Background

With the continuous development of communication technology, the applications of bluetooth transmission and Wi-Fi (Wireless Fidelity) transmission in the data transmission field of intelligent devices are relatively wide, wherein:

4. The term "BLE" in the embodiment of the present invention refers to a key technology proposed by the bluetooth 4.0 specification, which is used for discovering devices and performing some simple communications, and has the advantages of low operating power consumption and low standby power consumption, but the transmission rate of BLE is relatively low, and is not suitable for transmitting a large amount of data streams.

5. The term "packet" in the embodiments of the present invention refers to a data unit, i.e., a data block, exchanged and transmitted in a network, and includes complete data information to be sent.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.

The following takes a mobile phone as an example to introduce the scheme of the invention:

suppose that the two mobile phones share files in a mode of combined transmission of bluetooth and Wi-Fi, wherein a file sender is a mobile terminal 1, and a file receiver is a mobile terminal 2. The mobile terminal 1 and the mobile terminal 2 are respectively provided with a function switch for joint transmission of Bluetooth and Wi-Fi P2P, and when the function switch is clicked, the Bluetooth and WLAN functions are simultaneously started, wherein the WLAN functions comprise Wi-Fi hotspot connection and Wi-Fi P2P connection.

After the WLAN function is turned on, the mobile terminal 1 determines, through the scanned BLE broadcast message, a mobile terminal that supports bluetooth and Wi-FiP2P joint transmission, such as: and if the scanned BLE broadcast message contains preset UUID information which indicates that the Bluetooth and Wi-Fi P2P joint transmission is supported, determining that the mobile terminal sending the BLE broadcast message has the Bluetooth and Wi-Fi P2P joint transmission function. The mobile terminal 1 analyzes the scanned BLE broadcast message containing the preset UUID information to obtain the equipment name of the mobile terminal sending the BLE broadcast message, and adds the equipment name to an equipment list which supports the combined transmission of Bluetooth and Wi-Fi P2P in the local.

For example, referring to fig. 1A, the mobile terminal 1 parses the scanned BLE broadcast packet containing the preset UUID information, and the parsed device name is "mobile terminal 2", then the mobile terminal 1 adds "mobile terminal 2" to a local "connectable device searched by me" list, where "unconnected" displayed behind "mobile terminal 2" in the device list indicates that the mobile terminal 1 and the mobile terminal 2 are in an unconnected state.

At this time, if the user selects "mobile terminal 2" through the device list of mobile terminal 1, mobile terminal 1 sends a request for establishing Wi-Fi P2P connection to mobile terminal 2, and if mobile terminal 1 receives a response for agreeing to establish Wi-Fi P2P connection sent by mobile terminal 2, the connection establishment between mobile terminal 1 and Wi-Fi P2P of mobile terminal 2 is completed. The mobile terminal 1 performs data transmission, i.e. file sharing, with the peer device through the Wi-FiP2P connection, where the mobile terminal 2 is the peer device of the mobile terminal 1 in the above example, and the whole process is described below in terms of the mobile terminal 2:

correspondingly, after a function switch jointly transmitted by Bluetooth and Wi-Fi P2P on the mobile terminal 2 is clicked and opened, the Bluetooth and WLAN functions on the mobile terminal 2 are simultaneously started, after the WLAN function is started, the mobile terminal 2 sends a BLE broadcast message containing preset UUID information, after the mobile terminal 2 receives a request for establishing Wi-Fi P2P connection sent by the mobile terminal 1, if a user clicks an agreement key, the mobile terminal 2 sends an agreement for establishing Wi-Fi P2P connection response to the mobile terminal 1, and the mobile terminal 2 receives a shared file sent by the mobile terminal 1 through the established Wi-Fi P2P connection.

It should be noted that, the above-mentioned taking the mobile terminal 1 as an initiator for establishing the Wi-Fi P2P connection and the mobile terminal 2 as an opposite device for passively waiting for the Wi-Fi P2P connection are only examples, and the operation of any one party is not limited to all functions integrated on the mobile terminal in the embodiment of the present invention. That is, in this process, the mobile terminal 2 may also serve as an initiator initiating the establishment of the Wi-Fi P2P connection, and the mobile terminal 1 serves as a receiver receiving the request for establishing the Wi-Fi P2P.

