Detailed Description

The technical solution of the present application can be applied to various terminal devices (also referred to as user equipment) having an image display function, for example, a mobile phone, a bracelet, a tablet Computer, a notebook Computer, an Ultra-mobile Personal Computer (UMPC), a Personal Digital Assistant (PDA) device, a handheld device having a wireless communication function, a computing device, or other processing devices connected to a wireless modem, an in-vehicle device, a wearable device, and the like, and is not limited to a communication terminal.

Fig. 1 shows a schematic flow chart of a method 100 of establishing a connection according to the present application, as shown in fig. 1, the method 100 comprising:

the following describes a technical solution of the present application, taking pairing-free file sharing between any two terminals in the same trust terminal group as an example.

S110, the first terminal obtains trust information of a trust terminal group, the trust terminal group comprises at least one terminal including the first terminal, and any two terminals in the trust terminal group can be connected in a pairing-free mode.

Optionally, the first terminal obtains the trust information by logging in to the cloud

Specifically, the first terminal can log in the cloud end through the cloud end login information to obtain the trust information. The trust terminal group comprises at least one terminal. The terminals in the trust terminal group may include different terminals of the same user, or terminals of different family members in the same family (for example, terminals that log in the same cloud account), or terminals of relatives and friends of the same family user, which is not limited in this application. Any two terminals included in the trust terminal group can be connected in a pairing-free mode.

It should be noted that the pairing-free connection is made to the user, that is, the user is unaware of the connection process (e.g., the process of inputting the user name and the password) between the two terminals (e.g., the screen of the terminal does not pop up a box to the user, which is used to prompt the user to input the user name and the password). However, for two terminals, a pairing process is performed between the two terminals, and the pairing process may include an automatic pairing process (for example, a user name and a password do not need to be input by a user, but are automatically input), or a private pairing process, or the pairing process may be omitted.

After the first terminal logs in to the cloud, identification information (e.g., an example of trust information) of all terminals that have logged in to the cloud account may be obtained from the cloud. The identification information may be account information (e.g., cloud account information) shared by terminals in the trust terminal group, and the first terminal may know terminals included in the same trust terminal group (e.g., an example of the trust terminal group). The identification information may also be identification information set by the user for each terminal in the group of trusted terminals. This is not a limitation of the present application.

Optionally, the first terminal may further cache the trust information obtained from the cloud to a local for storage, that is, the device of the terminal in the trust terminal group and the identification information of the device may be determined on a list of the trust devices stored on the local terminal (for example, an example of the first terminal). This is not a limitation of the present application.

Optionally, the trust terminal group may also be created by a user, that is, the user may establish a trust terminal group on the first terminal, and add the identification information of the trusted terminal to the trust terminal group.

For example, a first terminal learns that a cloud account has logged in all of the terminal 1, the terminal 2, the terminal 3, and the terminal 4 by logging in a cloud, and then the first terminal determines that the terminal 1, the terminal 2, the terminal 3, and the terminal 4 are all trusted terminals, and further determines identification information of the four terminals.

It should be understood that the manner of acquiring the trust terminal group is described only by taking the above-mentioned several manners of acquiring the trust terminal group as examples, but the application is not limited thereto. The trust terminal group may also be obtained by other methods, which is not limited in this application.

For example, the terminal 1 (e.g., an instance of the first terminal) has determined the terminals in the same trust terminal group through step S110. When the terminal 1 in the trust terminal group opens the file sharing switch, the identification information of the terminals in the same trust terminal group, which are located near the terminal 1 and can be scanned, is displayed in the connectable device module, and the identification information of the terminals in the non-same trust terminal group, which can be scanned, is displayed in the available device module. As shown in fig. 2.

The terminals with the displayed identification information comprise terminals belonging to the same trust terminal group and also comprise terminals not belonging to the same trust terminal group. For terminals that do not belong to the same group of trusted terminals, the identification information of the terminal is only displayed in the available device module when the discoverable switch of the terminal is turned on and the terminal is within the discoverable distance range.

For the terminals belonging to the same trust terminal group, if the discoverable switches of the terminals in the same trust terminal group are turned off, the terminal 1 still displays the identification information of the terminals in the same trust terminal group which are not turned on and have discoverable switches in the connectable device module.

