Abstract
The invention proposes a network system comprising a plurality of network nodes (10, 11), each of the network nodes comprising means (103, 113) for temporarily forming a group with at least one of the plurality of network nodes, sending means (101, 111) for sending information (which may include voice, text message, images etc.) to the group and receiving means (102, 112) for receiving information from the group, wherein the sending means and the receiving means are configured to provide a direct contact via a radio connection (12) between at least two network nodes of the group. The invention also proposes a corresponding method, a corresponding network node and network control nodes for assisting in forming temporary groups.
