After the ad hoc network is constructed, each terminal device in the ad hoc network needs to send out BLE broadcast, so as to perform online state maintenance (i.e., keep alive) between the terminal devices. After the ad hoc network is constructed, the first terminal device transmits a first broadcast. Wherein the first broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the first broadcast is a BLE broadcast. Then, after the first terminal device issues the first broadcast (the first broadcast that is not the first time), the first terminal device waits for the second period of time; the second period of time is, for example, 10 seconds.

The first terminal device waits for the second time period, and the first terminal device determines a preset time period before the last moment in the second time period as a first time period. The first terminal device detects whether a second broadcast of the second terminal device is received within a first time period. Wherein the second broadcast is a broadcast based on the bluetooth low energy protocol, i.e., the second broadcast is a BLE broadcast; and, the second broadcast is transmitted in response to a broadcast based on the bluetooth low energy protocol transmitted by a central node in the ad hoc network.

If the first terminal device determines that the second broadcast of the second terminal device is received within the first time period, the first terminal device determines not to kick off the line.

If the first terminal device determines that the second broadcast of the second terminal device is not received within the first duration, the first terminal device needs to establish a connection based on a classical Bluetooth (BR) protocol with the second terminal device (the second terminal device is a device that does not receive the second broadcast sent by the second terminal device), that is, establish a BR connection.

S402, if the first terminal equipment determines that the connection based on the classical Bluetooth protocol is successful, determining a time difference between a first moment and a second moment; the first time is a time after an initial time when the connection based on the classical Bluetooth protocol is established, and the second time is a time when the connection based on the classical Bluetooth protocol is successful.

The first terminal device, after determining that the connection with the second terminal device based on the classical bluetooth protocol was successful, determines the time instant at which the connection based on the classical bluetooth protocol was successful as the second time instant t3. The second terminal equipment records the initial time when the connection based on the classical Bluetooth protocol is established in advance, and the second terminal equipment determines one time after the initial time as the first time; for example, the second terminal device determines a time 8 seconds after the initial time as the first time t4.

The first terminal device calculates a time difference between the first time and the second time, and obtains a time difference w=t4-t 3.

S403, if the first terminal equipment determines that the time difference meets the preset condition, determining to continuously maintain a pre-stored equipment list; the pre-stored device list comprises devices belonging to the same ad hoc network with the first terminal device.

The first terminal device determines whether the time difference W meets a preset condition. For example, the first terminal device determines whether the time difference W is less than or equal to a first preset threshold.

If the first terminal device determines that the time difference W meets the preset condition, the second terminal device is determined to be in the near field, the second terminal device is not off line, and the first terminal device continues to maintain the device list of the first terminal device. The device list of the first terminal device includes devices belonging to the same ad hoc network as the first terminal device.

If the first terminal device determines that the time difference W does not meet the preset condition, the second terminal device is determined not to be in the near field, and the second terminal device is determined to be off-line. At this time, the first terminal device deletes the second terminal device from the device list of the first terminal device; and determining to delete the second terminal device in the first interface. And thus the second terminal device which is offline is not displayed in the first interface.

In this embodiment, if it is determined that after the first broadcast is sent, the second broadcast of the second terminal device is not received within the first time period, a connection based on a classical bluetooth protocol is established between the second terminal device and the second terminal device; if the connection based on the classical Bluetooth protocol is successful, determining the time difference between the first moment and the second moment; the first time is the time after the initial time when the connection based on the classical Bluetooth protocol is established, and the second time is the time when the connection based on the classical Bluetooth protocol is successful; if the time difference meets the preset condition, determining that the second terminal equipment is in the near field, and determining to continuously maintain the pre-stored equipment list without taking the second terminal equipment off line. Therefore, the BR connection is successful, the opposite terminal equipment is determined to be in the near field, and the opposite terminal equipment is not taken off line. Then after the BR connection is successful, calculating the establishment and the success time of the BR connection to obtain a time difference; based on the time difference, it is finally determined whether the opposite device is kicked off. Therefore, the equipment is prevented from being misplaced, the connection reliability between the equipment in the ad hoc network in the super terminal scene is improved, and the reliability of the ad hoc network is improved; the normal operation of the service between the devices in the ad hoc network is ensured.

Fig. 5 is a signaling diagram two of a device processing method based on ad hoc network according to an embodiment of the present application. As shown in fig. 5, the method may include:

s501a, the first terminal equipment responds to an opening instruction and sends out a third broadcast; the starting instruction characterizes the function of starting the super terminal of the first terminal equipment; the third broadcast is a broadcast based on the bluetooth low energy protocol.

S501b, the first terminal equipment receives a fourth broadcast sent by the second terminal equipment; wherein the fourth broadcast is a broadcast based on the bluetooth low energy protocol.

The present embodiment relates to an exemplary terminal device in an ad hoc network, and it is necessary to form an ad hoc network from a plurality of terminal devices. In addition, each terminal device in the ad hoc network has a super terminal function; thus, the user can use the service of the super terminal, such as super connection, super notification, super call, super mouse and the like, between the terminal devices in the ad hoc network.

First, an ad hoc network needs to be composed of a plurality of terminal devices.

The method comprises the steps that a first terminal device obtains an opening instruction, wherein the opening instruction characterizes the function of a super terminal of the first terminal device.

In one example, the first terminal device is a personal computer, and a manager application is installed in the first terminal device, and is used for managing the application in the first terminal device; after the first terminal equipment is started, a manager application in the first terminal equipment is automatically started, and the first terminal equipment can log in an account number of the manager application; the first terminal equipment automatically turns on a switch of the super terminal; then, the first terminal device automatically generates an opening instruction.

In another example, the first terminal device is a personal computer, and a manager application is installed in the first terminal device, where the manager application is used for managing the application in the first terminal device; when a manager application in the first terminal equipment is started, the first terminal equipment can log in an account of the manager application, and the first terminal equipment automatically opens a switch of a super terminal; then, the first terminal device automatically generates an opening instruction.

In another example, the first terminal device is a mobile phone or a tablet computer, and after the first terminal device is started, the first terminal device automatically generates a starting instruction.

Then, the first terminal device issues a third broadcast based on the turn-on instruction. The third broadcast is a broadcast based on a bluetooth low energy (Bluetooth Low Energy, BLE) protocol; that is, the third broadcast is a BLE broadcast. So that the other terminal device can receive the third broadcast of the first terminal device.

And, the period in which the first terminal device transmits the third broadcast is 30 seconds, that is, the third broadcast is transmitted once every 30 seconds; thereby facilitating the second terminal device to receive the third broadcast sent by the first terminal device. To complete the subsequent device authentication process.

For the second terminal device, the second terminal device may also generate its own turn-on command. The process of generating the opening command by the second terminal device may refer to the process of generating the opening command by the first terminal device.

Then, each of the at least one second terminal device issues a fourth broadcast based on the turn-on instruction of the second terminal device. The fourth broadcast is a broadcast based on a low-power consumption Bluetooth protocol; that is, the fourth broadcast is a BLE broadcast. So that the first terminal device can receive the fourth broadcast of each second terminal device.

And, for each second terminal device, the period in which the second terminal device transmits the fourth broadcast is 30 seconds, that is, the fourth broadcast is transmitted once every 30 seconds; thereby facilitating the first terminal device to receive the fourth broadcast sent by the second terminal device. To complete the subsequent device authentication process.

In the scheme, each terminal device in the ad hoc network needs to use the function of the super terminal; the function of the super terminal requires that the terminal equipment starts the Bluetooth function and the wireless local area network (wifi) function. Thus, after the first terminal device generates the start instruction, the first terminal device needs to determine whether to start the bluetooth function and the wireless local area network function; after the second terminal device generates the turn-on instruction, the second terminal device needs to determine whether to turn on the bluetooth function and the wireless local area network function.

In one example, after "responding to the on instruction" in step S501a, the following procedure is further included:

if the Bluetooth function of the first terminal equipment is not started, generating and displaying first prompt information; the first prompt information characterizes whether a user starts a Bluetooth function or not; responding to a first confirmation instruction of a user, and starting a Bluetooth function of the first terminal equipment; the first confirmation instruction is used for indicating to start the Bluetooth function of the first terminal device.

Illustratively, after the first terminal device generates the turn-on instruction, the first terminal device determines whether the first terminal device has turned on the bluetooth function.

If the first terminal equipment determines that the first terminal equipment does not start the Bluetooth function, the first terminal equipment generates and displays first prompt information so as to prompt a user whether to start the Bluetooth function. The user interacts with the first terminal equipment, and the user determines to start the Bluetooth function of the first terminal equipment; the first terminal equipment receives the first confirmation instruction of the user, and then the first terminal equipment starts the Bluetooth function of the first terminal equipment based on the first confirmation instruction.

Or, the first terminal equipment pre-stores first authorization information, wherein the first authorization information comprises scene information capable of automatically starting the Bluetooth function of the first terminal equipment; the scene information characterizes the currently running function of the first terminal device. If the first terminal equipment determines that the Bluetooth function of the first terminal equipment is not started, the first terminal equipment determines that the Bluetooth function of the first terminal equipment can be started automatically according to the first authorization information, and the first terminal equipment starts the Bluetooth function of the first terminal equipment.

And after the first terminal equipment generates the starting instruction, the first terminal equipment judges whether the first terminal equipment starts the wireless local area network function or not.

If the first terminal equipment determines that the first terminal equipment does not start the wireless local area network function, the first terminal equipment generates and displays second prompt information so as to prompt a user whether to start the wireless local area network function. The user interacts with the first terminal equipment, and the user determines to start the wireless local area network function of the first terminal equipment; the first terminal equipment receives the second confirmation instruction of the user, and then the first terminal equipment starts the wireless local area network function of the first terminal equipment based on the second confirmation instruction.

Or, the first terminal equipment pre-stores second authorization information, wherein the second authorization information comprises scene information capable of automatically starting the wireless local area network function of the first terminal equipment; the scene information characterizes the currently running function of the first terminal device. If the first terminal equipment determines that the wireless local area network function of the first terminal equipment is not started, the first terminal equipment determines that the wireless local area network function of the first terminal equipment can be started automatically according to the second authorization information, and the first terminal equipment starts the wireless local area network function of the first terminal equipment.

Then, after determining that the bluetooth function and the wireless local area network function of the first terminal device are turned on, the first terminal device transmits a third broadcast, which is a BLE broadcast.

For each second terminal device, after the second terminal device generates the start instruction, the second terminal device judges whether the second terminal device starts the Bluetooth function.

If the second terminal equipment determines that the second terminal equipment does not start the Bluetooth function, the second terminal equipment generates and displays third prompt information so as to prompt a user whether to start the Bluetooth function. The user interacts with the second terminal equipment, and the user determines to start the Bluetooth function of the second terminal equipment; and the second terminal equipment receives the third confirmation instruction of the user, and then starts the Bluetooth function of the second terminal equipment based on the third confirmation instruction.

Or, the second terminal equipment is pre-stored with third authorization information, wherein the third authorization information comprises scene information capable of automatically starting the Bluetooth function of the second terminal equipment; the scene information characterizes the currently running function of the second terminal device. If the second terminal equipment determines that the Bluetooth function of the second terminal equipment is not started, the second terminal equipment determines that the Bluetooth function of the second terminal equipment can be started automatically according to the third authorization information, and the second terminal equipment starts the Bluetooth function of the second terminal equipment.

And after the second terminal equipment generates the starting instruction, the second terminal equipment judges whether the second terminal equipment starts the wireless local area network function or not.

If the second terminal equipment determines that the second terminal equipment does not start the wireless local area network function, the second terminal equipment generates and displays fourth prompt information so as to prompt a user whether to start the wireless local area network function. The user interacts with the second terminal equipment, and the user determines to start the wireless local area network function of the second terminal equipment; and the second terminal equipment receives the fourth confirmation instruction of the user, and then starts the wireless local area network function of the second terminal equipment based on the fourth confirmation instruction.

Or, the second terminal equipment pre-stores fourth authorization information, wherein the fourth authorization information comprises scene information capable of automatically starting the wireless local area network function of the second terminal equipment; the scene information characterizes the currently running function of the second terminal device. If the second terminal equipment determines that the wireless local area network function of the second terminal equipment is not started, the second terminal equipment determines that the wireless local area network function of the second terminal equipment can be started automatically according to the fourth authorization information, and the second terminal equipment starts the wireless local area network function of the second terminal equipment.

Then, after determining that the bluetooth function and the wireless local area network function of the second terminal device are turned on, the second terminal device transmits a fourth broadcast, which is a BLE broadcast.

S502, performing equipment authentication processing between the first terminal equipment and the second terminal equipment.

In one example, step S502 includes:

the first step of step S502, the first terminal device establishes a bare channel based on the fourth broadcast.

The second step of step S502, the first terminal device sends the first encryption information to the second terminal device through the bare channel; receiving second encryption information sent by a second terminal device through the bare channel; the first encryption information is encrypted device information of the first terminal device, and the second encryption information is encrypted device information of the second terminal device.

And step S502, the first terminal equipment establishes an encryption channel according to the first encryption information and the second encryption information.

A fourth step of step S502, in which the first terminal device sends a first handshake packet to the second terminal device through an encryption channel; and receiving a second handshake packet sent by the second terminal equipment through the encryption channel to finish equipment authentication.

For example, after the first terminal device transmits the third broadcast, the second terminal device may receive the third broadcast of the first terminal device; after the second terminal device transmits the fourth broadcast, the first terminal device may receive the fourth broadcast of the second terminal device. After the first terminal device can receive the fourth broadcast of the second terminal device and the second terminal device can receive the third broadcast of the first terminal device, device authentication processing is performed between the first terminal device and the second terminal device, and then the self-organizing network is built for preparation.

In one example, after the first terminal device may receive the fourth broadcast of the second terminal device and the second terminal device may receive the third broadcast of the first terminal device, a bare channel is established between the first terminal device and the second terminal device, i.e., the first terminal device establishes a bare channel and the second terminal device establishes a bare channel.

Then, the first terminal device encrypts the device information of the first terminal device to obtain encrypted device information of the first terminal device, that is, obtain first encrypted information. Wherein the device information of the first terminal device includes a device name, a device unique identification, a device type, a device address, and the like. The first terminal device sends the first encrypted information to the second terminal device through the bare channel.

And the second terminal device encrypts the device information of the second terminal device to obtain encrypted device information of the second terminal device, that is, obtain second encrypted information. Wherein the device information of the second terminal device includes a device name, a device unique identification, a device type, a device address, and the like. And the second terminal equipment sends the second encrypted information to the first terminal equipment through the bare channel.

Thus, the first terminal device and the second terminal device interact with each other's device information. The first terminal equipment establishes an encryption channel based on the first encryption information and the second encryption information; the first terminal equipment establishes an encryption channel based on the first encryption information and the second encryption information; the two encryption channels are the same channel. That is, an encryption channel is established between the first terminal device and the second terminal device based on the first encryption information and the second encryption information.

