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 a mobile communication module 111.

The mobile communication module 111 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. For example, in the embodiment of the present invention, the number of the mobile communication modules 111 is preferably two, and the mobile communication modules 111 are used to respectively implement the first modem processing module and the first radio frequency module, and the second modem processing module and the second radio frequency module of the embodiment of the present invention.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a microphone 121, and the microphone 121 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and may be capable of processing 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 111 in case of a phone call mode. The microphone 121 may implement various types of noise canceling (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting an audio signal. In an embodiment of the present invention, the microphone 121 is used to implement a digital signal processing module and a voice input module of an embodiment of the present invention.

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 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 unit 151, an audio output module 152, 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. In an embodiment of the present invention, the audio output module 152 is used to implement a voice output module in an embodiment of the present invention.

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. 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. For example, in the present embodiment, two controllers 180 are preferred for implementing the first application processing module and the second application processing module of the embodiment of the present invention, respectively.

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 first application processing module 101 runs an operating system (e.g., android system) of the mobile terminal and various applications to provide an interactive interface for the user, which may be the controller 180 in fig. 1. The second application processing module 201 is a processor with a relatively weak processing capability compared to the first application processing module 101, and only plays a role of transparent transmission, that is, data, information, and the like are not processed, but are directly transmitted to the first application processing module 101 or the second modem processing module 202.

With reference to fig. 2 and 3 in combination, in a preferred embodiment of the mobile terminal 100 of the present invention, the mobile terminal 100 includes a first modem processing module 201, a second modem processing module 202, and a two-way Wi-Fi module, where the two-way Wi-Fi module includes a first application unit 01, a second application unit 02, a service unit 30, a first Wi-Fi unit 40, and a second Wi-Fi unit 50, the first modem processing module 201 is configured to extract and establish a connection with a corresponding first operator network based on first card information of a first subscriber identification card connected thereto, and extract and send second card information of a second subscriber identification card connected thereto to the second modem processing module 202, so that the second modem processing module 202 establishes a connection with a corresponding second operator network;

the service unit 30 is configured to, when receiving a connection instruction issued by the first application unit 01 or the second application unit 02 in response to a user operation, issue the received connection instruction to the first Wi-Fi unit 40 or the second Wi-Fi unit 50 correspondingly;

and when one of the first Wi-Fi unit 40 and the second Wi-Fi unit 50 establishes an air interface connection, loading a preset single data access route configuration.

In this embodiment, the first modem processing module 102 extracts card information of the first subscriber identity card, wherein the card information includes ICCID (integrated circuit card identification code), IMSI (International Mobile subscriber identity), and the like required for network search registration and authentication, after extracting the card information of the first subscriber identity card, the first modem processing module 102 determines an operator (such as Mobile, telecommunication, and telecommunications) to which the first subscriber identity card belongs according to the card information of the first subscriber identity card, and establishes a radio connection with a carrier base station corresponding to the first subscriber identity card through the first radio frequency module 103 based on the card information according to radio frequency signals (carrying identification information of the operator) received by the first radio frequency module 103 connected thereto from different carrier base stations, and after completing an authentication operation of the first subscriber identity card using the card information, and establishing connection with a first operator network corresponding to the first subscriber identity card.

When the first modem processing module 102 establishes a connection with a first operator network corresponding to a first subscriber identity card connected thereto and receives an access request of the second modem processing module 202 for a second subscriber identity card, it extracts card information of the second subscriber identity card and sends the card information to the second modem processing module 202, so that the second modem processing module 202 performs a network searching registration operation and an authentication operation.

