Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices, and the first device and the second device described below are both the electronic devices. The following describes embodiments of the present application in detail.

Firstly, a NAN mechanism is briefly introduced, a Neighbor Awareness Network (NAN) mechanism is a standard formulated by a wireless fidelity Wi-Fi alliance, the standard is used for synchronizing all devices (namely NAN devices) participating in the NAN mechanism under the condition that no central node exists, maintaining work and Service Discovery work of the NAN mechanism are performed in a Discovery Window (DW) agreed by the NAN mechanism, Service Discovery is realized by sending a Service Discovery Frame (SDF) message, and the Service Discovery Frame message comprises an inquiry message or a broadcast message. The device may establish a corresponding connection based on the information obtained in the service discovery and then perform data transmission.

Specifically, in the standard specified by the Wi-Fi alliance, channel 6 may be used as the discovery channel in the NAN mechanism, and on channel 6, the duration of the discovery time window DW is fixed for each cluster, and the time interval between any two DWs adjacent to the cluster is also fixed.

In the NAN mechanism, a Discovery Window (DW) is set, and NAN devices perform service discovery in the DW. In the NAN mechanism, a DW is generally set in each 512 TUs (time unit), wherein the duration of one TU is about 1024 μ s, and the duration of the DW is generally 16 TUs, that is, in the NAN mechanism, a DW is generally set every 496 TUs. In the NAN mechanism, one or more NAN devices form a Cluster (also called a neighbor awareness network), when a Cluster enters a DW, a NAN device in the Cluster in a master node (master), an anchor master node (AM), a master node (non-master synchronization, non-master sync) state and the like sends a synchronization beacon frame (sync beacon) message, where the message carries information of the AM in the Cluster, and the NAN device receiving the message synchronizes with the AM in the Cluster.

For example, as shown in fig. 1, which is a schematic diagram of a DW of a cluster, according to a standard established by the Wi-Fi alliance, in the DW, NAN devices in the cluster may send a service discovery frame SDF message in the DW to perform service discovery, and in a time other than the DW, NAN devices in the cluster may send a discovery beacon (discovery beacon) message to announce the existence of the cluster. Each NAN device in the cluster may perform service discovery in the DW to discover other NAN devices with which data transmission can be performed. After service discovery, at least two NAN devices which need to perform data transmission with each other may agree on a time frequency resource and a network connection mode in the DW, and after the DW is finished, assemble a corresponding NAN network without a center node on the agreed time frequency resource according to the agreed network connection mode.

The flow of completing service discovery by the NAN device is as follows:

1. after a device activates the NAN function (i.e., becomes a NAN device), it may set itself as an AM, create a Cluster, set a Cluster Identity (Identity, ID) value of the Cluster based on its MAC (Media Access Control) address, and set the TSF as an integer multiple of 512 TU.

2. Once the NAN device receives a Beacon frame (i.e., a sync Beacon, hereinafter, referred to as Beacon frame) sent by a NAN device from one or more other clusters, it may determine whether the NAN device wants to join the Cluster of the other peer.

In the Beacon frame, information of the corresponding Cluster is generally carried, and specifically, information of an AM in the corresponding Cluster may be specifically carried, and may include one or more of an Anchor Master node rank (AMR), a Master node rank (MR), a Master node priority (Master priority, MP), an Anchor Master node priority (AMP), a Random Factor (RF), an Anchor Master node signal Transmission Time (AMBTT), a Time Synchronization Function (TSF), a Cluster ID, and a Cluster rank (CG).

One NAN device may send information of the AM of the Cluster to which the NAN device belongs to other NAN devices by sending the Beacon frame, and similarly, one NAN device may also receive the Beacon frame sent by the Cluster or the NAN devices in other clusters.

After receiving a Beacon frame, the NAN device may determine whether the Beacon frame is from a NAN device in the Cluster to which the NAN device belongs or from NAN devices in other clusters, if the Beacon frame is from NAN devices in other clusters, the NAN device may determine whether a value of Cluster level CG in the received Beacon frame is greater than a value of Cluster level CG of the NAN device, if the value is greater than the value, the NAN device adds the Cluster corresponding to the received Beacon frame, otherwise, the NAN device does not perform processing. This completes the aggregation of NAN devices, i.e., NAN devices will join Cluster with a higher value of Cluster level CG.

