It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Fig. 1 shows a flow chart of an embodiment of a method for data transmission between mobile terminals according to the present invention.
In this embodiment, both the transmitting terminal and the receiving terminal are provided with touch screens. For convenience of description, the touch screen of the transmitting terminal may be referred to as a first touch screen, and the touch screen of the receiving terminal may be referred to as a second touch screen.
In the present embodiment, a mobile phone is taken as an example for detailed description. However, the method of the present invention is not limited to the application to the mobile phone, and may be applied to any mobile terminal having a communication function.
In step S11, in response to the user performing the continuous pointing operation on the first touch screen and the second touch screen, first pointing information of the first touch screen and second pointing information of the second touch screen are obtained, and identification information of the transmitting terminal and identification information of the receiving terminal are obtained.
The continuous finger-stroke operation is continuous finger sliding and is composed of a finger-stroke part on the first touch screen and a finger-stroke part on the second touch screen. For example, the user can make a finger slide on the first touch screen in an obliquely upward direction, and after the user slides out of the first touch screen, the user can continue to make the finger slide on the second touch screen in the same direction, so that a complete continuous finger-stroke operation is formed.
In step S12, the first and second designation information and the identification information of the transmitting terminal and the receiving terminal are transmitted to the server, respectively.
In step S13, the server distinguishes the mobile terminals according to the identification information, and performs matching verification on the sending terminal and the receiving terminal according to the first and second designation information.
In step S14, when the matching is successful, data transmission is performed between the transmitting terminal and the receiving terminal.
By adopting the method, the matching verification is carried out on the sending terminal and the receiving terminal according to the first finger information and the second finger information, and the matching relation can be quickly and accurately established for the sending terminal and the receiving terminal. By using the method, a hardware communication device is not required to be added, the influence of hardware types and transmission standards is avoided, and the problem of hardware compatibility is effectively solved.
Fig. 2 shows a flow diagram of one embodiment of matching verification of a transmitting terminal and a receiving terminal based on finger print information.
In this embodiment, the scribe information may include scribe trajectory information.
In step S131, a slip-out angle of the continuous finger stroke operation on the first touch screen and a slip-in angle on the second touch screen are determined according to the finger stroke trajectory information.
The fitting direction tracks of the finger stroke tracks on the first touch screen and the second touch screen can be performed by adopting a least square method, and the sliding-out angle on the first touch screen and the sliding-in angle on the second touch screen are calculated.
In step S132, it is determined whether the calculated slip-out angle on the first touch screen and the calculated slip-in angle on the second touch screen are close.
Specifically, an angle threshold may be set, and the difference between the slip-out angle and the slip-in angle may be compared to the angle threshold. When the difference is smaller than the angle threshold, determining that the slip-out angle on the first touch screen is close to the slip-in angle on the second touch screen, and executing step S133; when the difference is not smaller than the angle threshold, it indicates that the sliding-out angle on the first touch screen is not close to the sliding-in angle on the second touch screen, and step S134 is executed, that is, the two terminals do not establish a matching relationship.
It should be noted that, the slide-out angle and the slide-in angle for acquiring the finger-stroked trajectory need to take into consideration the screen sizes of the two mobile terminals, the relative positions during operation, and other factors. In a simplified example, in the case that the two mobile terminal screen edge lines are parallel or approximately parallel, tests show that within the range of the included angle of sliding out of about 90 degrees, 5 sliding out directions and sliding in directions can be distinguished easily. The included angle between two adjacent sliding-out directions is 18 degrees. Therefore, the angle threshold may be set to 9 degrees.
It should be understood by those skilled in the art that the specific value of the angle threshold may be adjusted according to the screen size of the mobile terminal, the relative position during operation, and other factors.
In step S133, it is determined that the transmitting terminal and the receiving terminal are successfully matched.
Fig. 3 shows a flow diagram of another embodiment of matching verification of a transmitting terminal and a receiving terminal based on finger print information.
In this embodiment, the finger stroke information may include finger stroke time information and finger stroke track information.
In step S231, the total time of the continuous finger stroke operation is determined according to the finger stroke time information.
Specifically, the swipe time information may include a slide-in time of the swipe operation on the first touch screen, a slide-out time on the first touch screen, a slide-in time on the second touch screen, and a slide-out time on the second touch screen.
