A wireless system and method for providing informative broadcast services
includes a plurality of base stations, each serving a plurality of
wireless communications device users via a plurality of communications
channels. An alert message is first transmitted to wireless
communications devices advising of the availability of a broadcast
message and identifying an associated communications channel. The base
station then transmits the broadcast message to the plurality of users on
the identified channel. The wireless communications devices may
automatically switch to the broadcast channel, for example, when there is
a weather or other emergency, or may offer the user the opportunity to
change channels. Also, a user may initiate a request to access a
broadcast channel for services such as news, sports, or stock reports on
a subscription basis.
