The invention relates to a heterogeneous mobile radio system () for providing services from a packet data network for a mobile terminal (MT) (). Said system comprises at least one first mobile radio network () and one second mobile radio network (). Said mobile radio networks () respectively comprise at least one access node () to the packet data network, and the access node () of the second mobile radio network () can only be indirectly connected to the packet data network via the access nodes () of the first mobile radio network (). The invention also relates to a method for providing services from a packet data network for a mobile terminal () of a mobile radio system, said method comprising the following steps: (a) at least one first () and one second () mobile radio network respectively comprising at least one access node () to the packet data network are provided; and (b) the mobile radio networks () are combined in such a way that data packets can only be indirectly transported between the second mobile radio network () and the packet data network via the access nodes () of the first mobile radio network (). The invention further relates to a mobile terminal () for using a heterogeneous mobile radio system comprising at least one first mobile radio network () and one second mobile radio network (). Said mobile terminal () can simultaneously maintain connections to the first () and the second () mobile radio networks.
