[0002] Currently, when establishing a network connection between a connecting device and a connected device, the connection method used is as follows: the user manually inputs parameters such as the IP address of the connected device into the connecting device, and then the connecting device establishes a network connection with the connected device based on the parameters input by the user.

[0067] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0068] To improve the efficiency of establishing a connection between the connecting device and the connected device, embodiments of this application provide a device connection method, apparatus, electronic device, computer-readable storage medium, and computer program product. The device connection method provided by the embodiments of this application will be introduced first.

[0069] The device connection method provided in this application can be applied to any connection-end device that needs to establish a connection with the connected end device, such as a computer, tablet computer, or mobile phone, etc., without specific limitation. For clarity, it will be referred to as the connection-end device below.

[0070] like Figure 1 As shown, a device connection method is applied to a connection-end device, the method comprising:

[0071] S101, when a connection instruction is obtained for the shortcut corresponding to the connected device, the IP address and identifier of the connected device corresponding to the shortcut are obtained from the pre-stored shortcut.

[0072] S102, establish a connection with the connected device based on the IP address and identifier of the connected device.

[0073] In the solution provided in this application, when the connecting device receives a connection command for a shortcut corresponding to the connected device, it can obtain the pre-stored IP address and identifier of the connected device corresponding to the shortcut; and establish a connection with the connected device based on the IP address and identifier of the connected device. Since the connecting device can directly establish a connection with the connected device based on the pre-stored IP address and identifier of the connected device when it receives a connection command for a shortcut corresponding to the connected device, it eliminates the need for the user to manually input parameters such as the IP address of the connected device, thereby improving the efficiency of establishing a connection between the connecting device and the connected device.

[0074] After establishing a connection with the connected device for the first time, the connecting device can obtain the IP address and identifier of the connected device. Based on these identifiers, it can then generate a shortcut for the connected device. Subsequent times when the connecting device wants to re-establish a connection, it can activate this shortcut to complete the necessary pre- and post-connection operations, thus achieving a quick connection.

[0075] Therefore, when the connecting device receives a connection command for the shortcut corresponding to the connected device, it can activate the shortcut and obtain the pre-stored IP address and identifier of the connected device corresponding to the shortcut.

[0076] In one implementation, when the connecting device generates a shortcut for the connected device based on the IP address and identifier of the connected device, it can write the IP address and identifier of the connected device into the startup parameters of the shortcut. In this way, when the connecting device receives a connection command for the shortcut, it can read the IP address and identifier of the connected device from the startup parameters of the shortcut.

[0077] After obtaining the IP address and identifier of the connected device, the connecting device can establish a connection with the connected device based on these two identifiers. Specifically, the connecting device can first establish a network connection with the connected device using its corresponding shortcut and based on the connected device's IP address. If the network connection fails to establish, it indicates that the IP address of the connected device may have changed. In this case, the connecting device can locate the connected device based on its fixed identifier and thus establish a connection.

[0078] In one implementation, when the connection between the connecting device and the connected device is a connection between an application on the connecting device and an application on the connected device, the connecting device can also pre-store the port information of the connected device corresponding to the shortcut. Based on this, when establishing a connection with the connected device, the connecting device can first establish a device-to-device connection using IP address and device identifier, and then establish a connection between the device and its application based on the port number, thereby realizing the connection between the application on the connecting device and the application on the connected device.

[0079] In the solution provided in this application, when the connecting device receives a connection command for a shortcut corresponding to the connected device, it can directly establish a connection with the connected device based on the pre-stored IP address and identifier of the connected device corresponding to the shortcut, without requiring the user to manually input parameters such as the IP address of the connected device. This improves the efficiency of establishing a connection between the connecting device and the connected device. Furthermore, when the IP address of the connected device remains unchanged, the connecting device can directly establish a connection with the connected device based on the obtained IP address via the shortcut. When the IP address of the connected device changes, the connecting device can also establish a connection based on the obtained identifier of the connected device. Because the identifier of the connected device does not change, even if the MAC address of the connected device changes, the connecting device can still find the connected device based on the fixed identifier and establish a connection. Therefore, this improves the success rate of establishing a connection between the connecting device and the connected device via the shortcut.

