Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) mobile terminal technology, and in particular to an automatic control system, method, terminal, and medium for the communication processor function of an IoT terminal. Background Technology

[0002] With the rapid development of IoT technology, mobile terminals have been widely used across various industries. The vast majority of these IoT terminals are unattended devices, and their application processors handle relatively simple business logic, primarily focusing on specific data collection or transmission tasks. Meanwhile, chip manufacturers providing communication capabilities for these terminals typically integrate rich network functions into their communication processors or modems. However, due to the relatively fixed business models of IoT terminals, these integrated communication functions are often underutilized, resulting in idle hardware resources and wasted potential performance.

[0003] Taking practical application scenarios as an example, terminals supporting multi-mode networks can flexibly switch between single-mode and multi-mode operating modes based on network coverage quality. However, without a dynamic adjustment mechanism, terminals typically remain in a fixed mode. Similarly, some IoT devices requiring location information may remain stationary for extended periods after deployment; continuously enabling location services would lead to unnecessary energy consumption. Therefore, for unmanned IoT terminals, there is an urgent need for a hardware and software control mechanism built into the application processor. This mechanism should automatically determine the activation and deactivation of communication functions without manual intervention, based on the terminal's actual operating scenario and business status. This would improve function utilization while ensuring that functions are accurately invoked at the appropriate time.

[0004] In existing technological solutions, while mobile terminals like smartphones possess rich modem functions, they primarily rely on human-computer interaction interfaces for manual user control. For example, users can invoke location services by opening or closing specific applications. Due to the complexity of usage scenarios and the dominance of human operation, it is difficult to form a fully automated function scheduling mechanism. For IoT mobile terminals, the industry generally adopts a pre-configuration method to set the communication side's operating parameters before powering on. Although this method can initialize the functional state to a certain extent, it cannot perceive changes in the actual application scenario after powering on. When the terminal's location, network environment, or service load dynamically changes, the pre-configured static strategy is unable to adaptively adjust the communication side functions, resulting in a significant disconnect between functional usage and real-world scenario requirements. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an automatic control system, method, terminal and medium for the communication processor function of an Internet of Things terminal, which solves the technical problems of existing technologies that rely on human-computer interaction and are difficult to achieve automated control, or can only run based on static pre-configuration before power-on and cannot adapt to the dynamic changes of application scenarios, resulting in the communication processor function not being able to be automatically and accurately enabled or disabled according to scenario requirements in actual use.

[0006] To achieve the above and other related objectives, this invention provides an automatic control system for the communication processor function of an IoT terminal. The system utilizes an IoT mobile terminal and includes: an application processor and a communication processor; the application processor is used to acquire one or more of terminal configuration information, sensor information, or service status information, identify the current application scenario based on built-in automatic control logic, determine the activation timing of the corresponding function of the communication processor, and send corresponding function control commands to the communication processor via AT commands; the communication processor is used to receive and execute the function control commands, switch to the corresponding function state, and initiate a registration notification to the network; the functions of the communication processor include: single-mode / multi-mode switching, positioning, and power-saving functions.

[0007] In one embodiment of the present invention, after the IoT mobile terminal is powered on, the application processor reads the terminal configuration information and receives the 5G network cell camping status reported by the communication processor via AT commands. It determines that the IoT mobile terminal currently requires a stable network camping environment, and sends a 5G Only mode configuration instruction to the communication processor via AT commands to control the communication processor to enable the 5G Only single-mode function and initiate initial registration with the network on the 5G network cell. The terminal configuration information includes the factory configuration parameters of the wireless fixed-line product form.

[0008] In one embodiment of the present invention, the application processor also monitors the signal quality of the 5G network in real time. When the signal quality of the 5G network is detected to drop below a preset threshold, the application processor sends a multi-mode recovery configuration instruction to the communication processor via AT command to disable the 5G only single-mode function.

[0009] In one embodiment of the present invention, when the application processor receives information from a sensor that the IoT mobile terminal has moved from a stationary state, it sends a positioning function instruction to the communication processor via an AT command to control the communication processor to enable the positioning function, initiate an update registration notification to the network to enable the positioning function, and operate the positioning-related services normally. When the application processor receives information from a sensor that the IoT mobile terminal has returned from a moving state to a stationary state, it sends a positioning function deactivation instruction to the communication processor via an AT command to control the communication processor to deactivate the positioning function, and initiate an update registration notification to the network to deactivate the positioning function.

