Description
[ field of technology ]
The present invention relates to the field of the internet, and in particular, to a method and apparatus for controlling network connection of a terminal.
[ background Art ]
Mobile printing is now increasingly used. An image forming apparatus such as a printer supports WI-FI connection, and a user can establish a wireless connection with the printer through a cellular phone, and send a print job to the printer through the cellular phone.
In the prior art, the printer has a soft AP (Access Point) function, that is, the printer can be used as an Access Point to send out a broadcast, wherein the broadcast includes an SSID (Service Set Identifier ), the mobile phone can search the SSID, and after the user selects the SSID from Wi-Fi settings of the mobile phone and inputs a password, the mobile phone and the printer are directly connected. However, in this connection mode, the mobile phone cannot perform web page printing or other functions requiring access to the internet.
As shown in fig. 1, the printer 103 itself includes an access point 105, and broadcasts a broadcast including the SSID of the access point 105. The handset 104 may search for the SSID of the access point 105, establish a connection with the access point 105 based on the SSID of the access point 105 and the corresponding authentication key to search for the printer 103 to establish a direct connection therewith without establishing a connection through other access points.
An APP (Application) of the printer 103 is installed in the mobile phone 104, and the APP of the printer searches for the printer 103 to establish communication therewith through the access point 105. When the user exits the APP, the Wi-Fi connected access point 105 of the handset 104, also the printer 103, cannot access the internet. The prior art method is that after the user exits the APP of the printer, the Wi-Fi of the mobile phone 104 is set to be connected to the access point 101, so that operations such as accessing the internet can be performed through the access point 101. If the printer 103 is also to be reused, the user needs to set up the Wi-Fi connection of the handset to the printer's access point 105. Alternatively, when both the mobile phone 104 and the printer 103 are connected to the access point 101, the APP of the mobile phone 104 searches for the printer 103 via the access point 101 to establish communication, so that even if the user exits the APP, the mobile phone is still connected to the access point 101, and other operations for accessing the internet can be continued. However, the process of configuring the printer 103 to connect to the access point 101 is very complicated, and it is generally necessary that the printer 103 has a setup panel through which the SSID and the key of the access point 101 are input, or that the printer 103 is connected to a computer by USB, and the SSID and the key of the access point 101 are input through a screen and a keyboard of the computer.
The prior art is very cumbersome and requires a large number of manual input operations to be performed by the user. It is very confusing for users lacking network knowledge and is prone to operational errors.

In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Example 1
Fig. 2 is a flowchart of an alternative method for controlling network connection of a terminal according to an embodiment of the present invention, as shown in fig. 2, where the method includes:
step S102: and judging whether to exit the target application program.
Step S104: if the target application program is subjected to the exit operation, judging whether the network switching condition is met.
Step S106: and if the network switching condition is met, the control terminal disconnects the network connection with the access point currently connected with the control terminal when the target application program performs the exit operation.
The terminal may be a cell phone, a computer or other electronic device.
The target application refers to APP of an image forming apparatus, which is an apparatus that prints data on a recording medium such as printing paper. The image forming apparatus includes a copier, a printer, a facsimile machine, a scanner, and a multi-functional peripheral that performs the above functions in a single device. An image forming apparatus such as a printer supports WI-FI connection, and a user can establish a wireless connection with the printer through a cellular phone, and send a print job to the printer through the cellular phone.
The exit of the target application may refer to any of the following: the user exits the target application program under the operating system running environment of the terminal; the user exits the interface of the target application program and enters the interfaces of other application programs, and the target application program only runs in the background; the target application is forced to exit or abnormally end in the operating system running environment of the terminal.
In the embodiment of the invention, whether the target application program is subjected to the exit operation is judged, if the target application program is subjected to the exit operation, whether the network switching condition is met is judged, if the network switching condition is met, the control terminal disconnects the network connection with the access point currently connected with the control terminal when the target application program is subjected to the exit operation, the problem of complicated network switching operation in the prior art is solved, and the technical effect of simply and rapidly switching the network is achieved.
