Abstract
SMS services are provided to roaming mobile devices at visiting networks. This invention implements interworking between VoLTE and circuit-switched (CS) SMS and handles roaming towards both the VPLMN (visited public land mobile network) and HPLMN (home public land mobile network). The interworking function translates CS signals from the VPLMN into IMS signals for the IMS core at the HPLMN and performs location-update registration at the HSS at the HPLMN to exchange SMS communications.
