Obviously, the embodiments described are only parts of the embodiments of the present application, instead of all the embodiments. All other embodiments obtained by one of ordinary skill in the art based on the embodiments herein without any creative efforts are within the scope of the present application.
In order to solve the problems that a USB cable is required for each communication connection and that mobile devices are subject to area limitations, embodiments of the present application provide a method and apparatus for establishing a communication connection between a mobile device and a fixed device.
First, a method for establishing a communication connection between a mobile device and a fixed device provided by an embodiment of the present application will be described.
In the first aspect, an embodiment of the present application provides a method for establishing a communication connection between a mobile device and a fixed device, from perspective of mobile device.
It should be noted that, in practice, the mobile device may include a handheld device, such as smart phone, tablet computer and the like, and the fixed device may include a device such as desktop computer, laptop computer and the like.
Moreover, a functional software for implementing the method for establishing a communication connection between a mobile device and a fixed device provided in the embodiment may be a dedicated client software installed in a mobile device, or may also be a plug-in of an assistant client software or of a management client software installed in a mobile device. These are reasonable.
As shown in
In S101, a broadcast message containing first connection information related to a fixed device sent by the fixed device is received via a wireless network.
The fixed device may send a broadcast message containing first connection information related to the fixed device via a wireless network when it is required to establish a communication connection between the mobile device and the fixed device. Accordingly, the mobile device may receive, via the wireless network, the broadcast message containing the first connection information related to the fixed device sent by the fixed device.
The way to trigger the establishing of a communication connection between a mobile device and a fixed device may include a manual triggering by a user or a non-manual triggering by a user. For example, as to the manual triggering by a user, the user may perform a predetermined operation on an interaction interface presented by the fixed device to trigger the establishing of a communication connection between a mobile device and a fixed device. The predetermined operation may include but is not limited to an operation of clicking a button, a predetermined gesture operation or the like. As to the non-manual triggering by a user, the user may start a functional software, which implements the method for establishing a communication connection between a mobile device and a fixed device, in the fixed device to automatically trigger the establishing of a communication connection between a mobile device and a fixed device. These are reasonable.
It should be noted that, prerequisites for the implementation of the solution provided by the embodiment are that: (1) the mobile device and the fixed device are in the same wireless network, that is, share the same wireless network; (2) the mobile device has successfully established a communication connection with the fixed device via a USB cable once, and after the mobile device establishes the communication connection with the fixed device via the USB cable, the fixed device sends its own connection information to the mobile device, and the mobile device binds and stores the connection information after receiving the connection information sent by the fixed device. The connection information may include but is not limited to MAC address, IP address, name of the fixed device, etc., wherein the IP address is Internet Protocol address, the MAC (Media Access Control) address is the physical address. The mobile device may store the received connection information of the fixed device into a configuration file, and the present application is not limited thereto.
It will be understood that for the above prerequisites, the fixed device may automatically send its own connection information to the mobile device after the mobile device establishes the communication connection with the fixed device via the USB cable. Of course, the fixed device may pop up an inquiry message about whether the mobile device is to be bound, and when the user issues a binding instruction by responding to the inquiry message, the fixed device sends its own connection information to the mobile device. The inquiry message about whether the mobile device is to be bound may refer to
In S102, it is determined whether the first connection information contained in the received broadcast message matches connection information of a fixed device that has been bound to the mobile device; if the first connection information matches the connection information of the fixed device that has been bound to the mobile device, S103 is performed; otherwise, no operation is performed.
After receiving the broadcast message containing the first connection information related to the fixed device sent by the fixed device, the mobile device may determine whether the first connection information contained in the received broadcast message matches connection information of a fixed device that has been bound to the mobile device, and perform different operations according to different determination results. Specifically, when it is determined that the first connection information contained in the received broadcast message matches the connection information of the fixed device that has been bound to the mobile device, step S103 may be performed to proceed with the establishment process of communication connection. When it is determined that the first connection information contained in the received broadcast message does not match the connection information of the fixed device that has been bound to the mobile device, no operation is performed.
It is to be noted that the connection information of the fixed device that has been bound to the mobile device is received from the fixed device by the mobile device via a Universal Serial Bus (USB) connection when the mobile device is connected to the fixed device via the USB connection, and the mobile device may receive connection information sent by multiple fixed devices and bind and store the connection information.