In order to facilitate the user to select the terminal, when the terminal 1 opens the file sharing switch, the identification information of the terminal capable of being scanned is displayed in an online state (for example, the identification information of the terminal capable of being scanned is displayed in a bright color) — for example, the identification information of the terminal 2 (for example, the identification information is Yangjun 'Ipad) and the identification information of the terminal 4 (for example, the identification information is L iuyang' Iphone) which are scanned are displayed in a bright color for informing the user that the terminal is currently in a connectable state, wherein the terminal 2 is a terminal in the same trust terminal group, and the terminal 4 is a terminal in a non-same trust terminal group.

For a terminal in the same trust terminal group, if the terminal cannot be scanned currently, the identification information of the terminal is displayed in a non-online state (for example, the identification information of the terminal which cannot be scanned is displayed in a dark color).

The user may attempt a connection, i.e. attempt to send a file to, the terminal with the dark display.

Alternatively, if the transmission is successful, it may be marked with a "√" symbol on the left side of the scanned terminal, as shown in fig. 3, to inform the user that the terminal is a device in the trusted group of terminals that is within a connectable range (i.e., a non-discoverable, but connectable terminal).

Alternatively, when the terminal displayed in a dark color cannot be connected after the attempt, it may be marked with "×" on the left side of the scanned terminal for informing the user that the terminal is a terminal in the trusted terminal group but is currently in a non-connectable state (i.e., is a non-discoverable, non-connectable terminal).

Optionally, for a terminal successfully connected after the connection attempt, the identification information of the terminal may also be displayed in an online state (for example, the identification information of the terminal that can be scanned is displayed in bright color); for a terminal that fails to connect after attempting a connection, the identification information of the terminal may also be displayed in an offline state (for example, the identification information of a terminal that cannot be scanned is displayed in a dark color). This is not a limitation of the present application.

Optionally, for a terminal that cannot be scanned currently in the same trust terminal group, the terminal may not be displayed in the connectable module (that is, all terminals in the trust terminal group are displayed in the connectable network module); terminals that have established a connection with other terminals in the group of trusted terminals (which cannot currently be scanned) may also be displayed on the connectable network module. This is not a limitation of the present application.

Optionally, the user may click the identification information of the terminal displayed in a dark color to attempt connection, or may perform background connection through a background application of the terminal, which is not limited in this application.

Alternatively, when the terminal 1 opens the file sharing switch, it is possible to scan terminals in a connectable range around by any wireless communication means. The present application does not limit the wireless communication method of the scanning terminal at all.

For a terminal scanned by using the Bluetooth low Energy, an icon can be marked on the right side of the identification information of the terminal, and the icon represents the terminal obtained by the Bluetooth low Energy scanning.

It should be understood that, the above describes the scanning manner of the connectable device by taking bluetooth low energy as an example to scan the surrounding connectable devices, but the present application is not limited thereto, and other scanning manners may also be adopted to perform scanning. This is not a limitation of the present application.

Alternatively, when the terminal 1 turns on the file sharing switch, the terminal starts scanning for surrounding terminals. The scanning mode may be a bluetooth scanning mode or a WiFi scanning mode, which is not limited in this application.

When the terminal transmits files with other terminals, a bluetooth transmission mode, an e-mail mode or a WiFi transmission mode can be adopted, which is not listed here. This is not a limitation of the present application.

And S120, the first terminal determines a second terminal according to the trust information.

Specifically, the first terminal may determine the terminals included in the trusted terminal group according to the trust information. And may in turn determine a terminal (e.g., a second terminal) with which to establish an unpaired connection.

S130, the first terminal sends a connection establishment request message to the second terminal, where the connection establishment request message is used to request establishment of a pairing-free connection with the second terminal.

Specifically, after the terminal 1 determines the identification information of the terminals in the trusted terminal group, the file data information may be sent to the second terminal (e.g., the terminals in the trusted terminal group). For example, the terminal 1 selects the bluetooth transmission mode to transmit the file data information to the terminal 2.

First, the user clicks the identification information of the corresponding terminal 2. For example, when a user clicks the identification information (for example, the identification information is Yangjun' Ipad) of the terminal 2 (for example, an example of the second terminal) in the same trust terminal group, the clicking action of the user triggers the terminal 1 to send a connection establishment request message to the terminal 2, where the connection establishment request message is used to indicate to the terminal 2 that the terminal 1 needs to perform pairing-free connection with the terminal 2 through a bluetooth module.

Optionally, the connection establishment request message carries at least one of device login information, cloud account information, and physical address information of the communication module of the terminal 1.

