Detailed ways

The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. The terms used in the implementation part of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

First, the application scenarios of the embodiments of the present application are introduced. The technical solutions provided in the embodiments of the present application may be applicable to various Wi-Fi P2P connection scenarios. For the convenience of description, the Wi-Fi direct connection scenario is used as an example for illustrative description in this embodiment.

FIG. 1 is a schematic diagram of a system architecture of a wireless communication method provided by an embodiment of the present application. As shown in FIG. 1 , the system may include multiple terminal devices (three are used as an example in the figure for illustration), and each terminal device Wi-Fi direct connection can be established between them, and data can be shared with each other through the established connection. The terminal device may be a mobile phone 1100, a tablet computer (pad) 1200, a TV 1300 shown in FIG. 1, or a large-screen device, a desktop computer, a notebook, or a wearable device that is not shown that supports Wi-Fi Direct connected terminal equipment.

Specifically, a standard Wi-Fi direct connection technology can be used to establish a wireless connection between terminal devices, that is, a group can be established between terminal devices. In the group, one of the terminal devices acts as a group owner. , GO), other terminal devices act as group clients (GC), and a Wi-Fi direct connection is established between GO and each GC.

Among them, the connection establishment process between the GO and any GC may include processes such as device discovery and group formation. The two devices discover each other through the device discovery process, and the GO negotiation and Exchange security configuration information.

FIG. 2 is a schematic diagram of an application interface provided by an embodiment of the present application. As shown in (a) of FIG. 2 , the user can click the Wi-Fi direct connection option 101 in the Wi-Fi setting interface 10 Fi Direct interface 20, activate the Wi-Fi Direct function. After the Wi-Fi Direct function is activated, the terminal device will initiate a device discovery process to search for Wi-Fi Direct devices around, as shown in (b) in Figure 2, the available device bar 202 can display "Searching", etc. A message prompts the user to search for available Wi-Fi Direct devices. Among them, in the Wi-Fi direct connection interface 20, the user can edit the name of the Wi-Fi direct connection device of the local end through the device name option 2011 in the my device bar 201, as shown in FIG. 2, the Wi-Fi of the mobile phone 1100 The name of the directly connected device is "AAA".

The following takes two terminal devices (respectively a first terminal device and a second terminal device) as an example to describe the Wi-Fi Direct connection establishment process.

FIG. 3 is a schematic flowchart of a device discovery process provided by an embodiment of the present application. As shown in FIG. 3 , the device discovery process may include: a scan phase (scan phase) and a discovery phase (find phase).

Scanning phase: After the device discovery process is started, the terminal device (including the first terminal device and the second terminal device) will first enter the scanning phase. In this phase, the terminal device sends a probe request (Probe Request) on all frequency bands it supports. ) frame, the terminal device does not process the probe request frame from other devices in this stage, it can receive the probe response (Probe Response) frame, and find other terminal devices in the listening state.

Discovery phase: After the scanning phase is completed, the terminal device enters the discovery phase. During this phase, the end device switches back and forth between the listen state and the search state.

In the listening state, the terminal device randomly selects a frequency band in the

frequency bands

1, 6 and 11 (that is, ch1, ch6 and ch11 in the figure, called social channel) as the listening frequency band (listen channel), and monitors the detection request. frame and reply to the probe response frame accordingly. For example, in FIG. 2 , the monitoring frequency band of the first terminal device is 1, and the monitoring frequency band of the second terminal device is 6. The terminal device enters the search state after listening for a period of time.

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

frequency bands

1, 6 and 11 respectively. When two terminal devices are in the same frequency band, the frame sent by one party can be received by the other party. For example, in Figure 2, the second terminal device monitors the probe request frame sent by the first terminal device on ch6 on ch6, and sends the frame to the first terminal device on ch6. A terminal device replies with a probe response frame accordingly.

After the terminal device completes the interaction between the probe request frame and the probe response frame, that is, it discovers the Wi-Fi Direct device, and can store the device information of the peer device, including the media access control (MAC) address, device type (device type) ) and device name, etc.

As shown in (c) in Figure 2, once the terminal device searches for a Wi-Fi Direct device, it will update the interface to display the searched Wi-Fi Direct device. BBB" (the device name of the pad 1200) and "CCC" (the device name of the TV 1300). The user can select a Wi-Fi Direct device in this interface to establish a connection with it. For example, as shown in (c) and (d) in Figure 2, the user can click "BBB" to establish a connection with it.

After the user selects the Wi-Fi Direct device to be connected, the terminal device can carry out a group establishment process (starting to establish a group in the corresponding figure) to prepare to construct a Group, and the process can include GO negotiation (GO negotiation, GON) Process and security provisioning process. Among them, the GON process is used to negotiate who will do the GO. After the GON process is executed, the security configuration process is performed. This process mainly uses the Wi-Fi simple configuration (WSC) protocol to negotiate security configuration information.

After the group establishment process is over, the GC applies to the GO for an internet protocol (IP) address, and the GO starts a dynamic host configuration protocol (DHCP) server to assign an IP address to the GC. , the terminal device can update the connection status and inform the user that the connection is successful. For example, as shown in (d) in FIG. 2 , the connection status of the updated "BBB" is "connected". After the group is disbanded, the IP address of the GC can be released.

