Embodiment Construction

[0026] In the following description of the embodiments of the present disclosure, when it is known that detailed descriptions of functions or configurations may unnecessarily obscure the subject matter of the present disclosure, it is determined that the detailed descriptions incorporated herein will be omitted. Hereinafter, embodiments according to the present disclosure will be described with reference to the accompanying drawings.

[0027] A multi-carrier mobile communication system according to an embodiment of the present disclosure includes an eNB and a UE capable of using at least two carriers. In particular, in a call connection, the UE is configured to use at least one carrier provided by the eNB according to UE information. Therefore, in a mobile communication system according to an embodiment of the present disclosure, it is possible to reduce a connection attempt rate of an overloaded cell in a call connection.

Abstract

The present invention relates to a method and apparatus for distributing idle UE carriers by carrier in an eNB of a multi-carrier based mobile communication system. The method for distributing idle UEs in a multi-carrier-based mobile communication system according to the present invention includes: a process of determining a search rate per carrier based on information representing a load on a carrier, and determining cell reselection with respect to an idle UE based on the determined search rate Priority steps, and the process of sending the determined cell reselection priority to the idle UE.

Description

technical field [0001] The present disclosure relates to a mobile communication system, and more particularly, to a user equipment (UE) (hereinafter referred to as "UE") in which an evolved Node B (eNB) of a multi-carrier based mobile communication system is in an idle mode according to carrier distribution. Idle UE") method and device. Background technique [0002] In a conventional 3GPP (3rd Generation Partnership Project) system, an eNB has one carrier for each cell, and a UE accesses the one carrier to receive a service. In a conventional 3GPP system, the UE's cell selection process and RRC (Radio Resource Control) connection setup process are as follows. [0003] In initial startup or change in radio frequency environment, UE searches for the most suitable cell through cell selection / reselection process, receives system information from eNB of the searched cell, and camps on the searched cell. Then, when initiating a call or performing a paging procedure in the networ...