Then, the first terminal equipment sends a first handshake packet to the second terminal equipment through an encryption channel; and the second terminal device sends a second handshake packet to the first terminal device through the encrypted channel. Thus, the process of the device authentication processing is completed between the first terminal device and the second terminal device.

S503, the first terminal device displays the device information of the second terminal device in the first interface; the first interface is used for displaying the devices in the pre-stored device list.

After the device authentication process is completed between the first terminal device and the second terminal device, the first terminal device reports the device information of the second device to the first interface of the manager application of the first terminal device for display through a Profile module of the code layer. Thus, the first terminal device displays information of other terminal devices passing through the device authentication on the first interface. At this time, the device information of the second device is reported to the manager, including the device name, the unique identifier of the device, the device type, and the like; but does not include a device address.

And if the ad hoc network is established in the subsequent process, each terminal device needs to store a device list, and the device list of each terminal device comprises devices belonging to the same ad hoc network with the terminal device. The device list includes device information of devices belonging to the same ad hoc network as the terminal device. Device information in the device list, including but not limited to: device name, device unique identification, device type, device address.

In this step, after the device authentication process is completed between the first terminal device and the second terminal device, since the process of the device authentication process is to prepare for the subsequent construction of the ad hoc network, the first terminal device can generate the device list of the first terminal device at this time. The first terminal equipment provides a first interface which is used for displaying equipment information of equipment in a pre-stored equipment list; wherein, for security and privacy reasons, the device address is not included in the device information displayed by the first interface.

S504, the first terminal equipment determines the equipment score of the first terminal equipment. Wherein the device score of the first terminal device is related to the operational status of the first terminal device.

In one example, step S504 includes: acquiring state information of a first terminal device; the state information of the first terminal equipment comprises at least one state parameter, and the state parameter of the first terminal equipment represents the current state of the first terminal equipment. And determining the equipment score of the first terminal equipment according to the state parameter in the state information of the first terminal equipment and the preset weight corresponding to the state parameter.

In one example, the status information of the first terminal device includes one or more of the following status parameters: charging parameters, screen locking parameters, first network discovery parameters, second network discovery parameters and battery power parameters.

The charging parameters represent whether the terminal equipment is charged, the screen locking parameters represent whether the terminal equipment is screen locked, the first network discovery parameters represent whether the terminal equipment supports CoAp discovery, the second network discovery parameters represent whether the terminal equipment supports low-power Bluetooth discovery, and the battery power parameters represent whether the current battery residual power of the terminal equipment is larger than or equal to a second preset threshold value.

In one example, the device Score of the first terminal device is score=ischaring 16+isUnlock 8+iscoappsup 4+isceappsup 2+highpacket 1.

The isCharing is a charging parameter of the first terminal device, the isUnlock is a screen locking parameter of the first terminal device, the iscoappsup is a first network discovery parameter of the first terminal device, the isceappsup is a second network discovery parameter of the first terminal device, and the highBattery is a battery power parameter of the first terminal device.

For example, after the device authentication process is completed between the first terminal device and each second terminal device, the center node and the edge node need to be selected from the first terminal device and each second terminal device, and thus the ad hoc network needs to be built.

For the first terminal equipment, the first terminal equipment determines the equipment score of the first terminal equipment according to the running state of the first terminal equipment. The operating state of the first terminal device includes, but is not limited to: whether the terminal device is charged, whether the terminal device is screen locked, whether the terminal device supports CoAp (The Constrained Application Protocol) discovery, whether the terminal device supports bluetooth low energy discovery, the current battery level remaining of the terminal device, and so on.

In one example, a first terminal device obtains state information of the first terminal device; the state information of the first terminal device includes at least one state parameter. Preset weights corresponding to the state parameters are preset for each state parameter in advance. The first terminal equipment calculates the equipment score of the first terminal equipment according to each state parameter of the first terminal equipment and the preset weight corresponding to each state parameter.

The first terminal device obtains a charging parameter of the first terminal device, wherein the charging parameter characterizes whether the terminal device is charged (i.e. whether charging is being performed or whether charging is completed). And the charging parameters have preset weights.

The method comprises the steps that a first terminal device obtains a screen locking parameter of the first terminal device, wherein the screen locking parameter represents whether the terminal device locks a screen or not. And the screen locking parameters have preset weights. Wherein, the value of the preset weight of the state parameter is strongly related to the service; the terminal device is being charged or the terminal device has completed charging, the terminal device has strong capability, and the terminal device can do more tasks, so that a higher weight value needs to be set for the charging parameter. Therefore, the preset weight corresponding to the charging parameter is greater than the preset weight corresponding to the screen locking parameter.

The first terminal device obtains a first network discovery parameter of the first terminal device, wherein the first network discovery parameter characterizes whether the terminal device supports CoAp discovery. And if the terminal equipment is not locked, the terminal equipment has strong capability and can do more tasks, so that the preset weight corresponding to the screen locking parameter is greater than the preset weight corresponding to the first network discovery parameter.

The first terminal device obtains a second network discovery parameter of the first terminal device, wherein the second network discovery parameter characterizes whether the terminal device supports bluetooth low energy discovery. Because the scheme is based on the scene of the ad hoc network, the ad hoc network comprises a plurality of terminal devices, and signaling and information need to be transmitted among the plurality of terminal devices, so that the preset weight corresponding to the first network discovery parameter is greater than the preset weight corresponding to the second network discovery parameter.

The first terminal equipment acquires a battery power parameter of the first terminal equipment, wherein the battery power parameter characterizes whether the current battery residual power of the terminal equipment is larger than or equal to a second preset threshold value. The scheme is that a protocol based on low-power consumption Bluetooth is required to send out broadcasting, so that the preset weight corresponding to the second network discovery parameter is greater than the preset weight corresponding to the battery power parameter.

For example, if the first terminal device is charged (is charging or has completed charging), the charging parameter of the first terminal device has a value of 1; if the first terminal device is not charged (is not charged, or is not charged), the value of the charging parameter of the first terminal device is 0. The preset weight corresponding to the charging parameter of the first terminal equipment is 16.

If the screen of the first terminal equipment is unlocked, the value of the screen locking parameter of the first terminal equipment is 1; and if the screen of the first terminal equipment is locked, the value of the screen locking parameter of the first terminal equipment is 0. The preset weight corresponding to the screen locking parameter of the first terminal equipment is 8.

If the first terminal equipment supports the Coap discovery, the value of the first network discovery parameter of the first terminal equipment is 1; if the first terminal device supports the Coap discovery, the value of the first network discovery parameter of the first terminal device is 0. The preset weight corresponding to the first network discovery parameter of the first terminal equipment is set to be 4.

If the first terminal equipment supports BLE discovery, the value of the second network discovery parameter of the first terminal equipment is 1; if the first terminal device does not support BLE discovery, the value of the second network discovery parameter of the first terminal device is 0. The preset weight corresponding to the second network discovery parameter of the first terminal equipment is 2.

If the current battery remaining capacity of the first terminal device is greater than or equal to a second preset threshold, for example, the second preset threshold is 50%, the value of the battery capacity parameter of the first terminal device is 1; if the current battery remaining capacity of the first terminal device is smaller than a second preset threshold, for example, the second preset threshold is 50%, the value of the battery capacity parameter of the first terminal device is 0. The preset weight corresponding to the battery power parameter of the first terminal equipment is 1.

