Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the embodiments of the present application, "one or more" means one, two, or more than two; "and/or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, a and/or B, may represent: a alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

The embodiments of the present application relate to a plurality of numbers greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first", "second", and the like are used for distinguishing the description, and are not to be construed as indicating or implying relative importance or order.

In order to clarify the technical solution of the present application more clearly, the following explains the related concepts related to the present application.

A channel, which is a channel through which a signal is transmitted in a communication system, is formed by a transmission medium through which the signal is transmitted from a transmitting end to a receiving end. According to the IEEE 802.11 protocol, the 2.4GHz Wi-Fi band is divided into 13 overlapping channels, each channel is 22MHz wide (each channel bandwidth in the IEEE 802.11g standard and the IEEE 802.11n standard is 20MHz, and each channel bandwidth in the IEEE 802.10B standard is 22 MHz); the 5GHz Wi-Fi band is divided into 201 channels.

Wi-Fi P2P is the Wi-Fi peer-to-peer (P2P) standard promulgated by the Wireless Fidelity (Wi-Fi) alliance (alliance). Wi-Fi P2P connections are created on demand when a user initiates a P2P service, typically taking 3.5-20 s. The modes of Wi-Fi P2P connection may include:

mode one, standard mode (standard)

Wi-Fi P2P connection initialization in standard mode includes 4 key processes of discovery (discovery), Group Owner (GO) negotiation, provisioning (provisioning), and IP address initialization. After the discovery process is completed, the discovered device can be displayed on the discovered device and waits for the user to select. Specifically, the discovery process includes 2 processes of scanning (scan) and finding (find). The find process comprises a search (search) and a listen (listen) process, and the search and listen cycle back and forth until, or discovered by, the peer device. Generally, scan is a full channel scan. A scan's full channel scan typically takes 900 milliseconds (ms) to 2 seconds(s), and the search and listen process typically takes 200ms to 10 s. The shortest time consumption and the longest time consumption of the search process are greatly different, mainly because the Wi-Fi P2P adopts a time division mechanism and the search time consumption is unstable.

The biggest limitation of the standard mode is that scan and find use channel switching to send probe requests (probe requests) on different channels. In order for the receiver to send a request response, the receiver and the sender need to be in the same channel. And the two parties do not know the channel used by the other party before negotiation, so that at least one of the two parties changes the channel to repeatedly send the probe request, and the process is circulated until the opposite party equipment is found or the opposite party equipment is found. Therefore, the whole process takes a long time and is unstable in overall time.

For example, if the channel through which the sender currently sends the negotiation request to the receiver is the a channel, the channel through which the receiver currently receives the negotiation request is the b channel. Because the current channels used by the receiver and the sender are not the same channel, the receiver cannot receive the negotiation request sent by the sender device through the channel a and cannot respond to the negotiation request through the channel b. The sender changes the channel, the receiver may also change the channel, and both parties negotiate again. At least one of the sender and the receiver may change the channel for multiple times, and the process is repeated until the channels of the two parties are the same finally, and the receiver receives the negotiation request sent by the sender. This results in a long overall process time and overall time consuming instability.

As can be seen from the above, discovery in the standard mode takes a long time and is not stable for a long time. In addition, the user can typically only make device selections after the discovered device discovers the discovered device via discovery. Therefore, the initialization of the P2P service is time-consuming and unstable in duration, and the user experience is not good.

Mode two, persistent mode (persistent)

Group (group) configuration information may be persisted after the first connection in the persistent mode, and GO negotiation procedures may be omitted for subsequent connections. Also, the Provisioning process is simplified. However, persistent mode increases invocation; the discovery process of the continuous mode is the same as that of the standard mode, and is not simplified; therefore, the initialization of the P2P service is time-consuming and unstable, and the user experience is not good.

That is, both of the above modes of Wi-Fi P2P connection result or may result in a Wi-Fi P2P connection that is time consuming and has a poor user experience.

