Method and system for integration of second generation and third generation wireless networks
First Claim
1. A method of providing packet data services comprising the steps of:
- requesting of packet-data services by a user located in a first network;
assigning access resources to the user in an inter-working function of the first network;
establishing by the inter-working function of a link to a packet data service node in a second network;
negotiating via the inter-working function of a point-to-point protocol connection between the user in the first network and the packet data service node in the second network; and
providing the packet data services to the user via the inter-working function by the packet data service node.

Abstract
An inter-working function in a second generation wireless network is used as a transition node for provision of packet-data services by a packet-data service node located in a third generation network. Mobile stations operating in the second generation network that request packet-data services are connected to the packet-data service node via the inter-working function, wherein the inter-working function extends a point-to-point protocol connection between the mobile station and the packet-data service node. In the event that the mobile station roams between the second generation and the third generation networks, either dormant or hard handoff procedures can be employed that allow a previously-established point-to-point protocol connection to be reused without being renegotiated following the handoff.

9. A system for providing packet data services comprising:
-
an inter-working function located in a first network and serving as a transition node between a packet data service node located in a second network and at least one mobile station;
a packet data service node located in the second network and interoperably connected to the inter-working function; and
at least one mobile station located in the first network and interoperably connected to the inter-working function, wherein the at least one mobile station receives services from the packet data service node via the interworking function. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24)

17. An inter-working function located in a first network and interoperably connected to a packet data service node located in a second network and to at least one mobile station located in the first network, wherein the inter-working function serves as a transition node between the at least one mobile station and the packet data service node for provision of packet data services by the packet data service node to the at least one mobile station.
