METHOD AND NODES FOR HANDLING A GTP-U DIRECT TUNNEL

摘要

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).

1. A method in a Core Network, CN, node for handling a General packet radio service Tunnelling Protocol-User plane, GTP-U, tunnel, the method comprising:
when the GTP-U tunnel is to be set up, transmitting a first message to a Radio Access Network, RAN, gateway, which first message comprises a request for information identifying the RAN gateway; receiving a second message from the RAN gateway, which second message comprises the requested information identifying the RAN gateway; and determining a first endpoint node and a second endpoint node of the GTP-U tunnel, wherein the first endpoint node is the RAN node and the second endpoint node is the RAN gateway.
