Apparatus and method for handling error for service flow modification a broadband wireless communication network
First Claim
1. A wireless communication network supporting a Mobile Station (MS) initiated Service Flow (SF) parameter modification process, the network comprising:
- a base station (BS) configured to receive an SF modification request message to modify an SF from the MS, the BS configured to determine whether there is information on the SF upon receiving the SF parameter modification request message, send a path modification request message to a serving Service Flow Authorization (SFA) when there is the information on the SF, and send an SF modification response message which comprises a Confirmation Code (CC) ‘
Reject SF not found’
to the MS when there is no information on the SF;
the serving SFA configured to determine whether there is information on the SF upon receiving the path modification request message, send a resource reservation request message to an anchor SFA when there is the information on the SF, and send a path modification response message that comprises a Failure Indication (FI) ‘
Requested Context Unavailable’
to the BS when there is no information on the SF; and
the anchor SFA configured to determine whether there is information on the SF upon receiving the resource reservation request message, and sending a resource reservation response message which comprises the FI ‘
Requested Context Unavailable’
to the serving SFA when there is no information on the SF.

Abstract
A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code ‘Reject SF not found’ to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) ‘Requested Context Unavailable’ to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI ‘Requested Context Unavailable’ to the serving SFA when there is no information on the SF.

10. A method for an operation of a Mobile Station (MS) in a wireless communication network, the method comprising:
-
sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF; starting a timer corresponding to the SF modification request message at the same time as sending the SF modification request message; and when the timer expires before an SF modification response message is received from the BS, proceeding with an MS initiated SF deletion process. - View Dependent Claims (11)

12. A method for an operation of a Base Station (BS) in a wireless communication network, the method comprising:
-
determining whether is information of a Service Flow (SF) upon receiving an SF parameter modification request message; when there is the information on the SF, sending a path modification request message to a serving Service Flow Authorization (SFA); and when there is no information on the SF, sending an SF modification response message which comprises a Confirmation Code (CC) ‘
Reject SF not found’
to a Mobile Station (MS). - View Dependent Claims (13, 14, 15, 16)

17. A method for an operation of an Access Service Network GateWay (ASN-GW) that acts as a serving Service Flow Authorization (SFA) in a wireless communication network, the method comprising:
-
when receiving a path modification request message for modifying an SF from a Base Station (BS), determining whether there is information on the SF; when there is the information on the SF, sending a resource reservation request message to an anchor SFA; and when there is no information on the SF, sending a path modification response message which comprises a Failure Indication (FI) ‘
Requested Context Unavailable’
to the BS. - View Dependent Claims (18, 19, 20, 21)

22. A method for an operation of an Access Service Network GateWay (ASN-GW) that acts as an anchor Service Flow Authorization (SFA) in a wireless communication network, the method comprising:
-
when receiving a resource reservation request message for modifying an SF from a serving SFA, determining whether there is information on the SF; and when there is no information on the SF, sending a resource reservation response message comprising a Failure Indication (FI) ‘
Requested Context Unavailable’
to the serving SFA. - View Dependent Claims (23, 24)
