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 be a 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 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 122, 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 module 151. The image frames processed by the cameras 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 121 may be provided according to the configuration of the mobile terminal, in this scheme, more cameras are required to implement image acquisition and related data processing for the control body. 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 module 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. Generally, the sensing unit 140 includes a distance sensor 141, and the distance sensor 141 in the sensing unit 140 processes distance detection in a phone answering process implemented near the audio output module 152.
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 an "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 module 151, an audio output module 152, an alarm module 153, and the like.
The display module 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 module 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 module 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 module 151 and the touch pad are stacked on each other in the form of layers to form a touch screen, the display module 151 may serve as an input device and an output device. The display module 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. The mobile terminal 100 may include two or more display modules (or other display devices) according to a particular desired implementation, for example, the mobile terminal may include an external display module (not shown) and an internal display module (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 module 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 module 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm module 153 may provide an output in the form of a vibration, and when a call, a message, or some other incoming communication (incomingmunication) is received, the alarm module 153 may provide a tactile output (i.e., a 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 module 153 may also provide an output notifying the occurrence of an event via the display module 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 181 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.

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 "cells". 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 mobile terminal hardware structure and communication system, various embodiments of the network switching method of the mobile terminal of the present invention are proposed.
Please refer to fig. 3A, which is a flowchart illustrating a method for network handover of a mobile terminal according to a first embodiment of the present invention, wherein the method includes the following steps:
s11: and confirming that the current network is the first connection mode of preferential connection, and acquiring the actual transmission parameters of the current network.
Generally, the network connection mode of the mobile terminal is mainly two from the transmission process. One is to directly access the network, for example, access the network in a mobile communication mode through a SIM card; the other is to access other network intermediary devices through various short-distance wireless communication modes to access the network, such as Wi-Fi network card access to Wi-Fi, or network bluetooth sharing through bluetooth chip access to other mobile terminals. And most of the cases are that the network connection of the mobile terminal is realized through the SIM card and the Wi-Fi network card.
As for the use habit of the user, which access network of the SIM card or the Wi-Fi network card is selected freely, and certainly, the default in the prior art is to access the wireless network through the Wi-Fi network card, specifically, as shown in fig. 3B, two network modes, the higher priority being the Wi-Fi network card mode. The user can select to access the network preferentially through the SIM card, at the moment, the first connection mode is SIM card access, and the second connection mode is Wi-Fi network card access; or selecting to access the network preferentially through the Wi-Fi network card, wherein the first connection mode is Wi-Fi network card access, and the second connection mode is SIM card access. Under the condition of one access, the other access is disconnected and forbidden, so that the problems of unsmooth data transmission and increased power consumption caused by network state change in the using process are avoided.
For network data transmission, the transmission actual parameters describing the actual state of the data transmission include the data sending rate, the data receiving rate and the strength indication of the current network signal.
The data transmission rate (tx) refers to a data transmission rate when the mobile terminal sends information to the outside, for example, a data transmission rate when the mobile terminal sends information to the network from a Wi-Fi hotspot through a Wi-Fi network card.
The data reception rate (rx) is a data transmission rate at which the mobile terminal receives information inputted from the outside, for example, a data transmission rate at the time of receiving information transmitted from the base station by the SIM card.
The Strength indication (rssi) of the current network Signal is used for describing the broadband receiving power, the Strength indication of the current network Signal is obtained by performing power integration in a digital domain and then performing back-stepping on an antenna port, and the parameter is used as a basis for judging system interference.
The transmission speed and the state stability of the current network are described through the parameters, and then the parameters are used as a judgment standard for judging whether the network connection is switched.
S12: and reading a preset transmission lower limit parameter of the first connection mode, and comparing the transmission actual parameter with the transmission lower limit parameter.
The transmission lower limit parameter is used for describing the lowest tolerance state in a connection mode and is a comparison standard for subsequent judgment, if the actual connection state is better than the lowest tolerance state, the current connection state is naturally maintained, and network connection and data transmission are continued; if the actual connection state is worse than the lowest tolerance state, the network connection is switched and the second connection mode is entered to obtain a better network connection state.
The transmission lower limit parameter may be the same or different for different connection modes. Generally speaking, the transmission speed of the Wi-Fi network is higher than that of the mobile communication network, and if the same transmission lower limit parameter is adopted, the Wi-Fi network card mode is switched to the SIM card mode only when one Wi-Fi hotspot accesses a large number of terminals or a certain terminal occupies a large number of transmission resources. Certainly, with the rapid development of mobile communication technology, the transmission speed of the SIM card mode has been greatly improved, and both have quite close transmission capabilities, and can set the same transmission lower limit parameter, and also ensure the accurate switching of network connection. For older mobile communication networks, it is preferable to set the SIM card mode and the Wi-Fi network card mode to different transmission lower limit parameters.
