Description

A navigation prompting method, apparatus, electronic device, and storage medium

Technical Field

This invention relates to the field of computer technology, and in particular to a navigation prompting method, apparatus, electronic device, and storage medium.

Background Technology

Currently, using electronic maps for navigation while driving is very common. Electronic maps can provide guidance on lane markings at intersections during navigation. In related technologies, when there is a discrepancy between the number of lanes in the middle of the road (the number of lanes in the normal driving lanes before entering the intersection) shown in Figure 1 and the number of lanes at the intersection (the number of lanes before the stop line at the intersection, usually separated by solid lines and with turn-guiding arrows), the guidance on the middle lanes is based solely on the lane markings at the intersection. Taking Figure 1 as an example, assuming a navigation prompt is given at location X in Figure 1, since the lane markings at this intersection indicate that the two middle lanes are straight lanes, the navigation prompt would be "take the two middle lanes." However, there is only one middle lane at location X in Figure 1. It is evident that the navigation prompts provided in these technologies are not accurate enough, making it impossible for users to determine from the prompts whether they are currently driving in the correct lane or whether a lane change is necessary.

Detailed Implementation

The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

It is understood that in the specific embodiments of the present invention, data such as user information are involved. When the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

Please refer to Figure 2a, which shows a schematic diagram of an implementation environment provided by an embodiment of the present invention. The implementation environment may include a terminal 210 and a server 220. The terminal 210 and the server 220 can be directly or indirectly connected through wired or wireless communication. The present invention does not impose any limitations on this.

The terminal 210 may include, but is not limited to, mobile phones, computers, smart voice interaction devices, smart home appliances, in-vehicle terminals, etc. The terminal 210 runs client software with navigation functions, such as an application (App). This application can be a standalone application or a subroutine within an application.

Server 220 can be a server that provides background services for applications in terminal 210. Specifically, the service provided by server 220 can be a navigation prompt service based on map data. For example, in the initial navigation route planning stage, a target navigation route is generated based on map data, and lane prompt mapping information corresponding to each target prompt location information on the target navigation route is generated based on the target navigation route. The target prompt location information is the location of the navigation prompt information in the corresponding lane prompt mapping information that needs to be output.

In one specific embodiment, after generating lane guidance mapping information corresponding to each target location, server 220 can send it to terminal 210, which initiated the navigation route planning, so that terminal 210 can provide timely navigation prompts based on the lane guidance mapping information corresponding to each target location during the navigation based on the target navigation route. In another specific embodiment, after generating lane guidance mapping information corresponding to each target location, server 220 may not send it to terminal 210, which initiated the navigation route planning, but instead store it locally. During the navigation based on the target navigation route, server 220 can send corresponding navigation prompts to terminal 210 based on its real-time driving location and the lane guidance mapping information corresponding to each target location.

Server 220 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

In one exemplary implementation, both terminal 210 and server 220 can be node devices in a blockchain system, capable of sharing acquired and generated information with other node devices in the blockchain system, thus enabling information sharing among multiple node devices. Multiple node devices in the blockchain system can be configured with the same blockchain, which consists of multiple blocks, and adjacent blocks are related, ensuring that any data tampering in any block can be detected by the next block, thereby preventing data tampering in the blockchain and guaranteeing the security and reliability of the data in the blockchain.

The navigation prompting method provided in this invention can be applied to various scenarios such as cloud technology, intelligent transportation, and the Internet of Vehicles.

Cloud technology, including cloud computing, is a computing model that distributes computing tasks across a resource pool comprised of numerous computers, enabling various application systems to access computing power, storage space, and information services as needed. The network providing these resources is called the "cloud." From the user's perspective, resources in the "cloud" appear infinitely scalable, readily available, on-demand, and expandable, with payment based on usage. As a provider of fundamental cloud computing capabilities, a cloud resource pool (referred to as a cloud platform, generally called an IaaS (Infrastructure as a Service) platform) is established. Various types of virtual resources are deployed within this pool for external customers to choose from. The cloud resource pool mainly includes: computing devices (virtualized machines containing operating systems), storage devices, and network devices. Logically, a PaaS (Platform as a Service) layer can be deployed on top of the IaaS layer, and a SaaS (Software as a Service) layer can be deployed on top of the PaaS layer. Alternatively, SaaS can be directly deployed on top of IaaS. PaaS is a platform for running software, such as databases and web containers. SaaS refers to various types of business software, such as web portals and bulk SMS senders. Generally, SaaS and PaaS are upper layers compared to IaaS.

