Claims

1. A computer program product for enabling communications between a CDMA (Code Division Multiple Access) packet data system and a GPRS (General Packet Radio Service) system, wherein a CDMA 2000 packet data native subscriber using Mobile IPV4 (Internet Protocol version 4) roams from a home CDMA 2000 packet data system to a visited GPRS system comprising a SGSN (Serving GPRS Support Node), comprising:

a computer-readable storage medium comprising;

code for coupling the home system to the visited system to enable communication between the home system and the visited system, wherein the home CDMA 2000 packet data system comprises a ANSI (American National Standards Institute)-41 home location register, an AAA (Authentication, Authorization, and Accounting) entity, and a home agent; and

code for providing a distinct interface for each of the ANSI-41 home location register, the AAA entity, and the home agent.

2. A computer program product for enabling communications between a CDMA (Code Division Multiple Access) packet data system and a GPRS (General Packet Radio Service) system, wherein a CDMA 2000 packet data native subscriber using Simple IP roams from a home CDMA 2000 packet data system to a visited GPRS system comprising a SGSN, (Serving GPRS Support Node), comprising:

a computer-readable storage medium, comprising;

code for coupling the home system to the visited system to enable communication between the home system and the visited system, wherein the home CDMA 2000 packet data system comprises a ANSI-41 home location register, an AAA (Authentication, Authorization, and Accounting) entity, and a LNS (Layer 2 Tunneling Protocol Network Server); and

code for providing a distinct interface for each of the ANSI-41 home location register, the AAA entity, and LNS.

3. A computer program product for enabling communications between a CDMA (Code Division Multiple Access) packet data system and a GPRS (General Packet Radio Service) system, wherein a GPRS native subscriber using Mobile IPV4 (Internet Protocol version 4) roams from a home GPRS system to a visited CDMA 2000 packet data system that comprises an ANSI-41 visited location register, an AAA (Authentication, Authorization, and Accounting) entity, and a packet data serving node/foreign agent, comprising:

a computer-readable storage medium, comprising;

code for coupling the home system to the visited system to enable communication between the home system and the visited system, wherein the home GPRS system comprises a GSM home location register, a GGSN, and an AAA entity; and

code for providing a distinct interface for each of the GSM home location register, the GGSN, and the AAA entity.

4. A computer program product for enabling communications between a CDMA (Code Division Multiple Access) packet data system and a GPRS (General Packet Radio Service) system, wherein a GPRS native subscriber using Simple IP roams from home GPRS system to a visited CDMA 2000 packet data system that comprises a ANSI-41 visited location register, a AAA (Authentication, Authorization, and Accounting) entity, and a PDSN/LAC (Packet Data Serving Node/Layer 2 Tunneling Protocol Access Concentrator) entity, comprising:

a computer-readable storage medium, comprising;

code for coupling the home system to the visited system to enable communication between the home system and the visited system, wherein the home GPRS system comprises a GSM home location register, a GGSN, and an AAA entity; and

code for providing a distinct interface for each of the GSM home location register, the GGSN, and the AAA entity.

5. A computer program product for enabling communication between a home CDMA 2000 packet data system and a visited GPRS (General Packet Radio Service) system comprising a SGSN (Serving GPRS Support Node), when a CDMA 2000 packet data native subscriber using Mobile IPV4 roams to a visited GPRS system, comprising:

a computer-readable storage medium, comprising;

code for allowing a subscriber to register over a first interface that couples a GSM home location register emulation module to the SGSN; and

code for allowing the subscriber to register over a second interface that couples an ANSI-41 visited location register emulation module to a ANSI-41 home location register.

6. A computer program product that enables communication between a home CDMA (Code Division Multiple Access) 2000 packet data system and a visited GPRS (General Packet Radio Service) system comprising a SGSN (Serving GPRS Support Node), when a CDMA 2000 packet data native subscriber using Simple IP roams to a visited GPRS system, wherein the home CDMA2000 packet data system comprises a ANSI-41 home location register, an AAA entity, and a LNS, comprising:

a computer-readable storage medium, comprising;

code for coupling a ANSI-41 visited location register to the ANSI-41 home location register via a first interface, wherein the ANSI-41 visited location register allows a subscriber to register over the first interface; and

code for coupling a GSM home location register to the SGSN via a second interface, wherein the GSM home location register allows a subscriber to register over the second interface.

7. A computer program product that enables communication between a home GPRS (General Packet Radio Service) system comprising a GSM home location register, a GGSN, and an AAA (Authentication, Authorization, and Accounting) entity;

and a visited CDMA 2000 packet data system that comprises an ANSI-41 visited location register, an AAA entity, and a packet data serving node/foreign agent, when a GPRS native subscriber using Mobile IPV4 (Internet Protocol version

     4) roams to the visited CDMA 2000 packet data system, comprising;

a computer-readable storage medium, comprising;

code for coupling a home agent emulation module to the packet data serving node/foreign agent via a first interface, wherein the home agent emulation module presents a home agent interface to the visited system; and

code for coupling a SGSN emulation module to the GGSN via a second interface, wherein the SGSN emulation module presents a SGSN interface to the home system to support bearer connectivity between the visited and home networks by providing a packet routing function between the SGSN interface and the home agent interface.

8. A computer program product that enables communication between a home GPRS (General Packet Radio Service) system comprising a GSM home location register, a GGSN, and an AAA (Authentication, Authorization, and Accounting) entity, and a visited CDMA 2000 packet data system that comprises an ANSI-41 visited location register, an AAA entity, and a packet data serving node/LAC entity, when a GPRS native subscriber using Simple IP roams to the visited CDMA 2000 packet data system, comprising:
