[0033] Embodiment 1

[0034] Figure 1 A flowchart of a cell construction method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of cell construction. The method is applied to a board chip. The board chip includes a message forwarding core, a time synchronization core and eight service cores. The method can be executed by a cell construction device. The cell construction device can be implemented in the form of hardware and / or software. The cell construction device can be configured in an integrated base station.

[0035] In this embodiment, the board chip can be understood as an enhanced core baseband processing SoC chip independently developed for 4G / 5G mobile communication systems. It adopts advanced and mature process technology. The core breaks through the shackles of traditional chip architecture. Through architectural innovation, it has high-density computing power and eight built-in business cores. The 4GHz MaPU board chip is responsible for 4G / 5G base station digital baseband processing; the 8GHz NPU board chip is responsible for 4G / 5G base station high-level protocol processing. A single chip can complete the processing of all functions of the 4G / 5G base station.

[0036] In this embodiment, the message forwarding kernel can be understood as a kernel that integrates multiple communication protocols for message forwarding, for example, it can integrate eCPRI, CPRI and SRIO at the same time, wherein eCPRI is a fronthaul interface protocol, which is intended to connect the baseband unit (BBU) or digital unit (DU) of the wireless base station and the active antenna unit (AAU); CPRI is a standardized interface protocol, which is intended to achieve efficient data exchange between the wireless equipment control center (REC) and the wireless equipment (RE) inside the wireless base station, and SRIO is a protocol for high-speed serial communication, which is intended to connect digital signal board chips (DSP), network board chips, FPGA and other chips, and the interconnection between them. The time synchronization kernel can be understood as a kernel that integrates multiple time synchronization function modules, for example, it can include PCLe module and TMAC module, wherein PCLe is the abbreviation of PCI Express, which is a high-speed serial bus standard for connecting external devices in computer systems, and TMAC module is a module for time management in communication systems.

[0037] like Figure 1 As shown, the method includes:

[0038] S110 , after power-on, initializing each service core, message forwarding core, time synchronization core, physical layer and media access controller based on the pre-configured version file.

[0039] In this embodiment, the pre-configured version file can be understood as a configuration file under the current version for cell configuration. The service kernel can be understood as a kernel for implementing cell services, which may include a main kernel, and the main kernel may be configured with a femtocell application programming interface (Femtocell Application Programming Interface, FAPI). The interface between the MAC layer and the PHY layer is defined through FAPI, which is used to configure the PHY layer in the small cell scenario and exchange data between the MAC layer and the PHY layer, and specifies a series of control messages and data transmission formats and timing, etc. During the cell establishment process, through FAPI, the MAC layer can send configuration information to the PHY layer, such as transmission mode, modulation and coding mode, frequency band selection, etc., so that the PHY layer can be initialized and configured according to the requirements of the MAC layer. At the same time, the PHY layer can also feedback link status, signal quality, synchronization information, etc. to the MAC layer through FAPI, so that the MAC layer can perform operations such as resource allocation, scheduling and link adaptation, and ensure the efficiency and reliability of data transmission during cell establishment and operation.

[0040] Specifically, first, the PC used for configuration can be connected to the board chip through the network port. After the board chip is powered on, the pre-configured version file is uploaded to the specified path, and the board chip is restarted. After restarting, the board chip can read the pre-configured version file through the specified path and initialize each business core, message forwarding core, time synchronization core, physical layer and media access controller.

[0041] S120. Send a request message to the physical layer through the media access controller.

[0042] In this embodiment, the request message may be understood as a message used to respond through the physical layer, and may include, for example, a parameter request (param request), a configuration request (config request), a cell establishment request (startrequest), and a cell deletion request (stop request).

[0043] Specifically, when there is a demand, a request message can be sent to a physical layer (PHY) through a media access controller (MAC), and the queue is forwarded to a message forwarding core for processing.

[0044] S130. Feedback the current status to the media access controller based on the request message through the physical layer.

[0045] In this embodiment, the current state may be understood as a state used to characterize whether the physical layer can be configured, for example, it may include a sleep state (idle state), a running state (running state) and a configured state (configured).

[0046] Specifically, when the physical layer receives the request message, it determines the operation that the media access controller needs to perform based on the different types of the request message, and thereby feeds back the current status to the media access controller based on the different request types.

[0047] S140. When the current state and the request message meet preset conditions, the service kernel is divided into service kernel groups according to the pre-configured version file, and cell-related parameters are configured for each service kernel group to provide cells under different mobile communication technologies through different service kernel groups.

[0048] The preset condition is that the request message received in the current state is a configuration completion state or a running state is a configuration request message.

