Description

Technical Field

[0001] This invention belongs to the field of 5G communication technology, and more specifically relates to a method, system, device and medium for dynamic switching of mobile terminal signal reception mode. Background Technology

[0002] 5G NR broadcast, as a new generation of broadcast technology based on native 5G networks, demonstrates significant advantages in large-scale, high-quality content distribution due to its characteristics of "no SIM card, no data usage, and cross-carrier compatibility" and its integrated "communication network + broadcast network" architecture. It supports flexible switching between broadcast / multicast and unicast modes and can achieve efficient utilization of network resources through differentiated resource allocation strategies, becoming an important technical path for mobile terminals to receive multimedia information. As the core receiving carrier of 5G NR broadcast, the adaptability of the mobile terminal's signal reception mode directly determines the user's experience quality for services such as high-definition video and emergency broadcasts. Especially in scenarios where communication resources are dynamically changing, the timeliness and accuracy of mode switching are crucial.

[0003] However, current 5G NR broadcast technology is still in the prototype development and technology verification stage. Although terminal devices have basic reception capabilities in broadcast / multicast / unicast modes, the mode switching mechanism has significant limitations. In existing technologies, mode switching relies entirely on manual operation by the user, who must manually select and switch to the corresponding mode based on subjective perception (such as signal lag, data consumption prompts) or changes in the scenario (such as entering a signal dead zone). This approach not only places high demands on the user's technical knowledge but also suffers from response lag—when network conditions suddenly deteriorate (such as a sharp drop in signal strength or a sudden increase in latency) or the terminal moves at high speed, the user often cannot complete the switching operation in real time, leading to signal interruption, content lag, and other problems, seriously affecting reception continuity.

[0004] Furthermore, manual mode switching cannot adapt to dynamically changing network environments and terminal states, resulting in low network resource utilization efficiency. Broadcast / multicast mode enables concurrent reception by multiple terminals through shared channel resources, making it suitable for large-scale content distribution in static or low-speed scenarios; while unicast mode uses dedicated resource allocation, making it more suitable for high-speed mobile or personalized service needs. When communication resources are scarce, if a terminal continues to occupy broadcast / multicast channels due to failure to switch modes in time, it will waste resources and affect the reception quality of other terminals; conversely, if unicast mode is maintained when broadcast / multicast channels are available, it will increase user traffic consumption and operator network load. This mismatch between resource allocation and scenario requirements has become a key bottleneck restricting the practical application and productization of 5G NR broadcast technology.

[0005] Furthermore, existing terminals lack the ability to coordinate their own mobility status with network parameters, making it difficult to accurately trigger mode switching. When terminals are moving at high speeds (such as in high-speed rail or automobiles), network signal strength, latency, and other parameters fluctuate rapidly with changes in location. In such cases, the stability of broadcast / multicast modes is easily affected by factors such as the Doppler effect. In static or low-speed scenarios, the resource consumption disadvantage of unicast mode is even more pronounced. Since existing technologies have not established a linkage mechanism between network status (signal strength, latency) and terminal status (movement speed), relying solely on manual switching by the user inevitably leads to a disconnect between mode selection and actual needs, failing to guarantee smooth signal reception in complex scenarios. Summary of the Invention

[0006] To address the above problems, the present invention aims to provide a method, system, device, and medium for dynamic switching of mobile terminal signal reception modes. This method utilizes 5G SOC chip initialization configuration, real-time monitoring of network status by the communication baseband, and acquisition of terminal reference speed by GPS or inertial sensors. It also relies on the MBS scheduling module to achieve automatic mode switching, thereby ensuring efficient utilization of network resources while improving the continuity, scenario adaptability, and user experience of mobile terminal signal reception.

[0007] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, embodiments of this application provide a method for dynamically switching signal reception modes of a mobile terminal, including: Send commands to the 5G SOC chip protocol stack interface to initialize the chip and load configuration parameters; Activate the communication baseband module within the 5G SOC chip, start a broadcast or multicast session, and receive signals; The network status information is monitored in real time using the communication baseband of the 5G SOC chip; the network status information includes network signal strength, network type, and latency information. The GPS module is called to receive satellite signals to calculate position and time in order to calculate real-time speed, or the inertial sensor is called to detect acceleration and perform integration to obtain the moving speed and generate a reference speed. The signal reception mode is dynamically switched based on network signal strength, delay information, or reference speed.

