Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Some words appearing hereinafter are explained:

1. In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, A and/or B, and can mean that A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

2. The Wi-Fi P2P, also called WLAN direct connection, can realize interconnection between terminals and high-speed data transmission under the condition of not having Wi-Fi hot spots and cellular networks.

3. In the embodiment of the invention, the terms "first terminal" and "second terminal" refer to intelligent equipment with Wi-Fi function and Bluetooth function, such as a mobile phone, a tablet, an intelligent camera, an intelligent printer and the like.

4. In the embodiment of the invention, the term 'BLE' refers to a key technology proposed by Bluetooth 4.0 specification, is used for discovering equipment and performing some simple communication, has the advantages of low running power consumption, low standby power consumption and the like, but has a relatively low transmission rate, and is not suitable for transmitting a large number of data streams.

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

The application scenario described in the embodiment of the present invention is for more clearly describing the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention, and as a person of ordinary skill in the art can know that the technical solution provided by the embodiment of the present invention is applicable to similar technical problems as the new application scenario appears. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

The following describes the scheme of the invention by taking a mobile phone as an example:

Suppose that the two mobile phones share the file by using a mode of combined transmission of Bluetooth and Wi-Fi, wherein the file sender is a mobile terminal 1, and the file receiver is a mobile terminal 2. The mobile terminal 1 and the mobile terminal 2 are respectively provided with a Bluetooth and Wi-Fi P2P joint transmission function switch, and when the function switch is clicked, the Bluetooth function and the WLAN function are started at the same time, wherein the WLAN function comprises Wi-Fi hot spot connection and Wi-Fi P2P connection.

After the WLAN function is turned on, the mobile terminal 1 determines, through the scanned BLE broadcast packet, that the mobile terminal supporting the bluetooth and Wi-Fi P2P joint transmission, for example, if the scanned BLE broadcast packet includes preset UUID information indicating that the bluetooth and Wi-Fi P2P joint transmission is supported, it is determined that the mobile terminal sending the BLE broadcast packet has the bluetooth and Wi-Fi P2P joint transmission function. The mobile terminal 1 analyzes the scanned BLE broadcast message containing preset UUID information to obtain the device name of the mobile terminal for sending the BLE broadcast message, and adds the device name into a local device list supporting Bluetooth and Wi-Fi P2P joint transmission.

For example, referring to fig. 1A, the mobile terminal 1 parses a scanned BLE broadcast message including preset UUID information, and the parsed device name is "mobile terminal 2", and then the mobile terminal 1 adds "mobile terminal 2" to a local "i search connectable device" 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 Wi-Fi P2P connection establishment between mobile terminal 1 and mobile terminal 2 is completed. The mobile terminal 1 performs data transmission, i.e. file sharing, with the peer device through a Wi-Fi P2P connection, and in the above example, the mobile terminal 2 is the peer device of the mobile terminal 1, and the whole process is described below with the angle of the mobile terminal 2:

Correspondingly, after clicking a function switch for turning on the combined transmission of the Bluetooth and the Wi-Fi P2P on the mobile terminal 2, simultaneously turning on the Bluetooth and the WLAN on the mobile terminal 2, after turning on the WLAN, the mobile terminal 2 sends a BLE broadcast message containing preset UUID information, when the mobile terminal 2 receives a request for establishing Wi-Fi P2P connection sent by the mobile terminal 1, if a user clicks an approval button, the mobile terminal 2 sends an approval response for establishing Wi-Fi P2P connection 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 mobile terminal 1 is used as an initiator for establishing Wi-Fi P2P connection, and the mobile terminal 2 is used as a peer device for passively waiting for Wi-Fi P2P connection, which is only an example, and the embodiments of the present invention are not limited to the operations of any one party as all functions integrated on the mobile terminal. I.e. in this procedure, the mobile terminal 2 may also act as an initiator initiating the establishment of a Wi-Fi P2P connection, and the mobile terminal 1 as a recipient receiving the request for establishing a Wi-Fi P2P connection.