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

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

According to the Wi-Fi Direct connection protocol, the default IP address of GO is 192.168.49.1, that is, the IP address of GO in any group is 192.168.49.1, so the IP addresses of GO in different groups overlap and may interfere with each other, thus A condition that causes an unstable connection to the end device. FIG. 4 is a schematic diagram 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, and A1 and A2 are respectively The GO of the respective group, the default IP address of both is 192.168.49.1. In a relatively small space (such as in the same subway car), two groups want to share data such as audio, video or pictures at the same time; during the communication process, since the IP addresses of A1 and A2 are the same, each GC: B1, C1, B2, C2 and D2 cannot automatically determine which GO is connected, nor can they manually intervene; and after connecting the wrong GO, even if the wrong GO leaves, the GC still needs a long time to restore the initial state and reconnect the new GO , which will affect the connection stability of the terminal device.

In addition, the address of the GC is dynamically allocated by GO, which may also affect the connection stability of the terminal device. FIG. 5 is a schematic diagram of another application scenario provided by the embodiment of the present application. As shown in FIG. 5 , A3, B3 and C3 are a group, and the three share data with each other, wherein A3 is GO; during the sharing process, A3 leaves , D3 wants to join the group. Since A3 is a GO, after it leaves, the group is disbanded, B3 and C3 cannot continue to share data, and D3 cannot obtain an IP address in time, so it cannot participate in data sharing. B3, C3 and D3 need to re-share Form a group to continue sharing data.

In addition, the device discovery, negotiation and connection process in the Wi-Fi Direct protocol is complex, requires too many resources, and has high system overhead, which is too heavy for thin devices; All the surrounding terminal devices are in the device discovery state, so the search efficiency is low, and the operation interface corresponding to the search results is not simple enough, and if irrelevant terminal devices are searched and connected by mistake, there may be security risks.

To this end, the embodiments of the present application provide a lightweight wireless communication method, which mainly simplifies the Wi-Fi direct connection protocol and process, cuts out the group establishment and P2P invitation process, and adopts a decentralized method for group management. , that is, peer-to-peer connection of devices at both ends, cancel the role distinction between GO and GC; and IP address management can also be decentralized, cancel the unified management and allocation of GC IP addresses, virtualize IP addresses, and locally manage this by terminal devices. The virtual IP address of the end and the opposite end, the data is forwarded by the data link layer to solve the problem that the IP address of the GO overlaps and the automatic connection of the terminal device is unstable; in addition, during the device discovery process, the terminal device is searched and filtered to Improve search efficiency and security, and optimize the operation interface. The technical solution will be described in detail below.

FIG. 6 is a schematic flowchart of a wireless communication method provided by an embodiment of the present application. As shown in FIG. 6 , the wireless communication method provided by this embodiment may include the following steps:

S110. The first terminal device searches for a second terminal device that satisfies the filter condition of the local end in response to the user's connection triggering operation.

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

Specifically, the user can enable the Wi-Fi Direct function through a connection trigger operation, where the connection trigger operation can be a user trigger operation on the target system function. For example, the user can, as shown in (a) of FIG. 2, Click the Wi-Fi direct connection option in the Wi-Fi setting interface to enable the Wi-Fi direct connection function; as another implementation method, the first terminal device can also provide shortcut options, such as shown in Figure 7, which can be found in A Wi-Fi direct connection icon is provided in the pull-down notification bar, and users can click the icon to enable the Wi-Fi direct connection function. Among them, the Wi-Fi direct connection function can only be turned on when the Wi-Fi function is turned on. Therefore, when receiving a connection trigger operation from the user, the terminal device can automatically turn on the Wi-Fi function when the Wi-Fi function is not turned on. After the Wi-Fi function is enabled, the Wi-Fi direct connection function is enabled; the user may also be prompted to enable the Wi-Fi direct connection function after the user authorizes the Wi-Fi function to be enabled.

In order to improve user convenience, in this embodiment, when the user starts a target application (application, APP) or target function, the target APP or target function is triggered to automatically enable the Wi-Fi direct connection function. For example, after the user clicks the gallery icon to open the gallery, the gallery automatically enables the Wi-Fi direct connection function; for another example, when the user clicks the video call function to initiate a video call, the video call function automatically enables the Wi-Fi direct connection function to search for available Wi-Fi -Fi Direct device to establish connection.

It can be understood that the target application is not limited to the above-mentioned gallery, and may also be a file management APP or other instant messaging APP, etc., which is not particularly limited in this embodiment of the present application.

Certainly, the user may enable the Wi-Fi direct connection function by inputting a voice command, which is not particularly limited in this embodiment. In addition, the connection trigger operation may also be a click operation of the 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 the first terminal device detects the user's connection triggering operation, it can respond to the operation and enter the device discovery process to filter and search to search for the second terminal device that satisfies the filter conditions of the local end, where the filter conditions can be preset by the system For example, the first terminal device automatically searches for the second terminal device that is logged into the same system account; in order to improve the flexibility of the user, the first terminal device may also provide a filter condition setting function for the user to independently set the filter condition.

During specific implementation, as shown in (a) of FIG. 8 , in addition to the various functional options shown in FIG. 2 , the Wi-Fi Direct interface 20 may also include a filter condition option 203 , and the user can click The filter condition option 203 opens the filter condition interface 40; as shown in (b) of FIG.

