Abstract

A computer device may include a processor configured to detect a condition to page a user equipment (UE) device, retrieve mobility category information associated with the UE device from a mobility database, and use the retrieved mobility category information to determine a paging policy. The computer device may be further configured to select a number of base station cells to which the computer device is to send a paging message based on the determined paging policy and page the UE device using the selected number of base station cells.

First claim

What is claimed is:

1. A method comprising:
detecting, by a computer device, a condition to page a user equipment (UE) device;
selecting, by the computer device, to page a first number of base station cells located around, and within a particular diameter of, a last known base station cell servicing the UE device, when the UE device is associated with a low mobility category;
selecting, by the computer device, to page a second number of base station cells located around, and within the particular diameter of, the last known base station cell servicing the UE device, wherein the second number is higher than the first number, when the UE device is associated with a high mobility category; and
paging, by the computer device, the UE device using the selected number of base station cells.

2. The method of claim 1 , further comprising:
storing a paging table that includes paging policies for particular mobility categories;
retrieving mobility category information for the UE device from a mobility database; and
determining a paging policy based on the retrieved mobility category information for the UE device and the stored paging table.

3. The method of claim 1 , further comprising:
registering the UE device with a subscriber profile management device;
receiving information identifying a mobility category based on an intended usage of the UE device;
storing the received information identifying the mobility category in a subscriber profile associated with the UE device; and
providing the information identifying the mobility category to the computer device.

4. The method of claim 3 , wherein the computer device includes a Mobility Management Entity (MME) device and wherein the subscriber profile management device includes a Home Subscriber Server (HSS) device.

5. The method of claim 3 , wherein the computer device includes an Access and Mobility Management Function (AMF) device and wherein the subscriber profile management device includes a Unified Data Management (UDM) device.

6. The method of claim 1 , further comprising:
detecting another condition to page another UE device;
determining mobility category information for the other UE device, wherein the determined mobility category information identifies that the other UE device is associated with a stationary mobility category; and
selecting to page only a last known base station cell servicing the other UE device, based on the determined mobility category information identifying that the other UE device is associated with the stationary mobility category.

7. The method of claim 1 , further comprising:
detecting another condition to page another UE device;
determining mobility category information for the other UE device, wherein the determined mobility category information identifies that the other UE device is associated with a variable mobility category; and
selecting a default paging procedure, based on the determined mobility category information identifying that the other UE device is associated with the variable mobility category.

8. The method of claim 1 , further comprising:
monitoring a mobility associated with the UE device;
generating a mobility index for the UE device based on the monitored mobility;
comparing the generated mobility index to a mobility category associated with the UE device based on mobility category information associated with the UE device in a mobility database; and
generating an alert if the mobility index differs from the mobility category.

9. A device comprising:
a processor configured to:
detect a condition to page a user equipment (UE) device;
select to page a first number of base station cells located around, and within a particular diameter of, a last known base station cell servicing the UE device, when the UE device is associated with a first mobility category;
select to page a second number of base station cells located around, and within the particular diameter of, the last known base station cell servicing the UE device, wherein the second number is higher than the first number, when the UE device is associated with a second mobility category; and
page the UE device using the selected number of base station cells.

10. The device of claim 9 , wherein the processor is further configured to:
store a paging table that includes paging policies for particular mobility categories;
retrieve mobility category information for the UE device from a mobility database; and
determine a paging policy based on the retrieved mobility category information for the UE device and the stored paging table.

11. The device of claim 9 , wherein the processor is further configured to:
register the UE device with a subscriber profile management device;
receive information identifying a mobility category based on an intended usage of the UE device; and
store the received information identifying the mobility category in a subscriber profile associated with the UE device.

12. The device of claim 11 , wherein the device includes a Mobility Management Entity (MME) device and wherein the subscriber profile management device includes a Home Subscriber Server (HSS) device.

13. The device of claim 11 , wherein the device includes an Access and Mobility Management Function (AMF) device and wherein the subscriber profile management device includes a Unified Data Management (UDM) device.

14. The device of claim 9 , wherein the processor is further configured to:
detect another condition to page another UE device;
determine mobility category information for the other UE device, wherein the determined mobility category information identifies that the other UE device is associated with a stationary mobility category; and
select to page only a last known base station cell servicing the other UE device, based on the determined mobility category information identifying that the other UE device is associated with the stationary mobility category.

15. The device of claim 9 , wherein the processor is further configured to:
detect another condition to page another UE device;
determine mobility category information for the other UE device, wherein the determined mobility category information identifies that the other UE device is associated with a variable mobility category; and
select a default paging procedure, based on the determined mobility category information identifying that the other UE device is associated with the variable mobility category.

16. The device of claim 9 , wherein the processor is further configured to:
monitor a mobility associated with the UE device;
generate a mobility index for the UE device based on the monitored mobility;
compare the generated mobility index to a mobility category associated with the UE device based on mobility category information associated with the UE device in a mobility database; and
generate an alert if the mobility index differs from the mobility category.

17. A system comprising:
a subscriber profile management device configured to:
store mobility category information for a user equipment (UE) device; and

a computer device configured to:
detect a condition to page the UE device;
obtain the stored mobility category information from the subscriber profile management device;
select to page a first number of base station cells located around, and within a particular diameter of, a last known base station cell servicing the UE device, when the stored mobility category information indicates that the UE device is associated with a first mobility category;
select to page a second number of base station cells located
