Another method is to try to search for a cell by a background network searching mechanism of the terminal itself, so as to recover to a high-standard network, however, the method usually limits the number of times of network searching due to a gradient interval mechanism, so that after the terminal fails to try to search for a network for many times in a weak signal area, if the terminal moves to an area with better signal coverage, network searching may not be triggered in time, and the terminal stays in a low-standard network for a long time, thereby affecting the user internet surfing experience.

In the method, if a network accessed by the terminal is switched from a high-system network to a low-system network, when the condition that the terminal is switched from a screen-off state to a screen-on state is detected, high-system network searching can be triggered, namely, a network with a communication system higher than a second communication system is searched. The terminal is switched from the screen-off state to the screen-on state, which usually indicates that a user may be switched from the state of not using the terminal for a long time to the state of using the terminal, so that under the condition that the terminal is not screen-on, network recovery is not actively performed, energy consumption is saved, and under the condition that the terminal is switched from the screen-off state to the screen-on state, network searching can be immediately triggered, so that the influence on the user internet surfing experience caused by the fact that the terminal stays in a low-standard network for a long time is avoided.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 1 illustrates a method for network recovery provided by an embodiment of the present application, which may be applied to a terminal.
S101, determining that a network accessed by a terminal is switched from a network of a first communication system to a network of a second communication system, wherein the first communication system is higher than the second communication system.
In this step, the terminal may determine whether the network accessed by the terminal is switched from the network of the high communication system to the network of the low communication system, for example, from the network of the first communication system to the network of the second communication system, by detecting the network currently accessed by the terminal.
Among them, a high communication system (hereinafter, simply referred to as a high system) and a low communication system (hereinafter, simply referred to as a low system) may be opposite. For example, when a third generation (3rd generation, 3g) network functions as a high communication system network, a second generation (2nd generation, 2g) network may function as a low system network; for another example, when the 3G network is a low-system network, the fourth generation (4 th generation, 4G) and the fifth generation (5th generation, 5g) networks can be high-system networks.
For example, if the terminal detects that the accessed network is switched from the 5G network to the 4G/3G/2G network, or switched from the 4G network to the 3G/2G network, or switched from the 3G network to the 2G network, it may be determined that the network accessed by the terminal is switched from the high-standard network to the low-standard network.
S102, under the condition that the screen state of the terminal is detected to be switched from the screen-off state to the screen-on state, searching for a network with the communication system higher than the second communication system.
Under the condition that a network accessed by the terminal is switched from a network of a first communication system to a network of a second communication system, the terminal can detect the current screen state, and if the screen state is switched from a screen-off state to a screen-on state, high-system network searching can be triggered, namely, a network with a communication system higher than the second communication system is searched.
As an example, the network of the first communication system is a 5G network, the network of the second communication system is a 4G network, and at this time, when the network accessed by the terminal is switched from the 5G network to the 4G network, if the terminal detects that the current screen state is switched from the screen-off state to the screen-on state, the network of the communication system higher than 4G, such as the 5G network, can be searched;
as another example, the network of the first communication system is a 4G network, the network of the second communication system is a 3G network, and at this time, when the network accessed by the terminal is switched from the 4G network to the 3G network, if the terminal detects that the screen state is switched from the off-screen state to the on-screen state, a network with a communication system higher than 3G, such as a 4G/5G network, may be searched. In the scenario, under a possible condition, if the highest available communication system of the terminal is 4G, the terminal can search for a 4G network when performing high-system network searching; in another possible case, if the highest available communication system of the terminal is 5G, the terminal may preferentially search for a 5G network when performing high-system network search, and if the search fails, search for a 4G network.
According to the method of the embodiment, if the network accessed by the terminal is switched from the high-standard network to the low-standard network, when the terminal is detected to be switched from the screen-off state to the screen-on state, the high-standard network search can be triggered, that is, the network with the communication standard higher than the second communication standard is searched. The terminal is switched from the non-bright screen to the bright screen, which generally indicates that a user may be switched from a state of not using the terminal to a state of using the terminal for a long time, so that network recovery is not actively performed under the condition that the terminal is not bright, energy consumption is saved, network searching can be immediately triggered under the condition that the terminal is switched from the non-bright screen to the bright screen, and the influence on the user internet surfing experience caused by the fact that the terminal resides in a low-standard network for a long time is avoided.
In some possible scenarios, after the terminal is switched from the high-standard network to the low-standard network, the terminal is not restored to the high-standard network for a long time, which indicates that the terminal is located in an area where the signal is weak (e.g., the terminal is placed in a drawer). At this time, if the screen state of the terminal is switched from the screen-off state to the screen-on state, it indicates that the user may start using the terminal, that is, the position of the terminal may have changed (for example, taken out from a drawer), and therefore, the network searching may be triggered immediately under the condition that the terminal is switched from the screen-off state to the screen-on state, which is beneficial to increasing the success rate of high-format network searching, and further improving the user experience.
In some embodiments, the method further comprises: determining a first time length lasting when the terminal is accessed to a network of a second communication system; and detecting the screen state of the terminal under the condition that the first duration is greater than or equal to a first preset duration.