Specifically, as shown in (b) in FIG. 8 , the filtering conditions may include system account filtering, group filtering, password filtering, voice filtering, and near field communication (NFC) filtering, etc. In the filtering condition interface 40 Switch controls 401 to 405 corresponding to each filter condition may be provided, and the user may select to enable one or more filter conditions through these switch controls, that is, the filter conditions may include one or more.

For system account filtering, if enabled by the user, the first terminal device can automatically search for a second terminal device that logs into the same system account as the first terminal device during the search process. Optionally, the embodiment of the present application is not limited to filtering system accounts, and other accounts may also be filtered during specific implementation.

For group filtering, if the user has pre-established target groups, such as family group (including information about terminal equipment of all family members) and adult group (excluding information about terminal equipment held by minors in family members) , you can also enable group filtering and add group filtering conditions when performing terminal search filtering. Among them, as shown in the figure, the group name editing option 4021 can be set in the column where the group filtering option is located, so that the user can edit the specific conditions of the group filtering. Optionally, the specific conditions of the group filtering can also be the group number. and other group identification information, which is not particularly limited in this embodiment of the present application. If group filtering is enabled, the first terminal device can automatically search for the second terminal device in the target group selected by the user during the search process. For example, the user sets the group name in the group filter to be a family group, and the first terminal device searches the terminal devices (ie, the second terminal device) of each member in the family group.

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

For voice filtering, if enabled by the user, the first terminal device can automatically collect the voice information input by the user after the Wi-Fi direct connection function is enabled, generate filtering information according to the collected voice information, and then automatically search for detection during the search process. The second terminal device carrying the same filtering information in the message. For this filter condition, in the specific application, due to the short distance between terminal devices, any user around the terminal device can send voice information, and each terminal device can collect the voice information, and generate a filter based on the voice information. Filter information corresponding to the condition.

For NFC filtering, after enabling the Wi-Fi direct connection function of the first terminal device, the user can perform a "touch" operation between the first terminal device and the second terminal device that needs to establish a connection; the first terminal device can collect to the NFC information of the second terminal device (for example, it may be an NFC identifier), and then the second terminal device corresponding to the collected NFC information can be searched during the search process. During specific implementation, the first terminal device may generate filtering information according to the NFC information of the local end and the collected NFC information.

It can be understood that, if the user does not enable any filtering conditions, the first terminal device can also perform processes such as device discovery and negotiation according to the standard Wi-Fi Direct protocol to establish a connection.

As another implementation manner, the first terminal device may provide filtering functions corresponding to the above-mentioned various filtering conditions for the target application to invoke, and the target application automatically enables at least one filtering function after enabling the Wi-Fi Direct function, for example , after the user opens the gallery, the gallery activates the system account filtering function while enabling the Wi-Fi direct connection function, and searches for the second terminal device logged in the same system account; for another example, after the user enables the video call function, he can input voice to initiate a video For calls and video calls, when the Wi-Fi direct connection function is enabled, the voice filter function is activated, and the voice input by the user is used as a filter condition to filter and search; alternatively, the target APP or target function can also provide the activation option of the filter function The user can activate the corresponding filtering function by clicking the activation option. The following takes the target function as the video calling function as an example to illustrate the process of enabling the Wi-Fi direct connection function and the filtering function of the user.

FIG. 9 is a schematic diagram of some application interfaces provided by the embodiments of the present application. As shown in (a) of FIG. 9 , a video call icon 3012 can be provided in the pull-down notification bar, and the user can click the icon to enable the video call function. After the video call function is turned on, the Wi-Fi direct connection function can be automatically turned on as described above, or as shown in (b) in Figure 9, the user can be prompted to authorize the Wi-Fi direct connection function and the Wi-Fi function to be turned on. . The user can select the enable option to enable the Wi-Fi direct connection function and the Wi-Fi function, as shown in (c) in Figure 9, after the Wi-Fi direct connection function is enabled, the video call function can provide various filters corresponding to the filter function Conditional startup options: system account filtering option 001, group filtering option 002, password filtering option 003, voice filtering option 004, and NFC filtering option 005, wherein, for the system account filtering option 001, after the user clicks, the first terminal device is It can search for available Wi-Fi direct devices to establish a connection; for group filter option 002 and password filter option 003, after the user selects, the video call function can provide an input interface for users to enter group information or password information; for voice filter option 004 and NFC filter option 005, after the user selects, the first terminal device may prompt the user to input voice information or perform a "tap" operation. Taking password filtering as an example, as shown in (c) and (d) in Figure 9, the user can click the password filtering option 003, and then enter a password in the pop-up input interface, where the number of digits of the password can be as shown in the figure The default is 4 bits, and the number of bits is not limited.

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

The search process of the first terminal device and the second terminal device will be described in detail below.

As described above, the first terminal device may carry the filtering information corresponding to the filtering conditions in the detection message, and the detection message may include a detection request message and a detection request response message, wherein the detection request message may specifically be a detection request frame, and the detection request response The message may specifically be a probe response frame, that is, the first terminal device may carry filter information in the probe request frame and the probe response frame; the filter information may be the system account number, group ID, password, voice information or NFC information in the above filter conditions In order to improve the security of data transmission, the filtering information may also be character information generated according to the above-mentioned information such as system account number, group identification, password, voice information or NFC information. Correspondingly, when the first terminal device and the second terminal device search each other for each other, the method shown in FIG. 10 can be used to realize. FIG. 10 is a schematic flowchart of filtering and searching provided by this embodiment of the application. The method may include the following steps:

S111. The first terminal device broadcasts a probe request frame carrying the first filtering information.

