Abstract

The invention provides a handover method for an LTE (long term evolution) mobile communication system and a corresponding eNB node. The method comprises the following steps of: configuring measurement requests which are relevant to parameter setting of a measurement report for triggering handover preparation and of a measurement report for triggering the handover for UE (user equipment); receiving a measurement report which is from the UE and is used for triggering the handover preparation; judging for handing over according to the received measurement report for triggering the handover preparation; acquiring radio resource control connection reconfiguration information related to handover; storing the radio resource control connection reconfiguration information; receiving a measurement report which is from the UE and is used for triggering the handover; providing the stored radio resource control connection reconfiguration information to the UE to start the handover; and releasing the related resource after successful handover is carried out.

Description

technical field [0001] The present invention relates to a 3GPP Long Term Evolution (Long Term Evolution, LTE for short) mobile communication system, and specifically relates to a handover technology in the LTE mobile communication system. Background technique [0002] LTE technology is the evolution of the third generation mobile communication technology 3G, and it is the transition between 3G technology and 4G technology. [0003] figure 1 A schematic diagram showing the general architecture of an LTE mobile communication system. like figure 1 As shown, the LTE communication network system usually adopts a two-layer flat network architecture, including an access network E-UTRAN composed of eNodeB (hereinafter referred to as eNB) nodes, and a mobility management entity (Mobility Management Entity, referred to as MME) and serving gateway ( An evolved packet core network (Evolved Packet Core network, EPC for short) node composed of a Serving Gateway (SGW for short). The ac...
