CORE NETWORK BECOMING AWARE OF PLMNS WITH DISASTER CONDITIONS

摘要

Systems and methods for enabling User Equipments (UEs) to use a Public Land Mobile Network (PLMN) failing service under disaster conditions and to receive services from alternative PLMNs. In some embodiments, a method performed by a first network node comprises receiving, from a second network node, a first disaster roaming PLMN list. The method also comprises determining that a UE is to be authenticated. The method further comprises providing, to a third network node, a request including the disaster roaming PLMN list, responsive to determining that the UE is to be authenticated. In this way, an interruption of the service at the UE is minimized in case of the disaster conditions.
