Exemplary method

In order to solve the problems in the prior art, the present disclosure provides a method for implementing connection switching from the perspective of a first host and a second host, respectively, and first introduces the method for implementing connection switching provided by the present disclosure from the perspective of a first host.

Fig. 1 is a flowchart illustrating a method for implementing connection handover according to an exemplary embodiment of the present disclosure. The method shown in fig. 1 is applied to the first host, and the method shown in fig. 1 includes step 110, step 120, step 130 and step 140, which are described below.

Step 110, a list of near field communication devices is scanned.

It should be noted that the Near Field Communication technology involved in the embodiments of the present disclosure includes, but is not limited to, bluetooth (Bluetooth) technology, near Field Communication (NFC) technology, and the like. For convenience of understanding, the following description will be given by taking a case where the near field communication technology is a bluetooth technology as an example, so that the near field communication device referred to hereinafter may be a bluetooth device, and the near field connection referred to hereinafter may be a bluetooth connection; wherein, under some reading pen usage scenarios, bluetooth equipment can be for some reading pen, under other usage scenarios, bluetooth equipment can be mouse, intelligent camera etc..

The first host may have a bluetooth function, and in step 110, on the premise that the bluetooth function of the first host is turned on, by scanning and searching for each bluetooth device near the first host, based on a search result, a near field communication device list may be obtained; at least one near field communication device may be included in the near field communication device list, and each near field communication device in the near field communication device list may be a bluetooth device in the vicinity of the first host.

Step 120, the target near field communication device is screened from the near field communication device list.

Optionally, the signal strengths corresponding to all the near field communication devices in the near field communication device list may be determined, and the near field communication device with the highest corresponding signal strength is selected from the near field communication device list as the target near field communication device; or, randomly screening one near field communication device from the near field communication device list as a target near field communication device; or, the near field communication device list may be presented to the user, and the user selects one near field communication device in the near field communication device list in a voice mode or a touch mode, and the near field communication device selected by the user may be used as the target near field communication device.

Step 130, broadcasting a first notification message under the condition that the target near field communication device is in a connected state; the first notification message is used for representing that the first host requests to be connected to the target near field communication equipment, so that the second host receiving the first notification message disconnects the first near field connection under the condition that the first near field connection is established between the second host and the target near field communication equipment.

Optionally, the near field communication device list may further record respective states of each included near field communication device, where the state of any near field communication device may have two possible situations, namely a connected state and an unconnected state; the connected state indicates that the near field communication equipment currently establishes near field connection with a certain host, and the unconnected state indicates that the near field communication equipment currently does not establish near field connection with any host.

After the target near field communication device has been screened out by performing step 120, the status of the target near field communication device may be determined from the information recorded in the near field communication device list.

If the state of the target near field communication equipment is in an unconnected state, the first host can directly establish near field connection between the first host and the target near field communication equipment according to a standard Bluetooth protocol; the standard Bluetooth protocol may be a Bluetooth Low Energy (BLE) protocol.

If the state of the target near field communication device is a connected state, the first host may generate a first notification message for requesting connection to the target near field communication device according to a standard bluetooth protocol, and broadcast the first notification message, so that each host near the first host can receive the first notification message; the communication distance between each host near the first host and the first host is within the communication range supported by the standard Bluetooth protocol; the first notification message may be in the form of BLE broadcast data.

Assuming that the second host receives the first notification message, the second host may then determine whether a first near field connection is established between itself and the target near field communication device. If a first near-field connection is established between the second host and the target near-field communication equipment, the second host can actively disconnect the first near-field connection; if the first near field connection is not established between the second host and the target near field communication device, the second host does not need to perform a disconnection operation.

A second near field connection is established between the first host and the target near field communication device that has been switched to the unconnected state, step 140.

As described above, the second host may disconnect the first near field connection according to the first notification message, so that the target near field communication device may be switched from a connected state to an unconnected state, and when the target near field communication device is switched to the unconnected state, the second host may establish a second near field connection between itself and the target near field communication device according to a standard bluetooth protocol.

On the basis of the embodiment shown in fig. 1, as shown in fig. 2, the method further comprises a step 121 and a step 123 before the step 130.

In step 121 a first sequence of characters for identifying a target near field communication device is determined.

In one embodiment, step 121 includes:

determining a first MAC address of a target near field communication device based on a device name of the target near field communication device;

from the first MAC address, a first sequence of characters identifying the target near field communication device is intercepted.

Optionally, the near field communication device list may record respective device names of the included near field communication devices, and the device name of any near field communication device may be composed of two parts, which are respectively an agreed prefix and an MAC address of the near field communication device; wherein, the appointed prefix can include any character; the English corresponding to the MAC Address is called Media Access Control Address, and the Chinese corresponding to the MAC Address means Media Access Control Address.