[0049] In this embodiment, the preset condition can be understood as a condition for determining whether the physical layer can respond to the configuration request. The service core group can be understood as a group containing multiple service cores to implement a cell construction. Mobile communication technology can be understood as a technology that realizes communication between mobile devices through wireless technology, such as 4G mobile communication technology or 5G mobile communication technology.

[0050] Specifically, the physical layer can first divide the service core into service core groups through the pre-configuration version file according to the type corresponding to the current state and the request message when the current state and the request message meet the preset conditions, check whether the parameters configured in the pre-configuration version file are reasonable, and whether each parameter can be configured in the current state, calculate the corresponding cell-related parameters under the current configuration, and configure the cell-related parameters for each service core group to provide cells under different mobile communication technologies through different service core groups. For example, four service cores are divided into one service core group, so that two service core groups are included in the board chip. After the cell-related parameter configuration, one service core group can realize a 4G mobile communication cell, and the other service core group can realize a 5G mobile communication cell. Grouping can be performed according to actual needs.

[0051] S150: Feedback configuration information to the media access controller.

[0052] In this embodiment, the configuration information may be understood as information for characterizing the cell parameter configuration of the service core group.

[0053] Specifically, after the physical layer configures the cell-related parameters for the service core group, the configuration information may be fed back to the media access controller through the physical layer to notify the media access controller that the configuration is completed.

[0054] S160. The media access controller performs scheduling according to the configuration information to complete the establishment of the cell.

[0055] Specifically, the physical layer sends a message notification in each time slot, and the media access controller starts to perform scheduling after receiving the message notification.

[0056] The technical solution of the embodiment of the present invention is applied to a card chip, the card chip includes a message forwarding kernel, a time synchronization kernel and eight service kernels, and the method includes: after power-on, initializing each service kernel, message forwarding kernel, time synchronization kernel, physical layer and media access controller based on a pre-configured version file; sending a request message to the physical layer through the media access controller; feeding back the current state to the media access controller through the physical layer based on the request message; when the current state and the request message meet the preset conditions, dividing the service kernel into service kernel groups according to the pre-configured version file, and configuring the cell-related parameters for each service kernel group, so as to provide cells under different mobile communication technologies through different service kernel groups; feeding back the configuration information to the media access controller; and executing the scheduling according to the configuration information through the media access controller to complete the establishment of the cell. By deploying all the physical layer protocol stacks on the card chip, the establishment of different cells is realized at the same time, with low power consumption and small size.

[0057] Further, based on the above embodiment, the board chip further includes a double data rate synchronous dynamic random access memory DDR, and accordingly, each service core, message forwarding core, time synchronization core, physical layer and media access controller are initialized based on the pre-configured version file, including:

[0058] Based on the pre-configured version file, the memory of the high-speed storage array of the physical layer and the memory of the double data rate synchronous dynamic random access memory (DDRSDRAM) are initialized, and the message transmission module of the physical layer is initialized; the logging function of the message forwarding core, the platform management function initialization and the physical layer event message queue are initialized; the timing module, the memory management module initialization and the cell context are initialized; the clock delay information, logging function, platform management function, physical layer event message queue and background tasks of each business core are initialized.

[0059] In this embodiment, the high-speed storage array can be understood as a high-performance, high-reliability centralized data storage system, which provides unified data storage services by combining multiple storage devices (such as hard disks, SSDs, etc.) into a whole. Double data rate synchronous dynamic random access memory is a memory with a double data transfer rate, and its data transfer speed is twice the system clock frequency. The message transmission module (msg tarnsfer module) can be understood as a module for transmitting messages between different systems. The log function (log function) can be understood as a function for recording important logs such as various events and information during the operation of the kernel. The platform management function (shell function) can be understood as a command line interface used in the operating system to interact with users, execute commands and manage system resources. The event message queue can be understood as a queue where events and messages are stored. The timing module can be understood as a functional module related to time synchronization, etc., for example, which can include data handling, synchronous communication and queue processing functions. The memory management module can be understood as. The cell context can be understood as a series of information and parameters related to the user equipment (UE) in a mobile communication system. The clock delay information (tod information) can be understood as the real-time status information of the frequency hopping pattern or the real-time clock information, which is used to ensure the communication continuity and service quality of the user equipment during the mobile process. The memory management module can be implemented by a direct memory access (DMA) controller, which can be understood as allowing external devices to exchange data directly with the system's memory without the intervention of the board chip.

[0060] Specifically, based on the pre-configured version file, the board chip can initialize the memory of the high-speed storage array of the physical layer and the memory of the double data rate synchronous dynamic random access memory DDR, initialize the message transmission module (msgtarnsfer module) of the physical layer; initialize the log function of the message forwarding kernel, the platform management shell function initialization and the physical layer event message queue; initialize the timing module, the memory management module DMA initialization and the cell context; initialize the clock delay tod information, log function, platform management shell function, physical layer event message queue and background tasks of each business core.

