Method for allowing a successful first mobile terminated call towards a mobile subscriber initially assigned to a failing core network node

摘要

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.

1. A method for a fallback core network node within a pool of core network nodes for allowing a successful first mobile terminated call towards a mobile subscriber initially assigned to a failing core network node, the method comprising the steps of:
receiving, via a receiver circuit, data associated to International Mobile Subscriber Identity and Location Area Identifier of a mobile subscriber handled in the failing core network node, receiving, via the receiver circuit, a service request from a home location register, determining, via a processor circuit, that the service request indicates that the fallback core network node is acting as a fallback core network node for the failing core network node, sending, via a transmitter circuit, a response to the service request towards the home location register comprising a roaming Number assigned by the fallback core network node, initiating, via the processor circuit, of paging request towards the radio network comprising said received Location Area Identifier of said mobile subscriber, and sending, via the transmitter circuit, a Service Request towards the home location register comprising a Mobile Station Integrated Services Digital Network Number of the mobile subscriber.