In S103, a second connection information of the mobile device is returned to the matching fixed device via the wireless network, such that the fixed device sends a connection request to the mobile device according to the second connection information;
when it is determined that the first connection information contained in the received broadcast message matches the connection information of the fixed device that has been bound to the mobile device, the mobile device may return a second connection information thereof to the matching fixed device via the wireless network, so as to cause the fixed device to actively request a communication connection with the mobile device. Thus, the fixed device may, after receiving the second connection information, create a connection request for the mobile device based on the second connection information and send the connection request to the mobile device.
The second connection information of the mobile device may include but is not limited to MAC address, IP address, name of the mobile device and the like.
In S104, the connection request is received to establish a communication connection between the mobile device and the fixed device.
After the connection request sent by the fixed device is received, the communication connection between the mobile device and the fixed device may be established.
It should be noted that, after the connection request is received, a method in the prior art may be used to implement the specific process of establishing the communication connection between the mobile device and the fixed device.
Compared with the prior art, the solution provided by the embodiment only needs to establish a communication connection via a USB cable between the mobile device and the fixed device once, and the subsequent communication connections may be completed without the USB cable. Thus, the solution provided by the embodiment solves the problems that a USB cable is required for each communication connection and that mobile devices are subject to area limitations in the prior art.
Specifically, receiving, via a wireless network, a broadcast message containing first connection information related to a fixed device sent by the fixed device may comprise:
receiving, via the wireless network, the broadcast message containing the first connection information related to the fixed device sent by the fixed device using User Datagram Protocol (UDP).
Accordingly, sending a second connection information of the mobile device to the matching fixed device via the wireless network, may comprise:
sending the second connection information of the mobile device to the matching fixed device via the wireless network using UDP.
The communication protocol used by the fixed device to send a broadcast message is not limited to UDP, and other existing communication protocols may be used. These are reasonable. Moreover, a method in the prior art may be used to implement the receipt of, via a wireless network, a broadcast message containing first connection information related to a fixed device sent by the fixed device using UDP and the returning of a second connection information of the mobile device to the matching fixed device via the wireless network using UDP.
Specifically, in practice, HyperText Transport Protocol (HTTP) may be used to complete the establishment of communication connection. Thus, when the second connection information of the mobile device is returned to the matching fixed device via the wireless network, the solution provided by the embodiment may further comprise:
starting a port listening thread to listen on a preset port based on Hyper Text Transport Protocol (HTTP).
Accordingly, receiving the connection request to establish the communication connection between the mobile device and the fixed device, may comprise:
listening with the port listening thread to obtain an HTTP connection request for the preset port of the mobile device; and
establishing the communication connection between the mobile device and the fixed device, and returning a status code corresponding to a connection success status to the fixed device after the communication connection is established successfully.
It will be understood that the HTTP connection request may include, but not limited to, an HTTP POST request in the prior art. Specifically, in the HTTP POST request, the IP address, preset port, unique identifier string, and operation instruction string information of the mobile device are spliced into a URL link, which is a link with an additional encrypted operation instruction string information. For example, additional data of http://192.168.1.36:100/wifi/api is xlneofneivhdui3w98, which is encrypted and indicates a specified operation instruction. The specific encryption method may be an existing encryption method or a customized encryption method, which is not limited herein.
The preset port that is listened on based on HTTP may be a free port of a mobile device, which is not limited herein. In addition, the preset port may be a pre-agreed port for the mobile device and the fixed device. Furthermore, in practice, a status code corresponding to a connection success status may be but is not limited to 200.
It should be noted that after the connection information of the fixed device is obtained and the HTTP connection request sent by the fixed device is received, the communication connection between the mobile device and the fixed device may be established with contents provided by HTTP. Furthermore, the protocol used in the establishing of the communication connection may be not limited to HTTP, and may be also other protocols in the prior art.
Furthermore, in order to maintain the communication connection between the mobile device and the fixed device, a heartbeat mechanism may be used, wherein the fixed device periodically sends an HTTP inquiry request to the mobile device, and the mobile device feeds back a response message after receiving the HTTP inquiry request. Based on the heartbeat mechanism, after the communication connection between the mobile device and the fixed device is established, the method for establishing a communication connection between a mobile device and a fixed device provided by the embodiment may further comprise:
receiving an HTTP inquiry request periodically sent by the fixed device;
returning a response message corresponding to the HTTP inquiry request to the fixed device.
An HTTP inquiry request is different from an HTTP connection request. Specific contents of the inquiry request may be set according to actual situations, and the response message corresponds to the HTTP inquiry request.
