Data push service system and method using a heterogeneous network
First Claim
1. A system for transmitting push data to a Hybrid Access Terminal (HAT) which can be connected to a circuit network or a packet network, and is registered in a new access network determined by an access network switching operation in a heterogeneous mobile communication system in which at least one circuit network is overlapped with at least one packet network, the system comprising:
- a Packet Service &
Mobility Gateway (PSMG) for acquiring access state and connection information of the HAT from the circuit network and the packet network, and generating an access network switching request of the HAT upon receipt of an external request signal; and
a Push Proxy Gateway (PPG) for acquiring access information of the HAT which will transmit the push data from the PSMG, and transmitting a request message to the PSMG such that the HAT can access a network selected by the push data.

Abstract
A data push service system and method using a heterogeneous network. The system transmits push data to a Hybrid Access Terminal (HAT) in a heterogeneous mobile communication system in which at least one circuit network overlaps with at least one packet network. The HAT can be connected to a circuit network or a packet network, and is registered in a new access network. The system includes a Packet Service & Mobility Gateway (PSMG) for acquiring access state and connection information of the HAT from the circuit network and the packet network, and generating an access network switching request upon receipt of an external request signal; and a Push Proxy Gateway (PPG) for acquiring access information of the HAT which will transmit the push data from the PSMG, and transmitting a request message to the PSMG.

8. A method for transmitting push data to a Hybrid Access Terminal (HAT) which can be connected to a circuit network or a packet network, and registers access state and connection information in a new access network determined by an access network switching operation in a heterogeneous mobile communication system in which at least one circuit network is overlapped with at least one packet network, comprising the steps of:
-
requesting, by a Push Proxy Gateway (PPG), access state and connection information of the HAT to which the push data is to be transmitted, from a Packet Service &
Mobility Gateway (PSMG), when the push data is generated;detecting, by the PSMG, the requested access state and connection information of the HAT, and transmitting the detected information to the PPG; and generating, by the PPG, a request signal when a corresponding HAT is not connected to a selected network corresponding to push data characteristics such that the HAT is switched to the selected network over the PSMG. - View Dependent Claims (9, 10, 11, 12)