[0080] As one implementation method of this application, such as Figure 2 As shown, establishing a connection with the connected device based on the IP address and identifier of the connected device may include:

[0081] S201, a network connection request is sent to the IP address of the connected terminal device.

[0082] After obtaining the IP address and identifier of the connected device, the connecting device can first send a network connection request to the IP address of the connected device to determine whether the IP address is available.

[0083] In one implementation, the connecting device can send a network connection request to the IP address of the connected device, and then monitor whether it receives response data from the connected device within a preset time period. If it receives response data from the connected device within the preset time period, it determines that the IP address is available; if it does not receive response data from the connected device within the preset time period, it determines that the IP address is unavailable.

[0084] S202, if the network connection with the connected device fails through the IP address, the identifier of the alternative device is detected by a preset device detection method.

[0085] If the connecting device cannot establish a network connection with the connected device using the IP address of the connected device, i.e., the network connection fails, it means that the IP address of the connected device may have changed, and it is no longer possible to establish a network connection with the connected device based on the pre-stored IP address of the connected device.

[0086] However, the connected device may still be on the same network as the connecting device, or within the preset range of the connecting device. In this case, the connected device can use the preset device detection method to detect the identifiers of various devices on the same network as the connecting device, or the identifiers of various devices within the preset range of the connecting device, and use them as alternative device identifiers.

[0087] S203, if the identifier of the connected end device exists in the candidate device identifiers, send a connection request to the connected end device to establish a connection with the connected end device.

[0088] Because there may be multiple devices in the same network as the connecting device or within the preset range of the connecting device, and these devices may or may not include the connected device, the connecting device can determine whether there is a connected device among the candidate device identifiers after detecting each candidate device identifier. That is, it can determine whether there is a connected device among the devices in the same network as the connecting device or within the preset range of the connecting device.

[0089] If the candidate device identifier contains the identifier of the connected device, it means that the connected device is in the same network as the connected device, or that the connected device exists among the devices within the preset range of the connected device. Therefore, after determining that the candidate device identifier contains the identifier of the connected device, the connected device can determine the device corresponding to the connected device identifier based on the identifier of the connected device, take it as the connected device, and then send a connection request to the connected device to establish a connection with the connected device.

[0090] The connection method for the connecting device to send a connection request to the connected device and establish a connection can be either to send a connection request to the connected device through a preset connection method and then directly establish a connection with the connected device, or to first send a connection request to the connected device to obtain the IP address of the connecting device, and then establish a network connection with the connected device based on the IP address. No specific limitation is made here.

[0091] If the identifier of the connected device is not among the candidate device identifiers, it means that the connected device is in the same network as the connected device, or that the connected device is not among the devices in the preset range of the connected device. Therefore, after determining that the connected device identifier is not among the candidate device identifiers, the connected device can determine that the connection has failed.

[0092] In the solution provided in this application embodiment, after obtaining the IP address and identifier of the connected device, the connecting device can first attempt to establish a network connection with the connected device based on its IP address. If a network connection can be established, a simple and efficient fast connection can be achieved. If a network connection cannot be established, the connecting device can also detect the identifiers of various candidate devices based on a preset device detection method, and then determine whether the connected device has been detected based on its identifier. If detected, a connection can be established with the connected device based on its identifier, thereby improving the success rate of establishing a connection between the connecting device and the connected device via a shortcut.

[0093] As one implementation of this application, the above-mentioned detection of candidate device identifiers through a preset device detection method may include:

[0094] The identifiers of devices in the same network as the connection device are obtained through multicast detection and used as candidate device identifiers; or, the identifiers of devices with the wireless network direct connection function enabled within a preset range of the connection device are obtained through wireless network direct connection and used as candidate device identifiers.

