Abstract

The invention relates to a message processing method and apparatus in a portable Internet system, in which a base station of the portable Internet system is designed to have a number of connection processors and connection controllers. This can increase the number of mobile subscriber stations that a single base station can provide a service and efficiently manage information necessary for providing a service to the mobile subscriber stations.

Claims

1. A portable Internet system for providing Internet service to plurality of terminals comprising:

at least one connection-processor for processing an initial ranging procedure or a basic capability procedure for the terminal and providing connection information of the terminal; and

at least one connection-controller for processing an authentication procedure and a Quality of Service (QoS) negotiation procedure according to connection information of the terminal received from the connection-processor.

2. The portable Internet system according to claim 1, wherein the connection-processor is adapted to transmit at least one selected from a group consisting of basic Connection Identifier (CID) information, Primary Management CID information and basic capability information according to the initial ranging procedure or the basic capability procedure.

3. The portable Internet system according to claim 1, wherein the connection-processor is adapted to, upon receiving a connection information request message containing MAC address information from the terminal, allocate basic CID information and Primary Management CID information to the terminal, and upon receiving a capability request message containing physical layer information and authentication policy information, set basic capability information of the terminal.

4. The portable Internet system according to claim 1, wherein the connection controller is adapted to, upon receiving an authentication request message via the connection-processor, exchange authentication-related parameter information with an authentication server to perform an authentication procedure, and upon receiving a registration request message via the connection-processor, acquire subscriber information of the terminal from a subscriber information server to provide registration information.

5. The portable Internet system according to claim 4, wherein the registration information comprises at least one selected from a group consisting of secondary management CID information, key information and IP address information.

6. The portable Internet system according to claim 1, wherein the connection-controller comprises:

a wireless interface for setting a wireless link with the terminal;

a connection processor for processing the initial ranging procedure or the basic capability procedure according to the request message received via the interface or generating and transmitting an internal request message containing the connection information to the connection-controller; and

an internal interface for transmitting the internal request message to the connection-controller and receiving an internal response message from the connection-controller.

7. The portable Internet system according to claim 1, wherein connection-controller comprises:

a message exchanger for receiving an internal request message from the connection-processor and transmitting an internal response message to the connection-processor; and

a controlling processor for processing the authentication procedure and the QoS procedure by acquiring parameter information from a server connected via a network according to the internal request message received via the message exchanger, and generating the internal response message containing registration information according to the procedures.

8. The portable Internet system according to claim 1, wherein the connection-controller comprises:

a physical layer;

an encryption layer for processing PDU authentication and encoding;

a media access control (MAC) Protocol Data Unit (PDU) processing layer for forming a PDU by using a MAC header and a MAC subheader;

a MAC scheduling layer for scheduling packets; and

a wireless link-controlling layer for allocating key information and connection ID information, transmitting connection information to the connection controller, and receiving registration information from the connection-controller.

9. The portable Internet system according to claim 1, wherein the connection-controller comprises:

an Automatic Repeat Request (ARQ) block layer for exchanging a subheader with the connection-controller to process ARQ;

a packet header suppression layer for compressing a packet header;

a Packet Classification layer for classifying packets and mapping the packets according to a service flow;

a security management layer for managing privacy key information;

a connection control layer for allocating tunnel key information and service flow ID information and receiving connection information from the connection processor;

a network gateway layer for authenticating packets, allowing packet reception from a network; and

a mobility management layer for supporting the mobility of the terminal.

10. A message processing method in a portable Internet system, which comprises at least one terminal, at least one connection processor and a connection controller internally connected with the connection processor, the method comprising steps of:

allocating basic Connection Identifier (CID) information and primary management CID information to the terminal upon receiving a connection information request message from the terminal;

setting basic capability information of the terminal according to physical layer information and authentication policy information upon receiving a capability request message from the terminal;

exchanging authentication-related parameter information with an authentication server to process an authentication procedure upon receiving an authentication request message via the connection processor from the terminal.

11. The message processing method according to claim 10, further comprising:

acquiring subscriber information of the terminal from a subscriber information server to provide registration information upon receiving a registration request message via the connection processor from the terminal.

12. The message processing method according to claim 10, further comprising:

upon receiving a service request message from the terminal, transmitting service flow information, Convergence sublayer (CF) information, key information and IP information of the terminal to the connection controller upon receiving a service request message from the terminal; and

negotiating service quality with a policy server.

transmitting basic CID information, primary management CID information and basic capability information of the terminal to the connection controller; and

transmitting registration information to the connection processor.

14. The message processing method according to claim 13, wherein the registration information comprises at least one selected from a group consisting of secondary management CID information, key information and IP address information.

15. The message processing method according to claim 12, wherein the step of negotiating further comprises:

negotiating service quality using service flow information, Convergence sublayer (CF) information, key information and IP information of the terminal.

16. An authentication processing method in a portable Internet system, which comprises at least one terminal, at least one connection processor and a connection controller internally connected with the connection processor, the method comprising steps of:

transmitting to the connection controller an Hbis-Security Request message that requests authentication-related parameter information of the terminal upon receiving an authentication request message from the terminal; and

exchanging authentication-related parameter information with an authentication server to process an authentication procedure upon the Hbis-Security Request message from the connection processor; and

transmitting to the connection processor an Hbis-Security Response message that includes authentication-related parameter information of the terminal; and

transmitting to the terminal an authentication response message upon the Hbis-Security Response message from the connection controller.

17. A method for acquiring subscriber information of a terminal in a portable Internet system, which comprises at least one terminal, at least one connection processor and a connection controller internally connected with the connection processor, the method comprising steps of:
