摘要：
A method and system for efficient DRX operation during handover in LTE_ACTIVE in which a user equipment expects handover to occur, the method having the steps of: checking (114,314) whether a no handover initiation decision is received within a predetermined time period; if no, performing the steps of: ensuring (118,320) the user equipment is not in a DRX sleep period during reception of a handover grant; checking (120,322) whether a handover grant is received, and if yes, performing (122,330) a handover procedure; and if no, resuming (125,340) a DRX sleep interval; and if yes, ending (116,316) the process.
