Abstract
A packet data core network node and methods supporting packet data communication are disclosed. In one embodiment, a packet date core network node in a first core network comprises a first communication mechanism for control plane handling and mobility management, a second communication mechanism for user plane management and a mechanism for communication with a dual mode mobile terminal over a first radio network. The packet data core network node comprises or communicates with a mapping function for mapping between first radio bearers used in the first core and radio networks and second radio bearers of a type different from the type of the first radio bearers and used in a second core radio network at handover of a dual mode mobile terminal from the first core network to the second core network or vice versa. Another embodiment is a dual mode mobile terminal including such mapping function.
