Abstract

A radio network node receives a page request from a core network node. The page request indicates to page a wireless communication device. The radio network node determines a next occurrence of a monitoring window during which the wireless communication device will monitor a paging channel associated with the radio network node. If the amount of time until the next occurrence of the monitoring window exceeds an amount of time that the radio network node can store the page request, the radio network node discards the page request and sends a response to the core network node indicating that the page request was discarded; the response includes a paging timer value that indicates when the core network node should repeat the page request.

Claims

1. A wireless communication device comprising one or more processors and memory, the memory containing instructions executable by the one or more processors, whereby the wireless commuication device is operable to:

monitor a paging channel associated with a radio network node according to a non-extended monitoring window operation and a long paging cycle;

receive a paging congestion indicator from the radio network node, wherein the paging congestion indicator is included in a paging message that the wireless communication device receives from the radio network node; and

in response to receiving the paging congestion indicator, perform at least one of;

switching from the non-extended monitoring window operation to an extended monitoring window operation; and

switching from the long paging cycle to a legacy paging cycle.

2. The wireless communication device of claim 1, wherein the extended monitoring window operation comprises monitoring the paging channel according to an extended monitoring window comprising a number X of early paging blocks before a nominal paging block associated with the wireless communication device.

3. The wireless communication device of claim 1, further operable to determine to enable the extended monitoring window operation via one of the following:

through an indication in system information from a radio access network, as a part of a registration procedure, or by determining that the wireless communication device is using the long paging cycle.

4. The wireless communication device of claim 1, further operable to communicate an extended monitoring window indicator to a core network node to inform the core network node that the wireless communication device is capable of using an extended monitoring window, wherein the extended monitoring window indicator indicates additional paging blocks of the extended monitoring window.

5. The wireless communication device of claim 4, further operable to communicate to the core network node an extended monitoring window timer associated with the extended monitoring window indicator, wherein the extended monitoring window timer specifies a time period for which the wireless communication device uses the extended monitoring window.

6. The wireless communication device of claim 1, wherein

the legacy paging cycle corresponds to a paging cycle supported by specification 3GPP TS 44.018 version 12.1.0;

and

the long paging cycle corresponds to a paging cycle longer than what is supported by specification 3GPP TS 44.018 version 12.1.0.

7. A method in a wireless communication device, comprising:

monitoring a paging channel associated with a radio network node according to a non-extended monitoring window operation and a long paging cycle;

receiving a paging congestion indicator from the radio network node, wherein the paging congestion indicator is included in a paging message that the wireless communication device receives from the radio network node; and

in response to receiving the paging congestion indicator, perform at least one of;

switching from the non-extended monitoring window operation to an extended monitoring window operation; and

switching from the long paging cycle to a legacy paging cycle.

8. The method of claim 7, wherein the extended monitoring window operation comprises monitoring the paging channel according to an extended monitoring window comprising a number X of early paging blocks before a nominal paging block associated with the wireless communication device.

9. The method of claim 7, further comprising determining to enable the extended monitoring window operation via one of the following:

through an indication in system information from a radio access network, as a part of a registration procedure, or by determining that the wireless communication device is using the long paging cycle.

10. The method of claim 7, further comprising communicating an extended monitoring window indicator to a core network node to inform the core network node that the wireless communication device is capable of using an extended monitoring window, wherein the extended monitoring window indicator indicates additional paging blocks of the extended monitoring window.

11. The method of claim 10, further comprising communicating to the core network node an extended monitoring window timer associated with the extended monitoring window indicator, wherein the extended monitoring window timer specifies a time period for which the wireless communication device uses the extended monitoring window.

12. The method of claim 7, wherein

the legacy paging cycle corresponds to a paging cycle supported by specification 3GPP TS 44.018 version 12.1.0;

and

the long paging cycle corresponds to a paging cycle longer than what is supported by specification 3GPP TS 44.018 version 12.1.0.
