| 1. A method of facilitating communications between one or more of a plurality of communication devices of an asynchronous
network, comprising:
determining a first communication schedule of a first communication device of the plurality of communication devices and a
second communication schedule of one or more of the plurality of communication devices;
a mediation device of the asynchronous network establishing a common synchronization schedule from the first and second communication
schedules, further comprising:
the mediation device transmitting a synchronization message to the plurality of communication devices when the mediation device
knows the plurality of communication devices will be able to receive the synchronization message; and
the mediation device transmitting the common synchronization schedule to the plurality of communication devices in accordance
with the synchronization message,
wherein the common synchronization schedule provides information needed by the first and second communication devices to be
available to receive messages sent to them via the mediation device; and
upon receiving a communication request from the first communication device, the mediation device initiating transmittal of
and transmitting a message received from the first communication device of the plurality of communication devices to the one
or more of the plurality of communication devices when the one or more of the plurality of communication devices are available
to receive the message in accordance with the common synchronization schedule.