It can be understood that, while scanning the BLE broadcast message, the mobile terminal 1 also sends the BLE broadcast message containing the preset UUID information; the mobile terminal 2 sends a BLE broadcast message containing the preset UUID information and scans the BLE broadcast message, that is, both the mobile terminal 1 and the mobile terminal 2 are bidirectionally scanned. Therefore, the mobile terminal 1 may also perform the specific operation steps of the mobile terminal 2 described above; the mobile terminal 2 may also perform the specific operation steps of the mobile terminal 1 described above. As shown in fig. 1B, the mobile terminal 1 adds the mobile terminal 1 to a local connectable device list according to the scanned BLE broadcast packet, and the mobile terminal 1 also sends the BLE broadcast packet while scanning the BLE broadcast packet; while the mobile terminal 2 sends the BLE broadcast message, the mobile terminal 1 can also be added to a local "i search connectable device" list of the mobile terminal 2 according to the scanned BLE broadcast message containing the preset UUID information sent by the mobile terminal 1, so that a user can select Wi-Fi P2P connection on the list, and connect to an opposite terminal device for file sharing through Wi-Fi P2P.

Because the BLE broadcast message used in the embodiment of the invention is a scannable non-directional type BLE broadcast message based on a Bluetooth protocol, the BLE broadcast message of the type only allows other devices to scan the message to acquire information therein, but cannot initiate a Bluetooth connection request through the message, the embodiment of the invention does not need to establish Bluetooth pairing connection on two sides, and establishes Wi-Fi P2P connection through the BLE broadcast message, thereby realizing combined transmission of Bluetooth and Wi-Fi P2P, and meanwhile, compared with the scheme of establishing Bluetooth connection first and then establishing Wi-Fi P2P connection information through Bluetooth channel interaction, the scheme avoids a large amount of time consumed by Bluetooth pairing connection, and simplifies the process of establishing Wi-Fi P2P connection.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 2A, an embodiment of the present invention provides an interactive system for establishing a communication connection and data transmission, including: a first terminal 10 and a second terminal 20.

The first terminal 10 is configured to determine Wi-Fi P2P MAC address information according to the scanned BLE broadcast packet, where the type of the BLE broadcast packet is a scannable non-directional type; establishing Wi-Fi P2P connection with opposite-end equipment through the Wi-Fi P2P MAC address information; and carrying out data transmission with the opposite terminal equipment through the established Wi-Fi P2P connection.

A second terminal 20, configured to send a BLE broadcast packet including a MAC address used for determining Wi-Fi P2P, where a type of the BLE broadcast packet is a scannable non-directional type; after receiving a request for establishing Wi-Fi P2P connection sent by opposite-end equipment, sending a response for agreeing to establish Wi-Fi P2P connection to the opposite-end equipment; and carrying out data transmission with the opposite terminal equipment through the established Wi-Fi P2P connection.

Through the scheme, the first terminal determines the Wi-Fi P2P MAC address of the second terminal through a BLE broadcast message interacting with the second terminal, establishes Wi-Fi P2P connection with the second terminal according to the Wi-Fi P2P MAC address, and performs data transmission with the second terminal through Wi-Fi P2P connection, a scheme of combined transmission of Bluetooth and Wi-Fi P2P is provided, further, due to the fact that the BLE broadcast message is of a scannable non-directional type, Wi-Fi P2P connection can be established through the BLE broadcast message without establishing Bluetooth pairing connection between the first terminal and the second terminal, time consumed by Bluetooth pairing connection is avoided, and the process of establishing Wi-Fi P2P connection is simplified.

In the embodiments of the present invention, there are various ways for triggering the first terminal to scan the BLE broadcast packet containing the preset UUID information or triggering the second terminal to send the BLE broadcast containing the preset UUID information, and the following examples are specifically described below:

the first triggering mode is as follows: triggering by identifying a function switch supporting combined transmission of Bluetooth and Wi-Fi P2P;

the terminal is integrated with a function switch with an identifier supporting combined transmission of Bluetooth and Wi-Fi P2P, after the function switch is turned on, a command of combined transmission of Bluetooth and Wi-Fi P2P is triggered, after the terminal receives the command, the Bluetooth function and the WLAN function are started, and Bluetooth scanning and Wi-Fi P2P direct scanning are started.

