Description

Technical Field

[0001] This application relates to the field of communication technologies, and more particularly, to an optical fiber network system and a method for up and down transmission of communication signals. Background Art

[0002] In the current era of mobile Internet, the wide application of 4G and 5G network technologies has become an important bridge connecting society and individuals, greatly enriching people's production and living styles. Behind this technological progress is the deployment of a large number of mobile communication base stations, which constitute a communication network covering the whole country and even the world. However, the construction cost of base stations is high and restricted by the outdoor environment, resulting in the network coverage mainly focusing on the large-area radiation of outdoor spaces to achieve wide signal coverage. For indoor environments such as residential communities and office buildings, building structures and wall materials will significantly weaken the propagation ability of wireless signals, forming coverage blind spots in the mobile communication network. When the signal strength drops below the minimum working threshold of the receiving device (such as a mobile phone), the communication connection will be interrupted or become unstable, seriously affecting the user experience, especially when making voice calls, sending and receiving text messages, and various data services.

[0003] In related technologies, most of the solutions proposed to solve indoor coverage blind spots rely on enhancing the signal transmission of outdoor base stations or adding outdoor base stations. This method has significant drawbacks. First, the cost issue: The construction of outdoor base stations requires complex property coordination, line laying, and equipment installation processes, which not only take a long time but also cost a lot. Second, resource waste: The signal coverage area of outdoor base stations is much larger than the actual indoor demand, easily leading to resource surplus and possibly causing signal interference problems. Third, lack of pertinence: Due to the differences in indoor environments of different buildings, such as structures, layouts, and materials, the distribution of wireless signal blind spots varies, and outdoor base stations cannot accurately meet the coverage requirements of specific indoor areas. In addition, when wireless signal coverage is required in a large area, such as in villas, large shopping malls, enterprise offices, etc., which require wide-area indoor coverage, a single device is difficult to achieve comprehensive signal coverage.

[0004] In view of the above problems, no effective solution has been proposed yet. Summary of the Invention

[0032] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily need to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] First, some nouns or terms that appear during the explanation of the embodiments of the present application are applicable to the following explanations:

[0035] PON (Passive Optical Network): An optical fiber communication network architecture mainly applied to broadband access networks to achieve point-to-multipoint optical fiber transmission. It consists of a central office device, a customer premise equipment, and a passive optical splitter. The PON network does not require intermediate active electronic devices, reducing network maintenance and power consumption, and is the cornerstone of application scenarios such as fiber to the home and fiber to the office.

[0036] OLT (Optical Line Terminal): A central office device in a PON network, located in the telecommunications operator's machine room or node. It is responsible for converting electrical signals from the switch into optical signals and sending the optical signals to each user-side device through optical fibers. The OLT also has the function of controlling and managing the entire PON network, and can perform device authentication, signal monitoring, fault diagnosis, etc.

[0037] ONU (Optical Network Unit): A user-side device in a PON network, usually deployed in the user's home or office. It is responsible for converting the received optical signal into an electrical signal and providing the user with network services for accessing the Internet. The ONU device may integrate multiple functions such as a router, a switch, and a Wi-Fi access point.

[0038] FTTR (Fiber To The Room): A new broadband access technology that directly lays optical fibers into each room of a residence, replacing the traditional copper wire or coaxial cable access method, and providing higher-speed and more stable data transmission. Different from FTTH (Fiber To The Home), FTTR further extends the end of the optical fiber network to meet the demand for high-speed networks within the home.

[0039] Wavelength Division Multiplexing (WDM): A technology for increasing the transmission capacity in an optical fiber network. By simultaneously transmitting multiple optical signals with different wavelengths in the same optical fiber, channel multiplexing is achieved. This method can greatly improve the bandwidth utilization rate of the optical fiber.

[0040] To solve the problem of poor transmission efficiency of communication signals in related technologies, the embodiments of the present application provide a method for downlink transmission of communication signals and a method for uplink transmission of communication signals. This method can run on Figure 1 the computer terminal shown below. The following describes this computer terminal.