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

Because the BLE broadcast message used in the embodiment of the invention is a BLE broadcast message of a scannable non-directional type based on a Bluetooth protocol, and the BLE broadcast message of the type only allows other equipment to scan the message to acquire information therein and can not initiate a Bluetooth connection request through the message, bluetooth pairing connection is not required to be established on two sides, wi-Fi P2P connection is established through the BLE broadcast message, joint transmission of Bluetooth and Wi-Fi P2P is realized, and meanwhile, compared with the scheme that Bluetooth connection is established firstly and Wi-Fi P2P connection information is established through Bluetooth channel interaction, the scheme avoids a great amount of time consumed by Bluetooth pairing connection and simplifies the flow of establishing Wi-Fi P2P connection.

Embodiments of the invention are described in further detail below with reference to the drawings.

As shown in fig. 2A, an interactive system for establishing a communication connection and transmitting data is provided in an embodiment of the present invention, which includes 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 a scanned BLE broadcast packet, where the type of the BLE broadcast packet is a scannable non-directional type, establish Wi-Fi P2P connection with a peer device through the Wi-Fi P2P MAC address information, and perform data transmission with the peer device through the established Wi-Fi P2P connection.

The second terminal 20 is configured to send a BLE broadcast packet including a Wi-Fi P2P MAC address, where the type of the BLE broadcast packet is a scannable non-directional type, send a response to the peer device agreeing to establish a Wi-Fi P2P connection after receiving a request to establish the Wi-Fi P2P connection sent by the peer device, and perform data transmission with the peer device 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 the BLE broadcast message interacted 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 the Wi-Fi P2P connection, so that the scheme of combined transmission of Bluetooth and Wi-Fi P2P is provided, and further, the 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 because the BLE broadcast message is of a scannable non-directional type, so that the time consumed by Bluetooth pairing connection is avoided, and the flow for establishing Wi-Fi P2P connection is simplified.

In the embodiment of the present invention, there are various ways for triggering the first terminal to scan a BLE broadcast message containing preset UUID information or triggering the second terminal to send a BLE broadcast containing preset UUID information, which are specifically described below by way of example:

Triggering by identifying a function switch supporting the joint transmission of Bluetooth and Wi-Fi P2P;

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

If the BLE broadcast message containing the preset UUID information is scanned through Bluetooth, determining a 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 supporting the combined transmission of Bluetooth and Wi-Fi P2P is provided with various display modes, such as:

Display mode one, see fig. 1A or fig. 1B;

The function switch is set on a certain relevant display interface of the terminal, such as the function switch of the bluetooth and WLAN combined transmission in fig. 1A or fig. 1B.

Display mode II, see FIG. 2B;

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

The second triggering mode is to select a mode of combining Bluetooth and Wi-Fi P2P transmission for triggering during data sharing;

When the file sharing is carried out, the mode of the combined transmission of Bluetooth and Wi-Fi P2P in the file sharing mode is selected to start the combined transmission of Bluetooth and Wi-Fi P2P.

For example, if the user a holds the mobile terminal 1 and the user B holds the mobile terminal 2, the user a will share the file named "work" with the user B through the mobile terminal 1, and the specific operation flow is as follows:

A, a user selects a file named as work on the mobile terminal 1, and 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 shown in fig. 2C, wherein a file sharing mode comprises modes of Bluetooth and Wi-Fi P2P joint transmission, mail, information, weChat and the like. After the user A selects the combination transmission of Bluetooth and Wi-Fi P2P, the mobile terminal 1 informs the user A whether to use the combination transmission of Bluetooth and Wi-Fi P2P through a popup window shown in fig. 2D, and after the user A clicks 'determining', the mobile terminal 1 is triggered to start the combination transmission function of Bluetooth and Wi-Fi P2P.

