[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] In actual applications, due to the closed nature of elevators, the wireless signal coverage of elevators is mainly completed by indoor construction; since the wireless signal coverage antennas of elevators are basically passive devices, invisible faults cannot be discovered in time through network management. If there is an invisible fault problem in the elevator signal coverage, it will not only affect the mobile user's perception of use in the elevator, but also fail to call for help when the elevator encounters a fault, which is likely to cause serious safety problems. At present, the invisible fault problem of elevator signal coverage is mainly discovered by the front-line network optimization and equipment maintenance personnel through on-site signal testing, handling user complaints and combining the network management status of the main equipment; this method has the problems of late discovery, long time consumption, high labor cost and affecting user perception before knowing. Therefore, it is particularly important to use certain technologies to quickly determine whether there is an invisible fault in the elevator's 4G coverage.

[0051] In order to identify whether there is an invisible fault in the 4G coverage of the elevator network, the embodiment of the present invention uses the signal changes of mobile users in the elevator to determine whether there is an invisible fault in the 4G coverage of the elevator, thereby quickly discovering elevators with coverage problems, improving the wireless network operation efficiency and enhancing the mobile user's usage perception.

[0052] In the specific implementation, the embodiment of the present invention mainly provides a method for discovering hidden faults in the elevator 4G coverage based on the user dimension. Since the present invention is to determine whether there is a hidden fault in the elevator 4G coverage, it is first necessary to verify the status of the indoor base station main device through the network management. When the main device is normal, the 4G signal strength of the indoor cell of the mobile user in the elevator is identified, thereby providing a basis for determining whether there is a hidden fault in the elevator signal 4G coverage.

[0053] First, mobile users who have the operator's home broadband service and AGPS function can be selected as preliminary selected users to identify and calculate the approximate time when mobile users enter and leave the elevator, thereby obtaining the signal strength and frequency of mobile users accessing the elevator's 4G coverage area.

[0054] Next, the pure indoor coverage plan can be identified through the base station planning plan, and elevators with outdoor entrances can be selected as the initial selection elevators to eliminate interference from garage indoor signals and indoor signal coverage outdoors.

[0055] Then, the preliminary selected users and the preliminary selected elevators are matched to identify the resident users in the preliminary selected elevators, and the preliminary selected elevators with a certain number of resident users or more are output as target elevators. The target elevators are elevators that can identify invisible faults in 4G coverage.

[0056] Finally, by introducing the discrete probability function of coverage, we can judge whether there is an invisible fault in the elevator 4G coverage through expectation.

[0057] The embodiments of the present invention can be used to quickly discover whether there are invisible faults in the elevator 4G coverage, which is convenient for rectifying the elevator coverage problem and helps to improve the network operation efficiency and the mobile user perception protection capability to a certain extent.

[0058] Reference Figure 1 , shows a flowchart of the steps of an elevator fault detection method provided in an embodiment of the present invention, which may specifically include the following steps:

[0059] Step 101, determining a user service type, and determining a user whose user service type is an assisted global positioning system function as a preliminary selected user;

[0060] Step 102, obtaining elevator construction information, determining through the elevator construction information that the construction location meets the preset conditions and preliminarily selecting an elevator;

[0061] Step 103, determining a resident user for the initially selected elevator from the initially selected users;

[0062] Step 104, when the number of resident users is greater than a preset threshold, the initially selected elevator is determined as a target elevator;

[0063] Step 105: Acquire signal distribution information of resident users of the target elevator, and generate a fault detection result for the target elevator based on the signal distribution information.

[0064] AGPS, the full name of which is Assisted Global Positioning System, is a technology that accelerates GPS positioning through network assistance.

[0065] How AGPS works:

[0066] Using network assistance information: AGPS devices will connect to an assistance server through the mobile network and obtain some pre-calculated satellite position information (ephemeris) and other data from the server.

[0067] Speed ​​up the positioning process: These pre-acquired data can help the GPS receiver find satellite signals faster and shorten the positioning time.

