APPARATUS AND METHOD FOR MANAGING MULTI-WAVELENGTH RESOURCE OF SEPARATE-TYPE BASE STATION OPTICAL LINK
First Claim
1. A digital unit comprising:
- one or more remote apparatus communicators configured to correspond to each of one or more remote apparatuses to process transmitted and received data;
a multi-wavelength controller configured to convert data transmitted from each of the one or more remote apparatuses into a wavelength allocated thereto and to transmit the converted data to remote apparatuses via an optical fiber; and
a base station controller configured to allocate transmission and reception wavelength to each of the one or more remote apparatus communicators to control the multi-wavelength controller and to transmit wavelength information associated with the wavelength allocation to each of the one or more remote apparatuses.

14. A method of managing multi-wavelength resources of a separate-type base station optical link, the method performed by a digital unit and comprising:
-
monitoring a threshold of a reference parameter according to an operation policy; in response to the monitored threshold being greater than a threshold used to determine whether to additionally allocate a wavelength, determining whether there is an idle wavelength for optical transmission and reception; and in response to a determination that there is an idle wavelength for optical transmission and reception, transmitting information for controlling wavelength allocation to a remote apparatus. - View Dependent Claims (15, 16)