[0010] In one embodiment of the present invention, when the application processor receives information from the sensor that the Internet of Things mobile terminal has returned from a mobile state to a stationary state for a preset reasonable time, it sends an AT command to the communication processor to disable the positioning function.

[0011] In one embodiment of the present invention, when the application processor receives information that the corresponding IoT mobile terminal has returned to the service idle state after the service operation has ended, it sends an AT command to the communication processor to enable the power saving function, controls the communication processor to set the power saving function to be enabled, and initiates an update registration notification to the network to enable the power saving function; when the application processor receives information that the corresponding IoT mobile terminal has initiated the operation of a new service in the service idle state, it sends an AT command to the communication processor to disable the power saving function, controls the communication processor to set the power saving function to be disabled, and initiates an update registration notification to the network to disable the power saving function.

[0012] In one embodiment of the present invention, when the application processor receives information that the IoT mobile terminal has returned to the idle state after the service operation has ended and has continued for a preset reasonable time, it sends an instruction to the communication processor to enable the power saving function via AT command.

[0013] To achieve the above and other related objectives, this invention provides an automatic control method for the communication processor function of an IoT terminal, applied to the automatic control system of the communication processor function of the IoT terminal. The method includes: acquiring one or more of terminal configuration information, sensor information, or service status information through an application processor; identifying the current application scenario based on built-in automatic control logic; determining the activation timing of the corresponding function of the communication processor; and sending a corresponding function control command to the communication processor via AT commands; receiving and executing the function control command through the communication processor; switching to the corresponding function state; and initiating a registration notification to the network; the functions of the communication processor include: single-mode / multi-mode switching function, positioning function, and power saving function.

[0014] To achieve the above and other related objectives, the present invention provides an Internet of Things (IoT) mobile terminal, comprising: an automatic control system for the communication processor function of the IoT terminal.

[0015] To achieve the above and other related objectives, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method.

[0016] As described above, this invention provides an automatic control system, method, terminal, and medium for the communication processor function of an IoT terminal, offering the following advantages: The application processor side of this invention incorporates scene recognition and automatic control functions. Based on the terminal's product configuration, sensor-collected data, or current business status, it identifies the actual application scenario of the terminal. Based on the recognition results, it automatically enables or disables specific functions of the communication processor by sending control commands to the communication processor and registers the functional status changes with the network side. This invention allows IoT mobile terminals to dynamically adjust the communication processor's operating mode according to the actual application scenario without modifying the communication processor firmware. It enables the effective and rational use of the communication processor's functions by flexibly calling AT commands after automatically identifying various application scenarios, effectively improving the utilization rate of the communication processor's functions, ensuring that various functions are accurately used at appropriate times, and reducing terminal power consumption.

[0028] This invention provides an automatic control system for the communication processor function of an IoT terminal.

Based on the terminal's product configuration, sensor data collection, or current business status, it identifies the actual application scenario of the terminal. Based on the recognition result, it automatically enables or disables specific functions of the communication processor by sending control commands to the communication processor, and registers the functional status changes with the network side.

It enables the effective and reasonable use of the communication processor's functions by flexibly calling AT commands after automatically identifying various application scenarios, effectively improving the utilization rate of the communication processor's functions, ensuring that various functions are used accurately at the appropriate time, and reducing terminal power consumption.

[0029] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can readily implement it. The present invention can be embodied in many different forms and is not limited to the embodiments described herein.

[0030] like Figure 1 This invention presents a schematic diagram of the structure of an automatic control system for the communication processor function of an Internet of Things (IoT) terminal according to an embodiment of the present invention.

