Radio frequency/satellite/LAN random access several user separated source having access protocol followed using temporary resource access random variable and setting new random variable when confirmation not received.

摘要

The random user access to resources follows a protocol and has the user carrying out a periodic test (701) for transmission. A random variable with a temporary field resource access (702) is selected. Following compatibility verification (703), the user transmits digital packets. Where reception is confirmed, the system returns to the rest state (706). Otherwise, a modified random variable is selected (712) and the packets retransmitted.