Intelligent Transportation Systems (ITS) are comprehensive transportation systems that effectively integrate advanced technologies (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations research, artificial intelligence, etc.) into transportation, service control, and vehicle manufacturing. They strengthen the connection between vehicles, roads, and users, thereby forming a comprehensive transportation system that ensures safety, improves efficiency, improves the environment, and saves energy.

The concept of the Internet of Vehicles (IoV) originates from the Internet of Things (IoT), specifically the Vehicle Internet of Things. It uses moving vehicles as information sensing objects and leverages next-generation information and communication technologies to achieve network connectivity between vehicles and X (i.e., vehicles, people, roads, and service platforms). This enhances the overall intelligent driving level of vehicles, providing users with a safe, comfortable, intelligent, and efficient driving experience and transportation services, while simultaneously improving traffic efficiency and the overall intelligence of social transportation services. Vehicle-to-vehicle communication refers to the exchange and sharing of information between vehicles, including vehicle location, speed, and other vehicle status information, which can be used to assess road traffic conditions. Vehicle-to-infrastructure communication refers to the exchange of information between vehicles and roads through fixed roadside communication facilities, used to monitor road conditions and guide vehicles to choose the optimal driving path.

The navigation prompting method provided by the embodiments of the present invention will be described in detail below with reference to the application environment shown in Figure 2a. It should be noted that the navigation prompting method of the embodiments of the present invention can be applied to a navigation prompting device, which can be configured in an electronic device, such as a terminal or a server.

Please refer to Figure 2b, which shows a flowchart of a navigation prompting method provided by an embodiment of the present invention. It should be noted that this specification provides the operational steps of the method as described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only execution order. In actual system or product execution, the method can be executed sequentially according to the embodiments or figures, or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown in Figure 2b, the method may include:

S201, if the current driving position meets the navigation prompt conditions, determine the current driving lane corresponding to the current driving position and the target prompt position information corresponding to the current driving position.

The current driving position can be obtained using GPS (Global Positioning System) location information. The current driving lane corresponding to the current driving position refers to the lane in which the vehicle is currently traveling, determined based on the current driving position. In practical applications, image recognition, positioning chips, sensors, and other methods can be used to determine the current driving lane.

The driving lane refers to the lane on the normal driving lane before entering the intersection area. The intersection area refers to the area belonging to a certain intersection as indicated by the standard road data in the standard road database. Figure 3 shows a schematic diagram of lanes including the intersection. The intersection lane refers to the lane before the vehicle stop line at the intersection, which is generally divided by a solid line and has guide lane lines (i.e., guide arrows in Figure 3).

Target location information refers to the location where navigation prompts are required. In this embodiment of the invention, after generating the target navigation path, the target location information corresponding to each intersection along the target navigation path can be determined. Therefore, during navigation based on the target navigation path, if the current driving position matches a target location information, it indicates that the navigation prompt condition is met, triggering a navigation prompt command. The terminal then responds to this command by outputting navigation prompts. In practical applications, to trigger navigation prompt commands and output navigation prompts, the target location information is generally a range of locations. When the current driving position falls within the range indicated by a target location information, it indicates that the current driving position has matched that target location information.

Based on this, in an exemplary embodiment, the method may further include:

Get the current driving location;

Search among the multiple target prompt location information to find the target prompt location information that contains the current driving location;

If found, the current driving location is determined to meet the navigation prompt conditions.

The above embodiments can improve the real-time performance of navigation prompts by directly searching for the target prompt location information that matches the current driving position among multiple target prompt location information.

S203, obtain the lane prompt mapping information corresponding to the target prompt location information.

The lane prompt mapping information represents the mapping relationship between the driving lane corresponding to the target prompt location information and the navigation prompt information. The navigation prompt information is generated based on the correspondence between the driving lane and the intersection lane. The intersection lane refers to the lane at the intersection corresponding to the target prompt location information.

In this embodiment of the invention, the lane guidance mapping information corresponding to each target prompt location information is generated during the navigation path planning stage before navigation. Therefore, when actually navigating based on the target navigation path, the lane guidance mapping information corresponding to that target prompt location information can be obtained based on the target prompt location information hit by the current driving position. The lane guidance mapping information corresponding to each target prompt location information will be described in detail in the subsequent sections of this embodiment.

S205, determine the target navigation prompt information corresponding to the current driving lane in the lane prompt mapping information.