In this way, the total time of the continuous finger-stroke operation can be calculated according to the slide-in time on the first touch screen and the slide-out time on the second touch screen.
Preferably, a Network Time Protocol (NTP) may be used, so as to ensure Time synchronization of terminals of different networks such as C, G, W. After measurement and calculation, the testing precision can reach 50ms after time synchronization is carried out by adopting a network time protocol.
In step S232, it is determined whether the total time of the continuous finger stroke operation is within the finger stroke operation time range.
In one embodiment, the set finger stroke operation time range may be 50ms to 500 ms.
When the judgment result is yes, step S233 is executed; when the determination result is no, step S236 is executed, that is, after the preliminary determination, the two mobile terminals are unsuccessfully matched.
In step S233, a slide-out angle of the continuous finger stroke operation on the first touch screen and a slide-in angle on the second touch screen are determined based on the finger stroke trajectory information.
In step S234, it is determined whether the calculated slip-out angle on the first touch screen and the calculated slip-in angle on the second touch screen are close.
Specifically, an angle threshold may be set, and the difference between the slip-out angle and the slip-in angle may be compared to the angle threshold.
When the difference between the slip-out angle and the slip-in angle is smaller than the angle threshold, step S235 is executed, that is, it is determined that the transmitting terminal and the receiving terminal are successfully matched; when the difference between the slip-out angle and the slip-in angle is not less than the angle threshold, step S236 is executed, that is, it is determined that the transmitting terminal and the receiving terminal fail to be matched.
Steps S233, S234, and S235 in this embodiment may be the same as steps S131, S132, and S133 shown in fig. 2, respectively, and are not described herein again.
Preliminary matching judgment is carried out according to the finger stroke time information, and unmatched sending terminals and receiving terminals can be filtered more quickly, so that final matching is more accurate.
Fig. 4 shows a flow chart of another embodiment of a method for data transmission between mobile terminals according to the present invention.
In step S31, in response to the user performing the continuous pointing operation on the first touch screen and the second touch screen, first pointing information of the first touch screen and second pointing information of the second touch screen, position information and identification information of the transmitting terminal and the receiving terminal are obtained. Wherein, the finger-stroke information may include finger-stroke time information and finger-stroke track information.
In step S32, the first and second designation information, the position information of the transmitting terminal and the receiving terminal, and the identification information are transmitted to the server, respectively.
The identification information is used for distinguishing and determining each mobile terminal. In step S33, it is determined whether the transmitting terminal and the receiving terminal are matched based on the location information of the mobile terminal.
The location information may include an international mobile subscriber identity of the terminal, IP information, and base station information.
For the case that the transmitting terminal and the receiving terminal belong to the same operator, the preliminary judgment of the position matching can be performed according to the position information.
Specifically, when the IP of the sending terminal and the IP of the receiving terminal are in the same network segment, it is preliminarily determined that the sending terminal and the receiving terminal are successfully matched, and step S34 is executed; when the IP of the sending terminal and the IP of the receiving terminal are in different network segments, it is determined that the sending terminal and the receiving terminal are unsuccessfully matched, and step S37 is executed, and a data transmission channel cannot be established between the two terminals.
The position information of the mobile terminal is utilized to judge the preliminary matching, so that a screening process is added, unmatched receiving terminals can be filtered more quickly, and matched sending terminals and receiving terminals can be determined efficiently and accurately.
In step S34, it is determined whether the transmitting terminal and the receiving terminal are matched based on the finger-cut time information.
Specifically, the total time of the continuous finger-stroke operation can be determined according to the finger-stroke time information; and judging whether the total time of the continuous finger-stroke operation is within the finger-stroke operation time range. When the judgment result is yes, step S35 is executed; if the result of the determination is negative, it indicates that the matching between the two terminals has failed, and step S37 is executed.
This step may be the same as steps S231 and S232 in the previous embodiment, and is not described herein again.
In step S35, it is determined whether the transmitting terminal and the receiving terminal are matched based on the finger trace information.
Specifically, according to the finger stroke track information, the sliding-out angle of the continuous finger stroke operation on the first touch screen and the sliding-in angle of the continuous finger stroke operation on the second touch screen are determined. Then, whether the calculated slide-out angle on the first touch screen is close to the slide-in angle on the second touch screen is judged.
