1. A method performed by a local subscriber node for handling attachment of a User Equipment (UE) to a central network, wherein the local subscriber node comprises default subscription data which is common for all UEs which are associated with a local network, the method comprising:
when a connection to a central subscriber node is accessible, obtaining authentication data associated with the default subscription data from the central subscriber node;
when the UE requests attachment to the central network when the connection to the central subscriber node is inaccessible, sending the obtained authentication data for the UE to a mobility management node.