[0041] The embodiments of the method for downlink transmission of communication signals or the method for uplink transmission of communication signals provided by the embodiments of the present application can be executed on a mobile terminal, a computer terminal, or a similar computing device. Figure 1 The following shows a hardware structure block diagram of a computer terminal for implementing the method for downlink transmission of communication signals or the method for uplink transmission of communication signals. As Figure 1As shown, the computer terminal 10 may include one or more processors (shown as 102a, 102b, ……, 102n in the figure) (the processor may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission module 106 for communication functions connected through a wired and / or wireless network. In addition, it may further include: a display, a keyboard, a cursor control device, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the I / O interface), a network interface, and a BUS bus. Those of ordinary skill in the art can understand that Figure 1 the structure shown is only schematic and does not limit the structure of the above-mentioned electronic device. For example, the computer terminal 10 may further include more or fewer components than Figure 1 shown in, or have a different configuration from Figure 1 that shown.

[0042] It should be noted that the above one or more processors and / or other data processing circuits are generally referred to as "data processing circuits" in this article. The data processing circuit may be embodied in whole or in part as software, hardware, firmware, or any combination thereof. In addition, the data processing circuit may be a single independent processing module, or be incorporated in whole or in part into any one of the other elements in the computer terminal 10. As involved in the embodiments of the present application, the data processing circuit is a kind of processor control (such as the selection of a variable resistor terminal path connected to an interface).

[0043] The memory 104 can be used to store software programs and modules of application software, such as program instructions / data storage devices corresponding to the downlink transmission method of communication signals or the uplink transmission method of communication signals in the embodiments of the present application. The processor executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implements the above-mentioned downlink transmission method of communication signals or the uplink transmission method of communication signals. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memories. In some instances, the memory 104 may further include a memory remotely set relative to the processor, and these remote memories can be connected to the computer terminal 10 through a network. Examples of the above network include, but are not limited to, the Internet, an enterprise intranet, a local area network, a mobile communication network, and combinations thereof.

[0044] The transmission module 106 is used to receive or send data via a network. Specific examples of the above-mentioned network may include a wireless network provided by the communication provider of the computer terminal 10. In one example, the transmission module 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission module 106 can be a Radio Frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0045] The display can be, for example, a touch-screen liquid crystal display (LCD), which enables the user to interact with the user interface of the computer terminal 10.

[0046] It should be noted here that in some alternative embodiments, the above Figure 1 illustrated computer terminal may include hardware elements (including circuits), software elements (including computer code stored on a computer-readable medium), or a combination of both hardware elements and software elements. It should be pointed out that Figure 1 is only an example of a specific specific instance and is intended to illustrate the types of components that may exist in the above computer terminal.

[0047] Under the above operating environment, the embodiments of the present application provide a method for downlink transmission of communication signals and a method for uplink transmission of communication signals. It should be noted that the steps illustrated in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is illustrated in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0048] Figure 2 is a structural diagram of an optical fiber network system according to an embodiment of the present application. As Figure 2 shown, the optical fiber network system 20 includes:

[0049] A converged master gateway 200, which is connected to an outdoor central office device 22 through a passive optical network and is used to receive communication signals generated by the central office device. Among them, the converged master gateway includes a wireless access unit 202 for accessing the communication signals of the central office device indoors, and the wireless access unit is a functional unit that supports the functions of an optical modem and a base station;

[0050] A converged optical splitter unit 204, which is connected to the converged master gateway through an optical fiber network and is used to distribute communication signals;

[0051] The integrated sub-gateway 206 is connected to the integrated optical splitter unit through an optical fiber network, and is used to receive the communication signals distributed by the integrated optical splitter unit and forward the communication signals to the user equipment 24 indoors.

