Detailed Description

The embodiments of the present application will be described below with reference to the drawings. The terminology used in the description of the embodiments herein is for the purpose of describing particular embodiments herein only and is not intended to be limiting of the application.

First, an application scenario of the embodiment of the present application is described. The technical scheme provided by the embodiment of the application can be applied to various Wi-Fi P2P connection scenes, and for convenience of description, the Wi-Fi direct connection scene is taken as an example in the embodiment for exemplary description.

Fig. 1 is a schematic diagram of a system architecture of a wireless communication method provided in an embodiment of the present application, and as shown in fig. 1, the system may include a plurality of terminal devices (three are exemplarily illustrated in the figure), and Wi-Fi direct connections may be established between the terminal devices, and data may be shared with each other through the established connections. The terminal device may be the mobile phone 1100, the tablet computer (pad)1200, and the television 1300 shown in fig. 1, or may be a terminal device supporting a Wi-Fi direct connection function, such as a large screen device, a desktop computer, a notebook, or a wearable device, which is not shown.

Specifically, a wireless connection can be established between terminal devices by using a standard Wi-Fi direct connection technology, that is, a group (group) can be established between terminal devices, in the group, one terminal device plays a Group Owner (GO), other terminal devices play Group Clients (GC), and a Wi-Fi direct connection is established between the GO and each GC.

The connection establishment process between the GO and any GC may include device discovery (device discovery) and group establishment (group format), and the two devices discover each other through the device discovery process, and perform GO negotiation and exchange security configuration information through the group establishment process.

Fig. 2 is a schematic view of an application interface provided in an embodiment of the present application, and as shown in fig. 2 (a), a user may click a Wi-Fi direct option 101 in a Wi-Fi setup interface 10 on a mobile phone 1100 to open a Wi-Fi direct interface 20, and start a Wi-Fi direct function. After the Wi-Fi direct function is started, the terminal device may initiate a device discovery process to search for surrounding Wi-Fi direct devices, as shown in (b) of fig. 2, prompt information such as "searching" may be displayed in the available device bar 202 to prompt the user that an available Wi-Fi direct device is being searched. In the Wi-Fi direct interface 20, the user may edit the Wi-Fi direct device name of the home terminal through the device name option 2011 in the my device bar 201, such as the Wi-Fi direct device name "AAA" of the mobile phone 1100 shown in fig. 2.

The Wi-Fi direct connection establishment procedure is described below by taking two terminal devices (a first terminal device and a second terminal device, respectively) as an example.

Fig. 3 is a schematic flowchart of a device discovery process provided in an embodiment of the present application, and as shown in fig. 3, the device discovery process may include: a scan phase and a find phase.

A scanning stage: after the device discovery process is started, the terminal device (including the first terminal device and the second terminal device) may first enter a scanning phase, in which the terminal device sends Probe Request (Probe Request) frames on all frequency bands supported by the terminal device, and the terminal device does not process Probe Request frames from other devices in this phase, and may receive Probe Response (Probe Response) frames to discover other terminal devices in a listening state.

A discovery phase: and after the scanning stage is finished, the terminal equipment enters a discovery stage. In this phase, the terminal device switches back and forth between a listening state (listen state) and a search state (search state).

In the listening state, the terminal device randomly selects one of the 1, 6 and 11 frequency bands (i.e. ch1, ch6 and ch11 in the figure, which are called social channels) as a listening band (listen channel), listens to the probe request frame and replies to the probe response frame accordingly. For example, in fig. 2, the listening band of the first terminal device is 1, and the listening band of the second terminal device is 6. The terminal equipment enters a searching state after monitoring for a period of time.

In the search state, the terminal device will transmit probe request frames on

frequency bands

1, 6, and 11, respectively. When two terminal devices are in the same frequency band, a frame transmitted by one terminal device may be received by the other terminal device, for example, in fig. 2, the second terminal device listens to the probe request frame transmitted by the first terminal device on ch6, and replies a probe response frame to the first terminal device correspondingly.

The terminal device completes the interaction of the probe request frame and the probe response frame, that is, finds the Wi-Fi direct device, and may store device information of the opposite device, including a Media Access Control (MAC) address, a device type (device type), a device name (device name), and the like.

As shown in (c) of fig. 2, once the terminal device searches for the Wi-Fi direct device, the interface is updated to display the searched Wi-Fi direct device, and as shown in the available device column 202, the searched "BBB" (device name of pad 1200) and "CCC" (device name of tv 1300) are displayed. The user may select a certain Wi-Fi direct device in the interface to establish a connection with, for example, as shown in (c) and (d) of fig. 2, the user may click "BBB" to establish a connection with.

After the user selects the Wi-Fi direct device to be connected, the terminal device may perform a Group establishment procedure (corresponding to the start of establishing a Group in the drawing) to prepare for constructing a Group, where the Group establishment procedure may include a GO negotiation (GON) procedure and a security configuration (provisioning) procedure. The GON process is used for negotiating who makes GO, and after the GON process is executed, the safety configuration process is carried out, wherein the process mainly utilizes a Wi-Fi simple configuration (WSC) protocol to negotiate safety configuration information.

After the group establishment process is finished, the GC applies for an Internet Protocol (IP) address from the GO, the GO starts a Dynamic Host Configuration Protocol (DHCP) server to allocate an IP address to the GC, and after the IP address is allocated, the terminal device may update the connection state to notify the user that the connection is successful, for example, as shown in (d) of fig. 2, the connection state of updating "BBB" is "connected". After the group is disassembled, the IP address of the GC may be released.

After the group is established, GO and GC may also invite other terminal devices to join the group through a P2P invitation (P2P invitation) flow; during the device discovery process, the terminal device may also activate a previously established persistent group through the P2P invitation process.

In addition, as shown in (b) and (c) of fig. 2, the user may stop the search by clicking the stop icon 203 in the Wi-Fi direct interface 20 during the search; as shown in (d) of fig. 2, after the search is finished, the user may start the device discovery process again by clicking the search icon 204 in the Wi-Fi direct interface 20.

