Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] GSM (Global System for Mobile Communications) is a TDMA (Time Division Multiple Access) system. A TDMA frame consists of eight time slots, which are allocated to the UE and share a single radio resource. A radio resource, with a bandwidth of 200kHz, can be considered as one TRX (Transceiver Unit), representing one frequency band. The number of users a single TRX can support is limited; when the cell has more users, multiple TRXs are needed to expand capacity.

[0027] A TRX (Transceiver) is a device that simultaneously transmits and receives signals. In a GSM system, the TRX is one of the core components of a Base Station (BTS), responsible for transmitting and receiving wireless signals. A BTS typically contains multiple TRXs, each corresponding to a carrier frequency.

[0028] This application provides a synchronization method for a mobile communication system. An external clock is set via a time-preservation module, and synchronization information is sent to each communication module, achieving time and frequency domain synchronization of multiple communication modules. This ensures user experience while reducing expansion costs, solving the problem of how to reduce expansion costs in mobile communication. The mobile communication system includes a time-preservation module, multiple communication modules, and a base station signal transmission module, with the time-preservation module communicatively connected to each communication module. (See reference...) Figure 1 The synchronization method of the mobile communication system includes steps S101 to S109.

[0029] In step S101, in response to the power-on command information, the communication connection information is determined.

[0030] In one possible implementation, the power-on instruction information includes a first power-on instruction and a second power-on instruction, wherein the first power-on instruction represents non-delayed power-on, and the second power-on instruction represents delayed power-on. The step of determining communication connection information in response to the power-on command information includes: When the base station signal transmission module issues the first power-on command, the communication connection information is determined to be the first communication connection information; the first communication connection information indicates that a communication connection has been established at the current moment. When the base station signal transmission module issues the second power-on command, the communication connection information is determined to be the second communication connection information; the second communication connection information indicates that a communication connection is established at the target time corresponding to the second power-on command.

[0031] In one possible implementation, such as Figure 2 As shown, a typical GSM base station system includes an L1 subsystem and a BTS subsystem. The L1 subsystem is used to configure the USRP and perform some signal processing at the physical layer; the BTS subsystem's main functions include scheduling, power control, and UL / DL transmission channel data processing. Specifically, the communication module can be a USRP.

[0032] In one possible implementation, the USRP (Universal Software Radio Peripheral) is a software-defined radio hardware device. It includes an RF frontend, an FPGA, a host interface, and clock synchronization. The RF frontend is responsible for signal transmission and reception, and includes an ADC / DAC (analog-to-digital / digital-to-analog converter), mixer, filters, etc. Clock synchronization is used to support external reference clocks (such as GPSDO) for multi-device collaborative operation. The USRP supports wider frequency bands, full-duplex operation, and real-time processing.

[0033] In one possible implementation, such as Figure 3 As shown, the mobile communication system is a GSM 4TRX base station system, including a physical layer L1, used to configure the USRP and some signal processing of the physical layer. Specifically, the physical layer is the lowest layer of the communication protocol stack (L1 in the wireless protocol stack), directly responsible for bit stream transmission, converting data into electromagnetic signals and transmitting them through a medium (such as cable, optical fiber, or wireless channel), and supporting flexible time slot configuration.

[0034] In one possible implementation, such as Figure 3 As shown, the multiple communication modules can be two USRPs.

[0035] In one possible implementation, such as Figure 3As shown, the time synchronization module is communicatively connected to each USRP. The time synchronization module provides a high-precision external clock and a PPS (Pulse Per Second) pulse. The clock output is connected to the reference clock inputs of the two USRPs, and the PPS pulse output is connected to the PPS inputs of the two USRPs. Specifically, the PPS pulse is a high-precision time synchronization signal that outputs one pulse per second.

[0036] In one possible implementation, the plurality of communication modules may also be three USRPs (B210).

[0037] In one possible implementation, the power-on instruction information includes a first power-on instruction and a second power-on instruction. The first power-on instruction represents non-delayed power-on, that is, controlling the GSM 4TRX base station system to power on at the current time; the second power-on instruction represents delayed power-on, that is, controlling the GSM 4TRX base station system to power on at a preset future time. Specifically, the preset future time is the target time corresponding to the second power-on instruction.

[0038] In one possible implementation, when the base station signal transmission module issues the first power-on command, the communication connection information is determined to be the first communication connection information, that is, a communication connection between the BTS and L1 is established at the current moment.

[0039] In one possible implementation, when the base station signal transmission module issues the second power-on command, the communication connection information is determined to be the second communication connection information, that is, a communication connection between the BTS and L1 is established at the target time corresponding to the second power-on command.

[0040] In one possible implementation, under non-delayed power-on conditions, the power-on command format sent by BTS to L1 is POWERON, that is, the first power-on instruction is POWERON.

[0041] In one possible implementation, in the case of delayed boot, the second boot instruction carries a parameter T, where T is the Linux standard time. The format of the second boot instruction can be "POWERON T". Both the BTS and L1 system time are aligned with the Linux standard time. Specifically, T represents a future time.

[0042] In this implementation, communication connection information is determined based on different power-on command information to ensure that the communication connection time is consistent and improve the accuracy of synchronization.

[0043] In step S103, a communication connection between the base station signal transmission module and the physical layer is established based on the communication connection information.