Next, a Wi-Fi P2P connection method between one electronic device and another electronic device will be described. In order to easily distinguish the electronic device from another electronic device and avoid confusion in names, in the following description, the electronic device is replaced with a mobile device and the electronic device is replaced with another electronic device. It should be noted that this is merely for convenience of distinguishing names and avoiding confusion, and is not intended to limit the specific type of device.

Optionally, when more than two electronic devices of the same type (e.g., two smart tvs) are stored in table 1, the device display interface or other interface (e.g., a desktop) that can establish the Wi-Fi P2P connection may display, in addition to an icon of the smart tv, an identifier (e.g., a name, etc.) for distinguishing the two smart tvs.

The ID of the electronic device may not be an SSID, or may not be a BSSID. For example, the ID of the electronic device is an identifier associated with the SSID or BSSID of the electronic device, and the SSID or BSSID of the electronic device can be queried through the ID of the electronic device. The ID of the electronic device may also be an identification associated with the SSID and BSSID of the electronic device.

Optionally, after receiving another input (e.g., a voice input, a touch input, etc.), the mobile device ends the flow of the initial setup step.

Alternatively, if the mobile device does not receive the broadcast message within a preset time period (e.g., 1 minute), the process of the initial setting step of the mobile device is ended.

For example, the mobile device may also configure its own channel as a channel corresponding to the ID of the electronic device, then configure itself as a GC device, and then establish a Wi-Fi P2P connection with the electronic device (GO device) according to the authentication information and the address information in the Wi-Fi P2P connection information.

S706a, the mobile device scans on each channel in turn.

If the mobile device does not inquire the ID of the electronic device in a preset memory, the mobile device scans each channel of the working frequency band of the mobile device in sequence.

Illustratively, the mobile device scans in turn on each channel on each operating frequency band supported by the mobile device.

Optionally, if the mobile device supports M operating frequency bands, the mobile device sequentially scans all channels on the 1 st operating frequency band — the mth operating frequency band. For example, the mobile device supports 2 operating bands, the number of channels on the 1 st operating band is N1, and the number of channels on the second operating band is N2, then the mobile device may perform each channel scan on N1 channels of the 1 st operating band first, and then perform each channel scan on N2 channels of the 2 nd operating band.

Specifically, if the mobile device supports the 2.4GHz band and the 5GHz band, the mobile device may perform full channel scanning on the 2.4GHz band first, and then perform full channel scanning on the 5GHz band; the mobile device may also perform full channel scanning on the 5GHz band first, and then perform full channel scanning on the 2.4GHz band. That is, the mobile device may perform a scan of each channel for each frequency band in turn over all frequency bands supported by the mobile device.

Optionally, if the mobile device supports the 2.4GHz band and the 5GHz band, the mobile device may perform full channel scanning on the currently operating band first, and then perform full channel scanning on another band.

S707a, whether the mobile device receives a message sent by the electronic device.

In the scanning process, if the mobile device receives a message sent by the electronic device, S708a is executed; if the mobile device does not receive a message sent by the electronic device, S710a is performed. In the scanning process, if the mobile device receives a message sent by the electronic device, it indicates that the current channel of the mobile device is the channel used by the electronic device.

S708a, whether the message contains the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device.

If the mobile device determines that the message includes the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device, S709a is performed.

S709a, acquiring the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device, and storing the acquired information in a preset memory.

The mobile device acquires the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device from the message, and stores the acquired information in a preset memory. The predetermined memory may be a memory local to the mobile device, or may be a memory (e.g., a third-party storage device) associated with the mobile device, other than the mobile device.

After S709a, S705a is performed.

Optionally, in S708a, if the mobile device determines that the message includes the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device, S705a is performed first; thereafter, S709a is executed again. That is, in S708a, if the mobile device determines that the message includes the ID of the electronic device and the Wi-Fi P2P connection information of the electronic device, the mobile device configures itself first and establishes Wi-Fi P2P connection with the electronic device; and then, storing the ID of the electronic equipment and the Wi-Fi P2P connection information in a preset memory.

S710a, whether all channels are scanned is complete.

If the mobile device does not receive the message sent by the electronic device in S707a, the mobile device determines whether all channels are completely scanned.