According to the Wi-Fi direct protocol, the IP address of the GO is 192.168.49.1 by default, namely the IP addresses of the GO in any group are 192.168.49.1, so that the IP addresses of the GO in different groups are overlapped and possibly interfere with each other, and the connection of the terminal equipment is unstable. Fig. 4 is a schematic view of an application scenario provided by an embodiment of the present application, for example, as shown in fig. 4, a1, B1, and C1 are a group, a2, B2, C2, and D2 are a group, a1 and a2 are GO of respective groups, and default IP addresses of both are 192.168.49.1. In a relatively small space (such as the same subway carriage), two groups simultaneously hope to internally share data such as audio, video or pictures; during communication, since the IP addresses of a1 and a2 are the same, each GC: b1, C1, B2, C2 and D2, which GO cannot be automatically determined to connect to, nor cannot be manually intervened; and after connecting the wrong GO, even if the wrong GO leaves, the GC still needs a long time to recover the initial state, and reconnects the new GO, which all affect the connection stability of the terminal device.

In addition, the address of the GC is dynamically allocated by the GO, which may also affect the connection stability of the terminal device. Fig. 5 is a schematic view of another application scenario provided in the embodiment of the present application, as shown in fig. 5, A3, B3, and C3 are a Group, and share data with each other, where A3 is GO; in the sharing process, A3 leaves, D3 hopes to join in a group, since A3 is GO, after the A3 leaves, the group is dispersed, B3 and C3 cannot share data continuously, and D3 cannot acquire IP addresses in time and cannot participate in data sharing, and B3, C3 and D3 need to be rebuilt to share data continuously.

In addition, the device discovery, negotiation and connection processes in the Wi-Fi direct connection protocol are complex, the required resources are excessive, the system overhead is large, and the device is too thick and heavy for thin devices; in addition, in the device discovery process, all the surrounding terminal devices in the device discovery state are scanned by default, so that the search efficiency is low, the operation interfaces corresponding to the search results are not concise, and if irrelevant terminal devices are searched and connected by mistake, the safety risk can also exist.

Therefore, the embodiment of the application provides a lightweight wireless communication method, which mainly simplifies Wi-Fi direct connection protocols and flows, cuts out group establishment and a P2P invitation flow, and adopts a decentralized mode for group management, namely two ends of equipment are connected in a peer-to-peer mode, and GO and GC role differentiation is cancelled; the IP address management can also adopt a decentralized mode, the unified management and distribution of the IP addresses of the GC are cancelled, the IP addresses are virtualized, the virtual IP addresses of the local terminal and the opposite terminal are locally managed by the terminal equipment, and data are forwarded by a data link layer, so that the problem that the automatic connection of the terminal equipment is unstable due to the overlapping of the IP addresses of GO is solved; in addition, in the process of equipment discovery, the terminal equipment is searched and filtered, so that the searching efficiency and safety are improved, and an operation interface is optimized. This technical solution is explained in detail below.

Fig. 6 is a flowchart illustrating a wireless communication method according to an embodiment of the present application, and as shown in fig. 6, the wireless communication method according to the embodiment may include the following steps:

and S110, the first terminal equipment responds to the connection triggering operation of the user and searches for second terminal equipment meeting the filtering condition of the local terminal.

And S120, the first terminal device sets the Wi-Fi direct connection state between the first terminal device and the searched second terminal device to be a connected state.

Specifically, a user may start the Wi-Fi direct function through a connection triggering operation, where the connection triggering operation may be a triggering operation of the target system function by the user, for example, as shown in fig. 3 (a), the user may click a Wi-Fi direct option in a Wi-Fi setting interface to start the Wi-Fi direct function; as another implementation manner, a shortcut option may also be provided on the first terminal device, for example, as shown in fig. 7, a Wi-Fi direct icon may be provided in the drop-down notification bar, and the user may start a Wi-Fi direct function by clicking the icon. The Wi-Fi direct connection function can be started only when the Wi-Fi function is started, so that when connection triggering operation of a user is received, the terminal equipment can automatically start the Wi-Fi function and then start the Wi-Fi direct connection function when the Wi-Fi function is not started; the user can also be prompted to start the Wi-Fi direct function after the user authorizes to start the Wi-Fi function.

In order to improve the convenience of the user, in this embodiment, when the user starts a target Application (APP) or a target function, the target APP or the target function may be triggered to automatically start the Wi-Fi direct function. For example: after a user clicks a gallery icon to open a gallery, the gallery automatically starts a Wi-Fi direct connection function; for another example, when a user clicks a video call function and initiates a video call, the video call function automatically starts a Wi-Fi direct connection function, searches for available Wi-Fi direct devices and establishes a connection.

It should be understood that the target application is not limited to the gallery, and may also be a file management APP or other instant messaging APPs, and the like, which is not particularly limited in this embodiment of the application.

Certainly, the user may start the Wi-Fi direct function by inputting a voice command, which is not particularly limited in this embodiment. In addition, the connection triggering operation may also be a click operation of a search icon in the Wi-Fi direct interface after the user clicks the Wi-Fi direct option to open the Wi-Fi direct interface.

After detecting the connection triggering operation of the user, the first terminal device may respond to the operation, and enter the device discovery process to perform filtering search to search for a second terminal device that meets the filtering condition of the local terminal, where the filtering condition may be preset by the system, for example: the first terminal equipment automatically searches for second terminal equipment logging in the same system account; in order to improve the flexibility of the user, the first terminal device may also provide a filtering condition setting function for the user to set the filtering condition autonomously.

In a specific implementation, as shown in (a) of fig. 8, in addition to the various function options shown in fig. 2, a filter condition option 203 may be included in the Wi-Fi direct interface 20, and a user may click the filter condition option 203 to open the filter condition interface 40; as shown in (b) of fig. 8, various options of filter conditions may be included in the filter condition interface 40, and a user may set a desired filter condition in the filter condition interface 40.

Specifically, as shown in fig. 8 (b), the filtering conditions may include system account filtering, group filtering, password filtering, voice filtering, Near Field Communication (NFC) filtering, and the like, switch controls 401 to 405 corresponding to each filtering condition may be provided in the filtering condition interface 40, and a user may select to turn on one or more filtering conditions through the switch controls, that is, the filtering conditions may include one or more filtering conditions.

For system account filtering, if the system account filtering is started by a user, the first terminal device can automatically search a second terminal device which logs in the same system account with the first terminal device in the searching process. Optionally, in the embodiment of the present application, the filtering is not limited to filtering the system account, and in a specific implementation, other accounts may also be filtered.

