  • Method and nodes for handling a GTP-U direct tunnel
    Patent number: 10306685
    Abstract: The embodiments herein relate to a method in a CN node (303) 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 (305). The first message comprises a request for information identifying the RAN gateway (305). The CN node (303) receives a second message from the RAN gateway (305). The second message comprises the requested information identifying the RAN gateway (305). The CN node (303) determines a first endpoint node and a second endpoint node of the GTP-U tunnel. The first endpoint node is the RAN node (301) and the second endpoint node is the RAN gateway (305).
