Fast combinational voice call continuity from lte to 2g/3g cs domain

A method comprising:

• handing over a session between a source network which provides a first connection type domain and a target network which provides the first connection type domain and a second connection type domain;
• and
• receiving, before performing a handover from the source network to the target network, a preferred transfer domain in the target network.

A network node comprising a processor, the processor being configured to:

• hand over a session between a source network which provides a first connection type domain and a target network which provides the first connection type domain and a second connection type domain;
• and
• receive, before performing a handover from the source network to the target network, a preferred transfer domain in the target network.

A network control element comprising a processor, the processor being configured to:

• handover over a session of a network node between a source network which provides a first connection type domain and a target network which provides the first connection type domain and a second connection type domain;
• and
• send a preferred transfer domain in the target network to a network node before the network node performs a handover from the source network to the target network.

A computer program product comprising at least one computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising:

• program code instructions for handing over a session between a source network which provides a first connection type domain and a target network which provides the first connection type domain and a second connection type domain;
• and
• program code instructions for receiving, before performing a handover from the source network to the target network, a preferred transfer domain in the target network
