Method for controlling access to a shared wireless medium or several connections

摘要

The invention concerns a method for admission control of connections made up of one or several flows to a shared wireless medium. It applies criteria for each new connection to determine whether resources can be provided for this connection. The criteria include the steps of: calculating a number (R) of retransmissions of frames which are needed, depending on: a target application PDU error rate (epsilon_i); a data link layer mean error rate (BER); and a maximum size (L) of the transmitted frames; calculating the achievable quality of service parameters (T'_i) based on the calculated number (R) of retransmissions with the target application PDU error rate (epsilon_i), and determining if resources can be provided for the connection depending on the achievable quality of service parameter (T'_i).
