Abstract
A gateway, system, and method for providing seamless communications to Public Safety and Security (PSS) users operating between a PSS communication network and a cellular communication network irrespective of access technology or switching method. The gateway includes a presence and identity mapping unit for mapping a PSS user identity utilized in the PSS network to a cellular user identity utilized in the cellular network. The gateway provides an interface and establishes a session between the PSS network and a PSS user operating in the cellular network utilizing the mapped cellular user identity. A transcoder converts between PSS and cellular voice coding protocols. A data gateway converts between PSS and cellular data protocols. The gateway dynamically switches between voice and data, and provides group calling, call forwarding, and message replay services across the network interface.
