Description

Technical Field

[0001] This invention belongs to the field of communication technology, and in particular relates to a communication method and related products. Background Technology

[0002] Fiber to the Room (FTTR) is a broadband access method based on fiber optic communication technology. An FTTR system provides high-speed internet access to electronic devices in each room by laying fiber optic cables directly from the optical line terminal unit (OLP) of a Passive Optical Network (PON) to each room requiring communication signals. An FTTR system typically includes an FTTR master gateway and multiple FTTR slave gateways. The master gateway connects to the slave gateways via fiber optic links to provide internet access to electronic devices within the room.

[0003] In related technologies, FTTR typically uses Wireless Fidelity (Wi-Fi) communication from the gateway. However, Wi-Fi communication has a narrow bandwidth, resulting in low communication rates, which cannot meet the demanding data transmission performance requirements of applications such as ultra-high-definition video streaming, virtual reality, augmented reality, and online gaming. Therefore, improving the communication rate of FTTR systems is a topic of concern. Summary of the Invention

However, they do not mean that the applicant has used or necessarily used the solution.

[0057] To address the problems in related technologies, embodiments of the present invention provide a communication method and related products, which may include communication devices, fiber-to-the-room (FTTR) systems, master gateways, slave gateways, computer-readable storage media, and computer program products.

[0058] First, combined Figure 1 The fiber-to-room (FTTR) system provided in the embodiments of this application will be described in detail.

[0059] In some embodiments of this application, such as Figure 1 As shown, the Fiber to the Room (FTTR) system 10 may include a master gateway 101 and at least one slave gateway 102.

[0060] The main gateway 101 is used to process the PON downlink optical signal to obtain a modulated optical signal when the FTTR system 10 receives the PON downlink optical signal. The slave gateway 102 is used to determine the millimeter-wave electrical signal based on the modulated optical signal and the reference optical signal output by the main gateway 101, and to send the millimeter-wave electrical signal to the electronic devices accessing the slave gateway 102.

[0061] Electronic devices can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, and other devices with communication functions.

[0062] Therefore, by processing the PON downlink optical signal through the main gateway, the original optical signal from the PON network can be converted into a modulated optical signal more suitable for transmission within the FTTR system and processing by the slave gateway. This improves signal quality and transmission accuracy, providing a good signal foundation for subsequent processing by the slave gateway and the access of electronic devices. Subsequently, the slave gateway, through processing the modulated optical signal and the reference optical signal, can accurately extract the millimeter-wave electrical signal and send it to the accessed electronic devices. This enables electronic devices in the room to obtain high-speed, stable network connections, meeting users' needs for high-speed data transmission, improving the user's network experience, and effectively solving the problem of low communication speed in the FTTR system.

[0063] The main gateway and the secondary gateway are explained below.

[0064] In some embodiments of this application, the main gateway includes a signal processing module, which includes signal processing components and optical signal modulation components.

[0065] The signal processing component is used to determine the reference electrical signal based on the PON downlink optical signal; the optical signal modulation component is used to modulate the reference electrical signal to obtain the modulated optical signal.

[0066] In some embodiments of this application, the signal processing component includes a photoelectric conversion sub-component and an electrical signal processing sub-component.

[0067] The photoelectric conversion sub-component is used to perform signal conversion processing on the PON downlink optical signal to obtain a downlink electrical signal; the electrical signal processing sub-component is used to perform demodulation processing on the downlink electrical signal to obtain a baseband electrical signal, and to perform modulation processing on the baseband electrical signal to obtain a reference electrical signal.

[0068] In some embodiments of this application, the main gateway includes an optical transmitting module; wherein the optical transmitting module is used to transmit a reference optical signal to the slave gateway before determining the millimeter-wave electrical signal based on the modulated optical signal and the reference optical signal output by the main gateway through the slave gateway; the optical signal modulation component is also used to transmit the modulated optical signal to the slave gateway.

[0069] In some embodiments of this application, the gateway includes a photoelectric conversion module, which includes an optical signal processing component and a photoelectric conversion component.