[0068] Improved positioning accuracy: In some cases, AGPS can also improve the accuracy of positioning, especially in urban environments or places where GPS signals are weak.

[0069] Advantages of AGPS:

[0070] Fast positioning speed: Compared with traditional GPS, AGPS can obtain positioning results faster.

[0071] Improve positioning success rate: In an environment with weak signals, AGPS can increase the probability of successful positioning.

[0072] Reduce power consumption: AGPS can reduce the power consumption of the device due to the shortened positioning time.

[0073] Application of AGPS

[0074] Smartphones: Most smartphones have built-in AGPS functions to provide services such as map navigation and location sharing.

[0075] In-car navigation system: In-car navigation systems also generally use AGPS technology to improve navigation accuracy and response speed.

[0076] IoT devices: Many IoT devices, such as smart watches and sports bracelets, also use AGPS for positioning.

[0077] Simply put, AGPS is like adding a "booster" to GPS, allowing it to find your location faster and more accurately.

[0078] AGPS accelerates the GPS positioning process through network assistance, improves the efficiency and accuracy of positioning, and has been widely used in daily life in the embodiments of the present invention, providing a more convenient location service for the embodiments of the present invention.

[0079] In a specific implementation, an embodiment of the present invention can select mobile users whose user service type is to apply for home broadband service and have assisted global positioning system AGPS function as preliminary selected users, so as to identify and calculate the approximate time when the mobile user enters and leaves the elevator, thereby obtaining the signal strength and frequency of the mobile user accessing the elevator 4G coverage area.

[0080] Next, the elevator construction information can be obtained. For example, for the base station planning plan for the elevator, the pure indoor coverage plan can be identified through the elevator construction information, and the elevators with outdoor entrances are screened out as the initial selection elevators to eliminate interference from garage indoor signals and indoor signals covering outdoor areas.

[0081] Then, the preliminary selected users and the preliminary selected elevators are matched, the resident users existing in the preliminary selected elevators are identified, and the preliminary selected elevators with a certain number of resident users are output as target elevators, and the target elevators are elevators capable of identifying 4G coverage invisible faults. For example, in order to reduce the impact of very individual resident users, this article considers that the number of resident users needs to be greater than or equal to 10.

[0082] Finally, by obtaining the signal distribution information of the resident users of the target elevator and generating the fault detection result for the target elevator based on the signal distribution information, it is possible to determine whether there is any invisible fault in the elevator 4G coverage.

[0083] According to an embodiment of the present invention, by determining the user service type, a user whose user service type is an assisted global positioning system function is determined as a preliminarily selected user; elevator construction information is obtained, and an elevator is preliminarily selected by determining that the construction location meets preset conditions through the elevator construction information; resident users for the preliminarily selected elevator are determined from the preliminarily selected users; when the number of the resident users is greater than a preset threshold, the preliminarily selected elevator is determined as a target elevator; signal distribution information of the resident users of the target elevator is obtained, and a fault detection result for the target elevator is generated based on the signal distribution information, so as to quickly discover elevators with coverage problems, improve wireless network operation efficiency, and enhance mobile user usage perception.

[0084] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0085] refer to Figure 2 , Figure 2 is a flow chart of an elevator fault detection method provided in an embodiment of the present invention;

[0086] In an optional embodiment of the present invention, the step of determining the user service type and determining the user whose user service type is an assisted global positioning system function as the preliminary selected user includes:

[0087] Obtaining a measurement report sent by a user mobile terminal;

[0088] When it is determined through the latitude and longitude information in the measurement report that the user mobile terminal has the capability to report the position, determining that the user service type is an assisted global positioning system function;

[0089] The users whose user service types are assisted global positioning system functions are determined as preliminary selected users.

[0090] MR information, or Measurement Report, in the field of wireless communications, especially in mobile communication networks, refers to a report sent by the user equipment (UE, such as your mobile phone) to the base station. This report contains the UE's measurement data of the surrounding wireless network environment, such as signal strength, signal quality and other information.

[0091] The role of MR information:

[0092] Network optimization: By analyzing the MR information sent by the UE, the base station can understand the network coverage, interference, etc., so as to perform targeted network optimization and improve the user experience.