Specifically, the filter condition may also be set in the second terminal device, and the specific setting process is similar to the filter condition setting process of the first terminal device, which will not be repeated here. For convenience of distinction, the filtering information corresponding to the filtering condition in the first terminal device is referred to as the first filtering information, and the filtering information corresponding to the filtering condition in the second terminal device is referred to as the second filtering information.

After the Wi-Fi direct connection function is enabled, the first terminal device may broadcast the probe request frame on all channels or social channels as described above. In order to facilitate the peer device to know the filter conditions of the first terminal device, the first terminal device may carry the first filter information in the probe request frame, so that the second terminal device can reply with a response message when the filter conditions are satisfied, so as to Inform the first terminal device that it meets the filtering conditions.

FIG. 11 is a schematic diagram of a frame structure of a probe request frame and a probe response frame provided by an embodiment of the application. As shown in FIG. 11 , the probe request frame may include a MAC header, a frame body, and a frame check. The sequence (frame check sequence, FCS) field, in which the MAC frame header may include some frame control information and address information, etc.; the frame body represents the data field, which is the payload; FCS is used to ensure the integrity of the frame data.

The first filtering information may be carried in the frame body. In the specific implementation, a characteristic parameter (character code) field may be added to the frame body, and the first filtering information may be indicated by this field, wherein the characteristic parameter field may be located in any arbitrary position of the frame body. Location.

S112. After receiving the probe request frame, the second terminal device determines whether the first filter information carried in the probe request frame matches the second filter information, and if so, it is determined that the first terminal device satisfies the local filter condition.

The second terminal device may be similar to the first terminal device, and responds to the user's connection triggering operation to enable the Wi-Fi direct connection function. The specific process is similar to that of the first terminal device to enable the Wi-Fi direct connection function, which will not be repeated here. .

After enabling the Wi-Fi direct connection function, the second terminal device may monitor the probe request frame on the monitor frequency band as described above. If the second terminal device monitors the detection request frame, it can extract the first filter information in it, compare it with the filter information corresponding to the filter conditions of the local end (ie the second filter information), and determine whether the first terminal device complies with the local end's filter information. filter conditions. If the first filtering information matches the second filtering information, it means that the first terminal device complies with the filtering conditions of the second terminal device; if the first filtering information does not match the second filtering information, the second terminal device can discard the detection request frame, refusing to connect with the first terminal device.

When making a specific judgment, for filter conditions such as account number, group, password, and NFC, it is possible to compare whether the first filtering information is consistent with the second filtering information. If they are consistent, the two are considered to match; for voice filtering, the The similarity between the first filtering information and the second filtering information, if the similarity meets the preset similarity, it can be considered that the two match, wherein the size of the preset similarity can be set according to actual needs.

S113. The second terminal device returns a probe response frame carrying the second filtering information to the first terminal device.

If the second terminal device determines that the first filter information carried in the probe request frame matches the second filter information, it may reply to the probe response frame accordingly to inform the first terminal device that the two filter conditions are consistent, that is, the first terminal device and the The second terminal devices meet the filtering conditions of the peer end. Alternatively, confirmation information may also be carried in the probe response frame to inform the first terminal device that the filtering conditions of the two are consistent.

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

As shown in Figure 11, the probe response frame may include MAC frame header, frame body and FCS fields. Similar to the first filter information, the second filter information may be carried in the frame body of the probe response frame. Similarly, the probe response frame may contain the second filter information. A feature parameter field is added to the frame body of the frame, through which the second filtering information is indicated, wherein the feature parameter field can be located at any position in the frame body.

It can be understood that the probe request frame and the probe response frame may also carry device information such as the device identification, device name, device type, and MAC address of the local device for identification by the peer device.

S114: After receiving the probe response frame, the first terminal device determines whether the second filter information carried in the probe response frame matches the first filter information, and if so, determines that the second terminal device satisfies the local filter condition.

Specifically, after receiving the probe response frame replied by the second terminal device, the first terminal device may determine that the second terminal device satisfies the filtering conditions of the local end.

As mentioned above, in order to improve reliability, the probe response frame can carry the second filter information, and correspondingly, the first terminal device can extract the second filter information, the filter information corresponding to the filter conditions of the local end (that is, the first terminal device). filter information) to compare, and based on the comparison result, determine whether the second terminal device complies with the filtering conditions of the local end.

Specifically, if the first filtering information matches the second filtering information, it means that the second terminal device complies with the filtering conditions of the first terminal device; if the first filtering information does not match the second filtering information, it means that the second terminal device does not match. If the filtering conditions of the first terminal device are met, 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 judging whether the first filter information matches the second filter information is similar to the process of judging the filter information by the second terminal device, and details are not described herein again.

In the near field communication scenario, the two communicating parties are in the same local area network and can communicate with each other directly through the physical layer and the data link layer. Therefore, in this embodiment, when data transmission is performed between terminal devices, the data packets may not be included in the data packets. Carrying the IP address, it communicates through the physical layer and the data link layer. Correspondingly, the IP address allocation process can be cut out, and then the group establishment process and the P2P invitation process can be cut out. In this way, when the first terminal device searches for a second terminal device that satisfies the filtering conditions, it can indicate that the connection is established successfully, and the Wi-Fi Direct connection status of the searched second terminal device can be displayed as a connected state. Similarly, The Wi-Fi Direct connection status of the first terminal device may also be displayed as a connected state on the searched second terminal device. Wherein, the second terminal device searched by the first terminal device may include one or more.

