[ detailed description ] embodiments

For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.

The embodiment of the invention provides a method for establishing communication connection, which is suitable for a process of establishing communication connection by terminal equipment, when two pieces of equipment establish point-to-point communication connection, one piece of equipment in a searching state sends a request to other peripheral equipment in a broadcasting mode, then the other equipment waiting for receiving the request sends response information, the equipment selects equipment which is expected to be connected from the equipment sending the response information and establishes the communication connection, and due to the mode of establishing the communication connection by non-directional searching, the equipment which is required to be searched can be selected after the response of all the peripheral equipment is waited, so that the time for establishing the communication connection is increased. Therefore, in order to solve the problem, an embodiment of the present invention provides a method for establishing a communication connection, where the method is applied to a target role device having a function of receiving an established communication connection, and as shown in fig. 1, the method includes:

101. and sending own target device attribute information to the first designated device, so that the first designated device carries the acquired target device attribute information in the first detection message, and broadcasting the first detection message.

The first designated device is a device which initiates to establish communication connection in the two devices which establish communication connection. Each device needs its own device attribute information, which is identity information for distinguishing each device, and the attribute information may include device type information, designated identification information, attribute address, and other information. For example, the device attribute information may be a MAC (Media Access Control) address of the device, an SSID (Service Set Identifier) of the device.

The first probe message is request information sent by an initiating device for establishing communication connection to other devices when establishing communication connection with other devices.

The probe information is broadcast and transmitted in the form of data frames in the channel 1, the channel 6, or the channel 11. And the device attribute information is encapsulated in a data frame corresponding to the probe information based on the format of a P2P (peer to peer) protocol. Wherein the data frame includes three portions: a data frame header, a data portion, and a data frame trailer. The data frame head and the data frame tail comprise some control information, and the control information comprises address positioning and other network information of equipment for receiving the data frame; the data portion is a data body and carries main contents of the message, for example, in data corresponding to the probe information, the data frame header and the data frame trailer include address location information of a device that desires to establish a communication connection, and the data portion carries data information such as a request for the device to establish a communication connection and a communication transport protocol.

102. And when the first detection message is monitored, analyzing the attribute information of the target equipment from the first detection message.

Since the first probe message is transmitted in the form of a data frame, after the device monitors the first probe message, the device decompresses the monitored data frame of the first probe message, thereby analyzing the first device attribute information carried in the first probe message.

103. And when the analyzed target equipment attribute information is matched with the self equipment attribute information, replying a first detection response message to the first specified equipment.

It is supplementary noted that, when the analyzed target device attribute information does not match the device attribute information of the device, the device does not respond to the probe information and does not reply to the first specific device.

104. A communication connection is established with a first designated device.

Preferably, the communication connection in this embodiment means that the device establishes a peer-to-peer connection with the first specified device, and when establishing the peer-to-peer connection, it needs to determine role information of itself and role information of the first specified device, then performs interaction of identity authentication information between the devices, and establishes a wireless network connection according to a standard handshake protocol of Wi-Fi P2P according to the negotiated role. The determination of roles between devices and the operation of identity authentication follow the prior art.

The embodiment of the invention provides a method for establishing communication connection, which comprises the steps of sending own target equipment attribute information to first appointed equipment, enabling the first equipment to carry the acquired first equipment attribute information in a first detection message, broadcasting the first detection message, analyzing the target equipment attribute information from the first detection message by monitoring the first detection message sent by the appointed equipment for establishing the communication connection, and replying a first detection response message to the first appointed equipment when the analyzed target equipment attribute information is matched with the own equipment attribute information, thereby establishing point-to-point connection with the first appointed equipment. Compared with the prior art, when two devices establish Wi-Fi P2P connection, request information is sent in a non-directional mode, and the devices for establishing connection are selected from the request information after other devices respond. On the other hand, in the directional searching process provided by the embodiment of the invention, only the corresponding target device replies, so that the security of network connection is better protected in the process of establishing network connection.

Further, when the device establishes a Wi-Fi peer-to-peer connection with the first designated device, the devices establishing the connection can share network routing information of the connection thereof.

It should be noted that the terminal device that establishes the Wi-Fi peer-to-peer connection supports a concurrent mode in which the base station and the Wi-Fi P2P coexist, that is, the device does not need to be disconnected from the network access point during the process of establishing the Wi-Fi P2P, and does not need to be disconnected from the device that establishes the Wi-Fi P2P network connection during the wireless connection between the device and the network access point.

In a first implementation manner, the device sends information of its own connected network to a first designated device, and a flowchart of a method of the method is shown in fig. 2, and includes:

105. and sending routing information of equipment connection through an established Wi-Fi point-to-point communication mode so that the first specified equipment is connected with a wireless network corresponding to the routing information.