[0044] In one possible implementation, establishing a communication connection between the base station signal transmission module and the physical layer based on the communication connection information includes: If the communication connection information is the first communication connection information, a communication connection is established between the base station signal transmission module and the physical layer at the current moment; When the communication connection information is the second communication connection information, a communication connection is established between the base station signal transmission module and the physical layer at the target time corresponding to the second power-on command.

[0045] In one possible implementation, the physical layer includes a first physical layer and a second physical layer. Establishing the communication connection between the base station signal transmission module and the physical layer includes: Establish a communication connection between the base station signal transmission module and the first physical layer; And establish a communication connection between the base station signal transmission module and the second physical layer.

[0046] In one possible implementation, such as Figure 4 As shown, when the communication connection information is the first communication connection information, a communication connection between BTS and L1 is established at the current time, i.e., the current time is time T.

[0047] In one possible implementation, such as Figure 4 As shown, the physical layer L1 includes a first physical layer L1-1 and a second physical layer L1-2, which establish communication connections between the BTS and L1-1 and L1-2 respectively.

[0048] In one possible implementation, such as Figure 4 As shown, when the communication connection information is the second communication connection information, at time T, communication connections are established between BTS and L1-1 and L1-2 respectively.

[0049] In one possible implementation, communication between L1 and BTS uses UDP transmission. Specifically, UDP (User Datagram Protocol) is characterized by connectionless operation, low latency, simplicity, and high efficiency, making it suitable for scenarios with high real-time requirements.

[0050] In this implementation, a communication connection between the base station signal transmission module and the physical layer is established based on different communication connection information, laying the foundation for achieving synchronization in the frequency domain and time domain.

[0051] In step S105, after the communication connection is established, synchronization information is obtained; the synchronization information is generated based on the time preservation module.

[0052] In one possible implementation, such as Figure 4 As shown, after L1-1 establishes a communication connection with BTS, BTS sends a power-on command to L1-1 at time T. After L1-2 establishes a communication connection with BTS, BTS also sends a power-on command to L1-2 at time T.

[0053] In one possible implementation, such as Figure 4 As shown, after the communication connection is established, synchronization information is obtained. The synchronization information includes clock information and pulse information, which are generated by the time preservation module.

[0054] In step S107, sampling information for each communication module is set based on the synchronization information.

[0055] In one possible implementation, the synchronization information includes clock information and pulse information. The step of setting the sampling information for each communication module based on the synchronization information includes: The clock information is input into the clock input interface of each communication module to obtain the sampling time of each communication module; And input the pulse information into the pulse input interface of each communication module to obtain the synchronization pulse information of each communication module; The sampling time and synchronization pulse information of each communication module are determined, and the sampling information for each communication module is recorded.

[0056] In one possible implementation, such as Figure 4 As shown, when time T arrives, L1-1 and L1-2 simultaneously set their respective GSM Time(0,0) and the same sampling time for their respective USRPs (B210), and the next PPS takes effect. Since the two USRPs (B210) are connected to the same PPS source, the sampling start time of the two USRPs (B210) will also be the same when the next PPS pulse arrives.

[0057] In one possible implementation, such as Figure 4 As shown, since the two USRPs use the same reference clock source, their sampling times are continuously synchronized. The GSM Time of the two L1 modules is data-driven based on their respective USRPs, so their subsequent GSM Time is also continuously synchronized.

[0058] In this implementation, each communication module provides sampling time and synchronization pulse information based on the same high-precision external clock, achieving alignment at the source of time. This approach uses multiple low-cost communication modules to achieve high capacity and reduces expansion costs.

[0059] In step S109, each communication module is controlled to transmit and receive signals based on the sampling information.

[0060] In one possible implementation, controlling the transmission and reception of signals by each communication module based on the sampling information includes: Based on the sampling time and synchronization pulse information of each communication module, the signal transmission and reception of each communication module are controlled.

[0061] In one possible implementation, after controlling the transmission and reception of signals by each communication module based on the sampling information, the method further includes: Obtain the internal clock signal of each communication module; The internal clock signal of each communication module is transmitted to the base station signal transmission module, so that the base station signal transmission module schedules frame data based on the internal clock signal of each communication module and the preset advance.

[0062] In one possible implementation, such as Figure 4 As shown, L1-1 and L1-2 periodically report GSM Time to BTS, and BTS schedules frame data based on this GSM Time plus an advance factor. By optimizing the allocation of resources such as time slots, frequencies, and power, network efficiency is improved and diverse service requirements are met.

[0063] In one possible implementation, the GSM 4TRX base station system can function normally for transmission and reception after the L1-1 and L1-2 subsystems are continuously synchronized with the BTS.

[0064] In this implementation, each communication module is controlled to send and receive signals based on the sampling information, thus meeting user needs while maintaining continuous synchronization between the physical layer and the base station.

[0065] The above embodiments of this application have the following beneficial effects: The mobile communication system of this application includes a time-preservation module, multiple communication modules, and a base station signal transmission module. The time-preservation module is communicatively connected to each communication module, and in response to a power-on command, determines communication connection information. Based on the communication connection information, a communication connection is established between the base station signal transmission module and the physical layer. After the communication connection is established, synchronization information is acquired. The synchronization information is generated based on the time-preservation module. Based on the synchronization information, sampling information for each communication module is set. Based on the sampling information, each communication module is controlled to transmit and receive signals. By setting an external clock through the time-preservation module and sending synchronization information to each communication module, synchronization of the time and frequency domains of multiple communication modules is achieved, ensuring user experience while reducing expansion costs, thus solving the problem of how to reduce expansion costs in mobile communication.