When the difference between the slip-out angle and the slip-in angle is smaller than the angle threshold, performing step S36; when the difference between the slip-out angle and the slip-in angle is not less than the angle threshold, step S37 is performed.
This step may be the same as step S233 and step S234 in the previous embodiment, and is not described herein again.
In step S36, a data transmission channel is established between the transmitting terminal and the receiving terminal.
The method is convenient and easy to learn, the user operation is convenient, the method can be completed without training, and the user experience is effectively improved.
Fig. 5 shows a flow chart of yet another embodiment of a method for data transmission between mobile terminals according to the present invention.
In step S41, in response to the user performing the continuous pointing operation on the first touch screen and the second touch screen, first pointing information of the first touch screen, second pointing information of the second touch screen, position information and identification information of the transmitting terminal and the receiving terminal are obtained. Wherein, the finger-stroke information may include finger-stroke time information and finger-stroke track information. The identification information is used to distinguish the mobile terminals.
In step S42, the first and second designation information, the position information of the transmitting terminal and the receiving terminal, and the identification information are transmitted to the server, respectively.
In step S43, it is determined whether the transmitting terminal and the receiving terminal are matched based on the location information of the mobile terminal.
When it is preliminarily determined that the transmitting terminal and the receiving terminal are successfully matched, step S44 is executed; when it is preliminarily determined that the transmitting terminal and the receiving terminal fail to be matched, step S49 is performed, and a data transmission path cannot be established between the two terminals.
In step S44, it is determined whether the transmitting terminal and the receiving terminal are matched based on the finger-cut time information.
Specifically, the total time of the continuous finger-stroke operation can be determined according to the finger-stroke time information; and judging whether the total time of the continuous finger-stroke operation is within the finger-stroke operation time range. When the judgment result is yes, step S45 is executed; if the result of the determination is negative, it indicates that the matching between the two terminals has failed, and step S49 is executed.
In step S45, it is determined whether the transmitting terminal and the receiving terminal are matched based on the finger trace information.
When the difference between the slip-out angle and the slip-in angle is smaller than the angle threshold, performing step S46; when the difference between the slip-out angle and the slip-in angle is not less than the angle threshold, step S49 is performed.
The steps S41 to S45 complete the first round of matching, which may be the same as the steps S31 to S35 shown in fig. 4, and are not described herein again.
In step S46, it is determined whether there is only one pair of matching terminals.
When there is only one pair of matching terminals, step S48 is performed; when there are a plurality of pairs of matching terminals, step S47 is performed.
In this embodiment, the multiple-pair matching may be that one transmitting terminal corresponds to a plurality of receiving terminals, that is, "one-to-many", or that a plurality of transmitting terminals correspond to a plurality of transmitting terminals and a plurality of receiving terminals, that is, "many-to-many".
In step S47, a second round of matching verification is performed using the verification code.
After the first round of matching verification, for the situation that a plurality of candidate receiving terminals still exist, the verification codes can be used for distinguishing so as to realize accurate one-to-one.
Specifically, when the number of candidate receiving terminals is greater than the threshold value of the number of candidate terminals, the server transmits the verification codes of the plurality of candidate receiving terminals to the transmitting terminal, and the transmitting terminal responds to the verification code of the target receiving terminal input by the user and transmits the verification code to the server. And the server establishes a matching relation for the sending terminal and the target receiving terminal according to the received verification code.
When the number of the candidate receiving terminals is not larger than the threshold value of the number of the candidate receiving terminals, the server sends verification codes of the candidate receiving terminals to the sending terminal, the sending terminal responds to the identification code selected by the user and sends the verification code to the server, and the server establishes a matching relation for the sending terminal and the target receiving terminal according to the received verification codes.
Due to the limitation of the screen of the mobile terminal, when the number of the candidate receiving terminals is large, the screen may not be capable of completely displaying all the information of the candidate receiving terminals, so that a mode of inputting an identification code can be adopted; and when the number of the candidate receiving terminals is smaller, the screen of the mobile terminal can finish displaying the information of the candidate receiving terminals, and the user can adopt a mode of selecting the identification code.