Specifically, the target mapping relationship matching the current lane can be determined from the lane mapping information corresponding to the hit target location information, and then the target navigation prompt information in the target mapping relationship can be obtained. The target navigation prompt information is generated based on the correspondence between the lane corresponding to the hit target location information and the intersection lane of the corresponding intersection.

S207, Output navigation prompts based on the target navigation prompt information.

For example, navigation prompts can be output in voice form based on the target navigation information, such as "Please continue in the current lane", "Please change one lane to the right", "Please change two lanes to the left".

As can be seen from the above technical solutions of the embodiments of the present invention, in the embodiments of the present invention, since the lane prompt mapping information represents the mapping relationship between the driving lane corresponding to the target prompt location information and the navigation prompt information, the target navigation prompt information corresponding to the current driving lane can be determined from the lane prompt mapping information. Since the navigation prompt information corresponding to the driving lane is generated according to the correspondence between the driving lane and the intersection lane, the navigation prompt information can provide more accurate guidance when the number of driving lanes is inconsistent with the number of intersection lanes. This allows the user to determine more accurately in advance whether they are driving in the correct lane and whether they need to change lanes, thereby providing a better assisted driving experience.

In one exemplary embodiment, the navigation prompting method of this invention may further include a process for generating lane prompting mapping information corresponding to the target prompting location information, as shown in FIG4. Generating lane prompting mapping information corresponding to the target prompting location information may include:

S401, Generate the target navigation path based on the starting position and the destination position.

The starting and target locations can be information entered into an electronic map.

S403, based on the turning positions in the target navigation path, divide the target navigation path into at least one navigation segment.

Each navigation segment, after being divided, includes a turning position, and this turning position is located at the end of the navigation segment.

S405, based on the guide lane line information of the intersection in each navigation segment, determine the target prompt location information corresponding to the intersection and the driving lane information corresponding to the target prompt location information.

In practical applications, each navigation segment may contain one or more intersections, and each intersection may have one or more guide lane lines. The guiding directions of each guide lane line may be the same or different. Based on the guide lane line information corresponding to each intersection in each navigation segment, the target location information corresponding to each intersection and the driving lane information corresponding to that target location information can be determined.

In one exemplary embodiment, step S405, when implemented as shown in FIG5, may include the following steps:

S501, based on the guide lane line information of the intersection in the navigation segment, determine the position in the navigation segment that is a preset distance away from the guide lane line of the intersection, and obtain the target prompt position information corresponding to the intersection.

For example, the preset distance can be a fixed distance set in advance, such as 200 meters. To improve the real-time performance of navigation prompts and enhance driving safety, the preset distance can also be a distance selected from distance attribute mapping information that matches the lane attributes of the intersection. The distance attribute mapping information represents the correspondence between the lane attributes of the intersection and the preset distance; that is, different lane attributes can correspond to different preset distances, thus ensuring that the preset distances for each intersection match the road attributes of that intersection. Intersection road attributes can include the width of the intersection road and the intersection type (such as a highway intersection, an urban road intersection, etc.).

The distance between the guide lane line at the intersection can be the distance extended from the end of the guide lane line in the opposite direction of the driving direction. This allows the location in the navigation segment to be found at a preset distance from the guide lane line at the intersection. Based on this location, the target prompt location information corresponding to the intersection can be obtained. The specific target prompt location information can be a location range determined based on the above location. The size of this range can be determined based on practical experience.

S503, determine the lane change point in the navigation segment, where the lane change point refers to the location in the navigation segment where the number of lanes changes.

As shown in Figure 3, the location where the number of lanes changes from 3 to 4 is a lane change point. It can be understood that each navigation segment can have multiple lane change points. Each lane change point corresponds to lane information before the lane number change (3 lanes in the middle of the lane as shown in Figure 3) and lane information after the lane number change (4 lanes in the middle of the lane as shown in Figure 3).

S505, determine a first distance between the lane change point and the turning position corresponding to the navigation segment, and a second distance between the guide lane line of the intersection and the turning position.

The second distance between the guide lane line at the intersection and the turning position can refer to the distance from the end of the guide lane line extending in a straight line in the direction of travel to the turning position corresponding to the navigation segment.

S507, determine the target lane change point based on the first distance, the second distance and the preset distance.

The target lane change point is the lane change point with the smallest difference, and the difference is the difference between the sum of the second distance and the preset distance and the first distance.

