Abstract

A wireless communication system (200) comprises a connectionless packet network (201) coupled to a plurality of sites (203-208) that are in wireless communication with a plurality of subscriber units (210-217) logically arranged into a plurality of talk groups having corresponding talk group identifications. In one embodiment, each site maintains mappings (220-225) o f at least one multicast address to at least one talk group identification. In another embodiment, individual subscriber units maintain such mappings (320) . When a subscriber unit affiliates with a given site and talk group (501, 601 ), the site identifies a multicast address corresponding to the talk group. Bas ed on the multicast address, the site can participate in traffic targeted for t he multicast address and, consequently, for the talk group. In this manner, mobility processing is decentralized, system scalability is improved and cal l setup delays are minimized.