For group filtering, if a user establishes a target group in advance, such as a family group (including information related to terminal devices of all members of the family) and an adult group (not including information related to terminal devices held by minors among the family members), the group filtering may be started and a group filtering condition may be added when performing terminal search filtering. As shown in the figure, an editing option 4021 of a group name may be set in a column of the group filtering option for a user to edit a specific condition of group filtering, and optionally, the specific condition of group filtering may also be other group identification information such as a group number, which is not particularly limited in this embodiment of the present application. If the group filtering is started, the first terminal device may automatically search for the second terminal device in the target group selected by the user in the search process. For example, the user sets the group name in the group filter as a family group, and the first terminal device searches for the terminal devices (i.e., the second terminal devices) of the members in the family group.

For password filtering (also called password filtering), as shown in the figure, a password editing option 4031 may be set in the column of the password filtering option, and a user may set a password through the option while starting the password filtering. If the password filtering is started, the first terminal device can automatically search the second terminal device with the same password in the searching process. Optionally, in the embodiment of the present application, the password is not limited to be filtered, and in specific implementation, the text information may also be filtered.

For voice filtering, if the Wi-Fi direct connection function is started by a user, the first terminal device may automatically acquire voice information input by the user after the Wi-Fi direct connection function is started, generate filtering information according to the acquired voice information, and then automatically search for a second terminal device carrying the same filtering information in a detection message in a search process. For the filtering condition, in specific application, as the distance between the terminal devices is short, voice information can be sent out by any user around the terminal devices, and each terminal device can acquire the voice information and generate filtering information corresponding to the filtering condition according to the voice information.

For the NFC filtering, after the Wi-Fi direct connection function of the first terminal device is started, a user can carry out 'touch-touch' operation on the first terminal device and a second terminal device needing to be connected; the first terminal device may collect NFC information (for example, may be an NFC identifier) of the second terminal device, and then may search for the second terminal device corresponding to the collected NFC information in the search process. In specific implementation, the first terminal device may generate filtering information according to the NFC information of the local terminal and the acquired NFC information.

It can be understood that, if the user does not turn on any filtering condition, the first terminal device may also perform the procedures of device discovery and negotiation according to the standard Wi-Fi direct protocol to establish the connection.

As another implementation manner, the first terminal device may provide filtering functions corresponding to the various filtering conditions for the target application program to call, and the target application program automatically starts at least one filtering function after starting the Wi-Fi direct connection function, for example, after the user opens the gallery, the gallery starts the system account filtering function while starting the Wi-Fi direct connection function, and searches for a second terminal device that logs in the same system account; for another example, after the user opens the video call function, the user can input voice to initiate the video call, and the video call function starts the voice filtering function while starting the Wi-Fi direct connection function, and performs filtering search by using the voice input by the user as a filtering condition; or, the target APP or the target function may also provide a start option of the filtering function, and the user may start the corresponding filtering function by clicking the start option, and the following description exemplifies a process in which the user starts the Wi-Fi direct connection function and starts the filtering function, taking the target function as the video call function as an example.

Fig. 9 is a schematic view of some application interfaces provided in the embodiment of the present application, and as shown in fig. 9 (a), a video call icon 3012 may be provided in the drop-down notification bar, and a user may start a video call function by clicking the icon. After the video call function is started, the Wi-Fi direct function may be automatically started as described above, or the user may be prompted to authorize the start of the Wi-Fi direct function and the Wi-Fi function as shown in (b) of fig. 9. The user may select the start option to start the Wi-Fi direct function and the Wi-Fi function, as shown in (c) of fig. 9, after the Wi-Fi direct function is started, the video call function may provide start options of various filtering conditions corresponding to the filtering function: the mobile terminal comprises a system account filtering option 001, a group filtering option 002, a password filtering option 003, a voice filtering option 004 and an NFC filtering option 005, wherein for the system account filtering option 001, a first terminal device can search available Wi-Fi direct connection devices to establish connection after clicking; for the group filtering option 002 and the password filtering option 003, after the user selects, the video call function may provide an input interface for the user to input group information or password information; for the voice filtering option 004 and the NFC filtering option 005, after the user selects, the first terminal device may prompt the user to input voice information or perform a "touch and click" operation. Taking password filtering as an example, as shown in (c) and (d) of fig. 9, the user may click the password filtering option 003, and then may input the password in the pop-up input interface, where the number of digits of the password may be preset to 4 digits as shown in the figure, or may not be limited to the number of digits.

It can be understood that the video call function may also be presented to the user in the form of APP, and the specific implementation form is not particularly limited in this embodiment.

The following describes the search procedure of the first terminal device and the second terminal device in detail.

As described above, the first terminal device may carry filtering information corresponding to the filtering condition in the probe message, where the probe message may include a probe request message and a probe request response message, where the probe request message may specifically be a probe request frame, and the probe request response message may specifically be a probe response frame, that is, the first terminal device may carry the filtering information in the probe request frame and the probe response frame; the filtering information may be information such as a system account, a group identifier, a password, voice information, or NFC information in the filtering condition, and in order to improve the security of data transmission, the filtering information may also be character information generated according to the information such as the system account, the group identifier, the password, the voice information, or the NFC information. Correspondingly, when the first terminal device and the second terminal device search for each other, the method shown in fig. 10 may be used to implement the method, where fig. 10 is a schematic flow diagram of filtering search provided in the embodiment of the present application, and as shown in fig. 10, the method may include the following steps:

s111, the first terminal equipment broadcasts a detection request frame carrying the first filtering information.

Specifically, the second terminal device may also set the filtering condition, and the specific setting process is similar to the filtering condition setting process of the first terminal device, and is not described herein again. For convenience of distinction, the filtering information corresponding to the filtering condition in the first terminal device is referred to as first filtering information, and the filtering information corresponding to the filtering condition in the second terminal device is referred to as second filtering information.

After the Wi-Fi direct function is turned on, the first terminal device may broadcast the probe request frame on all channels or the social channel, as described above. In order to facilitate the peer device to know the filtering condition of the first terminal device, the first terminal device may carry the first filtering information in the probe request frame, so that the second terminal device may reply the response message when the filtering condition is satisfied, so as to inform the first terminal device that it meets the filtering condition.

