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.

Registration notification for SMS over LTE

SMS-C's and associated methods are disclosed that attempt to deliver SMS messages over a broadband data network as opposed to a voice network. An SMS-C described herein stores session information for a mobile device that has established a data session over the broadband data network. When the SMS-C receives a Mobile Terminated (MT) SMS message destined for the mobile device, the SMS-C stores the SMS message for delivery. The SMS-C then identifies a routing address for the mobile device over the broadband data network based on the stored session information, and forwards the SMS message to the mobile device directly over the broadband data network based on the routing address.

Direct SMS message delivery over broadband data networks through an SMS-C

Communication networks and methods are disclosed for delivering messages over LTE networks. One embodiment comprises a universal message center operable to deliver messages over an LTE network. The universal message center receives a message intended for a destination mobile device, and determines if the destination mobile device is LTE enabled. If the destination mobile device is LTE enabled, then the universal message center identifies a mobile IP address assigned to the destination mobile device in the LTE network. The universal message center then attempts to forward the message to the destination mobile device over the LTE network based on the mobile IP address. If the destination mobile device is not LTE enabled, then the universal message center identifies a store-and-forward (SFD) message center for an originator of the message, and forwards the message to the SFD message center for store-and-forward processing.

Message delivery over LTE networks

Broadband messaging gateways, SMS-C's, and associated methods are disclosed that attempt to deliver SMS messages over a broadband data network as opposed to a voice network. When a mobile device sends a Mobile Originated (MO) SMS message, the mobile device sends the MO SMS message to a broadband data network instead of the voice network. The broadband data network then routes the MO SMS message to the appropriate SMS-C. When an SMS-C receives a Mobile Terminated (MT) SMS message destined for a mobile device, the SMS-C forwards the MT SMS message to the broadband data network instead of the voice network. Thus, SMS messages are offloaded from the voice network to the broadband data network.
