Description

Terminal and cell reselection method

Technical Field

Background

With the intellectualization of terminals (such as mobile phones) and the continuous development of network technologies, various network forms including a 4G network and an 2/3G network have been commonly applied to the current terminals, but for the terminals themselves, the battery power limits the use and the endurance time of the terminals. Under the conditions of the prior art and network coverage, the terminal is likely to be in a weak signal environment of a certain network, for example, in an environment where the 4G signal is weak and the 2/3G signal is wide in coverage, frequent different network handovers may occur to the terminal, for example, handovers from 4G to 2/3G, because many users may set up to preferentially connect to the 4G network due to the advantage that the 4G signal is fast, and when the 4G signal is unstable, the terminal will tend to frequently handover between 4G and 2/3G, which necessarily results in increased power consumption of the terminal and accelerates the consumption of battery power. On the other hand, in the information of the interaction between the modem and the base station, the modem is generally reported to the AP of the client, the modem interacts with the AP, and the power consumption is increased when the AP is awakened each time. When the terminal operates in a weak signal environment, the power consumption of the terminal is multiplied every time the terminal is awakened, so that the consumption speed of the battery is multiplied.

More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may beA server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive a broadcast signal by using a signal such as multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO)^@) A digital broadcasting system of a terrestrial digital broadcasting integrated service (ISDB-T), etc. receives digital broadcasting. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 1220, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the camera 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 1210 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 1410 as will be described below in connection with a touch screen.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, 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 showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 1810 for reproducing (or playing back) multimedia data, and the multimedia module 1810 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cell sites". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above optional mobile terminal hardware structure and communication system, various embodiments of the method of the present invention are proposed.

As shown in fig. 3, a first embodiment of the present invention proposes a terminal 1 including: a first detection module 11, a second detection module 12, a residence module 13 and a control module 14.

The first detecting module 11 is configured to detect whether a current environment is a preset environment when a signal of a first network cell of the terminal is less than or equal to a preset first intensity threshold.

The second detecting module 12 is configured to detect whether the signal strength of the wireless fidelity WIFI network in the preset environment is greater than or equal to a preset second strength threshold value when the current environment is the preset environment.

And a residence module 13, configured to, when the signal strength of the WIFI network is greater than or equal to the second strength threshold, reside in the second network cell after the control module 14 controls the terminal to switch from the first network cell to the second network cell.

Optionally, the detecting, by the first detecting module 11, whether the current environment is a preset environment includes:

positioning the current position through a Global Positioning System (GPS);

Optionally, the first network cell is a long term evolution, LTE, cell; the device also includes: a determination module 15.

A determining module 15, configured to determine that the preset environment is not registered to the voLTE network before the camping module controls the terminal to camp on the second network cell.

Optionally, the apparatus further comprises: a data traffic module 16.

And the data service module 16 is configured to perform a data service through the WIFI network after the residing module control terminal resides in the second network cell.

Optionally, the control module 14 is further configured to: controlling the terminal to switch from the second network cell to the first network cell when any one or more of the following conditions are met:

the WIFI network is closed;

the current environment is not the preset environment.

In addition, in order to achieve the above object, the present invention further provides a cell reselection method, as shown in fig. 4, it should be noted that any embodiment in the method embodiment is applicable to the above device embodiment, and details are not repeated herein. The method comprises S101-S103:

s101, when a signal of a first network cell of the terminal is smaller than or equal to a preset first intensity threshold value, detecting whether the current environment is a preset environment.

In the embodiment of the present invention, if the terminal is in a weak signal environment of a certain network, for example, in some current areas, the 4G signal may be weak due to network planning, and the 2/3G signal has a wider coverage. When the terminal is in such an environment for a long time, the terminal may register 2/3G network first, meanwhile, the terminal may initiate neighbor cell measurement to the serving cell, and when receiving a paging message of a 4G signal and satisfying a certain residence criterion, may initiate 4G registration. When the terminal moves within this weak signal area, or when the 4G signal becomes worse, the terminal failing to meet the 4G dwell criterion may revert to 2/3G mode dwell. In the network switching process, on one hand, a terminal needs to interact with a base station, and modules such as a radio frequency antenna and the like have larger power consumption, and on the other hand, under a weak signal, the power and the like which the terminal needs to send are also increased to ensure normal coding and decoding, so that the working current of the whole terminal is larger, and the power consumption is also increased. In order to solve the problem of excessive terminal power consumption caused by frequent switching among multiple networks, when the scheme of the embodiment of the invention determines that an LTE network (namely, a 4G network) is only used for data service, the WIFI network in a common environment can replace the 4G network to carry out the data service, so that the current terminal only resides on an 2/3G network, and the problem of excessive terminal power consumption caused by back-and-forth registration of the terminal between the 4G network and a 2/3G network is avoided.