[0070] The optical signal processing component is used to process the modulated optical signal and the reference optical signal to obtain an optical heterodyne signal, wherein the optical heterodyne signal is a mixed signal of the modulated optical signal and the reference optical signal on the reference photosensitive surface; the photoelectric conversion component is used to perform signal conversion processing on the optical heterodyne signal to obtain a millimeter-wave electrical signal.

[0071] In some embodiments of this application, the gateway includes an electrical signal preprocessing module.

[0072] Among them, the electrical signal preprocessing module is used to preprocess the millimeter-wave electrical signal before sending it to the electronic device connected to the gateway, so as to obtain the processed millimeter-wave electrical signal.

[0073] This application also provides a main gateway, which includes a signal processing module and an optical transmission module.

[0074] The signal processing module is used to process the PON downlink optical signal received by the fiber-to-the-room (FTTR) system through the main gateway to obtain a modulated optical signal, and then transmit the modulated optical signal to the slave gateway. The optical transmission module is used to transmit a reference optical signal to the slave gateway.

[0075] Therefore, the PON downlink optical signal is converted into a modulated optical signal after processing by the signal processing module, enhancing the stability of signal transmission within the FTTR system. The reference optical signal emitted by the optical transmitting module provides a reference for the gateway to process the modulated optical signal.

[0076] This application also provides a slave gateway, which includes an optical receiving component for receiving a modulated optical signal and a reference optical signal output by a master gateway, respectively.

[0077] Therefore, by setting up an optical receiving component, the slave gateway can accurately and timely receive the modulated optical signal and reference optical signal emitted by the master gateway.

[0078] Secondly, based on the aforementioned FTTR system, combined with the attached Figure 2 To be continued Figure 6 The communication method provided in this application will be described in detail through specific embodiments and application scenarios.

[0079] Figure 2 A flowchart illustrating a communication method provided by some embodiments of the present invention is shown.

[0080] like Figure 2 As shown, this communication method can be applied to, for example... Figure 1 The FTTR system, the communication method may include steps 210 to 230.

[0081] Step 210: Upon receiving a PON downlink optical signal, the PON downlink optical signal is processed through the main gateway to obtain a modulated optical signal.

[0082] Step 220: Determine the millimeter-wave electrical signal from the gateway based on the modulated optical signal and reference optical signal output from the main gateway;

[0083] Step 230: Send millimeter-wave electrical signals to electronic devices connected to the gateway.

[0084] Therefore, by processing the PON downlink optical signal through the main gateway, the original optical signal from the PON network can be converted into a modulated optical signal more suitable for transmission within the FTTR system and processing by the slave gateway, thus improving signal quality and transmission accuracy. In this way, the slave gateway, through processing the modulated and reference optical signals, can accurately extract the millimeter-wave electrical signal and send it to the accessed electronic devices. This enables electronic devices in the room to obtain high-speed, stable network connections, effectively improving the communication rate of the FTTR system. It also addresses the current limitations of narrow bandwidth and low communication speed in Wi-Fi communication, meeting the stringent data transmission performance requirements of applications such as ultra-high-definition video streaming, virtual reality, augmented reality, and online gaming.

[0085] The steps described above are explained in detail below.

[0086] First, regarding step 210, in some embodiments of this application, the PON downlink optical signal is a response signal corresponding to the PON uplink optical signal sent by the FTTR system to the PON, and the PON uplink optical signal corresponds to a user request sent by an electronic device accessing the gateway. Exemplarily, the PON network downlink signal reaches the FTTR master gateway via the drop fiber.

[0087] PON technology is a point-to-multipoint fiber optic access technology, which consists of an optical line terminal (OLT) at the central office, an optical network unit (ONU) at the user side, and an optical distribution network (ODN) for splitting and transmission.

