Method of maximizing use of bandwidth for communicating with mobile platforms
First Claim
1. A method of maximizing bandwidth use in communications between a base station and a plurality of mobile platforms, the method comprising the steps of:
- using a broadcast transmission scheme to transmit data periodically to the plurality of mobile platforms;
determining the number of mobile platforms that have received the broadcast data in a predetermined time period; and
using a unicast transmission scheme to transmit the data to each of the mobile platforms that have not received the data after a predetermined number of the mobile platforms have been determined to have received the data in the predetermined time period.

Abstract
A system and method for switching between transmission modes provides more efficient use of available bandwidth. A content delivery system determines, based upon a predetermined limit, whether to broadcast content to a plurality of mobile platforms or unicast the data content via a point-to-point communication link. Acknowledgment signals from the mobile platforms are used to determine if the predetermined limit has been exceeded. A specific number or percentage defines the predetermined limit within a specified time period. The number of acknowledgment signals received is compared to the limit to determine if an exceedance condition has occurred.

8. A method of transmitting data to a plurality of mobile platforms to maximize the use of available bandwidth using a communication system having a base station and at least one satellite for transmitting the data to plurality of mobile platforms, the method comprising the steps of:
-
broadcasting data to a plurality of mobile platforms;
receiving confirmation from the mobile platforms that have received the data;
determining the number of mobile platforms that have received the data in a predetermined time period based upon the confirmations; and
transmitting the data using a point-to-point connection to the mobile platforms not providing confirmation after a predetermined number of mobile platforms have been determined to have received the data in the predetermined time period. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
