Distributed architecture for IP-based telemetry services
A system and method are described whereby an IP telemetry gateway is hosted by an MVNO in order to relay the telemetry information between remote devices located in an IP network and telemetry servers operated by legacy telemetry customers. In an embodiment, the IP network is a CDMA2000 1X wireless network. Once the IP network identifies a device as part of the telemetry network, it assigns such device a static private IP address. A VPN connection is used to extend the private network of remote devices to the IP telemetry gateway. The IP telemetry gateway maps each remote device's legacy address to its corresponding IP address in order to communicate with the legacy servers and the wireless network via circuit switched and packet data connections respectively. Preferably, the remote devices maintain an always on data connection to allow the telemetry servers to address the remote devices at any time.
