The output unit 150 may include a display unit 151, an audio output module 152, and the like.
The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI displaying a video or an image and related functions, and the like.

Based on the above mobile terminal hardware structure, various embodiments of the mobile terminal of the present invention are provided.
Referring to fig. 2, in a first embodiment of the mobile terminal of the present invention, the mobile terminal includes:
an obtaining module 10, configured to obtain other network access points in a current network environment when obtaining a target network resource based on a currently connected network access point fails;
a determining module 20, configured to determine a network access point suitable for acquiring a target network resource from other network access points;
the connection module 30 is configured to disconnect the currently connected network access point and establish a connection with the determined network access point to acquire the target network resource.
With the popularization of mobile terminals such as mobile phones and the like in the life of people, people can access the internet through various mobile terminals so as to acquire information, transact business and the like, and great convenience is brought to the life of people. Generally, a user may connect a network access point such as a bluetooth hotspot and a Wi-Fi hotspot through a mobile terminal of the user, so as to obtain a network access service provided by an operator to which the connected network access point belongs, and further obtain a network resource, such as a picture or text message on a certain website accessed by using a browser. Now, considering the following scenario, due to the reason of the control policy of the network access point or the problem of interconnection and intercommunication between the operators to which the network access point belongs, the network resources accessed by the user cannot be correctly loaded, or part of picture external links used in the web page cannot be correctly loaded, which causes unsmooth information acquisition for the user. At this time, the user needs to manually switch the mobile terminal to access to other network access points to acquire the network resources, for example, when a certain website is accessed by using a connected network, the access is slow, the resource loading is unsuccessful, and the user needs to manually switch to the telecommunication network to reload the resources. However, for a common user, the user does not know what reason causes the network resource loading failure, and does not actively switch the network access point connected to the mobile terminal, which causes great inconvenience for the user.
In view of this, the present invention provides a network switching scheme, which ensures that a mobile terminal can acquire a network resource desired by a user and then present the network resource to the user. Specifically, in this embodiment, when the target network resource is failed to be acquired based on the currently connected network access point, the acquiring module 10 scans the current network environment to acquire other network access points in the current network environment.
After scanning other network access points of the current network environment, the acquisition module 10 transmits access point information of the scanned other network access points to the determination module 20.
After receiving the access point information of the other network access points transmitted by the obtaining module 10, the determining module 20 determines, according to the received node information, a network access point suitable for obtaining the target network resource from the other network access points. The access point information at least comprises operator information and network speed information.
Optionally, in this embodiment, when determining the network access point suitable for acquiring the target network resource, the determining module 20 determines, as the network access point suitable for acquiring the target network resource, a network access point belonging to an operator of a server where the target network resource is located, among the other network access points scanned by the acquiring module 10;
or, when determining the network access point suitable for acquiring the target network resource, the determining module 20 determines, as the network access point suitable for acquiring the target network resource, a network access point belonging to a different operator from the currently connected network access point among the other network access points scanned by the acquiring module 10.
When it is determined that there is a network access point suitable for acquiring the target network resource among the other network access points, the determining module 20 transmits the node identifier of the determined network access point to the connection module 30, so that the connection module 30 performs handover of the network access point. The node Identifier is used to uniquely identify the network Access point, for example, when the network Access point is a Wi-Fi hotspot, the node Identifier includes an SSID (Service Set Identifier), a MAC (Media Access Control) address, and the like, and optionally, the node Identifier may further be combined with the SSID and the MAC address as the node Identifier, an index is established according to the SSID, and then a specific Wi-Fi hotspot is determined according to the MAC address.
When receiving the node identifier transmitted by the determining module 20, the connecting module 30 determines the network access point which needs to be switched to connect currently, and first disconnects the network access point which is connected currently, and then establishes the connection of the network access point to be switched corresponding to the node identifier, so as to obtain the target network resource desired by the user.
With combined reference to fig. 3 and 4, the mobile terminal automatically disconnects the connection with the "mobile" network access point and establishes a connection with a "telecommunications" network access point adapted to acquire the target network resource, when the connection-based "mobile" network access point fails to acquire the target network resource.
Further, in this embodiment, when it is determined that there are a plurality of network access points suitable for acquiring the target network resource among the other network access points, the determining module 20 further determines a network access point with the highest network speed among the suitable network access points as a network access point to be switched, so as to acquire the target network resource more smoothly. For example, the mobile terminal is currently connected to a "mobile" network access point, and there are a "telecommunication" network access point, a "connected" network access point, and a "radio and television" network access point in the current network environment, and the network speed of the "telecommunication" network access point is 24Mbps, the network speed of the "connected" network access point is 14Mbps, and the network speed of the "radio and television" network access point is 8Mbps, then the mobile terminal connects the "telecommunication" network access point as a network access point to be switched.
