Abstract
An LTE subscriber database pushes a registration notification to a SMSC or IP-SM-GW when subscriber registers/deregisters to LTE. The subscriber registration information is stored in local database. Thus, MT SMS may be delivered to a registered subscriber without querying the subscriber database each time for registration information. An exemplary apparatus includes an interface for receiving a registration status message for a mobile device over a broadband network, a subscriber database, and a control system for storing subscriber information in response to receipt of the registration status message and forwarding a notification of subscriber registration status including subscriber registration information to a first network device when the mobile device registers or deregisters to the broadband data network.