3. If the determination is made that the other party's Cluster is to be added, the synchronization is achieved with the AM in the added Cluster after the other party's Cluster is added, specifically, each item of parameter information in the AM of the self is synchronized with the AM in the added Cluster, for example, the TSF of the AM in the Cluster is updated to the TSF of the AM in the added Cluster.

4. After synchronization, when a DW of a joined Cluster arrives, the NAN device sends an SDF (Service Discovery frame) message in the DW to perform Service Discovery, where the SDF message may carry, for example, Service Discovery (Service Subscription) information for querying a required Service or may carry, for example, Service publication (Service Publish) information for publishing a Service that the NAN device can provide, and after receiving the SDF message sent by the NAN device, other NAN devices may reply the SDF message to the NAN device in the DW if it is determined that the SDF message is satisfied, that is, Service matching can be performed.

Similarly, in the DW, the NAN device may also receive an SDF message sent by another NAN device for service discovery, and if the NAN device determines that the received SDF message is satisfied, the NAN device may also reply the SDF message to the corresponding NAN device in the DW.

Various types of information contained in the AM are explained below.

The anchor master node level AMR, which is generally a maximum value of 8 bytes (byte), is the MR value of AM.

The master node level MR, which generally takes a maximum value of 8 bytes, is calculated according to the MP value, the RF value, and the MAC address of the NAN device, and indicates the will of the NAN device to act as a master. The larger the value of MR, the higher will the NAN device want to be master. MR can also be considered as an alternative expression of MP.

The master node priority MP, which generally takes a maximum value of 1 byte, indicates the willingness of the NAN device to act as a master. The larger the value of MP, the higher will the NAN device want to be master.

The anchor master node priority AMP, which generally takes a maximum value of 1 byte, is the value of the MP of the AM.

The random factor RF, which generally takes a maximum value of 1 byte, is a random number selected by the NAN device.

The anchor master node signal transmission time AMBTT generally takes a maximum value of 4 bytes, and shows the sending time of the Beacon frame of the AM. Generally, a NAN device sending a Beacon frame carries an AMBTT, and is used for synchronizing the time of other NAN devices with an AM corresponding to the AMBTT.

The time synchronization function TSF, which generally takes a maximum value of 8 bytes, indicates a synchronization function of the NAN device, so that a timer (timer) of the NAN device receiving the TSF is synchronized with a time of the AM corresponding to the NAN device sending the TSF. The TSF may also represent time information.

The Cluster identity identifier Cluster ID generally takes a maximum value of 6 bytes, and is carried in an Address (Address) 3 field in the Beacon frame.

The Cluster level CG generally takes a maximum value of 8 bytes, represents the level of Cluster, is used for comparing different Clusters during combination, and the Cluster with a small CG value is combined into the Cluster with a large CG value.

The service discovery frame SDF message is introduced below.

The SDF message is an Action Frame (Action Frame) specially defined for service discovery, and can be roughly divided into three types according to different functions: the SDF issues a Publish message, subscribes to a Subscribe message, and replies to a Follow-Up message, and generally, an indication bit is included in the SDF message to indicate which SDF message the SDF message is.

SDF Publish message: the NAN equipment is used for publishing services which can be provided by the NAN equipment or replying to the received SDF Subscribe messages sent by other NAN equipment;

SDF Subscribe message: for finding the service to be used;

SDF Follow-Up message: for replying to received SDF Publish messages or for negotiating more information.

Referring to fig. 2, fig. 2 is a flowchart illustrating a data sharing method according to an embodiment of the present application, applied to a first device, where the first device is a neighbor aware network NAN device in a NAN network, and as shown in the drawing, the data sharing method includes:

s201, when a first device detects a sharing request aiming at target data, downloading the target data to a local annular cache region, wherein the target data comprises audio data and/or video data;

the sharing request for the target data is actively triggered by the user of the first device, for example, by selecting a video sharing function trigger of the first device, the triggering condition is not uniquely defined, and when the user sees a favorite audio or video, the user wants to share the favorite audio or video with a friend or a relative person, the sharing request for the target data is actively triggered.

S202, the first device broadcasts a first service discovery frame SDF message to a plurality of devices in a first cluster except the first device, where the first SDF message includes shared service request information and at least one second device identifier, and the at least one second device is a device that shares the target data with the first device;

the first SDF message at least includes a device identifier of at least one second device (i.e., a device identifier of a friend who wants to share), an identifier of target data, and the like, and the first SDF message may specifically be an SDF Publish message.

