Abstract

Systems, methods, and software for wireless frequency changes for wireless communication devices based on tracking area updates in wireless communication systems are provided herein. In one example, a method of operating a communication system is provided. The method includes providing wireless access to communication services for wireless communication devices over a first frequency spectrum at a wireless access node, and receiving tracking area updates transferred by ones of the wireless communication devices. The method also includes processing at least a quantity of the tracking area updates received at the wireless access node to determine idle timers for the wireless communication devices, where an expiration of an associated idle timer indicates that an associated wireless communication device can no longer receive the wireless access over the first frequency spectrum and can receive further wireless access over a second frequency spectrum.

Claims

1. A method of operating a communication system, the method comprising:

providing wireless access to communication services for wireless communication devices over a first frequency spectrum at a wireless access node;

receiving tracking area updates transferred by ones of the wireless communication devices;

identifying a quantity of the tracking area updates received at the wireless access node from the ones of the wireless communication devices;

processing at least the quantity of the tracking area updates to determine idle timers for the wireless communication devices, wherein an expiration of an associated idle timer indicates that an associated wireless communication device can no longer receive the wireless access over the first frequency spectrum and can receive further wireless access over a second frequency spectrum.

2. The method of claim 1, wherein the expiration of the associated idle timer further instructs the wireless access node to cease providing the wireless access to the associated wireless communication device over the first frequency spectrum.

3. The method of claim 1, wherein the tracking area updates each comprise an indication from any of the wireless communication devices responsive to receiving the wireless access and determining to be receiving the wireless access in a tracking area different than a previous wireless access.

4. The method of claim 1, further comprising:

identifying user profiles for the wireless communication devices;

processing the user profiles and the quantity of the tracking area updates received at the wireless access node to determine the idle timers for the wireless communication devices.

5. The method of claim 4, wherein the user profiles indicate a wireless service provider for each of the wireless communication devices;

and

wherein for wireless communication devices associated with a first wireless service provider, a first idle timer value is determined based on the quantity of the tracking area updates and the first wireless service provider, and for wireless communication devices associated with a second wireless service provider, a second idle timer value is determined based on the quantity of the tracking area updates and the second wireless service provider.

6. The method of claim 1, wherein the quantity of tracking area updates are received over the first frequency spectrum, and wherein processing the quantity of the tracking area updates received at the wireless access node to determine the idle timers for the wireless communication devices comprises:

determining a first idle timer value when the quantity of tracking area updates falls below a first threshold and assigning the first idle timer value as the idle timers; and

determining a second idle timer value when the quantity of tracking area updates exceeds the first threshold and assigning the second idle timer value as the idle timers.

7. The method of claim 6, wherein the first idle timer value is greater than the second idle timer value.

8. The method of claim 1, wherein the first frequency spectrum comprises a first cellular frequency spectrum and the second frequency spectrum comprises a second cellular frequency spectrum different than the first cellular frequency spectrum.

9. The method of claim 1, wherein the wireless access node comprises a first Long Term Evolution (LTE) eNodeB which provides the wireless access over the first frequency spectrum comprising a first LTE cellular frequency spectrum and a second LTE eNodeB which provides the further wireless access over the second frequency spectrum comprising a second LTE cellular frequency spectrum.

10. The method of claim 1, wherein the idle timers comprise subscriber profile identifier (SPID) timers.

11. A communication system, comprising:

a wireless access node configured to provide wireless access to communication services for wireless communication devices over a first frequency spectrum, and receive tracking area updates transferred by ones of the wireless communication devices;

a processing node configured to identify a quantity of the tracking area updates received at the wireless access node from the ones of the wireless communication devices;

the processing node configured to process at least a quantity of the tracking area updates to determine idle timers for the wireless communication devices, wherein an expiration of an associated idle timer indicates that an associated wireless communication device can no longer receive the wireless access over the first frequency spectrum and can receive further wireless access over a second frequency spectrum.

12. The communication system of claim 11, wherein the expiration of the associated idle timer further instructs the wireless access node to cease providing the wireless access to the associated wireless communication device over the first frequency spectrum.

13. The communication system of claim 11, wherein the tracking area updates each comprise an indication from any of the wireless communication devices responsive to receiving the wireless access and determining to be receiving the wireless access in a tracking area different than a previous wireless access.

14. The communication system of claim 11, comprising:

the processing node configured to identify user profiles for the wireless communication devices and process the user profiles and the quantity of the tracking area updates received at the wireless access node to determine the idle timers for the wireless communication devices.

15. The communication system of claim 14, wherein the user profiles indicate a wireless service provider for each of the wireless communication devices;

and

wherein for wireless communication devices associated with a first wireless service provider, the processing node is configured to determine a first idle timer value based on the quantity of the tracking area updates and the first wireless service provider, and for wireless communication devices associated with a second wireless service provider, the processing node is configured to determine a second idle timer value based on the quantity of the tracking area updates and the second wireless service provider.

16. The communication system of claim 11, wherein the quantity of tracking area updates are received over the first frequency spectrum;

and

wherein the processing node is configured to determine a first idle timer value when the quantity of tracking area updates falls below a first threshold and assign the first idle timer value as the idle timers; and

wherein the processing node is configured to determine a second idle timer value when the quantity of tracking area updates exceeds the first threshold and assign the second idle timer value as the idle timers.

17. The communication system of claim 16, wherein the first idle timer value is greater than the second idle timer value.

18. The communication system of claim 11, wherein the first frequency spectrum comprises a first cellular frequency spectrum and the second frequency spectrum comprises a second cellular frequency spectrum different than the first cellular frequency spectrum.

19. The communication system of claim 11, wherein the wireless access node comprises a first Long Term Evolution (LTE) eNodeB which provides the wireless access over the first frequency spectrum comprising a first LTE cellular frequency spectrum and a second LTE eNodeB which provides the further wireless access over the second frequency spectrum comprising a second LTE cellular frequency spectrum.

20. The communication system of claim 11, wherein the idle timers comprise subscriber profile identifier (SPID) timers.
