Abstract
The embodiments herein relate to a method in a CN node () for handling a GTP-U tunnel. When the GTP-U tunnel is to be set up, the CN node transmits a first message to a RAN gateway (). The first message comprises a request for information identifying the RAN gateway (). The CN node () receives a second message from the RAN gateway (). The second message comprises the requested information identifying the RAN gateway (). The CN node () determines a first endpoint node and a second endpoint node of the GTP-U tunnel. The first endpoint node is the RAN node () and the second endpoint node is the RAN gateway ().
