Embodiment Construction

[0057] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0058] The wireless fronthaul interface signal may include a common public radio interface (Common Public RadioInterface, CPRI) signal, an eCPRI signal (for example, including an Ethernet CPRI signal or an enhanced CPRI signal), a next-generation fronthaul interface (Next-Generation Fronthaul Interface, NGFI) signal Wait. The embodiment of the present invention can use FlexE as the fronthaul network to transmit the wireless fronthaul interface signal, and can also use other types of bearer networks, such as PON, OTN, wavelength division multiplexing network (Wavelength Division Multiplexing, WDM), Ethernet (Ethernet) and so on to transmit the wireless fronthaul interface signal. In the embodiment of the present invention, the FlexE carrying the CPRI signal is taken as an example for description. The principle of using FlexE to carry other types of wireless fro...

Abstract

The embodiments of the invention disclose a method for transmitting wireless interface forwarding signals, a network device and a network system. The method comprises the following steps that: a network device acquires wireless forwarding interface signals, wherein the wireless forwarding interface signals include a plurality of coding blocks; the wireless forwarding interface signals are mapped into the service layer time slots of M flexible Ethernets (FlexEs), so that FlexE signals can be generated, wherein the service layer time slots of the FlexE are determined according to the rate of thewireless forwarding interface signals, and M is a positive integer greater than or equal to 1; and the FlexE signals are sent to one or more physical channels. With the method, network device and network system of the invention adopted, the wireless forwarding interface signals such as CPRI, eCPRI and NGFI signals are carried through the FlexEs; and the service layer time slots of the FlexEs aredivided according to the rate of the wireless forwarding interface signals, and therefore, the bandwidth utilization of forwarding FlexE interfaces and the transmission efficiency of the wireless forwarding interface signals can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for transmitting wireless fronthaul interface signals. Background technique [0002] Currently, the Optical Internet Forum (OIF) is discussing the expansion of traditional Ethernet application scenarios, and proposed the Flexible Ethernet (FlexE) technology to support sub-rate, channelization, and inverse multiplexing for Ethernet services. and other functions. [0003] Since Ethernet is widely used as service interfaces in access networks and metropolitan area networks, FLexE based on Ethernet technology has the function of service flow aggregation and can realize seamless connection with Ethernet interfaces of the underlying service network. The introduction of FlexE's sub-rate, channelization, and inverse multiplexing functions greatly expands the application occasions of Ethernet, enhances the flexibility of Ethernet applications, and makes Ether...
