Abstract: A communication method, a communication system, a wireless terminal, and a wireless control method are provided that make it possible to share information between terminals without forming a group. In a communication method in a wireless communication network including a plurality of terminals (N1 to N3), a first terminal (N1) and a second terminal(N2 or N3) that belong to different groups, or do not belong to a group, can embed arbitrary information in a control frame (101) that is sent and received to search for a terminal or another group in vicinity, and notification information (MSG) of one of the terminals is notified to the other terminal by using the control frame.

Abstract: A communication terminal has a wireless communication part and a control part. The control part sequentially switches a plurality of communication channels and discovers another communication terminal existing around the communication terminal itself. In the case of connecting to the other communication terminal found in the discovery, the control part determines which of the communication terminals transmits a connection request. In a case where the communication terminal itself does not transmit a connection request, the control part stops the discovery process and waists for reception of a connection request from the other communication terminal by using a given communication channel.
Abstract translation: 通信终端具有无线通信部和控制部。 控制部顺序地切换多个通信信道，并且发现存在于通信终端本身周围的另一通信终端。 在与发现中发现的其他通信终端连接的情况下，控制部分确定哪个通信终端发送连接请求。 在通信终端本身不发送连接请求的情况下，控制部分通过使用给定的通信信道来停止发现处理并且阻止从另一个通信终端接收连接请求。

Abstract: A mechanism by which the number of groups can be reduced in a multi-group P2P network is disclosed. A method for group formation in wireless peer-to-peer (P2P) networks, includes: exchanging group-related information between group owners of neighboring P2P groups; deciding on whether a combined group of the neighboring P2P groups meets a predetermined condition of either of the neighboring P2P groups, based on the group-related information of the neighboring P2P groups; and merging the neighboring P2P groups to form at least one single group when the combined group meets the predetermined condition.

Abstract: A connection method in a wireless peer-to-peer group of nodes, wherein one of the nodes acts as a leader and others act as clients of the group, includes the steps of: sending credential information required for creating a virtual persistent group configuration from the leader to each of the clients; creating a virtual persistent group configuration at each of the clients which has received the credential information from the leader; and when leadership of the leader disappears, establishing a first-time connection between a first client and a second client based on persistent mechanism by invitation using the virtual persistent group configuration.

Abstract: A method includes: performing a scan to discover at least one Peer to Peer (P2P) group; sharing a result of the scan within a first P2P group; preparing a switching schedule of the first P2P group based on the shared result; wherein the switching schedule enables a switching device to disconnect from a first owner device in the first P2P group and to connect with a second owner device in a second P2P group; sharing an information with the second P2P group by using the switching device; and performing communication among the first P2P group and the second P2P group on the basis of the information.

Abstract: A wireless communication network includes a plurality of nodes each capable of performing wireless communication by a first communication method that can form P2P group and wireless communication by a second communication method. A first owner node that operates as an access point to a first P2P group uses the wireless communication by the second communication method to discover a second P2P group present in a second communicable range that is a region outside a first communicable range defined by the first communication method, predicts the time that elapses before the second P2P group moves into the first communicable range, and performs group reorganization before the predicted time elapses.