Specifically, the connection establishment request message carries at least one of device login information, cloud account information, and physical address information of the communication module of the terminal 1. After receiving the connection establishment request message sent by the terminal 1, the terminal 2 may determine the identification information of the terminal 1 according to that the connection establishment request message carries at least one of the device login information, the cloud account information, and the physical address information of the communication module of the terminal 1.

The connection establishment request message may be encrypted to prevent other terminals in the untrusted terminal group from sending the same connection establishment request message to the terminal 2, thereby preventing the terminal 2 from performing an erroneous authentication. Or, after any two terminals in the same trust terminal group send the connection establishment request message, mutual authentication can be performed to determine whether the two terminals belong to the same trust terminal group. The process of encryption or authentication described above may be referred to as a security check. The present application does not limit the manner of security verification.

S140, the second terminal receives a connection establishment request message sent by the first terminal, where the connection establishment request message is used to request establishment of a pairing-free connection with the second terminal.

S150, the second terminal determines whether the first terminal passes the authentication according to the connection establishment request message.

Optionally, the second terminal obtains trust information of a trust terminal group, the trust terminal group comprises at least one terminal including the first terminal, and any two terminals in the trust terminal group can be connected in a pairing-free manner; and the second terminal determines whether the first terminal passes the authentication or not according to the trust information of the trust terminal group and the connection establishment request message.

Specifically, after the terminal 2 receives the connection establishment request message sent by the terminal 1, it needs to determine whether the first terminal can pass authentication, that is, determine whether the first terminal is a terminal in the same trust terminal group.

The terminal 2 may determine the identification information of the terminal included in the trust terminal group according to the trust information of the trust terminal group by acquiring the trust information of the trust terminal group, and further determine the identification information of the terminal 1. Meanwhile, the terminal 2 determines the identification information of the terminal 1 corresponding to the connection establishment request information according to the connection establishment request message sent by the terminal 1, and when the identification information of the terminal 1 determined by the terminal 2 according to the trust information of the trust terminal group is consistent with the identification information of the terminal 1 determined according to the connection establishment request message, the terminal 2 further determines that the terminal 1 is a terminal in the same trust group. That is, the terminal 1 is authenticated by the terminal 2.

S160, after the first terminal passes the authentication of the second terminal, the second terminal establishes a pairing-free connection with the first terminal.

Specifically, after the terminal 1 is authenticated by the terminal 2, the terminal 2 determines to establish a pairing-free connection of a bluetooth module with the terminal 1. When the terminal 2 determines that the pairing-free connection of the bluetooth module with the terminal 1 is established, the pairing-free connection is established between the bluetooth module of the terminal 2 and the bluetooth module of the terminal 1, and after the pairing-free connection between the bluetooth module of the terminal 2 and the bluetooth module of the terminal 1 is successfully established, the file data information required to be sent by the terminal 2 is sent to the terminal 1 in a pairing-free bluetooth transmission mode.

Alternatively, if the terminal 1 fails the authentication of the terminal 2, the terminal 2 may reject the connection establishment request of the terminal 1, that is, the terminal 2 may not establish the pairing-free connection with the terminal 1.

Optionally, the terminals included in the group of trusted terminals may be updated.

It should be noted that the updating includes adding a new terminal to the trusted terminal group, and also includes deleting a terminal in the trusted terminal group (for example, deleting a terminal that has not established a connection with the terminal for a long time).

For different terminals included in a trust terminal group, for example, when for a terminal 1 and a terminal 2 in the trust terminal group, a first trust group is established on the terminal 1, and the first trust group includes a bluetooth headset terminal and a bracelet terminal; the second trust group is established on the terminal 2, the first trust group comprises a Bluetooth sound terminal and a bracelet terminal, and the bracelet terminal is the same as the bracelet terminal in the first trust group. When the terminal 2 deletes the bracelet terminal in the second trust group, the deletion operation of the terminal 2 does not affect the terminals included in the first trust group of the terminal 1. That is, when the terminal 1 and the terminal 2 log in the cloud for synchronization, the bracelet terminals in the first trust group stored in the cloud are not deleted because the bracelet terminals in the second trust group are deleted.

Optionally, a certain terminal in the same trust terminal group may add another terminal in the trust terminal group to the blacklist. For the terminal 1, the terminal 2, and the terminal 3 in the same trust group, for example, the terminal 1 adds the terminal 3 to a blacklist, at this time, when the terminal 3 requests to establish pairing-free connection with the terminal 1, because the terminal 3 is added to the blacklist by the terminal 1, the terminal 1 does not pass through the pairing-free connection request of the terminal 3, at this time, the terminal 1 performs a pop-up box to a user corresponding to the terminal 3, the pop-up box is used to prompt the user to input a password for pairing connection, and when the user corresponding to the terminal 3 correctly inputs the password, the terminal 1 establishes connection with the terminal 3.

