6. The system as recited in claim 1 , further comprising:

an internetwork interface, operatively coupled to said packetized data modem via the packetized data network, configured to transmit the notification to a dual mode mobile station.

7. The system as recited in claim 6 , wherein said internetwork interface comprises:

a second service-oriented tunneling link access control processor, configured to encapsulate said IGPM to render said lower level packetized data.

8. A system for providing notification of a circuit switched event over a packetized data network, the system comprising:

an internetwork interface, configured to transmit lower level packetized data over the packetized data network that comprises the notification, said internetwork interface comprising:

a first service-oriented tunneling link access control processor, configured to encapsulate an Improved 1x Layer 3 General Page Message (IGPM) to render said lower level packetized data, wherein said IGPM comprises a service option field and does not comprise the following fields corresponding to a 1x Layer 3 protocol data unit (PDU) General Page Message: CONFIG MES SEQ, ACC MSG SEQ, CLASS 0 DONE, CLASS 1 DONE, TMSI DONE, ORDERED TMSIS, BROADCAST DONE, RESERVED, and ADD LENGTH.

9. The system as recited in claim 8 , wherein said IGPM comprises a Layer 3 (PDU) compliant with the CDMA2000 1xRTT tunneling protocol.

10. The system as recited in claim 9 , wherein said service option field prescribes a circuit switched service type for operation of a dual mode mobile station.

11. The system as recited in claim 10 , wherein said circuit switched service type comprises an enhanced variable rate codec (EVRC) option.

12. The system as recited in claim 8 , further comprising:

a packetized data modem, operatively coupled to said internetwork interface, configured to receive said lower level packetized data over the packetized data network that comprises the notification.

13. The system as recited in claim 12 , wherein said packetized data modem comprises:

a second service-oriented tunneling link access control processor, configured to decapsulate said Improved 1x Layer 3 General Page Message (IGPM) from said lower level packetized data.

14. The system as recited in claim 13 , wherein said packetized data modem is disposed within a dual mode mobile station that comprises a modem compatible with CDMA2000 1xRTT protocol, and wherein said packetized data modem comprises a modem compatible with Long Term Evolution (LTE) protocol.

15. A method for providing notification of a circuit switched event over a packetized data network, the method comprising:

within an internetwork interface, encapsulating an Improved 1x Layer 3 General Page Message (IGPM) to render lower level packetized data, wherein said IGPM comprises a service option field and does not comprise the following fields corresponding to a 1x Layer 3 protocol data unit (PDU) General Page Message: CONFIG MES SEQ, ACC MSG SEQ, CLASS 0 DONE, CLASS 1 DONE, TMSI DONE, ORDERED TMSIS, BROADCAST DONE, RESERVED, and ADD LENGTH; and

transmitting the data over the packetized data network.

16. The method as recited in claim 15 , wherein the IGPM comprises a Layer 3 (PDU) compliant with the CDMA2000 1xRTT tunneling protocol.

17. The method as recited in claim 16 , wherein the service option field prescribes a circuit switched service type for operation of a dual mode mobile station.
