ABSTRACT:
A communication system includes a radio access network (RAN) and a core packet network that allows registration of mobile devices. A temporary mobile device identifier (TMDI) assigned to the mobile device includes, at least in part, an address of a mobility control function (MCF) currently serving the mobile device. Components in the system use the TMDI to direct messages to the appropriate MCF.
