Method and apparatus for route discovery within a communication system
First Claim
Patent Images
1. A method for route discovery between a source node and a destination node within an ad-hoc communication system, the method comprising:
- receiving a route discovery request from the source node;
locating a source base station and a destination base station serving the source node and the destination node;
determining intervening base stations between the source and the destination base stations;
instructing intervening nodes in communication with the intervening base stations to participate in route discovery;
receiving, by a node, a notification message instructing the node to participate in route discovery, wherein the notification message comprises a first session identification;
receiving a route-discovery message comprising a second session identification;
determining if the first session identification matches the second session identification; and
forwarding the route-discovery message based on whether the first session identification matches the second session identification.

Abstract
A communication system (100) is provided that comprises an overlay communication system and an underlay ad-hoc communication system. Route discovery in the ad-hoc communication system takes place by notifying the overlay communication system of the source and destination nodes. The overlay communication system instructs all base stations between the source and destination nodes to instruct all nodes to participate in route discovery.

1. A method for route discovery between a source node and a destination node within an ad-hoc communication system, the method comprising:
-
receiving a route discovery request from the source node; locating a source base station and a destination base station serving the source node and the destination node; determining intervening base stations between the source and the destination base stations; instructing intervening nodes in communication with the intervening base stations to participate in route discovery; receiving, by a node, a notification message instructing the node to participate in route discovery, wherein the notification message comprises a first session identification; receiving a route-discovery message comprising a second session identification; determining if the first session identification matches the second session identification; and forwarding the route-discovery message based on whether the first session identification matches the second session identification. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. An apparatus comprising:
-
a receiver adapted to receive a route discovery request from a node in an ad-hoc communication system to communicate with a destination node within the ad-hoc communication system; logic circuitry adapted to locate a source and the destination node and adapted to determine intervening base stations between the source and the destination node; a transmitter adapted to transmit instructions instructing intervening nodes in communication with the intervening base stations to participate in route discovery; a second receiver adapted to receive a notification message instructing a node to participate in route discovery, wherein the notification message comprises a first session identification, and wherein the second receiver is further adapted to receive a route-discovery message comprising a second session identification; additional logic circuitry adapted to determine if the first session identification matches the second session identification; and a second transmitter adapted to forward the route-discovery message based on whether the first session identification matches the second session identification.
