Description
Technical Field
The present invention relates to the field of communications, and more particularly, to a method and system for performing group functions.
Background
At present, there are two main ways for a user to transfer a file:
one way is to implement one-to-many data transmission by using bluetooth transmission, which is to search a service device capable of bluetooth connection and perform bluetooth connection with such a service device, and simultaneously acquire data information of the service device, identify a different service device for a matching tag corresponding to each service device, then generate a corresponding key for the service device to perform bluetooth binding, and send a control command to the service device to perform a corresponding action after completing bluetooth binding.
Another way is with social software, a user may create a social group, such as a WeChat group, a QQ group, etc., on the social software and then transmit a file in the social group. However, in many cases, a plurality of users only need to temporarily share files, and if a social group is created every time a file is transmitted, many useless groups and confusion on social software are caused, so that the user is inconvenient to remember and manage, and the user is troublesome to quit the group, so that the user needs to open the social software to find the group and quit. In addition, the file is transmitted through the social group and needs to be processed by the server, the speed of transmitting the file is greatly influenced by a network at the moment, particularly under the outdoor condition, a data network is unstable, the transmission speed is low when the file is transmitted greatly, and user experience is poor; secondly, if files are transmitted through the server, the hidden danger of privacy disclosure is inevitably generated.
However, at present, no matter whether the android device or the iOS device is used, when files are transmitted through bluetooth and Wi-Fi, only point-to-point transmission is supported, and one-time transmission to a plurality of devices is not supported; secondly, when files are transmitted by using Bluetooth and Wi-Fi, a transmission object needs to be selected, and when the number of peripheral devices of a user is large and if the name of a duplicate device exists, the user can hardly select the transmission object quickly.

Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a block diagram illustrating a system 100 for implementing group functions according to an exemplary embodiment of the present invention. The system 100 may be installed in a variety of electronic devices to enable the electronic devices to implement group functionality. For ease of explanation, it is assumed that a first device has installed the system 100 and can use the system 100 with other devices in which the system 100 is installed to implement group functionality.
The system 100 according to an exemplary embodiment of the present invention may include a group opening module 110, a group creation module 120, and a connection module 130.
The group opening module 110 may be configured to open a group function, and the group creation module 120 may be configured to create a group. In an exemplary embodiment of the present invention, the first device may open the group function using the group opening module 110 and create a group using the group creation module 120 and then join other devices, in which the system 100 is also installed, to the own created group, or the first device may open the group function using only the group opening module 110 and then join a group created by another device without creating a group, which will be explained in detail below.
When a group function is turned on in a first device and a group is created, the connection module 130 may search for one or more devices that have turned on the group function and do not join the group created by the first device and determine a distance and a pointing relationship between the first device and the one or more devices, and when a distance between the first device and a second device of the one or more devices is within a preset distance range and a pointing relationship exists between the first device and the second device, the connection module 130 may establish a direct connection between the first device and the second device and add the second device to the group. Subsequently, the second device joining the group may also search for other devices that have opened the group function and are not joined in the preset distance range of the group, so as to join the device having a pointing relationship with the second device in the group.
And when the group function is turned on in the first device but a group is not created, the first device may be added to another group created by another device in a manner similar to the manner in which the first device adds the second device to the group created by the first device as described above. After the first device has been added to another group created by another device, the connection module 130 of the first device may further search for at least one device that has opened a group function and does not join the another group and determine a distance and a pointing relationship between the first device and the at least one device, and establish a direct connection between the first device and a third device among the at least one device and add the third device to the another group when a distance between the first device and the third device is within the preset distance range and there is a pointing relationship between the first device and the third device.
That is, in an exemplary embodiment of the present invention, devices already in a group may search for and join devices that satisfy the above distance and pointing relationship conditions, but do not join the group, thereby establishing a decentralized temporary group. This will be explained in more detail later.
In an exemplary embodiment of the present invention, the existence of a pointing relationship between devices means that one device points to another device or that the other device points to the device. Whereas the absence of a pointing relationship between devices means that one device is not pointing at another device and that the other device is not pointing at the device.
Further, in the exemplary embodiments of the present invention, for convenience of explanation and distinction, a device that creates a group (e.g., the above-described first device) and a device that has joined the group (e.g., the above-described second device that has joined the group) may be referred to as a group device, and a device that will join the group (but has not yet joined the group) (e.g., the above-described other device searched by the second device) may be referred to as a target device.
