1. A method, comprising:
- establishing a logical connection between a terminal and a node of a first network to communicate between the terminal and the first network, the logical connection being used to provide services to the terminal from at least the first network and a second network,wherein first network services and second network services are provided in parallel in the logical connection,wherein the logical connection is a context and two internet protocol addresses, one for an internet protocol address of the first network and another for an internet protocol address of the second network, that are provided in the context, wherein when an uplink packet is received by the node in the first network, the node checks if the packet is for the first or the second network and, if the packet is for the second network, forwarding the packet to the second network.

Abstract
The invention provides a method, system and devices for providing a connection of a terminal to at least two networks for providing services to the terminal. The terminal establishes only one logical connection to a support node of a network for communication between the terminal and the network. The logical connection is used for providing services to the terminal from the at least two networks. A network visited by the terminal provides visited services in addition to home services provided to the terminal from a home network of the terminal, the services being provided in parallel.

9. An apparatus, comprising:
-
means for establishing a logical connection to a node of a first network for communication between a terminal and the first network, the logical connection being used for providing services to the terminal from at least the first network and a second network, wherein first network services and second network services are provided in parallel in the logical connection, wherein the logical connection is a context and two internet protocol addresses, one for an internet protocol address of the first network and another for an internet protocol address of the second network, are provided in the context, wherein when an uplink packet is received by the node in the first network, the node checks if the packet is for the first or the second network and, if the packet is for the second network, forwarding the packet to the second network.

14. A method, comprising:
-
establishing, by a processor, a logical connection between a terminal and a node of a home network to communicate between the terminal and the home network, the logical connection being used to provide services to the terminal from at least the home network and a visited network, wherein home network services and visited network services are provided in parallel in the logical connection, wherein the logical connection is a context and two internet protocol addresses, one for a visited internet protocol address and one for a home internet protocol address, are provided in the context, wherein when an uplink packet is received by the node in the first network, the node checks if the packet is for the home or the visited network and, if the packet is for the visited network, forwarding the packet to the second network. - View Dependent Claims (15, 16)