[0095] Accordingly, the above-mentioned connection establishment with the connected device based on the connected device identifier may include:

[0096] If the identifier of the connected device is detected by multicast, obtain the IP address returned by the connected device based on the multicast; send a network connection request to the connected device based on the IP address returned by the multicast to establish a network connection with the connected device; or, if the identifier of the connected device is detected by direct wireless network connection, send a wireless network connection request to the connected device through direct wireless network connection to establish a wireless network connection with the connected device.

[0097] In one implementation, after the connecting device fails to connect to the network of the connected device via the IP address of the connected device, the connecting device performs a detection using a preset device detection method, and the method for establishing a connection with the connected device can be as follows: Figure 3 As shown:

[0098] S301, the identifier of the device in the same network as the connection device is obtained through multicast detection, and used as the candidate device identifier.

[0099] If the connecting device fails to establish a network connection with the connected device through the IP address of the connected device, it can enable the multicast function to detect the identifiers of devices in the same network as the connecting device, and use them as alternative device identifiers.

[0100] S302, determine whether the identifier of the connected end device exists in the candidate device identifiers. If it exists, proceed to step S303; if it does not exist, determine that the connection has failed.

[0101] After detecting the candidate device identifier, the connecting device can determine whether the connected device identifier exists among the candidate device identifiers, that is, whether the connected device exists among the devices in the same network as the connecting device.

[0102] S303, obtain the IP address returned by the connected device based on the multicast; send a network connection request to the connected device based on the IP address returned by the multicast to establish a network connection with the connected device.

[0103] When the connecting device detects the identifier of the connected device in multicast, that is, when the identifier of the connected device is among the candidate device identifiers, the connecting device can obtain the IP address of the device corresponding to the connected device identifier, that is, obtain the IP address of the connected device. Then, the connecting device can send a network connection request to the connected device based on the IP address to establish a network connection with the connected device.

[0104] In one scenario, the device's response data to multicast may include the device's IP address. In this case, after determining that the connected device identifier exists among the candidate device identifiers, the connecting device can parse the multicast response data of the device corresponding to that connected device identifier, that is, parse the multicast response data of the connected device to obtain the IP address of the connected device.

[0105] When the connection between the connecting device and the connected device is a connection between an application in the connecting device and an application in the connected device, the response data may also include the port number used by the application in the connected device.

[0106] In another scenario, the device's response data to multicast does not include the device's IP address. In this case, after determining that the candidate device identifier contains the identifier of the connected device, the connecting device can send an IP address acquisition request to the device corresponding to that identifier, i.e., the connected device. This causes the connected device to return an IP address to the connecting device based on the IP address acquisition request, thus enabling the connecting device to obtain the IP address of the connected device.

[0107] In another implementation, after the connecting device fails to connect to the network of the connected device via the IP address of the connected device, the connecting device probes using a preset device detection method, and the method for establishing a connection with the connected device can be as follows: Figure 4 As shown:

[0108] S401, by means of wireless network direct connection, detect the identifier of the device that has enabled wireless network direct connection function within the preset range of the connection terminal device, and use it as the candidate device identifier.

[0109] After failing to establish a network connection with the connected device via the IP address of the connected device, the connecting device can determine whether it supports the wireless network direct connection function, that is, whether it supports the Wi-Fi Direct function. If it does, it enables the wireless network direct connection function and detects the identifiers of devices that have enabled the wireless network direct connection function within the preset range of the connecting device through the wireless network direct connection method, which are used as alternative device identifiers.

[0110] S402, determine whether the identifier of the connected end device exists in the candidate device identifiers. If it exists, proceed to step S403; if it does not exist, determine that the connection has failed.

[0111] After detecting the candidate device identifier, the connecting device can determine whether the connected device identifier exists among the candidate device identifiers, that is, whether the connected device exists among the devices that have enabled the wireless network direct connection function within the preset range of the connecting device.