Then, the first terminal device obtains a charging parameter isCharing of the first terminal device, a screen locking parameter isUnlock of the first terminal device, an iscoapplort of a first network discovery parameter of the first terminal device, an iscble support of a second network discovery parameter of the first terminal device, and a highBattery of a battery power parameter of the first terminal device according to the above process. And, the first terminal device has previously acquired a preset weight corresponding to each state parameter. Then, the first terminal device calculates a device Score of the first terminal device.

For example, the first terminal device calculates a device Score score=ischaring 16+isconnock 8+iscoappsup 4+iscblesup 2+highbattery 1 of the first terminal device.

The first terminal device sends the device score of the first terminal device to each second terminal device through BLE broadcasting.

S505, the first terminal equipment receives the equipment score of the second terminal equipment sent by the second terminal equipment; the device score of the second terminal device is related to the operational status of the second terminal device.

The first terminal device also needs to know the device score of the second terminal device, for example. The device score of the second terminal device is calculated by the second terminal device.

And for each second terminal device, the second terminal device determines the device score of the second terminal device according to the running state of the second terminal device. The operating state of the second terminal device includes, but is not limited to: whether the terminal device is charged, whether the terminal device is screen locked, whether the terminal device supports CoAp (The Constrained Application Protocol) discovery, whether the terminal device supports bluetooth low energy discovery, the current battery level remaining of the terminal device, and so on.

In one example, the second terminal device obtains state information of the second terminal device; the state information of the second terminal device includes at least one state parameter. Preset weights corresponding to the state parameters are preset for each state parameter in advance. And the second terminal equipment calculates the equipment score of the second terminal equipment according to each state parameter of the second terminal equipment and the preset weight corresponding to each state parameter.

The second terminal device obtains a charging parameter of the second terminal device, wherein the charging parameter characterizes whether the terminal device is charged (i.e. whether charging is being performed or whether charging is completed). And the charging parameters have preset weights.

The second terminal equipment acquires a screen locking parameter of the second terminal equipment, wherein the screen locking parameter characterizes whether the terminal equipment locks a screen or not. And the screen locking parameters have preset weights. Wherein, the value of the preset weight of the state parameter is strongly related to the service; the terminal device is being charged or the terminal device has completed charging, the terminal device has strong capability, and the terminal device can do more tasks, so that a higher weight value needs to be set for the charging parameter. Therefore, the preset weight corresponding to the charging parameter is greater than the preset weight corresponding to the screen locking parameter.

The second terminal device obtains a first network discovery parameter of the second terminal device, wherein the first network discovery parameter characterizes whether the terminal device supports CoAp discovery. The terminal equipment is unlocked, the terminal equipment has strong capability and can do more tasks, so that the preset weight corresponding to the screen locking parameter is larger than the preset weight corresponding to the first network discovery parameter,

the second terminal device obtains a second network discovery parameter of the second terminal device, wherein the second network discovery parameter characterizes whether the terminal device supports bluetooth low energy discovery. Because the scheme is based on the scene of the ad hoc network, the ad hoc network comprises a plurality of terminal devices, and signaling and information need to be transmitted among the plurality of terminal devices, so that the preset weight corresponding to the first network discovery parameter is greater than the preset weight corresponding to the second network discovery parameter.

The second terminal equipment acquires battery power parameters of the second terminal equipment, wherein the battery power parameters represent whether the current battery residual power of the terminal equipment is larger than or equal to a second preset threshold value. The scheme is that a protocol based on low-power consumption Bluetooth is required to send out broadcasting, so that the preset weight corresponding to the second network discovery parameter is greater than the preset weight corresponding to the battery power parameter.

For example, if the second terminal device is charged (is charging or has completed charging), the charging parameter of the second terminal device has a value of 1; if the second terminal device is not charged (is not charged, or is not charged), the value of the charging parameter of the second terminal device is 0. The preset weight corresponding to the charging parameter of the second terminal device is 16.

If the screen of the second terminal equipment is unlocked, the value of the screen locking parameter of the second terminal equipment is 1; and if the screen of the second terminal equipment is locked, the value of the screen locking parameter of the second terminal equipment is 0. The preset weight corresponding to the screen locking parameter of the second terminal equipment is 8.

If the second terminal equipment supports the Coap discovery, the value of the first network discovery parameter of the second terminal equipment is 1; if the second terminal device supports the Coap discovery, the value of the first network discovery parameter of the second terminal device is 0. The preset weight corresponding to the first network discovery parameter of the second terminal equipment is set to be 4.

If the second terminal equipment supports BLE discovery, the value of the second network discovery parameter of the second terminal equipment is 1; and if the second terminal equipment does not support BLE discovery, the value of the second network discovery parameter of the second terminal equipment is 0. The preset weight corresponding to the second network discovery parameter of the second terminal equipment is 2.

If the current battery remaining capacity of the second terminal equipment is greater than or equal to a second preset threshold, for example, the second preset threshold is 50%, the value of the battery capacity parameter of the second terminal equipment is 1; if the current battery remaining capacity of the second terminal device is smaller than the second preset threshold, for example, the second preset threshold is 50%, the value of the battery capacity parameter of the second terminal device is 0. The preset weight corresponding to the battery power parameter of the second terminal equipment is 1.

And then, the second terminal equipment obtains a charging parameter isCharing1 of the second terminal equipment, a screen locking parameter isUnlock1 of the second terminal equipment, an iscoappsupport 1 of a first network discovery parameter of the second terminal equipment, an iscblesupport 1 of a second network discovery parameter of the second terminal equipment and a highBattery1 of a battery power parameter of the second terminal equipment according to the above process. And, the second terminal device has previously acquired a preset weight corresponding to each state parameter. Then, the second terminal device calculates a device Score1 of the second terminal device.

For example, the second terminal device calculates a device Score of the second terminal device of Score 1=ischaring 1 x 16+isconnock1 x 8+iscoappsuppalt1 x 4+iscblesupport1 x 2+highbattery1 x 1.

For each second terminal device, the second terminal device transmits the device score of the second terminal device to the first terminal device through BLE broadcast.

Thus, the first terminal device obtains the device score of the first terminal device, and the device score of each of the second terminal devices.

And for each second terminal device, the first terminal device sends the score of the first terminal device to each second terminal device through BLE broadcasting; each second terminal device has calculated its own device score. Thus, for each second terminal device, the second terminal device also has a device score for the first terminal device, a device score for each of the second terminal devices.

S506, the first terminal equipment determines a center node and an edge node in the ad hoc network according to the equipment score of the first terminal equipment and the equipment score of the second terminal equipment.

In one example, step S506 includes: the first terminal equipment determines that the equipment score belongs to the terminal equipment with a preset score range and is a central node of the ad hoc network; the rest of the terminal equipment is an edge node of the ad hoc network.

The first terminal device is illustratively pre-selected to store a list of devices that includes devices belonging to the same ad hoc network as the first terminal device. The device list includes device information of devices belonging to the same ad hoc network as the terminal device. But at this time, since the ad hoc network has not been built; therefore, included in the device list at this time is a device adjacent to the first terminal device.

The first terminal equipment writes the equipment score of the first terminal equipment and the equipment score of each second terminal equipment in the terminal equipment into an equipment list.

The first terminal equipment obtains the equipment score of the first terminal equipment and the equipment score of each second terminal equipment in each terminal equipment; then, the first terminal device obtains the device score of the first terminal device and the device score of each second terminal device in each terminal device, and selects a center node and an edge node in the ad hoc network.

