Abstract
A Short Message Service (SMS) message is communicated to a mobile user equipment (MUE) over an Internet Protocol (IP) network using an IP communication. An SMS network includes a Short Message Service Centre (SM-SC), a gateway mobile switching centre (GMSC), the SMS network communicating SMS messages. An IP/SMS gateway communicates between the SMS and IP networks. A home location database maintains address data identifying a current location of a MUE. After interrogation by the GMSC, the home location database provides the GMSC an address of the IP/SMS gateway, stored in association with the subscriber identify number. The GMSC sends the SMS message to the IP/SMS gateway. The IP/SMS gateway retrieves an IP address corresponding to the mobile subscriber number pre-stored in an IP/SMS database associated with the IP/SMS gateway. The IP/SMS gateway communicates the SMS message to the MUE at the retrieved IP address via the IP network.
