Method and apparatus for allocating an Unicast Access Terminal Identifier according to an access terminal's movement to subnet in a high-speed data dedicated system
First Claim
1. A method for allocating a temporary identifier to an access terminal (AT) moving from a source subnet to a destination subnet in a high-speed data dedicated system, comprising the steps of:
- transmitting a temporary-identifier allocation completion message from the AT to the destination subnet when the AT moves to the destination subnet while performing a temporary-identifier allocation procedure with the source subnet;
transmitting a temporary-identifier allocation completion request message to the source subnet when the destination subnet receives the temporary-identifier allocation completion message from the AT;
transmitting a temporary-identifier allocation completion response message from the source subnet to the destination subnet in response to the temporary-identifier allocation completion request message; and
allocating a new temporary identifier for the AT at the destination subnet in response to the temporary-identifier allocation completion response message, and transmitting a temporary-identifier allocation completion acknowledgement message to the AT.

Abstract
Disclosed is a method and apparatus for allocating a Unicast Access Terminal Identifier (UATI) to an access terminal (AT) from a source subnet to destination subnet in a 1×Evolution Data Only (1×EV-DO) system serving as a high-speed data dedicated system. The AT transmits a temporary-identifier allocation completion message to the destination subnet when the AT moves to the destination subnet while performing a temporary-identifier allocation procedure with the source subnet. Upon receiving the temporary-identifier allocation completion message, the destination subnet transmits a temporary-identifier allocation completion request message to the source subnet, which in response, transmits a temporary-identifier allocation completion response message to the destination subnet, which in response, allocates a new temporary identifier for the AT, and transmits a temporary-identifier allocation completion acknowledgement message to the AT.

11. An apparatus for allocating a temporary identifier to an access terminal (AT) in a high-speed data dedicated system, the system including a plurality of subnets and providing ATs within the subnets with service using temporary identifiers, the apparatus comprising:
-
a source subnet for receiving a temporary-identifier allocation request message from the AT, allocating the temporary identifier having a subnet code of the source subnet, and transmitting a temporary-identifier allocation response message including the allocated temporary identifier to the AT; and a destination subnet for receiving a temporary-identifier allocation completion message from the AT when the AT moves to the destination subnet while performing an temporary-identifier allocation procedure with the source subnet, transmitting a temporary-identifier allocation completion request message to the source subnet, allocating a new temporary identifier for the AT when receiving a temporary-identifier allocation completion response message responding to the temporary-identifier allocation completion request message from the source subnet, and transmitting a temporary-identifier allocation completion acknowledgement message including the new temporary identifier to the AT. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