In one example, the first terminal device has acquired a device score for the first terminal device, a device score for each second terminal device in the respective terminal devices; the first terminal equipment compares the scores of the equipment, determines that the score of the equipment belongs to the terminal equipment with a preset score range and is a central node of the ad hoc network; the first terminal equipment determines that the rest of the terminal equipment is an edge node of the ad hoc network.

For example, the first terminal device has acquired a device score for the first terminal device, a device score for each second terminal device; comparing the scores of the devices by the first terminal device, and determining the terminal device with the largest score as a central node of the ad hoc network; the first terminal equipment determines that the rest of the terminal equipment is an edge node of the ad hoc network.

For another example, the first terminal device has acquired a device score for the first terminal device, a device score for each second terminal device; the first terminal equipment compares the equipment scores, determines that the equipment scores belong to the terminal equipment within a preset value range and is a central node of the ad hoc network; the first terminal equipment determines that the rest of the terminal equipment is an edge node of the ad hoc network.

The second terminal equipment obtains the equipment score of the first terminal equipment and the equipment score of each second terminal equipment in the terminal equipment; the second terminal equipment compares the scores of the equipment, determines that the score of the equipment belongs to the terminal equipment with a preset score range and is a central node of the ad hoc network; the second terminal equipment determines the rest terminal equipment as the edge node of the ad hoc network.

For example, the second terminal device has acquired the device score of the first terminal device, the device score of each second terminal device; comparing the scores of the devices by the second terminal equipment, and determining the terminal equipment with the largest score as a central node of the ad hoc network; the second terminal equipment determines the rest terminal equipment as the edge node of the ad hoc network.

For another example, the second terminal device has acquired the device score of the first terminal device, the device score of each second terminal device; the second terminal equipment compares the equipment scores, determines that the equipment scores belong to the terminal equipment within a preset value range and is a central node of the ad hoc network; the second terminal equipment determines the rest terminal equipment as the edge node of the ad hoc network.

The device score of each terminal device is acquired by the first terminal device, and the device score of each terminal device is also acquired by the second terminal device. The first terminal equipment selects a mode of a center node and an edge node according to the equipment scores of the terminal equipment; the second terminal equipment selects a mode of a center node and an edge node according to the equipment scores of the terminal equipment; the selection modes of the two are the same. So the center nodes determined by the first terminal equipment are the same as the center nodes determined by each second terminal equipment; the edge nodes determined by the first terminal device and the edge nodes determined by each second terminal device are identical.

Further, each terminal device maintains a list of devices of all surrounding terminal devices (the list of devices at this time includes a device score); each terminal device performs election. So that all terminal devices know which is the center node and which is the edge node.

Based on the above process, the center node and each edge node are obtained, so that the center node and each edge node of the ad hoc network are determined from the first terminal device and each second terminal device. The obtained ad hoc network comprises a plurality of terminal devices; one of a plurality of terminal devices in the ad hoc network is a central node of the ad hoc network; the rest of the plurality of terminal devices in the ad hoc network are all edge nodes of the ad hoc network.

According to the architecture of fig. 6 and 7, the first terminal device turns on the switch of the super terminal and turns on the bluetooth function and the wireless lan function. The first self-discovery module of the first terminal equipment sends out a third broadcast through the first broadcast module, and the third broadcast is BLE broadcast; wherein the first terminal device transmits the third broadcast once every 30 seconds.

The second terminal device turns on the switch of the super terminal and turns on the Bluetooth function and the wireless local area network function. A second self-discovery module of the second terminal equipment sends out a fourth broadcast through a second broadcast module, wherein the fourth broadcast is BLE broadcast; wherein the second terminal device transmits a fourth broadcast every 30 seconds.

And after the first terminal equipment receives the fourth broadcast and the second terminal equipment receives the third broadcast, a naked channel is established between the first terminal equipment and the second terminal equipment. The first terminal device and the second terminal device exchange encryption information and then establish an encryption channel. And the first terminal equipment and the second terminal equipment are mutually wrapped by handshake to finish the process of equipment authentication processing.

Then, the first terminal device reports the device information of the second terminal device (at this time, the authentication between the second terminal device and the first terminal device is passed) to the first interface through the Profile module of the first terminal device; the first terminal device displays device information of the second terminal device on the first interface. At this time, the device information displayed in the first interface may include a device name, a device unique identifier, a device type, and the like; but does not include a device address.

The first terminal equipment sends the equipment information of the second terminal equipment to a first equipment information updating module in a first discovery module; the first device information updating module of the first terminal device updates a device list in the first terminal device.

And a first equipment information updating module in a first discovery module of the first terminal equipment determines the equipment score of the first terminal equipment according to the running state of the first terminal equipment.

S507, the first terminal equipment waits for a second duration after sending out the first broadcast.

The second terminal equipment is equipment belonging to the same self-organizing network with the first terminal equipment, and the self-organizing network comprises at least one terminal equipment; the first broadcast is a broadcast based on the bluetooth low energy protocol.

Fig. 11 is a signaling diagram illustrating a construction process of an ad hoc network according to an embodiment of the present application, as shown in fig. 11, in step S1101, the first terminal device sends out the third broadcast. Step S1102, the second terminal device sends out the fourth broadcast. Step S1103, the first terminal device performs the above-mentioned device authentication processing procedure. Step S1104, the second terminal device performs the device authentication process.

And then if the first terminal equipment is on line, the first terminal equipment sends out BLE broadcasting, and the second self-discovery module of the second terminal equipment can receive the BLE broadcasting of the first terminal equipment. If the second terminal device is on line, the second terminal device sends out a BLE broadcast, and the first discovery module of the first terminal device can receive the BLE broadcast of the second terminal device.

Then, in step S1105, the first terminal device determines a center node and an edge node in the ad hoc network. And S1106, the second terminal equipment determines a center node and an edge node in the ad hoc network. Thereby constructing an ad hoc network.

After the ad hoc network is constructed, each terminal device in the ad hoc network needs to send out BLE broadcast, so as to perform online state maintenance (i.e., keep alive) between the terminal devices. However, each terminal device in the ad hoc network sends out a BLE broadcast, and due to short-distance power consumption control, there is a case that the BLE function of the terminal device is dormant, or there is a case that the terminal device scans the BLE broadcast of other terminal devices; at this time, if the terminal device does not receive the BLE broadcast of some other terminal device after sending the BLE broadcast, the terminal device will kick off the other terminal device; however, the other terminal devices are not separated from the near field, so that the device is misplaced, and the service processing cannot be normally performed, thereby affecting the user experience.

In one example, after an ad hoc network is built, a first terminal device transmits a first broadcast. Wherein the first broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the first broadcast is a BLE broadcast. Then, the first terminal equipment waits for a second duration; the second period of time is, for example, 10 seconds. Then, after waiting for the second duration, the first terminal device drops the second terminal device if it is determined that the second broadcast of the second terminal device is not received within the first duration; wherein the first duration is for example 21 seconds. The second broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the second broadcast is a BLE broadcast. Thus, the first terminal device deletes the second terminal device in the device list. The first terminal device no longer maintains information of the second terminal device, and the first terminal device no longer performs service communication with the second terminal device.

However, in the above process, there may be a case where the BLE function of the second terminal device is dormant, or there may be a case where the first terminal device scans BLE broadcast not requiring the second terminal device; it is known that the second terminal device is not away from the near field. The first terminal equipment misplaces the second terminal equipment, so that the service processing can not be normally performed.