Fig. 11 is a schematic frame structure diagram of a probe request frame and a probe response frame provided in an embodiment of the present invention, and as shown in fig. 11, the probe request frame may include a MAC header (MAC header), a frame body (frame body), and a Frame Check Sequence (FCS) field, where the MAC header may include some frame control information, address information, and the like; the frame body represents a data field, which is a payload; the FCS is used to guarantee frame data integrity.

The first filtering information may be carried in a frame body, and in a specific implementation, a characteristic parameter (charactercode) field may be added in the frame body, where the field indicates the first filtering information, and the characteristic parameter field may be located in any position of the frame body.

And S112, after receiving the detection request frame, the second terminal device judges whether the first filtering information and the second filtering information carried in the detection request frame are matched, and if so, the first terminal device is determined to meet the filtering condition of the local terminal.

The second terminal device may be similar to the first terminal device, respond to a connection trigger operation of the user, and start the Wi-Fi direct connection function, and a specific process is similar to a process in which the first terminal device starts the Wi-Fi direct connection function, and is not described here again.

After the Wi-Fi direct function is turned on, the second terminal device may monitor the probe request frame on the monitored frequency band as described above. If the second terminal device monitors the probe request frame, the first filtering information in the probe request frame can be extracted, and the first filtering information is compared with the filtering information (namely, the second filtering information) corresponding to the filtering condition of the local terminal, so that whether the first terminal device meets the filtering condition of the local terminal or not is determined. If the first filtering information is matched with the second filtering information, the first terminal equipment accords with the filtering condition of the second terminal equipment; if the first filtering information does not match the second filtering information, the second terminal device may discard the probe request frame and refuse to connect to the first terminal device.

In specific judgment, the account number, the group, the password, the NFC and other filtering conditions can be compared to judge whether the first filtering information is consistent with the second filtering information, and if so, the first filtering information and the second filtering information are considered to be matched; for voice filtering, the similarity between the first filtering information and the second filtering information can be compared, if the similarity meets the preset similarity, the first filtering information and the second filtering information can be considered to be matched, wherein the size of the preset similarity can be set according to actual needs.

And S113, the second terminal equipment returns a detection response frame carrying the second filtering information to the first terminal equipment.

If the second terminal device determines that the first filtering information carried in the probe request frame matches the second filtering information, the second terminal device may reply the probe response frame correspondingly to inform the first terminal device that the filtering conditions of the first terminal device and the second terminal device are consistent, that is, the first terminal device and the second terminal device mutually meet the filtering conditions of the opposite terminal. Or, the probe response frame may also carry acknowledgement information to inform the first terminal device that the filtering conditions of the two devices are consistent.

In order to improve reliability, the second terminal device may also carry second filtering information in the frame to inform the first terminal device of the local filtering condition.

As shown in fig. 11, the probe response frame may include a MAC header, a frame body, and FCS fields, and the second filtering information may be carried in the frame body of the probe response frame, similarly to the first filtering information, and a characteristic parameter field may be added in the frame body of the probe response frame, through which the second filtering information is indicated, wherein the characteristic parameter field may be located at any position of the frame body.

It can be understood that the probe request frame and the probe response frame may also carry device information such as a device identifier, a device name, a device type, and an MAC address of the local device, so as to be identified by the peer device.

And S114, after receiving the detection response frame, the first terminal device judges whether the second filtering information carried in the detection response frame is matched with the first filtering information, and if so, the second terminal device is determined to meet the filtering condition of the local terminal.

Specifically, the first terminal device receives the probe response frame returned by the second terminal device, and may determine that the second terminal device satisfies the local filtering condition.

As described above, in order to improve reliability, the probe response frame may carry second filtering information, and accordingly, the first terminal device may extract the second filtering information, compare the second filtering information with filtering information (i.e., the first filtering information) corresponding to the filtering condition of the local terminal, and determine whether the second terminal device meets the filtering condition of the local terminal based on a comparison result.

Specifically, if the first filtering information is matched with the second filtering information, it is indicated that the second terminal device meets the filtering condition of the first terminal device; if the first filtering information is not matched with the second filtering information, it indicates that the second terminal device is not in accordance with the filtering condition of the first terminal device, and the first terminal device may discard the probe response frame and refuse to connect with the second terminal device. The process of the first terminal device determining whether the first filtering information is matched with the second filtering information is similar to the process of the second terminal device determining the filtering information, and is not repeated here.

In a near field communication scenario, two communication parties can communicate with each other directly through a physical layer and a data link layer in the same local area network, and therefore, in this embodiment, when data transmission is performed between terminal devices, an IP address may not be carried in a data packet, and communication is performed through the physical layer and the data link layer. Correspondingly, the IP address assignment procedure may be cut down, and the group establishment procedure and the P2P invitation procedure may be cut down. In this way, the first terminal device searches for the second terminal device meeting the filtering condition, that is, the connection establishment is successful, the searched Wi-Fi direct connection state of the second terminal device can be displayed as the connected state, and similarly, the searched Wi-Fi direct connection state of the first terminal device can also be displayed as the connected state on the second terminal device. The second terminal device searched by the first terminal device may include one or more second terminal devices.

It is to be understood that the first terminal device and the second terminal device are only used for distinguishing descriptions, and a certain terminal device may be used as the first terminal device or the second terminal device, that is, both the first terminal device and the second terminal device may have functions of the other terminal device. For example: for the first terminal device, it may also receive a probe request frame broadcast by another terminal device (referred to as a third terminal device), and in a case that it is determined that the first filtering information matches filtering information of the third terminal device carried in the probe request frame, it may be determined that the third terminal device satisfies a filtering condition of the local terminal, and a probe response frame carrying the first filtering information may be returned to the third terminal device; correspondingly, the third terminal device may determine that the first terminal device satisfies the filtering condition of the third terminal device when it is determined that the filtering information of the third terminal device matches the first filtering information in the probe response frame. That is, any one terminal device may establish a Wi-Fi direct connection with another terminal device by using the search procedure performed by the first terminal device shown in fig. 10 and/or the search procedure performed by the second terminal device.