Optionally, to improve the security of network access, in this embodiment, the mobile terminal further includes a setting module (not shown in fig. 2) configured to set an access point with a preset access rule for a predetermined network resource;
the determining module 20 is further configured to determine whether the target network resource is a predetermined network resource; and the access point is also used for determining that the access point with the preset access rule is a network access point suitable for acquiring the target network resource when the judgment result is yes.
Specifically, after receiving the access point information of the scanned network access point transmitted by the obtaining module 10, the determining module 20 does not perform the above-described operation of determining a suitable network access point, but determines whether the target network resource is a predetermined network resource, and if so, directly determines the access point of the preset access rule set by the setting module as the network access point suitable for obtaining the target network resource; if not, the above-described determination of appropriate network access point operation is performed. The setting module may set an access point with a preset access rule for a predetermined network resource according to a user operation, for example, the user may set a network access point of a company internal network as the access point with the preset access rule for a target network resource "company office website".
The mobile terminal provided in this embodiment, by detecting the working state of the connected network access point, when the target network resource cannot be obtained through the currently connected network access point, automatically switches to the network access point suitable for obtaining the target network resource, so as to obtain the target network resource. Compared with the prior art, the method and the device have the advantages that the user does not need to manually switch the network access point, but automatically switches to the unobstructed network access point, and the internet access quality of the mobile terminal is ensured.
Further, based on the first embodiment, a second embodiment of the mobile terminal of the present invention is provided, which is different from the first embodiment in that a verification module is added in the embodiment, and is configured to verify a currently connected network access point based on other network access points when an acquisition request of a target network resource is detected, so as to acquire the target network resource based on the currently connected network access point when the verification is successful.
It can be understood that, in practical use, the network environment is dangerous and complex, and there is a risk that the network is hijacked, and when the network is hijacked, the network access will be navigated to the wrong site, causing property loss, information leakage and the like of the user. In view of this, to avoid network hijacking, the present embodiment adds an authentication operation on the basis of the first embodiment. Only the foregoing differences will be described below, and other differences can refer to the foregoing first embodiment, which is not described herein again.
In this embodiment, the mobile terminal further includes an authentication module, configured to authenticate a currently connected network access point to prevent unauthorized hijacking. Specifically, when the acquisition request of the target network resource is detected, the verification module verifies the currently connected network access point based on other network access points in the current network environment. The acquisition request of the target network resource is triggered in response to user operation, for example, when a user clicks a hyperlink which is displayed on a screen of the touch mobile terminal and leads to a certain webpage, the acquisition request of the corresponding acquisition of the webpage network resource is triggered.
When the currently connected network access point is verified, the verification module analyzes the domain name of the target network resource based on the domain name resolution servers corresponding to other network access points and the currently connected network access point respectively, wherein when the resolution results are consistent, the verification is passed.
As will be appreciated by those skilled in the art, the role of the domain name resolution server is to map domain names to IP addresses that can be recognized by the real terminals, so that the terminals can communicate further, deliver web addresses and content, etc. When the network is hijacked, the domain name resolution request in the hijacked range is intercepted, illegal molecules pass through the domain name of the analysis request and release the resolution request outside the examination range, and for the resolution request in the examination range, false IP addresses are returned or nothing is done so that the resolution request loses response, and the effect is that false websites which cannot react or access a specific network cause user loss.
Therefore, in this embodiment, the verification module analyzes the domain name of the target network resource based on the domain name resolution servers corresponding to the network access points in the current network environment, and if the resolution results returned by the domain name resolution servers are consistent, the verification is passed, it is determined that the currently connected network access point is not hijacked, and the target network resource can be acquired based on the currently connected network access point. For example, when the domain name of hundred degrees is currently accessed, and the resolution results returned by each resolution server including the currently connected network access point are "202.108.22.5", the authentication on the currently connected network access point is passed.
In addition, when inconsistent analysis results exist in the analysis results returned by the domain name analysis servers, the verification fails, and at the moment, the verification module outputs prompt information to prompt a user that the current network is hijacked, so that the risk of property loss and information leakage exists. For example, the prompt message output by the verification module is "the current network is hijacked, please pay attention to property security".
Optionally, in this embodiment, the verification module is further configured to identify a domain name of the target network resource, and perform a verification operation on the currently connected network access point only when the domain name of the target network resource is a preset domain name. The preset domain name can be set by a user according to actual needs, and can also be set by a default of the mobile terminal. For example, the user may set it as the domain name of a financial-type website, thereby securing the user's funds and information.
