APPARATUS AND METHOD FOR REESTABLISHING RADIO LINK IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention discloses an apparatus and method for performing radio link reestablishment in a wireless communication system. Furthermore, the present invention discloses a radio link reestablishment request message, including a reestablishment cause indicator on which whether a Radio Link Failure (RLF) was generated by User Equipment (UE) is determined, a cause of the occurrence of the RLF is determined, and whether the cause of the radio link reestablishment is In-Device Coexistence interference (IDC) due to the UE. Accordingly, a network may know a cause of the occurrence of an RLF generated during a handover. In particular, the network may know whether the cause of the occurrence of the RLF is a handover failure or RLF due to IDC. Consequently, a radio link can be efficiently reestablished, and also network parameters can be controlled.