For example, fig. 12 is a signaling diagram three of an apparatus processing method based on an ad hoc network according to an embodiment of the present application, as shown in fig. 12, a first terminal apparatus is a central node, and each second terminal apparatus is an edge node. Taking the first terminal equipment as a central node, the second terminal equipment A as an edge node and the second terminal equipment B as an edge node as an example for illustration and description.

S1201, after an ad hoc network is constructed, a first terminal device serving as a central node sends out a first broadcast; the first broadcast is a BLE broadcast.

The first terminal equipment serving as a central node in the ad hoc network performs active broadcasting, namely, the first terminal equipment serving as the central node sends out first broadcasting. Wherein the period of the first broadcast is 30 seconds; it is known that the first terminal device as the center node actively transmits the first broadcast once every 30 seconds. The first broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the first broadcast is a BLE broadcast.

S1202, after receiving the first broadcast, the second terminal equipment A serving as an edge node sends out a second broadcast of the second terminal equipment A; the second broadcast is a BLE broadcast.

Wherein the second terminal device a as an edge node in the ad hoc network performs a follow-up broadcast after receiving the first broadcast, i.e. the second terminal device a as an edge node issues a second broadcast after receiving the first broadcast. Wherein the period of the second broadcast is 20 seconds; it is known that the second terminal device a, which is an edge node, actively transmits a second broadcast every 20 seconds after receiving the first broadcast. The second broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the second broadcast is a BLE broadcast.

Thereby performing the keep-alive.

S1203, after receiving the first broadcast, the second terminal device B serving as the edge node sends out a second broadcast of the second terminal device B; the second broadcast is a BLE broadcast.

S1204, the first terminal equipment sends out a first broadcast again; the first broadcast is a BLE broadcast.

Wherein, after receiving the first broadcast again, the second terminal device a sends out the second broadcast of the second terminal device a again; the second broadcast is a BLE broadcast.

After the second terminal device B receives the first broadcast again, the second terminal device B sends out the second broadcast again; the second broadcast is a BLE broadcast.

S1205, the first terminal equipment waits for a second duration.

Wherein the second time period is for example 10 seconds. After the first terminal device does not first issue the first broadcast, steps S1205-S1206 are performed each time the first broadcast is issued.

S1206, after waiting for the second duration, if it is determined that the second broadcast of the second terminal device B is not received within the first duration, the first terminal device drops the second terminal device B.

Wherein the first duration is for example 21 seconds. After waiting for the second time period, the first terminal device determines whether a second broadcast of each second terminal device is received within a first time period preceding a last time of the second time period. And if the first terminal equipment determines that the second broadcast of the second terminal equipment B is not received within the first time period, the second terminal equipment B is disconnected.

For example, the first terminal device detects whether or not a second broadcast of each second terminal device is received within the past 21 seconds after waiting for 10 seconds; if the first terminal device determines that the second broadcast of the second terminal device B is not received within the past 21 seconds after waiting for 10 seconds, the first terminal device kicks off the second terminal device B.

In the process shown in fig. 12, there may be a case where the BLE function of the second terminal device is dormant, or there may be a case where the first terminal device scans BLE broadcast without the second terminal device; it is known that the second terminal device is not away from the near field. The first terminal equipment misplaces the second terminal equipment, so that the service processing can not be normally performed.

For example, fig. 13 is a signaling diagram of a device processing method based on ad hoc network according to an embodiment of the present application, as shown in fig. 13, a first terminal device is an edge node, a certain second terminal device is a center node, and the rest of second terminal devices are all edge nodes. Taking the first terminal equipment as an edge node and the second terminal equipment as an edge node as an example, the description is given by way of example.

S1301, after an ad hoc network is built, the equipment serving as a central node sends out active broadcast; the active broadcast is a BLE broadcast.

The device serving as the central node in the ad hoc network performs active broadcasting, that is, the device serving as the central node sends out active broadcasting. Wherein the period of active broadcasting is 30 seconds; it is known that a device as a central node actively transmits an active broadcast once every 30 seconds. Active broadcast is a broadcast based on the bluetooth low energy protocol, i.e. active broadcast is BLE broadcast.

S1302, after receiving the active broadcast, the first terminal device serving as the edge node sends out a first broadcast of the first terminal device; the first broadcast is a BLE broadcast.

Wherein the first terminal device as an edge node in the ad hoc network performs following broadcast after receiving the active broadcast, i.e. the first terminal device as an edge node sends out the first broadcast after receiving the active broadcast. Wherein the period of the first broadcast is 20 seconds; it is known that the first terminal device as the edge node actively transmits a first broadcast every 20 seconds after receiving the first active broadcast. The first broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the first broadcast is a BLE broadcast.

Thereby performing the keep-alive.

S1303, after receiving the active broadcast, the second terminal device serving as the edge node sends out a second broadcast of the second terminal device; the second broadcast is a BLE broadcast.

Wherein the second terminal device as an edge node in the ad hoc network performs the follow-up broadcast after receiving the active broadcast, i.e. the second terminal device as an edge node sends out the second broadcast after receiving the active broadcast. Wherein the period of the second broadcast is 20 seconds; it is known that the second terminal device, which is an edge node, actively transmits a second broadcast every 20 seconds after receiving the first active broadcast. The second broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the second broadcast is a BLE broadcast.

S1304, the equipment of the central node sends out active broadcast again; the active broadcast is a BLE broadcast.

The method comprises the steps that after the first terminal equipment receives active broadcasting again, the first terminal equipment sends out first broadcasting of the first terminal equipment again; the first broadcast is a BLE broadcast.

The second terminal equipment sends out the second broadcast of the second terminal equipment again after receiving the active broadcast again; the second broadcast is a BLE broadcast.

S1305, the first terminal device waits for a second duration.

Wherein the second time period is for example 10 seconds. After the first terminal device does not first issue the first broadcast, steps S1305 to S1306 are executed each time the first broadcast is issued.

S1306, after waiting for the second duration, the first terminal device drops the second terminal device if it is determined that the second broadcast of the second terminal device is not received within the first duration.

Wherein the first duration is for example 21 seconds. After waiting for the second time period, the first terminal device determines whether a second broadcast of each second terminal device is received within a first time period preceding a last time of the second time period. And if the first terminal equipment determines that the second broadcast of the second terminal equipment is not received within the first duration, the second terminal equipment is disconnected.

For example, the first terminal device detects whether or not a second broadcast of the second terminal device is received within the past 21 seconds after waiting for 10 seconds; if the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21 seconds after waiting for 10 seconds, the first terminal device drops the second terminal device.

In the process shown in fig. 13, there may be a case where the BLE function of the second terminal device is dormant, or there may be a case where the first terminal device scans BLE broadcast without the second terminal device; it is known that the second terminal device is not away from the near field. The first terminal equipment misplaces the second terminal equipment, so that the service processing can not be normally performed.

In the present application, at the time of execution to step S507, after the ad hoc network is constructed, it is required that each terminal device in the ad hoc network transmits BLE broadcast, so as to perform online state maintenance (i.e., keep-alive) between the terminal devices. After the ad hoc network is constructed, the first terminal device transmits a first broadcast. Wherein the first broadcast is a broadcast based on the bluetooth low energy protocol, i.e. the first broadcast is a BLE broadcast. Then, after the first terminal device issues the first broadcast (the first broadcast that is not the first time), the first terminal device waits for the second period of time; the second period of time is, for example, 10 seconds.

And S508, after the second time period, if the first terminal equipment does not receive the second broadcast of the second terminal equipment in the first time period, establishing connection based on a classical Bluetooth protocol with the second terminal equipment.