The first device can download target data from the internet through the data network and can share the target data to the at least one second device through the NAN network.

Wherein, the plurality of devices may include the at least one second device, or may not include the at least one second device, and when the at least one second device is not included, the at least one second device may receive the first SDF message through the relay device in the first cluster.

S203, the first device receives a second SDF message from the at least one second device, where the second SDF message includes feedback information for the shared service request information;

the second SDF message may specifically be an SDF Follow-Up message, where the feedback message is used to indicate that the at least one second device receives the first SDF Publish message, and whether the at least one second device receives the target data.

S204, the first device negotiates a transmission channel of the target data with the at least one second device.

In a specific implementation, for a transmission channel between a first device and at least one second device, the negotiation process may be that the first device performs channel transmission negotiation with the at least one second device through an SDF Follow-Up message; moreover, any two devices in the at least one second device may also negotiate a transmission channel for data transmission, and for a transmission channel between any two second devices except the first device, the first device may first group the at least one second device, select one master device for each group, and notify the master device to negotiate a transmission channel with other devices in the group.

S205, the first device transmits the target data to the at least one second device through the negotiated transmission channel.

The first device may send the target data of the local end to at least one second device through each transmission channel, where the target data may also be transmitted through a transmission channel between the second device and the relay device and a transmission channel between the relay device and the first device, which is not limited herein.

In a specific implementation, the first device may also send the target data to the master device in each group through the transmission channel, and then the master device sends the target data to other second devices in the group, so as to reduce the data transmission pressure of the first device.

After the first device transmits the target data to the at least one second device through the negotiated transmission channel, the first device may stop sharing the target data at any time and release the transmission channel.

In one possible example, the plurality of devices in the first cluster other than the first device include a relay device, and the relay device is configured to broadcast the first SDF message in a cluster other than the first cluster in which the relay device is located when receiving the first SDF message of the first device.

The relay device is a NAN device having a relay function, and is a NAN device existing in at least two clusters, that is, when there is a device not in a first cluster in at least one second device, the first SDF message may be obtained through forwarding by the relay device, and further, another relay device may be included in a cluster other than the first cluster, and the first SDF message may also be broadcast in more clusters, so that the first SDF message may be obtained in any cluster in which the at least one second device is.

For example, after all the at least one second device receives the first SDF message, the relay device may stop forwarding the first SDF message by more relay devices, or each time the forwarded first SDF message includes an identifier of a relay level, for example, when the forwarded relay device is a device in a first cluster, the identifier of the relay level is 1, when the relay device in the next layer forwards the first SDF message, the identifier of the relay level is 2, when the level is greater than a preset level, the relay device stops forwarding the first SDF message by more relay devices, thereby avoiding that transmission delay between each message and target data is caused by excessive levels.

As can be seen, in this example, the first device may forward the first SDF message to the multiple clusters through the relay device in the first cluster, so as to avoid that when the first cluster does not include all of the at least one second device, the at least one second device cannot receive the first SDF message, which is beneficial to ensuring the implementation of data sharing and improving the stability of data sharing.

In this possible example, the receiving the second SDF message from the at least one second device includes:

receiving the second SDF message from each first target device in the first group of target devices, the each first target device being in the first cluster;

receiving, by the relay device, the second SDF message from each second target device in the second group of target devices, the each second target device not being in the first cluster.

As can be seen, in this example, the first device may receive the second SDF message sent by the at least one second device in two ways, and the two ways may be transmitted simultaneously, which is beneficial to improving stability and reachability of message reception.

In one possible example, the transmitting the target data to the at least one second device through the negotiated transmission channel includes:

determining a playing time node of the target data in the first device;

and transmitting the target data containing the playing time node identifier to the at least one second device through the negotiated transmission channel, wherein the playing time node identifier is used for instructing the at least one second device to play the target data according to the playing time node identified by the playing time node identifier.

The playing time node is the playing time of the target data when the user of the first device triggers the sharing request, and is, for example, 2min, 5min, and the like.

Wherein the playing time node can also be adjusted manually if the user wants to view the target data from the beginning.

It can be seen that, in this example, when the first device transmits the target data to the at least one second device, the playing time node is transmitted at the same time, and the at least one second device can play the target data according to the playing time node, so as to realize synchronous watching with the first user, that is, the traffic of the second device is saved, and the interest of data sharing is improved.

