The invention relates to a heterogeneous mobile radio system ( 1 ) for providing services from a packet data network for a mobile terminal (MT) ( 7 ). Said system comprises at least one first mobile radio network ( 2 ) and one second mobile radio network ( 3 ). Said mobile radio networks ( 2, 3 ) respectively comprise at least one access node ( 4, 5 ) to the packet data network, and the access node ( 5 ) of the second mobile radio network ( 3 ) can only be indirectly connected to the packet data network via the access nodes ( 4 ) of the first mobile radio network ( 2 ). The invention also relates to a method for providing services from a packet data network for a mobile terminal ( 7 ) of a mobile radio system, said method comprising the following steps: (a) at least one first ( 2 ) and one second ( 3 ) mobile radio network respectively comprising at least one access node ( 4, 5 ) to the packet data network are provided; and (b) the mobile radio networks ( 2, 3 ) are combined in such a way that data packets can only be indirectly transported between the second mobile radio network ( 3 ) and the packet data network via the access nodes ( 4 ) of the first mobile radio network ( 2 ). The invention further relates to a mobile terminal ( 7 ) for using a heterogeneous mobile radio system comprising at least one first mobile radio network ( 2 ) and one second mobile radio network ( 3 ). Said mobile terminal ( 7 ) can simultaneously maintain connections to the first ( 2 ) and the second ( 3 ) mobile radio networks. |