In a second implementation manner, a first designated device sends information of its own network connection to the device, and a flowchart of a method of the method is shown in fig. 3, and includes:

106. and receiving the routing information sent by the first appointed equipment through an established Wi-Fi point-to-point communication mode.

107. And connecting the wireless network corresponding to the routing information according to the received routing information.

By adopting any one of the two implementation manners, one of the two devices can be quickly connected to the wireless network established by the other device, and the whole process can be automatically completed without user intervention, so that after the Wi-Fi point-to-point connection between the two devices is established by adopting the communication connection method provided by the embodiment, even if one of the devices is taken away and exceeds the distance capable of realizing Wi-Fi point-to-point communication between the two devices, the communication between the two devices can be maintained in a wireless network form through shared routing information.

Further, in order to implement an operation of establishing a communication network connection by directional search, adding device attribute information to a first probe message monitored by the device, and based on this purpose, embodiments of the present invention provide a possible implementation manner, configuring a device attribute field in the probe message, where the device attribute field is used to carry target device attribute information, where the device attribute field includes:

an attribute address field to indicate a type of point-to-point communication.

A length indication field for indicating a length of the device address field.

Specifically, the device attribute field is as described in table 1:

TABLE 1

Each of the fields of the device attributes in table 1 above represents the following meaning: an Attribute address field (Attribute ID), which has a length of 1 byte and a fixed value of 3, and represents that the content is the Device ID content; a Length indication field (Length) having a Length of 2 bytes and a fixed value of 6 bits, which represents that the content of the device address is 6 bytes; a device address field having a length of 6 bytes, which represents a MAC address of a target device to be searched.

Further, with reference to the foregoing operation method, in order to enable the first specified device to obtain the target device attribute information, and with respect to sending the target device attribute information of itself to the first specified device, a possible implementation method provided in an embodiment of the present invention has a flow shown in fig. 4, and specifically includes:

201. and establishing a special communication connection with the first specified device according to a specified mode.

In a specific implementation process, according to a specified manner, there may be multiple implementation manners for establishing the dedicated communication connection with the first specified device.

For example, both the above-mentioned two devices that establish communication connection are provided with NFC (Near field communication) chips that have a role of allowing contactless data exchange, transmission between electronic devices within a range of 20 cm from each other, and therefore, when the two devices that establish communication connection are close to each other, Near field communication connection is established, thereby performing data interaction.

Alternatively, both devices establishing a communication connection are provided with infrared communication functionality, wherein this communication is used in short-range data exchange. When the infrared communication functions of the initiating device and the target device are both started, the target device radiates infrared waves outwards, the infrared waves carry device attribute information of the target device, and then the infrared communication function of the initiating device receives the infrared waves to realize data transmission interaction.

Or, the two devices establishing connection start the bluetooth function, pair through bluetooth, and then use the bluetooth function to perform data interaction. Wherein, the bluetooth function is also used in short-distance data interaction.

It should be noted that the above examples are only three specific implementations of establishing the dedicated communication connection with the first designated device in a designated manner, where the manners of establishing the dedicated communication connection with the first designated device in the designated manner include near field communication, infrared communication, and bluetooth communication, but are not limited to these three manners.

202. Transmitting the target device attribute information of itself to the first specified device through a dedicated channel.

Further, a certain time is required for information transmission, and in the information transmission process, there is a problem that the first specified device does not receive the first probe response message replied by the device due to some reasons, so that the device and the first device cannot establish a communication connection, which is a possible solution provided by the embodiment of the present invention for this problem, as shown in fig. 5, specifically includes:

108. and negotiating and establishing the required equipment role information when the Wi-Fi point-to-point connection is established through the special channel.

Specifically, a process of establishing device role information required when a Wi-Fi peer-to-peer connection is established through dedicated channel negotiation is illustrated, where the device is a target device and the first designated device is an initiating device for establishing a communication connection. The specific implementation process comprises the following steps: the initiating device and the target device interact through a dedicated channel to prepare a request command for starting the establishment of the Wi-Fi P2P network connection, then a network module in the initiating device sends hotspot information of a role of a Wi-Fi direct group owner (an initiator of Wi-FiP2P communication connection) to a processor of the device, the corresponding device transmits information of a role of a Wi-Fi P2P communication connection acceptor of the corresponding device to the initiating device through the dedicated channel, and a function module of the initiating device for establishing the dedicated channel receives the role information and sends the role information to the processor of the initiating device.