When the terminal 1 requests to establish the pairing-free connection with the terminal 3, since the terminal 3 does not add the terminal 1 to the blacklist, the terminal 3 may further request the pairing-free connection with the terminal 1 through the pairing-free connection of the terminal 1 and establish the pairing-free connection with the terminal 1.

Optionally, when the terminal 1 adds the terminal 3 to the blacklist and when the terminal 1 synchronizes the blacklist information to the cloud, when another terminal (for example, the terminal 4) sharing a cloud login information with the terminal 1 logs in the cloud, the blacklist information is also synchronized to the local from the cloud with the terminal 4, that is, the terminal 4 can know the specific content of the blacklist information. That is, by logging into the cloud, the terminal 4 knows that the terminal 3 is blacklisted. Alternatively, for terminals in a group of trusted terminals, each terminal may establish a connection with some other external device.

The external device may be a terminal that does not have a login function. For example, the external device may be a terminal such as a bluetooth headset, a wireless router, or a bracelet.

For example, the terminal 1 in the trusted terminal group establishes a connection with an external device wireless router. For the terminal 2 or the terminal 3 in the same trust terminal group, the terminal 2 or the terminal 3 can establish pairing-free connection with the external device wireless router.

Also for example, the terminal 2 in the trusted terminal group establishes a connection with an external device, a bluetooth headset. For the terminal 1 or the terminal 3 in the same trust terminal group, the terminal 1 or the terminal 3 can establish pairing-free connection with the external device Bluetooth headset.

It should be noted that the terminal devices in the same trust terminal group may be any one of a mobile phone terminal, a handheld terminal, and a bracelet terminal. This is not a limitation of the present application.

Therefore, according to the method for establishing the connection, the first terminal firstly determines the terminals included in the trust terminal group, namely determines which terminals are trustable, and then the pairing-free connection is established between any two terminals in the trust terminal group. Thereby improving the user experience.

Fig. 4 shows a schematic flow diagram of a method 200 of establishing a connection according to the application, the method 200 comprising, as shown in fig. 4:

the following describes the technical solution of the present application by taking an example of pairing-free hotspot connection between any two terminals in the same trust terminal group.

S210, the first terminal obtains trust information of a trust terminal group, the trust terminal group comprises at least one terminal including the first terminal, and any two terminals in the trust terminal group can be connected in a pairing-free mode.

S220, the first terminal determines a second terminal according to the trust information.

S230, the first terminal sends a connection establishment request message to the second terminal, where the connection establishment request message is used to request establishment of a pairing-free connection with the second terminal.

Specifically, after the first terminal determines the identification information of the terminals in the trusted terminal group, a connection establishment request message may be sent to the second terminal (for example, the terminals in the trusted terminal group), where the connection establishment request message is used to request that an unpaired hotspot connection be established with the second terminal.

For example, the group of trusted terminals includes four terminals of the same user, namely terminal 1, terminal 2, terminal 3, and terminal 4.

When a terminal 1 (for example, an example of a first terminal) needs to establish a connection with a hotspot of another nearby terminal, a wireless network switch may be turned on, at this time, identification information of terminals in the same trust terminal group that are located in the terminal 1 and can be scanned will be displayed on a connectable hotspot module of a wireless network setting interface of the terminal 1, and identification information of terminals in a non-same trust terminal group that can be scanned will be displayed on an available network module of the wireless network setting interface of the terminal 1. As shown in fig. 5.

The terminals with the displayed identification information comprise terminals belonging to the same trust terminal group and also comprise terminals not belonging to the same trust terminal group. For terminals that do not belong to the same group of trusted terminals, the identification information of the terminal is only displayed in the available network module when the discoverable switch of the terminal is turned on and the terminal is within the discoverable distance range.

For example, the scanned identification information of the terminal 2 (for example, the identification information is Yangjun 'Iphone) and the scanned identification information of the terminal 3 (for example, the identification information is L iuyang' Ipad) are displayed in bright color for informing the user that the terminal is currently in a connectable state, wherein the terminal 2 is a terminal in the same trust terminal group, and the terminal 3 is a terminal in a non-same trust terminal group.