[0008] In an optional implementation, issuing instructions to the 5G SOC chip protocol stack interface to initialize the chip and load configuration parameters includes: Generate an initialization instruction set and transmit the initialization instructions to the protocol stack interface of the 5G SOC chip via the SPI interface or communication bus; Perform hardware reset and initial boot according to initialization instructions; Read the boot code from the storage medium and load the boot code into the memory of the 5G SOC chip; The configuration file is loaded, and the configuration parameters in the configuration file are parsed by the 5G SOC chip. The communication frequency band, modulation and demodulation method, and signal processing algorithm are set through the configuration parameters.

[0009] In an optional implementation, activating the communication baseband module within the 5G SOC chip, initiating a broadcast or multicast session, and receiving signals includes: The communication baseband module inside the 5G SOC chip is activated by software control signals. Activate the analog-to-digital converter and digital down-conversion unit built into the 5G SOC chip; Initialize the control interface for interaction between the baseband and RF sections, and set the relevant registers to ensure that the baseband processor can accurately send control commands to the RF front end; By utilizing the power management module inside the 5G SOC chip, a stable operating voltage is provided to the communication baseband module, enabling it to enter a normal working state; Based on the configuration information, construct a broadcast or multicast session request; The session request carries the terminal device's identification information and relevant parameters of the broadcast or multicast service to be received, and interacts with the backend service platform through the 5G core network base station to establish a session connection; During signal reception, the received signal is processed sequentially using the baseband signal processing flow, including filtering, demodulation, channel estimation, equalization, and decoding. This process converts the original baseband signal into recognizable data information, which is then transmitted to the application processor of the terminal device via the chip's internal data bus.

[0010] In an optional implementation, the real-time monitoring of network status information using the communication baseband of the 5G SOC chip includes: The power of the received radio frequency signal is detected by the signal strength detection circuit inside the communication baseband; the detected power value is compared with the preset signal strength threshold and converted into the corresponding signal strength level information to quantitatively represent the cellular network signal strength. By analyzing the received system broadcast messages through the communication baseband, network type identification information is extracted to determine whether the current network is a 5G network, a 4G network, or another type of network, thus identifying the network type. The network latency is calculated by sending specific test data packets using the communication baseband and recording the time difference between sending and receiving the corresponding response data packet.

[0011] In an optional implementation, the step of calling the GPS module to receive satellite signals to calculate position and time to calculate real-time velocity, or calling the inertial sensor to detect acceleration and perform integration to obtain moving velocity, and generating a reference velocity, includes: The GPS module is invoked to receive satellite signals, and the received satellite signals are processed by the built-in processor of the GPS module to obtain the location coordinates and corresponding time information of the terminal device. Within a preset time interval, read the current position coordinates, the previous position coordinates, and the corresponding time. Through formula V Calculate the moving speed V of the mobile terminal within the preset time interval; where (x2, y2) is the position coordinate at the current time, t2 is the time at the current time, (x1, y1) is the position coordinate at the previous time, and t1 is the time at the previous time. The moving speed V is used as the reference speed.

[0012] In an optional implementation, the step of calling the GPS module to receive satellite signals to calculate position and time to calculate real-time velocity, or calling the inertial sensor to detect acceleration and perform integration to obtain moving velocity, and generating a reference velocity, includes: The acceleration of the mobile terminal in three-dimensional coordinates is detected in real time using an inertial sensor. Obtain the acceleration of the mobile terminal in the three coordinate axes of the three-dimensional coordinate system within the time interval [t0, t0+Δt]. The moving speed v of the mobile terminal within the time interval [t0, t0+Δt] can be calculated using the following formula:

[0013] in, , , These represent the accelerations of the mobile terminal along the x, y, and z axes, respectively. , , These represent the initial velocities of the mobile terminal in the x, y, and z axes at the initial time point t0, respectively. The moving speed v is used as the reference speed.

[0014] In an optional implementation, the step of dynamically switching the signal reception mode based on network signal strength, delay information, or reference speed includes: When the network signal strength is lower than the preset strength threshold, the MBS scheduling module generates an instruction to close the broadcast or multicast session, stops channel monitoring, and switches the signal reception mode to unicast mode. When the delay information is higher than the preset delay threshold, the MBS scheduling module generates an instruction to close the broadcast or multicast session, stops channel monitoring, and switches the signal reception mode to unicast mode. When the reference speed is higher than the preset speed limit, the MBS scheduling module generates an instruction to close the broadcast or multicast session, stops channel monitoring, and switches the signal reception mode to unicast mode.