[0088] In an FTTR system, the PON downlink optical signal originates from the OLT at the central office, travels along the ODN to the ONU on the user side, and finally connects to the user's electronic equipment. The PON downlink optical signal is a response signal generated by the PON network in response to the PON uplink optical signal sent by the FTTR system. It contains feedback data from user requests, such as website page data or video stream data, thus ensuring bidirectional data interaction and transmission between the FTTR system and the PON network. Correspondingly, the FTTR system can send PON uplink optical signals to the PON network. These PON uplink optical signals correspond to user requests sent by electronic equipment accessing the gateway. The content of the PON uplink optical signal can include instructions to access a target website, online video playback requests, etc.

[0089] In order to process PON downlink optical signals and transmit modulated optical signals to slave gateways, in some embodiments of this application, the main gateway includes a signal processing module, which includes signal processing components and optical signal modulation components. Based on this, as Figure 3 As shown, step 210 above may specifically include steps 2101 to 2102.

[0090] Step 2101: Determine the reference electrical signal based on the PON downlink optical signal using the signal processing component.

[0091] For example, the signal processing component receives the PON downlink optical signal and converts the PON downlink optical signal into a reference electrical signal.

[0092] Step 2102: Modulate the reference electrical signal using an optical signal modulation component to obtain a modulated optical signal.

[0093] The optical signal modulation component includes a reference laser and an optical transmitter.

[0094] For example, a reference electrical signal is input into the optical signal modulation component. The reference electrical signal is amplified by the amplifier circuit built into the driver chip of the reference laser to compensate for the loss of the reference electrical signal during transmission and enhance the strength of the reference electrical signal. The amplified reference electrical signal is then applied to the reference laser. By changing the operating parameters of the reference laser, the information carried by the reference electrical signal is loaded onto the optical carrier emitted by the reference laser. Subsequently, the power of the modulated optical signal is adjusted to obtain a modulated optical signal that meets the transmission requirements of the FTTR system.

[0095] Thus, through the modulation process, the reference electrical signal is effectively loaded onto the optical carrier, and the generated modulated optical signal can be stably transmitted within the FTTR system, which helps the gateway to accurately process the signal.

[0096] In some embodiments of this application, the signal processing component includes a photoelectric conversion sub-component and an electrical signal processing sub-component. Based on this, as... Figure 4 As shown, step 2101 above may specifically include steps 21011 to 21013.

[0097] Step 21011: The PON downlink optical signal is converted into a downlink electrical signal by the photoelectric conversion sub-component.

[0098] The photoelectric conversion sub-component is used to convert optical signals into electrical signals. In this embodiment, the photoelectric conversion sub-component can be a photodetector. The photodetector utilizes the principle of the photoelectric effect to convert the energy of the received optical signal into electrical energy, thereby realizing the conversion of PON downlink optical signals into downlink electrical signals.

[0099] Step 21012: The downlink electrical signal is demodulated by the electrical signal processing sub-component to obtain the baseband electrical signal.

[0100] The electrical signal processing sub-component is used to perform various processing operations on electrical signals, such as demodulation, modulation, and filtering, in order to achieve signal recovery, conversion, and adaptation.

[0101] For example, the electrical signal processing subcomponent receives the downlink electrical signal output by the photoelectric conversion subcomponent, demodulates the downlink electrical signal to restore the original signal modulated on the carrier wave, and obtains the baseband electrical signal carrying the original information.

[0102] In the application scenarios of this application embodiment, the original information carried by the baseband electrical signal includes service resource information corresponding to the user request, such as the web page content and video data requested by the user.

[0103] Step 21013: Modulate the baseband electrical signal using the electrical signal processing sub-component to obtain a reference electrical signal.

[0104] Modulation is the process of loading baseband electrical signals onto a carrier wave so that the signals can be transmitted more effectively in a specific channel.