Further, based on the foregoing first or second embodiment, a third embodiment of the mobile terminal of the present invention is proposed, which is different from the foregoing embodiment in that in this embodiment, the determining module 20 is further configured to determine, when the network is idle, whether a target network access point with a higher network speed than a currently connected network access point exists in other network access points;
the connection module 30 is further configured to disconnect the currently connected network access point and establish a connection with the target network access point when the target network access point exists.
It should be noted that, in practical use, as shown in fig. 5, when a user holds a mobile terminal in a network environment with multiple network access points, since the user cannot identify which network access point provides more smooth network access service, the user can manually switch to another network access point to try only when the user feels that the access speed of the network access service provided by the current network access point is fast. In order to further improve the internet access quality of the mobile terminal, the embodiment further adds the network access point switching operation based on the internet speed on the basis of the foregoing embodiment. Only the differences will be described below, and other descriptions related to the foregoing embodiments may be referred to, and are not repeated herein.
In this embodiment, the determining module 20 detects the network status in real time, and determines whether a target network access point with a higher network speed than the currently connected network access point exists in other network access points when the network is idle, and when the target network access point with a higher network speed than the currently connected network access point exists, the determining module 20 transmits the node identifier of the target network access point to the connecting module 30. The network idle includes that no network transmission operation is detected within a preset time period, the preset time period may be set by a user, or may be set by a default of the mobile terminal, for example, the default of the preset time period is set to 5 minutes, that is, when no network transmission operation is detected within 5 minutes, the determining module 20 determines that the mobile terminal is currently in an idle state.
When receiving the node identifier transmitted by the determining module 20, the connecting module 30 determines the network access point to which connection needs to be switched currently, and first disconnects the connection with the currently connected network access point, and then establishes the connection with the target network access point corresponding to the node identifier, so as to ensure that the mobile terminal can provide good internet access quality to the user at any time.
Further, the present invention also provides a network handover method, which corresponds to the first embodiment of the mobile terminal of the present invention with reference to fig. 2 and fig. 6, and in the first embodiment of the network handover method of the present invention, the network handover method includes:
step S10, when the target network resource is failed to be obtained based on the currently connected network access point, other network access points of the current network environment are obtained;
step S20, determining the network access point suitable for obtaining the target network resource in other network access points;
and step S30, disconnecting the currently connected network access point and establishing the connection with the determined network access point to acquire the target network resource.
With the popularization of mobile terminals such as mobile phones and the like in the life of people, people can access the internet through various mobile terminals so as to acquire information, transact business and the like, and great convenience is brought to the life of people. Generally, a user may connect a network access point such as a bluetooth hotspot and a Wi-Fi hotspot through a mobile terminal of the user, so as to obtain a network access service provided by an operator to which the connected network access point belongs, and further obtain a network resource, such as a picture or text message on a certain website accessed by using a browser. Now, considering the following scenario, due to the reason of the control policy of the network access point or the problem of interconnection and intercommunication between the operators to which the network access point belongs, the network resources accessed by the user cannot be correctly loaded, or part of picture external links used in the web page cannot be correctly loaded, which causes unsmooth information acquisition for the user. At this time, the user needs to manually switch the mobile terminal to access to other network access points to acquire the network resources, for example, when a certain website is accessed by using a connected network, the access is slow, the resource loading is unsuccessful, and the user needs to manually switch to the telecommunication network to reload the resources. However, for a common user, the user does not know what reason causes the network resource loading failure, and does not actively switch the network access point connected to the mobile terminal, which causes great inconvenience for the user.
In view of this, the present invention provides a network switching scheme, which ensures that a mobile terminal can acquire a network resource desired by a user and then present the network resource to the user. Specifically, in this embodiment, when the target network resource is failed to be acquired based on the currently connected network access point, the acquiring module 10 scans the current network environment to acquire other network access points in the current network environment.
After scanning other network access points of the current network environment, the acquisition module 10 transmits access point information of the scanned other network access points to the determination module 20.
After receiving the access point information of the other network access points transmitted by the obtaining module 10, the determining module 20 determines, according to the received node information, a network access point suitable for obtaining the target network resource from the other network access points. The access point information at least comprises operator information and network speed information.
Optionally, in this embodiment, when determining the network access point suitable for acquiring the target network resource, the determining module 20 determines, as the network access point suitable for acquiring the target network resource, a network access point belonging to an operator of a server where the target network resource is located, among the other network access points scanned by the acquiring module 10;
or, when determining the network access point suitable for acquiring the target network resource, the determining module 20 determines, as the network access point suitable for acquiring the target network resource, a network access point belonging to a different operator from the currently connected network access point among the other network access points scanned by the acquiring module 10.
