Abstract

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.

Claims

1. A method for a subscriber station registration in a broadcast communication system, comprising:

receiving a HSBS channel modulating a first frequency; and

monitoring a timer status for the HSBS channel, and if the timer status is expired;

performing a broadcast service registration with a sector transmitting the HSBS channel;

setting status of the timer for the HSBS channel to enabled; and

starting a timer for the HSBS channel.

2. The method as claimed in claim 1, wherein performing a broadcast service registration with a sector transmitting the HSBS channel further comprises:

transmitting a paging identifier to the sector.

3. The method as claimed in claim 2, wherein transmitting a paging identifier to the sector further comprises:

transmitting an identifier of the HSBS channel monitored by the subscriber station to the sector.

4. The method as claimed in claim 2, wherein transmitting a paging identifier to the sector further comprises:

transmitting an identifier of the frequency monitored by the subscriber station to the sector.

5. The method as claimed in claim 1, further comprising setting timer status to expired for all HSBS channels upon power-up of the subscriber station.

6. A method for a subscriber station registration in a broadcast communication system, comprising:

receiving a broadcast service registration from the subscriber station at a sector;

adding a paging identifier to the subscribers'"'"' station paging set; and

starting a timer for the paging identifier.

7. The method as claimed in claim 6, further comprising:

monitoring a timer status of all paging identifiers for all subscriber stations'"'"' paging sets, and if a timer status of a paging identifier for a subscriber station is expired, then removing the paging identifier from the subscriber'"'"'s station paging set.

8. The method as claimed in claim 6, further comprising adding an identifier for the frequency that the subscriber station monitors upon power-up to the subscribers'"'"' station paging set

9. The method as claimed in claim 6, wherein adding a paging identifier to the subscribers'"'"' station paging set comprises:

adding an identifier of the HSBS channel monitored by the subscriber station to the subscribers'"'"' station paging set

10. The method as claimed in claim 6, wherein adding an identifier to the subscribers'"'"' station paging set comprises:

adding an identifier of a frequency modulated by the HSBS channel monitored by the subscriber station to the subscribers'"'"' station paging set

11. A method for paging a subscriber station in a broadcast communication system, comprising:

determining a status of the subscriber station'"'"'s paging set;

determining paging channels on which to page the subscriber station in accordance with the determined status of the subscriber station'"'"'s paging set; and

paging the subscriber station on all determined paging channels.

12. A method for paging a subscriber station in a broadcast communication system, comprising:

modulating all frequencies of a sector with a broadcast channel;

determining paging channels on which to page the subscriber station for each of the frequencies; and

paging the subscriber station on all determined paging channels.

13. A method for paging a subscriber station in a broadcast communication system, comprising:

determining a frequency that the subscriber station monitors upon power-up;

determining all frequencies modulated by broadcast channels;

determining paging channels on which to page the subscriber station for each of the frequencies; and

paging the subscriber station on all determined paging channels.

14. A method for paging a subscriber station in a broadcast communication system, comprising:

determining a frequency that the subscriber station monitors upon power-up, and if at least one broadcast channel is transmitted, then;

determining all frequencies modulated by the at least one broadcast channels to which the subscriber station is subscribed;

determining paging channels on which to page the subscriber station for each of the frequencies; and

paging the subscriber station on all determined paging channels.

15. The method as claimed in claim 14, further comprising:

determining paging channel on which to page the subscriber station for a frequency that the subscriber station monitors upon power-up; and

paging the subscriber station on the determined paging channel if no broadcast channel is transmitted.
