FORCED INTERSYSTEM HANDOVER IN CASE OF MME GATEWAY FAILURE

摘要

A system comprising an inter-RAT/inter-network redundancy controller (IRC) is provided. The IRC is configured to communicate with a source gateway in communication with a source radio access network (RAN) using a first radio access technology (RAT). The IRC is further configured to communicate with a target gateway in communication with a target RAN using a second RAT. The IRC is further configured to promote a handover of a user equipment from the source RAN connected to the source gateway to the target RAN connected to the target gateway when the source gateway fails.
