Abstract

A wireless communications network (120) responds to each incoming call placed to a wireless communications device (134) by transmitting a call-paging message (418) within a corresponding partition of a digital radio frame of prescribed format. Responsive to each occurrence of a broadcast event (404), the network transmits (414) a repeating broadcast-paging message announcing the availability of broadcast content from the network. The broadcast-paging message is transmitted multiple times within each digital radio frame. Another sequence (500) describes WCD operation in this network. Responsive to wakeup (502) from sleep, the WCD detects (509) received signal quality. The WCD also receives (510) scheduled network transmission of a call-paging message and a number of instances (at least one) of a repeating network transmitted broadcast-paging message that occurs multiple times for each scheduled transmission of the call-paging message. This number varies inversely with the detected signal quality.

Claims

1. A method for communicating paging messages to wireless communications devices of a wireless communications network, where the network responds to each incoming call placed to a wireless communications device by transmitting a call-paging message within a corresponding partition of a digital radio frame of prescribed format, the method comprising operations of:

responsive to each occurrence of a specified broadcast event;

transmitting a repeating broadcast-paging message announcing the availability of broadcast content from the network, and

transmitting the broadcast-paging message multiple times within each digital radio frame; and

responsive to each occurrence of a first broadcast event associated with a first set of one or more broadcast programs, transmitting a first repeating broadcast-paging message announcing the availability of broadcast content related to the first set of broadcast programs.

2. The method of claim 1, further comprising:

responsive to each occurrence of a second broadcast event associated with second set of one or more broadcast programs, transmitting a second repeating broadcast-paging message announcing the availability of broadcast content related to the second set of broadcast programs.

3. The method of claim 1, wherein the broadcast-paging message comprises a binary signal indicating whether or not broadcast content is available from the network.

4. The method of claim 1, wherein one type of broadcast event comprises base station receipt of network-assigned instructions to notify wireless communication devices of one or more particular broadcast programs.

5. The method of claim 1, wherein one type of broadcast event comprises the base station upon querying the network learning that one or more unannounced broadcast programs are available from the network.

6. The method of claim 1, wherein one type of broadcast event comprises the base station upon querying the network learning that the network has designated one or more previously announced broadcast programs for re-announcement.

7. A non-transitory computer-readable medium tangibly embodying a program of machine-readable instructions executable by a digital data processor to perform operations for communicating paging messages to wireless communications devices of a wireless communications network, where the network responds to each incoming call placed to a wireless communications device by transmitting a call-paging message within a corresponding partition of a digital radio frame of prescribed format, the method including operations of:

responsive to each occurrence of a broadcast event,

transmitting a repeating broadcast-paging message announcing the availability of broadcast content from the network, and

transmitting the broadcast-paging message multiple times within each digital radio frame; and

responsive to each occurrence of a first broadcast event associated with a first set of one or more broadcast programs, transmitting a first repeating broadcast-paging message announcing the availability of broadcast content related to the first set of broadcast programs.

8. The non-transitory computer-readable medium of claim 7, further comprising:

responsive to each occurrence of a second broadcast event associated with second set of one or more broadcast programs, transmitting a second repeating broadcast-paging message announcing the availability of broadcast content related to the second set of broadcast programs.

9. The non-transitory computer-readable medium of claim 7, wherein the broadcast-paging message comprises a binary signal indicating whether or not broadcast content is available from the network.

10. The non-transitory computer-readable medium of claim 7, wherein the broadcast event comprises at least one broadcast event type selected from a group of broadcast event types comprising:

base station receipt of network-assigned instructions to notify wireless communication devices of one or more particular broadcast programs;

the base station, upon querying the network, learning that one or more unannounced broadcast programs are available from the network; and

the base station, upon querying the network, learning that the network has designated one or more previously announced broadcast programs for re-announcement.

11. Circuitry comprising:

multiple interconnected electrically conductive elements configured to perform operations for communicating paging messages to wireless communications devices of a wireless communications network, where the network responds to each incoming call placed to a wireless communications device by transmitting a call-paging message within a corresponding partition of a digital radio frame of prescribed format, the method including operations of;

responsive to each occurrence of a broadcast event,

transmitting a repeating broadcast-paging message announcing the availability of broadcast content from the network, and

transmitting the broadcast-paging message multiple times within each digital radio frame; and

responsive to each occurrence of a first broadcast event associated with a first set of one or more broadcast programs, transmitting a first repeating broadcast-paging message announcing the availability of broadcast content related to the first set of broadcast programs.

12. The circuitry of claim 11, further comprising;

responsive to each occurrence of a second broadcast event associated with second set of one or more broadcast programs, transmitting a second repeating broadcast-paging message announcing the availability of broadcast content related to the second set of broadcast programs.

13. The circuitry of claim 11, wherein the broadcast-paging message comprises a binary signal indicating whether or not broadcast content is available from the network.
