Abstract: Methods and systems for providing two-way initiated, bi-directional communication with wireless devices using connection-based or connection-less protocols, such as, for example, TCP/IP and UDP/IP, are provided. Example embodiments provide an Address Management Proxy System (“AMPS”), which enables devices and systems connected to a public internet, such as the Internet, to initiate communication with and to send data to wireless devices connected to a private wireless network, without exposing the non-routable private addresses of these wireless devices. The AMPS allocates a public (routable) network address for temporarily use by a requesting device on a public network to communicate with a wireless device on a wireless network. In one embodiment, a pool of public addresses, for example, public IP addresses, is maintained by the AMPS and allocated dynamically to wireless network devices as required.