For example, when the APP is installed on the mobile phone and exits the APP or the APP is in background operation, the connection between the mobile phone and the access point of the printer is automatically cut off, so that the mobile phone is connected to the access point connected before the access point connected to the printer. When the user logs in the APP again, the APP acquires the stored unique identification information of the printer connected before and the service set identifier and the key of the corresponding access point, so that the mobile phone is connected to the access point of the printer, and the APP establishes communication with the printer connected before again.
Specifically, as shown in fig. 1, before communication is established with the printer 103, the mobile phone 104 is being connected to the access point 101, when searching for a printer at the APP, the APP can search not only for a printer connected to the access point 101 but also for an access point 105 included in the printer 103 through the access point 101, and when a user selects a printer associated with the access point 105, the APP causes the mobile phone to connect to the access point 105 of the printer and establish communication with the printer 103, and records unique identification information of the connected printer 103 and information such as a service set identifier and a key of the access point 105 of the corresponding printer. The unique identification information of the printer may be a host name or a manufacturer serial number of the printer. The APP will detect whether the user operates to log out of the APP, or monitor whether log-in of the user occurs, and when detecting that the predetermined condition of logging out of the APP is satisfied, the APP prompts network switching to the operating system of the mobile phone 104, and causes the mobile phone 104 to disconnect from the access point 105. The mobile phone 104 automatically switches to the access point 101 before connection after receiving the network switching instruction of the APP, so that when the user exits the APP, the mobile phone can be automatically switched to the network which can access the Internet. When the APP is logged in again, the APP obtains the stored unique identification information of the printer 103 and the service set identifier and the key of the corresponding access point 105, and makes the mobile phone establish connection with the access point 105 according to the service set identifier and the key of the access point 105, and the APP searches the printer 103 for communication with the stored unique identification information of the printer 103, and displays the unique identification information, manufacturer information, model information, and the like of the connected printer 103 on the interface of the APP.
According to the embodiment of the invention, various manual operation mobile phones are prevented from carrying out network switching when a user uses the printer and connects an access point of the printer, the problem of complex network switching steps is solved, the user is convenient to connect the printer through the mobile phones and simultaneously convenient to rapidly switch networks, the user is convenient to demand mobile printing and other mobile services, and the user is convenient to automatically switch the mobile phones to the network connected with the accessible internet when exiting the APP.
As an alternative embodiment, determining whether the network handover condition is satisfied includes: judging whether the access point currently connected with the terminal is an access point of the image forming device or not; if the access point to which the terminal is currently connected is an access point of the image forming apparatus, it is determined that the network switching condition is satisfied.
The specific judgment basis is that the target application program obtains the service set identifier of the currently connected access point, if the service set identifier comprises a character which accords with a preset letter, a number and a character, the service set identifier is indicated to be the network name of the access point of the image forming device, for example, the preset letter comprises direct, the preset character comprises direct connection and the brand name, and the preset number comprises the model of the image forming device.
Optionally, determining whether the network handover condition is satisfied includes: judging whether the access point connected before the terminal logs in the target application program is consistent with the access point connected currently; and if the access point connected before the terminal logs in the target application program is inconsistent with the access point connected currently, determining that the network switching condition is met.
As shown in fig. 1, if the terminal is connected to the access point 101 before the user logs in the target application, the printer 103 is connected after the user logs in the target application, and the access point 101 to which the terminal is connected is switched to the access point 105 of the printer 103, the access point before the user logs in the target application and the access point to which the user is currently connected are inconsistent; in another case, if the terminal connects to the access point 105 before the user logs in to the target application, communication is established with the printer 103 through the access point 105 after the target application is logged in, the access point to which the terminal is connected is unchanged, and it is determined that the access point to which the terminal is connected before the terminal logs in to the target application is consistent with the access point to which the terminal is currently connected.