[0031] The system includes an application processor (AP) 1 and a communication processor (CP / modem) 2. The application processor 1 is deployed on the main control side of the IoT terminal, responsible for running the operating system, applications, and business logic. The communication processor 2 is deployed on the modem side of the IoT terminal, responsible for the protocol stack and physical layer processing of cellular communication. A communication link is established between the two via a standard AT command interface, enabling downlink transmission of function control commands and uplink feedback of execution status. AT commands are standardized command interaction interfaces between the application processor 1 and the communication processor 2, and between the module and external devices. The AP controls the CP to execute services through AT commands, and the CP actively reports its current status and events to the AP via AT commands.

[0032] Application processor 1 collects multi-dimensional status information in real time via an internal bus or software interface. Specifically, it acquires one or more of the following: terminal configuration information, sensor information, or service status information. This information can be used individually as a basis for scene determination, or it can be weighted and fused to form a comprehensive decision input.

[0033] The automatic control logic built into application processor 1 uses a rule engine, state machine, or lightweight decision model as a carrier to pre-store the mapping relationship between different application scenarios and the functional states of communication processor 2. This logic module analyzes the received multi-source information in real time and identifies the application scenario category of the current terminal by matching preset condition thresholds or pattern features. Then, based on the policy rules corresponding to the scenario category, it determines the activation and deactivation timing of specific functions on the communication processor 2 side. For example, when sensor information indicates that the terminal is in a stationary state and service status information indicates that there is no need for high-bandwidth data transmission, the automatic control logic can determine that the current scenario is suitable for low-power coverage, thereby triggering the activation decision of power-saving functions.

[0034] After determining the functional control requirements, application processor 1 encodes the decision result into a standard AT command format and sends it to communication processor 2 via a serial interface or virtual serial port channel. The sent AT command includes a function identifier, target status parameters, and an optional effective timestamp. Application processor 1 supports sending single commands and also supports sending multiple commands in batches according to a preset order to achieve combined functional control.

[0035] Communication processor 2 continuously monitors the instruction stream from application processor 1. Upon receiving a function control instruction, communication processor 2 executes the instruction. For single-mode / multi-mode switching, the execution unit adjusts the operating mode of the RF front-end, switching between a single network standard and multiple network standards, and reconfigures the baseband processing parameters. For positioning, the execution unit activates or deactivates the Global Navigation Satellite System (GNSS) receiving channel, controlling the download and buffering of assisted positioning data. For power-saving functions, the execution unit adjusts the paging cycle, reduces the RF transmission power level, or enters a discontinuous reception state.

[0036] After completing the functional state switch, the communication processor 2 initiates a registration notification to the mobile communication network based on the new operating state. This registration notification is implemented through standard signaling procedures, such as performing tracking area update or routing area update procedures when the network standard changes, reporting changes in terminal capabilities to the location server when the positioning function is activated, or informing the network side of the current terminal's receive window configuration through specific information elements when the power saving function is enabled. After receiving the registration notification, the network side adjusts its paging strategy, resource scheduling scheme, or location service configuration for the terminal accordingly, thereby ensuring that the state of the network side and the terminal side is synchronized.

[0037] In actual operation, application processor 1 and communication processor 2 form a closed-loop control system. Application processor 1 continuously monitors the terminal's operational status, and upon detecting a scene migration or change in business requirements, it dynamically generates and issues new function control commands. Communication processor 2 responds to the commands in real time, adjusts the function status, and ensures service continuity through network registration notifications. This closed-loop mechanism requires no modification to the underlying firmware of communication processor 2; it relies solely on a standardized AT command interface to achieve on-demand invocation and precise control of modem functions, improving function utilization while reducing overall terminal power consumption.

[0038] In one embodiment, such as Figure 2 In single-mode / multi-mode switching scenarios, after the IoT mobile terminal is powered on, the application processor (AP) first reads the product's factory configuration, identifies the current terminal as a wireless fixed-line product, and obtains the corresponding configuration parameters. The communication processor (CP / modem) automatically searches for and camps on a 5G network cell with stable signal and good quality. Subsequently, it reports the 5G network cell camping status to the application processor via AT commands, namely the 5G cell signal strength, tracking area code, and cell identification information.

[0039] Based on the terminal configuration information read and the 5G network cell camping status reported by the communication processor, application processor 1 runs its built-in automatic control logic to determine that the current IoT mobile terminal is in an application scenario requiring a stable network camping environment. This determination condition includes the terminal configuration information specifying priority use of the 5G network and the 5G cell signal quality meeting the camping threshold.

