Abstract
The present invention provides methods, apparatuses, and systems for supporting emergency calls on a WiMAX access network. According to an embodiment of the invention, a method of providing emergency calling in a WiMAX network is provided. The method includes determining whether a call from a subscriber station (SS) is an emergency call. To enable making an emergency call, the minimum bandwidth required to enable SIP signaling is reserved and required resources are allocated from the access service network gateway (ASN-GW) via a base station (BS).
