Technical Field

Background

A significant feature of the fifth generation (5th generation, 5G) mobile communication system compared with the fourth generation (4th generation, 4G) mobile communication system is the increased support for ultra-reliable and low-latency communications (URLLC) services. The types of services of URLLC include many, and typical use cases include industrial control, unmanned driving, telesurgery, smart grid, and the like. For URLLC traffic, a typical requirement is that 32 bytes of data are sent within 1 millisecond (ms) with a reliability of 99.999%. It should be noted that the above performance index is only an example, different URLLC services may have different requirements on reliability, for example, in some extremely harsh industrial control application scenarios, the transmission success probability of URLLC service data needs to reach 99.9999999% within 0.25 ms.

In a traditional networking system, each device transmits data through white light, each station can transmit data by using any frequency band in the white light, and with the development of communication technology, the data amount transmitted among the devices is increased, so that the transmission requirement of the data in the networking system cannot be met.

Detailed Description

The technical scheme provided by the embodiment of the application can be applied to various communication systems, such as: a Long Term Evolution (LTE) system, a fifth generation (5G) mobile communication system, a wireless fidelity (WiFi) system, a future communication system, or a system in which multiple communication systems are integrated, which is not limited in the embodiments of the present application. Among them, 5G may also be referred to as New Radio (NR).

A conventional Distributed Radio Access Network (DRAN) type networking, as shown in fig. 1, includes: the convergence device 101 and the plurality of stations (e.g., the station 102 and the station 103) may include any one of a baseband unit (BBU), an Active Antenna Unit (AAU)/Radio Remote Unit (RRU), and the like, where the stations are connected by an optical fiber, the stations and the convergence device are also connected by an optical fiber, the devices are connected by an optical fiber to form a ring for data transmission, the optical fiber transmits data by white light, and the stations and the optical fiber are connected by a Router (Router).

With the development of communication technology, the amount of data transmitted between devices increases, and the transmission requirement of data in a networking system cannot be met.

Referring to fig. 2, a networking system according to an embodiment of the present application includes:

the aggregation device 201 is connected to a plurality of stations (e.g., the station 2021 and the station 2022) via optical fibers, the stations and the aggregation device are also connected via optical fibers, the aggregation device may be a switch or a integrated access switch (LSW), and the stations may include a base station or other network devices. Currently, some examples of network devices are: a Node B (gnb) that continues to evolve, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) access point (access point, AP).

In this embodiment, the networking system uses color light for data transmission, and each station is connected to an optical fiber through a wavelength combiner (T2 module), as shown in fig. 3, the wavelength combiner can decouple a frequency band corresponding to a target station in the color light in the optical fiber, that is, a wavelength division part, and can also couple the frequency band of the target station to the color light, that is, a wavelength combination part, and each station uses a unique frequency band for data transmission, taking the color light in the optical fiber including 12 wavelengths, and the target station uses one of the wavelengths as an example, see fig. 4.

If the budget of the color light link is insufficient, an Optical Amplifier (OA) can be added at the color light inlet and outlet, as shown in fig. 5.

If the fiber is transmitting data via color and white light, a white light separator may be deployed through which the white light is separated from the color light, and the separated white light may be handed to a third party device for processing, see fig. 6, it being understood that OA may be added based on the deployment of the white light separator, as shown in fig. 7.

In the embodiment of the present application, the wavelength of the white light fluctuates within a certain range, and there is no specific standard wavelength, such as a client side optical port of the wavelength division device, and the corresponding interface is referred to as a white light interface, which may also be referred to as a gray light, and the common white light bands are 850nm and 1310 nm. The color light fluctuates in a small range near a certain central wavelength, can be connected with a wave combination device, has standard wavelength, and is a line single-board wavelength division side optical signal in a wavelength division system, and a corresponding interface is called a color light interface. Common color light bands include: the color light wavelength range for DWDM is 530nm-1565nm (C-BAND); the wavelength range of the color light used for CWDM is 1271nm-1611 nm. After connection channels (each connection channel uses an independent frequency band) are established between each station and the sink device, different stations may perform data transmission through the sink device, for example, when data transmission is performed between the station 2021 and the station 2022, if the station 2021 uses a first frequency band, the station 2022 uses a second frequency band, the station 2021 may send data to the sink device through the first frequency band, and after receiving, the sink device sends the data to the station 2022 through the second frequency band, and the station 2022 may receive the data of the first station through the second frequency band.

The same station may be connected to one or more terminal devices, for example, station 2021 is connected to terminal device 2031 and terminal device 2032, the number of the terminal devices is not limited, and terminal devices connected to different stations may perform data transmission through a networking system, for example, terminal device 2031 and terminal device 2033.