[0093] Switching decision: When the UE is moving, the base station will determine whether cell switching is required based on the MR information sent by the UE to ensure that the UE is always connected to the cell with the best signal.

[0094] Resource allocation: The base station can allocate more appropriate radio resources to the UE based on the UE's MR information, thereby improving system capacity and user experience.

[0095] MR information includes:

[0096] MR information contains a lot of measurement data, the most common ones include:

[0097] Serving cell measurement data:

[0098] Reference Signal Received Power (RSRP): reflects the strength of the serving cell signal.

[0099] Reference Signal Received Quality (RSRQ): reflects the quality of the serving cell signal, taking into account the impact of RSRP and interference.

[0100] Signal-to-noise ratio (SINR): reflects the ratio of signal to interference and is also an important indicator for measuring signal quality.

[0101] Neighboring cell measurement data:

[0102] RSRP, RSRQ and other information of neighboring cells.

[0103] Other measurement data:

[0104] Interference measurement data, frequency offset measurement data, and time advance measurement data;

[0105] MR information reporting method:

[0106] The UE can periodically report MR information to the base station, or trigger reporting when a specific event occurs, such as:

[0107] Periodic reporting: The UE sends MR information at a certain period so that the base station can understand the network status in real time.

[0108] Event-triggered reporting: When certain events occur, such as a sudden drop in signal strength or the discovery of a better neighboring cell, the UE will immediately report MR information to the base station.

[0109] MR information is a very important information in wireless communication networks. It carries the UE's perception of the wireless environment. By analyzing MR information, operators can better optimize the network and improve user experience.

[0110] In a specific implementation, in order to better serve users, the embodiment of the present invention can screen out potential target users in the following manner:

[0111] Broadband information verification: The embodiment of the present invention will check the user's account opening information to confirm whether the user is a local broadband user of the operator.

[0112] Location information verification: The embodiment of the present invention analyzes the measurement report (MR) data reported by the user's mobile terminal to determine whether it has the ability to report the latitude and longitude position.

[0113] Only users who meet both of the above conditions will be included in the preliminary selected user list of the embodiment of the present invention.

[0114] In this way, the embodiment of the present invention can more accurately target customer groups that are both broadband users and can provide location information, thereby laying a foundation for subsequent detection processes.

[0115] In an optional embodiment of the present invention, the step of obtaining elevator construction information, determining that the construction location meets the preset conditions through the elevator construction information, and preliminarily selecting an elevator comprises:

[0116] Get elevator construction information;

[0117] Elevators whose elevator entrances are outdoors are screened out through the elevator construction information, and the elevators are determined as preliminary selected elevators.

[0118] By analyzing the changes in the elevator 4G signal, the signal coverage in the elevator is accurately evaluated and potential invisible faults are found. In order to eliminate interference from other factors, the embodiment of the present invention can select a cell covered by a pure indoor distribution system (room distribution) and conduct an in-depth study on elevators with outdoor entrances.

[0119] This selection ensures:

[0120] Single signal source: Avoid the influence of outdoor base station signals on the signals inside the elevator, so as to more accurately evaluate the performance of the indoor distribution system.

[0121] Consistent environmental factors: Reduce the impact of outdoor environmental changes on signals and improve the reliability of research results.

[0122] In this way, more attention can be paid to signal problems inside the elevator, improving the efficiency of troubleshooting.

[0123] The embodiment of the present invention obtains elevator construction information; screens out elevators whose elevator entrances are outdoors through the elevator construction information, and determines the elevators as preliminary selected elevators; and can focus more on signal problems inside the elevator, thereby improving the efficiency of troubleshooting.

[0124] In an optional embodiment of the present invention, the step of determining the resident users for the initially selected elevator from the initially selected users comprises:

[0125] Determine the time when the latitude and longitude information is last reported before the initially selected user enters the target elevator as the elevator entry time;

[0126] Determine the time when the user mobile terminal of the initially selected user reports the latitude and longitude information for the first time after accessing the broadband as the time of leaving the elevator;

[0127] When the time interval between the time of leaving the elevator and the time of entering the elevator is greater than a preset interval range threshold, checking the historical Internet access record of the initially selected user for the initially selected elevator;

[0128] When it is determined through the historical Internet access records that the initially selected user meets the preset number of rides within a preset time period, the initially selected user is determined as a resident user of the initially selected elevator.

