First Claim
1. A method of acquiring a remote node that is not yet acquired by a hub in a satellite communication network, said method comprising steps of:
- sending a first acquisition command from the hub to the remote node that is not yet acquired to acquire the remote node to be added to the network, said first acquisition commandinstructing the remote node to send an acquisition response, and including a first frequency;
sending a first acquisition response based on the first acquisition command from the remote node to the hub using the first frequency;
sending a second acquisition command from the hub before receiving the first acquisition response at the hub;
selecting a next acquisition remote node according to at least one of a round robin algorithm, a least recently used algorithm, and a priority algorithm; and
selecting a next frequency based on an offset frequency of a previous acquisition command,wherein the second acquisition command identifies the next acquisition remote node for acquisition and includes the next frequency.

Abstract
A method of acquiring a remote node in a communication network includes sending a first acquisition command from a hub to the remote that instructs the remote to send an acquisition response and includes a first frequency (S100). The method also includes sending a first acquisition response based on the first acquisition command from the remote to the hub using the first frequency (S106) and sending a second acquisition command from the hub before receiving the first acquisition response at the hub (S102). A related method of acquiring a remote node in a synchronous communication network and a related hub apparatus, remote apparatus, computer program product and system each include similar features.

7. A method of acquiring a remote node that is not yet acquired by a hub in a synchronous satellite communication network, said method comprising steps of:
-
transmitting a sequence of downlink messages from the hub to the remote node that is not yet acquired with a common time interval between the start of each downlink message, said common time interval being less than twice a time elapsed between sending one of the downlink messages from the hub and receiving the one of the downlink messages at the remote node, wherein a first downlink message in the sequence includes a first acquisition command to acquire the remote node to be added to the network and cause the remote node to transmit a first acquisition response, and a second downlink message immediately following the first downlink message in the sequence of downlink messages includes a second acquisition command for the remote node to transmit a second acquisition response; and receiving the first acquisition response to the first downlink message at the hub after sending the second downlink message from the hub. - View Dependent Claims (8, 9, 10)