For terminals in the same trust terminal group, if the terminal cannot be scanned currently, the identification information of the terminal is displayed in an offline state (for example, the identification information of the terminal which cannot be scanned is displayed in a dark color). For example, the identification information of the terminals 4 in the same trust terminal group (for example, the identification information is Zhangjie' Iphone) is displayed in a dark color, so as to inform the user that the terminals belong to the same trust terminal group but are not scanned currently.

The user may attempt a connection to, i.e. attempt to establish a connection with, the terminal in the dark display.

Alternatively, if the connection is successful, it may be marked with a "√" symbol on the left side of the scanned terminal, as shown in fig. 6, to inform the user that the terminal is a device in the trusted group of terminals that is within a connectable range (i.e., a non-discoverable, but connectable terminal).

Alternatively, when the terminal 1 turns on the wireless network switch, a terminal in a connectable range around may be scanned through any wireless communication method. The present application does not limit the wireless communication method of the scanning terminal at all.

After the identification information of the connectable terminals is displayed in the connectable hotspot module, the terminal 1 (e.g., an instance of the first terminal) may perform pairing-free hotspot connection on the terminals in the same trusted terminal group in the connectable hotspot module.

First, a user clicks identification information of a corresponding terminal. For example, when a user clicks the identification information (Yangjun' Iphone) of the terminal 2 (for example, an example of the second terminal) in the same trust terminal group, the click action of the user triggers the terminal 1 to send a connection establishment request message to the terminal 2, where the connection establishment request message is used to indicate to the terminal 2 that the terminal 1 needs to perform pairing-free hotspot connection with the terminal 2.

The connection establishment request message may be encrypted to prevent other terminals in the untrusted terminal group from sending the same connection establishment request message to the terminal 2, thereby preventing the terminal 2 from performing an erroneous authentication. Or, after any two terminals in the same trust terminal group send the connection establishment request message, mutual authentication can be performed to determine whether the two terminals belong to the same trust terminal group. The process of encryption or authentication described above may be referred to as a security check. The present application does not limit the manner of security verification in any way.

S240, the second terminal receives a connection establishment request message sent by the first terminal, where the connection establishment request message is used to request establishment of a pairing-free connection with the second terminal.

S250, the second terminal determines whether the first terminal passes the authentication according to the connection establishment request message.

S260, after the first terminal passes the authentication of the second terminal, the second terminal establishes a pairing-free connection with the first terminal.

Specifically, after the terminal 1 is authenticated by the terminal 2, the terminal 2 determines to establish a pairing-free hotspot connection with the terminal 1. The terminal 2 immediately opens the hotspot according to the indication of the connection establishment request message, and sends the user name and the password of the hotspot to the terminal 1, so that the terminal 2 establishes pairing-free connection with the hotspot of the terminal 1, that is, the user can successfully establish connection with the hotspot of the terminal 2 without inputting the user name and the password of the hotspot of the terminal 2.

It should be noted that, the above description is only given by taking an example that a user triggers a terminal to be connected to turn on a hotspot switch by clicking identification information of the terminal to be connected, and sends a user name and a password corresponding to the hotspot to an opposite terminal, and a pairing-free connection with the terminal to be connected is performed, but the application is not limited thereto.

The pairing-free connection can also be performed with the terminal to be connected in other manners, for example, by sending a short message (for example, sending a short message) to the terminal to be connected, the terminal to be connected sends the user name and the password to the opposite terminal in the same manner as the short message, so that the pairing-free connection is established with the opposite terminal. This is not a limitation of the present application.

It should be further noted that the terminal devices in the same trust terminal group may be any one of a mobile phone terminal, a handheld terminal, and a bracelet terminal. This is not a limitation of the present application.

Another embodiment of the technical solution of the present application is explained below. Fig. 7 shows a schematic flow chart of a method 300 of establishing a connection according to another embodiment of the present application, the method 300 comprising, as shown in fig. 7:

s310, the first terminal device and the device to be connected are authenticated, so that the first terminal device is authenticated through the device to be connected.

And S320, the device to be connected and the first terminal device are authenticated so as to pass the authentication of the first terminal device. Next, steps S310 and S320 will be described by taking the first terminal as a mobile phone device and the device to be connected as a wireless router as an example.

By way of example and not limitation. For a wireless network of a family, when one family member (hereinafter referred to as a first user) first accesses the wireless network through a first terminal (for example, a first mobile phone device), it needs to enter a setting interface of a wireless local area network of a mobile phone and open the wireless network. After the wireless network is opened, the first mobile phone device starts to scan the wireless network around the location, and displays the name of the scanned wireless network in an available network module of a setting interface of the wireless network, and the available network module displays the name of the wireless network that can be scanned around currently, as shown in fig. 8.

