intelligent terminal and the unique identification of recipient's intelligent terminal, can get the absolute value of the difference of the postural change time of transmit leg intelligent terminal and the postural change time of recipient's intelligent terminal.Time difference described in described Distance geometry is corresponding, correspondingly also the unique identification of transmit leg intelligent terminal and the unique identification of recipient's intelligent terminal corresponding.When judged result is successful matching, determine by the unique identification of the transmit leg intelligent terminal corresponding with described time difference or distance the transmit leg intelligent terminal carrying out postural change, determine by the unique identification of recipient's intelligent terminal corresponding with described time difference or distance the recipient's intelligent terminal carrying out postural change.Namely transmit leg intelligent terminal and the recipient's intelligent terminal of determining to carry out postural change determine two intelligent terminals carrying out file transfer.
In step s 103, when described transmit leg intelligent terminal and described recipient's intelligent terminal successful matching, receive the file that described transmit leg intelligent terminal sends, and store described file.
Wherein, when described transmit leg intelligent terminal and the successful matching of recipient's intelligent terminal, in a kind of possible execution mode, server sends successful matching notice to transmit leg intelligent terminal, wherein, for two intelligent terminal whichever of carrying out postural change be transmit leg, whichever is recipient, can be distinguished when file opening transfer function by two intelligent terminals, namely the sending function in the transmission of transmit leg intelligent terminal file opening, the receiving function in the transmission of recipient's intelligent terminal file opening.Sending function and receiving function have different Function Identifications, be sent to server by transmit leg intelligent terminal and recipient's intelligent terminal corresponding with the unique identification of transmit leg intelligent terminal and the unique identification of recipient's intelligent terminal respectively, thus server can be distinguished, and whichever is transmit leg, whichever is recipient.
In the execution mode that another kind is possible, successful matching notice also can be issued both sides' intelligent terminal of successful matching simultaneously by server, after transmit leg intelligent terminal for reception to described successful matching notice, the file that need transmit is sent to server, server receives described file, although recipient's intelligent terminal also receives successful matching notice, do not carry out action, thus server does not need, and differentiation whichever is transmit leg, whichever is recipient.In another execution mode, the query interface provided by transmit leg intelligent terminal polling server, by the pairing result of described query interface querying server, when inquiring the successful matching result corresponding with self unique identification, check described successful matching result corresponding by the transmit leg postural change time of server record and the postural change time of transmit leg intelligent terminal self record, if two postural change times are equal, then represent when time both sides' intelligent terminal successful matching of generation postural change, transmit leg intelligent terminal sends the file that need transmit to server, server receives described file.The for the benefit of repeated downloads of file, the described file that server stores receives.
In step S104, generate the download address of described file.
Wherein, after server receives described file, generate the download address of described file, download address is stored in server after generating, and is beneficial to the repeated downloads of file.After server generates the download address of described file, recipient's intelligent terminal can download described file according to described download address, completes file transfer.
