A communication system is described in which a mobile communication device receives MDT configuration requests from a base station or radio network controller to initiate an MDT measurement session for obtaining measurement data and location related data for identifying a location to which said measurement data relates. The mobile communication device checks a user consent indicator in memory and only provides the location related data if the user consent indicator indicates that a user of the mobile communication device consents to the provision the location related data.

Network entity, communication device, mobile communication device and method thereof

A method for measuring network operation related parameters in a mobile communication network with a core network and a radio-access network, preferably in form of a LTE- or UMTS-network, includes the steps of a) configuring an entity in the mobile communication network for measuring including network operation related parameters to be measured, b) selecting a measuring entity, c) measuring the network operation related parameters by the measuring entity, and d) analyzing the measured parameters wherein a filtering is performed prior to step d), wherein the filtering is performed on an entity in the radio access network of the mobile communication network and wherein the filtering reduces the amount of data of the measured network operation related parameters for step d). A system for measuring network operation related parameters is also described.

A method for supporting congestion management in a congestion exposure-enabled network, wherein sending hosts and receiving hosts communicate with each other by sending flows of packets over network paths via intermediate routers, which, upon detecting congestion, mark packets of the flows as congestion packets by including congestion information, wherein congestion is indicated to the sending hosts via a congestion feedback mechanism, and wherein the sending hosts, upon receiving congestion indications, declare a subset of the packets they send as congestion response packets by including congestion information, depending on whether the amount of congestion response packets is balanced with the indicated congestion level or not is characterized in that aggregated congestion is determined on the basis of congestion information included in packets that are sent over the network paths between the sending hosts and the receiving hosts. Furthermore, a corresponding congestion exposure-enabled network system and a corresponding intermediate router are disclosed.
