METHOD FOR HANDOVER OF TERMINAL USING MULTI-CONNECTION IN CELLULAR COMMUNICATION SYSTEM
First Claim
1. A method for handover of a terminal in a multi-beam environment, the method comprising:
- (a) measuring quality of a beam received from a second base station by a terminal receiving service of a first base station;
(b) performing random access to the second base station when the quality of the beam received from the second base station is equal to or greater than a predetermined critical value;
(c) setting a connection to the second base station in addition to a connection to the first base station when the random access to the second base station is successful; and
(e) transmitting/receiving data with the first terminal and the second terminal

Abstract
A method for handover of a terminal using a multi-connection in a cellular communication system is disclosed. The method for handover according to the present invention includes a multi-connection setting procedure of setting a connection to a second base station in addition to a connection to a first base station according to movement of a terminal in a direction from the first base station to the second base station, and a connection release procedure of releasing the connection to the first base station. Specifically, the present invention may be applied in a multi-beam management environment of super high frequency (SHF) and extremely high frequency (EHF) bandwidths, and may obtain an effect of decreasing signaling overhead and process latency of a conventional handover method.
