A router system maintains a status of a wireless device of either available or unavailable. The status of available may be indicative of the wireless device being in-coverage with a wireless network, whereas the status of unavailable may be indicative of the wireless device being out-of-coverage with the wireless network. The router system is adapted to receive, from a host service, a user data message that is addressed to an address of the wireless device. The user data message has a user data payload and one or more request parameters, where the one or more request parameters instruct the router system on whether to return at least a portion of the user data message to the host service when the device status is unavailable. In response to the user data message being received at the router system when the device status is available, the router system delivers the user data message to the wireless device via the wireless network. In response to the user data message being received at the router system when the device status is unavailable, the router system fails to delivery the user data message to the wireless device but sends the at least user data message portion to the host service.

System and method of message delivery in a wireless communication network

In one embodiment, a method is provided for managing secure registration of a mobile communications device, the method comprising registering, at a network node, the mobile communications device using a first registration process, the first registration process requiring an authentication key associated with the mobile communications device; processing a request from the mobile communications device, the request including an indication that the mobile communications device is changing to a second registration process; and clearing the authentication key associated with the mobile communications device upon expiration of a time window.
