Abstract
A method for a fallback core network node within core network nodes for a first mobile terminated call towards a mobile subscriber initially assigned to a failing ore network node (failing CNN). The method includes receiving data associated to International Mobile Subscriber Identity and Location Area Identifier (LAI) of a mobile subscriber handled in the failing CNN. The method includes receiving a service request from a home location register (HLR), whereby the service request indicates that the fallback CNN is acting as a fallback CNN for the failing CNN, and sending a response to the service request towards the HLR comprising the roaming Number assigned by the fallback CNN. The method includes initiating a paging request towards the radio network comprising said received LAI of said mobile subscriber, and sending a Service Request towards the HLR comprising the Mobile Station Integrated Services Digital Network Number of the mobile subscriber.
