Abstract: The present invention relates to a method in which a primary component carrier (PCC) for user equipment (UE) in a multiple component carrier system is selected by an eNB. The method comprises the following steps: obtaining mobility condition information about the UE and coverage information and load information about carriers managed by the eNB; determining whether a mobility condition value of the UE is greater than a specific threshold, based on the obtained mobility condition information; and selecting the PCC based on the load information if, as a result of the determination, the mobility condition value is greater than the specific threshold. According to the present invention, a base station adaptively selects a PCC by taking the load state of a carrier (or cell), UE velocity, and the coverage of the carrier (or cell) into consideration. Accordingly, load balancing can be achieved, and a load due to the unnecessary handover and handover signaling of UE can be reduced. Moreover, all secondary component carriers (SSC) can be prevented from being configured (or reconfigured) after all the SSCs are released due to the frequent change of a PCC.

Abstract translation: 本发明涉及一种由eNB选择用于多分组载波系统中的用户设备（UE）的主分量载波（PCC）的方法。 该方法包括以下步骤：获取关于UE的移动性状况信息和覆盖信息，并载入关于eNB所管理的载波的信息; 基于所获得的移动性条件信息，确定所述UE的移动性状况值是否大于特定阈值; 以及作为所述确定的结果，所述移动性条件值大于所述特定阈值，则基于所述负载信息来选择所述PCC。 根据本发明，考虑到载波（或小区）的载波状态，UE速度和载波（或小区）的覆盖范围，基站自适应地选择PCC。 因此，可以实现负载平衡，并且可以减少由于UE的不必要的切换和切换信令引起的负载。 此外，由于PCC的频繁变化，可以防止在所有SSC被释放之后，所有次要分量载波（SSC）被配置（或重新配置）。

Abstract: The present invention relates to a method and an apparatus for traffic control which can be adopted for a next generation mobile communications system. The method comprises the following steps: determining whether a load state of a cell is greater than a threshold; if the load state is greater than the threshold, determining some terminals available for D2D communications among terminals connected to the cell; performing a D2D communication configuration for the terminal available for D2D communications; determining terminals available for handover among the remaining terminals which are not available for D2D communications; and performing a handover communication configuration for the terminals available for handover. According to the present invention, D2D direct communications are preemptively provided to terminals available for D2D communications before forcedly performing handover of terminals receiving a service from an existing cell in order to perform efficient traffic control when there is an overload on a network, thereby preventing signaling overload resulting from concurrent handover of a number of terminals or traffic congestion in a target cell.
