System and method for pushing content to a terminal utilizing a network-initiated data service technique
First Claim
1. A method comprising:
- generating a request for a subscription to a push service over a first network on behalf of a terminal in a second network to obtain push content;
initiating establishment of a data session with the terminal via a network address translator or a firewall in response to receiving the request;
registering a network address assigned to the terminal associated with the first network in accordance with establishment of the data session;
causing, at least in part, transmission of the push content over the first network and via the network address translator or the firewall to the terminal;
causing, at least in part, transmission of a trigger to the terminal over a communication channel independent of the network address translator or the firewall, in response to receiving subsequent push content in accordance with the push service;
re-registering the terminal after the transmission of the trigger; and
causing, at least in part, transmission of the subsequent push content over the first network and via the network address translator or the firewall to the terminal based upon the re-registration.

Abstract
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.

9. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following, generate a request for a subscription to a push service over a first network on behalf of a terminal in a second network to obtain push content, initiate establishment of a data session with the terminal via a network address translator or a firewall in response to receiving the request, register a network address assigned to the terminal associated with the first network in accordance with establishment of the data session, transmit the push content over the first network and via the network address translator or the firewall to the terminal, transmit a trigger to the terminal over a communication channel independent of the network address translator or the firewall, in response to receiving subsequent push content in accordance with the push service, re-register the terminal after the transmission of the trigger, and transmit the subsequent push content over the first network and via the network address translator or the firewall to the terminal based upon the re-registration. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:
-
generating a request for a subscription to a push service over a first network on behalf of a terminal in a second network to obtain push content; initiating establishment of a data session with the terminal via a network address translator or a firewall in response to receiving the request; registering a network address assigned to the terminal associated with the first network in accordance with establishment of the data session; transmitting the push content over the first network and via the network address translator or the firewall to the terminal; transmitting a trigger to the terminal over a communication channel independent of the network address translator or the firewall, in response to receiving subsequent push content in accordance with the push service; re-registering the terminal after the transmission of the trigger; and transmitting the subsequent push content over the first network and via the network address translator or the firewall to the terminal based upon the re-registration. - View Dependent Claims (16, 17)
