Abstract

Methods, systems, and apparatuses are provided for data communication with user communication devices via a network address translator (NAT). In one example, a set of proxy servers is configured to effect communications through mapped data-communication paths of the NAT during data communication sessions through or with the user communication devices. The mapped paths are susceptible to being unmapped by the NAT if the mapped path is unused for a threshold duration of time. The proxy servers maintain the mapped paths through the NAT by prompting the user communication devices to communicate data to the set of proxy servers, for a duration of time exceeding a threshold duration of time.