When it is determined that there is a network access point suitable for acquiring the target network resource among the other network access points, the determining module 20 transmits the node identifier of the determined network access point to the connection module 30, so that the connection module 30 performs handover of the network access point. The node Identifier is used to uniquely identify the network Access point, for example, when the network Access point is a Wi-Fi hotspot, the node Identifier includes an SSID (Service Set Identifier), a MAC (Media Access Control) address, and the like, and optionally, the node Identifier may further be combined with the SSID and the MAC address as the node Identifier, an index is established according to the SSID, and then a specific Wi-Fi hotspot is determined according to the MAC address.
When receiving the node identifier transmitted by the determining module 20, the connecting module 30 determines the network access point which needs to be switched to connect currently, and first disconnects the network access point which is connected currently, and then establishes the connection of the network access point to be switched corresponding to the node identifier, so as to obtain the target network resource desired by the user.
With combined reference to fig. 3 and 4, the mobile terminal automatically disconnects the connection with the "mobile" network access point and establishes a connection with a "telecommunications" network access point adapted to acquire the target network resource, when the connection-based "mobile" network access point fails to acquire the target network resource.
Further, in this embodiment, when it is determined that there are a plurality of network access points suitable for acquiring the target network resource among the other network access points, the determining module 20 further determines a network access point with the highest network speed among the suitable network access points as a network access point to be switched, so as to acquire the target network resource more smoothly. For example, the mobile terminal is currently connected to a "mobile" network access point, and there are a "telecommunication" network access point, a "connected" network access point, and a "radio and television" network access point in the current network environment, and the network speed of the "telecommunication" network access point is 24Mbps, the network speed of the "connected" network access point is 14Mbps, and the network speed of the "radio and television" network access point is 8Mbps, then the mobile terminal connects the "telecommunication" network access point as a network access point to be switched.
Optionally, to improve the security of the network access, in this embodiment, before step S20, the method further includes:
setting an access point with preset access rules aiming at predetermined network resources;
step S20 includes:
judging whether the target network resource is a preset network resource;
and if so, determining that the access point with the preset access rule is a network access point suitable for acquiring the target network resource.
Correspondingly, the mobile terminal further includes a setting module (not shown in fig. 2) for setting an access point with a preset access rule for a predetermined network resource;
the determining module 20 is further configured to determine whether the target network resource is a predetermined network resource; and the access point is also used for determining that the access point with the preset access rule is a network access point suitable for acquiring the target network resource when the judgment result is yes.
Specifically, after receiving the access point information of the scanned network access point transmitted by the obtaining module 10, the determining module 20 does not perform the above-described operation of determining a suitable network access point, but determines whether the target network resource is a predetermined network resource, and if so, directly determines the access point of the preset access rule set by the setting module as the network access point suitable for obtaining the target network resource; if not, the above-described determination of appropriate network access point operation is performed. The setting module may set an access point with a preset access rule for a predetermined network resource according to a user operation, for example, the user may set a network access point of a company internal network as the access point with the preset access rule for a target network resource "company office website".
In the network switching method provided in this embodiment, by detecting the working state of the connected network access point, when the target network resource cannot be obtained through the currently connected network access point, the network access point suitable for obtaining the target network resource is automatically switched to, so as to obtain the target network resource. Compared with the prior art, the method and the device have the advantages that the user does not need to manually switch the network access point, but automatically switches to the unobstructed network access point, and the internet access quality of the mobile terminal is ensured.
Further, based on the first embodiment, a second embodiment of the network handover method of the present invention is provided, which corresponds to the second embodiment of the foregoing mobile terminal, and is different from the first embodiment in that the present embodiment adds an authentication operation of a network access point, and specifically, before step S10, the method further includes:
when the acquisition request of the target network resource is detected, the currently connected network access point is verified based on other network access points, and when the verification is successful, the target network resource is acquired based on the currently connected network access point.
It can be understood that, in practical use, the network environment is dangerous and complex, and there is a risk that the network is hijacked, and when the network is hijacked, the network access will be navigated to the wrong site, causing property loss, information leakage and the like of the user. In view of this, to avoid network hijacking, the present embodiment adds an authentication operation on the basis of the first embodiment. Only the foregoing differences will be described below, and other differences can refer to the foregoing first embodiment, which is not described herein again.