[0105] For example, the electrical signal processing subcomponent first performs FTTR network routing. Specifically, the electrical signal processing subcomponent considers the status information of each node in the network, such as signal strength, bandwidth usage, and node load. Then, it selects an optimal transmission path based on preset routing algorithms such as shortest path algorithms and load balancing algorithms. Next, it performs radio frequency baseband modulation on the baseband electrical signal. According to the requirements of the air interface transmission protocol, it selects an appropriate modulation method and loads the baseband electrical signal onto the carrier. Finally, a reference electrical signal that satisfies the air interface transmission protocol is obtained.

[0106] Therefore, since electrical signals are easier to amplify, filter, and demodulate, the PON downlink optical signal is converted into a downlink electrical signal by the photoelectric conversion sub-component, enabling the electrical signal processing sub-component to further process the signal. Next, the electrical signal processing sub-component demodulates the downlink electrical signal to obtain service resource information corresponding to the user's request. Subsequently, the baseband electrical signal is modulated and routed to obtain a reference electrical signal that meets the air interface transmission protocol, allowing for more efficient and stable transmission in the FTTR network. Thus, through photoelectric conversion, demodulation, routing, and modulation, the PON downlink optical signal can be converted into a reference electrical signal that meets the FTTR network air interface transmission protocol, thereby ensuring efficient data transmission in the FTTR system.

[0107] In some embodiments of this application, the main gateway includes an optical transmitting module; based on this, before step 220 above, the communication method may further include: transmitting a modulated optical signal to the slave gateway through the optical signal modulation component of the main gateway; and transmitting a reference optical signal to the slave gateway through the optical transmitting module.

[0108] In the embodiments of this application, the optical emission module is a component with a reference laser as the core light source, used to generate and emit a stable, single-frequency reference optical signal.

[0109] For example, when the master gateway receives the PON downlink optical signal and begins to process the modulated optical signal, the reference laser in the optical transmitting module starts working to generate a stable laser, i.e., a reference optical signal. After the master gateway receives the PON downlink optical signal and processes the modulated optical signal, it will simultaneously transmit the modulated optical signal and the reference optical signal to the slave gateway. The slave gateway uses the reference optical signal as a reference to accurately parse and process the modulated optical signal, thereby improving the accuracy and reliability of signal processing and thus enhancing the communication quality of the entire FTTR system.

[0110] In some embodiments of this application, the gateway includes a photoelectric conversion module, which includes an optical signal processing component and a photoelectric conversion component. Based on this, such as Figure 5 As shown, step 220 above may specifically include steps 2201 and 2202.

[0111] Step 2201: The modulated optical signal and the reference optical signal are processed by the optical signal processing component to obtain the optical heterodyne signal, wherein the optical heterodyne signal is the mixing signal of the modulated optical signal and the reference optical signal on the reference photosensitive surface.

[0112] The optical signal processing component includes an optical coupler, which combines the modulated optical signal and the reference optical signal into the same optical path, causing them to spatially overlap. The overlapped modulated and reference optical signals are then guided to the reference photosensitive surface of the photodetector. Because the modulated and reference optical signals have different frequencies, coherent mixing occurs when they meet on the photosensitive surface, resulting in an optical heterodyne signal.

[0113] Step 2202: The optical heterodyne signal is converted and processed by a photoelectric conversion component to obtain a millimeter-wave electrical signal.

[0114] The photoelectric conversion component includes a photodetector, which converts the energy of the optical heterodyne signal into a millimeter-wave electrical signal. Millimeter-wave electrical signals, with frequencies in the millimeter-wave band (e.g., 30GHz-300GHz), have the characteristics of large bandwidth and high transmission rate, making them suitable for high-speed data transmission.

[0115] Therefore, by processing the modulated optical signal and the reference optical signal using optical signal processing components, an optical heterodyne signal is obtained. This effectively extracts signals of specific frequencies, converting high-frequency optical signals into relatively low-frequency and easily processed optical heterodyne signals. Then, a photodetector successfully converts the optical heterodyne signal into a millimeter-wave electrical signal. Because millimeter-wave electrical signals have high-speed transmission characteristics, they can meet users' needs for high-speed data transmission. Thus, the gateway converts the received optical signal into a millimeter-wave electrical signal suitable for communication with electronic devices, providing high-speed and stable network connections for electronic devices connected to the gateway, thereby improving the communication performance of the FTTR system.

