Abstract
A communication network comprises a broadcast teleservice message center generating broadcast teleservice messages. The broadcast teleservice message center is connected to a circuit-switched network over an interface that uses a first messaging protocol. The broadcast teleservice message center includes an interworking function to connect the broadcast teleservice message center to a packet-switched network over an interface that uses a second messaging protocol. Broadcast teleservice messages transmitted over said first interface to mobile terminals having service with the said circuit-switched network are converted by the interworking function to a format specified by the second messaging protocol for delivery over the packet-switched network to mobile terminals having service with the packet-switched network.