After receiving the card information of the second subscriber identity card sent by the first modem processing module 102, the second modem processing module 202 performs a network searching registration operation and an authentication operation using the received card information to establish a connection with the second carrier network corresponding to the second subscriber identity card. Specifically, the second modem processing module 202 determines an operator (such as mobile, telecommunication, and internet operator) to which the second subscriber identity card belongs according to the received card information, and according to a radio frequency signal (carrying identification information of the operator) received by the second radio frequency module 203 connected thereto from a base station of a different operator, establishes a radio connection with the base station of the operator corresponding to the second subscriber identity card through the second radio frequency module 203 based on the card information, and establishes a connection with a network of the second operator corresponding to the second subscriber identity card after completing an authentication operation of the second subscriber identity card using the card information.

1. in the process of making the data service through the first subscriber identity card, the mobile terminal 100 may still make the data service through the second subscriber identity card, for example, when the user uses the mobile terminal 100 to download a movie through the first operator network corresponding to the first subscriber identity card in the background, the user may still browse a web page through the second operator network corresponding to the second subscriber identity card in the foreground, and the two are not mutually affected.

2. In the process of using the first subscriber identity card to perform the CS voice service, the mobile terminal 100 may still use the second subscriber identity card to perform the data service, for example, when the user uses the mobile terminal 100 to make a call through the CS voice service of the first operator network corresponding to the first subscriber identity card, the user may still download a movie in the background through the second operator network corresponding to the second subscriber identity card.

3. The mobile terminal may implement service acceleration through the dual 4G networks in the process of executing data services such as downloading or video browsing, for example, when a user uses the mobile terminal 100 to watch an online movie, the mobile terminal 100 may split corresponding streaming media data, split the streaming media data through a first operator network corresponding to the first user identification card and a second operator network corresponding to the second user identification card, and present the split streaming media data to the user after being combined, thereby implementing service acceleration.

4. The mobile terminal 100 may achieve the purpose of data service optimization during the data service process.

The transmission of uplink/downlink network data based on the second subscriber identity card will be described below.

Taking the example that a user downloads a movie in the background through a first operator network corresponding to a first subscriber identity card while browsing a web page in the foreground through a second operator network corresponding to a second subscriber identity card when using the mobile terminal 100, in a specific implementation, the movie downloading service is carried by the first application processing module 101 through a connection between the first modem processing module 102 directly connected thereto and the first operator network, and the web page browsing service is carried by the first application processing module 101 through a connection between the second modem processing module 202 transparently connected thereto and the second operator network. When receiving downlink network data from the second operator network (e.g. picture data returned by the operator network according to a picture acquisition request triggered by a user based on a browser) by the second modem processing module 202 (based on data interaction between the second radio frequency module 203 connected thereto and the second operator network), the second modem processing module transmits the downlink network data to the second application processing module 201 through a serial connection channel between the second modem processing module and the second application processing module 201, the second application processing module 201 does not perform any processing on the downlink network data after receiving the downlink network data, and directly transmits the downlink network data to the first application processing module 101, and the first application processing module 101 presents the downlink network data to the user through a corresponding application program operated by the first application processing module 101 after receiving the downlink network data, for example, a picture returned by the operator network is displayed by the browser application on the screen of the mobile terminal 100 for viewing by the user.

Taking the example that a user downloads a movie in the background through a first operator network corresponding to a first subscriber identity card while browsing a web page in the foreground through a second operator network corresponding to a second subscriber identity card when using the mobile terminal 100, in a specific implementation, the movie downloading service is carried by the first application processing module 101 through a connection between the first modem processing module 102 directly connected thereto and the first operator network, and the web page browsing service is carried by the first application processing module 101 through a connection between the second modem processing module 202 transparently connected thereto and the second operator network. When receiving uplink network data based on a second subscriber identity card (for example, a user uploads a picture through a browser application), the first application processing module 101 transmits the received uplink network data to the second application processing module 201, after receiving the uplink network data, the second application processing module 201 performs no processing on the uplink network data, and directly transmits the uplink network data to the second modem processing module 202 through a serial connection channel between the second application processing module 201 and the second modem processing module 202, and the second modem processing module 202 (based on data interaction between the second radio frequency module 203 connected thereto and a second operator network) transmits the received uplink network data to the second operator network.

