Session continuity
First Claim
1. A method for supporting session continuity, the method comprising:
- providing a first interface in a communications device for transmitting data via an access network;
providing in the communications device a virtual interface corresponding to the first interface;
communicating via the access network using the first interface; and
sending data between the first interface and the virtual interface.

Abstract
Session continuity is supported by placing suitable functionality in a communications device and a communications system. In a communications device, a first interface is provided for transmitting data via an access network. A virtual interface corresponding to the first interface also is provided. Communications via the access network take place using the first interface and sending data between the first interface and the virtual interface. In a communications network, it is detected that a communications device is establishing communications via an access network. A network address used earlier by the communications device is determined, and the network address is retained when the communications device communicates via the access network.
