Abstract
Abstract This invention provides for the use of an index message in a Cell Broadcast Service. An index message is considered to be a special type of Cell Broadcast message which contains general information about actual broadcast messages. The index message is transmitted in a predetermined logical S-BCCH subchannel, and contains information elements such as (a) message overviews or summaries for each cell broadcast message, (b) information concerning emergency messages, (c) information concerning the language used in different broadcast messages, (d) an alphanumeric broadcast domain operator name and a specific operator greeting, (e) information concerning changes in broadcast messages, and (f) information concerning subchannels.