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

And starting the Bluetooth and Wi-Fi P2P joint transmission function to establish Wi-Fi P2P connection through BLE broadcast messages by the mobile terminal 1 and the mobile terminal 2.

The embodiment of the invention is based on the application of non-connected BLE, the non-connected BLE application depends on BLE broadcasting, the party sending the BLE broadcasting message is called Broadcaster (broadcaster), and the party monitoring the BLE broadcasting message is called Observer (Observer). The interactive flow related to establishing communication connection and data transmission provided by the invention is described below by taking the first terminal as an Observer and the second terminal as Broadcaster as an example.

There are four types of BLE broadcast, connectible non-directional broadcast, connectible directional broadcast, non-connectible non-directional broadcast, and scannable non-directional broadcast. Embodiments of the present invention are based on a fourth scannable non-directional broadcast, also known as a discoverable broadcast, which cannot be used to initiate a connection, but allows other devices to scan the broadcast device. This means that the device can be found to send either BLE broadcast messages or scan response data in response to scanned devices, but cannot establish a connection.

The BLE broadcasts the interactive data stream of the message through the BLE, and the low-power Bluetooth specification comprises two types of messages, namely a broadcast message and a data message, wherein 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 the low-power Bluetooth specification, if the message is transmitted in the broadcast channel, the message is broadcast, and if the message is transmitted in the data channel, the message is data message.

The two types of messaging has two completely different purposes, and the intelligent equipment utilizes the broadcast message to discover and connect with other equipment. Once the connection is established, data messages can only be sent to the connected peer device over the data channel. The difference is that the data message can only be understood by two devices (master, slave) in the connection, whereas the broadcast message can be broadcast to several listening devices or only sent to a specific device.

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

The BLE broadcast message includes the following four parts:

Preamble (in the introduction), the broadcast channel is fixed to 10101010b, and the data channel is 10101010b or01010101b;

ACCESS ADDRESS (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 connection establishment;

CRC, CRC check;

As shown in fig. 4, the PDU includes a PDU Header and PDU Payload data;

The PDU Header includes a PDU Type (Type) as shown in fig. 5, which is used for characterizing the Type of BLE broadcast message, and the PDU Type is described in detail below:

as shown in table 1 below, the PDU Type includes four advertisement types, two Scanning types, and one INITIATING (initialization) Type, which are distinguished by 1byte data.

TABLE 1 BLE broadcast message- -PDU Type in PDU Header

The advertisement type comprises that ADV_IND is connectible non-directional broadcast, ADV_DIRECT_IND is connectible directional broadcast, ADV_ NONCONN _IND is non-connectible non-directional broadcast and ADV_SCAN_IND is scannable non-directional broadcast;

Scanning types include SCAN_REQ, which means that when broadcast data of the ADV_IND or ADV_SCAN_IND type is received, a broadcaster can be requested to broadcast more information through the PDU; scaN_RSP means that after the broadcaster receives the SCAN_REQ request, more data is transmitted to the opposite terminal equipment through the PDU response;

INITIATING is of the connect_req type, indicating that when broadcast data of the adv_ind or adv_direct_ind type is received, a connection can be requested to be established with the partner through the PDU;

in the embodiment of the invention, a scannable non-directional PDU Payload of the adv_scan_ind Type is used, the flag bit of the PDU Type is 0110, the following table 2 shows a schematic structure of the PDU Payload of the adv_scan_ind Type, and the maximum length of the PDU Payload packet of the Type is 37 bytes, where AdvA is a broadcasting device address part, including a bluetooth MAC address of a broadcasting sender, is 6 bytes, advData is a PDU data part, including two parts of significant (valid data) and non-significant (invalid data), and is 31 bytes in total.