In order to further expand the communication function of the mobile terminal, in this embodiment, the first application unit 01 and the second application unit 02 of the mobile terminal provide corresponding Wi-Fi application operation interfaces, so that a user can perform corresponding control and operation through the Wi-Fi application operation interfaces. For example, the first application unit 01 and the second application unit 02 may control operations such as connection/disconnection of the first Wi-Fi unit 40 and the second Wi-Fi unit 50 through the service unit 30, respectively. The first Wi-Fi unit 40 and the second Wi-Fi unit 50 respectively process the instructions issued by the first application unit 01 and the second application unit 02, the connection state information of the Wi-Fi hotspots, and the like.

When a user needs to connect the mobile terminal to a Wi-Fi hotspot to perform operations such as surfing the internet, the user can select a certain Wi-Fi hotspot to connect through a Wi-Fi application operation interface corresponding to the first application unit 01 or a Wi-Fi application operation interface corresponding to the second application unit 02, and when receiving a Wi-Fi connection operation triggered by the user, the first application unit 01 or the second application unit 02 triggers a corresponding connection instruction and sends the connection instruction to the service unit 30. For example, when the user triggers a Wi-Fi connection operation based on the Wi-Fi application operation interface corresponding to the first application unit 01, and the first application unit 01 receives the Wi-Fi connection operation, a connection instruction is triggered, and the connection instruction is issued to the service unit 30.

When the service unit 30 receives the connection instruction, the service unit 30 determines whether the connection instruction is from the first Wi-Fi unit 40 or the second Wi-Fi unit 50, that is, whether the user triggers the Wi-Fi connection operation based on the first application unit 01 or triggers the Wi-Fi connection operation based on the second application unit 02. Specifically, when the user triggers Wi-Fi connection operation based on a Wi-Fi application operation interface corresponding to the first application unit 01 and the first application unit 01 sends a connection instruction to the service unit 30, the service unit 30 determines that the connection instruction corresponds to the first Wi-Fi unit 40; when the user triggers Wi-Fi connection operation based on the Wi-Fi application operation interface corresponding to the second application unit 02 and the second application unit 02 sends a connection instruction to the service unit 30, the service unit 30 determines that the connection instruction corresponds to the second Wi-Fi unit 50. When the service unit 30 determines that the connection instruction corresponds to the first Wi-Fi unit 40, the service unit 30 sends the connection instruction to the first Wi-Fi unit 40; when the service unit 30 determines that the connection instruction corresponds to the second Wi-Fi unit 50, the service unit 30 transmits the connection instruction to the second Wi-Fi unit 50.

Further, in this embodiment, the first Wi-Fi unit 40 includes a first frame subunit 411, a first protocol subunit 412, and a first Wi-Fi chip 42, wherein,

the first framework subunit 411 is configured to receive a connection instruction issued by the service unit 30 and issue the connection instruction to the first protocol subunit 412;

the first protocol subunit 412 is configured to issue the connection instruction and the corresponding protocol to the first Wi-Fi chip 42;

the first Wi-Fi chip 42 is configured to perform air interface interaction with a corresponding hotspot based on the received connection instruction and the protocol, and establish an air interface connection with the corresponding hotspot after the air interface interaction is completed;

the second Wi-Fi unit 50 includes a second frame subunit 511, a second protocol subunit 512, and a second Wi-Fi chip 52, wherein,

the second framework subunit 511 is configured to receive the connection instruction issued by the service unit 30 and issue the connection instruction to the second protocol subunit 512;

the second protocol subunit 512 is configured to issue the connection instruction and the corresponding protocol to the second Wi-Fi chip 52;

the second Wi-Fi chip 52 is configured to perform air interface interaction with the corresponding hotspot based on the received connection instruction and the protocol, and establish an air interface connection with the corresponding hotspot after the air interface interaction is completed.