[0040] After confirming the need for a stable camping environment, the application processor sends a 5G Only mode configuration command to the communication processor via the AT command interface. The communication processor receives and executes this setting, enabling the 5G Only single-mode function. After completing the function state switch, the communication processor performs the initial registration process based on the currently camped 5G network cell. The communication processor accesses the 5G cell through a random access channel and sends a non-access stratum registration request message to the network side, carrying the terminal identifier, security parameters, and network capability information. After successful authentication by the network side, the communication processor completes the initial registration on the 5G network and reports the registration success status to application processor 1.

[0041] Through the above implementation method, the application processor can automatically make decisions and forcibly lock onto the 5G single-mode network during the power-on stage of the IoT mobile terminal, avoiding frequent changes in network standard during the multi-mode network search process, thereby establishing a stable network dwell environment, reducing power consumption in the initial access stage and improving communication reliability.

[0042] In this embodiment, the application processor continuously monitors the signal quality of the 5G network in real time during terminal operation. The application processor periodically retrieves the current serving cell signal parameters reported by the communication processor via status query commands, including indicators such as reference signal received power, reference signal received quality, and signal-to-noise ratio (SNR). The application processor compares these real-time parameters with preset threshold values. When it detects that the reference signal received power is continuously below the weak coverage threshold, or the SNR deteriorates to an unacceptable range for communication quality, and this state persists for more than a preset time window, the application processor determines that the current 5G network can no longer provide stable and reliable communication services. At this time, the application processor sends a mode deactivation command to the communication processor to disable the 5G-only single-mode function and restore the communication processor's multi-mode operation capability.

[0043] In one embodiment, such as Figure 3In a location-based scenario, the application processor (AP) interacts with the communication processor (CP / modem). The application processor receives status monitoring information from sensors such as the terminal's built-in accelerometer or gyroscope. When the terminal remains stationary for an extended period, the location function is disabled by default to reduce power consumption. When the built-in sensors detect a change in the terminal's geographic location, they report the motion event to the application processor. The application processor continuously monitors and analyzes the motion data. Once it confirms the movement, it determines that the terminal has entered a scenario requiring location services and sends a command to the communication processor to enable the location function via AT commands. Upon receiving this command, the communication processor activates the location baseband and related radio frequency receiving resources, completes the initial configuration of the location module, and then initiates a registration update process with the mobile network, marking the location function as enabled in the terminal's capability information. After receiving this update, the network configures or activates location-related service channels for the terminal. At this point, the location function enters normal operating mode, and the terminal can respond to location-related service requests such as emergency calls, location reporting, or trajectory tracking.

[0044] During positioning operation, sensors continuously collect terminal motion data. When the sensors detect that the terminal has returned to a stationary state from a moving state, they report this change to the application processor. Upon confirming the stationary state, the application processor determines that maintaining positioning is no longer necessary. At this point, the application processor sends a command to the communication processor to disable the positioning function via AT commands. The communication processor executes this command, shutting down the positioning baseband and cutting off related radio frequency receiving resources, releasing the memory and computing resources occupied by positioning, and then initiating a registration update process with the network to notify the network that the positioning function has been disabled. The network deletes positioning-related configurations for the terminal or deactivates positioning-related service channels, and the terminal returns to a low-power, stationary standby state.

[0045] This dynamic control mechanism, based on motion perception and duration determination, effectively avoids ineffective positioning power consumption when used in fixed locations, and promptly restores positioning capability when the terminal's location changes, achieving a balance between functional availability and terminal energy efficiency.

[0046] In a preferred embodiment, such as Figure 3When the application processor receives information from the sensor that the IoT mobile terminal has returned to a stationary state from a moving state for a preset reasonable time, it sends an AT command to the communication processor to disable the positioning function. The preset reasonable time is set according to requirements. This design introduces a preset reasonable time delay after the terminal changes from moving to stationary, avoiding frequent switching of the positioning function due to brief periods of stillness or environmental fluctuations. Compared to solutions that immediately disable the positioning function after a state change, this preferred embodiment effectively reduces frequent interactions of network-side registration update signaling, lowers the processing load of the communication processor and network resource consumption, and prevents the adverse effects of repeated start-ups and shutdowns of positioning-related services on system stability. Therefore, while ensuring the timeliness of positioning services, it further improves the battery life and operational reliability of the IoT mobile terminal.

