Abstract:
1. A method of exchanging a short message service (SMS) message between networks operating in accordance with different standards, comprising: operating an intermediary system that operates between an ANSI network and a GSM network; receiving, at the intermediary, a routing information request for an SMS message from the GSM network; sending, from the intermediary in response to the routing information request, an acknowledgement message to the GSM network; receiving the SMS message at the intermediary; generating, in the intermediary, an acknowledgement of receipt of the SMS message, and sending the acknowledgement of receipt to the GSM network; and sending the SMS message from the intermediary to the ANSI network, wherein the intermediary is an entity distinct from the GSM and ANSI networks, wherein the step of sending the acknowledgement of receipt to the GSM network is performed only after a response from the ANSI network is received at the intermediary system, and wherein the intermediary operates an intermediary Location Register, an intermediary Transmitting Station, and an intermediary Receiving Station, each of which substantially emulates, respectively, HLR functionality, GSM SMSC functionality and MSC functionality.
