Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The invention provides a network switching system, which is used for: when the network of the mobile terminal is disconnected, the application program of the preset type running on the mobile terminal is switched to other networks in time.
FIG. 1 is a functional block diagram of an embodiment of a network switching system according to the present invention; as shown in fig. 1, the network switching system of the present invention includes a detection module 100 and a switching module 200, wherein the detection module 100 is used for detecting a network state of a mobile terminal in the network switching system, and the switching module 200 is used for switching a network used by the mobile terminal according to a detection result of the detection module 100 on the network where the mobile terminal is located.
Based on the network switching system illustrated in fig. 1, fig. 2 is a schematic workflow diagram of an embodiment of the network switching system of the present invention, and as shown in fig. 2, the workflow of the network switching system of the present invention may be implemented as steps S10-S40 described as follows:
step S10, the detecting module 100 detects the network signal strength of the first network currently used by the mobile terminal;
step S20, when the network signal strength of the currently used first network is smaller than a preset signal strength threshold, sending switching information to the switching module 200;
in the embodiment of the present invention, when the detection module 100 of the network switching system detects the network signal strength of the first network currently used by the mobile terminal, the detection frequency thereof may be set according to specific requirements; in a preferred embodiment, the detecting module 100 detects the network signal strength of the currently used network of the mobile terminal according to a first preset period value. For example, if the application running on the mobile terminal has a strong network dependency on the mobile terminal and has a high requirement on the network connectivity of the mobile terminal, the detection frequency of the detection module 100 may be set to be real-time detection or detection according to a high detection frequency. If the network dependency of the application running on the mobile terminal is not high, the detection module 100 may be configured to perform the detection of the network signal strength according to a lower detection frequency value. The embodiment of the present invention does not specifically limit the detection frequency value of the detection module 100 for detecting the network signal strength of the first network currently used by the mobile terminal.
In the embodiment of the present invention, when the detection module 100 detects that the network signal strength of the first network currently used by the mobile terminal is smaller than the preset signal strength threshold, the switching module 200 is sent with switching information for performing network switching, so that the switching module 200 switches the network currently used by the mobile terminal according to the switching information sent by the detection module 100.
In a preferred embodiment of the present invention, the switching information sent by the detecting module 100 includes: the network information and/or the network handover reason information corresponding to the second network facilitate the handover module 200 in the network handover system to handover the first network where the mobile terminal is currently located according to the handover information.
Step S30, the switching module 200 switches the first network used by the application program of the preset type running on the mobile terminal to the second network according to the switching information, and runs the application program of the preset type based on the second network; meanwhile, the detection module 100 continues to detect the network signal strength of the first network;
step S40, when the network signal strength of the first network is greater than or equal to the preset signal strength threshold, the switching module 200 switches the network used by the mobile terminal from the second network to the first network, and runs the application program of the preset type based on the first network.
In this embodiment of the present invention, the first network may be understood as: a home network corresponding to the mobile terminal; the second network may be understood as: the mobile terminal is attached to a network other than the home network. The switching module 200 receives the switching information sent by the detection module 100, analyzes the switching information, and switches the first network used by the application program of the preset type running on the mobile terminal to the second network according to the analysis result.
While the switching module 200 performs the network switching operation, the detection module 100 continues to detect the network signal strength of the first network corresponding to the mobile terminal. When the detection module 100 detects that the network signal strength of the first network is greater than or equal to the preset signal strength threshold, the switching module 200 switches the network used by the mobile terminal from the second network to the first network, and runs the application program of the preset type based on the first network.
In a preferred embodiment of the present invention, in order to improve stability of an operating network and reduce unnecessary handover frequency, when the detection module 100 detects that the network signal strength of the first network is greater than or equal to the preset signal strength threshold within a preset time period, the detection module sends information of network recovery to the handover module 200, so that the handover module 200 switches the second network used by the mobile terminal to the first network.
