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.

Claims

1-21. -21. (canceled)

22. 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; and

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.

23. A method according to claim 22, further comprising:

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.

24. A method according to claim 23, wherein at least one of removal of the terminal from a translation table of the network address translator or the firewall, removal of the terminal from the registration, de-registration initiated by the terminal, and entry by the terminal into an idle mode, occurs prior to the re-registration.

25. A method according to claim 23, further comprising:

causing, at least in part, transmission of subsequent push content through the network address translator or the firewall to the terminal based upon direct subscription to the push service by the terminal, the direct subscription occurring after the re-registration.

26. A method according to claim 22, further comprising:

causing, at least in part, reception of the push content from the push service, before or after registering the network address assigned to the terminal.

27. A method according to claim 25, further comprising:

causing, at least in part, reception of the subsequent push content from the push service, before re-registering the terminal.

28. A method according to claim 22, wherein the push service is originated from the first network or a third network connected to the first network via another network address translator or another firewall.

29. 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, and

transmit the push content over the first network and via the network address translator or the firewall to the terminal.

30. An apparatus of claim 29, wherein the apparatus is further caused to:

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.

31. An apparatus of claim 30, wherein at least one of removal of the terminal from a translation table of the network address translator or the firewall, removal of the terminal from the registration, de-registration initiated by the terminal, and entry by the terminal into an idle mode, occurs prior to the re-registration.

32. An apparatus of claim 30, wherein the apparatus is further caused to:

transmit subsequent push content through the network address translator or the firewall to the terminal based upon direct subscription to the push service by the terminal, the direct subscription occurring after the re-registration.

33. An apparatus of claim 29, wherein the apparatus is further caused to:

receive the push content from the push service, before or after registering the network address assigned to the terminal.

34. An apparatus of claim 32, wherein the apparatus is further caused to:

receive the subsequent push content from the push service, before re-registering the terminal.

35. An apparatus of claim 29, wherein the apparatus comprises a session initiation protocol (SIP) proxy, the first network is a public network, and the second network is a private network.

36. A 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; and

transmitting the push content over the first network and via the network address translator or the firewall to the terminal.

37. A computer-readable storage medium of claim 36, wherein the apparatus is caused to further perform:

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.

38. A computer-readable storage medium of claim 37, wherein at least one of:

removal of the terminal from a translation table of the network address translator or the firewall, removal of the terminal from the registration, de-registration initiated by the terminal, and entry by the terminal into an idle mode, occurs prior to the re-registration.

39. A computer-readable storage medium of claim 37, wherein the apparatus is caused to further perform:

transmitting subsequent push content through the network address translator or the firewall to the terminal based upon direct subscription to the push service by the terminal, the direct subscription occurring after the re-registration.

40. A computer-readable storage medium of claim 36, wherein the apparatus is caused to further perform:

receiving the push content from the push service, before or after registering the network address assigned to the terminal.

41. A computer-readable storage medium of claim 39, wherein the apparatus is caused to further perform:

receiving the subsequent push content from the push service, before re-registering the terminal.
