摘要
The embodiments herein relate to a method performed by a mobility node for handling a UE which has moved from an old to a new location. The mobility node retrieves UE context from a database. The mobility node determines whether there is a change of mobility node and first gateway at the new location. When there is a change of the first gateway, the mobility node initiates setup of a tunnel between a second gateway and a new first gateway. When there is a change of the mobility node, the mobility node provides a subscriber server with UE context for a new mobility node at the new location. The mobility node transmits updated UE context to the database.