It can be understood that the first terminal device and the second terminal device are only for the purpose of distinguishing the description. For a certain terminal device, it can be used as the first terminal device or as the second terminal device, that is, the first terminal device and the second terminal device. Both terminal devices can have the functions of each other. For example, for the first terminal device, it can also receive probe request frames broadcast by other terminal devices (referred to as third terminal devices). If the information matches, it can be determined that the third terminal device satisfies the filtering conditions of the local end, and can return a probe response frame carrying the first filtering information to the third terminal device; correspondingly, the third terminal device can judge its own filtering information. When matching with the first filtering information in the probe response frame, it is determined that the first terminal device satisfies the filtering condition of the third terminal device. That is, any terminal device can use the search process performed by the first terminal device shown in FIG. 10 and/or the search process performed by the second terminal device to establish a Wi-Fi direct connection with other terminal devices.

Take three terminal devices aaa, bbb, and ccc to search for each other to establish a connection as an example. Assuming that aaa and bbb have the same filter conditions, they both log in to the same system account, and the system account logged in by ccc is different from that of aaa and bbb. As shown in (a) of Figure 12, the user clicks the Wi-Fi Direct option of the three terminal devices to activate the Wi-Fi Direct function; as shown in (b) of Figure 12, the three terminal devices start Search for available Wi-Fi direct devices around, as shown in (c) in Figure 12, aaa and bbb can search for each other to establish a connection, ccc does not meet the filter conditions of aaa and bbb, in the search process of aaa and bbb is filtered out, it cannot establish a connection with aaa and bbb.

As shown in (a) of Figure 13, the user can also click the file management icon 5 of the three terminal devices to open the file management APP, and the file management APP automatically starts the Wi-Fi direct connection function; aaa and bbb can be based on the same The system accounts (filtered information) of the 2s can search each other to establish a connection, and ccc cannot establish a connection with aaa and bbb. As shown in (b) of FIG. 13 , the user can view the connected Wi-Fi Direct devices in the other device bar 501 of the file management interface 50 corresponding to the file management icon 5, wherein the user can click the file management interface The browse icon 502 of 50 opens the browse interface to browse files on the local computer and other devices. The other device bar 501 can be located in the browse interface; the file management interface 50 can also provide other functional controls such as a search box.

In order to be compatible with upper-layer applications such as the network layer, the first terminal device and the second terminal device can locally generate virtual IP addresses for both parties, where the virtual IP address is only valid locally, and when data transmission is performed, the first message sent to the outside The IP address may not be carried in the message. After receiving the first message, the second terminal device may add the virtual IP address to the data packet transmitted to the network layer for identification by the network layer, wherein the destination IP address is the second message. The virtual IP address of the 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 the first After receiving the second message returned by the second terminal device, a terminal device adds a virtual IP address for identification by the network layer, wherein the destination IP address is the virtual IP address of the first terminal device, and the source virtual IP address is the first virtual IP address. 2. The virtual IP address of the terminal device.

FIG. 14 is a schematic diagram of a message structure provided by an embodiment of the present application. As shown in (a) of FIG. 14 , in the standard Wi-Fi Direct protocol, the data packet header of the network layer includes an IP address, and the data of the data link layer The packet header contains the MAC address, and the Ethernet payload part contains the IP address and the IP payload; as shown in (b) in Figure 14, in this solution, the above-mentioned unicast message contains the first terminal device in the data packet corresponding to the network layer and the virtual IP address of the second terminal device, the header of the data packet corresponding to the data link layer contains the MAC address, and the Ethernet payload part does not contain IP address information.

For a multicast message, the terminal device can add a multicast address to the IP header of the multicast message when sending, where the destination IP address can be the multicast IP address, and the source IP address can be the agreed virtual IP address; optional Yes, multicast messages can also be similar to unicast messages, and do not carry an IP address when sent out. The setting method of the broadcast message is similar to that of the multicast message, and will not be repeated here.

The terminal device can generate a virtual IP address according to the MAC address or other device information. For example, the terminal device can generate its own virtual IP address according to its own MAC address after the Wi-Fi Direct function is activated. Afterwards, the virtual IP address of the peer device is generated according to the MAC address of the peer device.

The beneficial effects of this scheme are described below: For the scenario shown in Figure 4, in this scheme, A1, B1 and C1 can set the same filter condition (for example, enter the same password), so that Wi-Fi can be established between each of the three Fi direct connection to share resources with each other; similarly, A2, B2, C2 and D2 can also set the same filter conditions to establish Wi-Fi direct connection with each other for resource sharing. Each terminal device communicates with each other through their own unique MAC addresses, and the virtual IP address is managed locally, thus reducing the phenomenon of connection errors and effectively improving the connection stability between the terminal devices.

For the scenario shown in Figure 5, A3, B3 and C3 can set the same filter condition (for example, log in to the same system account), and establish a connection between them; if A3 leaves during the sharing process, D3 wants to join, on the one hand , due to the peer-to-peer connection between A3, B3 and C3, the departure of A3 does not affect the connection between B3 and C3; on the other hand, D3 can use the same filter conditions to search for B3 and C3, and establish a connection with B3 and C3, Therefore, data can continue to be shared among B3, C3 and D3, which further improves the connection stability between terminal devices.