[0015] Secondly, embodiments of this application also provide a mobile terminal signal reception mode dynamic switching system, comprising: The initialization module is used to issue commands to the 5G SOC chip protocol stack interface to initialize the chip and load configuration parameters. The session initiation module is used to activate the communication baseband module within the 5G SOC chip, initiate a broadcast or multicast session, and receive signals. The network status monitoring module is used to monitor network status information in real time using the communication baseband of the 5G SOC chip; the network status information includes network signal strength, network type, and latency information. The motion status monitoring module is used to call the GPS module to receive satellite signals to calculate position and time in order to calculate real-time speed, or to call the inertial sensor to detect acceleration and perform integration to obtain motion speed and generate reference speed; The signal reception mode switching module is used to dynamically switch the signal reception mode based on network signal strength, delay information, or reference speed.

[0016] Thirdly, embodiments of this application also provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the mobile terminal signal receiving mode dynamic switching method as described in any of the above.

[0017] Fourthly, embodiments of this application also provide a storage medium storing a computer program thereon, wherein the computer program, when executed by a processor, implements the steps of the mobile terminal signal receiving mode dynamic switching method as described in any of the above claims.

[0018] As can be seen from the above technical solutions, the present invention has the following advantages: The mobile terminal signal reception mode dynamic switching method provided in this application achieves dynamic switching of the mobile terminal signal reception mode by initializing and configuring the 5G SOC chip and activating the communication baseband module, combined with real-time network status information (signal strength, network type, latency) monitored by the communication baseband and the terminal reference speed generated based on GPS or inertial sensors. This application eliminates the need for manual user operation and automatically switches between broadcast / multicast and unicast modes based on network quality and terminal mobility. This ensures efficient utilization of broadcast / multicast resources in static or low-speed scenarios, while switching to unicast mode in weak signal, high latency, or high-speed movement scenarios ensures the continuity and smoothness of signal reception. This effectively improves the productization level and user experience of 5G NR broadcast terminals, while also optimizing network resource allocation efficiency.

[0019] This application eliminates the need for manual user operation. By monitoring network status and terminal mobility in real time, it automatically switches between broadcast / multicast and unicast modes, avoiding signal interruptions and content stuttering caused by delayed user operation. This significantly improves the continuity and smoothness of signal reception and lowers the barrier to entry for users.

[0020] This application addresses the differences in resource allocation between broadcast / multicast mode (suitable for large-scale concurrent reception) and unicast mode (suitable for personalized and high-stability requirements). By dynamically switching between them, it achieves precise resource adaptation, reduces ineffective occupation when communication resources are scarce, ensures the efficiency of multi-terminal sharing of broadcast / multicast resources, avoids resource waste in unicast mode, and improves the overall network resource utilization rate.

[0021] This application combines multiple parameters such as network signal strength, latency information, and terminal movement speed to trigger switching. In complex environments such as weak signal, high latency, or high-speed movement (such as high-speed rail and automobile scenarios), it automatically switches to unicast mode to ensure signal reception quality; in static or low-speed scenarios with good network conditions, it maintains broadcast / multicast mode to ensure reception stability in different scenarios.

[0022] This application establishes a complete dynamic switching solution by standardizing the 5G SOC chip initialization, parameter configuration, and baseband signal processing flow, combined with a multi-sensor data fusion state judgment mechanism. This solution addresses the technical shortcomings of existing 5G NR broadcast terminals in mode switching, and promotes the terminal's progress from the prototype verification stage to practical application and productization.

[0023] This application integrates multiple components such as the 5G SOC chip protocol stack, communication baseband, GPS, inertial sensor and MBS scheduling module to work together, realizing closed-loop control of the entire process from chip initialization, signal reception, status monitoring to mode switching, improving the coordination efficiency of terminal hardware and software, and laying the terminal technology foundation for the large-scale application of 5G NR broadcast technology.

[0028] The various embodiments of this disclosure will be described more fully in the following detailed description of the specific steps of the method for dynamically switching the signal reception mode of a mobile terminal. This disclosure may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this disclosure to the specific embodiments disclosed herein, but rather this disclosure should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this disclosure.

[0030] 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.

[0031] Please see Figure 1The diagram shows a flowchart of a method for dynamically switching the signal reception mode of a mobile terminal in a specific embodiment. The mobile terminal is a 5G NR broadcast information receiving device, and the mobile terminal is equipped with a 5G SOC chip, a GPS module, and an inertial sensor.

[0032] The method includes the following steps: S1: Issues instructions to the 5G SOC chip protocol stack interface to initialize the chip and load configuration parameters.