[0047] In one embodiment, such as Figure 4 In power-saving switching scenarios, after an IoT terminal completes its current service data transmission, releases its service bearer, and returns to an idle state, the communication processor (CP / modem) continuously monitors the activity of the data channel and signaling plane. If it returns to an idle state, the application processor (AP) determines that it does not need to maintain full-function reception capability at present, and then sends a command to the communication processor (CP / modem) to enable the power-saving function via AT commands. After receiving the command, the communication processor configures low-power operating parameters, initiates power-saving mechanisms such as extending the paging cycle or entering deep sleep, and then initiates a registration update process with the mobile network to mark the power-saving function as enabled in the terminal capability information or protocol cells. After receiving the update, the network side adjusts the paging strategy, downlink data buffering mechanism, or session management parameters accordingly to adapt to the terminal's low-power reception mode and reduce unnecessary paging resource consumption on the network side.

[0048] When an IoT terminal is idle and its power-saving function is enabled, if the application processor detects a new service initiation, such as a voice call request, sensor-triggered data reporting, or connection establishment initiated by an upper-layer application, the application processor immediately sends an AT command to the communication processor to disable the power-saving function. The communication processor responds to this command, exits low-power mode, resumes its normal paging listening cycle and RF receive configuration, rebuilds its always-on service ready state, and initiates a registration update process with the network, notifying the network that the power-saving function has been disabled. The network then restores its standard paging and instant downlink data transmission mechanisms, ensuring a delay-free response and normal establishment of new services.

[0049] This service-state-aware, dynamic power-saving control mechanism achieves low-power state synchronization between the terminal and network sides through the coordinated operation of the application processor and the communication processor. It promptly activates the power-saving function when services are idle to reduce terminal energy consumption and network paging load, and quickly deactivates the function when new services arrive to ensure service establishment latency and communication reliability, thus achieving an effective balance between power optimization of IoT terminals and service real-time performance.

[0050] In a preferred embodiment, the application processor continuously monitors the upper-layer service status of the IoT mobile terminal. When the service ends and the terminal returns to an idle state, and this idle state lasts for a preset reasonable time, the application processor determines that there is currently no immediate service demand. The preset reasonable time is set according to demand. At this time, the application processor sends a command to the communication processor via AT commands to enable the power-saving function. After receiving the command, the communication processor executes the corresponding low-power mode configuration, such as extending the paging cycle or adjusting the radio frequency monitoring strategy, and registers and updates the terminal's current power consumption status with the mobile network. The network side performs paging and resource scheduling on the terminal based on the updated parameters, thereby reducing the terminal's energy consumption during idle periods while ensuring service accessibility. This mechanism achieves coordinated linkage between service status and power management, avoiding the terminal maintaining high-power monitoring during ineffective idle periods, and significantly improving the battery life and energy utilization efficiency of IoT terminals.

[0051] Similar to the principles of the above embodiments, the present invention provides an automatic control method for the communication processor function of an Internet of Things (IoT) terminal.

[0052] The following specific embodiments are provided in conjunction with the accompanying drawings:

[0053] like Figure 5 This is a flowchart illustrating an automatic control method for the communication processor function of an IoT terminal according to an embodiment of the present invention. Applied to the automatic control system for the communication processor function of the IoT terminal described in the above embodiment, the method includes:

[0054] Step S1: Obtain one or more of the terminal configuration information, sensor information, or service status information through the application processor, identify the current application scenario based on the built-in automatic control logic, determine the activation timing of the corresponding function of the communication processor, and send the corresponding function control command to the communication processor through AT commands.

[0055] Step S2: Receive and execute the function control command through the communication processor, switch to the corresponding function state, and initiate a registration notification to the network; the functions of the communication processor include: single-mode / multi-mode switching function, positioning function, and power saving function;

[0056] Since the implementation principle of the automatic control method for the communication processor function of the Internet of Things terminal has been described in the foregoing embodiments, it will not be repeated here.

