[0001] The invention belongs to the field of communications, and in particular relates to a SCA radio station system and an upgrading method based on a smart deployment module. Background Art

[0002] At present, to upgrade a traditional radio station to a soft wireless radio station, the current soft wireless system deployment mode requires system adaptation, software embedding, waveform transplantation, and system transplantation of the traditional radio system, which will inevitably increase the workload for radio manufacturers and bring unstable variables to the development of new models. Moreover, each time new requirements are added to the soft wireless system, problems are iterated, and functions are upgraded, the work of full system adaptation, transplantation, and embedding will be repeated, and new unpredictable system variables will be introduced. Therefore, we lack an intermediate state between the soft wireless system verification stage and the mature and comprehensive deployment stage of the soft wireless system. The patent provides an SCA radio system and upgrade method based on a smart deployment module, which has a flexible access method with the traditional system and a clear boundary with the traditional system. When upgrading and transforming the soft wireless system, it will not affect the traditional system as much as possible and has flexible and diverse functional expansion capabilities. Summary of the invention

[0003] The purpose of the present invention is to provide an SCA radio system and an upgrade method based on a smart deployment module, aiming to provide a flexible access method for upgrading a traditional radio station to a soft radio station.

[0006] Furthermore, the radio system includes a host computer, an ARM chip, a radio frequency chip, an FPGA chip and a smart deployment module, and the radio system upgrade method is as follows: (1) the smart deployment module activates the universal driver when the system is powered on; (2) the universal driver sends a request to start the SCA system to the host computer main control software; (3) after the main control software responds with consent, the universal driver loads and starts the dedicated driver on the ARM chip; (4) the dedicated driver loads the SCA operating system components, SCA waveform and management system on the ARM chip; the SCA waveform covers the FPGA software.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] First, some terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0027] Terminal device: can be a mobile terminal, fixed terminal or portable terminal, such as a mobile phone, node, unit, device, multimedia computer, multimedia tablet, Internet node, communicator, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system device, personal navigation device, personal digital assistant, audio / video player, digital camera / camcorder, positioning device, television receiver, radio broadcast receiver, e-book device, gaming device or any combination thereof, including accessories and peripherals of these devices or any combination thereof. It is also foreseeable that the terminal device can support any type of interface for the user (such as wearable devices), etc.

[0028] The Software Communication Architecture (SCA) is an open framework that defines how software and hardware components can interoperate in a software-defined radio. It defines several interfaces that a compliant application must implement. The SCA Core Framework (CF) is a standard component management API that enables interoperability between radios; SDR software can be ported between different CF-compliant hardware sets.

[0029] See also Figure 1 , Figure 2 As shown, it is a structure diagram of the SCA radio system and a function module calling relationship diagram provided in an embodiment of the present application.

[0030] The SCA radio system provided in the embodiment of the present application includes a host computer, an ARM chip, a radio frequency chip, an FPGA chip and a smart deployment module. The smart deployment module is separable from the SCA radio system. The smart deployment module includes a general driver, a dedicated driver, an SCA operating system component, an SCA waveform and management system. The host computer is provided with a main control software, the ARM chip is provided with an embedded software, and the FPGA chip is provided with an FPGA software.

[0031] Host computer is a term widely used in automation control systems, usually referring to a computer system used to monitor and control the lower computers (such as PLC, single-chip microcomputer, etc.). The host computer communicates with the lower computers through specific communication protocols (such as RS232, RS485, Ethernet, etc.), obtains the operating status of the lower computers, sends control commands, and is responsible for data processing, storage and display, as well as interaction with other systems.

[0032] The soft universal driver mainly implements the module interface driver program. It starts working when the module is powered on or connected to the system, and guides the system to load the dedicated driver.

[0033] The dedicated driver initializes the soft environment and takes over the hardware resources of the radio system. The original program of the radio will exit the kernel, and the SCA-related files will be copied to the system, waiting for the system management to install the waveform.

[0034] System management mainly implements the deployment management and health management of SCA waveforms.

[0035] The SCA operating system component provides the environment and interface for SCA waveform deployment and operation.

[0036] ‌Master control software is software used to manage, monitor and control the operating status of network equipment, and realize the control and management of network elements by the network management system. The master control software includes a human-machine interface, which realizes the interface to the ARM chip, parameter distribution configuration, status upload display, and data transmission and reception.

[0037] The embedded software implements the interface with the host computer, FPGA chip and RF chip, receives the parameters of the host computer and configures the software and RF. It is also responsible for loading and parameter configuration of the FPGA software, receiving the status information of the FPGA chip and RF chip, uploading the status information required by the main control, and sending and receiving data between the host computer and FPGA.

[0038] The FPGA software mainly implements digital signal processing, receives control from embedded software, uploads status information, and sends and receives data from the ARM chip and RF chip.

[0039] The smart deployment module is separable from the SCA radio system. The smart deployment module is deployed in the terminal device: the terminal device can be a mobile terminal, a fixed terminal or a portable terminal; it can be integrated with the SCA radio or separated from the SCA radio, and the specific structure of the SCA radio is determined by the specific usage scenario.

[0040] The SCA radio system upgrade method provided in the embodiment of the present application specifically refers to an upgrade method for upgrading a traditional radio to an SCA radio, and the specific steps are as follows.

[0041] S1. The smart deployment module activates the universal driver when it is powered on and connected to the system.

[0042] The above universal driver is deployed in the smart deployment module. When the smart deployment module is powered on and connected to the system, the universal driver is automatically activated and starts working. That is, the universal driver is the first startup item of the smart deployment module.