Based on the heartbeat mechanism described above, the method for establishing a communication connection between a mobile device and a fixed device provided by the embodiment may further comprise:
outputting first prompt information when no HTTP inquiry request sent by the fixed device is received for a predetermined period of time, the first prompt information being used to prompt that the communication connection between the mobile device and the fixed device has been disconnected.
The predetermined period of time may be set according to actual situations, which will not be described herein. When an HTTP inquiry request sent by the fixed device is not received for the predetermined period of time, it is indicated that the communication connection between the mobile device and the fixed device has been disconnected. In practice, it is reasonable to only wait for the communication connection request of the fixed device, rather than output the first prompt information.
In the second aspect, an embodiment of the present application provides a method for establishing a communication connection between a mobile device and a fixed device, from perspective of a fixed device.
It should be noted that, in practice, the mobile device may include a handheld device, such as smart phone, tablet computer and the like, and the fixed device may include a device such as desktop computer, laptop computer and the like.
Moreover, the functional software for implementing the method for establishing a communication connection between a mobile device and a fixed device provided in the embodiment may be a dedicated client software installed in the fixed device, or may also be a plug-in of an assistant client software or of a management client software installed in the fixed device. These are reasonable.
As shown in
In S201, a broadcast message containing first connection information of a fixed device is sent via a wireless network when it is required to establish the communication connection between the mobile device and the fixed device.
The fixed device may send a broadcast message containing first connection information related to the fixed device via a wireless network when it is required to establish a communication connection between the mobile device and the fixed device. Accordingly, the mobile device may receive, via the wireless network, the broadcast message containing the first connection information related to the fixed device sent by the fixed device.
The way to trigger the establishing of a communication connection between a mobile device and a fixed device may include a manual triggering by a user or a non-manual triggering by a user. For example, as to the manual triggering by a user, the user may perform a predetermined operation on an interaction interface presented by the fixed device to trigger the establishing of a communication connection between a mobile device and a fixed device. The predetermined operation may include but is not limited to an operation of clicking a button, a predetermined gesture operation or the like. As to the non-manual triggering by a user, the user may start a functional software, which implements the method for establishing a communication connection between a mobile device and a fixed device, in the fixed device to automatically trigger the establishing of a communication connection between a mobile device and a fixed device. These are reasonable.
It should be noted that, prerequisites for the implementation of the solution provided by the embodiment are that: (1) the mobile device and the fixed device are in the same wireless network, that is, share the same wireless network; (2) the mobile device has successfully established a communication connection with the fixed device via a USB cable once, and after the mobile device establishes the communication connection with the fixed device via the USB cable, the fixed device sends its own connection information to the mobile device, and the mobile device binds and stores the connection information after receiving the connection information sent by the fixed device. The connection information may include but is not limited to MAC address, IP address, name of the fixed device and the like. The mobile device may store the received connection information of the fixed device into a configuration file, and the present application is not limited thereto.
It will be understood that for the above prerequisites, the fixed device may automatically send its own connection information to the mobile device after the mobile device establishes the communication connection with the fixed device via the USB cable. Of course, the fixed device may pop up an inquiry message about whether the mobile device is to be bound, and when the user issues a binding instruction by responding to the inquiry message, the fixed device sends its own connection information to the mobile device. The inquiry message about whether the mobile device is to be bound may refer to
It should be noted that after receiving, via the wireless network, the broadcast message containing the first connection information related to the fixed device sent by the fixed device, the mobile device may determine whether the connection information matches those of a fixed device that has been bound to the mobile device. When the connection information matches those of a fixed device that has been bound to the mobile device, the mobile device returns its own second connection information to the matching fixed device via the wireless network. In addition, the connection information of the fixed device that has been bound to the mobile device is received from the fixed device by the mobile device via a USB connection when the mobile device is connected to the fixed device via the USB connection. Further, the mobile device may receive connection information sent by multiple fixed devices and bind and save the connection information. The second connection information of the mobile device may include but is not limited to the MAC address, IP address, name of the mobile device and the like.
In S202, the second connection information related to the mobile device returned by the mobile device is received via the wireless network.
Since the mobile device returns its own second connection information to the fixed device via the wireless network when determining that the first connection information matches the connection information of the fixed device bound thereto, the fixed device may receive, via the wireless network, the second connection information related to the mobile device returned by the mobile device, and thereafter perform the subsequent processing based on the second connection information.
In S203, a connection request for the mobile device is created based on the second connection information.
In S204, the connection request is sent to the mobile device to establish the communication connection between the mobile device and the fixed device.
