The apparatus of claim 1, wherein the means for receiving said one or more bits on said modified quick paging channel comprises means for demodulating an uncoded, on-off keying modulated direct sequence spread spectrum signal. 3. An apparatus for transmitting broadcast messages in a spread spectrum telecommunications system comprising: a) means for determining prior to the beginning of a first time slot the categories of the broadcast messages that will be transmitted during said first time slot; b) means for determining one or more bit indices to be associated with a broadcast indicator bit stream of a pre-determined length based upon said determined categories of the broadcast messages; c) means for generating said broadcast indicator bit stream wherein bits located at said bit indices are set to an on value, and wherein all other bits in said broadcast indicator bit stream are set to an off value; d) means for transmitting said broadcast indicator bit stream on a first channel during a second time slot that occurs prior to said first time slot, wherein said second time slot precedes said first time slot by a pre-determined time interval; and e) means for transmitting during said first time slot an encoded bit stream that contains one or more broadcast pointers corresponding to said categories of the broadcast messages. 4. The apparatus of claim 3, wherein the means for determining the one or more bit indices further comprises means for hashing said categories of the broadcast messages via a pre-determined hashing function to determine said one or more bit indices. 5.
