Detailed Description

The embodiment of the invention provides a method for supporting an access node to authenticate Wi-Fi connection in a wireless terminal, the access node and a storage medium, which are used for realizing intelligent and safe connection without inputting passwords manually even if the wireless terminal is not connected with other encryption networks.

The embodiments based on the present invention should fall into the protection scope of the present invention.

In the prior art, there is also a problem that each Wi-Fi needs to remember a password. Confusion is avoided if all Wi-Fi of the AP are set to the same password, but this presents another problem where one network is open to other users, but another network is only to family private members, and is easily accessible to other users if the same password is used.

In the embodiment of the application, the wireless terminal supports Wi-Fi linking. And may also be referred to as User Equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, User terminal, wireless communication device, User agent, or User device, etc.

Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

The method and the device utilize an encryption connection link established by the wireless terminal and the AP to transmit the SSID and the password of other networks of the AP by using a specific message, or transmit the SSID and the password of the network belonging to the same network subset AP with the AP. And after acquiring the specific information, the wireless terminal stores the specific information into a local Wi-Fi configuration file, when other Wi-Fi networks connected with the AP or networks belonging to the same network subset AP with the AP are connected, the Wi-Fi configuration file is inquired, and if the corresponding SSID and the password are inquired, the process of inputting the password is not needed, and the wireless terminal is directly connected with other Wi-Fi networks.

The technical solution of the present application is further described below by way of examples.

Example 1: the wireless terminal acquires the configuration information of the second Wi-Fi through the access node, and the configuration information is actively requested by the wireless terminal to the access node. The access node supports at least two Wi-Fi connections.

As shown in fig. 2, a schematic diagram of an embodiment of a method for supporting an access node in a wireless terminal to authenticate a Wi-Fi connection in the embodiment of the present application may include:

201. the wireless terminal establishes a first Wi-Fi connection with the access node.

202. In the case that the first Wi-Fi connection is an encrypted connection, and/or the wireless terminal supports multiple Wi-Fi connections, the wireless terminal sends a request to the access node, the request requesting configuration information for the second Wi-Fi.

Optionally, the wireless terminal may first determine whether a first Wi-Fi connection established with the access node is an encrypted connection, and then determine whether the wireless terminal supports multiple Wi-Fi connections when the first Wi-Fi connection is the encrypted connection, and send a request to the access node when the wireless terminal supports multiple Wi-Fi connections.

Optionally, the wireless terminal may first determine whether the wireless terminal supports multiple Wi-Fi connections, and then determine whether a first Wi-Fi connection established with the access node is an encrypted connection when the wireless terminal supports multiple Wi-Fi connections, and send a request to the access node when the first Wi-Fi connection is an encrypted connection.

Optionally, the wireless terminal may determine whether a first Wi-Fi connection established with the access node is an encrypted connection, and send a request to the access node when the first Wi-Fi connection is the encrypted connection.

Optionally, the wireless terminal may first determine whether the wireless terminal supports multiple Wi-Fi connections, and in a case that the wireless terminal supports multiple Wi-Fi connections, the wireless terminal sends a request to the access node.

Illustratively, the wireless terminal may send a request to the access node based on the first Wi-Fi connection being encrypted; the access node receives a request sent by the wireless terminal. The request may be a specific request frame for requesting configuration information of the second Wi-Fi. The number of the second Wi-Fi devices may be one or more, and is not limited. The wireless terminal can judge whether to support multi-Wi-Fi connection capability according to the self capability, and the multi-Wi-Fi connection capability can be in a Wi-Fi multi-band form or a multi-frequency concurrent form (namely, a plurality of Wi-Fi are connected at the same time).

It will be appreciated that the cryptographic security of the current first Wi-Fi connection needs to be confirmed at both the wireless terminal and the access node end because of the SSID related cryptographic interaction between the wireless terminal and the access node.

Optionally, the configuration information includes a service set identifier and a password.

Optionally, the second Wi-Fi is another Wi-Fi of the access node, or the second Wi-Fi is a Wi-Fi of another access node of the same network subset as the access node.

203. And the access node sends configuration information of a second Wi-Fi to the wireless terminal through the first Wi-Fi connection under the condition that the first Wi-Fi connection is connected through encryption and the wireless terminal supports multiple Wi-Fi connections according to the request.

