HANDOVER USING GROUP EVOLVED PACKET SYSTEM (EPS) BEARERS

摘要

Technology for a target evolved node B (eNB) operable to facilitate handover is disclosed. The target eNB can receive a handover request message to hand over a user equipment (UE) from the source eNB to the target eNB. The handover request message can include an evolved packet system (EPS) bearer group identifier (ID) indicating an EPS group bearer of the source eNB and associated with the UE, a last UE indicator to indicate whether the UE is a last UE of the source eNB to use the EPS group bearer, and a downlink (DL) traffic indicator to indicate whether the DL traffic for the UE during handover is negligible. The target eNB can perform a handover procedure to establish a connection with the UE based on at least one of the EPS bearer group ID, the last UE indicator, or the DL traffic indicator included in the handover request message.

1. A target evolved node B (eNB) operable to facilitate handover, the target eNB comprising one or more processors configured to:
receive, at the target eNB, a handover request message from a source eNB to hand over a user equipment (UE) from the source eNB to the target eNB, the handover request message including:
an evolved packet system (EPS) bearer group identifier (ID) indicating an EPS group bearer of the source eNB and associated with the UE;a last UE indicator to indicate whether the UE is a last UE of the source eNB to use the EPS group bearer; anda downlink (DL) traffic indicator to indicate whether the DL traffic for the UE during handover is negligible; and perform, at the target eNB, a handover procedure to establish a connection with the UE based on at least one of the EPS bearer group ID, the last UE indicator, or the DL traffic indicator included in the handover request message.
