Patent number: 11057767Abstract: The embodiments herein relate to a method performed by a local subscriber node for handling attachment of a User Equipment (UE) to a central network. The local subscriber node comprises default subscription data which is common for all UEs which are associated with a local network. When a connection to a central subscriber node is accessible, the local subscriber node obtains 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, the local subscriber node sends the obtained authentication data for the UE to a mobility management node.Type: GrantFiled: October 11, 2016Date of Patent: July 6, 2021Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lasse Olsson, Qian Chen, Håkan Tranberg, Hanbing Zhang
