Abstract:
A method of handling an overload situation of a Session Initiation Protocol, SIP, node in a telecommunication network, wherein the method includes the steps of receiving, by a proxy SIP node in the telecommunication network, an SIP request for requesting a service in the telecommunication network, forwarding, by the proxy SIP node, the SIP request to a service SIP node in the telecommunication network, receiving, by the proxy SIP node, from the service SIP node, a Server Failure Response message, wherein the Server Failure Response message includes an indication that the service node cannot fulfil the SIP request due to an overload situation at the service SIP node, and restricting, by the proxy SIP node, future SIP traffic to the service SIP node based on the received Server Failure Response message.