[0129] In order to accurately evaluate the 4G signal quality in the elevator, it is necessary to determine the time range of the user's elevator ride. By analyzing the user's reported location information and network access records, the time when the user entered and left the elevator can be roughly inferred.

[0130] The specific method is as follows:

[0131] Determine the building the user is in: Determine whether the user is near the building based on the latitude and longitude position reported by the user for the last time.

[0132] Determine whether the user has entered the elevator: If the location reported by the user is within 0-10 meters from the edge of the building, and the connected network cell is an outdoor coverage cell, it can be considered that the user may have entered the elevator.

[0133] Determining whether the user has left the elevator: When the user returns home and accesses the broadband network for the first time, it can be considered that the user has left the elevator.

[0134] In order to accurately evaluate the 4G signal quality in an elevator, the embodiment of the present invention can determine the specific time that the user takes the elevator. Considering that an indoor cell usually covers multiple buildings, the user's activity time in the elevator can be estimated in the following way:

[0135] The elevator entry time may be determined by determining the time when the latitude and longitude information is last reported before the initially selected user enters the target elevator as the elevator entry time.

[0136] For example, when the user last reports his location near a building (within 0-10 meters from the edge of the building) and the connected network cell is an outdoor coverage cell, it is considered that the user may have entered the elevator, so this time point can be used as the time of entering the elevator.

[0137] The time of leaving the elevator may be determined by determining the time when the latitude and longitude information is first reported after the mobile terminal of the initially selected user is connected to the broadband as the time of leaving the elevator.

[0138] For example, when the user returns home and accesses the broadband network for the first time, it is considered that the user has left the elevator, so this time point can be used as the time of leaving the elevator.

[0139] The user's activity time in the elevator is inferred by the time when the user last reported the location and first accessed the broadband. However, in practical applications, this method has a potential problem: if the user stays near the elevator for a while before returning home after leaving the elevator, the longitude and latitude information reported during this stay may be mistaken as the user's signal in the elevator. This will cause some signal data in the elevator to be missed, thus affecting the evaluation of the network coverage in the elevator.

[0140] In order to solve this problem, the embodiment of the present invention proposes a new method:

[0141] First, the time interval between the time when the user leaves the elevator and the time when the user enters the elevator is preliminarily determined by the above method, and the time interval between the two time points is determined, and a preset interval range threshold is pre-set. When the time interval between the time when the user leaves the elevator and the time when the user enters the elevator is greater than the preset interval range threshold, the time when the user leaves the elevator and enters the elevator is determined to be valid.

[0142] Exemplarily, the preset interval range threshold can be set to 3 minutes. If the time difference between the user's last reported longitude and latitude and the first time access to broadband (time interval) is greater than or equal to 3 minutes, the user's leaving the elevator time and entering the elevator time are determined to be valid. If the time difference between the user's last reported longitude and latitude and the first time access to broadband (time interval) is less than 3 minutes, then the reporting time is moved forward until the 3-minute time difference is met.

[0143] The reason is that it is considered that after the user leaves the elevator, it is unlikely that he will return to the elevator within 3 minutes, so the longitude and latitude reported 3 minutes ago are regarded as the last report of the user in the elevator.

[0144] The setting of the preset interval range threshold can be determined based on balancing accuracy and efficiency. If the time threshold is set too short, some valid signal data may be missed; if it is set too long, too much noise data may be introduced.

[0145] Through this method, the user's activity time in the elevator can be determined more accurately, thereby collecting signal strength data in the elevator more comprehensively, providing more reliable data support for evaluating the network coverage in the elevator.

