Abstract
An architecture is described for providing IP push-to-talk (IPP2T) service using a wireless local area network (WLAN) serving a plurality of subscriber terminals (STs), having at least one broadband access network terminal (BANT), the BANT coupled to and interacting with at least one of a plurality of Access Points (APs) via a local area network (LAN), the plurality of APs in communication with the plurality of subscriber terminals; a multicast-enabled network, the multicast-enabled network coupled to and interacting with at least one BANT via a broadband access network; an IP network coupled to, and interacting with, the multicast-enabled network via an edge router; and a WLAN mobile radio service (WLMRS) controller (WLMRSC) coupled to and interacting with the IP network via a multicast-enabled router (MR).