S13: and when the actual transmission parameters are all correspondingly lower than the lower transmission limit parameters, switching the current network into a standby second connection mode.
It should be noted that, in the present solution, the current network is switched only when all the actual transmission parameters are lower than the corresponding transmission lower limit parameters, and if one or two of the actual transmission parameters are slightly lower than the corresponding transmission lower limit parameters, the current network connection does not need to be switched, and the current status is maintained.
The network switching method of the mobile terminal of the embodiment judges the transmission actual parameter in the current network connection state by confirming the connection mode of the current network, and switches the network connection mode according to the comparison between the transmission actual parameter and the preset transmission lower limit parameter; the method and the device realize that the mobile terminal realizes the quick confirmation of the connection mode while ensuring the network speed in a multi-network connection mode, and maintain the stability of the data transmission of the mobile terminal.
Please refer to fig. 4A, which is a flowchart illustrating a method for network handover of a mobile terminal according to a second embodiment of the present invention, wherein the method includes the following steps:
s21: and confirming the first connection mode of the prior connection of the current network, and acquiring the transmission actual parameters of all connection options of the first connection mode.
For the mobile terminal with multiple SIM cards and multiple Wi-Fi network cards, a plurality of connection options are correspondingly arranged in one connection mode. As shown in fig. 4B and 4C, the connection options of the multiple SIM cards include SIM card 1 and SIM card 2, where the priority of SIM card 1 is higher than that of SIM card 2; the connection options of the plurality of Wi-Fi network cards at least comprise a Wi-Fi network card 1 and a Wi-Fi network card 2, wherein the priority of the Wi-Fi network card 1 is higher than that of the Wi-Fi network card 2. Before network switching, the transmission actual parameters of all connection options in one connection mode need to be judged.
S22: and reading a preset transmission lower limit parameter of the first connection mode, and comparing the transmission actual parameter with the transmission lower limit parameter.
And comparing the transmission actual parameters corresponding to all the connection options with the transmission lower limit parameter. For example, if the SIM card connection is in the first connection mode, the transmission actual parameter of the SIM card 1 in fig. 4B is correspondingly compared with the transmission lower limit parameter; the actual transmission parameters of the SIM card 2 are compared with the lower transmission limit parameters to determine whether the first connection mode is normal.
S23: and broadcasting a message for starting the second connection mode when the transmission actual parameters are all correspondingly lower than the transmission lower limit parameter.
And when the actual transmission parameters are all correspondingly lower than the lower transmission limit parameters, triggering broadcast, and sending a message for starting the second connection mode, namely the Wi-Fi chip connection mode, to a control device for controlling the second connection mode to work, such as a Wi-Fi chip.
Further, if the transmission actual parameters of one connection option in the first connection mode are all correspondingly lower than the transmission lower limit parameter, for example, the Wi-Fi network card 1; and the actual transmission parameters of the other connection option are all higher than the lower transmission limit parameters, such as the Wi-Fi network card 2, the network is preferentially switched from the Wi-Fi network card 1 connection mode to the Wi-Fi network card 2 connection mode, so that the connection type of the first connection mode is ensured not to be changed.
S24: and acquiring connection options of the second connection mode, and accessing the connection option with the highest priority or the strongest signal in the connection options.
For the connection option of the second connection mode, the priority of each connection option may be preset, and of course, the determination may also be performed according to the signal strength of the connection option.
S25: the first connection mode is disconnected.
When the network is connected, only one connection mode is reserved so as to reduce the fluctuation of the network connection state and avoid data transmission errors and the increase of the power consumption of the mobile terminal caused by the switching of the network connection state in the data transmission process.
S26: and if the second connection mode fails to be connected, switching the current network into the first connection mode.
If the second connection mode fails to connect, the mobile terminal cannot access the network after the network is switched to the second connection mode, and the normal use of the mobile terminal is affected. And switching the current network back to the first connection mode to ensure that the network connection of the mobile terminal is available.
S27: and outputting a network switching instruction receiving window when the transmission actual parameter part is correspondingly lower than the transmission lower limit parameter.
If the actual transmission parameter part is lower than the lower transmission limit parameter, the network connection may be switched or not, at this time, as shown in fig. 4D, a network switching instruction receiving window is output on the screen of the mobile terminal, and when an instruction is received, the network is switched to the connection mode to which the instruction points and the corresponding connection option in the mode.
