Abstract: A method to reduce group reformation time and maintain seamless connectivity in a peer-to-peer network at the time of disappearance of the Group Owner (GO). Each of the nodes is provided with an emergency leader list which prioritizes a predetermined number of emergency leader nodes each of which is a client node having intent of acting as an emergency leader, wherein the emergency leader list is prepared right at the time of group formation. The emergency leader nodes broadcast beacons when a leader node disappears from the group without notice. Each of the client nodes barring a first-priority emergency leader node of the emergency leader list connects to a highest priority one of emergency leader nodes detected by the client node.

Abstract: A first communication terminal, unconnected with a communication network, searches for a second communication terminal existing around the own communication terminal. In the communication network, one of a plurality of communication terminals functions as a master having a function of an access point, and the rest of the communication terminals function as slaves of the master. Based on the information included in a communication message received from one or more second communication terminals found through the search, the first communication terminal determines a second communication terminal which serves as a connection counterpart from among the second communication terminals, and configures a communication network with the determined connection counterpart.
Abstract translation: 与通信网络未连接的第一通信终端搜索存在于自身通信终端周围的第二通信终端。 在通信网络中，多个通信终端之一用作具有接入点功能的主机，其余的通信终端用作主机的从机。 基于从通过搜索发现的一个或多个第二通信终端接收到的通信消息中包含的信息，第一通信终端确定用作第二通信终端中的连接对方的第二通信终端，并且配置通信网络 确定的连接对应。

In the communication network, one of communication terminals functions as a master having a function of an access point and the rest of the communication terminals function as slaves of the master. Among the one or more second communication terminals found through the search, the first communication terminal determines a second communication terminal, in which information included in a communication message received from the second communication terminal shows that it is a connected master terminal which is a terminal connected with the communication network and functions as the master, to be a connection counterpart. Then, the first communication terminal configures a network with the determined connection counterpart.

Abstract: Provided is a data sharing system in which data are shared between a plurality of communication terminals capable of wirelessly transmitting and receiving a communication message to and from each other. Each communication terminal determines whether or not the own communication terminal is a specified terminal. Each communication terminal, in case of it is determined that the own communication terminal is a specified terminal, transmits a holding list that lists information about data that the own communication terminal holds, to another communication terminal through use of a communication message. Each communication terminal, when receiving a holding list from another communication terminal, transmits and receives communication messages to and from the other communication terminal that is a source of the holding list that does not match the holding list of the own communication terminal so as to share data with each other.
Abstract translation: 提供了一种数据共享系统，其中在能够相互无线地发送和接收通信消息的多个通信终端之间共享数据。 每个通信终端确定自己的通信终端是否是指定的终端。 在确定自己的通信终端是指定终端的情况下，每个通信终端通过使用通信消息向另一个通信终端发送列出与自己的通信终端保持的关于数据的信息的保持列表。 每个通信终端在从另一个通信终端接收到保持列表时，向作为与本通信终端的保持列表不匹配的保持列表的源的其他通信终端发送和接收通信消息，以便共享 数据彼此。

Abstract: A communications terminal (a first communications terminal) that creates a holding list that lists information about remaining data, after the removal from data held by said communications terminal of at least one item of data which is not desired to be shared with another communications terminal (a second communications terminal), and sends said list to the second communications terminal by using a communications message. The second communications terminal determines what data, among the data in the holding list received from the first communications terminal, is not held by the second communications terminal, and sends a request for the determined data to the first communications terminal by using a communications message. The first communications terminal sends the data requested by the second communications terminal to the second communications terminal, by using a communications message.
