Abstract: PURPOSE: A method for supporting a vehicle communication handover is provided to perform a stable media access based on contention free through a WPCF(WAVE Point Coordination Function) channel access method. CONSTITUTION: A first RSU(Roadside Unit)(100a) receives vehicle information from a first vehicle(200a) which newly enters into a coverage of the first RSU. The first RSU transfers the channel access sequence to the first vehicle. If the first vehicle request a handover, the first RSU transfers the handover information about the first vehicle to a second RSU through a WAVE handover control unit. The second RSU receives the vehicle information from the first vehicle. According to the vehicle information, the second RSU allocates the vehicle access order.
Abstract translation: 目的：提供一种用于支持车辆通信切换的方法，以通过WPCF（WAVE Point Coordination Function）通道访问方法，基于无竞争性来执行稳定的媒体访问。 构成：第一RSU（路侧单元）（100a）从新进入第一RSU的覆盖范围的第一车辆（200a）接收车辆信息。 第一RSU将信道接入序列传送到第一车辆。 如果第一车辆请求切换，则第一RSU通过WAVE切换控制单元将关于第一车辆的切换信息传送到第二RSU。 第二RSU从第一车辆接收车辆信息。 根据车辆信息，第二RSU分配车辆访问命令。

Abstract: 복수의노변기지국을포함하는지능형교통시스템에서차량의핸드오버를지원하기위해복수의노변기지국중 제1 노변기지국은서비스영역에위치한적어도하나의차량중 새로진입한제1 차량으로부터차량정보를전달받는다. 그리고제1 노변기지국은차량정보에따라채널접속순서를결정하여제1 차량에게알린다. 제1 노변기지국은제1 차량이핸드오버를요청하는경우, WAVE 핸드오버제어부(WAVE Handover Controller)를통해제1 차량에대한핸드오버정보를복수의노변기지국중 제1 차량이진행하는방향에위치한제2 노변기지국으로전달되도록한다. 제2 노변기지국은서비스영역에진입한제1 차량으로부터차량정보를전달받는다. 제2 노변기지국은차량정보에따라채널접속순서를할당하여제1 차량으로알린다.
Abstract translation: 为了支持车辆在包括多个路边基站的智能交通系统中的交接，多个路边基站中的第一个从位于服务区域中的至少一个车辆中的新进入的第一车辆接收车辆信息 。 第一路边基站根据车辆信息确定信道连接顺序，并向第一车辆通知信道连接顺序。 当第一路边基站请求切换第一车辆时，第一路边基站通过WAVE切换控制器向第一路边基站发送关于第一车辆的切换信息 到第二个路边基站。 第二路边基站接收来自进入服务区域的第一车辆的车辆信息。 第二路边基站根据车辆信息分配信道连接顺序，并将信道连接顺序通知给第一车辆。

Abstract: PURPOSE: An apparatus and a method for vehicle communication handover support are provided to embody a stable media access based on contention free with the access method of a WPCF(WAVE Point Coordination Function) channel in handover. CONSTITUTION: A first RSU(Roadside Unit)(100a) receives vehicle information from a first vehicle(200a) which newly enters into. The first RSU transfers a channel connection order to the first vehicle. The first RSU transfers handover information about the first vehicle through a WAVE handover controller(310) to a second RSU(100b). The second RSU receives the vehicle information from the first vehicle. The second RSU transfers the channel connection order to the first vehicle.
Abstract translation: 目的：提供一种用于车辆通信切换支持的装置和方法，以便在切换中利用WPCF（WAVE Point Coordination Function）信道的访问方式，基于无争用地体现稳定的媒体接入。 构成：第一RSU（路侧单元）（100a）从新进入的第一车辆（200a）接收车辆信息。 第一RSU将通道连接顺序传送到第一车辆。 第一RSU通过WAVE切换控制器（310）将关于第一车辆的切换信息传送到第二RSU（100b）。 第二RSU从第一车辆接收车辆信息。 第二RSU将通道连接顺序传送到第一车辆。