In specific implementation, the preset distance can be denoted as voice_dis, the second distance between the guide lane line at the intersection and the turning position can be denoted as dis_to_event, and the first distance between the lane change point and the turning position can be denoted as s. Then, based on (voice_dis + dis_to_event), the first lane change point where s is less than or equal to (voice_dis + dis_to_event) can be found as the target lane change point. That is, the s corresponding to the target lane change point is less than (voice_dis + dis_to_event), and the difference between (voice_dis + dis_to_event) and s is the smallest.

S509, Based on the lane before the lane number change corresponding to the target lane change point, generate the lane information corresponding to the target prompt location information.

In the above embodiments, the lane information corresponding to each target prompt location in the navigation segment can be quickly and accurately determined by the distance between the lane change point and the turning position, the distance between the guide lane line at the intersection and the turning position, and the location where navigation prompts need to be output for the intersection.

S407, Based on the driving lane information corresponding to the target prompt location information and the guide lane line information of the intersection, determine the correspondence between the driving lane corresponding to the target prompt location information and the intersection lane.

Each target location can correspond to multiple lanes in the road, and each lane in the road can correspond to one or more intersection lanes. When a lane in the road is associated with an intersection lane, it means that the lane in the road and the intersection lane are connected. Lanes in the road that are not associated with an intersection lane are not connected. When the intersection lane in the associated relationship is a passable lane, vehicles can only enter the intersection lane by passing through the lane in the associated relationship. Vehicles in other lanes in the road can only enter the intersection lane by changing lanes to the lane in the associated relationship.

In an exemplary embodiment, step S407, when determining the correspondence between the lane in the middle of the road corresponding to the target prompt location information and the lane markings at the intersection based on the lane information in the middle of the road corresponding to the target prompt location information and the guide lane markings at the intersection, may include:

Based on the guide lane line information of the intersection, the intersection lanes corresponding to the intersection are determined; the intersection lanes include straight-ahead intersection lanes and additional intersection lanes;

Based on the lane information corresponding to the target prompt location information, determine the associated lanes in the middle of the road that are related to the additional intersection lanes, and take the lanes in the middle of the road other than the associated lanes as the remaining lanes in the middle of the road.

Establish the correspondence between the associated lanes in the middle of the road and the lanes at the first intersection, as well as the correspondence between the remaining lanes in the middle of the road and the lanes at the second intersection;

The first intersection lane includes the additional intersection lane corresponding to the associated traffic lane and the straight-through intersection lane adjacent to the additional intersection lane. The second intersection lane is the straight-through intersection lane other than the straight-through intersection lane adjacent to the additional intersection lane.

Additional intersection lanes are intersection lanes extended to improve intersection capacity. They can be divided into left-side and right-side additional lanes, used to facilitate different turns at the intersection. It is understood that the additional intersection lanes in this embodiment may include both left-side and right-side additional lanes, or even just either left-side or right-side additional lanes. Straight-through intersection lanes are lanes other than the additional intersection lanes, used to allow straight-through traffic through the intersection. As shown in the lane diagram in Figure 6, T1 and T5 are additional intersection lanes, and T2 to T4 are straight-through intersection lanes. Associated driving lanes related to additional intersection lanes refer to driving lanes located on the same side as the additional intersection lanes, near the road edge. As shown in Figure 6, the associated driving lane for T1 is C1, the associated driving lane for T5 is C3, and C2 is the remaining driving lane.

The following uses Figure 6 as an example to illustrate the establishment of the correspondence between the driving lanes and intersection lanes. As shown in Figure 6, the intersection lanes are: the first additional intersection lane is T1, the second additional intersection lane is T5, and the straight-ahead intersection lanes are T2 to T4; the driving lanes corresponding to the target location information are: the first associated driving lane is C1, the second associated driving lane is C3, and the remaining driving lane is C2. The straight-ahead intersection lane adjacent to the first additional intersection lane T1 is T2, the straight-ahead intersection lane adjacent to the second additional intersection lane is T4, and the second intersection lane is T3. Then, establish the correspondence between C1 and T1, T2, C3 and T4, T5, and C2 and T3. After the above correspondence is established, it means that C1 is connected to T1, T2, C3 is connected to T4, T5, and C2 is connected to T3. Thus, the correspondence between the driving lane and the intersection lane corresponding to the target prompt location information can be represented as {C1-->(T1,T2); C2-->T3; C3-->(T4,T5)}.

In the above embodiments, establishing an accurate connection relationship between each lane in the middle of the line corresponding to the target prompt location information and each intersection lane is beneficial for subsequently generating accurate navigation prompt information for each lane in the middle of the line based on this accurate connection relationship.

