Abstract

The embodiment of the invention relates to a switching optimization method between Home eNode B and eNode B in a next generation mobile communication system (LTE / LTE-Advanced). The method comprises the steps that: the eNode B and the Home eNode B acquire the velocity information and business state information (real-time business or non-real-time business) of a wireless transmitting / receiving unit (WTRU); and when the measurement result is lower than the threshold value, the switching judgment is made by comprehensively considering the load situation of a macro cell and a family base station cell in the LTE / LTE-Advanced as well as the velocity of the WTRU and the user business type. The method can optimize the switching a terminal between the macro cell and the family base station cell in the LTE / LTE-Advanced, thus improving the switching success rate and reducing unnecessary switching.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, more particularly, the present invention is used in the communication between eNodeB (evolved Node B) and Home eNodeB (Home Evolved Node B) in the next generation mobile communication system (LTE / LTE-Advanced) A handover optimization method. Background technique [0002] With the widespread commercialization of the third generation mobile communication system and the release of the LTE (Long Term Evolution) standard, the standard formulation of the fourth generation mobile communication system has also reached a critical stage. As the mainstream technology in the fourth generation mobile communication, 3GPP leads the formulation LTE-Advanced technology has high expectations. LTE-Advanced is the evolution of LTE. Its official name is Further Advancements for E-UTRA. It is one of the two mainstream technical solutions collected by ITU-R's IMT-Advanced. [0003] In LTE-Advanced...