In the embodiment of the present invention, first, the signal strength of the first network cell, for example, the 4G cell, needs to be detected to determine whether the first network cell is in a weak signal state.

Optionally, detecting the signal strength of the first network cell, such as the 4G cell, may include: the signal strength of the first network cell is detected periodically or in a message manner.

In the embodiment of the present invention, the signal strength of the first network cell is detected by using a periodic detection method, that is, the signal strength of the first network cell is detected once every time a preset period passes, and the preset period may be defined by itself according to different application scenarios without specific limitations. The signal strength of the first network cell is detected in a message notification manner, that is, when the signal strength of the first network cell is less than or equal to a certain preset threshold, a message notification is sent to a related module or a control unit of the terminal, where the message notification includes information that the signal strength of the first network cell is less than or equal to the preset threshold. Similarly, the preset threshold may also be defined by itself according to different application scenarios, without specific limitations.

It should be noted that, the detection method or algorithm used in each detection is not specifically limited, and any method or algorithm capable of detecting the signal strength of the first network cell is within the protection scope of the embodiment of the present invention.

In the embodiment of the present invention, after the signal strength of the first network cell is detected by the above-mentioned scheme, it is required to compare the detected signal strength with a preset signal threshold, that is, the above-mentioned first strength threshold, to further determine whether the signal strength is in the weak signal state, where the first strength threshold is a lower limit value of a network signal strength range, and when the detected signal strength is lower than the lower limit value, it is determined that the signal strength is in the weak signal state, that is, when the signal strength of the first network cell is smaller than or equal to the preset first strength threshold, it is determined that the first network is in the weak signal state, and otherwise, when the detected signal strength is higher than the lower limit value, it is determined that the signal strength is not in the weak signal state. The preset first intensity threshold may be defined by itself according to different application scenarios, and is not particularly limited.

Optionally, in order to further determine that the network strength of the first network cell is maintained in a weak signal state, and is not an accidental phenomenon, when the detection results of n consecutive detections are all that the signal strength of the first network cell is less than or equal to a preset first strength threshold, it may be determined that the first network cell is in the weak signal state, where n is a positive integer, n ≧ 2, and the magnitude of n may be defined according to a specific application scenario. In addition, in order to consider the fluctuation situation of the network, the value of n cannot be set too large, so as not to lose the meaning of the scheme of the embodiment of the invention.

In the embodiment of the present invention, after determining that the signal strength of the current first network cell is really less than or equal to the preset first strength threshold through the above scheme, it may be further determined whether the current environment is a preset environment, for example, a common environment, so that internet access may be performed through a WIFI network in the preset environment, and the first network cell, for example, an LTE cell, is no longer connected, so as to avoid an increase in internal consumption of the terminal due to repeated registration of the first network cell caused by instability of the first network cell. Specifically, whether the current environment is the preset environment can be determined through the following scheme.

Optionally, as shown in fig. 5, the detecting whether the current environment is the preset environment includes S201 to S203:

s201, positioning the current position through a Global Positioning System (GPS).

In the embodiment of the present invention, since the positioning function is basically realized by various current intelligent terminals, when it is detected that the signal of the first network cell is less than or equal to the preset first intensity threshold, that is, the first network cell is in a weak signal state, the GPS function can be automatically started to position the current location. Here, what kind of GPS positioning function is specifically adopted is not limited, and may be defined by itself according to different application scenarios. For example, the positioning function may be built in the terminal, or the third-party GPS software may be used.

In the embodiment of the present invention, in addition to the positioning by the GPS positioning scheme, the positioning may be performed by an SSID (Service set identifier) of a wireless local area network and a serving cell id (serving cell network cell id) without a GPS or in combination with the GPS positioning scheme. The specific positioning method is not limited herein, and any one or more of the above manners may be adopted to perform the current position positioning, and other suitable positioning methods may also be adopted, and any solution that can achieve the current position positioning is within the protection scope of the embodiment of the present invention.

S202, comparing the position determined by positioning with a pre-stored common position.

In the embodiment of the invention, one or more common positions can be stored or set in advance, and the common positions need to be pre-installed with the WIFI network, so that the data service of the first network cell can be converted into the data service realized through the WIFI network after the current position is determined, and the increase of the internal consumption of the terminal caused by repeatedly registering the first signal cell under the condition that the signal of the first network cell is weaker is avoided. It should be noted that the common location may be a location where a user confirms safety, such as a home location and an office location, and public locations, such as mcdonald, starbucks, and shopping malls, are avoided as much as possible, so as to prevent the personal privacy of the user from being stolen through public WIFI.

In the embodiment of the present invention, after the current position is located in step S201, the position determined by the location determination may be compared with the above-mentioned pre-stored common position, so as to determine whether the position determined by the current location is a common position.

And S203, when the position determined by positioning is the same as any one of the pre-stored common positions, determining the environment where the current position is located as a preset environment.

