Abstract:
1. A Core Network for data transmission in an Evolved Packet System (EPS), the Core Network comprising: 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); wherein 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; wherein the Interworking Function (IWF) is arranged such that, in view of a specific request from the signalling layer regarding a specific User Equipment (UE), wherein the specific User Equipment (UE) is related or potentially related to a plurality of nodes serving as at least one of the Home Location Register or the Home Subscriber Server (HSS), the specific request is multiplied by the Interworking Function (IWF) and sent to the plurality of nodes serving as at least one of the Home Location Register or the Home Subscriber Server (HSS); and wherein responses of the plurality of nodes serving as at least one of the Home Location Register or the Home Subscriber Server (HSS) are consolidated and the specific request answered to the signalling layer by a feedback communication.