Taking an example that three terminal devices aaa, bbb and ccc search and establish connection with each other, assuming that filter conditions of aaa and bbb are the same, both login to the same system account, and the system account login by ccc is different from aaa and bbb. As shown in fig. 12 (a), the user clicks Wi-Fi direct options of the three terminal devices, respectively, to start a Wi-Fi direct function; as shown in (b) of fig. 12, three terminal devices start to search for Wi-Fi direct devices available around, as shown in (c) of fig. 12, aaa and bbb may search for each other to establish a connection, ccc does not satisfy the filtering condition of aaa and bbb, and is filtered out during the search of aaa and bbb, and cannot establish a connection with aaa and bbb.

As shown in fig. 13 (a), the user may also click the file management icons 5 of the three terminal devices to open the file management APP, and the file management APP automatically starts the Wi-Fi direct function; the aaa and bbb can search each other based on the same system account (filtering information) to establish connection, and the ccc cannot establish connection with the aaa and bbb. As shown in (b) in fig. 13, the user may view the connected Wi-Fi direct device in the other device column 501 of the file management interface 50 corresponding to the file management icon 5, where the user may click the browse icon 502 of the file management interface 50 to open the browse interface to browse files on the local computer and other devices, and the other device column 501 may be located in the browse interface; other functionality controls such as a search box may also be provided in the file management interface 50.

In order to be compatible with upper-layer applications such as a network layer, the first terminal device and the second terminal device can locally generate virtual IP addresses of both sides, wherein the virtual IP addresses are only locally effective, when data transmission is carried out, the IP addresses can not be carried in a first message sent outwards, after the second terminal device receives the first message, the virtual IP addresses can be added into a data packet transmitted to the network layer for the network layer to identify, wherein the target IP address is the virtual IP address of the second terminal device, and the source virtual IP address is the virtual IP address of the first terminal device; similarly, when the second terminal device returns the second message to the first terminal device, the second message may not carry the IP address, and after receiving the second message returned by the second terminal device, the first terminal device adds the virtual IP address to be identified by the network layer, where the destination IP address is the virtual IP address of the first terminal device, and the source virtual IP address is the virtual IP address of the second terminal device.

Fig. 14 is a schematic diagram of a message structure provided in an embodiment of the present application, and as shown in fig. 14 (a), in a standard Wi-Fi direct protocol, a packet header of a network layer includes an IP address, a packet header of a data link layer includes a MAC address, and an ethernet payload portion includes the IP address and an IP payload; as shown in fig. 14 (b), in this scheme, the unicast message includes the virtual IP addresses of the first terminal device and the second terminal device in the packet corresponding to the network layer, the header of the packet corresponding to the data link layer includes the MAC address, and the ethernet payload portion does not include IP address information.

For multicast messages, when terminal equipment sends the multicast messages, a multicast address can be added in an IP header of the multicast messages, wherein a destination IP address can be a multicast IP address, and a source IP address can be an appointed virtual IP address; optionally, the multicast message may also be similar to the unicast message, and the IP address is not carried when the multicast message is sent out. The setting method of the broadcast message is similar to the multicast message, and is not described herein again.

The terminal device may generate the virtual IP address according to the MAC address or other device information, for example, the terminal device may generate a local virtual IP address according to its own MAC address after the Wi-Fi direct connection function is started, and generate the virtual IP address of the peer device according to the MAC address of the peer device after the peer device is searched.

The beneficial effects of this solution are explained below: for the scenario shown in fig. 4, in the present solution, a1, B1, and C1 may set the same filtering condition (for example, input the same password), so that two of the three may establish Wi-Fi direct connection, and share resources with each other; similarly, a2, B2, C2 and D2 may also set the same filtering condition, and establish Wi-Fi direct connections with each other for resource sharing. The terminal devices communicate with each other through respective unique MAC addresses, and the virtual IP addresses are locally managed, so that the phenomenon of connection errors can be reduced, and the connection stability between the terminal devices is effectively improved.

For the scenario shown in fig. 5, the same filtering condition (for example, logging in the same system account) may be set between a3, B3, and C3, and a connection is established between two of them; if A3 left during the sharing process and D3 wished to join, on the one hand, the leaving of A3 did not affect the connection between B3 and C3 due to the peer-to-peer connection between A3, B3 and C3; on the other hand, D3 may search for B3 and C3 using the same filtering condition to establish connection with B3 and C3, and thus, data may be continuously shared among B3, C3, and D3, which further improves connection stability between terminal devices.

In addition, in the scheme, the connection process of the Wi-Fi direct connection is simplified, and the group establishment and the P2P invitation flow are cut off, so that the complexity of the Wi-Fi direct connection can be reduced, the resource requirement can be reduced, and the application range can be expanded; in addition, in the process of equipment discovery, the terminal equipment is searched and filtered through the filtering condition, so that irrelevant terminal equipment can be filtered, the searching efficiency and the safety are improved, and only the searched terminal equipment meeting the filtering condition is displayed on the interface, so that the operation interface can be optimized.

After the Wi-Fi direct connection is established between the first terminal device and the second terminal device, files can be shared mutually through the Wi-Fi direct connection, video calls can be conducted, cross-device editing can be conducted, wireless screen projection or remote control can be conducted, and the like. The following takes video call and file sharing as examples for illustration.

Carrying out video call based on Wi-Fi direct connection:

for example, in some areas where the mobile communication signal is weak or no mobile communication signal exists and no wireless local area network exists, such as a suburban area, the users cannot perform communication with each other with better quality, and at this time, the users can perform communication with each other through a video call function based on Wi-Fi direct connection on the terminal device.

Specifically, each user may establish a video call connection by using the video call process shown in fig. 9, and continue to use the password filtering as an example, as shown in (a) in fig. 15, after the user inputs the password "1122" and clicks the confirmation option 0031 for confirmation, the first terminal device starts to search for available Wi-Fi direct connection devices to establish a connection; assuming that the user of the second terminal device inputs the same password "1122" in the same manner, as shown in (b) of fig. 15, the first terminal device may establish a connection with the second terminal device and perform a video call through the connection, that is, transmit a collected video stream based on the established Wi-Fi direct connection.

The video call interface can provide hang-up options and convert into voice options and the like as shown in the figure; or under the condition that a plurality of second terminal devices are connected, displaying the video image acquired by one of the second terminal devices in the main window, and displaying the video images of other second terminal devices in the sub-window, so that the user can switch the video image displayed in the main window, wherein the size of the sub-window is smaller than that of the main window, and the sub-window can be displayed on the main window in a suspension manner.

