Description

Scene-based terminal network searching strategy selection method and device, storage medium and terminal
Technical Field
The invention relates to the technical field of communication, in particular to a scene-based terminal network searching strategy selection method and device, a storage medium and a terminal.
Background
When a terminal (e.g., a Mobile phone, a Mobile computer, a smart watch, etc.) moves from an environment with poor network signals (e.g., an elevator with poor wireless signal coverage) to an environment with good network signals, the terminal may lose signal coverage or fall back to a Global System for Mobile Communication (GSM). According to business experience, a mobile phone text-only web page is generally opened, the network speed is required to be not lower than 10 kilobits per second (KB/s), music is required to be not lower than 20KB/s, and even a video format with 360 pixels (Pixel, or P or Px) with the lowest resolution requires a network speed of at least 100KB/s for a smooth video application.
Based on the above minimum Service requirements, Enhanced Data Rate for GSM Evolution (EDGE) or even General Packet Radio Service (GPRS) technology, which covers a poor elevator environment and has a weak signal, obviously cannot provide good user experience, and more examples are shielding of links in an elevator, maintaining of many links, failure to flush connected pages, and even complete network loss.
According to the protocol of the third Generation Partnership Project (3 GPP), after a terminal loses signal coverage, it first tries to camp on a Public Land Mobile Network (RPLMN) Registered in a card (such as a Subscriber Identity Module (SIM) card or a Universal Subscriber Identity Module (USIM) card, unless otherwise specified below, and immediately initiates a camping on a cell after the camping fails in the cell by using cell information previously camped on a Mobile phone, and after a long time of scanning, finds a currently existing Network, and then sequentially initiates a camping request according to priorities of the existing networks.
For a terminal residing in a GSM system, the terminal periodically detects different-frequency signals and different-system signals according to a received measurement instruction, and completes different-system reselection according to a reselection strategy configured by a network side according to the measurement signal or triggers the network side to be dispatched and switched to a cell of other systems through a measurement report.
According to the 3GPP TS 24.008 protocol and various terminal manufacturers, the terminal has no means for sensing the elevator environment, and if the terminal falls into a GSM cell or under a no-signal scene in the elevator environment, the terminal still periodically searches other standard cells or executes different-frequency adjacent cell measurement according to the protocol specification. This increases the handset power consumption.
Under this premise, the moment when the elevator door is opened is not matched with the network searching period and the measurement period, for example, if the terminal happens to perform full-band network searching and is searching for a Universal Mobile Telecommunications System (UMTS) network after Long Term Evolution (LTE) network searching is finished, even if the terminal leaves the elevator and arrives at an open area with good coverage, the terminal may not be able to return to the 4G network for the first time.
That is, the network of the existing under-network operator usually releases the radio resource when the 2G/3G network has no data service, so that the terminal returns to idle from the connected state and then reselects to 4G. And the problem of long time for returning to 4G and poor user experience can be caused by frequent and unproductive webpage refreshing of a mobile phone user.
In summary, the network searching strategy in the prior art cannot be accurately matched with the scene switching situation of the terminal, which may cause that the terminal cannot access a better network at the first time to affect user experience, or network searching continues in a scene without network signals to increase the power consumption of the terminal.

Detailed Description
As is known in the background art, a network searching policy in the prior art cannot be accurately matched with a scene switching situation where a terminal is located, which may cause that the terminal cannot access a better network at the first time to affect user experience, or that continuous network searching in a scene without network signals increases power consumption of the terminal.
In order to solve the above problem, an embodiment of the present invention provides a method and an apparatus for selecting a network searching policy of a terminal based on a scene, a storage medium, and a terminal, where the terminal includes a scene recognition sensor, and the method includes: monitoring the scene switching condition of the terminal through the scene recognition sensor; and when the scene where the terminal is located meets a preset condition, acquiring a network searching strategy corresponding to the preset condition, and executing network searching operation according to the acquired network searching strategy.
