Abstract: The present invention addresses apparatuses, methods and computer program product for providing user location in network interworking (a mobile device accessing a 3GPP network through a broadband fixed network, a.k.a. UMA, WLan femto-Cell). When the policy and charging rules function PCRF contacts broadband network policy function BPCF after the IP-CAN session establishment for setting up an S9a control session between BPCF and PCRF, the BPCF uses the tunnel information, i.e. the IP tunnel address received from PCRF, to retrieve the line identifier of the subscriber line corresponding to the IP tunnel address of the DSLAM end of the tunnel, i.e. the IP address allocated earlier by the fixed broadband access network to the fixed network user/UE, and sends the line identifier to PCRF. Then, the PCRF sends the line identifier, accompanied with relevant 3GPP user/UE identification, to P-CSCF and possibly to other network elements that may need the user location information, e.g. to PCEF/PGW/GGSN.

Abstract: The present invention provides methods, apparatuses and computer program product relating to user plane congestion control. The present invention includes receiving, at a network entity, an indication that there is a congestion in at least one network element in a network, receiving, at the network entity, information indicating an internet protocol address of at least one user equipment located in the congested network, and preventing, by the network entity, a setup and/or continuation of at least one application of the at least one user equipment using the at least one network element in the network if it is determined that there is a congestion in the network.
