Abstract

The invention is directed to reducing paging overhead in a network. An exemplary method comprises: determining whether a user equipment (UE) is substantially stationary, wherein the UE is located in a first network cell associated with a network; in response to determining the UE is substantially stationary, transmitting an indicator to the network; determining whether the UE moves from the first network cell to a second network cell; and in response to determining the UE moves from the first network cell to the second network cell, transmitting updated location information associated with the UE to the network.

First claim

What is claimed is:

1. A method for reducing paging overhead in a network, the method comprising:
determining that a user equipment (UE) will remain substantially stationary for a period of time, wherein the UE is located in a first network cell associated with the network; and
in response to determining the UE will remain substantially stationary for a period of time, transmitting, from the UE, an indicator to the network, wherein the indicator indicates that the UE is substantially stationary and, wherein the network responds to the indicator by transmitting a paging signal to the first network cell without transmitting the paging signal to one or more other network cells that are part of a same geographic tracking area as the first network cell.

2. The method of claim 1 , further comprising determining whether the UE moves from the first network cell to a second network cell.

3. The method of claim 2 , wherein determining whether the UE moves from the first network cell to the second network cell comprises periodically determining whether the UE moves from the first network cell to the second network cell.

4. The method of claim 2 , wherein determining whether the UE moves from the first network cell to the second network cell comprises determining, by the UE, whether the UE moves from the first network cell to the second network cell.

5. The method of claim 2 , wherein determining whether the UE moves from the first network cell to the second network cell comprises determining, by the network, whether the UE moves from the first network cell to the second network cell.

6. The method of claim 2 , further comprising, in response to determining that the UE moves from the first network cell to the second network cell, transmitting updated location information associated with the UE to the network.

7. The method of claim 6 , wherein the network transmits a paging signal to the first network cell and the second network cell when the UE moves from the first network cell to the second network cell.

8. The method of claim 1 , wherein the network comprises a network backbone.

9. The method of claim 1 , wherein the UE is substantially stationary if the UE is not moving or has limited movement.

10. The method of claim 1 , wherein the second network cell is associated with the same or different geographical area when compared to the first network cell.

11. The method of claim 1 , further comprising:
determining whether the UE moves from the first network cell to a third network cell, wherein the third network cell is not associated with a different geographical area from the first network cell; and
in response to determining the UE moves from the first network cell to the third network cell, not transmitting updated location information associated with the UE to the network.

12. The method of claim 1 , wherein the network is associated with the 3 rd Generation Partnership Project (3GPP).

13. The method of claim 1 , wherein the UE comprises a mobile device.

14. A method for reducing paging overhead in a network, the method comprising:
receiving, by the network, an indicator from a user equipment (UE), wherein the indicator is transmitted by the UE in response to determining that the UE will remain substantially stationary for a period of time and indicates the UE is substantially stationary within a first network cell associated with the network; and
in response to receiving the indicator, transmitting a paging signal to the first network cell without transmitting the paging signal to one or more other network cells that are part of a same geographic tracking area as the first network cell.

15. The method of claim 14 , further comprising receiving updated location information from the UE, wherein the updated location information indicates that the UE has moved from the first network cell to a second network cell.

16. The method of claim 15 , further comprising, in response to determining the UE has moved from the first network cell to the second network cell, transmitting the paging signal to the first network cell and the second network cell.

17. A system for reducing paging overhead in a network, the system comprising:
a user equipment located in a first network cell of the network; and
a base station configured to (i) receive an indicator from the user equipment (UE) that is transmitted in response to determining that the UE will remain substantially stationary for a period of time and indicates the UE is substantially stationary, and (ii) in response to receiving the indicator, transmit a paging signal to the first network cell without transmitting the paging signal to one or more other network cells that are part of a same geographic tracking area as the first network cell.
