`ABSTRA℃I
`
`A system and method of admission control for authorizing a
`submission of a broadcast message to a broadcast target area
`includes receiving a broadcast message record including the
`broadcast message and the broadcast target area for the broad-
`cast message and validating the authority of a broadcast mes-
`sage originator originating the broadcast message record as a
`function of a broadcast message originator parameter. The
`method also includes identifying a broadcast transmission
`network providing broadcast message transmission to broad-
`
`cast message recei、ringdevices located within the broadcast
`
`target area and validating the broadcast transmission network
`against a broadcast transmission network parameter. The
`method further includes forwarding the broadcast message
`record to an output interface associated with the broadcast
`transmission network for transmission to the broadcast mes-
`sage receiving devices within the broadcast target area.
