Title:
APPARATUS AND METHOD FOR DETECTING CAUSE OF RADIO LINK FAILURE OR HANDOVER FAILURE IN MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/039586
Kind Code:
A1
Abstract:
A terminal, a Base Station (BS) and a method for detecting a cause of a Radio Link Failure (RLF) or handover failure are provided. The method includes determining whether an RLF or a handover failure occurs, performing a process of a connection re-establishment or connection establishment to enter a connection mode after encountering the RLF or the handover failure, and transmitting an RLF information report to a BS after entering the connection mode.