TABLE 2 PDU Payload of BLE broadcast message-ADV_SCAN_IND type

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

1, a valid data portion;

The active Data part contains several broadcast Data units called AD structures, which contain Length and Data. As shown in fig. 6, the composition of the AD Structure includes, but is not limited to, the following:

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

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

3) AD Data, specific Data content.

For example, content 02 01 06 of a certain AD Structure, len is 02 (indicating that the content of the next 2 bytes belongs to this AD Structure 1), AD Type is 01, and AD Data is 06.

2, Invalidating the data portion;

AdvData in the PDU Payload must be 31 bytes in length, and if the valid data portion is less than 31 bytes, it is complemented with 0, and this portion of data 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 16bit UUID information;

an important concept in BLE applications is UUID, which is used to identify bluetooth services and access attributes of communication features, and different bluetooth services and attributes use different access methods.

The definition of the service UUID format in bluetooth broadcast has three kinds of 16bit UUID, 32bit UUID and 128bit UUID. The difference between complete and incomplete is that the device supports a plurality of service UUIDs, but only a part of the services are not complete, and the embodiment of the invention adds the self-defined services in the broadcast data packet, so that the monitoring broadcaster Observer can determine the available device supporting the combined transmission of Bluetooth and Wi-Fi P2P by judging whether the scanned BLE broadcast message carries UUID information corresponding to the self-defined services.

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

For example, the Service name of the user-defined method is My_Service_UUID, and if My_Service_UUID generated by using a UUID random generator is E953, if the UUID obtained by analyzing the received BLE broadcast message contains E953, the terminal broadcasting the BLE broadcast message is an effective terminal, namely a terminal supporting the joint transmission control of Bluetooth and Wi-Fi P2P.

For example, the first terminal determines that the terminal broadcasting the BLE broadcast message is a terminal supporting bluetooth and Wi-Fi P2P joint transmission control, if the AD Structure 1 in the BLE broadcast message received by the first terminal is 03 0253E9, wherein the length is 03, which means that 3 bytes after the length belong to the AD Structure 1, the AD Type is 02, the content of the AD Data is UUID information, and the corresponding UUID information is E953, that is, my_service_uuid.

It should be noted that the above-mentioned value of my_service_uuid is E953 only for example, and any value representing meaning or type of the present invention is not limited to a fixed real number, and any value or combination of lengths satisfying the condition requirements is applicable to the present invention.

Type 2, device name;

In the embodiment of the invention, 0x08 represents equipment abbreviation, 0x09 represents equipment full scale, corresponding, AD Data is a character string of name, if AD Type is 08, the name of the AD Data equipment is abbreviated, if AD Type is 09, the AD Data equipment is full scale, and the part is added for broadcasting a device name of a broadcasting monitor user's Observer to obtain a device name of a transmitting broadcaster Broadcaster for displaying, so that the user can conveniently check.

For example, the content of an AD Structure is 0e 09 45 4d 39 33 30 34 20 46 69 6e 64 6d 65, where Len is 0E (meaning that the content of the next 14 bytes belongs to the AD Structure), AD Type is 09 stands for device full scale, and AD Data is 45 4d 39 33 30 34 20 46 69 6e 64 6d 65 stands for 'E "M"9"3"0"4" space "F" i "n" d "M" E' (see ASCII code hexadecimal).

Type 3, custom data;

in the embodiment 0xFF of the invention, vendor custom data is represented by the first two bytes, vendor ID is represented by the first two bytes, the default is 6F4D, and the rest is added according to the requirement, so that the data content in the vendor custom data can be customized.

The embodiment of the invention can characterize the difference item between the Wi-Fi P2P MAC address or 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 Wi-Fi P2P MAC address information contained in the custom data, and the following is exemplified:

the first mode is that the custom data comprises a difference item of a Bluetooth MAC address and a Wi-Fi P2P MAC address;

fig. 7A shows a schematic diagram of the bluetooth MAC address and WLAN MAC address of the 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 term is 8A, if the self-defined data part is 8A, the content of AdvData in the PDU payload is 04FF 4D 6F 8A;

Fig. 7B shows a schematic diagram of the bluetooth MAC address and WLAN MAC address of the terminal B.

