Flexible inter-network communication scheduling
First Claim
1. A method for coordinating inter-network communications between at least two networks, comprising the step of:
- providing a specific mode or sub-mode that defines the behavior of a node common to said at least two networks as being a node shared by said at least two networks.

Abstract
Systems and methods are provided for managing communications between two or more ad-hoc networks in a communication system. The systems and methods may have flexible communication time sharing of one or more nodes taking part in two or more ad-hoc networks. For example, the communication scheduling function for a node shared by two or more ad-hoc networks is provided with a generic functional architecture such that it may be located in a number of different locations. In one embodiment, a Bluetooth communication system includes an inter-piconet scheduling function having a JUMP mode introduced to distinctly identify a node to its neighbors as being shared with multiple ad-hoc networks. The jump mode may have one or more methods for managing the inter-network communications that may include: (1) predetermined fixed starting point and length communication windows, (2) time points with flexible starting points and communication window length, and/or (3) random starting time and length communication windows.

27. In an ad-hoc network comprising a first node which is a participant in a first network and a second network, a method comprising the steps of:
-
exchanging meeting information between the first node and another node of the first network, wherein the meeting information includes an indication of a time slot;
participating, by the first node, in the second network; and
participating, by the first node, in the first network, wherein the first node participates in the first network during a time period at, earlier than, or later than the time slot. - View Dependent Claims (28, 29, 30, 31)

32. In an ad-hoc network comprising a first node which is a participant in a first network and a second network, a method comprising the steps of:
-
exchanging meeting information between the first node and another node of the first network, wherein the meeting information includes an indication of a time point;
participating, by the first node, in the second network; and
participating, by the first node, in the first network, wherein the first node participates in the first network during a time period at, earlier than, or later than the time point, wherein the first node can participate in only one network at a time.

33. In an ad-hoc network comprising a first node which is a participant in a first network and a second network, a method comprising the steps of:
-
exchanging meeting information between the first node and another node of the first network, wherein the meeting information includes an indication of a time slot;
participating, by the first node, in the second network;
participating, by the first node, in the first network, wherein the first node participates in the first network during a time period earlier or later than the time slot; and
exchanging meeting information between the first node and another node of the second network, wherein the meeting information includes an indication of another time slot, wherein the first node participates with the second network during a time period earlier or later than the another time slot. - View Dependent Claims (34, 35)