In step 121, the device name of the target near field communication device may be extracted from the near field communication device list, and the MAC address may be extracted from the device name of the target near field communication device as the first MAC address, and then several characters capable of serving as device identification may be intercepted from the first MAC address, and a sequence of the intercepted several characters may be taken as the first character sequence.

In one example, the device name of the target near field communication device is RSDPP _ ABCDEF, RSDPP _ is the agreed prefix, ABCDEF is the first MAC address of the target near field communication device, then CDEF may be truncated from ABCDEF as the first character sequence. Of course, BCDEF may also be truncated from ABCDEF as the first character sequence, depending on the actual situation.

In this embodiment, the first MAC address of the target near field communication device is determined based on the device name of the target near field communication device, and the first MAC address is intercepted, so that the first character sequence for identifying the target near field communication device can be obtained efficiently and reliably.

Of course, the specific implementation of step 121 is not limited to this, for example, the first MAC address itself may be used as the first character sequence, and for example, ABCDEF may be used as the first character sequence.

Step 123, generating a first notification message; the first character sequence is stored in a first preset position in the first notification message, and the connection request identifier is stored in a second preset position in the first notification message.

Alternatively, the request connection identifier may be represented by a first preset character, and the first preset character may be 1 or other characters.

It should be noted that any notification message involved in the embodiments of the present disclosure may include 20 bytes for storing a broadcast Universal Unique Identifier (UUID); the 16 th, 17 th, 18 th, 19 th and 20 th bytes are usable parts, and then the four bytes 16, 17 th, 18 th and 19 th bytes can be used as the first predetermined position, and the 20 th byte position can be used as the second predetermined position.

In generating the first notification message, C may be placed in the 16 th byte, D in the 17 th byte, E in the 18 th byte, F in the 19 th byte, and 1 in the 20 th byte, whereby the first notification message storing the first character sequence and the request connection identification may be generated.

In this way, after receiving the first notification message, according to the connection request identifier stored in the second predetermined location in the first notification message, the second host can determine that the first host has a need to connect to a certain near field communication device, and according to the first character sequence stored in the first predetermined location in the first notification message, the second host can efficiently and reliably determine which near field communication device the first host needs to connect to, and accordingly, the second host can determine whether it needs to perform a disconnection operation.

In one optional example, establishing a second near field connection between the first host and the target near field communication device that has switched to an unconnected state comprises:

under the condition of receiving a second notification message broadcasted by a second host, determining that the target near field communication equipment is switched to an unconnected state, and establishing a second near field connection between the first host and the target near field communication equipment;

Optionally, after the second host successfully disconnects the first near-field connection according to the first notification message, the second host may generate a second notification message for indicating that the second host has disconnected the first near-field connection according to a standard bluetooth protocol, and broadcast the second notification message, so that each host (including the first host) near the second host can receive the second notification message; wherein the second notification message may be in the form of BLE broadcast data.

In case of receiving the second notification message, the first host may determine that the target near field communication device has switched to an unconnected state, and the second host may immediately establish a second near field connection between itself and the target near field communication device according to the standard bluetooth protocol. In this way, by using the reception of the second notification message as a trigger condition for establishing the near field connection, it is possible to efficiently and reliably determine the timing suitable for establishing the second near field connection between the first host and the target near field communication device.

Of course, in specific implementation, the first host may not receive the second notification message as a trigger condition for establishing the near field connection, for example, the first host may periodically scan the near field communication device list, and if it is determined that the device of the target near field communication device is in an unconnected state based on information recorded in the near field communication device list obtained by scanning at a certain time, the first host may establish the second near field connection between itself and the target near field communication device, which is also feasible.

The following describes a method for implementing connection switching provided by the present disclosure from the perspective of the second host.

Fig. 3 is a flowchart illustrating a method for implementing connection switching according to an exemplary embodiment of the present disclosure. The method shown in fig. 3 is applied to the second host, and the method shown in fig. 3 includes

steps

310 and 320, which are described below.

Step 310, receiving a first notification message broadcasted by the first host, wherein the first notification message is used for representing that the first host requests to connect to the target near field communication device.

The second host may have a bluetooth function, and in step 310, the first notification message broadcasted by the first host may be received on the premise that the bluetooth function of the second host is turned on.

In step 320, in case a first near field connection is established between the second host and the target near field communication device, the first near field connection is disconnected.