According to an exemplary embodiment of the present invention, when device a turns on the group function and creates a group, device a may be referred to as a group device. After the group device a determines that the target device B points to the group device a within the preset distance range, the group device a may establish a direct connection with the target device B, and the group device a joins the target device B to the group of the group device a. At this time, the target device B becomes a group device B, and the group device B can also similarly search for other devices within the preset distance range.
Then, when the group device B determines that the target device C with the group function turned on points to the group device B within the preset distance range, the target device C may establish a direct connection with the group device B, and the group device B joins the target device C to the group where the group device a and the group device B are located. At this time, the target device C becomes a group device C, and the group device C can also similarly search for other devices within the preset distance range.
Optionally, when the group device a determines that the group device a points to the target device D with the group function started within the preset distance range, the group device a may also establish a direct connection with the target device D, and the group device a joins the target device D to the group of the group device a.
Further, according to an exemplary embodiment of the present invention, when the group device a determines that a specific device having a group function turned on has a pointing relationship with the group device a within a preset distance range, and the group device B determines that the specific device also has a pointing relationship with the group device B within the preset distance range, one or both of the group device a and the group device B may establish a direct connection with the specific device and join the specific device in a group of the group device a and the group device B.
For example, when group device a determines that a specific device having a group function turned on has a pointing relationship with group device a within a preset distance range, and group device B determines that the specific device also has a pointing relationship with group device B within the preset distance range, the specific device may compare the distance to group device a with the distance to group device B. For example, if the distance to group device a is greater than the distance to group device B, the particular device may establish a direct connection with group device B and join the group of group device a and group device B; if the distance to group device a is less than the distance to group device B, the particular device may establish a direct connection with group device a and join the group of group device a and group device B.
Alternatively, when the first group device determines that the specific device having the temporary group function turned on has a pointing relationship with the first group device within a preset distance range and the second group device determines that the specific device has a pointing relationship with the second group device within a preset distance range (the groups in which the first group device and the second group device are located are different and are the first group and the second group respectively), the specific device may join the first group and the second group at the same time, or the specific device may select the two groups to determine to join one of the first group and the second group before establishing a direct connection with the first group device and the second group device.
Further, according to an exemplary embodiment of the present invention, when the device a opens the group function but does not create a group, if the device a can be searched by the group device X in another group and the device a and the group device X have a pointing relationship within a predetermined distance range, the group device X can add the device a to the other group, at which time, the device a becomes the group device a of the other group. Subsequently, the device a may also search for other devices within the preset distance range, which is not described herein again.
However, it should be understood that the above description with reference to the drawings is only listed for clearly understanding the technical idea of the present application, and the present application is not limited thereto, and the above-described manner of establishing a group and joining a group is also applied to other cases, for example, even if the first device turns on a group function and creates a group, the first device may be added to a group created by other devices in the above-described manner of joining a group.
The manner in which the group device determines the distance and pointing relationship with the target device is described in detail below.
In an exemplary embodiment of the present invention, the connection module 130 of the group device may include a positioning module (not shown), for example, a UWB positioning module, an RFID positioning module, a bluetooth positioning module, a WiFi positioning module, or a ZigBee positioning module, etc., which is used to determine the distance and pointing relationship between the group device and the target device. For example, when the positioning module included in the connection module 130 is a ZigBee positioning module, a certain number of base stations may be deployed in a specific environment through ZigBee technology, and when the base stations receive information sent by devices in real time, the information is uploaded to a server, and the distance and the pointing relationship between the devices may be determined through calculation processing by the server. For another example, when the positioning module included in the connection module 130 is a UWB positioning module, the positioning module may be configured to determine a distance and an angle between the group device and the target device, wherein the connection module 130 may determine that a pointing relationship exists between the group device and the target device when the angle between the group device and the target device is within a preset angle range.
By way of example only, an example of determining the distance and pointing relationship between a target device and a group device using UWB as a positioning module (hereinafter referred to as a UWB positioning module (not shown)) will be described in detail below in conjunction with fig. 2 and 3 (detailed description will be given below with an example of determining whether a target device is pointing to a group device).
Fig. 2 is a diagram illustrating determining coordinates of a target device according to an exemplary embodiment of the present invention; and fig. 3 is a diagram illustrating determining a distance between a target device and a group device according to an exemplary embodiment of the present invention.
As shown in fig. 2, the UWB positioning module of the group device includes three antennas for illustration (the UWB positioning module may also include more than three antennas). Three antennas of the UWB positioning module can be respectively P in a preset coordinate system1、P2And P3Wherein the three antennas P are connected1、P2And P3The resulting circumcenter O of the triangle may be the origin of coordinates of the preset coordinate system. Here, OP1＝OP2＝OP3，P1May be P1(x1，y1，0)，P2May be P2(x2，y20), and P)3May be P3(x3，y30), in an exemplary embodiment of the invention, the coordinates of all three antennas are known. The target device may be abstracted as a point P in the preset coordinate system, and the coordinate of the point P may be P (x, y, z).