[0057] like Figure 6 This invention illustrates a schematic diagram of an IoT mobile terminal according to an embodiment of the present invention. The terminal includes an automatic control system for the communication processor function of the IoT terminal. The application processor establishes a data connection with the communication processor for bidirectional interaction and collaborative control via commands. By deeply collaborating between the application processor and the communication processor and introducing the automatic control system for the communication processor function, this IoT mobile terminal achieves intelligent closed-loop control of power consumption management and network access, significantly improving the terminal's operating efficiency and reliability in complex IoT scenarios. Regarding power consumption, after a preset period of idle time, the application processor automatically triggers the power-saving mechanism of the communication processor. The communication processor enters a low-energy state by extending the paging cycle, effectively reducing standby current and overall power consumption, significantly extending the terminal's battery life in battery-powered or remotely deployed scenarios, and reducing energy consumption and maintenance frequency. Regarding network performance, after the terminal is powered on, the application processor can automatically identify service types such as wireless fixed-line phones based on configuration information, and intelligently determine and force a switch to 5G Only mode after the communication processor reports the 5G camping status. This mechanism ensures that the terminal obtains stable network camping within 5G coverage areas, avoiding unnecessary network fallback. Regarding positioning functionality, when a sensor detects that an IoT mobile terminal has moved while stationary, the application processor sends a positioning function activation command to the communication processor via AT commands. Upon receiving this command, the communication processor enables the positioning function, initiates an update registration with the network to notify that the positioning function is enabled, and then operates positioning-related services normally. When a sensor detects that the IoT mobile terminal has returned to a stationary state from a moving state, the application processor sends a positioning function deactivation command to the communication processor via AT commands. Upon receiving this command, the communication processor deactivates the positioning function and initiates an update registration with the network to notify that the positioning function is deactivated.

[0058] Overall, this IoT mobile terminal enhances the reliability, battery life, and deployment adaptability of IoT terminals through its network adaptive, energy consumption self-optimization, and location controllable design.

[0059] The IoT mobile terminal provided in this invention can be a mobile phone, computer device, tablet device, personal digital processing device, factory back-end processing device, etc. Those skilled in the art will understand that all or part of the steps of the above method embodiments can be implemented by computer program-related hardware. The aforementioned computer program can be stored in a computer-readable storage medium. When the program is executed, it performs the steps of the above method embodiments; and the aforementioned storage medium includes various media capable of storing program code, such as ROM, RAM, magnetic disk, or optical disk.

[0060] In the embodiments provided in this application, the computer-readable and writable storage medium may include read-only memory, random access memory, EEPROM, CD-ROM or other optical disc storage devices, disk storage devices or other magnetic storage devices, flash memory, USB flash drive, portable hard drive, or any other medium capable of storing desired program code in the form of instructions or data structures and accessible by a computer. Additionally, any connection may be appropriately referred to as a computer-readable medium. For example, if instructions are transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. However, it should be understood that computer-readable and writable storage media and data storage media do not include connections, carrier waves, signals, or other transient media, but are intended for non-transient, tangible storage media. The disks and optical discs used in the application include compact optical discs (CDs), laser optical discs, optical discs, digital multifunction optical discs (DVDs), floppy disks, and Blu-ray discs, where disks typically copy data magnetically, while optical discs use lasers to copy data optically.

[0061] In summary, the IoT terminal communication processor function automatic control system, method, terminal, and medium of the present invention have built-in scene recognition and automatic control functions on the application processor side. Based on the terminal product configuration, sensor data collection, or current business status, the system identifies the actual application scenario of the terminal. Based on the recognition result, it automatically enables or disables specific functions of the communication processor by sending control commands to the communication processor and registers the functional status changes with the network side. This invention enables IoT mobile terminals to dynamically adjust the working mode of the communication processor according to the actual application scenario without modifying the communication processor firmware. It achieves effective and reasonable use of the communication processor's functions by flexibly calling AT commands after automatically identifying various application scenarios, effectively improving the utilization rate of the communication processor's functions, ensuring that various functions are used accurately at the appropriate time, and reducing terminal power consumption. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
