Abstract: Several related methods and apparatus for re-establishing communication for a wireless communication device after a communication loss between the wireless device and a wireless communication network are disclosed. In one illustrative example, the wireless network broadcasts identifiers of wireless devices associated with communication losses in the wireless network over a control channel. After regaining signal coverage, a wireless device monitors the control channel to decode and compare each broadcasted identifier with an identifier of the wireless device. Based on a match between a broadcasted identifier and the identifier of the wireless device, the wireless device transmits a control message which informs the wireless network of the presence of the wireless device. Otherwise, the wireless device normally refrains from transmitting the control message to the wireless network.

Abstract: A system and method for redirecting data from a host system (or messaging server) to one or more mobile data communication devices via a wireless packet data network is provided in which the wireless packet data network dynamically assigns addresses to the one or more mobile data communication devices on an as-needed basis. A redirector application operating at the host system is configured by each user to continuously redirect certain data to the wireless packet data network, as the data is received (or otherwise altered) at the host system. Two methods are provided for communicating the redirected data from the network to the mobile device. In a first method, the mobile device is configured to periodically contact a store-and-forward server within the wireless network, which, when contacted, assigns a network address to the mobile device and then transmits the stored, redirected data to the mobile device.