Optionally, the access node acquires the configuration information of the second Wi-Fi and sends the configuration information of the second Wi-Fi to the wireless terminal according to the request, when the first Wi-Fi connection is connected through encryption and the wireless terminal supports multiple Wi-Fi connections.

Optionally, the second Wi-Fi is a public type Wi-Fi. Since the public type Wi-Fi is generally low in security and privacy, the SSID and password can be acquired by other Wi-Fi.

Optionally, the access node may first determine whether a first Wi-Fi connection established with the wireless terminal is an encrypted connection, and then determine whether the wireless terminal supports multiple Wi-Fi connections if the first Wi-Fi connection is the encrypted connection, and acquire configuration information of a second Wi-Fi connection if the first Wi-Fi connection supports multiple Wi-Fi connections.

Optionally, the access node may first determine whether the wireless terminal supports multiple Wi-Fi connections, determine whether a first Wi-Fi connection established with the wireless terminal is an encrypted connection if the wireless terminal supports multiple Wi-Fi connections, and acquire configuration information of a second Wi-Fi connection if the first Wi-Fi connection is an encrypted connection.

Optionally, the access node may determine whether the wireless terminal supports multiple Wi-Fi connections, and acquire configuration information of a second Wi-Fi network when the wireless terminal supports multiple Wi-Fi connections.

Optionally, the access node may determine whether the first Wi-Fi connection established with the wireless terminal is an encrypted connection, and acquire configuration information of the second Wi-Fi in the case of the encrypted connection.

Optionally, the access node further confirms the Wi-Fi that allows another Wi-Fi to acquire the SSID and the password when determining that there is a second Wi-Fi, and further acquires the SSID and the password of the second Wi-Fi.

It will be appreciated that the wireless terminal receives configuration information for a second Wi-Fi from the access node over the first Wi-Fi connection.

Optionally, the receiving, from the access node through the first Wi-Fi connection, configuration information of a second Wi-Fi may include:

the wireless terminal judges whether the first Wi-Fi connection is encrypted connection, and receives configuration information of a second Wi-Fi from the access node through the first Wi-Fi connection under the condition that the first Wi-Fi connection is encrypted connection; and/or the presence of a gas in the gas,

the wireless terminal judges whether the wireless terminal supports multi-Wi-Fi connection, and receives configuration information of a second Wi-Fi from the access node through the first Wi-Fi connection under the condition that the wireless terminal supports multi-Wi-Fi connection.

Optionally, within a second predetermined time, if the wireless terminal does not receive the configuration information of the second Wi-Fi, the request is sent to the access node again.

Optionally, the access node sends a response to the wireless terminal according to the request; the wireless terminal receives a response sent by the access node according to the request; the wireless terminal resending the request to the access node without recognizing the response; the access node re-receives the request from the wireless terminal.

Each Wi-Fi network on an AP may set whether it allows access to passwords in this manner. Fig. 3 is a schematic diagram illustrating password interaction permission settings of different types of networks of an AP in the embodiment of the present application. In the illustration of fig. 3, the arrow direction indicates the direction of SSID and password transmission. The SSID and the password of the public wireless fidelity (public Wi-Fi) can be acquired by other public Wi-Fi and private wireless fidelity (private Wi-Fi) in the mode, the SSID and the password of the private Wi-Fi cannot be acquired by other public Wi-Fi, and the acquisition permission among different private Wi-Fi can be flexibly set.

Optionally, the wireless terminal receives the service set identifier and the password of the second Wi-Fi sent by the access node.

An example of an exemplary format of an acknowledgement frame carrying a service set identifier and a password of a second Wi-Fi network is shown, where an Information Element (IE) 1 indicates that the type of the frame is an acknowledgement frame of Service Set Identifier (SSID) and password interaction, and then an SSID and a corresponding password of each Wi-Fi network. As shown in table 1 below:

TABLE 1

It should be noted that, if the access node determines that the first Wi-Fi connection currently established with the wireless terminal is not an encrypted connection, a response including a reject frame may be replied to the wireless terminal; or, if the access node judges that no other Wi-Fi exists on the access node, a response including a rejection frame may be replied to the wireless terminal; alternatively, if the access node determines that there is no Wi-Fi that allows another Wi-Fi to obtain the SSID and password, a response including a reject frame may be replied to the wireless terminal. If the wireless terminal receives a response including a reject frame, the flow ends.

