Push-to talk over Ad-Hoc networks
DCFirst Claim
1. A network system comprising a plurality of network nodes, wherein:
- a first plurality of network nodes comprises means for temporarily forming a first group with the first plurality of network nodes in communication with each other using sending means for sending information to the first group and receiving means for receiving information from the first group; and
a second plurality of network nodes comprises means for temporarily forming a second group with the second plurality of network nodes in communication with each other using sending means for sending information to the second group and receiving means for receiving information from the second group;
wherein a first network node is included in the first plurality of network nodes and the second plurality of network nodes and configured to provide communication between the first group and the second group;
wherein the sending means and the receiving means are configured to provide a direct contact via a radio connection between at least two network nodes of the first group and the second group.

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.

16. A method for controlling network system comprising:
-
temporarily forming a first group including a first plurality of network nodes, temporarily forming a second group including a second plurality of network nodes, sending and receiving information between the first group and the second group, wherein a first network node included in the first plurality of network nodes and the second plurality of network nodes sends and receives the information between the first group and the second group; wherein the information is sent and received using a direct contact via a radio connection between at least two network nodes of the first group and the second group. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