For example: the user 1, the user 2 and the user 3 respectively establish video call connection with the terminal equipment of the other party through the password filtering mode, so that for each user, the terminal equipment (namely, the first terminal equipment) held by the user can display video images collected by the terminal equipment (namely, the second terminal equipment) held by the other two users; and one of the video images collected by the two second terminal devices is displayed in the main window, and the other video image is displayed in the sub-window. Assuming that the first terminal device shown in fig. 15 is a terminal device of the user 1, and the first terminal device establishes a video call connection with the terminal device held by the user 2 first, and then establishes a video call connection with the terminal device held by the user 3, as shown in (b) in fig. 15, a video image acquired by the terminal device held by the user 2 may be displayed on the first terminal device in a main window, and a video image acquired by the terminal device held by the user 3 in a sub-window; the user can click the sub-window to switch the video image displayed in the main window to the video image collected by the terminal device held by the user 3.

Of course, the first terminal device may also display a video image (not shown) acquired by the first terminal device in another sub-window, and the user may also click the sub-window to switch the video image displayed in the main window to the video image acquired by the first terminal device; the first terminal device may also display, by default, a video image acquired by the terminal device that has established the connection last in the main window, that is, the first terminal device may also display, by default, a video image acquired by the terminal device held by the user 3 in the main window.

It should be noted that the position and size of the main window and the sub-window in fig. 15 are only an example, and are not intended to limit the present application, and may be set as needed in specific implementation, which is not particularly limited in the present embodiment.

In some scenarios, if two users (e.g., user 1 and user 3) are too far away from each other and another user (e.g., user 2) is closer to the two users, the terminal devices of user 1 and user 3 cannot establish a Wi-Fi direct connection therebetween, and the terminal device of user 2 may establish a Wi-Fi direct connection with the terminal devices of user 1 and user 3, respectively, in which case, user 1 and user 3 may communicate with each other through the terminal device of user 2, that is, the terminal device of user 2 may serve as an intermediate device for communication, so as to implement long-distance communication.

The video call mode does not depend on base station signals, and carries out video call anytime and anywhere, so that the video call can be carried out in areas with weak mobile communication signals or no mobile communication signals by adopting the mode so as to better meet the requirements of users; in addition, the video call mode does not occupy the mobile data flow, so that the flow resource can be saved.

Sharing files based on Wi-Fi direct connection:

taking the terminal apparatus aaa shown in (b) in fig. 13 as an example, as shown in (a) in fig. 16, the user can select the terminal apparatus bbb desired to be accessed in the other apparatus column 501; as shown in (b) of fig. 16, after the user selects the terminal device bbb, the user can access the files on the terminal bbb, and edit and manage the files on the terminal bbb, wherein the accessible files may include the illustrated latest files, pictures, videos, audios, documents and other types of files, and the files under each type of files may include a plurality of folders, for example, as shown in the figure, the video files include all video folders, camera folders, screen recording folders, download folders, WeChat folders, QQ folders and the like.

Fig. 17 is a schematic view of file sharing provided in an embodiment of the present application, as shown in fig. 17 (a), a user may select a target picture S to be shared on a first terminal device, then click a sharing option 6, and open a sharing interface 60; as shown in fig. 17 (b), the sharing interface 60 may include other sharing icons such as a wechat icon 601, a Wi-Fi direct icon 602, a bluetooth icon 603, and a QQ icon 604, and the user may select the Wi-Fi direct icon 602 and open the Wi-Fi direct device selection interface 70; as shown in (c) of fig. 17, in the Wi-Fi direct device selection interface 70, the user may select a target device bbb from the connected second terminal device to share the target picture S with the selected target device bbb; as shown in (d) of fig. 17, after the user selects the target device bbb, the target device bbb may pop up a dialog box 80 asking whether the user receives, and the user may click on a reception option 801 in the dialog box 80 to receive the target picture S or click on a rejection option 802 to reject receiving the target picture S.

It can be understood that a user may also share a file with the first terminal device through the second terminal device, the shared file is not limited to a picture, and may also be a video, an audio, or a document and other types of files, for convenience of description, the picture is taken as an example in the following; in addition, when the target file to be shared is selected, other selection operations such as a click operation and a long-time press operation may be performed.

In order to improve the convenience of the user, an embodiment of the present application provides another file sharing method, which mainly determines a target device through an alignment operation, so that the user can share a file to an aligned terminal device quickly through a simple sharing operation.

It can be understood that after the first terminal device and the second terminal device are connected, the two terminals may share the file with each other, and for convenience of description, the file sharing from the first terminal device to the connected second terminal device is described as an example below.

In specific implementation, the first terminal device may detect a touch operation of a user on a target file, and if the touch operation is detected, may respond to the touch operation and share the target file with a target device in the connected second terminal device, where a pointing direction of the target device is opposite to a pointing direction of the first terminal device.

Referring to fig. 18, a specific process of the first terminal device sharing the target file with the target device may be shown, where fig. 18 is a schematic view of a file sharing process provided in the embodiment of the present application, and as shown in fig. 18, the process may include the following steps:

s210, the first terminal device responds to the sharing operation of the user on the selected target file and broadcasts a first notification message corresponding to the target file.

Specifically, the sharing operation may be a touch operation or a gesture operation, where the touch operation may be a screen sliding operation, such as a sliding operation on a target area of a screen (e.g., a top of the screen), or other predefined touch operations such as a continuous click operation; the gesture operation may be a slide gesture or other predefined gestures, which are not particularly limited in the embodiments of the present application. The target file may include one or more files that the user may select by clicking and/or long-pressing.

Fig. 19 is a schematic view of an application scenario of file sharing provided in the embodiment of the present application, as shown in fig. 19, the scenario includes a mobile phone a2100, a mobile phone B2200, a large-screen device 2300, and a pad2400, where the mobile phone a2100 represents a first terminal device, and Wi-Fi direct connection is respectively established with the mobile phone B2200, the large-screen device 2300, and the pad2400 (a second terminal device). As shown in fig. 19, a user may select a file on a mobile phone, align the mobile phone to a pad2400, and then share the file to the pad2400 through a sharing operation.

