  • Patent number: 9973990
    Abstract: A method and apparatus for transmitting a handover report message in a wireless communication system is provided. In a heterogeneous network (HetNet) intra long term evolution (LTE) failure case, an eNodeB (eNB) performs a handover procedure for a user equipment (UE) with a source eNB, and receives a radio link failure (RLF) indication message. The eNB transmits a handover report message to the source eNB, the handover report message including UE history information element (IE) of the UE.
    Type: Grant

  • Patent number: 9532278
    Abstract: A method and apparatus of performing a handover procedure in a wireless communication system is provided. The target eNodeB (eNB) receives a specific establishment cause of a user equipment (UE). The specific establishment cause among a plurality of establishment causes comprises emergency, high priority access, mobile terminated access, mobile oriented signaling, mobile oriented data, and delay tolerant access. The target eNB transmits a handover command message to the UE after receiving the specific establishment cause.

  • Patent number: 9474008
    Abstract: A method and apparatus for indicating a handover in a wireless communication system is provided. A mobile relay node (RN) receives an indication which indicates that there is no eNB supporting relay within neighbor cells from a donor eNodeB (eNB) serving the mobile relay node, and transmits a handover command message to user equipments (UEs).

  • Patent number: 9467915
    Abstract: A method and apparatus for transmitting a handover report message in a wireless communication system is provided. A first eNodeB (eNB) serves a first cell which is a coverage hole compensating cell between a source cell and a second cell, and a user equipment (UE) is moving from the source cell to the second cell through the first cell. The first eNB performs a handover procedure for a user equipment (UE) with a source eNB serving the source cell, receives a radio link failure (RLF) indication message from a second eNB serving the second cell, and transmits a handover report message to the source eNB, the handover report message including an indicator which informs the radio link failure.

  • Patent number: 9432930
    Abstract: A method and apparatus for transmitting a list of bearers in a wireless communication system is provided. A first eNodeB (eNB) of an energy saving cell configures a list of minimum required evolved-UMTS terrestrial radio access network (E-UTRAN) radio access bearers (E-RABs) or required E-RABs, and transmits the configured list of minimum required E-RABs or a required E-RABs to a second eNB of a compensation cell. Upon receiving the configured list of minimum required E-RABs, the second eNB checks whether the compensation cell is able to provide all E-RABs included in the list of minimum required E-RABs or not. Upon receiving the configured list of required E-RABs, the second eNB checks whether the compensation cell is able to provide E-RABs included in the list of required E-RABs or not.