And if the BLE broadcast message containing the preset UUID information is scanned through Bluetooth, determining the Wi-Fi P2P MAC address of the opposite terminal equipment according to the information in the BLE broadcast message, and establishing Wi-Fi P2P connection.

The function switch for identifying the combined transmission supporting the bluetooth and the Wi-Fi P2P has various display forms, such as:

the display mode is as follows: see fig. 1A or fig. 1B;

the function switch is set on a relevant display interface of the terminal, such as: the function switch of the combined transmission of the Bluetooth and the WLAN in FIG. 1A or FIG. 1B.

And a second display mode: see FIG. 2B;

In the pull-down menu shown in fig. 2B, a function switch for quickly turning on the Wi-Fi P2P joint transmission is provided, and clicking on the icon triggers an instruction for bluetooth and Wi-Fi P2P joint transmission.

And a second triggering mode: selecting a Bluetooth and Wi-Fi P2P combined transmission mode to trigger during data sharing;

when the file sharing is carried out, the mode of jointly transmitting through Bluetooth and Wi-Fi P2P in the file sharing mode is selected to start the Bluetooth and Wi-Fi P2P joint transmission.

For example, the following steps are carried out: if the user a holds the mobile terminal 1, the user B holds the mobile terminal 2, and the user a needs to share a file named "work" with the user B through the mobile terminal 1, the specific operation flow is as follows:

the user a selects a file named "work" on the mobile terminal 1, selects a sharing button of the file or presses the file package for a long time to trigger the mobile terminal 1 to display a sharing interface as shown in fig. 2C, wherein the file sharing mode includes bluetooth and Wi-FiP2P joint transmission, mail, information, WeChat and other modes. After the user A selects the combined transmission of the Bluetooth and the Wi-Fi P2P, the mobile terminal 1 informs the user A whether to use the combined transmission of the Bluetooth and the Wi-Fi P2P through a popup window as shown in FIG. 2D, and after the user A clicks 'OK', the mobile terminal 1 is triggered to start the combined transmission function of the Bluetooth and the Wi-Fi P2P.

Correspondingly, if the mobile terminal 2 needs to receive the work file in a bluetooth and Wi-Fi P2P joint transmission manner, the mobile terminal 2 also needs to start a bluetooth and Wi-Fi P2P joint transmission function, and the starting manner may refer to specific operation steps of the mobile terminal 1, which is not described herein again.

And starting a Bluetooth and Wi-Fi P2P combined transmission function, and establishing Wi-Fi P2P connection between the mobile terminal 1 and the mobile terminal 2 through a BLE broadcast message.

The embodiment of the invention is based on the application of the non-connected BLE, the non-connected BLE application depends on BLE broadcast, the party sending BLE broadcast messages is called Broadcaster, and the party monitoring the BLE broadcast messages is called Observer. The following describes an interactive process involved in establishing a communication connection and data transmission, which is provided by the present invention, by taking the first terminal as an Observer and the second terminal as a Broadcaster as an example.

BLE broadcast types are four: connectable non-directional broadcasts, connectable directional broadcasts, non-connectable non-directional broadcasts, and scannable non-directional broadcasts. Embodiments of the present invention are based on a fourth scannable non-directional broadcast, also known as a discoverable broadcast, that cannot be used to initiate a connection, but allows other devices to scan for the broadcast device. This means that the device can be found, either sending BLE broadcast messages or sending scan reply data in response to the scanned device, but not establishing a connection.

BLE broadcasts are through the interactive data flow of BLE broadcast message, there are two kinds of messages in the bluetooth low energy standard: the type of the message is determined by a channel where the message is transmitted, 3 broadcast channels and 37 data channels are specified in a low-power-consumption Bluetooth specification, and if the message is transmitted in the broadcast channels, the message is a broadcast message; if the data message is transmitted in the data channel, the data message is the data message.

