Abstract: 본 발명은 이동 통신 시스템 및 방송시스템에서, 미래형 기지국(ABS: Advanced Base Station)이 브로드캐스트 버퍼링 컨텐츠(broadcast buffering contents)의 버퍼링 데이터 패킷을 주기적으로 브로드캐스트하며, 상기 브로드캐스트 버퍼링 컨텐츠는 미리 설정되어 있는 버퍼링 용량에 상응하는 버퍼링 데이터 패킷이 주기적으로 브로드캐스트되는 컨텐츠를 나타내며, 상기 버퍼링 데이터 패킷은 상기 브로드캐스트 버퍼링 컨텐츠가 미래형 이동 단말기(AMS: Advanced Mobile Station)들로 실제 제공되기 전에 미리 버퍼링되기 위한 목적으로 송신되는 데이터 패킷을 나타냄을 특징으로 한다.

Abstract: PURPOSE: A base station, mobile station, and operation method thereof are provided to offer synchronization information by effectively synchronizing a relay candidate mobile station with a mobile station which requests an emergency call. CONSTITUTION: A base station(200) recognizes an emergency situation of a neighbor base station. The base station broadcasts the emergency situation notification information of the neighbor base station to one or more mobile stations(300) within service coverage. The base station broadcasts location calculation information. The location of the mobile station is calculated based on the location calculation information. In case the mobile station is located a cell edge of a neighbor base station direction, the mobile station broadcasts an emergency situation preamble.
Abstract translation: 目的：提供一种基站，移动站及其操作方法，通过有效地使中继候选移动台与请求紧急呼叫的移动台同步来提供同步信息。 构成：基站（200）识别邻近基站的紧急情况。 基站向业务覆盖范围内的一个以上的移动台（300）广播邻居基站的紧急情况通知信息。 基站广播位置计算信息。 基于位置计算信息来计算移动站的位置。 在移动台位于相邻基站方向的小区边缘的情况下，移动台广播紧急状况前导码。

Abstract: PURPOSE: A relay method of a terminal for communication of an emergency terminal in a mobile communication system is provided to enable a terminal within cell coverage to set up an emergency call. CONSTITUTION: Terminals are converted in an emergency call relay standby mode(S310). The terminals are synchronized with a base station(S320). The terminals are switched into an emergency call relay mode(S340). The terminals transmit a resource request message to the base station(S350). The terminals transmits a connection setup message to the emergency terminal(S370). The base station and the emergency terminal transmit data through a relay terminal(S390).
Abstract translation: 目的：提供移动通信系统中紧急终端通信终端的中继方法，使得小区覆盖范围内的终端能够建立紧急呼叫。 规定：终端在紧急呼叫中继待机模式下转换（S310）。 终端与基站同步（S320）。 终端切换到紧急呼叫中继模式（S340）。 终端向基站发送资源请求消息（S350）。 终端向紧急终端发送连接建立消息（S370）。 基站和应急终端通过中继终端发送数据（S390）。

Abstract: PURPOSE: A device and method for proving a mobile IP television service in a mobile communication system and broadcasting system thereof are provided to minimize a unicast transmission rate. CONSTITUTION: An ABS periodically broadcasts a buffering data packet corresponding to buffering capacity about broadcast buffering content(313). The request for provision of content channel is received from an AMS(315). The requested content channel is a content channel which reproduces broadcast buffering content(317). The ABS transmits a residual data packet to the AMS(321).
Abstract translation: 目的：提供用于在移动通信系统及其广播系统中验证移动IP电视服务的装置和方法，以最小化单播传输速率。 构成：ABS周期性地广播与广播缓冲内容相关的缓冲容量对应的缓冲数据包（313）。 从AMS（315）接收到提供内容频道的请求。 所请求的内容频道是再现广播缓冲内容的内容频道（317）。 ABS向AMS发送残余数据包（321）。
