Definitions

  • the X2AP layer function in the radio base station DeNB 2 is configured so as to convert the control signal (X2AP signal) involved in the handover process between the relay node RN 2 and the radio base station DeNB 2 , and the control signal (X2AP signal) involved in the handover process between the relay node RN 3 and the radio base station DeNB 2 .
  • the relay node RN 3 upon receiving the “HO Request”, stores the “UE Context” of the mobile station UE in step S 2005 , and transmits an “HO Request Ack (handover request acknowledgement signal)” to the radio base station DeNB 2 via the X2-C radio bearer in step S 2006 .
  • HO Request Ack handover request acknowledgement signal