In a preferred embodiment of the present invention, the detecting module 100 detects that the network signal strength of the first network currently used by the mobile terminal is smaller than a preset signal strength threshold, and detects at least one second network signal, and sends the network identifier of the detected second network signal to the switching module 200; the switching module 200 accesses the second network according to the network identifier required for accessing the second network, thereby implementing switching of the first network used by the application program of the preset type running on the mobile terminal to the second network, and running the application program of the preset type based on the second network.
When the handover module 200 performs a network handover operation, the detection module 100 continues to detect the network signal strength of the first network corresponding to the mobile terminal. Because, in the embodiment of the present invention, the first network corresponding to the mobile terminal is a home network corresponding to the mobile terminal, and when the mobile terminal is in a moving state, a network signal of the mobile terminal itself may be flashed or no signal may occur, in this case, even if the switching module 200 switches the first network used by the mobile terminal to the second network, the detecting module 100 still performs the detection operation of the network signal strength of the corresponding first network. For example, in a specific application scenario, when a network of the mobile terminal has an emergency situation such as no network signal, accidental blocking or disconnection, or the mobile terminal moves based on the movement of the user, when the mobile terminal goes into or out of an elevator which may cause signal interruption or signal shielding, or crosses a base station, etc., a flash situation of the first network where the mobile terminal is located may be caused.
In the embodiment of the present invention, the preset type of application program may be understood as: the application program is sensitive to the network signal of the mobile terminal, that is, under the condition that the network of the mobile terminal is interrupted by flash, accidental blockage or other reasons, the application program of the type is affected badly or cannot be used normally, which brings unnecessary troubles (such as frequent login and the like) to the user; for example, an application program such as a TCP long-connection game, or an office application program with high network requirements, etc. Since the preset type of application programs may be different in different fields, different scenes, and different requirements, the preset type of application programs are not specifically limited in the embodiments of the present invention.
In a preferred embodiment of the present invention, when the handover module 200 performs the network handover operation, the following steps may be performed: the switching module 200 activates the execution file of the second network and activates the execution file of the first network, so that the network used by the mobile terminal can be switched from the second network back to the first network.
In a preferred embodiment of the present invention, when the detection module 100 detects that the network signal strength of the first network where the mobile terminal is currently located is less than the preset signal strength threshold (which may also be understood as during network disconnection of the mobile terminal), the switching module 200 may redirect the network request of the application program of the preset type on the mobile terminal to the virtual address corresponding to the mobile terminal, or utilize the 3G or 4G network corresponding to the mobile terminal home network operator, or suspend network communication temporarily and recover seamlessly when the network is normal, so that the client corresponding to the application program of the preset type does not sense the network disconnection of the mobile terminal, thereby improving user experience at the user side.
For the processing manner of redirection to the virtual address, in a preferred embodiment of the present invention, when the detection module 100 detects that the network signal strength of the first network currently used by the mobile terminal is smaller than a preset signal strength threshold, the switching module 200 redirects a network request corresponding to a preset type of application program running on the mobile terminal to the virtual address corresponding to the mobile terminal, and establishes a virtual network connection based on the virtual address, so that the mobile terminal implements data interaction with the server.
In a preferred embodiment of the present invention, when the detecting module 100 detects that the network signal strength of the wireless local area network currently used by the mobile terminal is smaller than the preset signal strength threshold, the switching module 200 switches the wireless local area network used by the mobile terminal to a 3G or 4G network corresponding to the mobile terminal home network operator.
For the processing mode of temporarily suspending network communication, in a preferred embodiment of the present invention, when the detection module 100 detects that the network signal strength of the first network currently used by the mobile terminal is smaller than a preset signal strength threshold, the switching module 200 switches the application program of the preset type running on the mobile terminal to the temporarily suspended state, and when the detection module 100 detects that the network signal strength of the first network is recovered, the switching module 200 switches the application program of the preset type from the temporarily suspended state to the normal running state, so as to implement seamless recovery.