After the second connection information related to the mobile device is received, the connection request for the mobile device may be created based on the second connection information, and the connection request is sent to the mobile device to establish the communication connection between the mobile device and the fixed device.
Compared with the prior art, the solution provided by the embodiment only needs to establish a communication connection via a USB cable between the mobile device and the fixed device once, and the subsequent communication connections may be completed without the USB cable. Thus, the solution provided by the embodiment solves the problems that a USB cable is required for each communication connection and that mobile devices are subject to area limitations in the prior art.
Specifically, sending, via a wireless network, a broadcast message containing first connection information related to the fixed device may comprise:
sending, via the wireless network, the broadcast message containing the first connection information related to the fixed device using UDP.
Accordingly, receiving, via the wireless network, the second connection information related to the mobile device returned by the mobile device, may comprise:
receiving the second connection information related to the mobile device returned by the mobile device, via the wireless network using UDP.
The communication protocol used by the fixed device to send a broadcast message is not limited to UDP, and other communication protocols in the prior art may be used. These are reasonable. Moreover, a method in the prior art may be used to implement the step of sending, via the wireless network, a broadcast message containing first connection information related to the fixed device and the step of receiving, via the wireless network, the second connection information related to the mobile device returned by the mobile device.
Specifically, HTTP may be used to complete the establishment of communication connection. Therefore, in the solution provided by the embodiment of the present application, creating a connection request for the mobile device based on the second connection information, may comprise:
creating an HTTP connection request for a preset port of the mobile device based on the second connection information.
Accordingly, sending the connection request to the mobile device to establish the communication connection between the mobile device and the fixed device, may comprise:
sending the HTTP connection request for the preset port of the mobile device to the mobile device, such that the mobile device listens with a started port listening thread to obtain the HTTP connection request for the preset port of the mobile device, establishes a communication connection between the mobile device and the fixed device, and returns a status code corresponding to a connection success status to the fixed device after successfully establishing the communication connection; and
receiving the status code corresponding to the connection success status returned by the mobile device to achieve the communication connection between the mobile device and the fixed device.
It will be understood that the HTTP connection request may include, but not limited to, an HTTP POST request in the prior art. Specifically, in the HTTP POST request, the IP address, preset port, unique identifier string, and operation instruction string information of the mobile device are spliced into a URL link, which is a link with an additional encrypted operation instruction string information. For example, additional data of http://192.168.1.36:100/wifi/api is xlneofneivhdui3w98, which is encrypted and indicates a specified operation instruction. The specific encryption method may be an existing encryption method or a customized encryption method, which is not limited herein.
The preset port may be a free port of a mobile device, which is not limited herein. In addition, the preset port may be a pre-agreed port for the mobile device and the fixed device. Furthermore, in practice, a status code corresponding to a connection success status may be but is not limited to 200.
It should be noted that after obtaining the connection information of the fixed device and receiving the HTTP connection request sent by the fixed device, the mobile device may establishes the communication connection between the mobile device and the fixed device with HTTP. Furthermore, the protocol used in the establishing of the communication connection may be not limited to HTTP, and may be also other protocols in the prior art.
Furthermore, in order to maintain the communication connection between the mobile device and the fixed device, a heartbeat mechanism can be used, wherein the fixed device periodically sends an HTTP inquiry request to the mobile device, and the mobile device feeds back a response message after receiving the HTTP inquiry request. Based on the heartbeat mechanism, in a first implementation, after sending the connection request to the mobile device to establish the communication connection between the mobile device and the fixed device, the method for establishing a communication connection between a mobile device and a fixed device provided by the embodiment may further comprise:
sending an HTTP inquiry request periodically to the mobile device; and
re-performing the step of sending the connection request to the mobile device to establish the communication connection between the mobile device and the fixed device, if no response message corresponding to the HTTP inquiry request fed back by the mobile device is received after a predetermined number of times.
When no response message corresponding to the HTTP inquiry request fed back by the mobile device is received after a predetermined number of times, which indicates that the communication connection between the mobile device and the fixed device has been disconnected, a connection request may be sent by the fixed device to the mobile device to establish the communication connection between the mobile device and the fixed device. It will be understood that the predetermined number of times may be set according to actual situations, which will not be described herein.
In a second implementation, after sending the connection request to the mobile device to establish a communication connection between the mobile device and the fixed device, the method for establishing a communication connection between a mobile device and a fixed device provided by the embodiment may further comprise:
sending an HTTP inquiry request periodically to the mobile device; and
outputting a second prompt message if no response message corresponding to the HTTP inquiry request fed back by the mobile device is received after a predetermined number of times, the second prompt message being used to prompt that the communication connection between the mobile device and the fixed device has been disconnected.