[0112] S403, a wireless network connection request is sent to the connected device via a direct wireless network connection to establish a wireless network connection with the connected device.

[0113] When the connecting device detects the identifier of the connected device through the wireless network direct connection, that is, when the identifier of the connected device is among the candidate device identifiers, it can directly send a wireless network connection request to the connected device through the wireless network direct connection method to establish a wireless network connection with the connected device. In other words, it establishes a Wi-Fi Direct connection with the connected device through the wireless network direct connection method without needing to obtain the IP address of the connected device.

[0114] In the solution provided in this application embodiment, after the connecting device fails to establish a network connection with the connected device through the IP address of the connected device, it can choose to detect the device identifier of the device in the same network as the connecting device through multicast, or it can choose to detect the device identifier of the device with the wireless network direct connection function enabled within the preset range of the connecting device through wireless network direct connection. Then, when the identifier of the connected device is found in the detected device identifier, it can connect to the connected device, thereby improving the success rate of the connecting device establishing a connection with the connected device through a shortcut.

[0115] As one implementation method of this application, such as Figure 5 As shown, after step S302, the method may further include:

[0116] S304, by means of wireless network direct connection, detect the identifier of the device that has enabled wireless network direct connection function within the preset range of the connection terminal device, and use it as the alternative device identifier.

[0117] If the connecting device fails to establish a network connection with the connected device via the IP address of the connected device, and if the connected device's identifier is not detected via multicast (i.e., the connected device's identifier is not among the candidate device identifiers detected by multicast), in order to ensure that the connecting device and the connected device can successfully establish a connection, the connecting device can try to detect the connected device again via a direct wireless network connection.

[0118] Specifically, the connecting device can determine whether it supports the wireless network direct connection function. If it does, it enables the wireless network direct connection function and detects the identifiers of devices that have enabled the wireless network direct connection function within the preset range of the connecting device through the wireless network direct connection method, which are then used as candidate device identifiers.

[0119] S305, determine whether the connected end device identifier exists in the candidate device identifiers. If it exists, proceed to step S306; if it does not exist, proceed to step S307.

[0120] S306, A wireless network connection request is sent to the connected device via a direct wireless network connection to establish a wireless network connection with the connected device.

[0121] Steps S305-S306 are the same as steps S402-S403, and will not be repeated here.

[0122] S307, connection failed.

[0123] If the identifier of the connected device is not found in either the multicast or wireless network direct connection method among the candidate device identifiers, it means that the connected device is in the same network as the connected device and that there is no connected device among the devices within the preset range of the connected device. Therefore, after the connected device determines in step S305 that there is no connected device identifier among the candidate device identifiers, it can proceed to step S307 to determine that the connection has failed.

[0124] In the solution provided in this application embodiment, after the connecting device fails to establish a network connection with the connected device through the IP address of the connected device, it can first detect the identifier of the connected device through multicast. If multicast cannot detect the identifier of the connected device, it can further detect the identifier of the connected device through the wireless network direct connection method. In this way, the connected device can be detected in both the network distance dimension and the real distance dimension, thereby increasing the probability of discovering the connected device and thus increasing the success rate of the connecting device establishing a connection with the connected device through the shortcut.

[0125] As one implementation method of this application, such as Figure 6 As shown, after step S402, the method may further include:

[0126] S404, the identifier of the device in the same network as the connection device is obtained through multicast detection, and used as the candidate device identifier.

[0127] If the connecting device fails to establish a network connection with the connected device through the IP address of the connected device, and if the connected device's identifier is also not detected through the wireless network direct connection method (i.e., the connected device's identifier is not among the candidate device identifiers detected by the wireless network direct connection), in order to ensure that the connecting device and the connected device can successfully establish a connection, the connecting device can re-probe the connected device through multicast.

[0128] Specifically, the connection device can enable multicast functionality and use multicast to detect the identifiers of devices in the same network as the connection device, which can then be used as alternative device identifiers.