Wherein the second broadcast is a broadcast based on a bluetooth low energy protocol; the second broadcast is sent in response to a bluetooth low energy protocol based broadcast sent by a central node in the ad hoc network.

The first time includes a period before the transmission time and a period after the transmission time, the transmission time being a time at which the first broadcast is transmitted; the first time period is a preset period before the last time in the second time period.

In one example, the second duration is 10 seconds; the first duration was 21 seconds.

In one example, if the first terminal device is a central node in the ad hoc network, the second broadcast is sent in response to the first broadcast; if the first terminal device is an edge node in the ad hoc network, the second broadcast is sent in response to a bluetooth low energy broadcast by a central node in the ad hoc network.

If the first terminal device is a central node in the ad hoc network, the transmission period of the first broadcast is 30 seconds, and the transmission period of the second broadcast is 20 seconds. If the first terminal device is an edge node in the ad hoc network, the transmission period of the first broadcast is 20 seconds, and the transmission period of the second broadcast is 30 seconds.

In one example, the "establishing a connection with the second terminal device based on the classical bluetooth protocol" in step S508 includes:

acquiring an address of a second terminal device based on a classical Bluetooth protocol; and establishes a physical link with the second terminal device based on the classical bluetooth protocol based address.

If the physical link is established successfully, a success instruction is fetched from the first terminal equipment; wherein the success instruction characterizes a success of the connection with the second terminal device based on the classical bluetooth protocol.

Illustratively, after step S507, the first terminal device waits for a second duration, and the first terminal device determines a preset period of time before a last time in the second duration as a first duration. The first terminal device detects whether a second broadcast of the second terminal device is received within a first time period. Wherein the second broadcast is a broadcast based on the bluetooth low energy protocol, i.e., the second broadcast is a BLE broadcast; and, the second broadcast is transmitted in response to a broadcast based on the bluetooth low energy protocol transmitted by a central node in the ad hoc network.

The time when the first terminal equipment sends out the first broadcast is the sending time; after the transmission time, a second period of time is waited. The first terminal device detects whether a second broadcast of the second terminal device is received within a preset period (i.e., a first period) preceding a last time of the second period. And, the first time period includes a period before the transmission time and a period after the transmission time. For example, the second duration is 10 seconds and the first duration is 21 seconds; after the first terminal device sends out the sending moment of the first broadcast, waiting for 10 seconds, and then detecting whether the first terminal device receives the second broadcast of the second terminal device within the past 21 seconds; as can be seen, the 21 seconds includes a period before the transmission timing and a period after the transmission timing.

Wherein a connection based on the classical bluetooth protocol, i.e. a BR connection, needs to be established between a "first terminal device and a second terminal device, which is a device that does not receive the second broadcast it sent. "procedure is described below.

After the authentication is passed due to the procedure of the previous device authentication process, the first terminal device may acquire the address of the second terminal device based on the classical bluetooth protocol from the interface, i.e. acquire the BR address of the second terminal device. Then, the first terminal device establishes a physical link with the second terminal device according to the BR address of the second terminal device.

And after the physical link is successfully established, performing a callback process. Because the establishment of the physical link is completed between the bottom layer of the first terminal device and the bottom layer of the second terminal device, the first terminal device can call a success instruction from the inside of the first terminal device; wherein the success instruction characterizes the success of the connection between the first terminal device and the second terminal device based on the classical Bluetooth protocol. The second terminal equipment can call a success instruction from the inside of the second terminal equipment; wherein the success instruction characterizes the success of the connection between the first terminal device and the second terminal device based on the classical Bluetooth protocol.

S509, if the first terminal equipment determines that the connection based on the classical Bluetooth protocol is successful, determining a time difference between a first time and a second time; the first time is a time after an initial time when the connection based on the classical Bluetooth protocol is established, and the second time is a time when the connection based on the classical Bluetooth protocol is successful.

S510, if the first terminal equipment determines that the time difference is smaller than or equal to a first preset threshold value, the first terminal equipment determines to continuously maintain a pre-stored equipment list. The pre-stored device list comprises devices belonging to the same ad hoc network with the first terminal device.

The first terminal device determines, for example, whether the time difference W is equal to or less than a first preset threshold. If the first terminal equipment determines that the time difference W is smaller than or equal to the first preset threshold value, the second terminal equipment is determined to be in the near field, the second terminal equipment is not off line, and the first terminal equipment continues to maintain the equipment list of the first terminal equipment.

The device list of the first terminal device includes devices belonging to the same ad hoc network as the first terminal device. The list of devices is presented in the description of the steps above.

S511, if the first terminal equipment determines that the time difference is greater than a first preset threshold, deleting the second terminal equipment from a pre-stored equipment list; and determining to delete the second terminal device in a first interface, wherein the first interface is used for displaying devices in a pre-stored device list.

In one example, the difference between the first time and the initial time is 8 seconds; the first preset threshold is 29 seconds.

For example, if the first terminal device determines that the time difference W is greater than the first preset threshold, it determines that the second terminal device is not in the near field, and determines to kick the second terminal device off line. At this time, the first terminal device deletes the second terminal device from the device list of the first terminal device; and determining to delete the second terminal device in the first interface. And thus the second terminal device which is offline is not displayed in the first interface.

In one example, after step S506, an ad hoc network is obtained, where the ad hoc network includes a plurality of terminal devices. The first terminal equipment is a central node in the ad hoc network, and the second terminal equipment is an edge node in the ad hoc network.

The first terminal device actively transmits a first broadcast, which is a BLE broadcast, every 30 seconds. The second terminal device transmits a following broadcast every 20 seconds after receiving the first broadcast; that is, the second terminal device transmits a second broadcast, which is a BLE broadcast, every 20 seconds after receiving the first broadcast. And the second terminal device may also receive the following broadcast of other edge nodes in the ad hoc network.

Then, the first terminal device waits for 10 seconds after each first broadcast (first broadcast other than the first time), at which time point t2 is reached. The first terminal device then detects whether a following broadcast of each edge node is received within the past 21 seconds, so that the first terminal device detects whether a second broadcast of the second terminal device is received within the past 21 seconds.

In case 1, if the first terminal device determines that the second broadcast of each second terminal device is received, the first terminal device continues to execute the process of sending the first broadcast once every 30 seconds.

And 2, if the first terminal equipment determines that the second broadcast of the second terminal equipment is not received, the second terminal equipment is not started to be off line.

It is possible that the second terminal device does not deliver the second broadcast or that the first terminal device does not receive the second broadcast of the second terminal device due to network reasons. However, if the second terminal device is in the near field and the first terminal device drops off the line, the second terminal device is misplaced, so that the service and the opposite terminal device cannot be used as the service.

First, a first terminal device initiates BR connection to a second terminal device.

The specific procedure of "BR connection" is as follows. Since the first terminal device can take the BR address of the second terminal device of the counterpart from the interface after the previous procedure of the device authentication process. If the first terminal equipment determines that the second broadcast of the second terminal equipment is not received, a physical link is established between the first terminal equipment and the second terminal equipment according to the BR address of the second terminal equipment. The establishment of a physical link is completed between the bottom layer of the first terminal equipment and the bottom layer of the second terminal equipment; if the physical link can be established, confirming that the second terminal equipment of the opposite terminal is in the near field.

After the physical link is successfully established, a callback process is performed, and the establishment of the physical link is completed between the bottom layer of the first terminal device and the bottom layer of the second terminal device, so that a success instruction can be interacted inside the first terminal device, and a success instruction can be interacted inside the second terminal device; and further the BR connection is successful. Wherein the success instruction characterizes the BR connection success between the first terminal device and the second terminal device.

