Method of controlling congestion for contention access network
A method of controlling congestion in a communications network comprising a plurality of terminals, comprises the steps of: receiving a message or a message fragment at a given instant; evaluating the number of terminals currently sending; defining a congestion window, of duration Δtf configured so as to be proportional to the number n of terminals currently sending and inversely proportional to the maximum input loading g of the network which makes it possible to obtain a substantially zero rate of retransmissions; for each terminal and each message or message fragment to be sent, make the start of the congestion window coincide with the given instant of receipt of a message or message fragment and define an actual instant of sending of the message or message fragment as a random value taken in the congestion window.. .

Mobile communication method, policy and charging rule server apparatus, and mobile management node
When congestion is detected in an s-gw, communications are allowed to continue as many as possible. A mobile communication method according to the present invention includes: notifying, by the s-gw, a pdf in a pcrf of detection of congestion when the congest is detected; acquiring, by the pdf in the pcrf, charging system information regarding ues using an s1 bearer and an s5 bearer set in the s-gw from an hss; acquiring, by the pdf in the pcrf, communication service class information in a flow unit in the s1 bearer and the s5 bearer from the p-gw according to the notification; and performing, by the pdf in the pcrf, bandwidth adjustment on specific flows of the s1 bearer and the s5 bearer based on the charging system information and the communication service class information in the flow unit..