The first user first clicks the name of the wireless network to be connected among the names of all the wireless networks displayed in the available network module. For example, a name of a wireless network to which a first user needs to connect is called WirelessNet, for a first mobile phone device which establishes a connection with the wireless network WirelessNet for the first time, after the first mobile phone device clicks the wireless network WirelessNet in an available network module, at this time, a wireless router receives a connection establishment request message sent by the first mobile phone device, the wireless router judges the connection establishment request message, determines that the first mobile phone device corresponding to the connection establishment request message establishes a connection with the wireless router for the first time, at this time, the wireless router triggers the first mobile phone device to prompt the first user to input a password of the wireless network WirelessNet through a display interface, and when the first user correctly inputs the password of the wireless network, the first mobile phone device can establish a connection with the wireless network. That is, the first mobile phone device successfully establishes a connection with the wireless router through authentication of the wireless router.

Further, for example, taking the first terminal as a mobile phone device and the device to be connected as a bluetooth device, steps S310 and S320 will be described.

By way of example and not limitation, a bluetooth device, which may be a bluetooth sound, is connected to a mobile phone device in a home. When one of the family members (hereinafter referred to as a "first user") establishes a connection with the bluetooth sound box through a first terminal (for example, a first mobile phone device) for the first time, the first user first turns on a switch of the bluetooth sound box to enable the bluetooth sound box to enter an operating mode. The first user enters the Bluetooth setting interface of the first mobile phone device and opens the Bluetooth function of the mobile phone, and the Bluetooth device capable of being connected at the moment is displayed in the available device module of the Bluetooth setting interface of the first mobile phone device.

The first user clicks a name corresponding to the bluetooth sound in the available device module, for example, the name of the bluetooth sound is "YOYO", the first user clicks "YOYO" in the available device module of the bluetooth setting interface, the bluetooth sound receives a connection establishment request message sent by the first mobile phone device, and the bluetooth sound determines that the first mobile phone device establishes a connection with the first mobile phone device for the first time according to the connection establishment request message. At this time, the bluetooth sound device may trigger the first mobile phone device to prompt the user to input the pairing password through the mobile phone screen, as shown in fig. 9. The password may be the initial password of the bluetooth sound. When the first user correctly inputs the pairing password of the Bluetooth sound equipment, the first user is successfully paired with the Bluetooth sound equipment, namely the first mobile phone device passes the authentication of the Bluetooth sound equipment.

S330, the first terminal obtains the first identification information.

By way of example and not limitation. Specifically, after the first terminal (e.g., first mobile phone device) first passes the authentication of the device to be connected (e.g., wireless router or bluetooth sound). The first terminal acquires first identification information.

For example, the first identification information may be information randomly generated by the first terminal.

Also for example, the first identification information may be information based on system configuration, that is, information that terminal devices in the same home know each other.

For another example, the first identification information may also be at least one of device login information, cloud account information, and physical address information of the communication module of the first terminal. This is not a limitation of the present application.

S340, the first terminal sends the first identifier information to the device to be connected, so that after receiving a connection establishment request message carrying the first identifier information sent by a second terminal, the device to be connected determines that the second terminal passes authentication according to the first identifier information, and establishes a connection with the second terminal.

And S350, the device to be connected receives the first identification information sent by the first terminal, and determines that the terminal device sending the message carrying the first identification information is the authenticated terminal device.

And S360, the second terminal sends a connection establishment request message to the equipment to be connected, wherein the connection establishment request message is used for indicating the second terminal to request to establish connection with the equipment to be connected, and the connection establishment request message carries the first identification information, and the first identification information is sent to the equipment to be connected by the first terminal which passes the authentication of the equipment to be connected.

S370, the to-be-connected device receives a connection establishment request message sent by the second terminal, where the connection establishment request message is used to indicate the second terminal to request to establish a connection with the to-be-connected device, and the connection establishment request message carries the first identifier information.

And S380, the device to be connected establishes connection with the second terminal according to the first identification information and the connection establishment request message.

For example, step S340 to step S380 will be described with the first terminal and the second terminal as mobile phone devices and the device to be connected as a wireless router as an example.

