Failure Event Report Extension for Inter-RAT Radio Link Failure
First Claim
1. A method, comprising:
- detecting a failure event by a user equipment (UE) in a first cell served by a first base station in a wireless communication network, wherein the first cell belongs to a first radio access technology (RAT);
performing a radio resource control (RRC) establishment procedure with a selected second cell served by a second base station, wherein the second cell belongs to a second RAT; and
transmitting a failure event report to the wireless communication network, wherein the failure event report comprises logged information related to the failure event.

Abstract
A method of inter-RAT failure event report is proposed. A UE detects a failure event in a first cell served by a first base station, and the first cell belongs to a first RAT. The failure event may include a radio link failure or a handover failure. The UE then performs an RRC establishment procedure with a second cell served by a second base station, and the second cell belongs to a second RAT. After the RRC establishment, the UE transmits a failure event report to the wireless network. The failure event can be a radio link failure, or be associated with a mobility command such as a handover command. By providing more reliable information in the failure event report than a network solution could provide, inter-RAT mobility performance can be improved.
