METHOD AND APPARATUS FOR SUPPORTING HANDOFF FROM GPRS/GERAN TO LTE EUTRAN

摘要

PROBLEM TO BE SOLVED: To support handoff from GPRS/GERAN to LTE EUTRAN.SOLUTION: A method and apparatus for supporting an HO (handoff) from a GPRS (general packet radio service), a GERAN (global system for mobile communication radio access network), and an LTE (long term evolution) EUTRAN (evolved universal terrestrial radio access network) includes a step of receiving an LTE measurement report. An HO is initiated to the LTE network and a relocation request signal is transmitted. A relocation command signal that includes an eNB (evolved Node-B) ID (identifier) is received.
