Abstract: With defining the overload control under the given situation, this paper analyzes the requirements for NGN overload control, and enhances the overload control architecture proposed in an ETSI TISPAN draft by adding SLA-based policy component.It facilities the development, deployment and management of services and makes services development quick, economical and effective in NGN. Four deployments about NGN overload control component are discussed, and the control procedure is given, as well as the information flow.
