The MME includes a processing unit which translates the TAU request into a location area update (LAU) request. The MME includes a second network interface in communication with the processing unit which sends the LAU request to a mobile switching center (MSC) selected as a tracking MSC thereby establishing the MME as a network node through which the UE is paged. The second network interface receiving a LAU response from the tracking MSC that includes at least information identifying one or more suitable location area identifiers (LAI(s)) to which handover is allowed and Network Resource Identifier (NRI) information where the information indicates that the tracking MSC controls the suitable LAI(s), and the processing unit translating the LAU response into a TAU response which is sent through the first network interface to the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inter-domain coordination for MT and MO calls","description":"A mobility management entity (MME) for setting up a call includes a first network interface which receives a tracking area update (TAU) request from a user equipment (UE).