[0061] Further, based on the above embodiment, the step of feeding back the current state to the media access controller based on the request message can be refined as follows:

[0062] When the request message is a cell establishment request, if the current state is in a dormant state or a configuration completion state, the current state is determined to be a correct state; otherwise, the current state is determined to be an error state; and the current state is fed back to the media access controller.

[0063] In this embodiment, the cell establishment request param request may be understood as a request for establishing a cell.

[0064] Specifically, when the request message is a cell establishment request, if the physical layer is currently in a sleep state or a configuration completion state, the current state is determined to be a correct state, and information such as the current physical layer configuration or physical layer capabilities is fed back; otherwise, the current state is determined to be an error state; and the current state is fed back to the media access controller.

[0065] Further, based on the above embodiment, the steps of dividing the service kernel into service kernel groups according to the pre-configured version file, and configuring cell-related parameters for each service kernel group, so as to provide cells under different mobile communication technologies through different service kernel groups, can be refined as follows:

[0066] If the initial configuration parameters in the pre-configuration version file are reasonable and each initial configuration parameter is configurable in the current state, the time slot parameter information is calculated based on the duplex mode and subcarrier spacing in the pre-configuration version file; the cell-related parameters are determined based on the initial configuration parameters and the time slot parameter information; based on the initial configuration parameters, the service core is divided into service core groups; cell-related parameters are configured for each service core group through cell-related parameters, so as to provide cells under different mobile communication technologies through different service core groups.

[0067] In this embodiment, the initial configuration parameters can be understood as the initial physical layer configuration parameters. The duplex mode can be understood as the way data is sent and received in the communication system, for example, it can include half-duplex mode, full-duplex mode, frequency division duplex mode and time division duplex mode. The subcarrier spacing can be understood as the frequency interval between two adjacent subcarriers. The slot parameter information can be understood as the basic unit for describing the allocation of time resources, for example, it can include the length and number of time slots. The cell-related parameters can be understood as the parameters used to build the cell, for example, they can include SSB parameters (which are important signal blocks for cell search and initial access in the 5GNR system. It not only provides the necessary synchronization information, but also transmits key system information through PBCH, so that the UE can successfully access the network and perform subsequent operations), RB number (referring to the number of basic units used to allocate wireless resources in the LTE system) and the conversion of phase compensation factors, etc.

[0068] Specifically, if the initial configuration parameters in the pre-configured version file are reasonable and each initial configuration parameter is configurable in the current state, the physical layer can first calculate the cell parameters, calculate the time slot length and number according to the duplex mode and subcarrier spacing to obtain the time slot parameter information, calculate the SSB parameters, RB number, and convert the phase compensation factor to obtain the cell-related parameters. The physical layer can divide different service cores into different service core groups based on the initial configuration parameters. Cell-related parameters are configured for each service core group through cell-related parameters to provide cells under different mobile communication technologies through different service core groups.

[0069] Among them, the steps of configuring the cell-related parameters for each service core group through the cell-related parameters can be refined as follows:

[0070] Obtain the task deployment configuration table in the preconfigured version file, configure the data movement module and timing module for the idle service core group, and allocate high-speed storage array resources and DDR resources; send inter-core messages to each service core in each service core group, and the inter-core messages include cell-related parameters and registration information; transfer the allocated resources to the physical layer management tasks of each service core.

[0071] In this embodiment, the task deployment configuration table can be understood as a detailed document used in the communication field to plan and manage various tasks in the process of cell construction, which is used to guide various tasks in the process of cell construction and help to reasonably allocate resources. The data movement module JESD (JEDEC Serial Data, JESD) csu can be understood as a communication industry standard, a module used to describe the exchange of high-speed digital data. The timing module jesd timer can be understood as a timer module based on the communication industry standard, which is used to perform time-related tasks. Registration information can be understood as a series of key data and configuration parameters exchanged when a connection is established between a mobile terminal and a network. The physical layer management task phy task can be understood as processing data transmission issues at the physical level.

[0072] Specifically, the physical layer can obtain the task deployment configuration table from the pre-configured version file, configure the data movement module and timing module for the service core group in the idle state, and allocate high-speed storage array resources and DDR resources; send inter-core messages to each service core in each service core group, and the inter-core messages include cell-related parameters and registration information; transmit the allocated resources to the physical layer management tasks of each service core.

[0073] Furthermore, the board chipset can be built into an integrated base station, which is mounted on a mobile device (such as a drone or vehicle, etc.), connected to the battery of the mobile device through a 12V wire, powered by the battery of the mobile device, and multiple mobile devices are deployed to designated locations for networking to form a mobile device group, establish temporary large-area mobile communication network coverage, and connect to the operator's core network through the integrated base station carried by the mobile device to provide communication services to users.
