Communication state transitioning control
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for managing state transitions of communication circuitries in wireless networks. Embodiments manage radio resource control (RRC) state transitions and/or discontinuous reception (DRX) state transitions. Other embodiments may be described and/or claimed.
1. An apparatus comprising:
timer circuitry configured to set a first tracking window; and
communication-state circuitry coupled with the timer circuitry and configured to:
determine a first number of state transitions by communication circuitry that occur within the first tracking window;
compare the first number of state transitions to a first predetermined threshold;
suppress state transitions based on comparison of the first number of state transitions to the first predetermined threshold; and
decrease an inactivity period based on a determination that a second number of state transitions that occur within a second tracking window is less than a second predetermined threshold,
wherein the state transitions comprise transitions between a radio resource control (RRC) connected state and an RRC idle state or transitions between discontinuous reception (DRX) configurations.
2. The apparatus of claim 1 , wherein the transitions between DRX configurations comprise updating one or more parameters of DRX operation.
3. The apparatus of claim 1 , wherein the state circuitry is configured to suppress state transitions by being configured to:
transmit a transition-suppress message to request an enhanced node base station (eNB) to refrain from issuing transition instructions.
4. The apparatus of claim 1 , further comprising:
an inactivity timer,
wherein the communication-state circuitry is further configured to set the inactivity timer to a state-transition disable period value based on comparison of the first number of state transitions to the first predetermined threshold, and
transmit, based on an expiration of the inactivity timer, a transition request message to request instructions to perform a state transition.
5. The apparatus of claim 1 , wherein the communication-state circuitry is further configured to receive one or more configuration messages from an enhanced node base station (eNB), the one or more configuration messages to indicate values that correspond to the first tracking window and the first predetermined threshold.
6. The apparatus of claim 5 , wherein the one or more configuration messages are received as part of radio resource control (RRC) configuration of the apparatus.
7. The apparatus of claim 1 , further comprising:
a counter,
wherein the communication-state circuitry is further configured to increment the counter for each state transition that occurs in the first tracking window.
8. The apparatus of claim 1 , wherein the communication-state circuitry is configured to suppress state transitions by being configured to:
increase the inactivity period based on a determination that the first number of state transitions is greater than the first predetermined threshold.
9. The apparatus of claim 8 , wherein the communication-state circuitry is configured to increase the inactivity period by a delta value or by one or more increments within a table of inactivity period values.
10. The apparatus of claim 9 , wherein the communication-state circuitry is configured to receive the delta value or the table of inactivity period values in a radio resource control message from an enhanced node base station.
11. The apparatus of claim 8 , wherein the communication-state circuitry is further configured to:
set a timer of the timer circuitry based on increase in the inactivity period; and
decrease the inactivity period based on expiration of the timer.
12. The apparatus of claim 1 , wherein the apparatus comprises a user equipment that further includes a touchscreen user interface.
13. The apparatus of claim 1 , wherein the communication-state circuitry is further configured to:
determine whether to suppress state transitions by disabling an inactivity timer for a state-transition disable period or by increasing the inactivity period.
14. An article of manufacture comprising one or more non-transitory storage media having instructions that, when executed, cause a user equipment (UE) to:
receive configuration parameters in one or more configuration messages from an enhanced node base station (eNB), the configuration parameters indicating a tracking timer value and a counter threshold value;
compare a first number of state transitions performed by communication circuitry within a first tracking window, which corresponds to tracking timer value, with the counter threshold value;
suppress a state transition based on the comparison; and
decrease an inactivity period based on a determination that a second number of state transitions that occur within a second tracking window is less than a second predetermined threshold,
wherein the state transitions are radio resource control (RRC) state transitions that include transitions from RRC_connect to RRC_idle or transitions from RRC_idle to RRC_connect or transitions between DRX configurations.
15. The article of manufacture of claim 14 , wherein the transitions between DRX configurations include updating one or more parameters of DRX operation.
16. The article of manufacture of claim 14 , wherein the state transitions are autonomous state transitions that are performed by the UE without instruction by the eNB.
17. The article of manufacture of claim 14 , wherein the instructions, when executed, cause the UE to:
suppress the state transition by increasing the inactivity period by a delta value or by one or more increments within a table of inactivity period values.
18. The article of manufacture of claim 17 , wherein the instructions, when executed, further cause the UE to:
set a timer of the timer circuitry based on increase in the inactivity period; and
decrease the inactivity period based on expiration of the timer.
