A method for facilitating communication in a mobile communication system in which address-delegating entities are involved, wherein mobile nodes attaching to the communication system get assigned an address or address prefix, wherein the address or address prefix assignment is delegated from an entity being associated with mobility management&#x2014;mobility entity&#x2014;to some other configuration component (), is characterized in that the configuration component (), upon being delegated by a mobility entity to assign a mobile node an address or address prefix, stores information about the delegating mobility entity. Furthermore, a corresponding mobile communication system with discovery functionality of address-delegating entities is disclosed.

Method for facilitating communication in a mobile communication system and mobile communication system

A method for operating a mobile network, especially for charging traffic within the mobile network, wherein monitoring of chargeable events regarding traffic from and/or to a mobile node will be performed by a Charging Function for collecting charging data. The method is characterized in that a Charging Function's sub-function for monitoring of chargeable events on a data flow level or IP (Internet Protocol) flow level will be additionally located&#x2014;as an additional sub-function D-CEMF (Delegated Chargeable Event Monitoring Function)&#x2014;on at least one further network element, which is different from the Charging Function and which allows to traverse breakout and/or localized traffic of the mobile node, so that the Charging Function and the further network element each are including such a sub-function, and that the additional sub-function D-CEMF will report information regarding monitored chargeable events to the Charging Function. A mobile network for carrying out the method is described.

Method for operating a mobile network for charging traffic and corresponding mobile network

A radio network allows a flexible distribution of data flows between a mobile station and a mobility anchor of the network over different interfaces. Data flows are routed between at least one mobile station and a mobility anchor of the network. The mobile station can connect to the mobility anchor using multiple network interfaces simultaneously, the radio network including an application function capable of processing and/or analyzing information about routing policies contained in a signalling received from a mobile station, which is able to push or signal the processed and/or analyzed information from the application function to an entity that can enforce routing policies to forward the data flows to one or more selected interfaces and which is able to signal routing policies received from the network to the mobile station. Further, an according method for operating a radio network, especially for routing data flows within the network, is disclosed.
