Abstract

The invention discloses a method and a device for carrying data, and a method and a device for analyzing data, which relate to the technical field of optical communication and are invented in order to solve the problem of large time delay existing in the prior art. Wherein, the data bearing method includes: receiving m channels of general public radio interface CPRI services, wherein m is an integer greater than 1; mapping the received m channels of CPRI services to m channels of optical channel data branches in a one-to-one manner In the unit; multiplex the m-channel optical channel data tributary unit carrying the CPRI service into the time slot of the optical channel payload unit; wherein, the rate of the time slot is equal to the basic rate of CPRI. The invention is applied in the transmission process of CPRI service.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a method and device for data bearing and a method and device for data analysis. Background technique [0002] At present, distributed base stations are more and more widely used. Compared with the traditional macro base station, the distributed base station separates the indoor baseband processing unit (English: Building Base band Unit, referred to as BBU) and the remote radio unit (English: RadioRemote Unit, referred to as: RRU), and the BBU and RRU pass through fiber optic connection. Therefore, the baseband data (hereinafter referred to as CPRI service) from the Common Public Radio Interface (English: Common Public Radio Interface, CPRI for short) needs to be transmitted through an Optical Transport Network (English: Optical Transport Network, OTN for short). Among them, the OTN network electrical layer technical specification defines three levels of op...
