Abstract
Methods, systems, and computer program products for routing a short message service (SMS) message from a 2G network to a dual mode 2G/session initiation protocol (SIP) device are disclosed. According to one method, at a communications signaling message routing node, a 2G mobility location information query message for obtaining a delivery address for an SMS message to be sent to a dual mode 2G/SIP device roaming in a SIP-based network is received. The mobility location information query message includes a destination subscriber identifier associated with the dual mode 2G/SIP device. SIP mobility location information for the dual mode 2G/SIP device in the SIP-based network is determined based on the destination subscriber identifier. The method also includes providing the SIP mobility location information to a query originator.