An example of determining the distance of each of the three antennas to the target device is described below.
As shown in FIG. 3, the antenna P of the group device1Can be at time T1Sending a data packet to a target device, the target device being operable at time T2Receiving antenna P from group device1At time T3To the antenna P1Sends back complex data packets and antenna P1Can be at time T4A reply packet is received from the target device. Here, in FIG. 3, TdelayIs the time T at which the target device receives the data packet2And the time T of sending back the complex data packet3The time delay therebetween. T isdelayMay be preset. The TF is a period of time during which a packet or a reply packet is transmitted. The reply packet may include a time T for the target device to receive the packet2About TdelayAnd a time T for the target device to send the reply packet3The information of (1).
The group device may calculate a group in a preset coordinate system by equation (1) belowAntenna P of group equipment1Distance d from target device P1：
Wherein C is the wave velocity.
In the same way, the antennas P of the target device and the group device can be calculated respectively2And P3A distance d between2And d3。
As shown in fig. 2, d has been calculated due to the above steps1、d2And d3Therefore, the coordinates P (x, y, z) of the target device can be calculated by the following equations (2) to (4):
thus, the distance OP between the group device and the target device can be calculated.
In addition, it can be calculated by the following equation (5)
And
wherein the vector of the Y axis is obtained by obtaining the coordinates P (x, Y, z) through the above steps
The coordinates are set to (0,1, 0).
When the angle θ is less than or equal to the preset angle, it may be determined that the target device is pointed to the group device.
The above examples describe a process of calculating the distance and angle between a group device and a target device based on UWB technology. Those skilled in the art will appreciate that this description is by way of example only, and that the scope of the invention is not limited thereto.
Further, in the exemplary embodiments of the present invention, when a device is added to a group, the device may establish a direct connection only with the device that added the device to the group, or may also establish a direct connection with other devices in the group after joining the group.
The following describes in detail the manner of data transmission between devices in a group.
Fig. 4 is a diagram illustrating a data transmission manner between devices in a group according to an exemplary embodiment of the present invention.
As shown in fig. 4, after the device a determines that the device B, the device C, and the device D have a pointing relationship with the device a within the preset distance range, the device a may establish a direct connection with the device B, the device C, and the device D, and join the device B, the device C, and the device D into a group created by or in which the device a is located, and after the device C determines that the device E has a pointing relationship with the device C within the preset distance range, the device C may establish a direct connection with the device E, and join the device E into a group in which the device C is located, at this time, the device E is indirectly connected with the device a, the device B, and the device D in the group.
In this case, when the a device transmits data, the B device, the C device, and the D device may simultaneously receive the data transmitted by the a device, and after the C device finishes receiving the data, the C device may forward the data to the E device.
Also, in this case, when the C device transmits data, the a device and the E device may simultaneously receive the data transmitted by the C device, and after the a device finishes receiving the data, the a device may forward the data to the D device and the B device.
That is, when a device in a group sends data, the device in the group directly connected to the device receives the data and forwards the data to the device in the group indirectly connected to the device step by step.
Fig. 5 is a diagram illustrating a data transmission manner between devices in the group of fig. 4 when there is a device in the group to exit according to an exemplary embodiment of the present invention.
In the group of fig. 4, if the C device is disconnected from the a device (or the C device exits the group), the C device may transmit information about the E device to the a device, and then the a device may establish a direct connection with the E device. Alternatively, if the C device is disconnected from the a device (or the C device exits the group), the C device may also transmit information about the a device to the E device, and then the E device may establish a direct connection with the a device. That is, when the C device is disconnected from the a device, a direct connection is established between the a device and a device in the group that is directly connected to the C device, so that the disconnection of the C device in the group does not affect one-to-many data transmission between other devices in the group.
In this case, as shown in fig. 5, when the a device transmits data, the E device, the B device, and the D device may simultaneously receive the data transmitted by the a device.
Also, in this case, when the E device transmits data, the a device may receive the data transmitted by the E device, and after the a device completes receiving the data, the a device may forward the data to the B device and the D device.
Fig. 6 is a diagram illustrating a data transmission manner between devices in a group according to another exemplary embodiment of the present invention.