Optionally, determining whether the network handover condition is satisfied includes: judging whether the target application program causes the terminal to perform network switching before exiting operation on the target application program; and if the target application program causes the terminal to perform network switching before exiting operation on the target application program, determining that the network switching condition is met.
Specifically, as shown in fig. 1, if the mobile phone 104 is connected to the access point 101 before the user logs in the target application, and the target application switches the access point 101 to which the mobile phone is connected to the access point 105 of the printer 103 in order to connect the target application to the printer 103 after logging in, the target application searches the printer 103 according to the mobile phone 104 being connected to the access point 105 and establishes communication with the printer 103, and the target application switches the mobile phone 104 from the connected access point 101 to the connected access point 105 in order to use the printer 103, which indicates that the target application causes the terminal to perform network switching, the target application may store a mark of network switching and different access points to which the mobile phone 104 is connected before and after network switching. Therefore, when the target application program is to be logged out, it is determined whether the target application program causes the terminal to perform network switching, that is, it may be determined whether the target application program stores a network switching flag, if the stored network switching flag indicates that the network switching condition is satisfied, or it is determined that the value of the network switching flag is the value of "1" indicating that the target application program causes the terminal to perform network switching before the target application program is logged out, and if "0" indicating that the target application program does not cause the terminal to perform network switching before the target application program is logged out.
Optionally, the controlling terminal disconnects the network connection with the access point to which it is currently connected, including: and deleting the service set identifier and the secret key of the currently connected access point stored in the operating system of the terminal.
Optionally, the controlling terminal disconnects the network connection with the access point to which it is currently connected, including: and sending a first instruction to an operating system of the terminal, wherein the first instruction is used for instructing the operating system of the terminal to reduce the connection priority of the access point connected currently. Optionally, after sending the first instruction to the operating system of the terminal, the method further includes: judging whether the operating system of the terminal reduces the connection priority of the access point currently connected or judges whether the terminal disconnects the access point currently connected with the terminal; if the operating system of the terminal does not lower the connection priority of the currently connected access point or the terminal does not disconnect the connection with its currently connected access point, the service set identifier and key of the currently connected access point stored in the operating system are deleted. The operating system of the terminal stores the service set identifier and the key of the access point to which the terminal is connected, and when deleting the service set identifier and the key of the currently connected access point stored in the operating system, the operating system reselects an access point to connect according to the access point recorded in the history in the operating system, and the access point may be the access point connected before entering the target application program.
The target application stores a service set identifier and a key of the currently connected access point and unique identification information of the connected image forming apparatus, and is used for enabling the terminal to establish communication with the access point stored by the target application and the search image forming apparatus when the user logs in the target application again. Specifically, when the user logs in the APP again, the APP will display a reminder screen to prompt the user whether the currently connected network is XXX, or not, the image forming device and the access point XXX which are connected last time need to be connected, if the user clicks "confirm" in the reminder screen, after entering the APP, the service set identifier and the key of the access point stored in the APP and the unique identification information of the image forming device are obtained, so that the terminal is connected to the access point stored in the APP and searches the image forming device to establish communication. According to the technical scheme provided by the embodiment of the invention, a user does not need to manually search the image forming device after entering the target application program, and the image forming device can be used by the APP quickly.
In the embodiment of the invention, the image forming device is not required to be searched manually when the target application program is logged in, and the terminal can be automatically connected with the image forming device connected with the target application program last time; after the target application program exits, the access point of the terminal connected with the image forming device can be automatically switched to the access point connected before the terminal enters the target application program, so that a user can conveniently and quickly and conveniently switch networks after exiting the target application program.
Example 2
As another alternative embodiment, before the exit operation is performed on the target application program, the method further includes: establishing a monitoring program of a target application program, wherein the monitoring program stores a service set identifier of a currently connected access point, a secret key and unique identification information of a currently connected image forming device; if the terminal is detected to log in the target application program again, the monitoring program sends stored information to the target application program.