[0052] Through the above optical fiber network system integrating the functions of an optical modem and a base station, the purpose of efficiently and accurately introducing wireless signals into the room and distributing coverage is achieved, thereby realizing the technical effects of optimizing the indoor wireless communication quality, reducing costs, and reducing signal interference, and further solving the technical problems of high base station construction costs, resource waste, and poor wireless coverage targeting existing in the outdoor blind compensation method in the related art.

[0053] Figure 3 It is a structural diagram of another optical fiber network system according to an embodiment of the present application. As Figure 3 shown, it more clearly shows the internal composition of the optical fiber network system. It includes three core parts: an integrated main gateway, an integrated optical splitter unit, and multiple integrated sub-gateways. Specifically, the integrated main gateway serves as the center of the system. It not only has the PON network access function of a traditional optical modem but also integrates the wireless communication function of a small base station. Through the optical fiber connection with the OLT device, it realizes the reception and processing of mobile communication network signals. The integrated main gateway mainly includes a wireless access unit (including Figure 3 the wireless small modem main gateway and the wireless small modem base station in it), a sub-gateway management module, an optical-electric conversion module, and a wavelength division multiplexing module. The integrated optical splitter unit divides the signals of the integrated main gateway into multiple paths through wavelength division multiplexing and optical splitting technologies, and each path of signal is connected to an integrated sub-gateway through an independent optical fiber to achieve distributed coverage of the signals. The integrated optical splitter unit mainly includes a wavelength division multiplexing A module, an optical splitter, an upstream aggregation unit, and a wavelength division multiplexing B module. Multiple integrated sub-gateway modules are responsible for converting the signals into a form suitable for indoor wireless communication and further expanding the signals through a micro-distribution unit to directly provide high-quality wireless network access services for indoor users. The integrated sub-gateway module mainly includes a wavelength division multiplexing module, a signal detection module, a sub-gateway module, and a micro-distribution remote module.

[0054] Figure 3An indoor wireless signal coverage solution is also presented. Specifically, in the initial stage, the Internet data stream enters the central office switching network and is then directed to the pico base station security gateway, and then enters the core network through the security gateway. Starting from the core network, the data communication signal is sent to the integrated master gateway to achieve the PON network connection with the OLT device. Inside the integrated master gateway, after the signal strength is dynamically adjusted by the sub-gateway management module, the signal is transmitted to the integrated optical splitter unit. The integrated optical splitter unit then distributes the signal to multiple integrated sub-gateways, and each sub-gateway is responsible for a specific area, such as a room or a living room. Among them, the integrated sub-gateway automatically adjusts the signal transmission power through the signal detection function module to adapt to the wireless environment of the area where it is located. At the same time, through the micro-distributed remote module inside it, the signal is converted into a wireless format and covered to every corner of the room. This process not only realizes the synchronous deployment of the fixed network and the wireless network, but also optimizes the indoor wireless signal coverage. Especially in scenarios such as villas and large shopping malls that require large-area coverage, it can effectively solve the signal blind area problem and improve the user experience.

[0055] The following combines Figure 2 and Figure 3 to elaborate in detail on the gateway structure in this distributed system.

[0056] Before that, it should be noted that on the basis of introducing wireless signals into the indoor environment, this application creatively integrates the functions of traditional optical modems and base stations. The integrated wireless device (which can be used as the wireless access unit in the integrated master gateway of this application) not only has the function of an optical modem but also has the function of a base station. The principle of this wireless device is as Figure 4 shown. The figure is divided into two parts. The left part shows the traditional network connection method, where a common optical modem is connected to the core network through the PON network and provides wireless coverage through a pico base station. The right part shows the wireless device proposed in this application, which integrates the functions of an optical modem and a base station, is directly connected to the core network through the PON network, provides indoor wireless coverage through Wi-Fi 6 and 4G technologies, and can realize the backhaul of the base station signal. This improvement can directly introduce wireless signals into the indoor environment, realize the synchronous deployment of the fixed network and the wireless network, and achieve the distributed coverage of indoor wireless signals through a small optical fiber network system.