In one embodiment, the threshold number of candidate terminals may be 5. Of course, the threshold of the number of candidate terminals may be adjusted according to actual needs and the screen size of the mobile terminal.
The two-round matching can also be performed in a combined one-round matching.
Preferably, the International Mobile Subscriber Identity (IMSI) of the mobile terminal may be associated with the user name and stored in the server.
The user name used may be the real name of the user in the communications carrier user database. However, in consideration of the security of the personal profile of the user, in a preferred mode, the user name may be a nickname of the user, that is, the IMSI of the mobile terminal is associated with the nickname of the terminal user, which is convenient for operation and effectively protects the personal profile of the user. More preferably, each nickname is guaranteed to be non-duplicate and unique.
In this way, in the case where a plurality of candidate receiving terminals still exist after the server has performed the first round of matching, the server can transmit the user nicknames of the plurality of candidate receiving terminals to the transmitting terminal.
If the user of the sending terminal knows the nickname of the target receiving user in advance (for example, by means of talking, short message notification, storage in advance and the like), the target receiving terminal can be selected from a plurality of candidate receiving terminals directly according to the nickname. Correspondingly, the server establishes a matching relationship between the sending terminal and the target receiving terminal.
By adopting the method, irrelevant candidate receiving terminals can be quickly eliminated, and the matching relation with the target receiving terminal can be quickly and accurately established.
In step S48, a data transmission channel is established between the transmitting terminal and the receiving terminal that have successfully matched.
After a transmission channel is established, a client can select file data to perform subsequent data transmission; before the finger-print operation is performed, the document data to be transmitted may be selected, which is not limited herein.
By using the verification code, the mobile terminal after multiple matching verification can be finally matched, and the target receiving terminal can be determined from a plurality of candidate receiving terminals according to the verification code, so that the matching verification is finally completed.
The method of the above embodiment may be implemented in a software manner, for example, a mobile phone sharing client may be installed on a mobile phone, and the client may be activated.
It should be noted that the above embodiments are only exemplary, and the verification matching of the two mobile terminals can be performed according to one or a combination of several information of the position information, the finger stroke time information, the finger stroke track information, and the verification code according to actual needs.
In the embodiment, the two mobile terminals are verified and matched, but by adopting the method disclosed by the invention, a plurality of mobile terminals can also be verified and matched. For example, there may be one sending handset and two receiving handsets, and the user may perform a continuous pointing operation on the touch screens of the three handsets. The method comprises the steps of obtaining finger stroke time information, finger stroke track information and mobile phone position information on touch screens of three mobile phones, and carrying out verification matching according to the finger stroke time information, the finger stroke track information and the mobile phone position information. When the matching is successful, the sending mobile phone can send the data information to the two receiving mobile phones, so that the information sharing among multiple terminals is realized.
By utilizing the method, the data information such as audio/video files, contact information, funny short messages, wonderful webpages, cool applications and the like on the mobile phone can be quickly and conveniently shared, and the method is particularly suitable for data sharing of users in gathering occasions such as business, leisure, entertainment and the like.
Fig. 6 shows an arrangement for data transmission between mobile terminals according to the invention.
The mobile terminals of the invention are all provided with touch screens. 3G smart phone terminals with larger touch screens are more and more popular, and the development and application of mainstream smart phone operating systems based on apple iOS, Google Android, Microsoft Windows Phone 7 and the like are easier and the upgrading is more convenient.

The sliding-in angle determining module 34 is configured to determine a sliding-in angle of the continuous finger stroked on the second touch screen according to the second stroke track information.
Preferably, the slide-out angle determining module 33 and the slide-in angle determining module 34 may fit the trajectory of the pointing direction by using a least square method, and calculate the slide-out angle of the continuous finger on the first touch screen and the slide-in angle of the continuous finger on the second touch screen according to the trajectory.
The angle comparison module 32 may compare the difference between the slip-out angle and the slip-in angle to an angle threshold.
When the difference between the slip-out angle and the slip-in angle is smaller than the angle threshold, the matching judgment module 31 may judge that the sending terminal and the receiving terminal are successfully matched; when the difference between the slip-out angle and the slip-in angle is not smaller than the angle threshold, the matching determining module 31 may determine that the matching between the transmitting terminal and the receiving terminal is unsuccessful.
