Abstract:
1. A system for delivering SMS messages to a mobile terminal, comprising: an SMS message center, includes SMS SS7 circuitry for transmitting SMS messages over an SS7 network, and includes SMS IP circuitry for transmitting SMS messages over an IP network to a specified IP port of a specified gateway GPRS support node; SMS processing circuitry coupled to the SMS SS7 circuitry and to the SMS IP circuitry for delivering messages thereto for transmission to a mobile terminal; a gateway GPRS support node (GGSN) having the specified IP port for receiving SMS messages transmitted in an IP protocol over the IP network from the SMS message center; a serving GPRS support node (SGSN) for receiving SMS messages from the gateway GPRS support node, the messages being received in a GPRS tunneling protocol and in an IP protocol; wherein the SMS processing circuitry is operable to determine whether to transmit the SMS message to the SGSN by way of the SS7 network or to the GGSN by way of the IP port and further wherein the GGSN is operable to receive SMS messages in a data packet format and to convert the messages to a legacy format for transmission according to a GPRS tunneling protocol; and wireless transceiver circuitry for receiving the SMS messages from the SGSN, the wireless transceiver circuitry for delivering the SMS message to the mobile terminal.