[0057] Furthermore, the internal structure of the wireless device is as Figure 5As shown in the figure, it includes two main modules: the optical modem module and the base station module. Among them, the optical modem module includes: an ONU protocol stack, which is responsible for handling the communication protocols of the optical network unit; switching / routing, which is used to provide packet switching and routing functions; a service module, which supports various service types, such as IPTV, voice communication, and data storage, etc.; WiFi PHY and LAN PHY: which are respectively responsible for the physical layer processing of wireless and wired local area networks. The base station module includes: a network interface, which is an interface for network connection; a secure tunnel, which provides a secure encrypted channel for data transmission; L1 / L2 represents the data link layer in the OSI model; PHY represents the physical layer, which is responsible for the wireless signal processing of the base station; a radio frequency link, which is used to process the transmission and reception of radio frequency signals.

[0058] The above-mentioned optical modem module and base station module are connected through a gigabit network interface to achieve high-speed data transmission. The optical modem module is network-managed through a network management interface (TR069), and the base station module also has a corresponding network management interface (TR069) for management and configuration. The design of the entire wireless modem aims to achieve synchronous coverage of wireless signals and fixed networks through PON fibers, so as to improve the quality and coverage of indoor wireless communication.

[0059] In the embodiment of this application, the integrated main gateway mainly includes a wireless access unit (which can adopt the Figure 5 shown wireless modem device), a sub-gateway management module, an optical-electric conversion module, and a wavelength division multiplexing module. The functional modules and connection methods of this integrated main gateway are as Figure 6 shown. The specific analysis is as follows:

[0060] (1) The wireless access unit includes: an optical modem main gateway (i.e., the Figure 3 or Figure 6 wireless modem main gateway in Figure 3 or Figure 6 ), which is used to receive the communication signals of the central office equipment through a passive optical network; a base station module (i.e., the

[0061] wireless modem base station module in

[0062] ), which is connected to the optical modem main gateway and is used to convert the communication signals into wireless signals to achieve indoor wireless transmission. Among them,

[0063] (2) Sub - gateway management module: Responsible for collecting and analyzing information such as signal strength and room size from the integrated sub - gateway, and ensuring high - quality and high - efficiency indoor distributed coverage by dynamically adjusting the signal strength.

[0064] Optionally, the sub - gateway management module can also receive signal detection information from the integrated sub - gateway through the fiber - optic network, and adjust the signal strength of the communication signal based on the signal detection information. Among them, the signal detection information includes the coverage situation of the room where the integrated sub - gateway is located, and the signal interference situation between the integrated sub - gateway and adjacent sub - gateways.

[0065] In the embodiment of the present application, the sub - gateway management module can dynamically adjust the strength of the wireless signal to adapt to the specific requirements of the indoor environment, thereby improving the performance of the wireless network and the user experience. Specifically, the sub - gateway management module can receive signal detection information from the integrated sub - gateway through the fiber - optic network, including but not limited to the wireless signal coverage situation in the room where the sub - gateway is located, such as signal strength, coverage range, etc., and the signal interference situation between the sub - gateway and adjacent sub - gateways. Subsequently, based on the collected signal detection information, it intelligently adjusts the signal strength of the communication signal to ensure that sufficient signal coverage can be obtained in all areas of the room, while avoiding interference caused by excessive signal strength. For example, in an environment with a high density of users or many obstacles, stronger signal coverage may be required. Through the dynamic adjustment of the sub - gateway management module, a more uniform and optimized indoor wireless signal coverage can be achieved. Users will be able to enjoy a smoother and more stable wireless connection, whether they are performing daily web browsing or activities with high requirements for network quality, significantly improving the user experience.

[0066] (3) Optical - electrical conversion module: Connected to the base station module, responsible for converting the electrical signal generated by the base station module into an optical signal, and converting the optical signal transmitted by the external optical fiber into an electrical signal, ensuring effective conversion between electrical and optical signal forms.

