Patent ID: 8804658

Claim:
A method for handover in a wireless network supporting both IEEE 802.16e zone and IEEE 802.16m zone, the method comprising: scanning neighboring cells by a mobile station, wherein the mobile station is served by an IEEE 802.16e-only serving base station or by an IEEE 802.16e zone of an IEEE 802.16e/16m-coexistence serving base station; performing an IEEE 802.16e handover procedure such that the mobile station handovers from the serving base station to an IEEE 802.16e zone of a target base station, wherein the mobile station is indicated with IEEE 802.16e and IEEE 802.16m coexistence capability of the target base station by reading a reserved bit in a Frame Control Header (FCH), and wherein the mobile station further obtains IEEE 802.16m Superframe Header (SFH) information of an IEEE 802.16m zone of the target base station; and performing a zone-switch procedure such that the mobile station switches from the IEEE 802.16e zone of the target base station to the IEEE 802.16m zone of the same target base station.