As shown in fig. 6, after the device a determines that the device B has a pointing relationship with the device a within the preset distance range, the device a may establish a direct connection with the device B, and join the device B into a group of the device a; after the B device determines that the C device has a pointing relationship with the B device within a preset distance range, the B device may establish a direct connection with the C device and join the C device into the group, and the B device may send connection information with the C device to the a device to which the B device has been connected, so that the a device may establish a direct connection with the C device newly joining the group. Alternatively, after the C device joins the group, the B device may transmit all its connection information to the C device, so that the C device newly joining the group may establish a direct connection with all devices in the group.
In this case, when the a device transmits data, the B device and the C device may simultaneously receive the data transmitted by the a device. That is, after a device is added to a group, the device establishes direct connections with all devices in the group, and when any device in the group transmits data, other devices in the group than the any device simultaneously receive the data.
In this case, when any device in the group disconnects or exits the group, one-to-many data transmission between other devices in the group is not affected.
In addition, for example, when a specific device joined by a certain device in the group cannot establish a direct connection with the a device due to a long distance, the specific device may search for and establish a direct connection with a device in the group that is within a certain distance range and directly connected with the a device, and when the a device transmits data, the device in the group that is within a certain distance range and directly connected with the a device may receive the data and may forward the data to the specific device. Optionally, when the a device sends data, the certain device that causes the specific device to join the group may forward the data to the specific device.
The devices in the group may connect and transfer data based on the bluetooth protocol, but are not limited thereto, e.g., may also be based on WiFi, RFID, NFC protocols, etc.
The operation of the devices in the group to exit the group is described in detail below. The system 100 according to an exemplary embodiment of the present invention may further include an exit module (not shown) that may be configured to cause a device to exit the joined group when the device performs a predetermined action.
Fig. 7 illustrates a schematic diagram of a device exiting a group according to an exemplary embodiment of the present invention. For example only, in FIG. 7, devices in the group may exit the group by flipping.
The motion state of the device can be identified according to data of a gyroscope, a sensor and the like in the device, and when any device in the group is turned from the front side to the back side within a preset time range (for example, the time of turning degree close to 180 degrees is less than 400ms), the device can directly exit the group.
The preset time range may be an average value obtained by a test with a right-hand flip phone. For example, the preset time range may be set to 400 ms.
As shown in (1) and (2) of fig. 7, the turning of the device from the horizontal front side to the horizontal back side may mean that the absolute value of the number of degrees of the turning of the device about the Y axis is greater than a preset number of degrees, for example, 175 degrees. That is, when the device in the vertical screen is rapidly turned from the front to the left or from the front to the right within a preset time range by more than a preset number of degrees, the device can directly exit the group.
As shown in (3) and (4) of fig. 7, the turning of the device from the horizontal front side to the horizontal back side may mean that the absolute value of the number of degrees of the turning of the device about the X axis is greater than a preset number of degrees, for example, 175 degrees. That is, when the device on the horizontal screen is turned inwards or outwards from the front side within a preset time range, the device can directly exit the group.
Examples of the device flipping quickly are not limited to the above examples, and for example, when the device in the landscape is flipped from the front side quickly to the left or from the right more than a preset number of degrees within a preset time range, the device may also directly exit the group.
The operation of the gyroscope in the device to calculate the flip angle of the device to identify the motion state of the device will be described in detail below in conjunction with fig. 8.
Fig. 8 illustrates a flowchart for identifying a motion state of a device according to an exemplary embodiment of the present invention. By way of example only, a gyroscope is used in fig. 8 to identify the motion state of the device.
The device may register the gyroscope and may specify a polling interval of the gyroscope after the device joins the group (step S801), for example, the polling interval may be specified as 20 ms.
The gyroscope may acquire the speed of the apparatus turning around the X-axis or the Y-axis (step S802), and may calculate the absolute value θ of the angle of the apparatus turning around the X-axis or the Y-axis within a preset time range (e.g., 400ms)xAnd thetay(step S803). When theta isxAnd thetayWhen it is greater than or equal to the preset value or close to the preset value (for example, the preset angle may be pi) (yes at step S804), the device may unregister the gyroscope, and at this time, the device may exit the group (step S805). When theta isxAnd thetayIf the value is smaller than the preset value or not close to the preset value (no in step S804), the device may continue to remain in the group.
The above-described operation of the device to exit the group is only an example, and the operation of the device to exit the group may further include other predetermined actions, such as pressing a predetermined key, tapping a screen, shaking the device, and the like. The operation of the device to exit the group may also be customized by the user. When any device in the group performs a predetermined action, the any device exits the group.
