First Claim
Patent Images
1. - A method of protecting payload information in radio transmission comprising the steps of:
- dividing the payload into a plurality of data portions,grouping a data portion so as to form a packet,selecting an available radio channel, suitable for incorporating said packet in said radio channel,incorporating at least one packet in the selected radio channeltransmitting, said selected radio channel with said at least one packet incorporated in the radio channelwherein the step of grouping a data portion so as to form a packet comprises the steps of;
identifying data portions according to a criterion of protection selected from a plurality of criteria of protection,grouping data portions identified as having the same criterion in a packet,labeling said packet containing data portions with the same criterion said labeling being indicative of a priority level for the packet, andwherein the step of incorporating at least one packet in the selected radio channel is performed such that the packets are incorporated in the selected channel according to said priority level.

Abstract
System and method for improving the protecting radio channels in transmission, according to which the payload information of the signal to be transmitted is divided into a plurality of data portions of smaller size which are then grouped into packets and the packets are labeled based on a criterion from among a plurality of criteria, said criterion being indicative of a level of priority associated to said packets. The packets are subsequently radio transmitted in accordance with their level of priority indicated by their associated label.
