MOBILE COMMUNICATION REMOTE WIRELESS EQUIPMENT SYSTEM USING BROADBAND NETWORK

摘要

The present invention relates to a communication method between a digital unit (DU) of a mobile communication base station and a radio unit (RU)/remote radio head (RRH), and is a technology for supplementing an existing system which must have an optical communication line between the DU and RRH and utilize a broadband network. A method according to the present invention provides a standard CPRI or an OBSAI interface and provides a system for receiving a signal come in from the interface and converting into Ethernet, GE-PON and xDSL signals which are appropriate for a broadband network through packet processing. As such, the restricted connection between the DU and the RRH is resolved and an already established wired internet infrastructure and a broadband network are able to be utilized.;COPYRIGHT KIPO 2014;[Reference numerals] (30,40) CPRI or OBSAI signal and broadband network packet conversion device;(AA,CC) Optical cable;(BB) Broadband network;(DD,EE) CPRI or OBSAI
