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.

A type of network traffic associated with a packet received from a remote node of an access network is determined. A first interface logic routes the packet to a radio network controller (RNC) if the packet is received from an Internet protocol-basestation (IP-BTS) access network and destined to a packet core network. The RNC forwards the packet to a component of the packet core network. A second interface logic routes the packet to the component of the packet core network, including aggregating other packets of the same type received from other remote nodes, if the packet is received from a femto cell and destined to the packet core network. A breakout logic routes the packet to a destination of the Internet directly to enable the packet to reach the Internet without having to route the packet to the component of the packet core network, if the packet is destined to the Internet.
