    • A method and apparatus for supporting mobility in a mobile broadcasting system in which Electronic Service Guide (ESG) discovery is required. The mobility support is classified into three ways. The first way is to provide roaming information for a local IPDC operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with type information of an ESG, an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the type information of the ESG, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.
    • 一种在需要电子业务指南(ESG)发现的移动广播系统中支持移动性的方法和设备。 流动性支持分为三种方式。 第一种方法是为本地IPDC运营商中具有漫游合作伙伴的本地IPDC运营商提供漫游信息。 在第二种方式中,终端发送用于请求传输关于特定本地IPDC运营商的信息的查询消息,并且响应于此接收关于特定本地IPDC运营商的信息。 第三种方式是向终端提供ESG的类型信息,其接入类型根据漫游业务的提供进行分类。 可以在ESG引导级别中提供漫游信息,关于特定本地IPDC运营商的信息以及从移动广播系统提供给终端的ESG的类型信息。

    • PROBLEM TO BE SOLVED: To prevent the waste of bandwidth by effectively utilizing, at a maximum, one transmission cycle in synchronous Ethernet(R). SOLUTION: When transmitting asynchronous data, a size (L2) of the asynchronous data to be transmitted is compared with a size (L1) of a transmission space vacant in an asynchronous frame part of a transmission frame and if the size (L2) of the asynchronous data is equal to or less than the size (L1) of the transmission space, the asynchronous data are inserted into the transmission space and transmitted. If the size (L2) of the asynchronous data is larger than the size (L1) of the transmission space, the asynchronous data are segmented to fit the size (L1) of the transmission space, and inserted into the asynchronous frame including a More flag field indicating segmentation/ transmission and further, segmented remaining asynchronous data (L2-L1) are inserted into a transmission frame of the next transmission cycle and transmitted.

    • 要解决的问题:通过在同步以太网(R)中最大限度地利用一个传输周期来防止带宽的浪费。 解决方案:当发送异步数据时,要发送的异步数据的大小(L2)与传输帧的异步帧部分中空闲的传输空间的大小(L1)进行比较,如果大小(L2 )等于或小于传输空间的大小(L1),异步数据被插入到传输空间中并被发送。 如果异步数据的大小(L2)大于传输空间的大小(L1),则异步数据被分段以适应传输空间的大小(L1),并插入到包括更多标志的异步帧 指示分割/发送的场,并且进一步将分段的剩余异步数据(L2-L1)插入到下一个发送周期的发送帧中并发送。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a method for selecting a bridge device which communicates between different piconets in a high-speed wireless personal area network (WPAN) using an ultra wide band (UWB). SOLUTION: The wireless personal area network comprises a parent piconet (PN) formed by a plurality of devices and a child piconet (PN) using a time slot allocated by a device within the parent PN. It has a bridge device which transmits data between a device within the child PN and a device within the parent PN by broadcasting information on devices in the parent PN and the child PN to each device within the WPAN. An MAC frame used by the bridge device contains a field indicating the whole capability value of a specific device, a field indicating the length of the frame, and an element ID field for identifying each element. The whole capability value field includes a field indicating a specific capability value, a field indicating adaptability if the device can be a piconet coordinate (PNC), and a field indicating adaptability for determining if a specific device can be a bridge device.
