Radio packet data terminal and method of determining internet interworking protocol address
First Claim
1. A method of determining Internet interworking protocol address, comprising:
- transmitting mobile station packet calls from a mobile terminal of a mobile station to a radio network controller in a radio packet data network and registering as a packet data service option of the mobile terminal one of a simple interworking protocol (SIP) option, a mobile interworking protocol (MIP) option, and a unique interworking protocol (UIP) option in accordance with a response to the transmitted mobile station packet calls;
establishing a point-to-point (PPP) link by calling data service packets in accordance with the option registered in the mobile terminal after the registration of the packet data service option and releasing a packet channel of the mobile terminal if a term of a PPP link timer of the radio network controller expires and a present state is a dormant-open state; and
re-establishing the established PPP link by re-transmitting the mobile station packet calls to a new radio network controller and transmitting upper layer data on a virtual network pipeline (VNP) if a handoff is generated between the mobile station and the new radio network controller in the dormant-open state of the PPP link.

Abstract
A radio packet data terminal and a method of determining an Internet interworking protocol address which can easily provide a mobile Internet protocol service and a mobile Internet service by adding a packet data service option and an Internet protocol address option to an originating message to be transmitted to a base transceiver station or by adding information on the system address for interworking packet data to be connected, the present state of the packet data connection, the purpose of the packet data service connection, etc., to the originating message, when the radio packet data service for connecting with Internet is requested. According to the radio packet data terminal, a simple interworking protocol (SIP) option if the mobile terminal does not have a fixed IP address, a mobile interworking protocol (MIP) option is determined if the mobile terminal has the fixed IP address or is connected to a personal computer (PC), and a unique interworking protocol (UIP) option is determined if the mobile terminal is permanently provided with an Internet interworking protocol. Accordingly, the radio packet data terminal provides an Internet protocol option, connection address option, and state option of the packet data link when the packet data service is requested.

6. A radio packet data terminal, comprising:
-
a first mobile terminal determined by a simple interworking protocol (SIP) option to provide a mobile data service only to a network interworking protocol (IP) after connecting with Internet if the radio packet data terminal does not have a fixed IP address;
a second mobile terminal determined by a mobile interworking protocol (MIP) option to provide the mobile data service to a radio LAN port including a home agent and a foreign agent if the radio packet data terminal has the fixed IP address or is connected to a personal computer (PC); and
a third mobile terminal determined by a unique interworking protocol (UIP) option to provide the mobile data service to its own interworking function device if the radio packet data terminal is permanently provided with an Internet interworking protocol. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of determining an Internet interworking protocol address, comprising:
-
establishing a mobile station packet call between a mobile terminal of a mobile station and a first radio network controller in a radio packet data network and registering a packet data service option of the mobile terminal;
establishing a point-to-point (PPP) link by calling data service packets in accordance with the registered service option and releasing the PPP link at a prescribed time; and
re-establishing the PPP link by re-transmitting mobile station packet call to a second radio network controller and transmitting upper layer data on a virtual network pipeline (VNP) if the mobile packet call is handed off to the second radio network controller while the PPP link is in a dormant-open state, wherein the packet data service option is one of a simple interworking protocol (SIP) option, a mobile interworking protocol (MIP) option, and a unique interworking protocol (UIP) option, and is registered in accordance with a response to the established mobile station packet call. - View Dependent Claims (14, 15, 16, 17, 18)
