Abstract
A relatively large short message (BC-SMS) is broadcast to a selected group of mobile subscriber stations within a cellular radio system. Each BC-SMS message greater in size than a predetermined number of octets is divided into segments, formatted into a separate modified paging message (PBC) which is unrecognizable to existing mobiles but recognizable to new mobiles. The BC-SMS message segments are broadcast in sequence as modified paging messages to the mobiles within the region of the system where the selected group is believed to be operating. Each paging message includes the essential elements of a paging message, a message ID number, a sequence number and the message segment payload.