The mobile device determines whether all channels on all operating frequency bands supported by the mobile device have been scanned. Alternatively, if the mobile device supports two operating bands, after all channels on one operating band are scanned, all channels may be scanned on the other operating band. The two operating bands are only illustrative examples. If the mobile device supports M operating frequency bands (M is a positive integer greater than or equal to 2), all channels on one operating frequency band can be scanned, and after all channels on the M operating frequency bands are not scanned, full channel scanning can be performed on another operating frequency band of the M operating frequency bands, so that all channels under all operating frequency bands are scanned.

If all channels are not scanned, S706a is executed.

Optionally, in S710a, if all channels are scanned, the mobile device determines that the Wi-Fi P2P connection fails this time.

Alternatively, when the mobile device executes according to the flow illustrated in fig. 7A, the electronic device may execute according to the flow illustrated in fig. 5. For example, when the mobile device performs S706a, the electronic device may perform S503. If the electronic device is not powered on (e.g., power off), or no longer broadcasts messages, the mobile device does not receive a message from the electronic device on which channel if the full channel scan started at S706 a; so that the mobile device determines that this Wi-Fi P2P connection failed.

By the method, in the using steps of the mobile device and the electronic device, after the mobile device receives an input, the mobile device acquires the ID of the electronic device, and searches the Wi-Fi P2P connection information corresponding to the ID of the electronic device from the preset memory, so that the mobile device can acquire the channel, the authentication information, and the address information in the Wi-Fi P2P connection information, configure the channel thereof as the channel corresponding to the ID of the electronic device, and quickly complete Wi-Fi P2P connection with the electronic device according to the authentication information and the address information in the Wi-Fi P2P connection information, thereby effectively shortening the time length for establishing connection between the mobile device and the electronic device through the Wi-Fi P2P.

Fig. 7B is a flowchart illustrating an embodiment of a mobile device in the using step of the Wi-Fi P2P connection method provided in the present application. As shown in fig. 7B, the process may include:

s701b-S703 b: see the description of S701a-S703a, which are identical to S701a-S703a, respectively;

s706b-S710 b: respectively identical to S706a-S710a, please refer to the descriptions of S706a-S710 a;

s704b, acquiring Wi-Fi P2P connection information corresponding to the ID from a preset memory, configuring a channel of the terminal as a channel in Wi-Fi P2P connection information, configuring the terminal as a GC device, and acquiring authentication information and address information in the Wi-Fi P2P connection information;

illustratively, Wi-Fi P2P connection information corresponding to the ID of the electronic device is acquired from table 1 of a preset memory, and a channel, authentication information, address information, and the like are acquired therefrom.

Illustratively, the mobile device configures itself as a GC device, configures its channel as a channel corresponding to the ID of the electronic device, and prepares to establish a Wi-Fi P2P connection with the electronic device (GO device) according to the authentication information and the address information in the obtained Wi-Fi P2P connection information.

For example, the mobile device may also configure its own channel as a channel corresponding to the ID of the electronic device, then configure itself as a GC device, and prepare to establish a Wi-Fi P2P connection with the electronic device (GO device) according to the authentication information and the address information in the obtained Wi-Fi P2P connection information.

S705b, whether the Wi-Fi P2P connection can be established with the electronic equipment or not;

then, judging whether the Wi-Fi P2P connection can be established with the electronic equipment or not; if so, then S711b is performed; if not, execution proceeds to S706 b.

S705b is set, and after the judgment result of S705b is NO, S706b is executed; mainly considering that some electronic devices or some electronic device may change at least one of the channel, the authentication information and the address information after a period of time; in this way, the Wi-Fi P2P connection information of these electronic devices or one electronic device can be acquired and stored in a full channel scanning manner. And, the changed Wi-Fi P2P connection information would overwrite the previous Wi-Fi P2P connection information.