The two types of messages have two completely different purposes, and the intelligent device utilizes the broadcast messages to discover and connect other devices. Once the connection is established, the data packet can only be sent to the connected peer device through the data channel. The difference between the two is that the data message can only be understood by two devices (master and slave) in the connection, while the broadcast message can be broadcast to a plurality of listening devices or only sent to a specific device.

As shown in fig. 3, a schematic structural diagram of a BLE broadcast message format according to an embodiment of the present invention is provided.

The BLE broadcast message comprises the following four parts:

preamble (Preamble): the broadcast channel is fixed to 10101010b, the data channel is 10101010bor01010101 b;

access Address: the broadcast channel is fixed to 0x8E89BED6, the data channel is a random value, different connections have different values, and the data channel is used between two devices after the connection is established;

CRC: CRC checking;

PDU: as shown in FIG. 4, the PDU includes a PDU Header and PDU Payload data;

as shown in fig. 5, the PDU Header includes a PDU Type (Type) for representing the Type of the BLE broadcast packet, and the PDU Type is described in detail below:

as shown in table 1 below, the PDU Type includes four Advertising types, two Scanning types, and one initializing Type, which are distinguished by 1byte data.

TABLE 1 BLE broadcast message-PDU Type in PDU Header

Wherein, the adapting type comprises: ADV _ IND is connectable non-directional broadcast, ADV _ DIRECT _ IND is connectable directional broadcast, ADV _ non _ IND is non-connectable non-directional broadcast, and ADV _ SCAN _ IND is scannable non-directional broadcast;

scanning types include: SCAN _ REQ indicating that a broadcaster can be requested to broadcast more information through the PDU when receiving broadcast data of ADV _ IND or ADV _ SCAN _ IND type; SCAN _ RSP, which means that after the broadcaster receives the SCAN _ REQ request, more data is transmitted to the opposite terminal equipment through the PDU response;

the initialization type is CONNECT _ REQ, which indicates that when receiving broadcast data of ADV _ IND or ADV _ DIRECT _ IND type, connection with the other party can be requested through the PDU;

The embodiment of the present invention uses a scannable non-directional ADV _ SCAN _ IND Type PDU Payload, the flag bit of PDU Type is 0110, and as shown in table 2, it is a structural schematic diagram of an ADV _ SCAN _ IND Type PDU Payload, where the maximum length of this Type PDU Payload data packet is 37 bytes, where AdvA is a broadcast device address part, which contains a broadcast sender's bluetooth MAC address, and 6 bytes, and AdvData is a PDU data part, which contains two parts, namely, significant (valid data) and non-significant (invalid data), and 31 bytes in total.

TABLE 2 BLE BROADCAST MESSAGE-PDU Payload of ADV _ SCAN _ IND type

AdvData is described in detail below, and includes, but is not limited to, the following:

1, a valid data portion;

the valid Data part contains a number of broadcast Data units called AD Structure, which contains Length and Data. As shown in fig. 6, the composition of the AD Structure includes, but is not limited to, the following:

1) the Length indicates the Length of Data included after the Length in the AD Structure, that is, the Length of Data.

2) AD Type, which indicates the Type of content represented by AD Data, such as device name, UUID, etc.;

3) AD Data, specific Data content.

For example, the content 020106 of an AD Structure is 02 for Len (indicating that the next 2 bytes of content all belong to AD Structure 1), 01 for AD Type, and 06 for AD Data.

2, invalid data portion;

the length of AdvData in PDU Payload must be 31 bytes, if the valid data part is less than 31 bytes, then it is complemented with 0, and the data in this part is invalid.

The AD types involved in the embodiments of the present invention include, but are not limited to, the following types, which are described below:

type 1: incomplete 16-bit UUID information;

an important concept in BLE applications is UUID, which identifies bluetooth services and communication feature access attributes, with different access methods being used for different bluetooth services and attributes.

Three definitions of the service UUID format in the bluetooth broadcast are 16-bit UUID, 32-bit UUID and 128-bit UUID. The difference between complete and incomplete is that the device supports various service UUIDs, but only broadcasting a part of the services is called incomplete, and the embodiment of the invention adds a self-defined service in a broadcast data packet, so that the monitoring broadcaster Observer can determine an available device supporting combined transmission of bluetooth and Wi-Fi P2P by judging whether a scanned BLE broadcast message carries UUID information corresponding to the self-defined service.

