Abstract
The invention relates to network nodes, a wireless communication device, WCD, and methods therein for handover. The method in the WCD comprises obtaining, from a source network node, information comprising at least part of a WCD Context related to the WCD. The method further comprises connecting to a target network node, and forwarding the obtained information to the target network node, enabling the target network node to derive the WCD Context based on the information.

1-33. (canceled)
A method for handover performed by a Wireless Communication Device (WCD) connected to a first network node, the method comprising:
- obtaining, from the first network node, information comprising at least part of a WCD Context related to the WCD;
- connecting to a second network node;
- and
- forwarding the obtained information to the second network node, enabling the second network node to derive the WCD Context based on the information.
A method for handover performed by a first network node connected to a Wireless Communication Device (WCD), the method comprising, when the WCD is to be handed over from the first network node to a second network node, providing information comprising at least part of a WCD Context to the WCD, for further transfer to the second network node, the WCD Context being related to the WCD.
A method for handover performed by a second network node, the method comprising:
- obtaining information comprising at least part of a Wireless Communication Device (WCD) Context from a WCD to be handed over from a first network node to the second network node, the WCD Context being related to the WCD;
- and
- deriving the WCD Context based on the obtained information.
A Wireless Communication Device (WCD) operable in a wireless communication network, the WCD being configured to:
- obtain, from a first network node when being connected to said first network node, information comprising at least part of a WCD Context related to the WCD;
- connect to a second network node;
- and
- forward the obtained information to the second network node, enabling the second network node to derive the WCD Context based on the information.
A first network node being configured to, when a Wireless Communication Device (WCD) connected to the first network node is to be handed over from the first network node to a second network node, provide information comprising at least part of a WCD Context to the WCD, for further transfer to the second network node, the WCD Context being related to the WCD.
A second network node, being configured to:
- obtain information comprising at least part of a Wireless Communication Device (WCD) Context from a WCD to be handed over from a first network node to the second network node, the WCD Context being related to the WCD;
- and
- derive the WCD Context based on the obtained information.