For example, the ID of the electronic device a is ID1, and the channel, the authentication information, and the address information in the previous Wi-Fi P2P connection information are: channel 1, authentication information 1, and address information 1; later, for some reason (e.g., security reasons), Wi-Fi P2P connection information for electronic device a was changed; the channel, authentication information and address information in the changed Wi-Fi P2P connection information are respectively: channel 2, authentication information 2, and address information 2. Thus, the changed Wi-Fi P2P connection information can be stored in the preset memory by the method. And, the changed Wi-Fi P2P connection information would overwrite the previous Wi-Fi P2P connection information. Thus, in the preset memory, the Wi-Fi P2P connection information corresponding to the ID of the electronic device A only has the changed Wi-Fi P2P connection information. In this way, an effective automatic change is provided.

Optionally, the Wi-Fi P2P connection information may be changed through an initial setting step; the same technical effect is achieved.

And S711b, establishing the Wi-Fi P2P connection with the electronic equipment.

The method of this embodiment not only achieves the technical effect of fig. 7A, but also further considers the case where there is a change in Wi-Fi P2P connection information stored in the preset memory. Aiming at the situation that after the mobile device acquires the Wi-Fi P2P connection information corresponding to the ID of the electronic device, the mobile device cannot establish Wi-Fi P2P connection with the electronic device, the changed Wi-Fi P2P connection information is acquired in a full-channel scanning mode, and is stored in a preset memory in a mode of covering the previous Wi-Fi P2P connection information. In this way, when the Wi-Fi P2P connection information of the electronic device is changed, the connection information can be judged by self, actively acquired and stored, so that the latest Wi-Fi P2P connection information can be acquired from a preset memory later.

Unless otherwise specified, the content not described in the embodiment corresponding to fig. 7B is the same as the related content in the embodiment corresponding to fig. 7A. And will not be described in detail herein. For example, the storage locations in table 1 in the embodiment corresponding to fig. 7B are not illustrated, and thus the relevant contents are the same as those in the embodiment corresponding to fig. 7A; therefore, in the embodiment corresponding to fig. 7B, table 1 is also stored in the preset memory.

Alternatively, the flow method shown in fig. 7B may not be employed. For example, in S709a in fig. 7A, when the ID of the electronic device and the corresponding Wi-Fi P2P connection information are stored, the storage time is also stored in the preset memory. In S703a and S704a, after querying a plurality of IDs, the latest (i.e., latest) correspondence of the storage time or the Wi-Fi P2P connection information in the storage record is selected. In this way, the changed Wi-Fi P2P connection information of another electronic device can be acquired. This scheme is also well known to those skilled in the art in the method shown in FIG. 7A.

For example, as shown in fig. 8, in the Wi-Fi P2P connection method according to the embodiment of the present application, based on the Wi-Fi P2P connection information, the process of the mobile device establishing a Wi-Fi P2P connection with the electronic device may include:

and S810, the mobile device sends a Wi-Fi P2P access request to the electronic device.

In one example, the Wi-Fi P2P access request contains a key for Wi-Fi P2P access.

And S820, the electronic equipment verifies whether the verification is correct.

If the verification is correct, S830 is performed.

In one embodiment, if the verification is incorrect, the number of times of verification is recorded as 1, and the verification is performed again after waiting for a preset time; if the verification is incorrect again, the verification times are increased by 1. And circulating the steps, and stopping verification if the verification times are still incorrect after reaching the preset verification times.

In another embodiment, if the verification is incorrect, the verification is performed again after waiting for a predetermined time period; if the authentication is incorrect again, a message is sent to the mobile device to inform the mobile device that the Wi-Fi P2P access key is wrong; or the electronic equipment informs the Wi-Fi P2P that the accessed key is wrong through a voice output or message display mode.

S830, the electronic device sends a confirmation message to the mobile device to confirm that the Wi-Fi P2P establishes connection.

The mobile device receives the confirmation message sent by the electronic device. And the Wi-Fi P2P connection channel is established.

It should be noted that the above-mentioned S810-S830 are only schematic illustrations. During the Wi-Fi P2P channel establishment procedure between the mobile device and the electronic device, there may be a number of loop procedures similar to those described above at S810-S830. Only, the messages sent by the mobile device to the electronic device, and the messages sent by the electronic device to the mobile device, are replaced or changed. There is no further expansion.