In the embodiment of the disclosure, after receiving the first notification message broadcast by the first host, the second host may actively disconnect the first near-field connection under the condition that the first near-field connection is established between the second host and the target near-field communication device, so as to ensure that the near-field connection can be successfully established between the first host and the target near-field communication device. Therefore, on the premise of not modifying the hardware of the near field communication equipment, the switching of the host connected with the near field communication equipment can be conveniently and quickly realized through the communication between the hosts, and therefore, the cost for realizing the connection switching can be reduced by the embodiment of the disclosure.

On the basis of the embodiment shown in fig. 3, as shown in fig. 4, the method further includes step 311, step 313, step 315, and step 317 before step 320.

In step 311, in the case that the second host is in the connected state, a second MAC address of the connected near field communication device is determined based on the device name of the connected near field communication device of the second host.

Alternatively, the MAC address may be extracted from the device name of the connected near field communication device of the second host as the second MAC address.

Step 313, a second sequence of characters identifying the connected near field communication device is intercepted from the second MAC address.

It should be noted that, in the specific implementation of step 313, reference may be made to the above description of the manner of obtaining the first character sequence, and details are not described herein again.

A first sequence of characters for identifying the target near field communication device is determined based on the first notification message, step 315.

In step 315, a first sequence of characters can be extracted from a first predetermined location of the first notification message.

In step 317, the connected near field communication device is determined to be the target near field communication device in case the first character sequence matches the second character sequence.

In step 317, it may be determined whether the first character sequence is the same as the second character sequence. If the first character sequence is the same as the second character sequence, the first character sequence can be considered to be matched with the second character sequence, and then the connected near field communication equipment can be determined to be target near field communication equipment, namely, a first near field connection is established between the second host and the target near field communication equipment; if the first character sequence is different from the second character sequence it may be determined that the connected near field communication device is not the target near field communication device, i.e. the first near field connection is not established between the second host and the target near field communication device.

In the embodiment of the disclosure, by comparing the second character sequence obtained for the connected nfc device of the second host with the first character sequence obtained based on the first notification message, whether the first nfc is established between the second host and the target nfc device can be efficiently and reliably determined, so as to determine whether the second host needs to perform a disconnection operation.

On the basis of the embodiment shown in fig. 3, as shown in fig. 5, after step 320, the method further comprises step 330, step 340 and step 350.

Based on the first notification message, a first sequence of characters for identifying the target near field communication device is determined, step 330.

In step 330, a first sequence of characters may be extracted from a first predetermined location of the first notification message.

Step 340, generating a second notification message, where a first character sequence is stored in a first predetermined location in the second notification message, and a connection disconnection identifier is stored in a second predetermined location in the second notification message.

Alternatively, the disconnection indication may be represented by a second preset character, and the second preset character may be 2 or another character.

In step 340, a second notification message may be generated according to the standard bluetooth protocol, and assuming that the first predetermined location in the first notification message stores a CDEF and the second predetermined location in the first notification message stores a 1, the first predetermined location in the second notification message may store a CDEF and the second predetermined location in the second notification message may store a 2.

Step 350, broadcasting a second notification message.

In the embodiment of the disclosure, after the first near field connection is successfully disconnected, the second host may timely notify the first host that the first near field connection is disconnected through generation and broadcast of the second notification message, so that the first host establishes the second near field connection at a proper time.

On the basis of the embodiment shown in fig. 3, as shown in fig. 6, after step 320, the method further comprises step 360 and step 370.

And step 360, starting timing from the moment when the first near field connection is disconnected.

Alternatively, a timer may be set and controlled to start counting from the moment when the first near-field connection is disconnected.

And step 370, establishing a third near field connection between the second host and the target near field communication device when the timing duration reaches a preset duration and the target near field communication device is in an unconnected state.

Alternatively, the preset time period may be 3 seconds, 4 seconds, 5 seconds, 6 seconds or other time periods, which are not listed here.

In the embodiment of the disclosure, when the timing duration of the timer reaches the preset duration, the second host may scan the near field communication device list, and determine the current state of the target near field communication device based on information recorded in the scanned near field communication device list. If the current state of the target near field communication device is an unconnected state, this indicates that the second host has reserved enough connection time for the first host, but the first host has not successfully connected to the target near field communication device, which is likely caused by a failure of the first host, so the second host may actively establish a third near field connection with the target near field communication device, and thus the second host may re-provide service for the user, for example, the user may read a pen through an operating point, so that the second host plays a video that is interesting to the user.

Any of the methods for implementing a connection switch provided by embodiments of the present disclosure may be performed by any suitable device having data processing capabilities, including but not limited to: terminal equipment, a server and the like. Alternatively, any of the methods for implementing connection switching provided by the embodiments of the present disclosure may be executed by a processor, for example, the processor executes any of the methods for implementing connection switching mentioned by the embodiments of the present disclosure by calling a corresponding instruction stored in a memory. And will not be described in detail below.
