Abstract: A wireless communication network transfers a data message to a User Equipment (UE). A wireless network control system registers the UE, and in response, transfers a UE registration notice for the UE and the wireless network control system to a wireless network database system. The wireless network database system receives the UE registration notice, and in response, transfers the UE registration notice to a message center. The message center receives the UE registration notice. The message center receives the data message for the UE, and in response, transfers the data message to the wireless network control system based on the UE registration notice. The wireless network control system receives the data message, and in response, transfers the data message to the UE.

Abstract: A subscriber information entity of a home wireless carrier network may receive an authentication request for a user device from a network element of a partner wireless carrier network. The authentication request may include a network element identifier of the network element. An authentication response for the authentication request is then sent to the network element of the partner wireless carrier network. Further, the network element identifier of the network element is stored in a subscriber profile for the user device. A registration request for the user device is then received from a particular network element of a wireless carrier network, in which the registration request includes a corresponding network element identifier of the particular network element. A registration response to the particular network element of the wireless carrier network may be sent when the corresponding network element identifier matches the network element identifier.