For example, but not limited to, for a wireless network of a family, after one member of the family accesses the wireless network (for example, the name of the wireless network is WirelessNet) through a first terminal (for example, a first mobile phone device), the first mobile phone device obtains first identification information, for example, the first identification information is information based on system configuration, that is, the first identification information is known by all mobile phone devices in the family, and the first identification information is device name information of the first mobile phone device, for example, the device name information of the first mobile phone device is L iujiang' Iphone.

The first mobile phone device sends the first identification information to the wireless router, so that when receiving a connection establishment request message carrying the first identification information and sent by other mobile phone devices (for example, a second mobile phone device) in a family for the first time, the wireless router establishes a connection between the second mobile phone device and the wireless router for the first time. The wireless router determines that the second mobile phone device is an authenticated device, namely a trusted mobile phone device, according to the first identification information carried in the connection establishment request message. At this point, the wireless router may allow the second handset device to establish a pairing-free connection, i.e., the second handset device may be able to access the wireless network without the user entering a username and password.

For the wireless network WirelessNet which authenticates the first mobile phone device, when the second mobile phone device clicks the wireless network WirelessNet in the network name displayed by the available network module, the wireless router receives a connection establishment request message which is sent by the second mobile phone device and carries the first identification information (L iujiang 'Iphone), and the wireless router determines that the second mobile phone device is a trusted device according to the first identification information (L iujiang' Iphone) carried in the connection establishment request message, and can establish a pairing-free connection with the trusted device.

At this time, when the wireless router determines that the second mobile phone device is a trusted terminal device, the wireless router displays the name WirelessNet of the wireless network to which the second mobile phone device needs to be connected on the connectable network module of the setting interface of the wireless network, as shown in fig. 10, so as to indicate to the user that the wireless network is a pairing-free connection network, that is, the user can successfully access the network without inputting a user name and a password, thereby improving user experience. And establish pairing-free connection with the second mobile phone device, when the second mobile phone device successfully establishes connection with the wireless router, a connection success mark appears on the left side of the wireless network WirelessNet displayed by the connectable network module, so as to indicate to the user that pairing-free connection with the wireless router is successfully established, and improve user experience.

Optionally, the first identification information is used to indicate the second terminal.

For example, the first terminal and the second terminal are mobile phone devices, and the device to be connected is a wireless router.

By way of example and not limitation. When the wireless router receives first identification information sent by the first terminal (e.g., a first mobile phone device), for example, the first identification information is account information of the first mobile phone device. Since the first identification information is used to indicate the second terminal (e.g., the second handset device). That is, the second terminal is allowed to perform pairing-free connection only when the wireless router receives a connection establishment request message carrying the first identification information (account information of the first mobile phone) sent by the second mobile phone device. Therefore, when another mobile phone device (e.g., a third mobile phone device) sends a connection establishment request message to the wireless router, even if the connection establishment request message sent by the third mobile phone device carries the first identification information, the pairing-free connection cannot be established with the wireless network WirelessNet corresponding to the wireless router.

Optionally, the first terminal sends the first identification information to the second terminal.

By way of example and not limitation. The first terminal (e.g., a first mobile phone device) sends first identification information to the wireless router, for example, the first identification information is randomly generated by the first mobile phone device, and only the first mobile phone device knows the specific content of the first identification information. Therefore, the first mobile phone device needs to send the first identification information to a second terminal (e.g., a second mobile phone device) that establishes a pairing-free connection with the wireless router, in addition to sending the first identification information to the wireless router, so that both the wireless router and the second mobile phone device know the first identification information.

At this time, when the second mobile phone device sends a connection establishment request message carrying the first identification information to the wireless router, and the wireless router receives the connection establishment request message, the connection establishment request passing through the second mobile phone device is determined through the first identification information carried by the connection establishment request message, and pairing-free connection is established with the second mobile phone device.

Optionally, the first terminal sends the first identification information to a cloud space.

Specifically, the first terminal sends the acquired first identification information to a cloud space, and other terminal devices (for example, second terminals) that need to establish pairing-free connection with the device to be connected may acquire the first identification information from the cloud space. Without the first terminal sending the first identification information to the second terminal.

For example, the first terminal (e.g., a first mobile phone device) uploads the first identification information to a cloud space of the first mobile phone device, and shares login information (e.g., login account information and login password information) of the cloud space to a second terminal (e.g., a second mobile phone device). When the second mobile phone device needs to establish pairing-free connection with the device to be connected, the first identification information can be synchronized to the local from the cloud space for storage, and a connection establishment request message carrying the first identification information is sent to the device to be connected.

