INTERWORKING FUNCTION BETWEEN IN AND HLR/HSS

摘要

A Core Network for data transmission in an Evolved Packet System (EPS) includes: one or more node(s) serving as a Home Location Register (HLR) according to a GSM/UMTS mobile communication network standard; a node serving as a Home Subscriber Server (HSS) according to 3GPP standards; and an Interworking Function (IWF) for the handling of messages exchanged between a signalling layer of the Core Network and the one or more node(s) serving as the Home Location Register (HLR) as well as the node serving as the Home Subscriber Server (HSS). The Core Network is arranged such that for an exchange of information between the signalling layer and the Interworking Function (IWF), an Intelligent Network (IN) or an Advanced Intelligent Network (AIN) is used.