It should be noted that, if the function module of the initiating device that establishes the dedicated channel cannot perform signaling interaction with its own processor, the negotiation of the device role information may also be implemented by the target device; if the functional module of the target device for establishing the dedicated channel can not perform signaling interaction with the processor of the target device, the Wi-Fi P2P is directly ended, and the connection failure is prompted.

109. And after the negotiation of the device role information is completed, establishing point-to-point connection with the first appointed device based on the determined device role information.

Further, in combination with any one of the above methods for establishing a communication connection, the method may also be used in an initiating role device for establishing a communication connection, and based on this object, an embodiment of the present invention further provides another possible implementation manner, as shown in fig. 6, the method further includes:

301. and monitoring the target equipment attribute information of other specified equipment sent by other specified equipment.

Wherein, the other specified device is a target device of the two devices establishing communication connection.

The device monitors the target device attribute information of other designated devices sent by other designated devices, and can monitor the target device attribute information of other designated devices sent by other designated devices through a dedicated channel established by the device and other designated devices in a designated manner. The specific way of establishing the dedicated channel includes, but is not limited to, near field communication, infrared communication, and bluetooth communication.

302. And carrying the target equipment attribute information corresponding to the other specified equipment in second detection information, and broadcasting the second detection information.

The method of carrying the target device attribute information corresponding to other specified devices in the second probe message is the same as the method of carrying the target device attribute information of the device itself in the first probe message, and the device attribute field set in the second probe message has the same structure as the device attribute field in the first probe message, so that the redundancy is not redundant here.

Wherein, the second probe message is also broadcast in channel 1 or channel 6 or channel 11, 303, and when receiving the second probe response information replied by other specified devices, the second probe message establishes communication connection with the other specified devices

It should be noted that, in the above embodiments, steps 101 to 109 are the execution process of the device establishing a communication connection with the target receiving role device as the initiating role device as the target receiving role device for establishing a communication connection; and step 301 to step 303 are executed processes of initiating the establishment of the communication connection to other devices in the target reception role when the device is used as the device for establishing the communication connection initiating role, where the process of establishing the communication connection by the device as the target reception role device and the process of establishing the communication connection by the device as the initiating role device are two independent processes.

It should be noted that, in the embodiment of the present invention, the first designated device and the other designated devices that establish a communication connection with the execution device that executes any of the above embodiments may be the same designated device or different designated devices. When the first designated device and the other designated devices are the same designated device, it is assumed that the executing device and the first designated device (other designated devices) perform role exchange when establishing communication connection between the executing device of the above embodiment as a target receiving angle device and the first designated device (other designated devices) performing role initiation, that is, the first designated device serves as a target receiving role device and the executing device serves as an initiating role device. The executing device executes a process of establishing a communication connection as a target receiving role device, and when a role exchange occurs with the device establishing the communication connection, the executing device operates in the same manner as the manner of establishing the point-to-point connection after the role exchange.

The method for establishing communication connection based on the directional search is specifically described by taking the process of establishing connection relation between devices when a user realizes mobile printing as an example. Wherein the first designated device establishing the communication connection is an image forming device such as a printer; the target equipment is a mobile phone terminal. As shown in fig. 7, a schematic flow chart of establishing a communication connection between an image forming apparatus and a mobile phone terminal is shown, where the method specifically includes:

step 1, the mobile phone terminal sends own target device attribute information to the image forming device, so that the image forming device carries the acquired first device attribute information in a first detection message, and broadcasts the first detection message.

Step 1.1, establishing special communication connection with the image forming equipment according to a specified mode, wherein the specified mode comprises near field communication, infrared communication and Bluetooth communication.

And step 1.2, transmitting the own equipment attribute information of the mobile phone terminal to the image forming equipment through a dedicated channel.

And 2, when the mobile phone terminal monitors the first detection message, analyzing the attribute information of the target equipment from the first detection message.

And 3, when the target equipment attribute information analyzed by the mobile phone terminal is matched with the equipment attribute information of the mobile phone terminal, replying a first detection response message to the image forming equipment.

It is supplementary noted that, when the target device attribute information analyzed by the mobile phone terminal from the first probe message is not matched with the device attribute information of the mobile phone terminal, the mobile phone terminal does not reply to the probe information, and the mobile phone terminal and the image forming device do not establish a Wi-Fi peer-to-peer connection.

And 4, establishing point-to-point connection between the mobile phone terminal and the image forming equipment.

When the image forming apparatus does not receive the first probe response message replied by the mobile phone terminal for some reason, the method further comprises the following steps:

and 5, the mobile phone terminal and the image forming equipment negotiate through the special channel to establish the equipment role information required by the Wi-Fi point-to-point connection.

