Abstract

A method and system are provided that allow a mobile communications service provider to broadcast messages using more than one broadcast channel protocol, such that only the mobile stations designed to receive broadcast messages transmitted under each protocol are woken up to monitor their respective broadcast channel slots, thus saving battery life in mobile stations designed to receive broadcast messages transmitted using other broadcast channel protocols.

Claims

1. A method for providing broadcast messages, comprising:

transmitting a plurality of first broadcast page slots on a first channel;

transmitting a plurality of second broadcast page slots on a second channel; and

transmitting a plurality of broadcast indicators on a third channel, such that each one of the plurality of broadcast indicators points to only one of the first or second broadcast page slots.

2. The method of claim 1 wherein the plurality of first broadcast page slots on the first channel are shifted with respect to the plurality of second broadcast page slots on the second channel.

3. The method of claim 1 wherein the plurality of first broadcast page slots on the first channel and the plurality of second broadcast page slots on the second channel are transmitted at different broadcast page cycles.

4. The method of claim 3 wherein the different broadcast page cycles are set by assigning different values to the “

B”

parameter in └

t/4┘

mod (B+X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.

5. The method of claim 3 wherein the different broadcast page cycles are set by assigning different values to the “

X”

parameter in └

t/4┘

mod (B+X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.

6. A base station for providing broadcast messages, comprising:

means for transmitting a plurality of first broadcast page slots on a first channel;

means for transmitting a plurality of second broadcast page slots on a second channel; and

means for transmitting a plurality of broadcast indicators on a third channel, wherein each one of plurality of the broadcast indicators points to only one of the first or second broadcast page slots.

7. The base station of claim 6 further including means for shifting the plurality of first broadcast page slots on the first channel with respect to the plurality of second broadcast page slots on the second channel.

8. The base station of claim 6 wherein the plurality of first broadcast page slots on the first channel and the plurality of second broadcast page slots on the second channel are transmitted at different broadcast page cycles.

9. The base station of claim 8 wherein the different broadcast page cycles are set by assigning different values to the “

B”

parameter in └

t/4┘

mod (B+X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.

10. The base station of claim 8 wherein the different broadcast page cycles are set by assigning different values to the “

X”

parameter in └

t/4┘

mod (B+X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.

11. The base station of claim 6 wherein the firs t channel is a forward paging channel (F-PCH).

12. The base station of claim 6 wherein the second channel is a forward common control channel (F-CCCH).

13. The base station of claim 6 wherein the third channel is a forward quick paging channel (F-QPCH).

14. A computer readable medium embodying a method for providing broadcast messages, the method comprising:

transmitting a plurality of first broadcast page slots on a first channel;

transmitting a plurality of second broadcast page slots on a second channel; and

transmitting a plurality of broadcast indicators on a third channel, such that each one of the plurality of the broadcast indicators may point to only one of the first or second broadcast page slots.

15. A base station for providing broadcast messages, comprising:

a transmitter configured to transmit a plurality of first broadcast page slots on a first channel, transmit a plurality of second broadcast page slots on a second channel, and transmit a plurality of broadcast indicators on a third channel; and

a processor configured to control the transmitter such that each one of the plurality of broadcast indicators points to only one of the first or second broadcast page slots.

16. The base station of claim 15 wherein the processor is further configured to shift the plurality of first broadcast page slots on the first channel with respect to the plurality of second broadcast page slots on the second channel.

17. The base station of claim 15 wherein the processor is further configured to control the transmitter to transmit the plurality of first broadcast page slots on the first channel and the plurality of second broadcast page slots on the second channel at different broadcast page cycles.

18. The base station of claim 17 wherein the different broadcast page cycles are set by assigning different values to the “

B”

parameter in └

t/4┘

mod (B+X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.

19. The base station of claim 17 wherein the different broadcast page cycles are set by assigning different values to the “

X”

parameter in └

t/4┘

mod (B +X)=0, where “

t”

stands for a system time and “

X”

stands for another parameter.
