Abstract: PURPOSE: A device and a method capable of providing continuity of multicast service are provided to minimize cut of the multicast service when inter-cell occurs on a sleep mode terminal receiving the multicast service. CONSTITUTION: A wireless bearer information receiver unit(310) periodically receives the wireless bearer information about the multicast service from the source base station and stores it. If the hand over occurs among the reception of the multicast service packet, a service support decision unit(320) decides the multicast service support of a target base station. In case the target base transceiver station supports the multicast service, a wireless bearer information setting unit(330) sets the wireless bearer information about the recently received multicast service.

Abstract: A handover method for preventing time delay according to signal exchange between base stations is provided to perform handover through radio resources allocated without signal exchange, thereby performing efficient handover. A source base station sets or releases a user plane route between each neighbor BTS(Base Station) and an access gateway. The source base station stores radio resource information of each neighbor BTS(S100). When a determined target base station is registered in user plane route setting information, the source base station performs handover without signal exchange with another target base station(S200).
Abstract translation: 提供了一种用于根据基站之间的信号交换来防止时间延迟的切换方法，以通过在没有信号交换的情况下分配的无线资源来执行切换，由此执行有效的切换。 源基站在每个相邻BTS（基站）和接入网关之间设置或释放用户平面路由。 源基站存储各相邻BTS的无线资源信息（S100）。 当确定的目标基站被登记在用户平面路由设置信息中时，源基站执行与另一目标基站的信号交换的切换（S200）。

Abstract: A method for managing radio resources in a mobile communication system and a system thereof are provided to adjust sizes of adjacent cells by cell breathing to distribute a load of a cell, thereby enabling a larger number of user terminals to provide a service. A base station controller performs handover from cell B to cell A when the first user terminal(110) moves from a handover area(30) to a cell A area completely. The base station controller maintains zone connection about a user existing in an interval where maximum radiuses of two cells are overlapped. The base station controller applies the same cell radius to a newly join user through cell breathing.