Therefore, the terminal can change the network searching strategy according to the scene where the terminal is located, and the problem that the network searching strategy cannot be accurately matched with the scene switching condition where the terminal is located in the prior art is solved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for selecting a network searching policy of a terminal based on a scene according to an embodiment of the present invention, where the method may be executed by a terminal side, the terminal side may refer to a computer, a mobile phone, a smart watch, and other terminal devices, and the terminal includes a scene recognition sensor.
The terminal network searching strategy selection method based on the scene comprises the following steps:
step S101, monitoring the scene switching situation of the terminal through the scene recognition sensor;
the scene recognition sensor is one or more sensors arranged on the terminal, and the sensor is used for detecting the scene where the terminal is located.
Optionally, the scene recognition sensor includes an acceleration sensor (G-sensor) and/or an air pressure sensor, and the preset condition is set according to a detection result of the acceleration sensor and/or the air pressure sensor.
Among them, the acceleration sensor is used to detect the motion condition of the terminal, such as horizontal motion, vertical motion, motion speed and acceleration of the terminal, etc. The air pressure sensor can be used for detecting the air pressure of the environment where the terminal is located. For a terminal, which is a mobile phone, a general smart phone is provided with an acceleration sensor, some high-end mobile phones are also provided with an air pressure sensor, and the environment (also called a scene) where the mobile phone is located can be determined through the acceleration sensor or the air pressure sensor or the combination of the acceleration sensor and the air pressure sensor.
Besides the acceleration sensor and the air pressure sensor, other sensors of the terminal may be used as the scene recognition sensor, for example, a Positioning sensor (such as a Global Positioning System (GPS) module), a magnetic sensor (M-sensor), an orientation sensor (O-sensor), a gyroscope, a gravity sensor, and the like. Therefore, the terminal can judge the scene according to the position, the magnetic field, the altitude and other factors of the terminal.
And step S102, when the scene where the terminal is located meets a preset condition, acquiring a network searching strategy corresponding to the preset condition, and executing network searching operation according to the acquired network searching strategy.
Wherein, the scene meeting the preset condition is called as the preset scene. When the terminal is in a preset scene, the network signal of the terminal may be poor or a network drop phenomenon may occur, for example, the preset scene may be an elevator, an underground parking lot, or in a high-speed rail/motor car, etc.
The network searching strategy corresponding to the preset condition is different from the existing network searching strategy and is a preset network searching strategy specially used for a preset scene.
For example, in a scenario (such as an elevator) where a terminal enters a signal with a poor quality, an existing network searching strategy is to periodically search for cells of other standards or perform inter-frequency neighbor cell measurement according to a protocol specification if the terminal drops into a GSM cell or a no-signal scenario. If the terminal is connected to the 2G/3G network with poor signals in the elevator, when the terminal leaves a scene with poor signals, such as when an elevator door is opened or when the terminal leaves the elevator, the terminal needs to wait for the 2G/3G network without data service to release wireless resources, so that the terminal returns to an idle state from a connection state and performs reselection to return to the 4G and 5G networks with good signals, and the terminal may not be accessed to the network with better signals at the first time, thereby affecting the user experience.
Alternatively, the unique movement pattern of the elevator can be detected by an acceleration sensor or an air pressure sensor, and the pressurization mode of the elevator car can be sensed to determine that the terminal is in the elevator.
In this embodiment, a scene where the terminal is located is monitored according to one or more sensors of the terminal, and when it is detected that the scene where the terminal is located is a preset scene, network searching is performed according to a network searching policy corresponding to a preset condition instead of performing network searching according to an existing network searching policy. Therefore, the terminal can change the network searching strategy according to the scene where the terminal is located.
In one embodiment, the situation in which the terminal is located meets a preset condition includes that the terminal is switched from a communication limiting situation to a normal communication situation, and the network searching strategy corresponding to the preset condition includes that network searching operation is executed according to a network system resident before the terminal enters the communication limiting situation.