[0033] In a specific implementation, the control unit of the mobile terminal generates a specific set of initialization instructions. These instructions conform to the protocol specifications supported by the 5G SOC chip, for example, they can utilize the AT instruction set (according to 3GPP Spec27.007 and other related standards), and be constructed with "AT" as a prefix.

[0034] The initialization instructions include various parameter settings for chip initialization, such as configuration related to specifying the chip's operating mode as 5GNR broadcast mode, and path information for loading configuration files. These instructions are accurately transmitted to the protocol stack interface of the 5G SOC chip via the device's internal data transmission channels, such as the SPI (Serial Peripheral Interface) interface or a specific inter-chip communication bus.

[0035] When the 5G SOC chip receives the initialization command, its internal logic circuits begin to respond. First, a hardware reset and initial boot are performed. The program counter points to a specific reset vector address (such as the common address 0x00000000), and each hardware module enters its initial default state. Then, boot code is read from non-volatile memory (such as built-in Flash memory) according to the storage medium characteristics and interface specifications (e.g., the communication protocol followed during eMMC boot) and loaded into the chip's internal memory area, preparing for subsequent initialization. During the system core initialization phase, the clock source is determined based on the chip design and application requirements. The clock divider coefficient is set by configuring the registers of the clock management unit to adjust the clock frequency of each module. Simultaneously, the internal SRAM and external DRAM are initialized, memory timing parameters are set to match hardware characteristics, and memory areas are allocated for code, data, and stack storage. When loading the configuration file, the chip parses the parameters in the configuration file. These parameters cover communication frequency band settings, modulation / demodulation method selection, signal processing algorithm configuration, etc., thereby completing the chip's initialization settings and putting it into a working state.

[0036] S2: Activate the communication baseband module within the 5G SOC chip, start a broadcast or multicast session, and receive signals.

[0037] In a specific implementation, after the 5G SOC chip is initialized, the communication baseband module inside the chip is activated via software control signals. Activation of the communication baseband module involves the coordinated startup of multiple sub-modules. First, the basic modules for baseband signal processing, such as the analog-to-digital converter (ADC) unit and the digital down-conversion (DDC) unit, are started to prepare for subsequent signal processing. Simultaneously, the control interface for interaction between the baseband and radio frequency (RF) sections is initialized, and relevant registers are set to ensure that the baseband processor can accurately send control commands to the RF front-end, such as adjusting the frequency synthesizer and controlling the gain of the power amplifier, and can receive signal status information from the RF front-end. Through the chip's internal power management module, a stable operating voltage is provided to the communication baseband module, enabling it to enter normal operating condition and prepare for signal reception.

[0038] After the communication baseband is enabled, a broadcast or multicast session request is constructed based on the configuration information. The request carries the terminal device's identification information and relevant parameters of the desired broadcast or multicast service (such as service ID, data stream format, etc.). A session connection is established by interacting with the backend service platform through the 5G core network base station. Once the session is successfully established, the communication baseband begins listening to the corresponding 5G NR broadcast channel to receive broadcast or multicast signals. During signal reception, the received signal is processed sequentially using the baseband signal processing flow, including filtering, demodulation, channel estimation, equalization, and decoding, converting the original baseband signal into recognizable data information. This data is then transmitted to the terminal device's application processor via the chip's internal data bus for further processing.

[0039] S3: Real-time monitoring of network status information using the communication baseband of the 5G SOC chip; the network status information includes network signal strength, network type, and latency information.

[0040] In a specific implementation, the network status is continuously monitored using the communication baseband. Regarding cellular network signal strength monitoring, the power of the received radio frequency signal is detected by a signal strength detection circuit within the baseband. The detected power value is compared with a preset signal strength threshold and converted into corresponding signal strength level information, such as the common RSSI (Received Signal Strength Indicator) value, to quantify the cellular network signal strength.

[0041] For network type monitoring, the baseband analyzes the received system broadcast messages (such as MIB, SIB, etc. messages in 5G networks), extracts network type identification information from them, and determines whether the current network is a 5G network, a 4G network, or another type of network.

[0042] In terms of latency monitoring, the baseband calculates network latency by sending specific test data packets and recording the time difference between sending and receiving the corresponding response data packet. For example, it periodically sends ICMP (Internet Control Message Protocol) echo request packets to the base station, calculates the round-trip time (RTT) based on the time it takes to receive the echo response data packet, and stores this network status data in real time in the chip's internal cache area for subsequent analysis.

[0043] S4: Call the GPS module to receive satellite signals to calculate position and time in order to calculate real-time speed, or call the inertial sensor to detect acceleration and perform integration to obtain the moving speed and generate a reference speed.

