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.

Abstract: A method and apparatus for allocating a Unicast Access Terminal Identifier (UATI) to an access terminal in a 1× Evolution Data Only (1×EV-DO) system serving as a high-speed data dedicated system. In order that a temporary identifier is allocated to an access terminal (AT) moving from a source subnet to a destination subnet in 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 from the AT, the destination subnet transmits a temporary-identifier allocation completion request message to the source subnet. The source subnet transmits a temporary-identifier allocation completion response message to the destination subnet in response to the temporary-identifier allocation completion request message.