In addition, in this solution, the connection process of Wi-Fi direct connection is simplified, and the group establishment and P2P invitation process are cut out, thus reducing the complexity of Wi-Fi direct connection, thereby reducing resource requirements and expanding Scope of application; in addition, in the process of device discovery, terminal devices are searched and filtered through filter conditions, which can filter out irrelevant terminal devices, improve search efficiency and security, and only display the searched ones that meet the filter conditions on the interface. terminal equipment, thus also optimizing the operator interface.

After the first terminal device and the second terminal device establish a Wi-Fi direct connection, they can share files with each other, make video calls, edit across devices, wirelessly cast a screen, or remotely control each other through the Wi-Fi direct connection. The following is an exemplary description by taking video calls and file sharing as examples.

To make a video call over a Wi-Fi Direct connection:

For example, in some areas with weak or no mobile communication signal and no wireless local area network, such as suburban areas, users cannot communicate with better quality. The connected video calling features communicate with each other.

Specifically, each user can use the video call process shown in Figure 9 to establish a video call connection, and continue to take password filtering as an example, as shown in (a) in Figure 15, after the user enters the password "1122" and clicks After the confirmation option 0031 is confirmed, the first terminal device starts to search for available Wi-Fi Direct devices to establish a connection; it is assumed that the user of the second terminal device inputs the same password "1122" in the same way, as shown in Figure 15 ( As shown in b), the first terminal device can establish a connection with the second terminal device, and conduct a video call through the connection, that is, transmit the collected video stream based on the established Wi-Fi direct connection.

Among them, the video call interface can provide the option of hanging up and switching to voice as shown in the figure; or when multiple second terminal devices are connected, the main window can display the data collected by one of the second terminal devices. and display the video images of other second terminal devices in the sub-window, so that the user can switch the video images displayed in the main window, wherein the size of the sub-window is smaller than that of the main window, and it can be suspended on the main window show.

For example, if user 1, user 2 and user 3 respectively establish a video call connection with each other's terminal equipment through the above-mentioned password filtering method, then for each user, the terminal equipment (ie the first terminal equipment) held by each user can display another Video images collected by terminal devices (ie, second terminal devices) held by two users; among the video images collected by the two second terminal devices, one is displayed in the main window, and the other is displayed in the sub-window. Assuming that the first terminal device shown in FIG. 15 is the terminal device of user 1, the first terminal device first establishes a video call connection with the terminal device held by user 2, and then establishes a video call connection with the terminal device held by user 3, Then as shown in (b) in Figure 15, the first terminal device can display the video image collected by the terminal device held by user 2 in the main window, and the video image collected by the terminal device held by user 3 in the sub-window; 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 user 3 .

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

It should be noted that the positions and sizes of the main window and the sub-windows in FIG. 15 above are just examples, which are not used to limit the present application, and can be set as required during specific implementation, which is not particularly limited in this embodiment.

In some scenarios, if two users (eg, user 1 and user 3) are too far apart, and another user (eg, user 2) is close to the two users, then user 1 and user 3 A Wi-Fi direct connection cannot be established between the terminal devices of user 2, and the terminal device of user 2 can establish a Wi-Fi direct connection with the terminal devices of user 1 and user 3 respectively. In this case, user 1 and user 3 can The communication is performed through the terminal device of the user 2, that is, the terminal device of the user 2 can be used as an intermediate device for communication, so as to realize long-distance communication.

The above video call method does not rely on base station signals, and can make video calls anytime and anywhere. Therefore, in some areas with weak or no mobile communication signals, the above methods can be used to make video calls to better meet user needs; The video call method does not occupy mobile data traffic, so it can also save traffic resources.

File sharing over Wi-Fi Direct connection:

Taking the terminal device aaa shown in (b) in FIG. 13 as an example, as shown in (a) in FIG. 16 , the user can select the terminal device bbb that he wants to access in the other device column 501; as shown in FIG. 16 As shown in (b), after the user selects the terminal device bbb, he 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 latest files, pictures, videos, Audio, document and other types of files, the files under each type of file can include multiple folders, for example, as shown in the figure, video files include all video folders, camera folders, screen recording folders, download folders, WeChat folder and QQ folder, etc.

FIG. 17 is a schematic diagram of a file sharing provided by an embodiment of the present application. As shown in (a) of FIG. 17 , the user can select the target image S to be shared on the first terminal device, and then click the sharing option 6 to open the sharing Interface 60; as shown in (b) of FIG. 17, the sharing interface 60 may include other sharing icons such as WeChat icon 601, Wi-Fi Direct icon 602, Bluetooth icon 603, and QQ icon 604, and the user can select Wi-Fi Direct Connect icon 602, 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 can select a target from the connected second terminal device device bbb to share the target image S to the selected target device bbb; as shown in (d) of FIG. 17 , after the user selects the target device bbb, the target device bbb can pop up a dialog box 80 asking the user whether to accept it. The accept option 801 in the dialog box 80 may be clicked to accept the target picture S, or the reject option 802 may be clicked to reject the reception of the target picture S.

It can be understood that the user can also share files with the first terminal device through the second terminal device. The shared files are not limited to pictures, but can also be other types of files such as video, audio or documents. An exemplary description is given as an example; in addition, when selecting a target file to be shared, it may be a click operation, or other selection operations such as a long press operation.