In the embodiment of the invention, 0x02 represents incomplete 16-bit UUID information, and if the AD Type is 02, the content of ADData is incomplete UUID information.

Such as: the Service name defined by the invention is My _ Service _ UUID, and if the My _ Service _ UUID generated by using the UUID random generator is E953, when the UUID obtained by analyzing the received BLE broadcast message contains E953, the terminal broadcasting the BLE broadcast message is a valid terminal, namely a terminal supporting Bluetooth and Wi-Fi P2P combined transmission control.

For example, the following steps are carried out: the AD Structure 1 in the BLE broadcast message received by the first terminal is 030253E 9, where length is 03, 3 bytes after length belong to the AD Structure 1, AD Type is 02, the content of AD Data is UUID information, and the corresponding UUID information is E953, that is, My _ Service _ UUID, then the first terminal determines that the terminal broadcasting the BLE broadcast message is a terminal supporting bluetooth and Wi-Fi P2P joint transmission control.

It should be noted that the My _ Service _ UUID E953 is only an example, any value representing meaning or type is not limited to a fixed real number, and any value or length combination meeting the requirement of the condition is suitable for the present invention.

Type 2: a device name;

in the embodiment of the invention, 0x08 represents equipment abbreviation, 0x09 represents equipment full name, correspondingly, AD Data is a character string of names, and if AD Type is 08, the AD Data is the abbreviation of the names of the equipment; if the AD Type is 09, the AD Data device is called fully, and the added part is to enable the broadcast monitor Observer to obtain the device name of the Broadcaster, so as to display the device name, which is convenient for the user to view.

For example, the content of an AD Structure is 0E 09454 d 393330342046696E 646 d65, where Len is 0E (indicating that the contents of the next 14 bytes all belong to the AD Structure), AD Type is 09 for the device generic name, AD Data is 454 d 393330342046696E 646 d65 for 'E "M" 9 "3" 0 "4" space "F" i "n" d "M" E' (see ASCII code hexadecimal).

Type 3: customizing data;

in the embodiment of the invention, 0xFF represents vendor self-defined data, the first two bytes represent vendor ID, the default is 6F4D, and the rest are added according to requirements, so that the data content in the data can be self-defined.

The embodiment of the invention can represent the Wi-Fi P2PMAC address or the difference item of the Bluetooth MAC address and the Wi-Fi P2P MAC address of the broadcast sender Broadcaster through the custom data. That is, there are various ways for determining the Wi-Fi P2P MAC address information contained in the custom data, which are illustrated below:

The first method is as follows: the user-defined data comprises a difference item of a Bluetooth MAC address and a Wi-Fi P2P MAC address;

fig. 7A is a schematic diagram showing the bluetooth MAC address and the WLAN MAC address of terminal a.

Taking the terminal A as an example, the WLAN MAC address of the terminal A is EC: D0:9F: C6:50:8B, the Bluetooth address of the terminal A is EC: D0:9F: C6:50:8A, the difference item is 8A, the self-defined data part is the difference item 8A, and the content of the AdvData in the PDU payload is 04FF 4D 6F 8A;

fig. 7B is a diagram illustrating the bluetooth MAC address and the WLAN MAC address of the terminal B.

Taking terminal B as an example, the WLAN MAC address of terminal B is 10:44:00: a5: DE: CD, the bluetooth MAC address of terminal B is 10:44:00: a5: CF:65, if the difference item is the data portion defined here is the difference item DE CD, the content of AdvData in the pdupyload is 05FF 4D 6F DE CD;

correspondingly, the broadcast receiver Observer analyzes the received BLE broadcast message, determines the Bluetooth MAC address of the broadcast sender Broadcaster through the AdvA in the PDUpayload, determines the difference item between the Bluetooth MAC address of the broadcast sender Broadcaster and the WLAN MAC address through the AdvData in the PDU payload, and determines the WLAN MAC address of the broadcast sender Broadcaster according to the analyzed Bluetooth MAC address and the difference item between the Bluetooth MAC address and the WLAN MAC address.