[0146] After determining that the time when the user left the elevator and the time when he entered the elevator are valid, the historical Internet access records of the initially selected user for the initially selected elevator can be viewed;

[0147] When it is determined through historical online records that the initially selected user meets the preset number of rides within a preset time period, the initially selected user is determined as a resident user of the initially selected elevator;

[0148] Optionally, it also includes:

[0149] When the time interval between the elevator leaving time and the elevator entering time is greater than a preset interval range threshold, and it is determined that the preliminarily selected user meets the preset number of rides within the preset time period, and it is determined that the Internet access log for the preliminarily selected elevator does not exist, a preset reference signal receiving power is configured for the preliminarily selected elevator.

[0150] In a specific implementation, for a situation where there are multiple elevators in one building, the strategy implemented by the present invention is to make a unified evaluation of whether there are hidden 4G coverage failures in the multiple elevators.

[0151] The historical online records can be used to determine whether there is an online log of the user who initially selected the elevator.

[0152] For example, in order to exclude the influence of occasional users, this patent introduces a resident algorithm based on which it is defined as the existence of Internet access logs in the elevator 4G cell for four out of seven days, and the Internet access logs are identified using DPI data. The specific formula is as follows:

[0153]

[0154] i is 1 to 7 days. When the Internet log of this user appears on a certain day, n i 1 if yes, 0 otherwise.

[0155] n i Indicates whether a user has an Internet access log in the 4G cell of the elevator on the i-th day. If the user has an Internet access log on the i-th day, then n i is 1 if the value is set to true; otherwise, it is 0.

[0156] The algorithm represented by the above formula is actually used to identify permanent users. By counting the number of days in 7 days that a user has Internet access logs in the elevator's 4G cell, if the number of days is greater than or equal to 4, then the user is considered a permanent user of the elevator. The permanent user is identified by the permanent algorithm, thereby eliminating the impact of occasional abnormal users on the calculation results.

[0157] RSRP (Reference Signal Received Power) refers to the reference signal received power. In a wireless communication system, the base station will send some special signals (reference signals) to the user equipment. The user equipment can determine the current signal strength by measuring the power of these signals. The RSRP mean refers to the average value of all RSRP values ​​measured by the user equipment over a period of time.

[0158] The purpose of calculating the RSRP mean is to:

[0159] Reflects the cell coverage quality: The RSRP mean can reflect the average signal strength in the cell and is an important indicator for measuring the cell coverage quality.

[0160] Evaluating user experience: The higher the RSRP average value, the stronger the signal received by the user device and the better the user's Internet experience.

[0161] Optimize the network: By analyzing the average RSRP of different cells, operators can identify areas with weak signal coverage and optimize the network in a targeted manner.

[0162] By calculating the RSRP mean, we can understand the signal coverage in the cell, evaluate the user experience, and provide data support for network optimization.

[0163] Exemplarily, the preset reference signal received power may be determined and configured by the following formula, the specific formula is as follows:

[0164]

[0165] Among them, x p represents the RSRP mean of MR, that is, the average value of the reference signal received power (RSRP) of the initially selected users, x i represents the RSRP value reported in each MR, that is, the RSRP value reported by the preliminarily selected user in the i-th measurement report (MR), and n represents the total number of MR sampling points.

[0166] The meaning and purpose of the algorithm are:

[0167] Identify resident users: Through the resident algorithm introduced earlier, we have screened out a group of resident users.

[0168] Calculate the RSRP average: For these resident users, calculate their RSRP average in the elevator cell.

[0169] Handling special cases: If a resident user meets the definition of a resident user but has no Internet access log in the elevator cell, but only has Internet access log in the outdoor cell, then the RSRP average of this user is considered to be -128.

[0170] The purpose of setting the average RSRP value of users without Internet access logs to -128 is:

[0171] Meaning of -128: In wireless communications, -128dBm usually means a very weak signal or no signal.

[0172] Handling special cases: If a resident user has no Internet access log in the elevator, but has Internet access log near the elevator, it can be inferred that the signal in the elevator may be very weak or even without coverage. Setting the RSRP mean to -128 can mark this special case for subsequent analysis.