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

It can be understood that after the first terminal device and the second terminal device establish a connection, the two parties can share files with each other. For the convenience of description, the first terminal device shares files with the connected second terminal device as an example for description.

During specific implementation, the first terminal device can detect the user's touch operation on the target file, and if the operation is detected, it can respond to the operation and share the target file with the target device in the connected second terminal device, wherein, The pointing orientation of the target device is opposite to the pointing orientation of the first terminal device.

The specific process of the first terminal device sharing the target file with the target device may refer to FIG. 18 . FIG. 18 is a schematic diagram of a file sharing process provided by this embodiment of the present application. As shown in FIG. 18 , the process may include the following steps:

S210. In response to the user's sharing operation on the selected target file, the first terminal device broadcasts a first notification message corresponding to the target file.

Specifically, the sharing operation may be a touch operation or a gesture operation, wherein the touch operation may be a screen sliding operation, such as an upward sliding operation on a target area of the screen (such as the top of the screen), or other predefined operations such as a combo operation The gesture operation may be a sliding gesture or other predefined gestures, which are not particularly limited in this embodiment of the present application. The target file may include one or more, and the user can select the target file by clicking and/or long-pressing.

FIG. 19 is a schematic diagram of an application scenario of file sharing provided by an embodiment of the 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, wherein the mobile phone A2100 represents the first terminal device, which Wi-Fi direct connection is established with mobile phone B2200, large-screen device 2300 and pad2400 (second terminal device) respectively. As shown in Figure 19, the user can select a file on the mobile phone, point the mobile phone to the pad2400, and then share the file to the pad2400 through the sharing operation.

It can be understood that the user can also point the mobile phone A2100 to the large-screen device 2300 and share files to the large-screen device 2300; and the mobile phone A2100, mobile phone B2200, large-screen device 2300 and pad2400 can all discover each other. The other party establishes a Wi-Fi direct connection, and the user can also share files with other connected terminal devices through the pad2400 or the mobile phone B2200. Figure 19 is just an example of sharing files with the pad2400 through the mobile phone A2100. The interaction process between terminal devices is described below by taking the scenario shown in FIG. 19 as an example.

During specific implementation, after detecting the user's sharing operation, the first terminal device may broadcast a notification message (referred to as a first notification message) to notify each second terminal device.

The first notification message may carry a file identifier of the target file, such as a file name (the file name is also used as an example in the following description) to inform each second terminal device that the first terminal device will share the target file.

The first notification message may also carry the pointing direction of the first terminal device to identify the first notification message. For example, if the user has successively performed multiple sharing operations on the same target file, each sharing operation is aimed at a different first notification message. Two terminal devices, the first terminal device broadcasts a plurality of first notification messages correspondingly, and the first notification messages can be distinguished by the pointing direction of the first terminal device carried in the first notification message.

Specifically, the first notification message may be a broadcast message. In order to save resources, the first notification message may also be a multicast message. 20 is a schematic diagram of address information of each message in file sharing provided by the embodiment of the present application. As shown in FIG. 20 , the destination MAC address in the first notification message may be a multicast MAC address, and the source MAC address is the MAC address of mobile phone A.

S220. The second terminal device 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 the pointing azimuth of the corresponding second terminal device, so that the first terminal device can determine the pointing relationship with the second terminal device. Among them, the pointing azimuth can be measured by the azimuth sensor.

The response message may also carry a file name, so that the first terminal device can determine which first notification message the second terminal device replies to. For example, if the user has successively performed multiple sharing operations on the first terminal device to share different target files, the first terminal device correspondingly broadcasts multiple first notification messages, and each second terminal device receives each first notification message after receiving the respective first notification messages. , each first notification message may be responded to, and the file name may be carried in the response message to inform the first terminal device which first notification message it responded to.

In addition, the response message may also carry the pointing direction of the first terminal device to further identify the response message. For example, as mentioned above, the user has successively performed multiple sharing operations on the same target file, and each sharing operation is aimed at a different target file. The second terminal device, the first terminal device broadcasts a plurality of first notification messages correspondingly; after each second terminal device receives each first notification message, it can respond to each first notification message, and carry the message in the response message. The above file name and the pointing direction of the first terminal device are used to inform the first terminal device which first notification message it responds to.

In order to improve the accuracy of data sharing, the target device may be located within a preset range (referred to as the first preset range) around the first terminal device, and the response message may also carry the device location of the corresponding second terminal device, so that The first terminal device determines the target device based on the position, wherein the preset range may be a spherical area centered on the first terminal device, that is, the distance between the target device and the first terminal device does not exceed a preset distance; the The preset range may also be a columnar area centered on the first terminal device, that is, 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 may be set as required, which is not particularly limited in this embodiment; the device location may be obtained through a global positioning system (global positioning system, GPS) module and/or a map application.

MAC address, the source MAC address is the MAC address of the pad.

S230: After receiving the response message returned by each second terminal device, the first terminal device determines from the second terminal device according to the pointing bearing of the first terminal device corresponding to the sharing operation and the pointing bearing of the second terminal device in the response message target device.

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

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 determination of the pointing relationship between the first terminal device and each second terminal device, it can also According to the device position of the first terminal device and the device position of the second terminal device, the positional relationship between the first terminal device and each second terminal device is determined; the device position of the second terminal device is located at the device with the first terminal device When the position is within a preset range of the center, and the pointing orientation is opposite to the pointing orientation of the first terminal device, the second terminal device is determined as the target device. Wherein, in order to improve the accuracy of the determined positional relationship, the positional relationship between the first terminal device and the second terminal device may be corrected in combination with ranging technologies such as round trip time (round trip time, RTT) ranging.

