Method and arrangement for grace period control associated with a service level in a cellular communications system
A method in a telecom node for controlling a grace period associated with a licensed capacity usage in the telecom node is provided. The telecom node is comprised in a cellular telephone network. The licensed capacity usage is associated with a capacity license limit. The telecom node measures ( 201 ) over a specific amount of time, the capacity usage in the telecom node overshooting the capacity license limit. When the measured capacity usage exceeds a preset value of an allowed capacity usage overshoot, the telecom node triggers ( 202 ) a grace period of the licensed capacity usage at the expiry of the specific amount of time. During the grace period capacity usage overshoot is allowed. Upon expiry of said grace period the licensed capacity usage is enforced according to the capacity license limit unless the licensed capacity usage is increased.
1. A method, implemented in a telecom node of a cellular telephone network, for controlling a grace period associated with a licensed capacity usage in the telecom node, wherein the licensed capacity usage is associated with a capacity license limit, the method comprising:
measuring, over a specific amount of time, the capacity usage in the telecom node overshooting the capacity license limit based on at least one of determining a load of the telecom node, counting a number of user equipments communicating with the telecom node, and determining an amount of a resource used in the communication with the user equipments;
in response to the measured capacity usage overshooting the capacity license limit by exceeding a preset value of an allowed capacity usage overshoot, triggering a grace period of the licensed capacity usage at the expiry of the specific amount of time, during which grace period capacity usage overshoot is allowed; and
upon expiry of the grace period, enforcing the licensed capacity usage of the telecom node according to the capacity license limit unless the licensed capacity usage is increased.
2. The method of claim 1 , further comprising resetting the grace period in response to the licensed capacity usage being increased by at least a minimum increase threshold to enable the grace period to be triggered again.
3. The method of claim 2 , further comprising saving the increased licensed capacity usage as an original licensed capacity usage each time the grace period is reset.
4. The method of claim 1 , wherein:
the telecom node comprises a base station;
the determining of the load of the telecom node comprises determining a load of the base station by monitoring a buffer status in the base station; and
the measuring of the capacity usage overshooting the capacity license limit comprises measuring the capacity usage overshooting the capacity license limit based on the determined load of the base station.
5. The method of claim 1 , wherein:
the telecom node comprises a Long Term Evolution eNodeB;
the determining of the amount of the resource used in the communication with the user equipments comprises determining at least one of a number of resource blocks and a number of resource elements transmitted in a subframe, frame, or group of frames; and
the measuring of the capacity usage overshooting the capacity license limit comprises measuring the capacity usage overshooting the capacity license limit based on at least one of the determined number of resource blocks and the determined number of resource elements transmitted in the subframe, frame, or group of frames.
6. The method of claim 1 , wherein:
the telecom node comprises a base station;
the counting of the number of user equipments communicating with the telecom node comprises counting the number of user equipments connected to the base station; and
the measuring of the capacity usage overshooting the capacity license limit comprises measuring the capacity usage overshooting the capacity license limit based on the counted number of user equipments connected to the base station.
7. A telecom node in a cellular telephone network, the telecom node for controlling a grace period associated with a licensed capacity usage in the telecom node, wherein the licensed capacity usage is associated with a capacity license limit, the telecom node comprising a control processor configured to:
measure, over a specific amount of time, the capacity usage in the telecom node overshooting the capacity license limit, wherein the control processor is configured to measure the capacity usage overshooting the capacity license limit based on at least one of a determined load of the telecom node, a counted number of user equipments communicating with the telecom node, and a determined amount of a resource used in the communication with the user equipments;
in response to the measured capacity usage overshooting the capacity license limit by exceeding a preset value of an allowed capacity usage overshoot, trigger a grace period of the licensed capacity usage at the expiry of the specific amount of time, during which grace period capacity usage overshoot is allowed; and
upon expiry of the grace period, enforce the licensed capacity usage according to the capacity license limit unless the licensed capacity usage is increased.
8. The telecom node of claim 7 , wherein the control processor is further configured to reset the grace period in response to the licensed capacity usage being increased by at least a minimum increase threshold to enable the grace period to be triggered again.
9. The telecom node of claim 8 , wherein the control processor is further configured to save the increased licensed capacity usage as an original licensed capacity usage each time the grace period is reset.
10. The telecom node of claim 7 , wherein:
the telecom node comprises a base station;
the determined load of the telecom node comprises a load of the base station determined by monitoring a buffer status in the base station; and
the control processor is further configured to measure the capacity usage overshooting the capacity license limit based on the determined load of the base station.
11. The telecom node of claim 7 , wherein:
the telecom node comprises a Long Term Evolution eNodeB;
the determined amount of the resource used in the communication with the user equipments comprises at least one of a number of resource blocks and a number of resource elements transmitted in a subframe, frame, or group of frames; and
the control processor is further configured to measure the capacity usage overshooting the capacity license limit based on at least one of the determined number of the resource blocks and the determined number of the resource elements transmitted in the subframe, frame, or group of frames.
12. The telecom node of claim 7 , wherein:
the telecom node comprises a base station;
the counted number of user equipments communicating with the telecom node comprises a counted number of user equipments connected to the base station; and
the control processor is further configured to measure the capacity usage overshooting the capacity license limit based on the counted number of user equipments connected to the base station.