The first duration may also be understood as a duration that the terminal lasts after being switched from the network of the first communication system to the network of the second communication system, or may also be understood as a duration that the terminal resides in the network of the second communication system after being switched from the network of the first communication system to the network of the second communication system. For example, assuming that the time when the terminal determines that the accessed network is switched from the network of the first communication system to the network of the second communication system is the first time, the first time duration may be understood as a time duration lasting with the first time as a timing starting point.
In this embodiment, the terminal may detect the current screen state when the first duration is greater than or equal to the first preset duration, and further may determine whether the screen state of the terminal is switched from the screen-off state to the screen-on state. In other words, after the terminal accesses the network of the second communication system, the terminal needs to wait for a period of time (a first preset time period) and then perform the screen state detection.
In one possible case, the first time duration is less than a first predetermined time duration. In this case, it is indicated that the terminal may have been automatically restored to the high-standard network within the first preset duration, for example, the terminal has been restored to the high-standard network through the existing background network searching mechanism, and then the terminal may not need to perform screen state detection, which is beneficial to saving system power consumption.
In another possible scenario, the first duration is greater than or equal to a first preset duration. In this case, it indicates that the terminal has not recovered to the high-standard network within the first preset time, and then the terminal may determine whether to trigger the high-standard network search according to the change condition of the screen state, thereby avoiding that the user experience of surfing the internet is affected because the terminal resides in the low-standard network for a long time.
It should be understood that the first duration may be a pre-configured fixed duration or may be a dynamically configured duration. The first time period may be stored in the terminal in advance, or may be sent to the terminal by other devices through a data transmission manner, which is not limited in the present application. In a specific example, the first duration may default to 60 seconds, for example.
In some embodiments, in the case of detecting that the screen state of the terminal is changed from the off-screen state to the on-screen state, searching for a network having a communication system higher than the second communication system includes: under the condition that the screen state of the terminal is detected to be changed from the screen-off state to the screen-on state, judging whether a network accessed by the terminal is a network of a second standard or not; and if the network accessed by the terminal is the network of the second system, searching the network of which the communication system is higher than the second communication system.
That is to say, when the terminal detects that the screen state is changed from the screen-off state to the screen-on state, the terminal can detect the currently accessed network again, and further judge whether the network accessed by the terminal is still the network of the second standard.
In a possible case, if the network to which the terminal currently accesses is still the network of the second standard, that is, the terminal still resides in the low-standard network, the terminal may trigger the high-standard network search to search for a network with a communication standard higher than the second communication standard. In another possible situation, if the network to which the terminal is currently accessed is not the network of the second communication system, it indicates that the terminal may have recovered to the high-system network, and at this time, the terminal may not need to perform a subsequent high-system network search process.
In some embodiments, searching for a network having a communication standard higher than the second communication standard includes: and under the condition that the terminal does not execute the first operation, searching for a network with a communication system higher than the second communication system. That is, if the terminal is executing the first operation, the high-system network searching is not performed, so as to avoid the transmission conflict between the operation of the high-system network searching and the first operation currently executed by the user.
Illustratively, the first operation may include, for example, at least one of: turning on or off flight mode, plugging in or out Subscriber Identity Module (SIM), talking, and searching network.
The first possible case, the first operation is the opening or closing of the flight model, in which case the first operation is being performed, and can also be understood as the action of opening or closing the flight mode being performed. In some embodiments, the time from the act of triggering the on or off flight mode to a short time (e.g., within 5 seconds) after the act is completed may also be considered to be the time that the terminal is performing the first operation. For example, if the first operation is closing the flight model, then the time period from the time when the terminal is no signal to the time when the signal returns to normal, which is generally 5 seconds from the time when the action of triggering the closing of the flight mode is started, may also be considered as the time when the terminal is performing the first operation.
In a second possible case, the first operation is plugging and unplugging the SIM card, in which case the first operation is being performed, and it can also be understood that an action of plugging and unplugging the SIM card is being performed. In some embodiments, the time from the triggering of the action of plugging the SIM card to the end of the action (e.g. within 5 seconds) may also be considered as the time when the first operation is being performed. For example, if the first operation is inserting a SIM card, the time from triggering the action of inserting the SIM card to a short time after the action is completed may also be considered as the time when the terminal is performing the first operation.
In a third possible scenario, the first operation is a call, in which case the method further comprises: under the condition that the terminal executes the call, detecting whether the call is executed completely; and after the call execution is finished, searching for a network with a communication system higher than the second communication system. That is, before triggering the high-system network search, if the terminal enters the call state, the high-system network search may be triggered after the call state is ended.
In a fourth possible scenario, the first operation is to search for a network (e.g., to search for a high-standard network). That is, in the case where the terminal is performing network search, the terminal may not need to perform high-system network search based on the change situation of the screen state.
In some embodiments, the method further comprises: and determining the searching priority of the network of a plurality of communication modes which can be used by the terminal. At this time, the method for searching for a network having a communication system higher than the second communication system may be, for example: and searching the network with the communication system higher than the second communication system according to the searching priority.
