Abstract

A method performed by a source network node for handover of a wireless communication device in a first wireless communications network using a first RAT is provided. The handover is to be performed from the source network node to a target network node. The wireless communication device is configured to communicate with the source network node directly and to communicate with the source network node via a radio access node in a second wireless communications network using a second RAT. The source network node provides () the target network node with information about parameters relating to a communication between the wireless communication device and the source network node via the radio access node. The source network node receives () a feedback from the target network node. The feedback comprises an indication of whether or not the radio access node was able to keep a context of the wireless communication device in the second wireless communications network. The context comprises an identity of the wireless communication device in the second wireless communications network, and information required to interact with the wireless device in the second wireless communications network.