It can be understood that, if the wireless terminal sends a request to the access node, and if the access node receives a response including an acknowledgement frame, the configuration information of the second Wi-Fi in the acknowledgement frame is written into the local configuration file; if a response including the rejection frame replied by the access node is received, ending the process; if no response or no response is received within a preset time duration, the wireless terminal may implement a frame retransmission policy, i.e., resend the request to the access node.

204. The wireless terminal stores the configuration information in a local configuration file.

It is to be appreciated that the wireless terminal stores the configuration information for the second Wi-Fi in a local configuration file. Optionally, the configuration information of the second Wi-Fi may include a service set identifier and a password of the second Wi-Fi.

It is understood that the local configuration file may be a local Wi-Fi configuration file. Step 204 is an optional step.

205. And the wireless terminal establishes the second Wi-Fi connection with the access node according to the configuration information.

Optionally, the establishing the second Wi-Fi connection with the access node according to the configuration information may include: and the wireless terminal establishes the second Wi-Fi connection with the access node according to the configuration information in the local configuration file.

Optionally, if the configuration information of the second Wi-Fi is queried in the local configuration file, the wireless terminal establishes the second Wi-Fi connection with the access node.

Optionally, the establishing, by the wireless terminal, the second Wi-Fi connection with the access node may include:

(1) maintaining a connection with the first Wi-Fi and establishing the second Wi-Fi connection with the access node; i.e., a wireless terminal may connect two or more Wi-Fi simultaneously. Or the like, or, alternatively,

(2) and disconnecting the connection with the first Wi-Fi and establishing the second Wi-Fi connection with the access node. I.e., the wireless terminal switches from connecting a first Wi-Fi to connecting a second Wi-Fi.

It should be noted that the wireless terminal directly establishes the second Wi-Fi connection with the access node, which means that the wireless terminal does not need to input a password, and does not need to respond to the operation of inputting the password by the user, and can directly establish the second Wi-Fi connection with the access node.

Optionally, the method further includes: the wireless terminal receives second Wi-Fi updated configuration information from the access node via the first Wi-Fi connection, the second Wi-Fi updated configuration information including an updated service set identifier, and/or an updated password.

In the embodiment of the application, a wireless terminal establishes a first Wi-Fi connection with an access node; and under the condition that the first Wi-Fi connection is connected through encryption and the wireless terminal supports second Wi-Fi connection, if a service set identifier and a password of the second Wi-Fi are inquired in a local configuration file, the wireless terminal directly establishes the second Wi-Fi connection with an access node, and the second Wi-Fi is the Wi-Fi which is not connected with the wireless terminal. Namely, after the first encryption network is normally established between the wireless terminal and the access node, other encryption networks are connected, even if the wireless terminal and the access node are not connected before, the password does not need to be input manually, and intelligent and safe connection is realized. Optionally, the SSID and password of other Wi-Fi networks between the two devices are interacted by using an encryption network already established between the wireless terminal and the AP. Therefore, after the wireless terminal and the AP normally establish the first encryption network, other encryption networks are connected, even if the wireless terminal and the AP are not connected before, the password does not need to be manually input, the wireless terminal looks like being connected with the network, and intelligent and safe connection is realized.

In the embodiment of the application, when a Wi-Fi of a wireless terminal and an Access Point (AP) establishes a connection successfully and then establishes a connection with other Wi-Fi of the AP, even if the connection is the first time and an authentication encryption process exists, a user does not need to manually input a password, and the wireless terminal can be directly connected with other Wi-Fi.

Example 2: and the wireless terminal acquires the configuration information of the second Wi-Fi through the access node, and the configuration information is actively sent to the wireless terminal by the access node. The access node supports at least two Wi-Fi connections.

As shown in fig. 4, a schematic diagram of another embodiment of a method for supporting an access node in a wireless terminal to authenticate a Wi-Fi connection in the embodiment of the present application may include:

401. the wireless terminal establishes a first Wi-Fi connection with the access node.

