Abstract

Systems, methods, and computer-readable media, for reducing transitions between active and idle states are provided. In some embodiments, transition data indicating transitions between an active state and an idle state associated with a mobile device is received. Thereafter, an idle state pattern that indicates a pattern of an idle state associated with the mobile device is identified. Based on the idle state pattern, an inactivity timer update corresponding with the idle state pattern is provided to at least one communication tower. The inactivity timer update provides a time duration or time duration adjustment to be applied by the at least one communication tower for use in detecting a transition from an active state to an idle state.

First claim

What is claimed is:

1. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon that, when executed, perform a method for facilitating reduction of transitions between active and idle states, the media comprising:
one or more processors configured to:
receive data indicating a mobile device performing transitions between an active state and an idle state, the data received via a communication tower that communicates with the mobile device;
identify, in the data received, an idle state pattern of the mobile device, wherein the idle state pattern is a pattern in the transitions performed by the mobile device and the idle state pattern comprises a time duration of the mobile device remaining in the idle state between transitions regarding the active state, and wherein in the idle state the mobile device does not transmit data to the communication tower;
when the idle state pattern of the mobile device transitioning is identified, trigger deep packet inspection of the data associated with the mobile device; and
provide an inactivity timer update to the communication tower based at least on the deep packet inspection, the inactivity timer update changing a length of a time duration of the inactivity timer of the communication tower to match the idle state pattern of the mobile device, wherein the communication tower uses the inactivity timer update to detect the mobile device performing transitions between an active state and an idle state, and wherein the communication tower does not modify a traffic path of the mobile device before the time duration of the inactivity timer expires, as updated to match the idle state pattern of the mobile device.

2. The media of claim 1 , wherein the data received indicates one or more transitions from an active state to an idle state, from an idle state to an active state, or a combination thereof.

3. The media of claim 1 , wherein the inactivity timer update corresponding with the idle state pattern is provided to more than one communication tower.

4. The media of claim 1 , wherein the method further comprises analyzing, by a management entity that communicates with the communication tower, the data received to identify the idle state pattern of the mobile device.

5. The media of claim 1 , wherein the inactivity timer update equals the time duration of which the mobile device remains idle before transitioning to the active state.

6. The media of claim 1 , wherein the inactivity timer update equals an adjustment applied to the time duration of which the mobile device remains idle before transitioning to the active state.

7. A method for facilitating reduction of transitions between active and idle states, the method comprising:
detecting, by a management entity, a pattern in transitions performed by the specific user device, wherein the pattern is a reoccurrence of the specific user device transitioning between the idle and active states;
when a management entity that communicates with the communication tower detects the pattern of the specific user device transitioning between the idle and active states, identifying an idle state duration using the pattern of the specific user device transitioning between idle and active states, wherein the idle state duration is an amount of time that the specific user device persists in an idle state by not communicating data to a communication tower before transitioning to an active state by communicating data to the communication tower;
upon identifying the pattern of the specific user device transitioning between the idle and active states, trigger deep packet inspection of the data associated with the mobile device;
designating an inactivity time duration for the specific user device that is at least as long as the idle state duration identified and that is based on the deep packet inspection; and
setting an inactivity timer of the communication tower that communicates with the specific user device to match the inactivity time duration that is at least as long as the idle state duration identified,
wherein setting the inactivity timer of the communication tower to have a duration that is at least as long as the idle state duration identified prevents the communication tower from modifying a traffic path of the specific user device before the inactivity timer expires, as started by the communication tower receiving data from the specific user device.

8. The method of claim 7 , wherein the method further comprises identifying a respective inactivity time duration for each of a plurality of user devices that communicate with the communication tower.

9. The method of claim 7 , wherein the method further comprises when the communication tower determines that the specific user device did not subsequently transmit data before the inactivity timer expired, detecting a transition of the specific user device and modifying a traffic path of the specific user device by initiating a tear down of a traffic path used by the specific user device.

10. The method of claim 7 , wherein the inactivity time duration for the specific user device is designated in accordance with an inactivity timer update received from the management entity that generated the inactivity timer update based on the pattern of the specific user device transitioning between an idle state and an active state.

11. The method of claim 10 , wherein the method further comprising learning, by the management entity, the pattern of the specific user device transitioning between an idle and active state from data provided to the management entity, the data corresponding to at least the indication of the specific user device transition between an idle and active state.

12. The method of claim 7 , wherein the setting the inactivity timer of the communication tower to match the designated inactivity time duration reduces transitions of the mobile device between active states and idle states when the designated inactivity time duration is a greater amount of time than the pattern of idle state durations exhibited by the specific user device.

13. A system for facilitating reduction of transitions between active and idle states, the method comprising:
a management entity configured to:
communicate with a communication tower that communicates with a user device,
receive, via the communication tower, an indication of the user device transitioning between active states and idle states based on the user device communicating data packets to the communication tower,
recognizing, from the indication, a pattern exhibited by the user device in transitioning between active states and idle states, wherein the pattern is a duration of time during which the user device enters into the idle state and remains in the idle state until returning to the active state, and wherein in the idle state the user device does not transmit data to the communication tower, and
upon recognizing the pattern of the user device transitioning based on the indication, trigger deep packet inspection of the data packets associated with the user device by communicating a deep packet inspection request;

a connectivity gateway configured to:
receive the deep packet inspection request,
identify at least one of the data packets associated with the user device, and
initiate a deep packet inspection of the at least one data packet; and

a deep packet inspector configured to:
perform the deep packet inspection of the at least one data packet as initiated by the connectivity gateway,
obtain data related to the transitions of the user device between active states and idle states, and
communicate the data obtained from t
