Title:
MOBILE COMMUNICATION METHOD, MOBILE STATION, CORE NETWORK DEVICE, AND WIRELESS BASE STATION
Document Type and Number:
WIPO Patent Application WO/2012/157505
Kind Code:
A1
Abstract:
The present invention provides a remedy for when the quality of a wireless link in a Ud interface has degraded. In this mobile communication method, it is possible to switch between: a first communication state wherein the transmission/reception of a data signal is performed between a mobile station (UE#1) and a mobile station (UE#2) via a wireless link in a Ud interface set between the mobile station (UE#1) and the mobile station (UE#2) and not via a wireless link in a Uu interface set with respect to a wireless base station (eNB); and a second communication state wherein the transmission/reception of a data signal is performed between the mobile station (UE#1) and the mobile station (UE#2) via a wireless link in the Uu interface. The mobile station (UE#1) transitions to the second communication state when an RLF is detected in the Ud interface while in the first communication state.
