Auto-attach signaling used as wireless local area network (WLAN) selection criterion

Abstract:

A method for implementing auto attach for a shortest path bridging (SPB) network comprises determining, on an access point, that an auto attach device communicating in a SPB network is enabled for auto attach, and an advertisement is transmitted to a mobile station. The access point acts a proxy between the mobile station and the auto-attach device by communicably coupling the auto attach device and the mobile station via the access point. A virtual local area network (VLAN) identification and service instance identifier (I-SID) is received from the mobile station, when is then transmitted to the auto-attach device. A VLAN (independent of any static VLAN associated with the WLAN) is created off of the VLAN identification and an indication that the I-SID and the VLAN have been accepted. Data communications are then provided between the mobile station and the auto attach device via the VLAN and the access point.