When the terminal is in an environment where the communication restriction scene is that the terminal enters a poor signal, a network system used by the terminal is passively reduced (for example, the terminal falls from a 4G network to a 2G/3G network), or a no-network signal is sent.
The terminal is switched from the communication limiting scene to the normal communication scene, namely, the network leaves the environment with poor signals, and the terminal can recover to the network system that the terminal is switched from the communication limiting scene to the normal communication scene, or the network signal of the terminal is retrieved.
Optionally, the switching of the terminal from the restricted communication scenario to the normal communication scenario includes leaving the restricted communication scenario such as an elevator or an underground parking garage by the terminal. At this time, the terminal does not periodically search for cells of other systems or perform inter-frequency neighbor cell measurement according to the protocol specification, but searches for a network by adopting a network searching strategy corresponding to a preset condition. The terminal can execute network searching operation according to the network system resident before the terminal enters the restricted communication scene, and if the terminal resides in the 4G network before entering the elevator or the underground parking lot, the network searching operation is started from the 4G network system after the terminal leaves the elevator or the underground parking lot.
Optionally, referring to fig. 1 and fig. 2, the executing, according to the obtained network searching policy, a network searching operation in step S102 in fig. 1 may include:
step S201, obtaining connection information of a highest network type network residing in a preset time period before the terminal enters a communication limiting scene from a preset storage position;
the preset storage position is used for storing the connection information of the terminal residing in the network. Alternatively, the preset storage location may store connection information of one or more networks in which the terminal resides. Further, the terminal may store connection information of a network of the highest network type in which the terminal resides. The "highest network system network" refers to a network of the network system with the highest data transmission rate or the best communication quality.
Optionally, the connection information includes types of network types (e.g., 2G, 3G, 4G, 5G, etc.), registration information of the terminal accessing the network, and the like.
The duration of the preset time can be set as required, such as half an hour, one hour and the like. Due to factors such as a building structure of a place, a network system used by the terminal may have been passively reduced before the terminal enters a limited communication scene such as an elevator/underground parking lot, and the highest network system network where the terminal resides in a preset time can reflect the communication capacity of the terminal in a normal communication scene.
The terminal stores the connection information of one or more networks where the terminal resides in a preset storage position, and when the terminal is identified to enter a communication limiting scene according to the scene identification sensor, if the network system used by the terminal is passively lowered or no signal occurs, the connection information of the network with the highest network system where the terminal resides in the preset time before the terminal is lowered or no signal can be obtained from the preset storage position. And when the terminal is switched from the limited communication scene to the normal communication scene, acquiring the connection information from a preset storage position, and judging whether to search for the network again according to the connection information.
Optionally, a Camp information Database (Camp Operator Database) may be maintained at a preset storage location on the terminal side to store the connection information. Further, the preset storage position is located in the SIM/USIM card.
Step S202, judging whether the network type corresponding to the connection information is higher than the network type when the terminal enters a communication limiting scene;
if the determination result in step S202 is yes, step S203 is executed to start the network searching operation.
If the network type used when the terminal enters the restricted communication scene is passively reduced, when the terminal enters the normal communication scene again, the network type corresponding to the connection information acquired by the terminal is higher than the network type when the terminal enters the restricted communication scene, at the moment, the network searching operation is immediately executed, and the terminal is directly triggered to access the network with the higher network type.
At this time, the difference between the network searching strategy corresponding to the preset condition and the existing network searching strategy is that if the terminal is switched from the restricted communication scene to the normal communication scene and the network type corresponding to the acquired connection information is higher than the network type when the terminal enters the restricted communication scene, the network searching operation is immediately started. The network searching is executed without waiting for the period of the next network searching or waiting for no data service of the currently connected network.
Optionally, before starting to perform the network searching operation in step S203, the method may further include: detecting whether the terminal is carrying out a preset service or not; and if the detection result is yes, after the preset service is ended, executing the network searching operation.
