摘要： As multicast services become prevalent, it is important to find viable solutions for multicasting to mobile nodes. This problem is complicated by the necessity to support multicast services over existing backbone and access networks that may have varying network and/or link layer multicasting capabilities. While most work on supporting multicast services focuses on the IP layer solution, the present invention presents an application-layer approach for providing multicast services to mobile users traversing networks with diverse multicast capabilities. The present invention places multicast proxies in the backbone and access networks to support several multicast-related functions at the application layer including the creation of virtual networks for dynamically tunneling through non-multicast-capable networks.

摘要： There is provided a technique of establishing a communication between a transmitting node and a receiving node by selecting a suitable frequency band for communication without using a predetermined control channel. Firstly, a frequency band to be used as a control channel is selected from among low frequency bands, and information on frequencies and information on application's quality requirements are exchanged between the transmitting node and the receiving node using the control channel. Then, a frequency band to be used as a data channel is determined, and a communication is started. During the communication, frequency use statuses around the transmitting node and the receiving node are notified through the control channel, and when the control channel or data channel being used becomes unusable, the channel is dynamically changed. Since a low frequency band having a long propagation distance is used as the control channel, exchange of information through the control channel can be performed before communication through a data channel in a high frequency band becomes possible, the data channel that meets the quality requirements can be determined quickly.
摘要翻译：提供了通过在不使用预定控制信道的情况下选择用于通信的合适频带来建立发送节点和接收节点之间的通信的技术。首先，从低频带中选择要用作控制信道的频带，并且使用控制信道在发送节点和接收节点之间交换关于频率的信息和应用的质量要求的信息。然后，确定要用作数据信道的频带，并开始通信。在通信期间，通过控制信道通知发送节点和接收节点周围的频率使用状态，当使用的控制信道或数据信道变得不可用时，信道被动态地改变。由于使用具有较长传播距离的低频带作为控制信道，所以可以在通过高频带中的数据信道进行通信之前通过控制信道进行信息交换，满足质量要求的数据信道可以迅速确定

摘要： Provided is a technique that enables quicker detection of usable frequency bands in a cognitive radio system. Each radio communication apparatus in the system has, in common, a hash function used to obtain a frequency range from time information and location information. Each radio communication apparatus detects unused frequency bands while narrowing down a frequency range over which a detection process is performed by obtaining the terminal's own location information and current time information from GPS signals, and input them to the hash function. Since a transmitting node and a receiving node that perform a communication are at locations close to each other at the same time, they perform detection in the same frequency range. Therefore, an unused frequency band(s) that is usable by both of them can be detected. Furthermore, at different locations or at different times, the detection will be performed in different frequency ranges. Therefore efficient frequency utilization can be achieved. It is preferred that the nodes have a plurality of kinds of hash functions in common.
摘要翻译：提供了一种能够更快地检测认知无线电系统中的可用频带的技术。系统中的每个无线电通信装置通常具有用于从时间信息和位置信息获得频率范围的散列函数。每个无线电通信装置通过从GPS信号获得终端自己的位置信息和当前时间信息，同时缩小执行检测处理的频率范围，并将其输入到散列函数来检测未使用的频带。由于执行通信的发送节点和接收节点同时处于彼此靠近的位置，所以它们在相同的频率范围内进行检测。因此，可以检测到两者都可使用的未使用的频带。此外，在不同的位置或不同的时间，检测将在不同的频率范围内执行。因此，可以实现高效的频率利用。优选地，节点具有共同的多种散列函数。