[0043] S2. The universal driver sends a request to start the SCA system to the host computer master control software.

[0044] After the smart deployment module is powered on and connected to the system, the universal driver will send a request to start the SCA system to the host computer master control software through the LAN. Here, the method in which the universal driver sends the request to start the SCA system to the host computer master control software is not limited to the LAN.

[0045] S3. After the master control software responds with approval, the universal driver is loaded on the ARM chip and the dedicated driver is started.

[0046] After the main control software responds with yes, the original control and data transmission and reception will be stopped, and the universal driver will load and start the dedicated driver through remote login and ftp / tftp. The dedicated driver will take over the system hardware resources, and the original embedded software program will exit.

[0047] The dedicated driver starts the management system, the management system monitors the smart deployment module, the dedicated driver detects the heartbeat packet of the smart deployment module, the dedicated driver loads the soft-no operating environment from the smart deployment module, and loads the traditional operation flow into the SCA waveform file by mapping the process, and then starts the system management. At the same time, the management system monitors the smart deployment module, the dedicated driver detects the heartbeat packet of the smart deployment module, and determines the status of the smart deployment module based on whether it times out. If the smart deployment module exits the system or is unplugged and powered off, the system is restarted and restored to the traditional radio station. The radio station will load and work the waveform in the traditional way; if the heartbeat packet is in a normal state, the system manager uploads the radio station status to the upper computer master control, and receives the command of the upper computer master control at the same time, and completes the SCA waveform deployment, switching, waveform component data reception and transmission, parameter configuration, etc. in a soft-no way according to the command.

[0048] S4. The dedicated driver loads SCA operating system components, SCA waveforms and management system on the ARM chip; the SCA waveform covers the FPGA software.

[0049] The SCA operating system components, SCA waveforms and management system pre-stored in the soft deployment module will be reloaded onto the ARM chip through the network; the original FPGA software will be overwritten by the SCA waveform application; and the traditional radio station will be upgraded to an SCA radio station.

[0050] The embodiment of the present application provides that after a traditional radio station is upgraded to an SCA radio station, the management system loaded in the ARM chip starts to manage the SCA waveform, and the specific steps are as follows.

[0051] S1. The management system uploads its own status and accepts the control of the main control software.

[0052] The status of the management system itself specifically refers to whether the management system is started normally and whether it can communicate normally with the main control software.

[0053] S2. The management system deploys the SCA waveform.

[0054] The management system loaded in the ARM chip deploys the SCA waveform loaded in the ARM chip, and deploys it on the ARM chip and the FPGA chip respectively. The management system is responsible for managing the SCA waveform in the SCA radio station.

[0055] S3. The main control software controls the sending and receiving of SCA waveform data.

[0056] Taking FM waveform as an example, the audio file is sent to the waveform component through the main control software. The waveform component processes the audio data and finally uploads it to the main control software.

[0057] S4. The main control software switches the SCA waveform.

[0058] If the FM waveform completes the use of related functions, the main control software will switch to other SCA waveforms (AM and other waveforms) according to specific scenarios.

[0059] The present application embodiment provides two ways to switch from a traditional radio station to an SCA radio station, one is the active mode of the smart deployment module, and the other is the passive mode. Figure 5 and Figure 6 shown.

[0060] Active mode: The Smart Deployment Module is powered on and inserted into the system, and actively sends a switching request through the network. The host computer master receives the request and switches to the SCA radio operation if it agrees. If it disagrees, it waits until the host computer master actively sends a switching command or the Smart Deployment Module is powered off and unplugged.

[0061] Passive mode: The host computer master sends a switching command through the network, and the smart deployment module sends a confirmation switch to the host computer master and executes the switch to the SCA radio operation.

[0062] The embodiment of the present application provides two ways to restore from SCA radio to traditional radio, one is that the host computer master actively switches, and the other is that the smart deployment module is powered off (unplugged). Figure 7 and Figure 8 shown.

[0063] Active switching: The host computer master sends a switching command through the network. After the smart deployment module confirms the switching command, the master restarts the system and switches to the traditional radio mode.

[0064] Module power failure: Unplug the smart deployment module, the heartbeat packet of the smart deployment module stops, and the host computer master detects that the heartbeat stops and restarts the system, and the system switches to traditional radio mode.

[0065] The Soft-Free Smart Deployment Module integrates an operating environment that can run SCA and stores waveform applications based on SCA. When the access radio device is successfully started, the Soft-Free Smart Deployment Module will start the domain manager and device manager, establish the SCA domain, and use itself as a master node, while the traditional radio device is used as a slave node. The management system takes over the operation flow, control flow and data flow of the traditional radio, and converts them into the operation flow, control flow and data flow under SCA through the mapping process, so as to upgrade the traditional radio to the SCA-based Soft-Free Radio. When the SCA architecture is not needed, the Soft-Free Smart Access Module can be simply and quickly exited and restored to the traditional radio. The Soft-Free Smart Deployment Module can be used to upgrade the traditional radio to the Soft-Free Radio. The Soft-Free Radio adopts an architecture based on the Software Communication Architecture (SCA), and realizes hardware and software isolation through the middleware and core framework, so that waveforms from different waveform manufacturers can be deployed on the Soft-Free Radio. The Soft-Free Smart Deployment Module can simplify the upgrade and transformation process, greatly reduce the workload of the upgrade and transformation, and also ensure the reliability of the system and avoid the risks brought by the upgrade and transformation.

[0066] Although the above describes the illustrative specific embodiments of the present invention to facilitate those skilled in the art to understand the present invention, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations using the concept of the present invention are protected.
