Abstract
Provided is a method and apparatus for facilitating push communication from a first network to a target device of a second network, the second network comprising a packet service network such as a GPRS core network. A private IP address, usable for addressing the target device when the packet service network is in an activated state with respect thereto, is retained. Upon receipt of a first message from the first network, indicative of a push communication for the target device, the packet service network is disposed into the activated state, and a second message, addressed to the private IP address, is transmitted. The second message may be generated by a NAT configured to implement micro-port forwarding. The second message may be generated by a representative device of the second network, configured to receive the first message via a NAT in response to a query generated by the representative device.