For example, the first terminal (e.g., a first mobile phone device) sends the acquired first identification information to a cloud space, and the second terminal (e.g., a second mobile phone device) and the first mobile phone device share login information of the cloud space. At this time, the first mobile phone device does not need to send the first identification information to the second mobile phone device, and the second mobile phone device may directly synchronize the first identification information from the cloud space to the local for storage, and send a connection establishment request message carrying the first identification information to the device to be connected.

In the above, step S340 to step S380 are described by taking the first terminal and the second terminal as mobile phone devices, and taking the to-be-connected device as a wireless router as an example.

Next, the steps S340 to S380 will be described by taking the first terminal and the second terminal as mobile phone devices, and taking the device to be connected as a bluetooth device as an example.

After one member in a family establishes connection with a Bluetooth device (e.g., Bluetooth sound) through a first terminal (e.g., a first mobile phone device), the first mobile phone device acquires first identification information. For example, the first identification information is information based on system configuration, that is, all mobile phone devices in a family know the first identification information.

The first mobile phone device sends the first identification information to the bluetooth device, so that when receiving a connection establishment request message carrying the first identification information and sent by other mobile phone devices (e.g., a second mobile phone device) in a family for the first time, the bluetooth device establishes a connection with the second mobile phone device for the first time. The bluetooth device determines that the second mobile phone device is an authenticated device, i.e. a trusted mobile phone device, according to the first identification information carried in the connection establishment request message. At this time, the bluetooth device may allow the second handset device to establish a pairing-free connection, that is, the second handset device may establish a connection with the bluetooth sound without the user inputting a user name and a password.

At this time, in the above case, when another member (hereinafter, referred to as "second user") among the family members needs to make an initial connection with the bluetooth sound through a second terminal (for example, a second mobile phone device), the second user first turns on a switch of the bluetooth sound to enter an operating mode, and enters a bluetooth setting interface of the mobile phone and turns on a bluetooth function of the mobile phone.

At this time, the name of the bluetooth device in the active mode around the first mobile phone device corresponding to the first user is displayed in the available device module of the bluetooth setup interface, as shown in fig. 11. For the bluetooth sound "YOYO" that has already established a connection with the first mobile phone device, when the second mobile phone device clicks the bluetooth sound "YOYO" in the name of the bluetooth device displayed by the available device module, the bluetooth sound will receive a connection establishment request message carrying first identification information sent by the second mobile phone device, and the bluetooth device determines that the second mobile phone device is a trusted device according to the first identification information carried in the connection establishment request message, and may establish a pairing-free connection with the trusted device.

At this moment, when the bluetooth device determines that the second mobile phone device is a trusted terminal device, the bluetooth device displays the name YOYO of the bluetooth sound device to be connected with the second mobile phone device on the connectable device module of the setting interface of the wireless network, so as to indicate the bluetooth device as a pairing-free connection device to the user, that is, the user can successfully establish connection with the bluetooth sound device without inputting a pairing password, thereby improving user experience. And establish pairing-free connection with the second mobile phone device, when the second mobile phone device successfully establishes connection with the bluetooth device, a connection success mark appears on the left side of the name YOYO of the bluetooth sound of the connectable device module, so as to indicate to the user that pairing-free connection with the bluetooth device has been successfully established, and improve user experience.

Alternatively, the device name displayed by the connectable device module or the device name displayed by the connectable network module may be labeled, and the label is used to indicate whether the device or the network can be connected currently. Since it is possible that some previously connected devices or networks are not currently within the connectable range, labeling the device name displayed by the connectable device module or the device name displayed by the connectable network module makes the user clear of the currently connectable devices, improving the user experience.

Optionally, for some previously connected devices, if the previously connected devices are not currently within the connectable range, the user may temporarily delete the terminal device from the device name displayed by the connectable device module or the device name displayed by the connectable network module, so that the user may conveniently select the terminal device to be connected, thereby avoiding the situation that the connection cannot be successfully performed after clicking, and improving the user experience.

It should be understood that the above examples are illustrative only, and are not intended to limit the present application in any way.

Therefore, according to the method for establishing connection, the first terminal firstly completes authentication with the device to be connected and sends the first identification information to the device to be connected, so that after the device to be connected receives the connection establishment request message which is sent by the second terminal and carries the first identification information, the first terminal is determined to be the trusty device according to the first identification information, and pairing-free connection is established with the first terminal, namely the second terminal can successfully establish connection with the device to be connected without inputting a user name and a password by a user, and user experience is improved.
