Abstract:
The present invention is related to a method and apparatus for facilitating lossless handover in a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a source evolved Node B (eNB), a target eNB, and a mobility management entity/user plane entity (MME/UPE) where the WTRU is in wireless communication with the source eNB. The source eNB determines to handover the WTRU to the target eNB, requests status reports from the WTRU, and requests handover to the target eNB. The handover request includes context information relating to the WTRU which is sent to the target eNB. The target eNB configures resources for the WTRU and transmits a handover response signal to the source eNB. The source eNB commands the WTRU to perform a handover to the target eNB and forwards data to the target eNB. The WTRU performs the handover to the target eNB.