It should be noted that, here, the WLAN MAC address is merely used as an example, and in the BLE broadcast message in the embodiment of the present invention, information capable of determining the Wi-Fi P2P MAC address is placed.

For example, the content of the PDU payload in the BLE broadcast message received by the broadcast receiver Observer is 104400 a5 CF 6505 FF 4D 6F DE CD, the first 6 bytes are AdvA, that is, the bluetooth MAC address 104400 a5 CF65, and the next content is 05 FF 4D 6F DE CD whose bytes are AdvData, so that part of the content can know that the difference item between the bluetooth MAC address and the Wi-Fi P2P MAC address is DE CD, and the Wi-Fi P2P MAC address 10:44:00: a5: DE CD of the broadcast sender Broadcaster is determined according to the analyzed bluetooth MAC address and the difference item between the two.

The second method comprises the following steps: the self-defining data comprises a Wi-Fi P2P MAC address;

if the BLE broadcast message contains a complete Wi-Fi P2P MAC address, the broadcast receiver Observer determines the Wi-Fi P2P MAC address of the broadcast sender Broadcaster according to the Wi-Fi P2P MAC address information obtained by analyzing the BLE broadcast message.

For example, the content of the PDU payload in the BLE broadcast message received by the broadcast receiver Observer is 104400 a5 CF 6509 FF 4D 6F 104400 a5 DE CD, and the Wi-Fi P2P MAC address 104400 a5 DE CD of the broadcast sender Broadcaster can be determined according to the content of the AdvData.

According to the embodiment of the invention, the first terminal and the second terminal establish Wi-Fi P2P connection through interactive BLE broadcast messages.

step 804, the first terminal initiates a Wi-Fi P2P connection request to the opposite terminal equipment according to the Wi-Fi P2P MAC address;

step 805, the first terminal receives a response that the opposite terminal equipment agrees to establish Wi-Fi P2P connection;

and step 806, the first terminal performs data transmission with the opposite terminal device through the Wi-Fi P2P connection.

It should be noted that, the first terminal determines a Wi-Fi P2P MAC address and an equipment name of an opposite-end equipment according to a received BLE broadcast message containing preset UUID information, adds the equipment name of the opposite-end equipment to a list interface locally representing connectable equipment, and after a user clicks and selects the equipment, the first terminal initiates a request for establishing Wi-Fi P2P connection according to a Wi-Fi P2P MAC address of the equipment, and when receiving a response agreeing to establish Wi-Fi P2P connection sent by the equipment (i.e., an opposite-end equipment establishing Wi-Fi P2P connection), the first terminal and the equipment successfully establish Wi-Fi P2P connection.

As shown in fig. 9, a flowchart of a method for establishing a communication connection and a data transmission at a second terminal according to an embodiment of the present invention includes the following steps;

step 900, a function switch of the combined transmission of the Bluetooth and the Wi-Fi P2P of the second terminal is turned on, and the Bluetooth and WLAN functions are turned on;

step 901, a second terminal sends a BLE broadcast message;

step 902, the second terminal determines whether a request for establishing Wi-Fi P2P connection initiated by the peer device is received; if so, go to step 903, otherwise exit the flow.

Step 903, the second terminal sends a response of agreeing to establish Wi-Fi P2P connection to the opposite terminal equipment;

and step 904, the second terminal performs data transmission with the opposite terminal device through Wi-Fi P2P connection.

It should be noted that the second terminal may periodically send BLE broadcast messages, and if the sent BLE broadcast messages are scanned by other terminals supporting bluetooth and Wi-Fi P2P joint transmission, the device names of the second terminal may be displayed on a list interface locally representing connectable devices. If the second terminal receives a request for establishing Wi-Fi P2P connection initiated by the opposite terminal device, a dialog box for informing the user whether to establish Wi-Fi P2P connection with the opposite terminal device is popped up, if the user clicks 'confirm', the second terminal can accept the connection request, and if the user clicks 'cancel', the second terminal rejects the connection request. If the connection request is accepted, after the second terminal sends a response of agreeing to establish Wi-Fi P2P connection to the opposite terminal device, the second terminal can perform data transmission with the opposite terminal device through Wi-Fi P2P connection.