Taking the terminal B as an example, the WLAN MAC address of the terminal B is 10:44:00:a5:de:cd, the bluetooth MAC address of the terminal B is 10:44:00:a5:cf:65, the difference term is that the data portion defined here is the difference term DE CD, and the content of AdvData in the PDU payload 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 AdvA in PDU payload, determines the difference item between the bluetooth MAC address and WLAN MAC address of the broadcast sender Broadcaster through AdvData in 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 WLAN MAC address.

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

For example, the content of PDU payload in the BLE broadcast message received by the broadcast receiver Observer is 10 44 00 A5 CF 65 05 FF 4D 6F DE CD, the first 6 bytes are AdvA, that is, bluetooth MAC address 10 44 00 A5 CF 65, and the later is content 05 FF 4D 6F DE CD with byte AdvData, so that part of the content can know that the difference term between the bluetooth MAC address and the Wi-Fi P2P MAC address is DE CD, and then the Wi-Fi P2P MAC address 10:44:00:a5:de:cd of the broadcast sender Broadcaster is determined according to the parsed bluetooth MAC address and the difference term between the two.

The second mode is that the custom data contains 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 Wi-Fi P2P MAC address information obtained by parsing the BLE broadcast message.

For example, the content of PDU payload in the BLE broadcast message received by the broadcast receiver Observer is 10 44 00 A5 CF 65 09 FF 4D 6F 10 44 00 A5 DE CD, and the Wi-Fi P2P MAC address 10 44 00 A5 DE CD of the broadcast sender Broadcaster can be determined according to the content of AdvData.

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

Fig. 8 is a schematic flow chart of a method for establishing a communication connection and transmitting data at a first terminal according to an embodiment of the present invention, which includes the following steps;

step 800, turning on a function switch of the Bluetooth and Wi-Fi P2P joint transmission of the first terminal, and turning on Bluetooth and WLAN functions;

Step 801, a first terminal scans BLE broadcast messages sent by other devices;

Step 802, the first terminal judges whether the received BLE broadcast message contains preset UUID information, if yes, step 803 is executed, otherwise, the flow is exited;

Step 803, the first terminal determines a Wi-Fi P2P MAC address of the peer device according to the BLE broadcast message;

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 agrees to establish Wi-Fi P2P connection response when receiving the opposite terminal device;

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

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

Fig. 9 is a schematic flow chart of a method for establishing a communication connection and transmitting data at a second terminal according to an embodiment of the present invention, which includes the following steps;

Step 900, turning on a function switch for the combined transmission of Bluetooth and Wi-Fi P2P of the second terminal, and turning on the Bluetooth and WLAN functions;

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

Step 902, the second terminal judges whether a request for establishing Wi-Fi P2P connection initiated by the opposite terminal equipment is received, if yes, step 903 is executed, otherwise, the process is exited.

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

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

It should be noted that, when the second terminal sends the BLE broadcast message, the second terminal may send the BLE broadcast message periodically, and if the sent BLE broadcast message is scanned by other terminals supporting bluetooth and Wi-Fi P2P joint transmission, the device name of the second terminal is displayed on the list interface that locally indicates the connectable device. If the second terminal receives the Wi-Fi P2P connection establishment request initiated by the opposite terminal equipment, a dialog box for informing the user whether to establish Wi-Fi P2P connection with the opposite terminal equipment is popped up, if the user clicks 'determining', the second terminal can accept the connection request, and if the user clicks 'canceling', the second terminal refuses the connection request. If the connection request is accepted, the second terminal sends a response agreeing to establish Wi-Fi P2P connection to the opposite terminal equipment, and then the second terminal can perform data transmission with the opposite terminal equipment through Wi-Fi P2P connection.