[0067] (4) Wavelength - division multiplexing module: Connected to the optical - electrical conversion module, through wavelength - division multiplexing technology, multiplexes optical signals of different wavelengths onto the same optical fiber for transmission in a single down - link optical fiber. Among them, the uplink and down - link wavelengths carrying the ONT signal are 1310nm and 1490nm respectively, and the uplink and down - link wavelengths carrying the wireless signal are 1350nm and 1410nm respectively.

[0068] In the embodiments of the present application, the integrated optical splitting unit includes: a first wavelength division multiplexing module, connected to the wavelength division multiplexing module in the integrated main gateway through an optical fiber network, for receiving the optical signals sent down by the wavelength division multiplexing module; an optical splitter, for forwarding the optical signals received by the first wavelength division multiplexing module; a second wavelength division multiplexing module, connected to the optical splitter, for receiving the optical signals forwarded by the optical splitter; and connected to the integrated sub-gateway through an optical fiber network, for receiving the communication signals of the user equipment uploaded by the integrated sub-gateway; an upstream aggregation unit, connected to the second wavelength division multiplexing module, for aggregating the communication signals of the user equipment uploaded by the integrated sub-gateway. The functional modules and connection manners of the integrated optical splitting unit are as Figure 7 shown. The specific analysis is as follows:

[0069] (1) Wavelength division multiplexing A module: That is, the above-mentioned first wavelength division multiplexing module, responsible for multiplexing optical signals of different wavelengths into the downstream main optical fiber for transmission in a single optical fiber.

[0070] (2) Optical splitter: Divides the optical signals transmitted from the wavelength division multiplexing A module into four channels on average according to power, and each channel is connected to a wavelength division multiplexing B module.

[0071] (3) Wavelength division multiplexing B module: That is, the above-mentioned second wavelength division multiplexing module, there are four in total, corresponding to the downstream branch optical fibers 1 to 4 respectively. This wavelength division multiplexing B module is responsible for further processing the optical signals split by the optical splitter and connecting them to the corresponding downstream branch optical fibers to transmit the processed optical signals to the integrated sub-gateway.

[0072] (4) Upstream aggregation unit: Responsible for aggregating the communication signals (in the form of light) of the user equipment uploaded by the integrated sub-gateway and uploading them through the wavelength division multiplexing A module.

[0073] Among them, the red lines represent optical signals with wavelengths of 1310nm, 1490nm, 1350nm, and 1410nm, which are respectively used to carry different communication signals; the green line represents the optical signal with a wavelength of 1350nm; the blue lines represent the optical signals with wavelengths of 1310nm, 1490nm, and 1410nm.

[0074] Overall, the integrated optical splitting unit realizes the coexistence transmission of optical signals of different wavelengths in a single optical fiber through wavelength division multiplexing technology, thereby improving the utilization efficiency of the optical fiber. At the same time, through the collaborative work of the optical splitter and the wavelength division multiplexing module, the distribution and aggregation of optical signals are realized, providing a basis for the distributed coverage of indoor wireless signals.

[0075] In the embodiments of the present application, the integrated sub-gateway mainly includes a wavelength division multiplexing module, a signal detection module, a sub-gateway module, and a micro-distributed remote module. The functional modules and connection manners of the integrated sub-gateway are asFigure 8 As shown below. The specific analysis is as follows:

[0076] (1) Sub - gateway signal detection module: Responsible for detecting the signal status of the sub - gateway, including signal strength and quality, etc.

[0077] Specifically, this (sub - gateway) signal detection module is used to determine the signal detection information of the integrated sub - gateway and upload the signal detection information to the sub - gateway management module in the integrated main gateway through the optical fiber network.

[0078] Among them, determining the signal detection information of the integrated sub - gateway includes: obtaining the power information of the wireless signal emitted by the integrated sub - gateway; determining the spatial distribution of the integrated sub - gateway indoors; determining the signal strength between the integrated sub - gateway and adjacent sub - gateways; and determining the signal detection information based on the power information, spatial distribution, and signal strength.

