First embodiment
In order to solve the problem in the related art that when a terminal performs data service transmission, a network is abnormal due to the problem that a signal is electromagnetically shielded or the network covers the terminal, and the network cannot be quickly recovered even in a switching scenario, in this embodiment, a network switching method is provided for solving the technical problem, please refer to fig. 3, where fig. 3 is a basic flowchart of the network switching method provided in this embodiment, and the network switching method includes:
s301, when a terminal transmits data service through a low-standard network, determining a current scene of the terminal according to data collected by a preset sensor combination;
s302, after the current scene is determined to be the target scene, when it is monitored that the terminal leaves the target scene currently, executing a preset operation to recover the network state of the terminal.
The method of the invention determines the current scene of the terminal according to the data collected by the preset sensor combination when the terminal transmits the data service through the low-standard network. After the current scene is confirmed to be the target scene, when the terminal leaves the target scene currently, preset operation is executed to recover the network state of the terminal, purposeful recovery of a terminal network can be achieved in some implementation processes, a user is helped to recover the network quickly, and the problems that when the terminal is switched to a low-standard network for data service transmission, even if the terminal leaves the application scene which is influenced by the influence and causes the terminal network to be abnormal, the network cannot be recovered quickly, and user experience is influenced are solved.
In some examples of this embodiment, the performing, by the terminal, data service transmission in the data service transmission through the low-standard network includes: data service transmission initiated before switching to the low-standard network and data service transmission initiated after switching to the low-standard network; for example, the application on the terminal performs data service transmission in the high-standard network, receives the application environment influence, and switches to the low-standard network to perform unfinished data service transmission in the high-standard network; or the application on the terminal initiates data service transmission after the terminal is switched to the low-standard network; at the moment, the terminal performs data service transmission through a low-standard network, and at the moment, the current scene of the terminal is determined according to data collected by a preset sensor combination.
In some examples of this embodiment, when the terminal performs data service transmission through the low-standard network, determining that the current scene of the terminal is ahead of the data collected by the preset sensor combination includes: and determining the standard networks which can be registered by the terminal, and dividing the standard networks which can be registered by the terminal into a high-standard network and a low-standard network. It should be understood that a terminal can generally register to a plurality of standard networks, and at this time, the standard networks to which the terminal can register are divided into a high-standard network and a low-standard network; for example, when the terminal can register to a 2G, 3G, 4G, 5G network, the 4G, 5G network is used as a high-standard network, and the 2G, 3G network is used as a low-standard network; when the terminal can register to the 2G and 3G networks, the 3G network is used as a high-standard network, and the 2G network is used as a low-standard network.
In some examples of this embodiment, determining the current scene of the terminal according to the data collected by the preset sensor combination includes: if the acceleration detected by the acceleration sensor continuously falls into a preset overweight or weightlessness threshold value and the air pressure value of the barometer has a preset air pressure change rule, determining that the current scene of the terminal is an elevator scene; if step counting data appear after the navigation information is collected, determining that the current scene of the terminal is a warehousing scene; if step counting data appears after the barometric pressure value collected by the barometer is continuously increased and navigation information is collected after the step counting data appears, determining that the current scene of the terminal is a warehouse-out scene; the target scenarios include, but are not limited to: the elevator scene, the warehousing scene and the ex-warehouse scene.
Specifically, multiple current scenes can be preset in this embodiment, each scene corresponds to different sensor combinations and different change rules of sensor combination data, and the current scenes at least include an elevator scene and a garage scene. In the elevator scenario, the example of the sensor combination including the pedometer, the barometer, and the acceleration sensor is exemplified in the present embodiment. After a user carrying a terminal enters an elevator, different data changes occur in a pedometer, a barometer and an acceleration sensor in the running process of the elevator, in an optional implementation mode, before the acceleration value is detected through the acceleration sensor, the current acceleration state can be sampled and subjected to average calibration, an abnormal value is calibrated for avoiding artificial actions during calibration, the abnormal average value can be directly taken as a fixed value, for example, 9.8, then the acceleration value is subjected to sampling detection, an optional mode is that if the current acceleration state falls within a preset overweight/weightlessness threshold for N times, an effective overweight/weightlessness event is considered, and the current scene of the terminal is determined to be an elevator scene in combination with regular changes of air pressure tested by the barometer. The value of the barometer can be continuously reduced under the condition that the elevator goes upstairs, the value of the barometer can be continuously increased under the condition that the elevator goes downstairs, the values detected in continuous preset time can be taken as a judgment basis when the values fall within a preset overweight/weightlessness threshold, and meanwhile, the step counting data of the pedometer can be combined to be taken as a judgment basis of an elevator scene without obvious change.
