Method and device for establishing communication links and providing reliable confirm messages in a communication system
First Claim
1. A wireless communication network comprising:
- a plurality of mobile nodes for communicating over successive time frames each comprising a plurality of respective time slots of a same type, each mobile node comprising a transceiver, a directional antenna connected to said transceiver, and a controller connected to said transceiver and comprising a first time slot unit to schedule at least one respective time slot as a dedicated semi-permanent time slot for said mobile node to establish a communication link with each neighboring mobile node over a plurality of consecutive time frames, and while leaving at least one other time slot as an available time slot in each time frame, a second time slot unit to schedule the at least one available time slot to also serve the communication link with a neighboring mobile node based upon link communications demand, and an antenna aiming unit to aim said directional antenna toward each neighboring mobile node during communication therewith, each communication link being formed by an initiating mobile node and a receiving mobile node, the initiating mobile node transmitting a request for time slots to the receiving mobile node, the receiving mobile node transmitting a reply to the initiating mobile node, the initiating mobile node transmitting a confirmation to the receiving mobile node, and the receiving mobile node transmits the reply again if the confirmation is not received.

Abstract
A wireless communication network includes a plurality of mobile nodes each including a transceiver, a phased array antenna connected to the transceiver, and a controller connected to the transceiver. The controller schedules time slots for each time frame to establish a communication link with each neighboring mobile node. An initiating mobile node transmits a request for time slots to the receiving mobile node, which transmits a reply to the initiating mobile node. The initiating mobile node transmits a confirmation to the receiving mobile node, and the receiving mobile node transmits the reply again if the confirmation is not received. Alternatively, the receiving mobile node may transmit an acknowledgment to the initiating mobile node, and the initiating mobile node transmits the confirmation again if the acknowledgment is not received.

17. A method for establishing communication links for a plurality of mobile nodes over successive time frames each comprising a plurality of respective time slots of a same type, each mobile node comprising a transceiver, a directional antenna connected to the transceiver, and a controller connected to the transceiver, the method comprising for each mobile node:
-
scheduling at least one respective time slot as a dedicated semi-permanent time slot for the mobile node to establish a communication link with a neighboring mobile node over a plurality of consecutive time frames, and while leaving at least one other time slot as an available time slot in each time frame;
scheduling the at least one available time slot to also serve the communication link with a neighboring mobile node based upon link communications demand; and
aiming the directional antenna toward each neighboring mobile node during communication therewith;
each communication link being formed by an initiating mobile node and a receiving mobile node, the initiating mobile node transmitting a request for time slots to the receiving mobile node, the receiving mobile node transmitting a reply to the initiating mobile node upon receiving the request, the initiating mobile node transmitting a confirmation to the receiving mobile node upon receiving the reply, and the receiving mobile node transmitting the reply again if the confirmation is not received. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