[0116] In some embodiments of this application, the gateway includes an electrical signal preprocessing module; based on this, before step 230 above, the communication method may further include performing signal preprocessing on the millimeter-wave electrical signal through the electrical signal preprocessing module to obtain the processed millimeter-wave electrical signal.

[0117] The electrical signal preprocessing module is used to amplify, filter, and digitize the millimeter-wave electrical signal output by the photoelectric conversion component to obtain the processed millimeter-wave electrical signal.

[0118] For example, the electrical signal preprocessing module may include an amplifier, a filter, and an analog-to-digital converter (ADC). The millimeter-wave electrical signal output from the photoelectric conversion component first enters the amplifier, which amplifies the amplitude of the input millimeter-wave electrical signal according to a preset amplification factor. Next, the amplified signal is input to the filter to remove low-frequency noise and high-frequency interference. Subsequently, the filter inputs the filtered analog signal to the ADC. The ADC samples the analog signal and quantizes the sampled values ​​into digital codes, thereby converting the analog signal into a digital signal. In this way, the millimeter-wave electrical signal completes its preprocessing, resulting in a processed millimeter-wave electrical signal.

[0119] Based on this, the gateway also includes an electrical signal transmission module, which can be a radio frequency antenna. The radio frequency antenna is a device for converting electrical signals into electromagnetic waves and radiating them into space, capable of transmitting and receiving signals in the millimeter-wave band. Specifically, step 230 may include sending processed millimeter-wave electrical signals to electronic devices connected to the gateway.

[0120] For example, the processed millimeter-wave electrical signal is transmitted to the radio frequency antenna in the electrical signal transmission module. The radio frequency antenna converts the electrical signal into electromagnetic waves in the millimeter-wave band and transmits the millimeter-wave electromagnetic waves directionally or omnidirectionally, so that electronic devices connected to the gateway can receive the signal.

[0121] Therefore, by processing the electrical signal through the preprocessing module, the quality and strength of the millimeter-wave electrical signal can be improved, enabling accurate transmission of the processed signal to electronic devices. Due to the large bandwidth and high transmission rate of the millimeter-wave band, the processed signal can provide high-speed and stable network connections for electronic devices. In this way, electronic devices can efficiently receive data, meeting the demands of applications with stringent data transmission performance requirements, such as ultra-high-definition video streaming and virtual reality.

[0122] The communication method provided in this application can be executed by a communication device. Based on this, this application also provides a communication device, specifically combined with… Figure 6 Please provide a detailed explanation.

[0123] like Figure 6 As shown, this communication device can be applied to a fiber-to-the-room (FTTR) system, which includes a master gateway and a slave gateway. The communication device 600 may include:

[0124] The processing module 610 is used to process the PON downlink optical signal through the main gateway to obtain a modulated optical signal when the PON downlink optical signal is received.

[0125] The determination module 620 is used to determine the millimeter-wave electrical signal from the gateway based on the modulated optical signal and the reference optical signal output from the main gateway;

[0126] The transmitting module 630 is used to transmit millimeter-wave electrical signals to electronic devices connected to the gateway.

[0127] Therefore, by processing the PON downlink optical signal through the main gateway, the original optical signal from the PON network can be converted into a modulated optical signal more suitable for transmission within the FTTR system and processing by the slave gateway, thus improving signal quality and transmission accuracy. In this way, the slave gateway, through processing the modulated and reference optical signals, can accurately extract the millimeter-wave electrical signal and send it to the accessed electronic devices. This enables electronic devices in the room to obtain high-speed, stable network connections, effectively improving the communication rate of the FTTR system. It also addresses the current limitations of narrow bandwidth and low communication speed in Wi-Fi communication, meeting the stringent data transmission performance requirements of applications such as ultra-high-definition video streaming, virtual reality, augmented reality, and online gaming.