When the terminal is carrying out the preset service, in order to avoid the interruption of the preset service, after the service is finished, the network searching operation is executed. The preset services are services such as telephone, video telephone and the like which need to be supported by a continuous network.
Optionally, after the network searching operation is started in step S203, the method may further include: and preferably starting network searching from the network system corresponding to the connection information.
For restricted communication scenes such as elevators and underground parking lots, the network system of the cell to which the terminal belongs is basically unchanged, and network searching can be started from the network system corresponding to the acquired connection information preferentially so as to improve network searching efficiency.
Optionally, if the determination result in the step S202 is negative, the step S204 is executed, and the network searching operation is not executed. At the moment, the network system of the terminal entering the communication limiting scene is not passively reduced, and the network searching is not needed again.
In this embodiment, if the network type used when the terminal enters the restricted communication scenario is passively decreased, after the terminal is switched from the restricted communication scenario to the normal communication scenario, except for the situation that the terminal is performing the preset service, the terminal can immediately perform a network searching operation, trigger the terminal to access the network with the higher network type, ensure the communication requirement of the user, and improve the user experience.
In a specific embodiment, the network standard of the resident network before the terminal enters the elevator is 4G, and the terminal passively falls to 2G/3G after entering the elevator. When the elevator door is detected to be opened, the network parking information before the elevator is detected, and the network capability information of the operator to which the SIM card/USIM card used by the terminal belongs are comprehensively judged, if the operator supports the 4G network and recently resides in the 4G network, a 4G cell search process is triggered, a historical 4G cell is preferentially tried, and the terminal can return to the 4G mode as soon as possible to improve user experience.
In one embodiment, the condition that the terminal is located meets the preset condition comprises that the terminal is switched from a normal communication scene to a limited communication scene; the network searching policy corresponding to the preset condition may include: and if the terminal fails to search the network in the communication limiting scene, the time interval between two times of initiating network searching operations is increased or the network searching operations are not initiated any more.
If the terminal is in the limited communication scene and network drop occurs and the first round of network searching fails, network searching actions are not initiated or the time interval between network searching operations is increased when the terminal is in the limited communication scene, so that the power consumption of the terminal is saved.
Optionally, the motion of the elevator is sensed through the acceleration sensor and/or the pressure sensor, the network searching action is not initiated any more during the running of the elevator, and the network searching action is initiated immediately after the motion of the elevator stops.
In an embodiment, the preset condition includes a preset model, the method further includes a generation manner of the preset model, please refer to fig. 3, and fig. 3 is a schematic flow chart of the generation manner of the preset model, including:
step S301, when the scene where the terminal is located is switched, the change condition detected by the scene recognition sensor is obtained;
and step S302, generating a preset model according to the change condition.
The preset model is generated according to the detection result of the recognition sensor corresponding to the preset scene and used for detecting whether the scene where the terminal is located meets the preset condition or not. The method can be used for establishing a preset model corresponding to a preset scene in advance and storing the preset model in the terminal side so that the terminal can detect whether the scene where the terminal is located is the preset scene according to the preset model.
Optionally, the preset model may be a big data model to accurately determine whether the terminal is in the preset scene.
Optionally, when the scene recognition sensor includes an acceleration sensor and/or an air pressure sensor, the change condition detected by the scene recognition sensor includes an acceleration change waveform detected by the acceleration sensor and/or a pressure change waveform detected by the air pressure sensor.
Correspondingly, please continue to refer to fig. 1, in step S101, the monitoring of the scene switching situation of the terminal by the scene recognition sensor may include: acquiring a detection result of the scene recognition sensor in real time; and when the detection result is matched with the preset model, the scene where the terminal is located meets the preset condition.
When a detection result obtained by monitoring of the scene recognition sensor is matched with a pre-stored preset model, the scene where the terminal is located can be determined to meet the preset condition, and network searching strategy selection of the terminal is triggered.