[0129] S405, determine whether the connected end device identifier exists in the candidate device identifiers. If it exists, proceed to step S406; if it does not exist, proceed to step S407.

[0130] S406, obtain the IP address returned by the connected device based on the multicast; send a network connection request to the connected device based on the IP address returned by the multicast to establish a network connection with the connected device.

[0131] The steps S405-S406 described above are the same as those S302-S303 described above, and will not be repeated here.

[0132] S407, connection failed.

[0133] If the identifier of the connected device is not found in either the multicast or wireless network direct connection method among the candidate device identifiers, it means that the connected device is in the same network as the connected device and that there is no connected device among the devices within the preset range of the connected device. Therefore, after the connected device determines in step S405 that there is no connected device identifier among the candidate device identifiers, it can proceed to step S407 to determine that the connection has failed.

[0134] In the solution provided in this application embodiment, after the connecting device fails to establish a network connection with the connected device through the IP address of the connected device, it can first detect the identifier of the connected device through the wireless network direct connection method. If the wireless network direct connection method cannot detect the identifier of the connected device, it can further detect the identifier of the connected device through multicast. In this way, the connected device can be detected in both the network distance dimension and the real distance dimension, thereby increasing the probability of discovering the connected device and thus increasing the success rate of the connecting device establishing a connection with the connected device through the shortcut.

[0135] As one implementation method of this application, such as Figure 7 As shown, prior to step S202 above, the method may further include:

[0136] S701, determine whether the IP address is available based on the response to the network connection request. If it is available, proceed to step S702; if it is not available, proceed to step S202.

[0137] After sending a network connection request to the IP address of the connected device, the connecting device can determine whether the IP address is available based on the IP address's response to the network connection request.

[0138] For example, after sending a network connection request to the IP address of the connected device, the connecting device can monitor whether it receives a response from the connected device within a preset time period. If a response is received within the preset time period, the IP address is determined to be available; if no response is received within the preset time period, the IP address is determined to be unavailable.

[0139] If the IP address is determined to be unavailable based on the response to the network connection request, it can be determined that the network connection with the connected device has failed. Then the connecting device can execute step S202, in the case of failure to connect to the network with the connected device via IP address, to detect the identifier of the alternative device through a preset device detection method.

[0140] If the IP address is determined to be available based on the response to the network connection request, the connecting device can execute steps S702-S703 to further determine whether the device currently using the IP address is the connected device.

[0141] S702, obtain the device identifier corresponding to the IP address.

[0142] Once the connection device determines that the IP address is available, it can further obtain the device identifier corresponding to that IP address, that is, obtain the device identifier of the device currently using that IP address.

[0143] In one implementation, the device's response data to the network connection request may include the device's IP address. In this way, after receiving the response data returned from the IP address, the connecting device can determine that the IP address is available and parse the response data to obtain the device identifier corresponding to the IP address.

[0144] In another implementation, the device's response data to the network connection request may not include the device's IP address. In this way, after the connecting device receives the response data returned from the aforementioned IP address and determines that the IP address is available, it can send an IP address acquisition request to the device corresponding to the IP address. This causes the device corresponding to the IP address to return an IP address to the connecting device based on the IP address acquisition request, so that the connecting device can obtain the device identifier corresponding to the IP address.

[0145] S703, determine whether the obtained device identifier is the same as the identifier of the connected end device. If they are the same, proceed to step S704; if they are not the same, proceed to step S202.

[0146] If the device identifier corresponding to the IP address is obtained, it means that a device is currently using the IP address of the connected device. However, this device could be the connected device or another device. Therefore, after obtaining the device identifier corresponding to the IP address, the connecting device can compare the obtained device identifier with the connected device identifier corresponding to the pre-stored shortcut to determine whether the two are the same, that is, to determine whether the device currently using the IP address is the connected device.

