METHOD FOR PERFORMING ZONE SWITCHING IN BROADBAND WIRELESS ACCESS SYSTEM
First Claim
1. A method, by a mobile station capable of communicating in accordance with a first protocol and a second protocol, of performing handover and zone switching from a serving base station configured to operate only in accordance with the first protocol to a target base station configured to operate in accordance with the first and the second protocol, the method comprising:
- receiving, in the mobile station and from the target base station, a ranging response message including a zone switching type/length/value (TLV) parameter used to perform zone switching from a mobile station support zone of the target base station corresponding to the first protocol (LZone) to a mobile station support zone of the target base station corresponding to the second protocol (MZone); and
transmitting, from the mobile station to the target base station, a request for bandwidth for transmitting a ranging request to the MZone using the zone switching TLV parameter.

Abstract
A device, system and method for performing zone switch based handover in a legacy serving base station by an advanced mobile station (AMS), the method including receiving a ranging response (RNG-RSP) message including a zone switching TLV parameter necessary to perform zone switching to an advanced mobile station support zone (MZone) from a legacy zone (LZone) of a target advanced base station (ABS), and requesting a bandwidth for transmitting an advanced air interface ranging request (AAI_RNG-REQ) message to the MZone using the zone switching TLV parameter.

13. A method, by a target base station capable of communicating in accordance with a first protocol and a second protocol, of performing handover and zone switching from a serving base station, configured to operate only in accordance with the first protocol, of a mobile station configured to operate in accordance with the first and the second protocol, the method comprising:
-
transmitting, from the target base station to the mobile station, a ranging response message including a zone switching type/length/value (TLV) parameter used to perform zone switching from a mobile station support zone of the target base station corresponding to the first protocol (LZone) to a mobile station support zone of the target base station corresponding to the second protocol (MZone); and receiving, from the mobile station by the target base station, a request for bandwidth for transmitting a ranging request to the MZone using the zone switching TLV parameter. - View Dependent Claims (14, 15, 16, 17)

18. A mobile station configured to communicate in accordance with a first protocol and a second protocol, and to perform handover and zone switching from a serving base station configured to operate only in accordance with the first protocol to a target base station configured to operate in accordance with the first and the second protocol, the mobile station comprising:
-
a reception module; a transmission module; and a processor operatively connected to the transmission and reception modules, wherein the processor is configured to receive, from the target base station, a ranging response message including a zone switching type/length/value (TLV) parameter used to perform zone switching from a mobile station support zone of the target base station corresponding to the first protocol (LZone) to a mobile station support zone of the target base station corresponding to the second protocol (MZone); and transmit, to the target base station, a bandwidth request message including a request for bandwidth for transmitting a ranging request to the MZone using the zone switching TLV parameter. - View Dependent Claims (19, 20, 21, 22, 23)