S409, Based on the correspondence between the driving lane and the intersection lane corresponding to the target prompt location information, generate lane prompt mapping information corresponding to the target prompt location information.

Among them, the lane indication mapping information is the mapping relationship between the driving lane and the navigation prompt information. This navigation prompt information is used to indicate whether a lane change is needed, and if a lane change is needed, to further indicate which direction to change lanes in and how many lanes to change, etc.

In one specific implementation, step S409, when generating lane prompt mapping information corresponding to the target prompt location information based on the correspondence between the driving lane and the intersection lane corresponding to the target prompt location information, may include:

Determine the intersection corresponding to the target location information and the corresponding driving direction information in the target planned path;

Based on the guide lane information of the intersection, determine the passage lane of the intersection that matches the driving direction information;

Based on the correspondence between the driving lane and the intersection lane corresponding to the target prompt location information, determine the driving lane corresponding to the passing intersection lane;

Based on the relative position of the through lane and the through intersection lane, a first navigation prompt information corresponding to the through lane is generated, and based on the relative position of each non-through lane and the through lane, a second navigation prompt information corresponding to each non-through lane is generated; wherein, the non-through lane is a lane other than the through lane among the through lanes corresponding to the target prompt location information.

Taking Figure 6 as an example, (1) Assuming that the direction of travel corresponding to the intersection of the target prompt location information is to turn left at the intersection, then according to the guide lane line information of the intersection in Figure 6, it can be determined that the passing intersection lanes that match the left turn at the intersection are T1 and T2. According to the correspondence between the passing lane and the intersection lane corresponding to the aforementioned target prompt location information {C1-->(T1,T2); C2-->T3; C3-->(T4,T5)}, it can be seen that C1 is the passing passing lane, and C2 and C3 are both non-passing passing lanes. Then, the first navigation prompt information is generated for C1, such as "Please continue driving along the current lane" or "Please turn left along the current lane", the second navigation prompt information is generated for C2, such as "Please change lanes to the left" or "Please change one lane to the left", and the second navigation prompt information is generated for C3, such as "Please change two lanes to the left".

(2) Assuming that the intersection corresponding to the target prompt location information corresponds to a right turn at the intersection in the target planning path, then according to the guide lane line information of the intersection in Figure 6, it can be determined that the passing intersection lanes that match the right turn at the intersection are T4 and T5. According to the correspondence between the passing lanes and intersection lanes corresponding to the aforementioned target prompt location information {C1-->(T1,T2); C2-->T3; C3-->(T4,T5)}, it can be seen that C3 is a passing passing lane, while C1 and C2 are both non-passing passing lanes. Therefore, a first navigation prompt information is generated for C3, such as "Please continue driving in the current lane" or "Please turn right in the current lane". A second navigation prompt information is generated for C2, such as "Please change lanes to the right" or "Please change one lane to the right". A second navigation prompt information is generated for C1, such as "Please change two lanes to the right".

(3) Assuming that the intersection corresponding to the target prompt location information corresponds to the straight driving direction information in the target planning path, then according to the guide lane line information of the intersection in Figure 6, it can be determined that the passing lanes at the intersection that match the straight driving direction at the intersection are T2 to T5. According to the correspondence between the driving lanes and intersection lanes corresponding to the target prompt location information {C1-->(T1,T2); C2-->T3; C3-->(T4,T5)}, it can be seen that C1 to C3 are all driving lanes. Therefore, the first navigation prompt information is generated for C1 to C3, such as "Please continue driving along the current lane" or "Please go straight along the current lane".

In the above embodiments, based on the driving direction information of the intersection corresponding to the target prompt location information in the target planned path and the correspondence between the lane in the middle of the road corresponding to the target prompt location information and the lane at the intersection, navigation prompt information corresponding to each lane in the middle of the road can be accurately generated, thereby improving the accuracy of navigation prompt information.

This invention provides an electronic device, which includes a processor and a memory. The memory stores at least one instruction or at least one program segment. The at least one instruction or the at least one program segment is loaded and executed by the processor to implement the navigation prompting method provided in the above-described method embodiments.

Memory can be used to store software programs and modules. The processor executes various functional applications and data processing by running the software programs and modules stored in the memory. Memory can primarily include a program storage area and a data storage area. The program storage area can store the operating system, application programs required for the functions, etc.; the data storage area can store data created based on the use of the device, etc. Furthermore, memory can include high-speed random access memory, and can also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, memory can also include a memory controller to provide the processor with access to the memory.