[0173] Avoid misjudgment: This process can prevent some areas with poor signal quality from being mistaken for areas with good signal coverage.

[0174] The advantages of the algorithm are:

[0175] Single effective: By calculating the average value, the signal quality of the user in the elevator can be quickly evaluated.

[0176] Easy to implement: The algorithm is simple to implement and requires little computation.

[0177] Ability to identify special cases: Users who are regular users but have poor signal quality in the elevator can be identified.

[0178] In addition, we can also consider introducing the time dimension into the analysis to analyze the changes in RSRP of users in different time periods.

[0179] Consider other signal quality indicators: In addition to RSRP, other signal quality indicators can also be considered, such as SINR, CQI, etc.

[0180] Combine user feedback: The algorithm results can be corrected based on user feedback.

[0181] By calculating the RSRP average of resident users and performing special processing on users without Internet access logs, the signal coverage in the elevator can be more comprehensively evaluated. This algorithm provides important data support for the subsequent detection process.

[0182] In an optional embodiment of the present invention, the step of generating a fault detection result for the target elevator based on the signal distribution information includes:

[0183] Determine the coverage value of the specific signal in the target elevator and the probability of occurrence of the coverage value according to the signal distribution information;

[0184] Calculating an expected value for the specific signal using the coverage value and the occurrence probability;

[0185] A fault detection result for the target elevator is generated according to the expected value.

[0186] In practical applications, in order to better comprehensively evaluate the overall signal situation of elevator resident users, the embodiments of the present invention can introduce a covered discrete probability function to describe the signal distribution of resident users in the elevator.

[0187] In a specific implementation, the coverage value of a specific signal in a target elevator and the probability of occurrence of the coverage value can be obtained through the signal distribution information.

[0188] Exemplarily, the expected value can be calculated by the following formula, and the specific formula definition is as follows:

[0189] P i =P(X i )

[0190] Among them, X i Represents the coverage value, P i Represents the coverage value is X i probability.

[0191] The expected calculation formula is as follows:

[0192]

[0193] The above formula represents the expectation of a random variable.

[0194] E: represents the expectation of a random variable, which is the weighted average of all possible values ​​of the random variable.

[0195] X i Represents the coverage value that has.

[0196] P i Represents the coverage value is X i probability.

[0197] Σ(j=1to m): means summing all possible values, and m means the number of all possible values.

[0198] The above formula calculates the average value of a random variable, but considering that the probability of each value occurring is different, a weighted average is taken for each value.

[0199] In the elevator signal coverage scenario, this formula is used to describe the distribution of signal coverage of resident users in the elevator.

[0200] Xi: represents the signal coverage value (such as RSRP value) of a certain location in the elevator.

[0201] Pj: represents the probability of a resident user appearing at this location.

[0202] E: represents the average signal coverage value of permanent users in the elevator.

[0203] By calculating this expected value, a comprehensive indicator can be obtained to evaluate the overall signal quality of resident users in the elevator. For example, if the current expectation is less than -105, the elevator coverage has an invisible coverage failure.

[0204] In an optional embodiment of the present invention, the step of generating a fault detection result for the target elevator by using the expected value includes:

[0205] When the expected value is greater than a preset threshold, the current expected value of the resident user and the expected value of the resident user's previous situation are determined;

[0206] Calculate the expected relative change rate by using the current expected value of the resident user and the previous expected value of the resident user;

[0207] When the expected relative change rate is greater than a preset change rate threshold, a fault detection result for the target elevator is generated, and the fault detection result is used to determine a threshold for an invisible fault in the signal coverage of the target elevator.

[0208] If the current signal strength is expected to be greater than or equal to -105, the expected rate of change of the probability function is used to determine the signal change of the resident user over a period of time. The definition is as follows:

[0209]

[0210] F is the expected relative rate of change, E 2 is the current expected value of the resident user, E 1 The expected value of the previous situation for the resident user.

[0211] The past expected values ​​may be stored in a specific hardware device, and the embodiment of the present invention may read the expected values ​​of the previous situations of the resident user from the hardware device when necessary.