[0147] If the obtained device identifier is different from the identifier of the connected device, it means that the device currently using the IP address is not the connected device, and it is determined that the network connection with the connected device has failed. Then the connecting device can execute step S202, in the case of failure to connect to the network of the connected device by IP address, to detect the alternative device identifier by a preset device detection method.

[0148] If the obtained device identifier is different from the identifier of the connected device, it means that the device currently using the IP address is the connected device. At this time, the connecting device can execute step S704.

[0149] S704, a network connection request is sent to the connected device using the IP address of the connected device to establish a network connection with the connected device.

[0150] If the connecting device determines that the IP address of the connected device corresponding to the shortcut is available, and determines that the device identifier corresponding to the obtained IP address is the same as the identifier of the connected device, it means that the connected device is still using the IP address. Therefore, the connecting device can send a network connection request to the connected device through the IP address of the connected device to establish a network connection with the connected device.

[0151] In the solution provided in this application embodiment, the connecting end device can first send a network connection request to the IP address of the connected end device, and then determine whether the IP address is available based on the response to the network connection request. If the IP address is available, it can further determine whether the device currently using the IP address is the connected end device. If the device currently using the IP address is the connected end device, then a network connection request is sent to the connected end device through the IP address of the connected end device to establish a network connection with the connected end device, thereby improving the accuracy of establishing the connection.

[0152] As one embodiment of this application, after establishing a connection with the connected end device as described above, the method may further include:

[0153] Based on the IP address of the connected device corresponding to the successful establishment of the connection, the pre-stored IP address of the connected device is updated.

[0154] To enable subsequent connection processes to quickly establish a connection with the connected device by launching a shortcut and using the IP address of the connected device corresponding to the shortcut, the connecting device can update the pre-stored IP address of the connected device based on the IP address of the connected device corresponding to the successful connection after establishing a connection.

[0155] In one implementation, when the connecting device establishes a network connection with the connected device based on the IP address returned by multicast, since the connected device returns an IP address to the connecting device when responding to the multicast, the connecting device can directly use the IP address returned by multicast as the IP address of the connected device corresponding to the successful establishment of the connection, and then update the pre-stored IP address of the connected device based on this IP address.

[0156] In another implementation, when the connecting device establishes a wireless network connection with the connected device via a direct wireless network connection, since it is not necessary to obtain or use the IP address of the connected device during the establishment of the wireless network connection, the connecting device can send an identifier acquisition request to the IP address of the connected device after establishing the wireless network connection to obtain the IP address of the connected device, use it as the IP address of the connected device corresponding to the successful establishment of the connection, and then update the pre-stored IP address of the connected device based on this IP address.

[0157] In the solution provided in this application embodiment, after establishing a connection with the connected device, the connecting device can update the pre-stored IP address of the connected device based on the IP address of the connected device corresponding to the successful connection. This allows subsequent connection processes to quickly establish a connection with the connected device by launching a shortcut and using the IP address of the connected device corresponding to the shortcut.

[0158] As one embodiment of this application, the identifier of the connected device can be generated based on the hardware serial number of the connected device, the initial MAC address of the connected device, or randomly generated. The identifier of the connected device is used to uniquely identify the connected device and remains fixed.

[0159] In one implementation, the identifier of the connected device can be a GUID (Globally Unique Identifier). The GUID can be generated by directly using the hardware serial number or initial MAC address of the connected device, by adding a random number to the hardware serial number or initial MAC address of the connected device, or by generating a random number and directly using the random number as the GUID. No specific limitation is made here.

[0160] In the method of generating random numbers and directly using the random number as a GUID, in order to avoid generating the same random number, non-random parameters such as time can be added to the random number generation algorithm.

[0161] In the solution provided in this application embodiment, the identifier of the connected device can be generated based on the hardware serial number of the connected device, the initial MAC address of the connected device, or randomly generated, to uniquely identify the connected device, and remains unchanged. In this way, even if the IP address of the connected device changes, or the network card of the connected device is replaced, causing the MAC address of the connected device to change, the connected device can be identified through the device identifier of the connected device because the device identifier is used to uniquely identify the connected device and remains unchanged, thereby enabling the connecting device to establish a connection with the connected device.

