OAM APPARATUS FOR RADIO BASE STATION

摘要

The present invention relates to an OAM apparatus (150) for a radio base station (100).The OAM apparatus comprises an OAM receiver configured for receiving an electronic code key (345). The apparatus also comprises a storage unit comprising a list of code keys of which at least one of said code keys is valid. The apparatus further comprises a processing unit configured for determining whether a received code key, received by the OAM receiver, is comprised in said list in the storage unit and whether said received code key is valid, and for invalidating said received code key in said list for preventing repeated use of the code key if it has been determined that the received code key is valid. The apparatus also comprises an OAM transmitter configured for being in a silent unless activated to an active mode, where said transmitter is allowed to wirelessly transmit signals, in response to the OAM apparatus receiving an unlock signal (346). The OAM apparatus is configured for wireless communication with an OAM terminal (300) over a wireless OAM link (420)if it has been determined that the received code key is valid and if the OAM transmitter has been activated.