[0079] In the embodiment of the present application, the signal detection module can provide a comprehensive signal detection information, which reflects the wireless signal coverage status and potential interference problems of the sub - gateway. Through the optical fiber network, these signal detection information are uploaded to the sub - gateway management module in the integrated main gateway. The sub - gateway management module uses this information to dynamically adjust the strength and distribution of the wireless signal to adapt to the changes in the indoor environment, ensuring the stability and coverage quality of the wireless network. This dynamic adjustment mechanism enables the system to intelligently respond to the changes in the indoor wireless communication environment, such as user movement, obstacle changes, etc., thereby providing a more stable and efficient wireless service. In this way, the system not only improves the utilization rate of wireless signals but also enhances the user's wireless network experience, especially in application scenarios that require high bandwidth and low latency.

[0080] (2) FTTR sub - gateway module: Provides 2 LAN ports and 2 WiFi ports for wired and wireless network connections.

[0081] (3) Wavelength - division multiplexing module: Connects to the integrated optical splitter unit through the down - link distribution optical fiber X and is used to process optical signals of different wavelengths. This wavelength - division multiplexing module can receive signals with wavelengths of 1310nm and 1490nm to achieve data transmission in the PON network; and transmit signals with wavelengths of 1410nm and 1550nm to the micro - distribution remote module to achieve specific communication services.

[0082] (4) Micro - distribution remote module (optical - electrical conversion): Responsible for converting optical signals into electrical signals so that the sub - gateway module can process them. This module is connected to 2 4G antennas for wireless signal transmission and reception.

[0083] In the embodiments of the present application, the fixed network and wireless communication functions are innovatively integrated. By integrating the base station function into the traditional optical modem, the "wireless modem" product is created, realizing in-depth indoor coverage of the mobile communication network signal. The system architecture includes a converged master gateway, a converged optical splitter unit, and a converged sub-gateway. Among them, the converged master gateway integrates a sub-gateway management module, which can dynamically adjust the signal strength and optimize the coverage effect; the converged sub-gateway has a new signal detection function and can automatically adapt to environmental changes. This design not only significantly reduces the cost and resource waste of covering indoors with traditional outdoor base stations, but also improves the pertinence and flexibility of signal coverage. It is especially suitable for scenarios such as residential communities, effectively solves the problem of indoor signal blind spots, improves the user experience, and enhances the competitiveness of operators. In addition, the system realizes distributed transmission of signals through a small optical fiber network, is applicable to environments such as villas and large shopping malls that require wide-area coverage, breaks through the limitation of the coverage range of a single device, realizes comprehensive indoor wireless signal coverage, and provides an economical, efficient, and flexible indoor wireless network solution.

[0084] Figure 9 is a flowchart of a downlink transmission method of a communication signal according to an embodiment of the present application, as Figure 9 shown, the method includes the following steps:

[0085] Step S902, obtain the communication signal of the central office device through the converged master gateway. Among them, the converged master gateway includes a wireless access unit for accessing the communication signal of the central office device indoors, and the wireless access unit is a functional unit that supports the functions of an optical modem and a base station.

[0086] In the above step S902, as the central device of the system, the converged master gateway can obtain the communication signal from the central office device (such as OLT) through its built-in wireless access unit, that is, a functional unit integrating the functions of an optical modem and a base station. It should be noted that this converged master gateway unit can not only process the PON signal of the fixed network, but also carry the wireless signal generated by the base station module, convert the electrical signal into an optical signal through optical-electric conversion, and lay a foundation for subsequent signal transmission.

[0087] Step S904, distribute the communication signal through the converged optical splitter unit.

[0088] In the above step S904, it is necessary to send the optical signal output by the converged master gateway into the converged optical splitter unit, and first combine the optical signals of different wavelengths through the wavelength division multiplexing module in the converged optical splitter unit, and then evenly distribute the signal power to four channels through the optical splitter module, and connect them to four wavelength division multiplexing B modules respectively to realize the initial distribution of the signal and expand the coverage range.

