Abstract

A core network architecture for supporting an internet protocol based network is disclosed. The system includes a base station which is configured to convert a signal from a first network to an internet protocol network signal and send the converted signal through the internet protocol base network. The network also includes a gateway which is configured to receive the converted signal and deploy the converted signal through the internet protocol base network. In this sense, the internet protocol base network manages the call mobility and delivery of the signal. The base station in this disclosure may be a femto base station and the first network may be a code division multi-access (CDMA) network.

Claims

1. A core network architecture for supporting an internet protocol based network comprising:

a base station configured to convert a signal from a first network signal to an internet protocol network signal and send said converted signal via said internet protocol based network;

a network gateway configured to receive said converted signal and deploy said converted signal though said internet protocol based network, where said internet protocol based network manages the call mobility and delivery of said signal.

2. The core network architecture according to claim 1, wherein said base station is a femtocell base station.

3. The core network architecture according to claim 1, wherein said first network is a code division multi access network.

4. The core network architecture according to claim 1, further comprising an OA&

M configured to initialize relevant data associated with said converted signal.

5. The core network architecture according to claim 4 wherein said relevant data includes power settings.

6. The core network architecture according to claim 4 wherein relevant data includes a pseudo random number offset.

7. The core network architecture according to claim 4 relevant data includes a neighborhood list.

8. The core network architecture according to claim 1 further comprising a feature server configured to provide supplementary services associated with said converted signal.

9. The core network architecture according to claim 1 further comprising an mobile switching center emulator configured to facilitate with authenticating said mobile unit.

10. The core network architecture according to claim 1 further comprising a call session control function configured to provide mobile control for said signal.

12. The method according to claim 10 wherein the call was originated from said code division multi access mobile station.

13. The method according to claim 10 wherein said call was terminated on said code division multi access mobile station.

14. The method according to claim 13 further comprising querying a serving mobile switching center for a temporary routing number.

15. The method according to claim 14 further comprising routing the call based on the temporary routing number.

11. A method for connecting a call for a code division multi access network based mobile on an internet protocol based network comprising:

registering a code division multi access mobile station on a internet protocol based network system employing a base station that is configured to convert a signal from said CDMA mobile station network signal to a session initiation protocol signal;

connecting a call between an end user and said code division multi access mobile unit though said internet protocol based network; and

processing said call through said internet protocol based system.

16. A system for supporting voice and data in a wireless radio broadband data standard in an associated internet protocol multimedia system comprising:

a base station configured to translate a call that originates from a cell division multi access system into Session Initiation Protocol messaging;

a handoff application server configured to facilitate handoff procedures for said call;

a feature server configured to provide service features for said call; and

a network gateway that provides security between said base station and an associated core network and forwards said call through the associated internet protocol multimedia system.

17. The system according to claim 16, wherein said call originated in a code division multi access network.

18. The system according to claim 16, wherein said call is originated in a code division multi access mobile.

19. The system according to claim 16, wherein said base station is a femtocell base station.

20. The system according to claim 16 further comprising a mobility application severer which provides call management services for said call.