It can be understood that the user can also align the mobile phone a2100 with the large-screen device 2300 to share files with the large-screen device 2300; moreover, the mobile phone a2100, the mobile phone B2200, the large-screen device 2300, and the pad2400 may mutually discover each other, establish a Wi-Fi direct connection, and the user may also share a file to another connected terminal device through the pad2400 or the mobile phone B2200, where fig. 19 is only exemplarily illustrated by taking the case that the user shares the file to the pad2400 through the mobile phone a 2100. The following describes an interaction process between terminal devices by taking a scenario shown in fig. 19 as an example.

In a specific implementation, after the first terminal device detects the sharing operation of the user, a notification message (referred to as a first notification message) may be broadcast to notify the second terminal devices.

The first notification message may carry a file identifier of the target file, such as a file name (hereinafter, the file name is also used as an example for description), so as to notify the second terminal devices that the first terminal device is to share the target file.

The first notification message may also carry a pointing direction of the first terminal device, so as to identify the first notification message, for example: the user successively and continuously executes multiple sharing operations on the same target file, each sharing operation is directed at different second terminal equipment, the first terminal equipment correspondingly broadcasts multiple first notification messages, and the first notification messages can be distinguished through the pointing direction of the first terminal equipment carried in the first notification messages.

The first notification message may specifically be a broadcast message, and in order to save resources, the first notification message may also be a multicast message. Fig. 20 is a schematic view of address information of each message in file sharing according to an embodiment of the present application, and as shown in fig. 20, a destination MAC address in a first notification message may be a multicast MAC address, and a source MAC address is a MAC address of a mobile phone a.

And S220, the second terminal equipment returns a response message corresponding to the first notification message.

Specifically, after receiving the first notification message, each second terminal device may return a response message to the first terminal device.

The response message may carry a pointing direction of the corresponding second terminal device, so that the first terminal device determines a pointing relationship with the second terminal device. Wherein the pointing direction can be measured by a direction sensor.

The response message may also carry a file name, so that the first terminal device determines which first notification message the second terminal device replies to. For example, a user successively and continuously executes multiple sharing operations on a first terminal device to share different target files, the first terminal device correspondingly broadcasts multiple first notification messages, each second terminal device can respond to each first notification message after receiving each first notification message, and the response message carries a file name to inform the first terminal device of which first notification message the first terminal device responds.

In addition, the response message may also carry the pointing direction of the first terminal device to further identify the response message, for example, the user successively and continuously performs multiple sharing operations on the same target file, each sharing operation is directed to a different second terminal device, and the first terminal device correspondingly broadcasts multiple first notification messages; after receiving the first notification messages, the second terminal devices may respond to each first notification message, where the response message carries the file name and the pointing direction of the first terminal device, so as to inform the first terminal device which first notification message the first terminal device responds to.

In order to improve the accuracy of data sharing, if the target device may be located within a preset range (referred to as a first preset range) around the first terminal device, the response message may further carry a device location of the corresponding second terminal device, so that the first terminal device determines the target device based on the location, where the preset range may be a spherical area with the first terminal device as a center, that is, a distance between the target device and the first terminal device does not exceed a preset distance; the preset range may also be a cylindrical region centered on the first terminal device, i.e., the position of the target device relative to the first terminal device may be limited in the horizontal and vertical directions, respectively. The specific size of the preset range can be set as required, and this embodiment does not limit this specifically; the device location may be obtained through a Global Positioning System (GPS) module and/or a mapping application.

As shown in fig. 20, after the mobile phone B2200 receives the first notification message, the destination MAC address in the returned response message is the MAC address of the mobile phone a, and the source MAC address is the MAC address of the mobile phone B; after the large-screen device 2300 receives the first notification message, the destination MAC address in the returned response message is the MAC address of the mobile phone a, and the source MAC address is the MAC address of the large-screen device; after the pad2400 receives the first notification message, the destination MAC address in the returned response message is the MAC address of the mobile phone a, and the source MAC address is the MAC address of the pad.

And S230, after the first terminal equipment receives the response messages returned by the second terminal equipment, determining target equipment from the second terminal equipment according to the pointing direction of the first terminal equipment corresponding to the sharing operation and the pointing direction of the second terminal equipment in the response messages.

Specifically, after receiving the response message returned by each second terminal device, the first terminal device may determine the pointing relationship between the first terminal device and each second terminal device according to the pointing direction of the first terminal device when receiving the sharing operation of the target file by the user and the pointing direction of the second terminal device in the response message, and use the second terminal device opposite to the pointing direction of the first terminal device as the target device. The pointing direction of the first terminal device can be recorded when the sharing operation of the user on the target file is received, and if the response message carries the pointing direction of the first terminal device, the pointing relationship between the pointing direction of the first terminal device and the pointing direction of the second terminal device can be determined directly according to the pointing direction of the first terminal device and the pointing direction of the second terminal device in the response message.

If the response message carries the device location of the corresponding second terminal device, when the first terminal device determines the target device, in addition to the above-mentioned pointing relationship between the first terminal device and each second terminal device, the location relationship between the first terminal device and each second terminal device may also be determined according to the device location of the first terminal device and the device location of the second terminal device; and under the condition that the device position of the second terminal device is located in a preset range with the device position of the first terminal device as the center and the pointing direction is opposite to that of the first terminal device, determining the second terminal device as the target device. In order to improve the accuracy of the determined position relationship, the position relationship between the first terminal device and the second terminal device may be corrected by combining a ranging technique such as Round Trip Time (RTT) ranging.

When determining whether the pointing direction of the second terminal device is opposite to the pointing direction of the first terminal device, in order to improve the accuracy of the determination result, the determination may be performed in combination with the device positions of the first terminal device and the second terminal device. Fig. 21 is a schematic diagram of determining a location range of a target device according to an embodiment of the present application, and as shown in fig. 21, a point O is a device location of a first terminal device, and if a second terminal device is located on a pointing line of the first terminal device and a pointing direction of the second terminal device is consistent with a reverse direction of the pointing direction of the first terminal device, it may be considered that the pointing direction of the second terminal device is opposite to the pointing direction of the first terminal device, where the pointing line of the first terminal device extends along the pointing direction of the first terminal device with the device location of the first terminal device as a starting point.