And 6, after the negotiation of the device role information is completed, establishing point-to-point connection with the image forming device based on the determined device role information.

And 7, the mobile phone terminal sends the routing information of the self connection through the established Wi-Fi point-to-point communication mode so that the image forming equipment is connected with a wireless network corresponding to the routing information.

And 8, receiving the routing information sent by the image equipment by the mobile phone terminal through the established Wi-Fi point-to-point communication mode.

And 9, connecting the wireless network corresponding to the routing information by the mobile phone terminal according to the received routing information.

It should be noted that this embodiment is only one specific implementation manner of the method for establishing a communication connection provided by the embodiment, and is not intended to limit the application.

The embodiment of the invention provides a method for establishing communication connection, which comprises the steps of sending own target equipment attribute information to first appointed equipment, enabling the first appointed equipment to carry the acquired first equipment attribute information in a first detection message, broadcasting the first detection message, analyzing the target equipment attribute information from the first detection message by monitoring the first detection message sent by the first appointed equipment for establishing the communication connection, and replying a first detection response message to the first appointed equipment when the analyzed target equipment attribute information is matched with the own equipment attribute information, thereby establishing point-to-point connection with the first appointed equipment. Compared with the prior art, when two devices establish Wi-Fi P2P connection, request information is sent in a non-directional mode, and the devices for establishing connection are selected from the request information after other devices respond. On the other hand, in the directional searching process provided by the embodiment of the invention, only the corresponding target device replies, so that the security of network connection is better protected in the process of establishing network connection.

Based on the above embodiment of establishing a connection relationship between devices when a user implements mobile printing, the mobile phone terminal device may also initiate information for establishing a communication connection to the image forming device, thereby establishing a connection. The mobile phone terminal is an initiating device for establishing connection, and the image forming device is a target device for establishing connection. As shown in fig. 8, a schematic flow chart of another possible implementation method is provided for the embodiment of the present invention, and the method further includes:

and step 10, monitoring the second target equipment attribute information sent by the image forming equipment by the mobile phone terminal.

The mobile phone terminal and the image forming equipment establish a special channel to monitor the equipment attribute information sent by the image forming equipment by using a designated mode of near field communication, infrared communication, Bluetooth communication and the like.

And step 20, the mobile phone terminal carries the equipment attribute information of the image forming equipment in second detection information and broadcasts the second detection information.

In this case, the method of carrying the device attribute information of the image forming device in the second probe message is the same as the method of carrying the device attribute information of the mobile phone terminal in the first probe message, and the device attribute field set in the second probe message has the same composition as the device attribute field in the first probe message, so that it is unnecessary here.

Wherein the second probe message is also broadcast transmitted in channel 1 or channel 6 or channel 11

And step 30, when receiving second detection response information replied by the image forming equipment, the mobile phone terminal establishes point-to-point communication connection with the image forming equipment.

In another embodiment, as shown in fig. 9, in step 104: the network connection in "establishing a network connection with the first specified device" may be a Wi-Fi connection, in addition to the "point-to-point connection" in the above-described embodiment; for example, the above-mentioned target device attribute information includes "SSID and password" of the router, and the first specified device and the router establish a Wi-Fi connection based on steps S101 to S103.

The method for establishing the Wi-Fi connection based on the directional search is further supplemented with the following description when the user realizes mobile printing:

step 1001.1, the handset establishes a dedicated communication connection with the image forming device in a specified manner, such as near field communication, infrared communication, bluetooth communication.

Step 1001.2, transmitting the "SSID and password" information of all the routers connected in the handset terminal itself to the image forming apparatus through the dedicated channel, and selecting the "SSID and password" of one of the available routers.

Preferably, one router with the strongest signal strength is selected as the target device, and the "SSID and password" of the router is used as the attribute information of the target device.

Step 1002, when the target device (the router with the strongest signal strength) monitors the first probe message, analyzing the attribute information of the target device from the first probe message.

Step 1003, when the target device (the router with the strongest signal strength) analyzes that the target device attribute information matches the own device attribute information, replying a first probe response message to the image forming device.

It is supplementary to be noted that, when the target device attribute information analyzed by the other router from the first probe message does not match the device attribute information of the other router, the other router does not reply to the probe information, and the other router does not establish a Wi-Fi connection with the image forming device.

Step 1004, the target device (the router with the strongest signal strength) establishes a Wi-Fi connection with the image forming device.

Other steps after establishing the Wi-Fi connection through the directional search provided by this embodiment are similar to the steps, methods, devices, and systems of this embodiment only by replacing "Wi-Fi connection" with "Wi-Fi peer-to-peer connection" on the basis of the above embodiment, and are not described again here.