[0089] Step S906: Receive the communication signal distributed by the integrated optical splitter unit through the integrated sub-gateway, and forward the communication signal to the user device.

[0090] In the above step S906, after the integrated sub-gateway receives the communication signal from the optical splitter unit, the signal can be separated again through the wavelength division multiplexing module inside the sub-gateway, and the optical signals carrying FTTR (wavelengths 1310nm and 1490nm) and the optical signals carrying wireless signals (wavelengths 1350nm and 1410nm) are processed separately. Among them, the FTTR optical signal provides fixed network broadband access for users through the sub-gateway module, while the wireless signal is converted into a wireless format through photoelectric conversion and radio frequency circuit processing and finally covers the user device through the built-in micro-distributed remote module, such as mobile phones, laptops, etc. It should be noted that the signal detection function module in the sub-gateway can also automatically adjust the signal transmission power to adapt to different room sizes and structures to ensure effective signal coverage.

[0091] In the above steps S902 to S906, an efficient transmission path for signals from the central office to the user device is established through the small optical fiber network system, effectively solving the problem of indoor signal blind spots, while optimizing the signal strength and coverage effect, and providing more stable and comprehensive mobile and fixed network communication services for users.

[0092] Figure 10 is a flowchart of an uplink transmission method of a communication signal according to an embodiment of the present application. As Figure 10 shown, the method includes the following steps:

[0093] Step S1002: Obtain the communication signal of the user device through the integrated sub-gateway.

[0094] In the above step S1002, the user's communication signal, including fixed network and wireless signals, is first captured by the integrated sub-gateway. The micro-distributed remote module in the integrated sub-gateway receives the wireless signal from the user device, while the FTTR sub-gateway module receives the fixed network signal. These signals are then subjected to photoelectric conversion inside the sub-gateway to convert the received radio frequency signal into an optical signal, for example, converting the wireless signal optical with a wavelength of 1350nm and the fixed network signal optical with a wavelength of 1310nm.

[0095] Step S1004: Aggregate the communication signal through the integrated optical splitter unit.

[0096] In the above step S1004, the converted optical signal is connected to the integrated optical splitter unit through an optical fiber. Among them, the wavelength division multiplexing B module uploads these optical signals to the wavelength division multiplexing A module of the optical splitter unit. The upstream aggregation module receives and aggregates the 1350nm wireless signal light from four integrated sub-gateways, and the fixed network signal light is uploaded through the aggregation function of the optical splitter. The wavelength division multiplexing A module combines the optical signals of different wavelengths again to prepare for uploading to the main gateway.

[0097] Step S1006, receive the communication signal aggregated by the integrated optical splitter unit through the integrated main gateway, and upload the communication signal to the local device. Among them, the integrated main gateway includes a wireless access unit for backhauling the communication signal of the user equipment to the outside. The wireless access unit is a functional unit that supports the functions of an optical modem and a base station.

[0098] In the above step S1006, after the integrated main gateway receives the communication signal aggregated by the optical splitter unit, the photoelectric conversion module converts the optical signal back into an electrical signal. The base station module processes the wireless signal and backhauls it to the mobile communication network through the ANT interface, while the wireless optical modem module processes the fixed network signal and uploads it to the core network through the GPON interface. Among them, the sub-gateway management module can also dynamically adjust the signal strength according to the information fed back by the sub-gateway signal detection functional module to further optimize the signal upload quality.

[0099] In the above steps S1002 to S1006, the unique mechanism of the upstream signal transmission in this application is reflected, that is, the signal of the user equipment passes through the optical fiber network system, is processed and aggregated by the sub-gateway and the optical splitter unit, and finally is uploaded to the local device by the main gateway. This process not only realizes the efficient backhaul of the signal, but also ensures the stability and quality of the uploaded signal through dynamic signal strength adjustment.