The invention relates to a network switching system, which comprises a detection module and a switching module; detecting the network signal intensity of a first network currently used by the mobile terminal through a detection module; when the network signal intensity of the currently used first network is smaller than a preset signal intensity threshold value, sending switching information to a switching module; the switching module switches a first network used by an application program of a preset type running on the mobile terminal to a second network according to the switching information and runs the application program of the preset type based on the second network; meanwhile, the detection module continues to detect the network signal strength of the first network; when the network signal intensity of the first network is greater than or equal to the preset signal intensity threshold value, the switching module switches the network used by the mobile terminal from the second network to the first network, and runs the application program of the preset type based on the first network; the method and the device achieve the purpose of timely switching the application program of the preset type running on the mobile terminal to other networks when the network of the mobile terminal is disconnected, and improve the running stability of the application program on the mobile terminal.
In one embodiment, the network switching system further comprises a status record management module; the state recording management module records the running states of the application programs of the preset type according to a second preset period (for example, the value of the running state is short time such as 5 seconds and 10 seconds), and the recorded running states are sequentially arranged according to the running time sequence to form running state arrangement; when the switching module switches the application program of the preset type running on the mobile terminal to the temporary suspension state, the recording of the running state of the application program of the preset type is suspended according to a second preset period, and because the running state of the application program of the preset type does not progress when the application program is in the temporary suspension state, the recording is suspended, so that system resources can be saved, and unnecessary operation is avoided; when the switching module switches the application program of the preset type from the temporary suspension state to the normal operation state again, the operation state of the application program of the preset type is recorded again according to a second preset period, namely, when the application program is switched from the temporary suspension state to the normal operation state, the recording is restarted, so that the timely and accurate recording is realized, the operation state cannot be missed, and the recorded data is accurate;
the network switching system also comprises a flow use condition acquisition module; the traffic usage obtaining module obtains the current traffic usage of other running preset applications except the preset type of application when the detection module detects that the network signal strength of the first network currently used by the mobile terminal is smaller than a preset signal strength threshold, wherein the preset applications are applications with usage frequency exceeding preset frequency;
the network switching system also comprises an interface management module; the interface management module calls an interface of a preset application program with the minimum current flow usage amount when the switching module switches an application program of a preset type running on the mobile terminal to a temporary suspension state, and respectively displays the interface of the application program of the preset type and the interface of the preset application program with the minimum current flow usage amount in two display areas of a display screen of the mobile terminal; therefore, when the preset type application program is in the temporary suspension state, the system automatically displays the interface of the preset application program with the minimum current flow usage amount on the display screen, the blockage of the preset application program is less or not at all, so that a user can quickly and conveniently use the preset application program displayed at the same time when the preset type application program is in the temporary suspension state and the user cannot use the application program, the user cannot do nothing, and the use experience of the user is improved;
when the detection module detects that the network signal strength of the first network is recovered, the switching module switches the application program of the preset type from a temporary suspension state to a normal operation state, including:
when the detection module detects that the network signal intensity of the first network is recovered, the interface management module cancels the display of the interface of the preset application program with the minimum current flow usage; the switching module switches the application program of the preset type from a temporary suspension state to a preset historical operating state to continue to operate, wherein the preset historical operating state is the N1 last operating state in the latest operating state sequence recorded by the state record management module; wherein N1 can be 2, 3, etc.; however, the product of N1 and the second preset period should not be too large, for example, less than 30 seconds, so as to avoid that the process of repeated operation is too long due to too long time, the program execution process is prolonged, and system resources are wasted; in addition, the operation is not continued from the operation state corresponding to the suspension pause, but is continued from a preset historical operation state (which is earlier than the operation state corresponding to the suspension pause), so that the historical operation state familiar to the user is presented at the beginning stage of the continuous operation, the user can adapt to the continuous operation process of the application program of the preset type conveniently, and the application program of the preset type can be used more smoothly;
when the number of the running states in the recorded running state arrangement reaches N2, the state record management module deletes the first N2-N1 running states in the running state arrangement comprising N2 running states, wherein N2 is larger than N1, and the operation of regularly clearing records can save storage space; and the fact that N1 latest running states exist is always guaranteed, the normal acquisition of the preset historical running states is guaranteed, and the effective implementation of the scheme is guaranteed.
