摘要

The embodiments herein relate to a method performed by a mobility node (410) for managing network connections to a eu (101). eu (101) is simultaneously connected to a first gateway (408a) via a connection to a 3gpp network (401) and a connection to a non-3gpp network (115). mobility node 410 detects that eu 101 has moved to another location. mobility node 410 selects a second gateway 408b to which eu 101 is to be relocated. the second gateway 408b is closest to eu 101 at the other location. the mobility node (410) transmits relocation information to the first gateway (408a). relocation information indicates that a gateway relocation to the second gateway (408b) is required for eu (101). Gateway relocation involves disabling both the 3gpp (401) and non-3gpp (115) network connection.
