Service capability server / EPC coordination for power savings mode and paging
The present application is directed to one or more aspects with at least one aspect describing a method including a step of receiving device context information including a Power Saving Mode (PSM) Sync Flag from a core network node, where the PSM Sync Flag indicates a monitoring type of a device from among plural devices in the network. The method also includes a step of receiving a tracking area update or an attach request from the device on the network. The method further includes a step of sending a device availability notification request to a core network interworking function.
1. A method comprising:
receiving, at a core network node, a message including an indication that a notification is to be provided when a device becomes available to receive data and information indicative of one or more servers to be notified when the device becomes available to receive data;
receiving an area update or an attach request from the device; and
sending a device availability notification to a core network function, wherein the device availability notification comprises the information and a periodic area update time value.
2. The method of claim 1 , wherein the device availability notification includes further information selected from any one or more of an identification of the device, an address list of service capability servers, an active time value or a cause for the device availability notification.
3. The method of claim 1 , wherein the device availability notification provides notification information when the device exits a power saving mode.
4. The method of claim 1 , wherein the message includes subscription information.
5. The method of claim 1 , wherein the message includes a request or notification.
6. The method of claim 1 , wherein the core network function is a core network interworking function.
7. The method of claim 1 , wherein the core network function is a core network interworking function.
8. A method comprising
receiving, at a core network function via a server, a message including an indication that a notification is to be provided when a device becomes available to receive data;
receiving, at the core network function via a network apparatus, a device availability notification for the device, wherein the device availability notification comprises information indicative of one or more servers to be notified by the core network function and a periodic area update time value; and
sending, from the core network function to the server, a second device availability notification for the device, wherein the second device availability notification comprises information including the periodic area update time value.
9. The method of claim 8 , wherein the first and second device availability notifications include further information selected from any one or more of an identification of the device, an address list of service capability servers, an active time value or a cause for the device availability notification.
10. The method of claim 8 , wherein the first device availability notification provides notification information when the device exits a power savings mode.
11. The method of claim 8 , wherein the core network function is a core network interworking function.
12. An apparatus comprising:
a non-transitory memory including stored instructions; and
a processor operably coupled to the non-transitory memory, and configured to execute the stored instructions including:
receiving, at a core network function from a server, a message including an indication that a notification is to be provided when a device becomes available to receive data;
receiving, at the core network function from a network apparatus, a device availability notification for the device, wherein the device availability notification comprises information and a periodic area update time value; and
sending, from the core network function to the server, a second device availability notification for the device, wherein the second device availability notification comprises information including the periodic area update time value.
13. The apparatus of claim 12 , wherein the processor is further configured to:
receive, at the core network function, a request to update a power mode characteristic of the device; and
send, from the core network function to the server, an acknowledgement the power mode characteristic has been updated.
14. The apparatus of claim 12 , wherein the processor is further configured to:
forward, from the core network function, an insert subscriber data request to the network apparatus; and
receive, at the core network function, an insert subscriber data answer,
wherein the periodic area update time value is determined based upon the insert subscriber data request.
15. The apparatus of claim 12 , wherein the core network function is a core network interworking function.
16. An apparatus comprising:
a non-transitory memory including stored instructions; and
a processor operably coupled to the non-transitory memory, and configured to execute the stored instructions including:
receiving, at a core network node, a message including an indication that a notification is to be provided when a device becomes available to receive data and information indicative of one or more servers to be notified when the device becomes available to receive data;
receiving an area update or an attach request from the device; and
sending a device availability notification to a core network function, wherein the device availability notification comprises the information and a periodic area update time value.
17. The apparatus of claim 16 , wherein the device availability notification includes further information selected from any one or more of an identification of the device, an address list of service capability servers, an active time value or a cause for the device availability notification.
18. The apparatus of claim 16 , wherein the device availability notification provides notification information when the device exits a power saving mode.
19. The apparatus of claim 16 , wherein the message includes subscription information.
20. The apparatus of claim 16 , wherein the message includes a request or notification.
21. The apparatus of claim 16 , wherein the core network function is a core network interworking function.