In another embodiment, because the effective range of the WIFI network signal radiation of the wireless router is generally small, if the mobile terminal moves out of the living room where the wireless router connected with the mobile terminal is located, the signal intensity of the WIFI network connected with the mobile terminal is usually weakened, and if a technical means is available, the mobile terminal can immediately switch the network when moving out of the living room, so that the switching effect can be improved, and the operation effect of the application program of the preset type can be further ensured. Therefore, two switching modes are designed, one is a fast switching mode, in the fast switching mode, if the mobile terminal is judged to move fast and move out of a room, the detection module can directly draw a conclusion that the network signal intensity of the currently used WIFI network is smaller than a preset signal intensity threshold value, and the mobile terminal is directly switched to the 4G network without waiting for judging that the network signal intensity of the currently used WIFI network is really smaller than the preset signal intensity threshold value to be switched to the 4G network (which is a common switching mode); when the mobile terminal is judged to be fast in moving speed but not to move out of a room, or the mobile terminal is judged to be slow in moving speed, a common switching mode is adopted; when the numerical value of the preset signal intensity threshold value meets certain characteristics, the situation that the mobile terminal moves faster and moves out of a room is solved, the situation that the mobile terminal moves faster and moves out of the room is more advanced by adopting the fast switching mode than the situation that the mobile terminal moves in the ordinary switching mode, so that the mobile terminal can be switched to the 4G network from the WIFI network in advance when the mobile terminal moves faster and moves out of the room, and the network effect is improved.
At this time, the first network is a WIFI network, and the second network is a 4G network;
the detection module and the switching module are arranged in the mobile terminal;
the mobile terminal is also provided with a speed sensor for acquiring the speed of the mobile terminal and an RFID electronic tag storing the mobile terminal identification;
the network switching system further includes:
the RFID electronic tag reader is arranged on a door frame of an exit door of a room where a wireless router generating the WIFI network is located;
the wireless router is in communication connection with the RFID electronic tag reader, and when the mobile terminal is connected with a WIFI network generated by the wireless router, the wireless router acquires the identifier of the mobile terminal and acquires the speed of the mobile terminal in real time;
when the network signal strength of the currently used WIFI network is less than a preset signal strength threshold, the detection module sends switching information to the switching module, which can be implemented as:
when the speed of the mobile terminal is lower than a preset speed (which indicates that the mobile terminal is slow in moving speed and the change of the WIFI network signal may be slow at the moment, and a common switching mode can be adopted), the wireless router sends a common switching mode enabling instruction to the detection module; the detection module detects the network signal intensity of the WIFI network currently used by the mobile terminal when receiving the common switching mode enabling instruction; judging the magnitude relation between the network signal intensity of the currently used WIFI network and a preset signal intensity threshold value; when the network signal intensity of the currently used WIFI network is smaller than a preset signal intensity threshold value, sending switching information to the switching module; the switching module switches a WIFI network used by an application program of a preset type running on the mobile terminal to a 4G network according to the switching information, and runs the application program of the preset type based on the 4G network; meanwhile, the detection module continues to detect the network signal strength of the WIFI network; continuing to judge the magnitude relation between the network signal intensity of the WIFI network and a preset signal intensity threshold value, when the network signal intensity of the WIFI network is greater than or equal to the preset signal intensity threshold value, switching the network used by the mobile terminal from the 4G network to the WIFI network by the switching module, and running the application program of the preset type based on the WIFI network;
wherein, the numerical value of the preset signal intensity threshold value meets the following characteristics: the signal strength of the WIFI signal smaller than that of the wireless router at the exit door.