At present, an APP of an image forming device is installed in an Android system or an IOS system of a mobile phone, and sometimes the situation that the APP is forced to exit or abnormally ends occurs, so that when the APP does not exit normally, the APP cannot record data in use, unique identification information of the image forming device connected with the APP, SSID and secret key of a corresponding access point are lost, and network switching processing which is executed when the APP exits normally cannot be executed is caused.
The present embodiment provides the following solution: the APP of the image forming device comprises a subsidiary APP and a main APP, wherein an object which can be operated by a user is the main APP, namely, the user performs printing, scanning, fax and other operations on the image forming device through the main APP. When the main APP is started, the auxiliary APP is started simultaneously; the auxiliary APP can always monitor the running condition of the main APP, and the auxiliary APP can execute part of the functions of the main APP, specifically, record the service set identifier and the secret key of the access point currently connected with the terminal before the main APP exits and the unique identification information of the image forming device connected with the main APP; if the main APP is forced to exit or abnormally ends, the auxiliary APP cannot be exited, after waiting for a preset time, if the auxiliary APP does not monitor the operation of the main APP or does not receive response information of the main APP, the auxiliary APP automatically exits again. When the main APP is restarted normally, the auxiliary APP and the main APP are started together, and the main APP acquires stored information from the auxiliary APP to perform network connection processing, specifically, the terminal is connected to a corresponding access point of the last-used image forming device; in addition, when the main APP is started, the stored information is acquired from the auxiliary APP, a reminding picture is displayed to prompt the user whether the currently connected network is XXX or not, if so, the user clicks 'confirm' in the reminding picture, and after entering the main APP, the terminal is connected to the stored access point and searches the image forming device to establish communication.
In addition, if the master APP is forced to exit or abnormally ends, the master APP is not as fast as the network switching process, and when the master APP is forced to exit or abnormally ends, the slave APP is not exited, waiting for a predetermined time (for example, 15 seconds), if the slave APP does not monitor the operation of the master APP or does not receive the response information of the master APP, performing the network switching operation of the first embodiment, that is, judging whether to perform the exit operation on the target application program (for example, the master APP); if the target application program is subjected to the exit operation, judging whether a network switching condition is met; and if the network switching condition is met, after the target application program performs the exit operation, the control terminal disconnects the network connection with the access point currently connected with the control terminal. The same points as in the first embodiment will not be described again.
If the main APP is normally withdrawn, the main APP and the auxiliary APP record the data in use, the unique identification information of the connected image forming device and the SSID and the secret key of the corresponding access point, and the main APP judges whether the network switching condition is met or not preferentially; if the network switching condition is met, the main APP control terminal disconnects the network connection with the access point currently connected with the main APP control terminal when the main APP exits the operation, and the auxiliary APP also exits along with the main APP during normal exiting. When the master APP is restarted, the master APP enables the terminal to be reconnected to the stored access point according to the unique identification information of the stored image forming device and the SSID and the secret key of the corresponding access point, and the master APP reestablishes communication with the stored image forming device.
By establishing the auxiliary APP, the normal operation and abnormal exit of the main APP are monitored, and when the main APP is abnormally ended, the main APP can be executed to perform network switching processing which is not performed until the main APP is forcedly exited or the connection between the terminal and an access point of the image forming device is not realized after the main APP is abnormally ended, so that a user still needs to manually switch the network of the terminal; by establishing the auxiliary APP, the information of the image forming device connected when the main APP is forced to exit or abnormally ends and the information of the corresponding access point are stored, so that the image forming device connected last time when the main APP is restarted is convenient.
Example 3
Fig. 3 is a flowchart of an alternative method for controlling network connection of a terminal according to an embodiment of the present invention, and the steps in fig. 3 are specifically described below:
step 201, judging whether to exit the APP; here, the exiting includes that the user causes the APP to exit under the operating system running environment of the mobile phone, and the user exits the APP to enter other application program interfaces, and the APP only runs in the background, and the APP is forced to exit or suddenly ends abnormally under the operating system running environment of the mobile phone, and also exits the APP.
