Abstract

A device may determine to page a machine device. The device may determine a coverage level value associated with the machine device. The coverage level value may indicate a network condition in an area in which the machine device has been deployed. The device may determine, based on the coverage level value, a quantity of pages to be transmitted for the machine device. The device may determine, based on the coverage level value and the quantity of pages, one or more frequency ranges to be used to transmit one or more pages. The device may transmit the one or more pages using the one or more frequency ranges.

Claims (84)

1. A base station, comprising:

one or more processors to:

receive a signal from a device to trigger a page of a machine device;

determine, based on receiving the signal, the device that triggered the page;

determine, based on determining the device that triggered the page, a coverage level value associated with the machine device,

the coverage level value indicating a network condition in an area in which the machine device has been deployed;

determine, based on the coverage level value, a quantity of pages to be transmitted for the machine device;

select, based on the coverage level value and the quantity of pages, one or more frequency ranges to be used to transmit one or more pages; and

transmit the one or more pages using the one or more frequency ranges.

2. The base station of claim 1 , where the one or more processors, when determining the device that triggered the page, are to:

determine whether the page was triggered by the base station or another device different from the base station.

3. The base station of claim 1 , where the one or more processors, when determining the device that triggered the page, are to:

determine that the base station triggered the page; and

where the one or more processors, when determining the coverage level value, are to:

use a first value for the coverage level value based on determining that the base station triggered the page,

the first value indicating a worse network condition associated with the machine device than a second value.

4. The base station of claim 1 , where the one or more processors, when determining the coverage level value, are to:

determine the coverage level value based on a first coverage level value, stored by the base station, and a second coverage level value received from a network device other than the base station and the machine device.

5. The base station of claim 1 , where the one or more processors, when determining the coverage level value, are to:

determine the coverage level value based on one or more network coverage parameters associated with the machine device.

6. The base station of claim 1 , where the one or more processors, when determining the coverage level value, are to:

determine the coverage level value based on an average network condition,

the average network condition being based on information reported by the machine device.

7. The base station of claim 1 , where the one or more processors, when selecting the one or more frequency ranges, cause the one or more processors to:

select the one or more frequency ranges based on a system frame number and a device identifier that identifies the machine device.

8. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by one or more processors, cause the one or more processors to:

receive a signal to trigger a page of a machine device;

determine, based on receiving the signal, a coverage level value associated with the machine device,

the coverage level value being based on a network condition reported by the machine device;

determine, based on the coverage level value, a first quantity of pages to be transmitted for the machine device,

a second quantity of pages transmitted for the machine device being less than or equal to the first quantity of pages;

select, based on the coverage level value and the first quantity of pages, a set of frequency ranges to be used to transmit one or more pages; and

transmit the one or more pages using the set of frequency ranges.

9. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, that cause the one or more processors to determine the set of frequency ranges, cause the one or more processors to:

determine the set of frequency ranges based on a bandwidth of a resource block associated with a network via which the machine device communicates.

10. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, that cause the one or more processors to determine the set of frequency ranges, cause the one or more processors to:

determine the set of frequency ranges based on a system frame number and a device identifier that identifies the machine device.

11. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, that cause the one or more processors to determine the set of frequency ranges, cause the one or more processors to:

determine a smaller quantity of frequency ranges when the coverage level value indicates a first network condition, or

determine a larger quantity of frequency ranges when the coverage level value indicates a second network condition,

the second network condition being a worse network condition than the first network condition.

12. The non-transitory computer-readable medium of claim 8 , where the set of frequency ranges is a first set of frequency ranges; and

where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:

determine that a connection request has not been received from the machine device after transmitting the one or more pages;

modify the coverage level value to form a modified coverage level value that indicates a worse network condition than the coverage level value;

determine a second set of frequency ranges based on the modified coverage level value,

transmit at least one page using the second set of frequency ranges.

13. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:

determine that the coverage level value satisfies a threshold; and

stop transmitting pages for the machine device based on determining that the coverage level value satisfies the threshold.

14. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, that cause the one or more processors to determine the coverage level value, are to:

determine the coverage level value based on an average network condition,

15. A method, comprising:

receiving, by a base station, a signal from a device to trigger a page of a machine device;

determining, by the base station and based on receiving the signal, a coverage level value associated with the machine device,

the coverage level value indicating a network condition reported by the machine device;

determining, by the base station and based on the coverage level value, a threshold quantity of pages to be transmitted for the machine device;
