A method and a system for providing signaling in cellular telephone system providing broadcast services to fully integrate broadcast services with the services provided by the cellular telephone systems. The signaling method coordinate interaction between an access network and the subscriber station to allowing the subscriber station to decode the broadcast service, to receive paging messages while receiving the broadcast service, to properly transition between operation states, and other functions known to one of ordinary skill in the art.

What is claimed is: 1. A method for use in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, the method comprising: receiving at each subscriber station in an idle state a message broadcast on an overhead channel normally used for the dedicated communications service, the message containing broadcast parameters for sessions of a high speed broadcast service (HSBS), wherein at least a portion of the plurality of subscriber stations are subscribed to the HSBS; decoding at each subscriber station a header of the message; and decoding a remainder of the message only at subscriber stations subscribed to the HSBS. 2. The method as claimed in claim 1, further comprising receiving, by a subscriber station subscribed to the HSBS and engaged in a call on a dedicated channel, another message containing broadcast parameters and transmitted on the dedicated channel. 3. The method as claimed in claim 1, wherein if a subscriber station subscribed to the HSBS is engaged in a call on a dedicated channel, the subscriber station continues to use broadcast parameters previously received in the idle state. 4. The method as claimed in claim 1, wherein the wireless communication system is a CDMA-based system. 5. The method as claimed in claim 1, wherein the HSBS and the dedicated cellular communications service are provided on shared channels. 6. A method for transmitting broadcast parameters for a high speed broadcasting service (HSBS) in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, comprising the steps of: broadcasting from a sector a message containing broadcast parameters for sessions of the HSBS, over an idle state overhead channel normally used for the dedicated communications service by the plurality of subscriber stations, the message containing a header and a remaining portion whereby all subscriber stations of the wireless communication system can decode the header while only subscriber stations subscribed to the HSBS can decode the remaining portion of the message. 7. The method as claimed in claim 6, further comprising transmitting, in a dedicated manner to a subscriber station that is subscribed to the HSBS and engaged in a call on a dedicated channel, another message containing the broadcast parameters for the HSBS, wherein the transmission is performed over the dedicated channel. 8. The method as claimed in claim 6, wherein the HSBS and the dedicated cellular communications service are provided on shared channels. 9. A method for use in a subscriber station that is configured for use in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, the method comprising: receiving, in an idle state, a broadcast message over an overhead channel normally used for the dedicated communications service, the message containing broadcast parameters for sessions of a high speed broadcast service (HSBS), wherein at least a portion of the subscriber stations are subscribed to the HSBS; decoding a header of the message regardless of whether the subscriber station is subscribed to the HSBS; and decoding a remainder of the message only if the subscriber station is subscribed to the HSBS. 10. The method as claimed in claim 9, further comprising: receiving, if the subscriber station is subscribed to the HSBS and engaged in a call on a dedicated channel, another message containing the broadcast parameters transmitted on the dedicated channel. 11. The method as claimed in claim 9, further comprising using, if the subscriber station is subscribed to the HSBS and engaged in a call on a dedicated channel, the broadcast parameters previously received in the idle state. 12. The method as claimed in claim 9, wherein the HSBS and the dedicated cellular communications service are provided on shared channels. 13. The method as claimed in claim 9, wherein the wireless communications system is a CDMA-based system. 14. A computer-readable medium for using in a subscriber station in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, wherein at least a portion of the subscriber stations are subscribed to a high speed broadcast service (HSBS), the computer-readable medium comprising: decoding a header of a message containing broadcast parameters for sessions of the HSBS, the decoding being performed regardless of whether the subscriber station is subscribed to the HSBS; and decoding a remainder of the message only if the subscriber station is subscribed to the HSBS. 15. The computer-readable medium as claimed in claim 14, wherein the HSBS and the dedicated cellular communications service are provided on shared channels. 16. The subscriber station apparatus as claimed in claim 14, wherein the HSBS and the dedicated cellular communications service are provided on shared channels. 17. A subscriber station apparatus for use in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, wherein at least a portion of the subscriber stations are subscribed to a high speed broadcast service (HSBS), the subscriber station apparatus comprising: a memory that retains instructions related to: decoding a header of a message containing broadcast parameters for sessions of the HSBS, the decoding being performed regardless of whether the subscriber station is subscribed to the HSBS; and decoding a remainder of the message only if the subscriber station is subscribed to the HSBS; and a processor, coupled to the memory, configured to execute the instructions retained in memory. 18. A subscriber station apparatus for use in a wireless communications system that provides dedicated cellular communications service to a plurality of subscriber stations, the apparatus comprising: means for receiving, in an idle state, a message broadcasted over an overhead channel normally used for the dedicated communications service, the message containing broadcast parameters for sessions of a high speed broadcast service (HSBS) wherein at least a portion of the plurality of subscriber stations are subscribed to the HSBS; means for decoding a header of the message regardless of whether the subscriber station is subscribed to the HSBS; and means for decoding a remainder of the message only if the subscriber station is subscribed to the HSBS. 19. The subscriber station apparatus as claimed in claim 18, wherein the HSBS and the dedicated cellular communications service are provided on shared channels.