Step 202, if the APP is exited, judging whether the network is required to be switched currently; three judging modes are available; firstly, judging whether the access point currently connected with the mobile phone is an access point used as a printer, and if so, entering step 203; the specific judgment basis is that the APP obtains the SSID of the access point connected currently, if the SSID comprises the characters conforming to the preset letters, numbers and characters, the SSID is the network name of the access point used as the printer, for example, the preset letters comprise direct, the preset characters comprise direct connection and brand names, and the preset numbers comprise the printer model; secondly, judging whether the access point connected with the mobile phone before entering the APP is consistent with the access point connected with the mobile phone currently, and if not, entering step 203; specifically, if after entering APP, the mobile phone connects to the access point 101, and when the user searches for and connects to the printer 103, and switches Wi-Fi connection of the mobile phone from the access point (access point 101) before entering APP to the access point 105 associated with the printer selected by the user, it indicates that the access point connected to the mobile phone before entering APP is inconsistent with the access point currently connected; in addition, it is possible that the user has previously set the Wi-Fi connection of the mobile phone to the access point 105, and after entering the APP, the APP selects to connect to the printer 103, so that the APP does not switch the Wi-Fi connection of the mobile phone, which means that the access point 105 is connected to the mobile phone before entering the APP, and the Wi-Fi connection of the mobile phone can directly communicate with the printer 103 after entering the APP, without switching the network, so that the access point currently connected to the mobile phone when exiting the APP is the access point 105, and then it is determined that the network is not to be switched, and step 205 is entered; thirdly, judging whether the APP enables the mobile phone to perform network switching, namely judging whether an access point connected with the mobile phone is changed for connecting to a printer after entering the APP, if so, entering step 203, otherwise, entering step 205.
Step 203, the APP enables the mobile phone to disconnect from an access point connected with the mobile phone currently; firstly, storing SSID and secret key of the currently connected access point by the APP so as to enable the mobile phone to be connected with the access point stored by the APP when the user logs in the APP again; the APP tries to send an instruction for reducing the connection priority of the currently connected access point to the operating system of the mobile phone, if the mobile phone fails to reduce or the connection with the currently connected access point is not disconnected after the instruction is sent, the APP deletes the SSID and the secret key of the currently connected access point stored in the operating system of the mobile phone; if the success is reduced or the mobile phone disconnects or deletes the access point connected with the mobile phone currently, the mobile phone is connected to the access point with higher priority instead of the access point connected with the mobile phone currently.
Step 204, the operating system of the mobile phone automatically selects an access point to establish Wi-Fi connection according to the access point connected before entering the login APP. The operating system of the mobile phone stores the SSID and the secret key of the access point connected by the mobile phone, and adjusts the connection priority of the access point with the newly established connection to the highest. When the mobile phone is disconnected with the currently connected access point, the mobile phone automatically connects with one access point according to the connected access point stored by the operating system.
Step 205, if it is determined that network switching is not needed, the mobile phone does not perform any network switching processing, and remains connected with the access point connected before exiting the APP, and ends.
In addition, in step 203, the user may also be prompted to ask whether the network switch is needed currently. If the user does not need to perform network switching, the mobile phone is not disconnected with the access point connected with the mobile phone currently, but the connection of the access point connected with the mobile phone before the APP is continuously kept after the APP is exited.
In addition, if the user confirms that the network is to be switched in step 203, an access point list may be displayed, so that the user selects an access point to which the mobile phone is connected after exiting the APP, and inputs a corresponding key, and in step 204, the mobile phone establishes communication with the access point according to the access point selected by the user.
According to the embodiment of the invention, the user does not need to manually operate too much network switching in the prior art, the printer connected by the APP last time can be automatically connected when the APP of the printer is used, the user does not need to manually search the printer, meanwhile, after the APP is withdrawn, wi-Fi of the mobile phone can be automatically switched from an access point of the connected printer to an access point connected before the APP is entered, and other operations are conveniently performed after the user withdraws from the APP.
