Abstract
The present invention relates to radio communications technologies and discloses a method, an apparatus, and a system for sending a data packet to avoid repeated forwarding of data when a user equipment hands over between an access point and an evolved NodeB. The method includes: receiving, by an evolved NodeB, a data packet sent by a core network and sending the data packet to a current access point; and keeping caching the data packet on the evolved NodeB before determining that a user equipment has correctly received the data packet from the current access point. The present invention is applicable to data transmission in a network.