The method embodiments provided in this invention can be executed in a computer terminal, server, or similar computing device. Taking running on a terminal as an example, Figure 8 is a hardware structure block diagram of a terminal running a navigation prompting method according to an embodiment of this invention. Specifically:

The terminal may include an RF (Radio Frequency) circuit 810, a memory 820 including one or more computer-readable storage media, an input unit 830, a display unit 840, a sensor 850, an audio circuit 860, a WiFi (Wireless Fidelity) module 870, a processor 880 including one or more processing cores, and a power supply 890, etc. Those skilled in the art will understand that the terminal structure shown in FIG8 does not constitute a limitation on the terminal, and may include more or fewer components than shown, or combine certain components, or have different component arrangements. Wherein:

The RF circuit 810 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and hands it over to one or more processors 880 for processing; additionally, it transmits uplink data to the base station. Typically, the RF circuit 810 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, an LNA (Low Noise Amplifier), a duplexer, etc. Furthermore, the RF circuit 810 can also communicate wirelessly with networks and other terminals. The wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), email, SMS (Short Messaging Service), etc.

The memory 820 can be used to store software programs and modules. The processor 880 executes various functional applications and data processing by running the software programs and modules stored in the memory 820. The memory 820 may mainly include a program storage area and a data storage area. The program storage area may store the operating system, application programs required for the functions, etc.; the data storage area may store data created according to the use of the terminal, etc. In addition, the memory 820 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, the memory 820 may also include a memory controller to provide access to the memory 820 for the processor 880 and the input unit 830.

The input unit 830 can be used to receive input digital or character information, and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control. Specifically, the input unit 830 may include a touch-sensitive surface 831 and other input devices 832. The touch-sensitive surface 831, also known as a touch display screen or touchpad, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch-sensitive surface 831), and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface 831 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 880, and can receive and execute commands sent by the processor 880. In addition, the touch-sensitive surface 831 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch-sensitive surface 831, the input unit 830 may also include other input devices 832. Specifically, other input devices 832 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

The display unit 840 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the terminal. These graphical user interfaces can be composed of graphics, text, icons, video, and any combination thereof. The display unit 840 may include a display panel 841, which may optionally be configured as an LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), or similar form. Further, a touch-sensitive surface 831 may cover the display panel 841. When the touch-sensitive surface 831 detects a touch operation on or near it, it transmits the information to the processor 880 to determine the type of touch event. Subsequently, the processor 880 provides corresponding visual output on the display panel 841 according to the type of touch event. The touch-sensitive surface 831 and the display panel 841 can be two independent components to implement input and output functions. However, in some embodiments, the touch-sensitive surface 831 and the display panel 841 can be integrated to achieve input and output functions.

The terminal may also include at least one sensor 850, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel 841 according to the ambient light level, and the proximity sensor can turn off the display panel 841 and/or backlight when the terminal is moved to the ear. As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that identify the terminal's posture (such as landscape/portrait switching, related games, magnetometer posture calibration), vibration recognition-related functions (such as pedometer, tapping), etc. Other sensors that may be configured on the terminal, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

Audio circuitry 860, speaker 861, and microphone 862 provide an audio interface between the user and the terminal. Audio circuitry 860 converts received audio data into electrical signals, which are then transmitted to speaker 861, where they are converted into sound signals for output. Conversely, microphone 862 converts collected sound signals into electrical signals, which are received by audio circuitry 860, converted back into audio data, and then processed by processor 880 before being transmitted via RF circuitry 810 to, for example, another terminal, or output to memory 820 for further processing. Audio circuitry 860 may also include an earphone jack to facilitate communication between a peripheral headset and the terminal.

WiFi is a short-range wireless transmission technology. The terminal, through the WiFi module 870, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 8 shows the WiFi module 870, it is understood that it is not an essential component of the terminal and can be omitted as needed without changing the essence of the invention.

The processor 880 is the control center of the terminal, connecting various parts of the terminal via various interfaces and lines. It executes software programs and/or modules stored in the memory 820, and calls data stored in the memory 820 to perform various functions and process data, thereby providing overall monitoring of the terminal. Optionally, the processor 880 may include one or more processing cores; preferably, the processor 880 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 880.

The terminal also includes a power supply 890 (such as a battery) to power various components. Preferably, the power supply can be logically connected to the processor 880 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply 890 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.
