Abstract

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). 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.
