Abstract:
A method of suppressing overload of a first node in a telecommunications network by the steps of a second node:receiving a signal indicating that a call directed from the second node to the first node has been rejected and in response restricting the rate of transmission of calls from the second node to the first node to a predetermined level, and monitoring duration through a predetermined time period wherein if a further signal indicating at a call directed from the second node to the first node has been rejected is receive during the predetermined time period, the rate of transmission of calls from the second node to the first is restricted further to a further reduced predetermined level and duration through a further predetermined period is monitored, in which the steps of restricting and monitoring are repeated until no signal indicating that a call directed from the second node to the first node has been rejected is received during the latest predetermined period, in which if no signals indicating that a call directed from the second node to the first node has been rejected is received during the latest predetermined period a reduced level of restriction is applied, and duration through a further predetermined period is monitored, in which the level of restriction is reduced by increasing allowed call rate by a predetermined factor in the range 1.01 to 1.07.
