Abstract
Location determination for a roaming subscriber device using a short message service (SMS) to contact emergency services, wherein location information is obtained from a visited carrier network on which the originating subscriber device is roaming. An emergency SMS message is first routed to a predetermined emergency services SMSC. The emergency services SMSC then forwards data relevant to the emergency SMS message to an SMS to emergency services mediator. The SMS to emergency services mediator uses data received for the emergency SMS message to obtain location information therefor. Location information for an emergency SMS message is obtained from an LBS platform on a network carrier currently servicing the originating subscriber device. A next hop URI is then determined for the emergency SMS message based on relevant location information. The emergency SMS message is routed to the next hop URI and eventually routed to an appropriate PSAP.