In the embodiment of the present invention, after the position determined by the positioning is compared with the pre-stored common positions in step S202, it can be determined whether the current environment is the preset environment according to the comparison result, and here, as long as the position determined by the positioning is the same as any one of the pre-stored common positions, the environment where the current position is located can be determined as the preset environment.

It should be noted that, in order to accurately locate the current position of the user, the positioning software or the positioning function adopted by the terminal needs to reach a certain accuracy, for example, within three meters.

S102, when the current environment is a preset environment, detecting whether the signal intensity of the wireless fidelity WIFI network in the preset environment is larger than or equal to a preset second intensity threshold value.

In the embodiment of the present invention, when it is determined that the current location is the location of the preset environment, it may be further detected whether the signal strength of the WIFI network in the current environment is greater than or equal to a preset second strength threshold, or whether a WIFI signal exists in the current environment is detected first. Therefore, the WIFI network in the current environment is determined, the current WIFI network can meet normal data services, the phenomenon that the terminal repeatedly requests to connect the WIFI network when the current WIFI signal is poor can be avoided, and the internal consumption of the terminal is increased.

And S103, when the signal intensity of the WIFI network is greater than or equal to a second intensity threshold value, after the control terminal is switched from the first network cell to the second network cell, the control terminal resides in the second network cell.

In the embodiment of the invention, if the signal intensity of the current WIFI network is detected to be greater than or equal to the second intensity threshold value, the current WIFI network signal can be determined to be good enough to meet the normal data service, so that the data service of the terminal can be transferred to the WIFI network from the second network cell. And if it is detected at this time that the terminal has automatically fallen back to the second network cell because the signal of the first network cell is too weak, the current terminal can be kept residing in the second network cell. It should be noted that the network of the second network cell is smaller than the network speed of the first network cell, for example, the second network cell may be a 4G cell (or an LTE cell), the second network cell may be an 2/3G cell, when the 4G cell does not satisfy the residence criterion, the terminal may automatically return to the 2/3G cell mode, and at this time, the terminal may always reside in the 2/3G cell to satisfy the basic voice service, and implement data service communication through the WIFI network.

Optionally, the first network cell is a long term evolution, LTE, cell; the method further comprises the following steps: determining that the preset environment is not registered to the voLTE network before the control terminal resides in the second network cell.

In the embodiment of the present invention, if the first network cell is a long term evolution LTE cell, before the control terminal resides in the second network cell, the preset environment needs to be further determined, where the common environment is not registered in the voice long term evolution voLTE network, that is, the voice service cannot be performed through LTE in the preset environment. If it is detected that the preset environment has registered the voLTE network, the current terminal may perform the voLTE service through the first network cell, and the first network cell cannot be directly cut off, and further attempt to connect the first network cell is required to avoid affecting the voLTE service. It should be noted that, whether to keep reconnecting to the first network cell may be determined according to the actual needs of the user, and is not limited in this respect, or a confirmation window indicating whether to camp on the second network cell is displayed before camping on the second network cell for the user to select. If the current user considers that the voLTE service is not used recently, the user can directly reside in a second network cell; on the contrary, if the current user considers that the voLTE service is used recently, the scheme of the embodiment of the present invention may be abandoned, and the user does not always stay in the second network cell and tries to connect to the first network cell.

In the embodiment of the present invention, it can be known from the above contents that if the scheme of the embodiment of the present invention is adopted, the connection with the first network cell can be temporarily disconnected, and a data service is implemented through the WIFI network, because the WIFI network also has a faster network speed, the network requirements of the user can be met, so that the user can meet a normal voice service through the second network cell having a slower network speed without affecting the normal internet access service, and at the same time, the internal consumption can be reduced, the electric quantity of the terminal can be maintained, and the user experience is greatly improved.

the WIFI network is closed;

the current environment is not the preset environment.

In the embodiment of the present invention, after the control terminal resides in the second network cell, if a situation occurs, such as the WIFI network is turned off or the signal strength of the WIFI network is smaller than the second strength threshold, in order to enable the current user to implement a normal data service (i.e., an internet access service) and ensure the network speed requirement of the user, the control terminal needs to be further switched from the second network cell to the first network cell. Or if the current environment is detected not to be the preset environment, the terminal cannot be connected to the WIFI network containing unsafe factors such as public WIFI because whether the current WIFI is safe or not cannot be determined, so that personal information, confidentiality or privacy of the user can be prevented from being stolen through the public WIFI. Or, if it is detected that the signal of the current first network cell is greater than the preset first intensity threshold, it indicates that the current first network cell has maintained the normal signal intensity, and the network requirement of the user can be met, so that the terminal may automatically switch from the second network cell back to the first network cell, or jump out of a preset selection window, and the user determines whether to switch from the second network cell back to the first network cell.
