HANDOVER-RELATED RADIO LINK FAILURE DETECTION
First Claim
1. A method for operating a Base Station (BS) for detecting a too early HandOver (HO)-related Radio Link Failure (RLF) in a wireless communication system, the method comprising:
- receiving an HO request from another BS for a User Equipment (UE) that has an established connection with the BS;
receiving a connection reestablishment request from the UE after an HO of the UE to the other BS has been performed;
determining if the connection reestablishment request is received prior to the expiration of a timer; and
if it is determined that the connection reestablishment request is received from the UE prior to the expiration of a timer, determining that an RLF occurred due to a too early HO triggering.

Abstract
A Base Station (BS) apparatus, for detecting a HandOver (HO)-related Radio Link Failure (RLF) in a wireless communication, and method for its operation, are provided. The method includes receiving an HO request from another BS for a User Equipment (UE) that has an established connection with the BS, receiving a connection reestablishment request from the UE after an HO of the UE to the other BS has been performed, determining if the connection reestablishment request is received prior to the expiration of a timer, and if it is determined that the connection reestablishment request is received from the UE prior to the expiration of a timer, determining that an RLF occurred due to a too early HO triggering.

10. A Base Station (BS) apparatus for detecting a too early HandOver (HO)-related Radio Link Failure (RLF) in a wireless communication system, the apparatus comprising:
-
a first receiver for receiving signals from another BS; a second receiver for receiving signals from a User Equipment (UE); a controller for controlling to receive an HO request via the first receiver from the other BS for the UE that has an established connection with the BS, for controlling to receive via the second receiver a connection reestablishment request from the UE after an HO of the UE to the other BS has been performed, for determining if the connection reestablishment request is received prior to the expiration of a timer, and if it is determined that the connection reestablishment request is received from the UE prior to the expiration of a timer, for determining that an RLF occurred due to a too early HO triggering. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