402. And sending configuration information of a second Wi-Fi to the wireless terminal through the first Wi-Fi connection under the condition that the first Wi-Fi connection is connected through encryption and/or the wireless terminal supports multiple Wi-Fi connections.

Optionally, the configuration information of the second Wi-Fi is obtained and sent to the wireless terminal when the first Wi-Fi connection is connected through encryption and/or the wireless terminal supports multiple Wi-Fi connections.

Optionally, the access node may first determine whether a first Wi-Fi connection established with the wireless terminal is an encrypted connection, and then determine whether the wireless terminal supports multiple Wi-Fi connections when the first Wi-Fi connection is the encrypted connection, and acquire configuration information of a second Wi-Fi connection when the multiple Wi-Fi connections are supported.

Optionally, the access node determines whether the wireless terminal supports multiple Wi-Fi connections, determines whether a first Wi-Fi connection established with the wireless terminal is an encrypted connection if the wireless terminal supports multiple Wi-Fi connections, and acquires configuration information of a second Wi-Fi connection if the first Wi-Fi connection is an encrypted connection.

It will be appreciated that the wireless terminal receives configuration information for a second Wi-Fi from the access node over the first Wi-Fi connection. Optionally, after receiving the service set identifier and the password of the second Wi-Fi sent by the access node, the wireless terminal may reply an Acknowledgement (ACK) to the access node according to a common frame.

Optionally, within a first predetermined time, if the wireless terminal does not receive the configuration information of the second Wi-Fi, the request is sent to the access node.

That is, in the embodiment where the access node actively sends the configuration information of the second Wi-Fi to the wireless terminal, if the wireless terminal does not receive the configuration information of the second Wi-Fi sent by the access node within the first predetermined time period, the wireless terminal may initiate a request to the access node to actively request the configuration information of the second Wi-Fi. It can be understood that, if the wireless terminal sends a request to the access node, and if the access node receives a response including an acknowledgement frame, the configuration information of the second Wi-Fi in the acknowledgement frame is written into the local configuration file; if a response including the rejection frame replied by the access node is received, ending the process; if no response or no recognized response is received within the second predetermined time period, the wireless terminal may implement a frame retransmission policy, i.e., resend the request to the access node.

Optionally, when it is detected that the second Wi-Fi configuration information is updated, the access node acquires the updated configuration information of the second Wi-Fi; the access node sends second Wi-Fi updated configuration information to the wireless terminal through the first Wi-Fi connection; the second Wi-Fi updated configuration information includes the second Wi-Fi updated service set identifier, and/or an updated password. That is, the service set identifier of the second Wi-Fi may be updated, and the password may also be updated, and in case of update, the access node may also actively send the updated service set identifier and/or the updated password to the wireless terminal, and notify the wireless terminal to update its SSID and password in time.

An example of a specific frame format carrying a service set identifier and a password of a second Wi-Fi is illustrated, where an Information Element (IE) 2 indicates that the type of the frame is a specific frame of a Service Set Identifier (SSID) and password interaction, and then an SSID and a corresponding password of each Wi-Fi network. As shown in table 2 below:

TABLE 2

403. The wireless terminal stores the configuration information in a local configuration file.

404. And the wireless terminal establishes the second Wi-Fi connection with the access node according to the configuration information.

Optionally, steps 403 and 404 may refer to the description of steps 204 and 205 in the embodiment shown in fig. 3, and are not described herein again.

In the embodiment shown in fig. 2, the wireless terminal mainly initiates the request, the AP responds, and then the wireless terminal performs different operations according to different results. However, the wireless terminal requests, the AP replies, and then the wireless terminal performs different operations according to different reply types, which is a somewhat cumbersome process. The method is only carried out at the stage of establishing connection of one network, after SSID and password of other networks are obtained, if the obtained SSID or password of the network is changed, the wireless terminal cannot know the SSID or password in time, and at the moment, if the wireless terminal is connected with the network with the modified SSID or password of the AP, the password still needs to be input again. In the embodiment of the application, after the wireless terminal and the AP establish the first Wi-Fi connection, the AP actively sends out a frame carrying SSIDs and passwords of other Wi-Fi, and the wireless terminal replies ACK according to the common frame without further processing if the function of the scheme is not supported. In addition, when the SSID or password of the Wi-Fi connected with the AP and the wireless terminal is not modified, the specific frame can be triggered to be sent on the Wi-Fi connected with the AP and the wireless terminal, and the wireless terminal is informed to update the SSID and the password in time.