When determining whether the pointing azimuth of the second terminal device is opposite to the pointing azimuth of the first terminal device, in order to improve the accuracy of the determination result, the device positions of the first terminal device and the second terminal device may be used for determination. 21 is a schematic diagram of determining the location range of a target device provided by an embodiment of the present application. As shown in FIG. 21 , point O is the device location of the first terminal device. If the second terminal device is located on the pointing line of the first terminal device, and If the pointing azimuth is consistent with the reverse azimuth of the pointing azimuth of the first terminal equipment, it can be considered that the pointing azimuth of the second terminal equipment is opposite to the pointing azimuth of the first terminal equipment, wherein the pointing line of the first terminal equipment is the same as that of the first terminal equipment. The position of the device is the starting point and extends along the pointing azimuth of the first terminal device.

For the convenience of the user, when determining whether the pointing orientation of the second terminal device is opposite to the pointing orientation of the first terminal device, a certain pointing error may be allowed. As shown in FIG. 21 , if the second terminal device is located within a preset range (referred to as the second preset range) with the pointing line of the first terminal device as the center line, and the pointing azimuth is opposite to the pointing direction of the first terminal device If the azimuth included angle between the azimuths is within the preset angle range, it can be considered that the pointing azimuth of the second terminal device is opposite to the pointing azimuth of the first terminal device. Wherein, the second preset range may be a cylindrical area or a square cylindrical 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 sizes of the second preset range and the preset angle range can be set as required, which are not particularly limited in this embodiment. It should be noted that, FIG. 21 takes the horizontal direction as an example to illustrate the position range of the target device, and the position range in the vertical direction is not shown.

Continuing to take FIG. 19 as an example, for the convenience of description, it is assumed that the device positions of each terminal device are on the same horizontal plane, the preset angle range is 15°, and the true north position is 0°. As shown in Figure 19, the pointing orientation of the mobile phone A2100 is 30° north by east (ie 30°), the pointing orientation of the mobile phone B2200 is 35° south west (ie 215°), and the pointing orientation of the large-screen device 2300 is due south position (ie 180°), the pointing orientation of pad2400 is 40° south-west (ie 220°), the large-screen device 2300 and pad2400 are located in the first preset range around the mobile phone A2100, and the mobile phone B2200 is located in the first preset range around the mobile phone A2100 Outside the preset range, the mobile phone B2200 and pad2400 are located within the second preset range with the pointing line of the mobile phone A2100 as the 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 the center line.

Based on the above information, it can be seen that the pad2400 is located in the first preset range around the mobile phone A2100; the reverse direction of the pointing azimuth of the mobile phone A2100 is 30° west by south (ie 210°), and the pointing azimuth (220°) of the pad2400 is the same as the mobile phone A2100. The azimuth angle (10°) between the reverse azimuth (210°) of the pointing azimuth is less than the preset angle range (15°), and the pad2400 is located in the second preset range with the pointing line of the mobile phone A2100 as the center line , therefore, the mobile phone A2100 can determine the pad2400 as the target device and share the picture A with it.

The azimuth angle (5°) between the pointing azimuth (215°) of the mobile phone B2200 and the reverse azimuth (210°) of the mobile phone A2100 is smaller than the preset angle range (15°), and the mobile phone B2200 is located at the same position as the mobile phone A2100. The pointing line is within the second preset range of the center line, but the cell phone B2200 is outside the first preset range around the cell phone A2100, so the cell phone B2200 is not determined as the target device of the cell phone A2100.

The large-screen device 2300 is located within the first preset range around the mobile phone A2100, but the large-screen device 2300 is located outside the second preset range with the pointing line of the mobile phone A2100 as the center line, and the pointing azimuth of the large-screen device 2300 (180°) ) and the reverse azimuth (210°) of the pointing azimuth of the mobile phone A2100 (30°) is greater than the preset angle range (15°), therefore, the large-screen device 2300 is not determined as the target device of the mobile phone A2100 .

It can be understood that the above target device determination process can also be performed in the second terminal device, that is, when the first terminal device sends the first notification message to the second terminal device, the device location and Pointing direction, after receiving the second terminal device, it can judge whether the local end is the target device, and then return the judgment result to the first terminal device.

If the first terminal device does not determine the target device, it may prompt the user that there is no target device, where the prompting manner may be a text prompt or a voice prompt.

If the first terminal device determines the target device, it can share the target file with the target device. 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.

S250. If the target device receives the second notification message, it checks whether the target file is stored.

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

If the target device determines that the target file is stored locally, it may load and display the target file for the user to view; or may also display prompt information to prompt the user that the target file to be shared by the first terminal device is locally stored.

S260. If the target device determines that no target file is stored, it sends 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, it 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 the file name of the target file, so that the first terminal device can identify the target file to be sent.

Optionally, the target device can ask the user whether to receive the target file in a pop-up dialog box as shown in (d) in Figure 17. In order to facilitate the user's operation, the target device can also not pop up the above-mentioned dialog box. If the user does not want to receive the target file, The second terminal device may not be aligned with the first terminal device, so that the solution can also be directly applied to other terminal devices that are inconvenient for users to operate, such as large-screen devices. Unified file sharing scheme.

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