[0162] The following is based on Figure 8 For example, let's introduce a device connection method provided in an embodiment of this application:

[0163] When the connecting device receives a connection instruction for the shortcut corresponding to the connected device, it can first activate the shortcut and then execute step S801 to obtain the IP address and GUID from the startup parameters, i.e., obtain the IP address and identifier of the connected device. Then, the connecting device can execute step S802 to determine if the IP address can be used for network connection, i.e., determine if the IP address is available. If it is, the connecting device can execute step S803 to further determine if the device's GUID matches the GUID in the startup parameters, i.e., determine if the device identifier corresponding to the obtained IP address is the same as the identifier of the connected device in the shortcut's startup parameters. If they are the same, a network connection request can be sent to the connected device using the connected device's IP address to establish a network connection. Then, step S804 can be executed to confirm a successful connection.

[0164] If the judgment result of step S802 or step S803 is negative, the connecting device can execute step S806, multicast detection device, that is, obtain the identifier of the device in the same network as the connecting device through multicast detection, as a candidate device identifier. Then the connecting device can execute step S807, filter the existence of the device by GUID, that is, determine whether the identifier of the connected device exists among the candidate device identifiers. If it exists, the IP address returned by the connected device based on multicast can be obtained. Through this IP address, a network connection request is sent to the connected device to establish a network connection with the connected device. Then step S804 can be executed to confirm the connection is successful.

[0165] If not, the connecting device can execute step S808 to determine whether Wi-Fi Direct is supported, i.e., whether it has Wi-Fi Direct functionality. If not, the connecting device can execute step S812 to determine that the connection has failed. If supported, it can execute step S809 to detect devices via Wi-Fi Direct, i.e., to detect the identifiers of devices with Wi-Fi Direct enabled within the preset range of the connecting device via wireless network direct connection, and use them as candidate device identifiers. Then, it can execute step S810 to filter whether devices exist by GUID, i.e., to determine whether the identifier of the connected device exists among the candidate device identifiers. If not, it executes step S812 to determine that the connection has failed. If it exists, it executes step S811 to establish a Wi-Fi Direct connection, i.e., to send a wireless network connection request to the connected device via wireless network direct connection to establish a wireless network connection with the connected device. Then, it executes step S804 to determine that the connection is successful.

[0166] After the connecting device successfully connects to the connected device via multicast or direct wireless network connection, the IP address of the connected device changes. Therefore, the connecting device can execute step S805 to update the shortcut startup parameters after the connection is successful. That is, based on the IP address of the connected device corresponding to the successfully established connection, the connecting device updates the IP address of the pre-stored shortcut corresponding to the connected device.

[0167] After completing step S805 to update the shortcut startup parameters or after completing step S812 to confirm the connection failure, the device connection method execution ends.

[0168] In the solution provided in this application embodiment, when the connecting device receives a connection instruction for a shortcut corresponding to the connected device, it can obtain the pre-stored IP address and identifier of the connected device corresponding to the shortcut; and establish a connection with the connected device based on the IP address and identifier of the connected device. Since the connecting device can obtain the IP address and identifier of the connected device when it receives the connection instruction for the shortcut, when the IP address of the connected device remains unchanged, the connecting device can directly establish a connection with the connected device based on the obtained IP address via the shortcut. When the IP address of the connected device changes, the connecting device can still establish a connection based on the obtained identifier of the connected device. Because the identifier of the connected device does not change, even if the MAC address of the connected device changes, the connecting device can still find the connected device based on the fixed identifier and establish a connection. Therefore, the success rate of the connecting device establishing a connection with the connected device via the shortcut is improved.

[0169] Corresponding to the above-described device connection method, this application also provides a device connection apparatus, which will be described below.