The application has the innovation point that SSIDs and passwords of other networks of the AP are obtained interactively by using the encrypted connection link established by the wireless terminal and the AP, so that the process that the same wireless terminal needs to input the passwords repeatedly when being connected with different networks of the same AP is omitted. For the wireless terminal, the wireless terminal can be in different frequency bands or in a multi-frequency concurrent mode; for an AP, it is its different network SSID. The corresponding interactive frame definition may include a request frame and a reply frame. The other key point is the setting of network SSID and password acquisition authority at the AP side.

The technical scheme of the application needs to support the function of the wireless terminal and the AP which support multiple frequencies (including concurrency), and the functions can be respectively demonstrated.

Establishing a first connection with a multi-frequency AP to be proved by using a wireless terminal supporting the function, then initiating connection with a second network by the wireless terminal, and observing whether the connection is successful without inputting a password; and establishing a first connection with a multi-frequency wireless terminal to be proved by using the AP supporting the function, and then initiating connection with a second network by the wireless terminal to observe whether the direct connection is successful without inputting a password.

For some products, a similar technical scheme can be used, but the frame type is modified, so that the product cannot correctly analyze the frame, a wireless terminal and an AP using the same manufacturer scheme can be connected, and whether password connection is not required to be input by other networks after the password connection is input by the first network is observed. And the technical scheme can also be used for preliminarily judging whether the product to be proved uses the data such as the product introduction description and the like.

Referring to fig. 7, the handset includes: radio Frequency (RF) circuit 710, memory 720, input unit 730, display unit 740, sensor 750, audio circuit 760, wireless fidelity (Wi-Fi) module 770, processor 780, and power supply 790. Those skilled in the art will appreciate that the handset configuration shown in fig. 7 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 7:

the RF circuit 710 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 780; in addition, the data for designing uplink is transmitted to the base station. In general, the RF circuit 710 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 710 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory 720 may be used to store software programs and modules, and the processor 780 may execute various functional applications and data processing of the cellular phone by operating the software programs and modules stored in the memory 720. The memory 720 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 720 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 730 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 730 may include a touch panel 731 and other input devices 732. The touch panel 731, also referred to as a touch screen, can collect touch operations of a user (e.g. operations of the user on or near the touch panel 731 by using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 731 may include two portions of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts it to touch point coordinates, and sends the touch point coordinates to the processor 780, and can receive and execute commands from the processor 780. In addition, the touch panel 731 may be implemented by various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 730 may include other input devices 732 in addition to the touch panel 731. In particular, other input devices 732 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 740 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The Display unit 740 may include a Display panel 741, and optionally, the Display panel 741 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 731 can cover the display panel 741, and when the touch panel 731 detects a touch operation on or near the touch panel 731, the touch operation is transmitted to the processor 780 to determine the type of the touch event, and then the processor 780 provides a corresponding visual output on the display panel 741 according to the type of the touch event. Although the touch panel 731 and the display panel 741 are two independent components in fig. 7 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 731 and the display panel 741 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 750, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 741 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 741 and/or a backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuitry 760, speaker 761, and microphone 762 may provide an audio interface between a user and a cell phone. The audio circuit 760 can transmit the electrical signal converted from the received audio data to the speaker 761, and the electrical signal is converted into a sound signal by the speaker 761 and output; on the other hand, the microphone 762 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 760, and then processes the audio data output processor 780, and then transmits the audio data to, for example, another cellular phone through the RF circuit 710, or outputs the audio data to the memory 720 for further processing.

Wi-Fi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through a Wi-Fi module 770, and provides wireless broadband internet access for the user. Although fig. 7 shows the Wi-Fi module 770, it is understood that it does not belong to the essential constitution of the handset and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 780 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 720 and calling data stored in the memory 720, thereby integrally monitoring the mobile phone. Alternatively, processor 780 may include one or more processing units; preferably, the processor 780 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 780.

The handset also includes a power supply 790 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 780 via a power management system, so that the power management system may be used to manage charging, discharging, and power consumption.

Although not shown, the mobile phone may further include a camera, a bluetooth module, etc., which will not be described herein.
