A multicast status availability indication from an anchor ( 24 ) is provided to a plurality of base nodes ( 22 ) that are part of a multicast group serviced by the anchor ( 24 ). The availability status indication in one example is sent autonomously by the anchor ( 24 ) independent of any inquiry or attempted setup of a new session with that anchor by a base mode ( 22 ). The base modes ( 22 ) maintain a candidate anchor set that includes information regarding currently available anchors for establishing new sessions, for example. |