For example, the terminal may determine the search priority for at least one network based on the network of the at least one communication system that the terminal may use. The network of at least one communication system that the terminal can use may also be understood as a network of at least one communication system that the terminal supports. The search priority can also be understood as the sequence of the search. For example, the search priority includes a first priority and a second priority, where the first priority is higher than the second priority, and then, in the process of searching for a network higher than the second communication system, the terminal may preferentially search for a network corresponding to the first priority and then search for a network corresponding to the second priority (the communication system of the network corresponding to the second priority is higher than the second communication system). That is, the search order for a network corresponding to a high priority (e.g., a first priority) precedes the search order for a network corresponding to a low priority (e.g., a second priority).
In some embodiments, the searching priority for performing the high-standard network searching may be determined according to the level of the network communication standard. For example, a network with a higher communication system may be assigned a higher search priority, and a network with a lower communication system may be assigned a lower search priority.
Illustratively, it is assumed that the network of at least one communication system usable by the terminal includes a first network and a second network, where the communication system of the first network is higher than that of the second network. Then, the terminal may determine the search priority corresponding to the first network as a first priority and determine the search priority corresponding to the second network as a second priority, wherein the first priority is higher than the second priority. As an example, the search priority for performing the high-system network search may be, for example, from high to low: 5G, 4G, 3G and 2G.
It should be understood that the search priority may be configured in the terminal in advance, for example, the terminal may also receive the search priority from other devices, and then configure the network searching order according to the received search priority, which is not limited in this application.
According to the method of the embodiment, the terminal can search the network with a higher communication system preferentially, so that higher-speed internet access service is provided for the user.
A method for network recovery provided by the embodiment of the present application is described above with reference to fig. 1. For the convenience of understanding the embodiment of the present application, a possible implementation flow of the network recovery method provided by the embodiment of the present application is described below with reference to fig. 2. As shown in fig. 2, the implementation process may include:
s201, start.
S202, whether the high-system network is switched to the low-system network is judged.
In this step, the terminal may determine whether the network to which the terminal accesses is switched from the high-standard network to the low-standard network. For example, a terminal drops from a 4G/5G network to a 2G/3G network. If the determination result in this step is yes, then S203 is executed; if the determination result is "no", S209 is executed to end the process.
S203, judging whether the duration of accessing the low-standard network exceeds a first duration.
The first duration may also be understood as a duration that the terminal lasts after being switched from the high-standard network to the low-standard network, or may also be understood as a duration that the terminal resides in the low-standard network after being switched from the high-standard network to the low-standard network. In this embodiment, the first duration may be a timing duration of a timer T, and a timing starting point of the timer may be a time when the terminal switches from the high-system network to the low-system network. As a possible implementation, the first duration may default to 60 seconds. If the determination result in this step is yes, then S204 is executed; if the determination result is "no", S209 is executed to end the process.
And S204, judging whether the screen is switched from the screen-off state to the screen-on state.
The terminal drops from a high-standard network (such as a 4G/5G network) to a low-standard network (such as a 2G/3G network), and under the condition that the residence time of the low-standard network exceeds the first time, the terminal can further judge whether the current screen state is changed from a screen-off state to a screen-on state. If the determination result is yes, executing S205; if the determination result is "no", S209 is executed to end the process.
And S205, judging whether the network is still in a low-standard network.
If the terminal detects that the screen state is switched from the screen-off state to the screen-on state, whether the current low-standard network (such as a 2G/3G network) is still in the low-standard network can be continuously judged. If the determination result is yes, executing S206; if the determination result is "no", S209 is executed to end the process.
And S206, searching the network in a high-standard mode.
When the terminal detects that the screen state is switched from the screen-off state to the screen-on state, optimization can be triggered, namely, high-system network searching is triggered to actively recover to a high-system network (such as a 5G/4G network).
S207, judging whether at least one of the following conditions occurs: switching on/off flight mode, talking, plugging/unplugging SIM card, searching network (such as high-standard network searching), and recovering to high-standard network.
If the determination result is yes, executing S208; if the determination result is "no", S209 is executed to end the process.
And S208, resetting the state.
If any at least one of the conditions in S207 occurs, the resettable state continues to monitor. The reset state may also be understood as a state of returning to the initial state of the terminal, that is, returning to a state in which the terminal starts monitoring whether the accessed network is switched from the high-standard network to the low-standard network.
And S209, ending.
According to the method of the embodiment, the network active recovery is carried out from the dimension of the screen-on of the terminal, so that the problem of power consumption caused by additional network searching when the terminal is in a low-standard network (such as 2G/3G) for a long time under the condition of screen-off is solved.
It should be understood that the method provided by the embodiment of the present application may be applicable to network recovery in a case of dropping a system (e.g., dropping from a high-system network to a low-system network), and may also be applicable to recovery of other abnormalities, for example, when a terminal is out of service, an attempt to actively recover from a dimension of a bright screen may also be performed.
Based on the foregoing embodiments, an apparatus for network recovery is provided in the embodiments of the present application, where the apparatus includes modules that can be implemented by a processor in a terminal; of course, the implementation can also be realized through a specific logic circuit; in the implementation process, the Processor may be a Central Processing Unit (CPU), a Microprocessor Unit (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
