    • This invention concerns a network comprising a master and slaves. In the network, each slave figures out its performance values as performance parameters and transmits the performance parameters to the master. The master performs a process of selecting a backup master as a candidate for the next master, on the basis of the performance parameters transmitted from the slaves. The master supplies BM information containing synchronization information and the address of the backup master selected, to the slaves. When the master is removed from the network, the slaves determine the next master in accordance with the backup-master information. Thus, the slaves can be immediately connected to the next master.
    • 本发明涉及包括主机和从机的网络。 在网络中,每个从属设备的性能值作为性能参数,将性能参数传送给主站。 主机基于从从站发送的性能参数,执行选择备份主站作为下一个主站的候选者的过程。 主机向从站提供包含同步信息和所选备份主站的地址的BM信息。 当主机从网络中删除时,从站根据备份主控信息确定下一个主站。 因此,从站可以立即连接到下一个主站。

    • The present invention relates to a communication system, a communication method, an information processing apparatus, and an information processing method for easily and quickly organizing a communication group containing a plurality of apparatuses. The user places a PDA 2 in proximity to a personal computer 1. When an electromagnetic wave emitted from a reader/writer of the PDA 2 is received by a reader/writer of the personal computer 1, the personal computer 1 notifies the PDA 2 of stored communication group organizing information. The PDA 2 stores the communication group organizing information while establishing a synchronization for a Bluetooth communication with the personal computer 1 based on the communication group organizing information to establish the Bluetooth communication with the personal computer 1. The present invention is applicable to a variety of information processing apparatuses such as a personal computer and a PDA.
    • 通信系统,通信方法,信息处理装置和信息处理方法技术领域本发明涉及用于容易且快速地组织包含多个装置的通信组的通信系统,通信方法,信息处理装置和信息处理方法。 用户将PDA 2放置在个人计算机1附近。当从PDA 2的读取器/写入器发射的电磁波被个人计算机1的读写器接收时,个人计算机1向PDA 2通知 存储通信组织组织信息。 PDA 2存储通信组组织信息,同时基于通信组组织信息建立与个人计算机1的蓝牙通信的同步,以建立与个人计算机1的蓝牙通信。本发明可应用于各种信息 诸如个人计算机和PDA的处理设备。