Then, after the BR connection is successful, the first terminal device records the time when the BR connection is successful as a second time t3. The first terminal device determines a first time t4, the first time t4 being 8 seconds after the time at which the first terminal device initiates the BR connection. The first terminal device calculates a time difference w=t4-t 3 between the first time instant t4 and the second time instant t3.

If the first terminal equipment determines that the time difference W is smaller than or equal to the first preset threshold value, the second terminal equipment is determined to be in the near field, and the second terminal equipment cannot be misplaced. The first preset threshold may take 29 seconds.

If the first terminal equipment determines that the time difference W is larger than the first preset threshold value, unicast timeout is determined, unicast confirmation fails, and the second terminal equipment is not in the near field under the high probability. Thereby, the first terminal device kicks off the second terminal device; because the equipment list maintained by the first terminal equipment comprises equipment belonging to the same self-organizing network with the first terminal equipment, the first terminal equipment deletes the second terminal equipment which is off line from the equipment list of the first terminal equipment. The first terminal device no longer displays the second terminal device that is offline in the first interface.

The process of BR unicast acknowledgement provided by the application refers to the following complete process: the first terminal device determines that the second broadcast of the second terminal device is not received within a first time period (21 seconds); establishing BR connection; based on the time difference, it is determined whether to kick the second terminal device off line.

For example, fig. 14 shows a first time axis based on each broadcast according to an embodiment of the present application, and as shown in fig. 14, the coordinates of the axis of fig. 14 are time (in seconds s). The first terminal device is a central node, and the second terminal device is an edge node. The first terminal device transmits a first broadcast, which is a BLE broadcast, every 30 s. The first terminal equipment sends out a first broadcast for the first time at the 0 s; the first terminal equipment sends out a first broadcast for the second time at 30 s; the first terminal equipment sends out a first broadcast for the third time at 60 s; the first terminal device transmits the first broadcast at 90s, the fourth time. The first broadcast is an active broadcast.

After the first terminal device sends out the first broadcast for the first time at the 0 th s, the second terminal device responds to the first broadcast for the first time and sends out a second broadcast which is a BLE broadcast every 20 s. The second terminal device responds to the first broadcast for the first time at the 1 st s and sends out a second broadcast; the second terminal device transmitting a second broadcast in response to the first broadcast for the first time at 21 s; the second terminal device transmits a second broadcast in response to the first broadcast for the first time at 41 s. The second broadcast is a follow-up broadcast.

After the first terminal device sends out the first broadcast for the second time, the second terminal device responds to the first broadcast for the second time, and sends out the second broadcast once every 20s interval, wherein the second broadcast is BLE broadcast. The second terminal device responds to the second first broadcast at 31s and sends out a second broadcast; the second terminal device transmitting a second broadcast in response to the second first broadcast at 51 s; the second terminal device transmits a second broadcast in response to the second first broadcast at 71 s.

And, the first terminal device waits 10 seconds after the 30 th s, the second time of transmitting the first broadcast, at which time it reaches 40 th s. Then, the first terminal device detects whether or not the second broadcast of the second terminal device is received within the past 21 s. If the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21S, the first terminal device performs the above steps S508 to S511.

After the first terminal device sends out the first broadcast for the third time at 60s, the second terminal device responds to the first broadcast for the third time, and sends out a second broadcast which is a BLE broadcast every 20 s. The second terminal device responds to the third first broadcast at 61s to send out a second broadcast; the second terminal device responds to the third first broadcast at 81s to send out a second broadcast; the second terminal device transmits a second broadcast in response to the third first broadcast at 101 s.

And, the first terminal device waits for 10 seconds after the 60 th s, the third time of transmitting the first broadcast, at which time it reaches the 70 th s. Then, the first terminal device detects whether or not the second broadcast of the second terminal device is received within the past 21 s. If the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21S, the first terminal device performs the above steps S508 to S511.

In one example, after step S506, an ad hoc network is obtained, where the ad hoc network includes a plurality of terminal devices. The first terminal equipment is an edge node in the ad hoc network, and the second terminal equipment is an edge node in the ad hoc network; an ad hoc network has a device as a central node.

The central node actively transmits active broadcast once every 30 seconds, and the active broadcast is BLE broadcast.

After the first terminal device receives the active broadcast, the first terminal device transmits the following broadcast every 20 seconds; that is, the first terminal device transmits a first broadcast, which is a BLE broadcast, every 20 seconds after receiving the active broadcast. And the first terminal device may also receive the following broadcast of other edge nodes in the ad hoc network.

The second terminal device transmits a following broadcast every 20 seconds after receiving the active broadcast; that is, the second terminal device transmits a second broadcast, which is a BLE broadcast, every 20 seconds after receiving the active broadcast. And the first terminal device may also receive the following broadcast of other edge nodes in the ad hoc network.

Then, the first terminal device waits for 10 seconds after each first broadcast (first broadcast other than the first time), at which time point t2 is reached. The first terminal device then detects whether a following broadcast of each other edge node is received within the past 21 seconds, so that the first terminal device detects whether a second broadcast of the second terminal device is received within the past 21 seconds.

In case 1, if the first terminal device determines that the second broadcast of the second terminal device is received, the first terminal device continues to execute the process of sending the first broadcast every 20 seconds.

For example, fig. 15 shows a second time axis based on each broadcast according to an embodiment of the present application, as shown in fig. 15, the coordinates of the axes of fig. 15 are time (in seconds s). The first terminal equipment is an edge node, and the second terminal equipment is an edge node; an ad hoc network has a device as a central node.

The active broadcast is an active broadcast.

After the central node sends the active broadcast for the first time, the first terminal device responds to the active broadcast for the first time and sends the first broadcast once every 20 seconds, and the first broadcast is the BLE broadcast. The first terminal equipment responds to the first active broadcast at the 1 st s and sends out a first broadcast; the first terminal device responds to the first active broadcast at 21s to send out a first broadcast; the first terminal device transmits a first broadcast in response to the first active broadcast at 41 s.

The first broadcast is a follow-up broadcast.

And, after the central node transmits the active broadcast for the second time, the second terminal device transmits the second broadcast once every 20s interval in response to the active broadcast for the second time, and the first broadcast is a BLE broadcast.

The second terminal device responds to the third active broadcast at 61s to send out a second broadcast; the second terminal device responds to the third active broadcast at 81s to send out a second broadcast; the second terminal device transmits a second broadcast in response to the third active broadcast at 101 s. The first broadcast is a follow-up broadcast.

And, the first terminal device waits for 10 seconds after the 21 st s, the second transmission of the first broadcast, at which time it reaches 31 st s. Then, the first terminal device detects whether or not the second broadcast of the second terminal device is received within the past 21 s. If the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21S, the first terminal device performs the above steps S508 to S511.

Then, the first terminal device waits for 10 seconds after the first broadcast is transmitted at 31s, at which point 41s is reached. Then, the first terminal device detects whether or not the second broadcast of the second terminal device is received within the past 21 s. If the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21S, the first terminal device performs the above steps S508 to S511.

Then, the first terminal device waits 10 seconds after issuing the first broadcast at 51s, at which point it reaches 61s. Then, the first terminal device detects whether or not the second broadcast of the second terminal device is received within the past 21 s. If the first terminal device determines that the second broadcast of the second terminal device is not received within the past 21S, the first terminal device performs the above steps S508 to S511.

And so on. The first terminal device detects each time after the first broadcast is sent out (the first broadcast is not sent out for the first time).
