Abstract: A wireless communication network exchanges wireless data with wireless communication devices and transfers device data indicating device locations and device status to a network server. A sensor system detects a trigger condition and responsively determines proximate wireless communication devices. The sensor system transfers indications of the trigger condition and the currently proximate wireless communication devices to the network server. The network server processes the device data, trigger condition, and proximate wireless communication devices to generate notice data indicating the trigger condition and to select at least one of the wireless communication devices for receipt of the notice data. The network server transfers the notice data to the selected wireless communication devices over the wireless communication network.

Abstract: A communication gateway receives an Internet Protocol (IP) message sourced from a first IP address and directed to a second IP address. The gateway associates the first IP address with a code. The gateway processes the second IP address to identify a Radio Access Network (RAN) address. The gateway transfers the IP message directed to the RAN address and sourced from the second IP address. The IP message uses the code as the source port number. A base station receives the IP message, and in response to the RAN address, wirelessly transfers the IP message to a routing system. The routing system wirelessly receives the IP message and forwards the IP message based on the second IP address which is now in the source address field.