For user convenience, a certain pointing error may be allowed when determining whether the pointing orientation of the second terminal device is opposite to the pointing orientation of the first terminal device. As shown in fig. 21, if the second terminal device is located in a preset range (referred to as a second preset range) with the pointing line of the first terminal device as a center line, and an orientation angle between the pointing direction and the opposite direction of the pointing direction of the first terminal device is within a preset angle range, the pointing direction of the second terminal device may be considered to be opposite to the pointing direction of the first terminal device. The second preset range may be a cylindrical area or a square columnar area, that is, the position of the target device relative to the pointing line of the first terminal device may be limited in the horizontal and vertical directions. The size of the second preset range and the size of the preset angle range may be set according to the requirement, which is not particularly limited in this embodiment. It should be noted that fig. 21 illustrates the position range of the target device in the horizontal direction as an example, and the position range in the vertical direction is not shown.

Continuing with fig. 19 as an example, for convenience of explanation, it is assumed that the device positions of the respective terminal devices are on the same horizontal plane, the preset angle range is 15 °, and the north orientation is 0 °. As shown in fig. 19, the pointing direction of the mobile phone a2100 is 30 ° (i.e., 30 °), the pointing direction of the mobile phone B2200 is 35 ° (i.e., 215 °), the pointing direction of the large-screen device 2300 is a true south direction (i.e., 180 °), the pointing direction of the pad2400 is 40 ° (i.e., 220 °), the large-screen devices 2300 and the pad2400 are located within a first preset range around the mobile phone a2100, the mobile phone B2200 is located outside the first preset range around the mobile phone a2100, the mobile phones B2200 and the pad2400 are located within a second preset range with the pointing line of the mobile phone a2100 as a center line, and the large-screen device 2300 is located outside the second preset range with the pointing line of the mobile phone a2100 as a center line. Wherein the first predetermined range is shown in the upper half and not in the lower half for simplicity.

Based on the above information, the pad2400 is located in a first preset range around the mobile phone a 2100; the reverse direction of the pointing direction of the mobile phone a2100 is 30 ° (210 °), an azimuth angle (10 °) between the pointing direction (220 °) of the pad2400 and the reverse direction (210 °) of the pointing direction of the mobile phone a2100 is smaller than a preset angle range (15 °), and the pad2400 is located in a second preset range with the pointing line of the mobile phone a2100 as a center line, so that the mobile phone a2100 can determine the pad2400 as a target device to share the picture a with the target device.

An azimuth angle (5 °) between the pointing direction (215 °) of the cell phone B2200 and the reverse direction (210 °) of the pointing direction of the cell phone a2100 is smaller than a preset angle range (15 °), and the cell phone B2200 is located within a second preset range with the pointing line of the cell phone a2100 as the center line, but the cell phone B2200 is located outside the first preset range around the cell phone a2100, and therefore, the cell phone B2200 is not determined as the target device of the cell phone a 2100.

The large-screen device 2300 is located within a first preset range around the cell phone a2100, however, the large-screen device 2300 is located outside a second preset range with the pointing line of the cell phone a2100 as the center line, and an azimuth angle (30 °) between the pointing direction (180 °) of the large-screen device 2300 and the reverse direction (210 °) of the pointing direction of the cell phone a2100 is larger than a preset angle range (15 °), and thus, the large-screen device 2300 is not determined as a target device of the cell phone a 2100.

It can be understood that the above target device determining process may also be executed in the second terminal device, that is, when the first terminal device sends the first notification message to the second terminal device, the first terminal device may carry the device position and the pointing direction of the first terminal device therein, and after receiving the first notification message, the second terminal device may determine whether the local terminal is the target device according to the location and the pointing direction, and then return the determination result to the first terminal device.

If the target device is not determined, the first terminal device may prompt the user that the target device is absent, where the prompt mode may be a text prompt or a voice prompt.

And S240, if the first terminal device determines the target device, sending a second notification message corresponding to the target file to the target device.

And if the first terminal equipment determines the target equipment, the first terminal equipment can share the target file with the target equipment. In order to save resources, the target device may first check whether the target file is stored locally, and then request resources from the first terminal device if the target file is not stored.

In specific implementation, after the target device is determined, the first terminal device may send a notification message (referred to as a second notification message) to the target device, where the second notification message may carry a file name of the target file to notify the target device of the target file to be shared, so that the target device may perform subsequent viewing operation.

And S250, if the target device receives the second notification message, checking whether the target file is stored or not.

After receiving the second notification message, the target device may check whether the target file is stored locally according to the file name carried in the second notification message.

If the target equipment determines that the target file is locally stored, the target file can be loaded and displayed for a user to view; or prompt information can be displayed to prompt the user that the target file to be shared by the first terminal device is stored locally.

And S260, if the target device determines that the target file is not stored, sending a resource request message corresponding to the target file to the first terminal device.

If the target device determines that the target file is not stored locally, the target device may send a resource request message to the first terminal device to request the first terminal device to transmit the target file. The resource request message may carry a file name of the target file, so that the first terminal device can identify the target file to be sent.

Optionally, the target device may ask the user whether to receive the target file as a pop-up dialog box shown in (d) of fig. 17, so as to facilitate user operation, the target device may not pop-up the dialog box, and the user may not align the second terminal device with the first terminal device if the user does not want to receive the target file, so that the scheme may also be directly applied to other terminal devices which are not convenient for user operation, such as a large-screen device, and the like, thereby expanding the applicable range of file sharing and unifying file sharing schemes among various terminal devices.

And S270, after receiving the resource request message, the first terminal device sends the target file to the target device.

S280, the target device receives the target file.

As shown in (a) in fig. 22, after the user opens a picture a, the picture is shared to the aligned pad2400 by a slide-up operation on the top of the screen; as shown in fig. 22 (b), after the pad2400 receives the picture a, the picture a may be loaded and displayed for the user to view; of course, the pad2400 may also display a prompt message to prompt the user that the target file has been received.

Fig. 23 is a schematic view of another file sharing provided in the embodiment of the present application, which is illustrated by taking an example in which a mobile phone a2100 shares multiple pictures (target files) to a pad2400 (target device). As shown in fig. 23 (a), after opening the picture selection interface by a long-press operation, the user clicks and selects the picture a, the picture B, and the picture C, and then shares the pictures to the aligned pad2400 by a slide-up operation on the top of the screen; as shown in fig. 23 (B), after the pad receives the picture a, the picture B, and the picture C, a last received picture, such as the picture C, may be loaded and displayed for the user to view; similarly, the pad2400 may display a prompt to prompt the user that the target file has been received.