[0044] In this specific implementation, the reference velocity is generated in two ways, as follows: 1. Use GPS positioning signals to calculate position changes and time differences to obtain real-time speed, which can be used as a reference speed.

[0045] First, the mobile terminal's GPS module continuously receives satellite signals. The GPS module's built-in processor processes the received satellite signals to obtain the terminal device's geographical coordinates (such as longitude and latitude) and corresponding time information. Within a certain time interval (e.g., every second), it reads the current location coordinates, the previous location coordinates, and the corresponding time.

[0046] Then, through formula V Calculate the moving speed V of the mobile terminal within the preset time interval; where (x2, y2) is the position coordinate at the current time, t2 is the time at the current time, (x1, y1) is the position coordinate at the previous time, and t1 is the time at the previous time.

[0047] Finally, the calculated mobile speed V is used as a reference speed and transmitted to the 5G SOC chip through the data interface inside the mobile terminal (such as the I2C interface) so that it can be comprehensively analyzed together with the network status data.

[0048] 2. Use the inertial sensor to detect the terminal's acceleration, and obtain the moving speed through integration, which is then used as a reference speed.

[0049] First, the mobile terminal's built-in inertial sensors (such as accelerometers) detect the terminal's acceleration values ​​in real time along three coordinate axes (x, y, and z). The accelerometer converts the detected analog acceleration signals into digital signals for output. The 5G SOC chip reads this acceleration data through a specific sensor interface (such as an SPI interface connected to the accelerometer).

[0050] At the software level, an integral algorithm is used to integrate the acceleration to obtain the velocity.

[0051] Specifically, the acceleration of the mobile terminal in the three coordinate axes of the three-dimensional coordinate system is obtained within the time interval [t0, t0+Δt]. The moving speed v of the mobile terminal within the time interval [t0, t0+Δt] can be calculated using the following formula:

[0052] in, , , These represent the accelerations of the mobile terminal along the x, y, and z axes, respectively. , , These represent the initial velocities of the mobile terminal in the x, y, and z axes, respectively, at the initial time point t0.

[0053] It should be noted that, during the integration process, considering factors such as sensor noise and drift, a digital filtering algorithm (such as the Kalman filter algorithm) is used to preprocess the acceleration data to improve the accuracy of velocity calculation.

[0054] Finally, the moving speed v is used as a reference speed and fed back in real time to the relevant processing module of the 5G SOC chip for joint analysis with network status data.

[0055] S5: Dynamically switch signal reception modes based on network signal strength, delay information, or reference speed.

[0056] In a specific implementation, the 5G SOC chip transmits real-time monitored network status data (such as signal strength below a preset threshold or latency exceeding a set maximum latency time) and calculated reference speed (such as speed exceeding a set speed limit) to the terminal MBS scheduling module. The decision algorithm within the MBS scheduling module comprehensively analyzes and judges this data. When switching conditions such as poor network signal (e.g., RSSI value below -100dBm), high latency (e.g., RTT greater than 100ms), or high mobile speed (e.g., reference speed greater than 60km / h) are met, the MBS scheduling module generates a command to close the broadcast / multicast session. This command is sent to the communication baseband module through the chip's internal control signal channel. The communication baseband module executes the corresponding operation, stopping monitoring the broadcast / multicast channel and releasing relevant session resources. Simultaneously, the MBS scheduling module generates configuration information for switching to unicast mode, including parameter settings required for unicast communication (e.g., target server address, port number, communication protocol, etc.). This configuration information is transmitted to the communication baseband module through the device's internal data transmission channel. Based on the configuration information, the communication baseband module rebuilds the unicast connection with the target server and begins to receive signals in unicast mode, ensuring that the terminal device can still receive data stably in complex network environments.

[0057] In this embodiment, by initializing and configuring the 5G SOC chip and activating the communication baseband module, the communication baseband monitors network signal strength, latency, and other status information in real time. Combined with the terminal reference speed generated by GPS or inertial sensors, the MBS scheduling module automatically switches between broadcast / multicast and unicast modes. This not only eliminates the hassle of manual operation for users and avoids signal problems caused by operational delays, thus improving the user experience, but also accurately adapts the communication mode according to network conditions and terminal mobility. While ensuring efficient utilization of broadcast / multicast resources in static or low-speed scenarios, it also ensures reception stability in scenarios with weak signals, high latency, or high-speed movement, optimizing network resource allocation, further promoting the productization process of 5G NR broadcast terminals, and enhancing the efficiency of multi-module collaborative work within the terminal.
