Abstract

A system and method are provided for processing packet mobile-terminated calls from an Internet host to a mobile terminal in a radio packet service network. The system may include a DNS for processing a domain name conversion request from the Internet host, and a mobile-terminated server for retrieving information of a packet mobile-terminated subscriber by searching for dynamic subscriber information in a conversion DB. The mobile-terminated server may request initiation of packet mobile-terminated call connection and IP resolve, register assigned IP address and transmit the IP address to the DNS. A mobile-terminated GGSN may obtain address information of a SGSN to which the packet mobile-terminated subscriber belongs from a HLR and request initiation of the packet mobile-terminated call connection. A SGSN may request initiation of the packet mobile-terminated call connection, select the GGSN for establishing the packet mobile-terminated call and request establishment of a session connection for the packet mobile-terminated call connection. A GGSN may assign an IP address to the packet mobile-terminated subscriber, establish a session, transmit the assigned IP address to the mobile-terminated server and transmit user traffic received from the Internet host to the packet mobile-terminated subscriber through the SGSN and a base station.