In this embodiment, the mobile terminal further includes an authentication module, configured to authenticate a currently connected network access point to prevent unauthorized hijacking. Specifically, when the acquisition request of the target network resource is detected, the verification module verifies the currently connected network access point based on other network access points in the current network environment. The acquisition request of the target network resource is triggered in response to user operation, for example, when a user clicks a hyperlink which is displayed on a screen of the touch mobile terminal and leads to a certain webpage, the acquisition request of the corresponding acquisition of the webpage network resource is triggered.
Further, in this embodiment, the step of authenticating the currently connected network access point based on the other network access point includes:
and resolving the domain name of the target network resource based on domain name resolution servers corresponding to other network access points and the currently connected network access point respectively, wherein when the resolution results are consistent, the verification is passed.
When the currently connected network access point is verified, the verification module analyzes the domain name of the target network resource based on the domain name resolution servers corresponding to other network access points and the currently connected network access point respectively, wherein when the resolution results are consistent, the verification is passed.
As will be appreciated by those skilled in the art, the role of the domain name resolution server is to map domain names to IP addresses that can be recognized by the real terminals, so that the terminals can communicate further, deliver web addresses and content, etc. When the network is hijacked, the domain name resolution request in the hijacked range is intercepted, illegal molecules pass through the domain name of the analysis request and release the resolution request outside the examination range, and for the resolution request in the examination range, false IP addresses are returned or nothing is done so that the resolution request loses response, and the effect is that false websites which cannot react or access a specific network cause user loss.
Therefore, in this embodiment, the verification module analyzes the domain name of the target network resource based on the domain name resolution servers corresponding to the network access points in the current network environment, and if the resolution results returned by the domain name resolution servers are consistent, the verification is passed, it is determined that the currently connected network access point is not hijacked, and the target network resource can be acquired based on the currently connected network access point. For example, when the domain name of hundred degrees is currently accessed, and the resolution results returned by each resolution server including the currently connected network access point are "202.108.22.5", the authentication on the currently connected network access point is passed.
In addition, when there is an inconsistent resolution result in the resolution result returned by each domain name resolution server, the authentication fails, and after the step of authenticating the currently connected network access point based on the other network access points, the method further includes:
and when the verification fails, outputting prompt information.
When the verification fails, the verification module outputs prompt information to prompt a user that the current network is hijacked, and the risk of property loss and information leakage exists. For example, the prompt message output by the verification module is "the current network is hijacked, please pay attention to property security".
Optionally, in this embodiment, the verification module is further configured to identify a domain name of the target network resource, and perform a verification operation on the currently connected network access point only when the domain name of the target network resource is a preset domain name. The preset domain name can be set by a user according to actual needs, and can also be set by a default of the mobile terminal. For example, the user may set it as the domain name of a financial-type website, thereby securing the user's funds and information.
Further, based on the foregoing first or second embodiment, a third embodiment of the network handover method of the present invention is proposed, which corresponds to the foregoing third embodiment of the mobile terminal, and in this embodiment, the network handover method further includes the following steps:
when the network is idle, determining whether a target network access point with the network speed higher than that of the currently connected network access point exists in other network access points;
if so, disconnecting the network access point currently connected with the network access point and establishing the connection with the target network access point.
It should be noted that, in practical use, as shown in fig. 5, when a user holds a mobile terminal in a network environment with multiple network access points, since the user cannot identify which network access point provides more smooth network access service, the user can manually switch to another network access point to try only when the user feels that the access speed of the network access service provided by the current network access point is fast. In order to further improve the internet access quality of the mobile terminal, the embodiment further adds the network access point switching operation based on the internet speed on the basis of the foregoing embodiment. Only the differences will be described below, and other descriptions related to the foregoing embodiments may be referred to, and are not repeated herein.
In this embodiment, the determining module 20 detects the network status in real time, and determines whether a target network access point with a higher network speed than the currently connected network access point exists in other network access points when the network is idle, and when the target network access point with a higher network speed than the currently connected network access point exists, the determining module 20 transmits the node identifier of the target network access point to the connecting module 30. The network idle includes that no network transmission operation is detected within a preset time period, the preset time period may be set by a user, or may be set by a default of the mobile terminal, for example, the default of the preset time period is set to 5 minutes, that is, when no network transmission operation is detected within 5 minutes, the determining module 20 determines that the mobile terminal is currently in an idle state.
When receiving the node identifier transmitted by the determining module 20, the connecting module 30 determines the network access point to which connection needs to be switched currently, and first disconnects the connection with the currently connected network access point, and then establishes the connection with the target network access point corresponding to the node identifier, so as to ensure that the mobile terminal can provide good internet access quality to the user at any time.