When no response message corresponding to the HTTP inquiry request fed back by the mobile device is received after a predetermined number of times, which indicates that the communication connection between the mobile device and the fixed device has been disconnected, a second prompt message is output, wherein the second prompt message is used to prompt that the communication connection between the mobile device and the fixed device has been disconnected.
In practice, the first implementation and the second implementation can be combined. For example, if a response message corresponding to the HTTP inquiry request fed back by the mobile device is not received after a predetermined number of times, the step of sending the connection request to the mobile device to establish the communication connection between the mobile device and the fixed device is re-performed. Further, if the communication connection is still not be successfully established after the reestablishing of the communication connection is performed the predetermined number of times, the second prompt message is output, which is used to prompt that the communication connection between the mobile device and the fixed device has been disconnected. Thus, the user may check the reason of the communication disconnection, and thereby may ensure a successful establishment of the communication connection between the mobile device and the fixed device.
The method for establishing a communication connection between a mobile device and a fixed device provided by embodiments of the present application will be described below in connection with a specific application example. The mobile device is a smart phone with a first mobile phone assistant installed thereon, and the fixed device is a PC provided with a second mobile phone assistant installed thereon. The first mobile phone assistant is a mobile phone side client of a mobile phone assistant A, and the second mobile phone assistant is a PC side client of the mobile phone assistant A.
(1) Binding Process of a New Mobile Phone:
When establishing a communication connection between the PC and the smart phone for the first time, the user may physically connect the smart phone to the PC via a USB cable, and the second mobile phone assistant in the PC and the first mobile phone assistant in the smart phone complete the USB connection between the PC and the smart phone. After the connection is successfully established, the second mobile phone assistant pops up an inquiry message for inquiring whether the user wants to bind them, as shown in
(2) Establishment Process of Communication Connection after Binding
when the second mobile phone assistant in the PC is started again by a user, the second mobile phone assistant sends a broadcast message containing the first connection information related to the PC via a wireless network using UDP, wherein the first connection information includes host name: AAA, IP address: 1.1.1.1, MAC address: X1-X2-X3-X4-X5-X6.
When the first mobile phone assistant in the smart phone in the wireless network is started by the user, the first mobile phone assistant receives the broadcast message sent by the second mobile phone assistant containing the first connection information related to the PC, reads the configuration file autoconnect.xml thereof, starts a port listening thread to listen on the preset port 2000 based on HTTP when determining that the connection information of a PC that has bound to the smart phone matches the first connection information, and returns a second connection information of the smart phone via the wireless network using UDP, wherein the second connection information includes host name: BBB, IP address: 1.1.1.2, MAC address: X7-X8-X9-X0-X1-X2.
the second mobile phone assistant receives the second connection information related to the smart phone returned by the first mobile phone assistant, via the wireless network using UDP, and creates an HTTP POST request based on the second connection information and sends it to the smart phone, which indicates that the PC is ready to start a connection, wherein the HTTP POST request is in the form of a URL, and the URL may be http://1.1.1.2:2000/wifi/api with data xxxx which is an encrypted data.
After receiving the HTTP POST request, the first mobile phone assistant establishes the communication connection between the smart phone and the PC, and returns a status code 200 corresponding to a connection success status to the PC. The second mobile phone assistant receives the status code 200 and completes the establishment of the communication connection between the smart phone and the PC, and then the second mobile phone assistant outputs a prompt information for prompting the user that the communication connection between the smart phone and the PC has been established, such that the user can perform other operations.
(3) Maintenance of Communication Connection Status Based on Heartbeat Mechanism
The second mobile phone assistant accesses the URL http://1.1.1.2:2000/wifi/api with specific encrypted data every 1 second in the form of an HTTP request. The first mobile phone assistant returns the status code 200 corresponding to the connection success status after receiving the access from the second mobile phone assistant of the PC. The second mobile phone assistant receives the status code and determines the connection is in normal status, and then the user can normally perform operations, such as operations of cleaning of the smart phone memory, installing of mobile phone apps and the like.
When the operations are finished, the user closes the second mobile phone assistant. If the first mobile phone assistant does not receive an HTTP request from the second mobile phone assistant for 3 seconds, it is indicated that the communication between the smart phone and the PC has been disconnected.
Thus, the problems that a USB cable is required for each communication connection the smart phone and the PC, and that mobile devices are subject to area limitations in the prior art can be solved by the application embodiment.