Preferably, the matching verification unit 3 may further include a time judgment module 35. The time judging module 35 is used for judging whether the total time of the continuous finger-stroke operation is within the finger-stroke operation time range.

If the finger stroke operation time range is set to be too short, the finger stroke process cannot be completed; if the finger stroke operation time is too long, it is likely to conflict with subsequent matches. Those skilled in the art will understand that the time range of the finger stroke operation can be adjusted according to actual needs.
When the total time of the finger-print continuation operation is within the finger-print operation time range, the matching judgment module 31 may preliminarily judge that the receiving terminal and the sending terminal are successfully matched; when the total time of the finger print continuation is within the finger print operation time range, the matching judgment module 31 may judge that the receiving terminal and the transmitting terminal are unsuccessfully matched.
Preferably, the matching verification unit 3 may further include an IP comparison module 36 and a base station comparison module 37. The IP comparison module 36 is configured to determine whether the IP of the sending terminal and the IP of the receiving terminal are in the same network segment for the case that the sending terminal and the receiving terminal belong to the same operator; the base station comparing module 37 is used for judging whether the base station to which the transmitting terminal belongs is the same as the base station to which the receiving terminal belongs.
When the IP of the sending terminal and the IP of the receiving terminal are in the same network segment, the matching judgment module 31 preliminarily judges that the sending terminal and the receiving terminal are matched; when the IP of the sending terminal and the IP of the receiving terminal are in different network segments, the matching judgment module 31 judges that the sending terminal and the receiving terminal are not matched.
When the base station to which the transmitting terminal belongs is the same as the base station to which the receiving terminal belongs, the matching judgment module 31 preliminarily judges that the transmitting terminal and the receiving terminal are matched; when the base station to which the transmitting terminal belongs and the base station to which the receiving terminal belongs are different, the matching judgment module 31 judges that the transmitting terminal and the receiving terminal are not matched.
Preferably, the sending terminal may further be provided with a verification code unit 14, the receiving terminal may be provided with a verification code unit 24, and accordingly, the matching verification unit 3 may be provided with a verification code distribution module 38.

Specifically, the validation code assignment module 38 transmits the validation codes of the plurality of candidate receiving terminals to the transmitting terminal.
When the number of candidate receiving terminals is large (for example, the number of candidate receiving terminals is larger than the threshold value of the number of candidate terminals), the verification code unit 14 of the transmitting terminal transmits the verification code of the target receiving terminal selected by the user to the matching verification unit 3 in response to the verification code. The matching judgment module 31 establishes a matching relationship between the sending terminal and the receiving terminal corresponding to the verification code.
When the number of candidate receiving terminals is small (for example, the number of candidate receiving terminals is smaller than the threshold value of the number of candidate terminals), the user can directly input the verification code of the target receiving terminal through the verification code unit 14 and send it to the matching verification unit 3. The matching judgment module 31 establishes a matching relationship between the sending terminal and the receiving terminal corresponding to the verification code.
And when the data transmission is finished, releasing the matching relation of the mobile terminal to prepare for next finger sharing operation.
Preferably, the transmitting terminal and the receiving terminal may be provided with a user name selecting unit 15 and a user name selecting unit 25, respectively; accordingly, the match verification unit 3 may be provided with an association module 39.
The association module 39 may associate an identification of the mobile terminal (e.g., an international mobile subscriber identity) with the username of the mobile terminal and store in memory.
The user name used may be the real name of the user in the communications carrier user database. However, in consideration of the security of the personal data of the user, in a preferred mode, the user name may be a nickname of the user, that is, the IMSI of the mobile terminal is associated with the nickname of the terminal user, which is not only convenient for operation, but also can effectively protect the personal data of the user. More preferably, each nickname is guaranteed to be non-duplicate and unique.
When there are a plurality of candidate receiving terminals, the server may transmit user names of the plurality of candidate receiving terminals to the transmitting terminal. At this time, the sending end user already knows the user name of the target receiving user in various ways, so that the sending end user can directly make a selection through the user name selection unit 15. In response to the selection, the sending terminal may send the username to the server. The matching judgment module 31 may establish a matching relationship between the sending terminal and the target receiving terminal according to the received user name.