[0212] If F is less than 0, it means that the elevator signal has not deteriorated, and if it is greater than 0, it means that the elevator signal has deteriorated.

[0213] Exemplarily, the preset change rate threshold may be set to 10%; if F is greater than or equal to 10%, it may be determined that the signal coverage of the target elevator has a threshold for an invisible fault.

[0225] The electronic device 400 includes but is not limited to: a radio frequency unit 401, a network module 402, an audio output unit 403, an input unit 404, a sensor 405, a display unit 406, a user input unit 407, an interface unit 408, a memory 409, a processor 410, and a power supply 411. Those skilled in the art will appreciate that Figure 4 The electronic device structure shown in the figure does not constitute a limitation on the electronic device, and the electronic device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently. In the embodiments of the present invention, the electronic device includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device, and a pedometer.

[0226] It should be understood that in the embodiment of the present invention, the radio frequency unit 401 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving downlink data from the base station, it is sent to the processor 410 for processing; in addition, uplink data is sent to the base station. Generally, the radio frequency unit 401 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 401 can also communicate with the network and other devices through a wireless communication system.

[0227] The electronic device provides users with wireless broadband Internet access through the network module 402, such as helping users to send and receive emails, browse web pages, and access streaming media.

[0228] The audio output unit 403 can convert the audio data received by the RF unit 401 or the network module 402 or stored in the memory 409 into an audio signal and output it as sound. Moreover, the audio output unit 403 can also provide audio output related to a specific function performed by the electronic device 400 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 403 includes a speaker, a buzzer, a receiver, etc.

[0229] The input unit 404 is used to receive audio or video signals. The input unit 404 may include a graphics processor (GPU) 4041 and a microphone 4042, and the graphics processor 4041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 406. The image frame processed by the graphics processor 4041 can be stored in the memory 409 (or other storage medium) or sent via the radio frequency unit 401 or the network module 402. The microphone 4042 can receive sound and can process such sound into audio data. The processed audio data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 401 in the case of a telephone call mode.

[0230] The electronic device 400 also includes at least one sensor 405, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 4061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 4061 and / or the backlight when the electronic device 400 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary, which can be used to identify the posture of the electronic device (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; the sensor 405 can also include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which will not be repeated here.

Specifically, the user input unit 407 includes a touch panel 4071 and other input devices 4072. The touch panel 4071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 4071 or near the touch panel 4071 using any suitable object or accessory such as a finger, stylus, etc.). The touch panel 4071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the contact point coordinates, and then sends it to the processor 410, receives the command sent by the processor 410 and executes it. In addition, the touch panel 4071 can be implemented using various types such as resistive, capacitive, infrared and surface acoustic waves. In addition to the touch panel 4071, the user input unit 407 may also include other input devices 4072. Specifically, other input devices 4072 may include but are not limited to a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, and a joystick, which are not described in detail here.

[0233] Furthermore, the touch panel 4071 may be overlaid on the display panel 4061. When the touch panel 4071 detects a touch operation on or near it, it is transmitted to the processor 410 to determine the type of the touch event. Then, the processor 410 provides a corresponding visual output on the display panel 4061 according to the type of the touch event. Figure 4 In the figure, the touch panel 4071 and the display panel 4061 are two independent components to realize the input and output functions of the electronic device. However, in some embodiments, the touch panel 4071 and the display panel 4061 can be integrated to realize the input and output functions of the electronic device, which is not limited here.

[0236] The processor 410 is the control center of the electronic device. It uses various interfaces and lines to connect various parts of the entire electronic device. It executes various functions of the electronic device and processes data by running or executing software programs and / or modules stored in the memory 409, and calling data stored in the memory 409, so as to monitor the electronic device as a whole. The processor 410 may include one or more processing units; preferably, the processor 410 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 410.

[0237] The electronic device 400 may also include a power supply 411 (such as a battery) for supplying power to each component. Preferably, the power supply 411 may be logically connected to the processor 410 through a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0238] In addition, the electronic device 400 includes some functional modules not shown, which will not be described in detail here.

[0239] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
