A system is provided for pushing content to a terminal located within a mobile network or a private network. The system includes a network node, such as a Session Initiation Protocol (SIP) proxy, located across a public network from the network including the terminal. The network node is capable of subscribing to a push service on behalf of the terminal such that the network node is also capable of receiving push content in accordance with the push service. Thereafter, the network node is capable of establishing a network-initiated data session with the terminal. In response to the network-initiated data session, the network node is further capable of registering the terminal such that the terminal is capable of receiving the push content based upon the registration.