It should be noted that the first Wi-Fi unit 40 further includes a first driver sub-module 413, and the first protocol sub-unit 412 is specifically configured to issue the connection instruction and the corresponding protocol to the first Wi-Fi chip 42 based on a communication port between the first driver sub-module 413 and the first Wi-Fi chip 42;

the second Wi-Fi unit 50 further includes a second driver sub-module 513, and the second protocol sub-unit 512 is specifically configured to issue the connection instruction and the corresponding protocol to the second Wi-Fi chip 52 based on a communication port between the second driver sub-module 513 and the second Wi-Fi chip 52.

Further, in this embodiment, after the first Wi-Fi chip 42 or the second Wi-Fi chip 52 establishes an air interface connection with the corresponding hotspot, the first protocol subunit 412 or the second protocol subunit 512 correspondingly reports second indication information to the first framework subunit 411 or the second framework subunit 511;

the first framework subunit 411 or the second framework subunit 511 starts a corresponding DHCP (dynamic Host Configuration protocol) service based on the second indication information to perform a DHCP negotiation, so as to obtain an IP address after the negotiation is successful, where the performed DHCP negotiation may include a fast DHCP negotiation and a complete DHCP negotiation.

The first framework subunit 411 or the second framework subunit 511 is further configured to report the first indication information to the service unit 30 after obtaining the IP address.

It should be noted that, in this embodiment, a single data access routing configuration and a double data access routing configuration are preset. When receiving the first indication information reported by the first framework subunit 411 or the second framework subunit 511, the service unit 30 loads a routing configuration according to the connection states of the first Wi-Fi unit 40 and the second Wi-Fi unit 50, where,

It is easily understood that, when the first Wi-Fi unit 40 and the second Wi-Fi unit 50 both establish an open connection, and after the service unit 30 loads the preset dual data access routing configuration, the user may simultaneously access the same network through the first Wi-Fi unit 40 and the second Wi-Fi unit 50, or respectively access different networks through the first Wi-Fi unit 40 and the second Wi-Fi unit 50, for example, respectively access an extranet and an office network, an internet network and a printer, and the like.

Further, when the first Wi-Fi unit 40 and the second Wi-Fi unit 50 perform data communication at the same time, for example, when the first Wi-Fi unit 40 and the second Wi-Fi unit 50 access the same network at the same time, the service unit 30 may further perform operations of controlling bandwidth allocation of the first Wi-Fi unit 40 and the second Wi-Fi unit 50. For example, the first Wi-Fi unit 40 and the second Wi-Fi unit 50 are allocated with respective bandwidths according to respective rules such as an equal division or a preset ratio.

Moreover, as the service unit 30 can interact with both the first Wi-Fi unit 40 and the second Wi-Fi unit 50, redundancy caused by independently operating two Wi-Fi modules is avoided, the flow of data communication is simplified, and the data communication efficiency is improved.

Further, in this embodiment, in order to facilitate a user to know a connection state of the mobile terminal in real time, in this embodiment, the first Wi-Fi unit 40 or the second Wi-Fi unit 50 is further configured to report connection state information of establishing an air interface connection to the service unit 30 in real time in a process of establishing the air interface connection, so that the service unit 30 correspondingly reports the received connection state information to the first application unit 01 or the second application unit 02 for display, so as to prompt the user that the user is in connection.

Further, in this embodiment, the service unit 30 is further configured to correspondingly report the third indication information of successful connection to the first application unit 01 or the second application unit 02 issuing the connection instruction for display after the loading of the route configuration is completed.

After completing the loading of the routing configuration, the service unit 30 correspondingly reports the third indication information of the successful connection to the first application unit 01 or the second application unit 02 which issues the connection instruction for displaying, for example, if the connection instruction received by the service unit 30 is from the first application unit 01, the third indication information of the successful connection is reported to the first application unit 01 and displayed by the first application unit 01; for another example, if the connection instruction received by the service unit 30 is from the second application unit 02, the third indication information of successful connection is reported to the second application unit 02 and displayed by the second application unit 02.
