SYSTEM AND METHOD FOR IDENTIFYING TARGET DENB CELL
First Claim
Patent Images
1. A system for identifying a target base station cell, the system comprising:
- a plurality of donor base stations positioned on a predetermined track in which a moving object moves, and configured to set a downlink backhaul subframe corresponding to a backhaul link operated at the same frequency as that of an access link by combining two basic downlink backhaul subframe patterns on the basis of a plurality of basic downlink backhaul subframe patterns;
a relay node operation and management server configured to transmit cell list information corresponding to the plurality of donor base stations; and
a mobile relay node managed in an inband manner, and configured to perform cell camping to a cell of a first donor base station based on the cell list information, and to identify a cell of a second donor base station to perform handover from the cell of the first donor base station based on the downlink backhaul subframe.

Abstract
Disclosed are a system and a method for identifying a target DeNB cell for handing over to the target DeNB cell during an inband operation of 3GPP(3rd Generation Partnership Project) REL-12 mobile relay node. A donor DeNB combines two basic downlink backhaul subframe patterns on the basis of the basic downlink backhaul subframe patterns to configure a downlink backhaul subframe pattern corresponding to a backhaul link operated at the same frequency as that of an access link, and identifies the target donor DeNB cell for handing over on the basis of the downlink backhaul subframe.

6. A method for identifying a target base station cell, the method comprising:
-
a) performing cell camping to a cell of a first donor base station based on cell list information of a plurality of donor base stations positioned on predetermined tracks in which a moving object moves; and b) identifying a cell of a second donor base station to perform handover from the cell of the first donor base station based on a down link backhaul subframe, which is configured by combing two basic downlink backhaul subframe patterns on the basis of a plurality of basic downlink backhaul subframe patterns and corresponds to a backhaul link operated at the same frequency as that of an access link. - View Dependent Claims (7, 8, 9, 10)