In one possible example, after the target data is transmitted to the at least one second device through the negotiated transmission channel, the method further includes:

detecting comment information input by a user of the first device for the target data;

and transmitting the comment information to the at least one second device through the negotiated transmission channel, wherein the comment information is used for the second device to display the comment information.

The comment message may be a voice message or a text message, and is not limited herein, if the text message may be displayed on the second device in the form of a bullet screen, if the text message is a voice message, the text message may also be directly played after being received by the second device.

It can be seen that, in this example, after the first device shares the target data with the second device, the user's observation and comment is transmitted to the second device while the target data is being watched synchronously, and the two users can exchange the same audio and video on one platform in real time for the same playing node, so that convenience of message interaction is improved, and data traffic is saved.

receiving a third SDF message from the at least one second device, the third SDF message instructing the at least one second device to suspend receiving the target data;

and stopping sending the target data to the at least one second device, and releasing the transmission channel if a fourth SDF message for indicating to resume receiving the target data is not received in a preset time period.

The third SDF message and the fourth SDF message may specifically be SDF Follow-Up messages.

The preset time period may be, for example, a remaining playing time period of the target data, or may be preset 5min, 10min, and the like, which is not limited herein.

As can be seen, in this example, the first device may control transmission of the target data through the third SDF message or the fourth SDF message sent by the at least one second device, which is beneficial to improving flexibility of data sharing, and in addition, within a preset time period, the transmission channel is released, occupation of data transmission resources is stopped, which is beneficial to avoiding waste of NAN network resources.

In one possible example, before broadcasting the first service discovery frame SDF message to a plurality of devices in the first cluster other than the first device, the method further comprises:

enabling a NAN function;

detecting the distance between the first equipment and each equipment in a preset area through the NAN function according to a preset ranging strategy;

screening the plurality of devices with the distances smaller than a preset distance threshold;

forming the first cluster with the plurality of devices and completing synchronization of each device in the first cluster.

First, the first device sends an FTM Request (FTM Request) to each device (e.g., hereinafter, referred to as a reference NAN device) in a preset area where the first device is to be subjected to ranging, where the FTM Request is used to Request a periodic time window, and after receiving the FTM Request, the reference NAN device may reply a message indicating acceptance or resetting of the time window according to its resource condition, capability, and the like. Wherein, the FTM Request is an Action Frame.

2. The reference NAN device and the first device both begin time capture if the preset time window is accepted by the reference NAN device. The time when the reference NAN device captures the reply message for the FTM Request from the reference NAN device to the first device is t1, and the time when the first device captures the reply message for the FTM Request received by the reference NAN device is t 2.

3. The first device replies an ACK (Acknowledgement) to the reply message to the reference NAN device, and captures a time when the ACK is sent as t3, and captures a time when the ACK is received as t 4.

4. If the first device is to complete ranging, the reference NAN device sends a ranging message to the first device, where the ranging message carries t1 and t 4.

Thus, the first device obtains four times, i.e. Time t1, Time t2, Time t3, and Time t4, so that the Round-Trip Time RTT (Round-Trip Time) of the message can be calculated as:

RTT＝[(t4–t1)–(t3–t2)] (1)

the distance d between the first device and the reference NAN device may then be calculated as:

d＝1/2*RTT*c (2)

where c is the speed of light, and may also be equal to the transmission speed of Wi-Fi signals.

Therefore, in this example, the first device triggers the NAN function based on the request, the NAN function is kept closed in a normal state, the electric quantity is saved, the first device can quickly screen out the potential devices conforming to the NAN network based on the distance detection, and the efficiency of NAN network creation is improved.

S306, the first device determines a playing time node of the target data in the first device.

S307, the first device transmits the target data including the play time node identifier to the at least one second device through the negotiated transmission channel, where the play time node identifier is used to instruct the at least one second device to play the target data according to the play time node identified by the play time node identifier.

In addition, the first device may forward the first SDF message to the multiple clusters through the relay device in the first cluster, so that when the first cluster does not include all of the at least one second device, the at least one second device may not receive the first SDF message, which is beneficial to ensuring the implementation of data sharing and improving the stability of data sharing.

In addition, when the first device transmits the target data to the at least one second device, the playing time node is transmitted at the same time, and the at least one second device can play the target data according to the playing time node, so that the target data can be synchronously watched with the first user, that is, the flow of the second device is saved, and the interest of data sharing is improved.
