Abstract

A method, an apparatus, and a computer program product for scaling one or more processing resources in a wireless communication system. One or more processing resources being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments are monitored. Based on the monitoring, a determination of whether to change an assignment of one or more processing resources in the plurality of containers is made. Based on the determination, the assignment of one or more processing resources is changed.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
monitoring one or more processing resources being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments;
determining, based on the monitoring, whether to change an assignment of the one or more processing resources in the plurality of containers;
changing, based on the determining, the assignment of the one or more processing resources;
upgrading the one or more processing resources using one or more resource definitions associated with one or more upgrades;
deploying the one or more upgraded processing resources;
monitoring the one or more deployed upgraded processing resources using one or more key performance indicators; and
rolling back one or more deployed upgrades to the one or more processing resources upon determining that the one or more deployed upgraded processing resources do not meet the one or more key performance indicators.

2. The method according to claim 1 , wherein the plurality of containers are configured to operate in a cloud computing environment to provide one or more services of at least one control plane component and at least user plane component of a centralized unit of a base station.

3. The method according to claim 1 , wherein at least one of the monitoring, the determining, and the changing is performed by at least one base station in a wireless communication system.

4. The method according to claim 3 , where the base station includes at least one of the following: a base station, an eNodeB base station, a gNodeB base station, a wireless base station, a wireless access point, and any combination thereof.

5. The method according to claim 4 , wherein the base station is a base station operating in at least one of the following communications systems: a long term evolution communications system, a new radio communications system, a wireless communication system, and any combination thereof.

6. The method according to claim 5 , wherein the base station includes at least one centralized unit, the centralized unit include at least one of: a control plane component, a user plane component, and any combination thereof.

7. The method according to claim 1 , wherein one or more user equipments in the plurality of user equipments in the plurality of user equipments is associated with a radio resource control (RRC) status, the RRC status including at least one of the following: an RRC-inactive status, RRC-IDLE status, an RRCE connected status, and any combination thereof.

8. The method according to claim 1 , wherein the monitoring includes monitoring one or more metrics associated with the one or more processing resources.

9. The method according to claim 8 , wherein the one or more metrics include at least one of the following: a number of user equipments being processed by the at least one container, a throughput associated with processing of at least one user equipment by the at least one container, one or more data radio bearers associated with the at least one user equipment, and any combination thereof.

10. The method according to claim 1 , wherein the at least one container is associated with at least one of: at least one control plane component and at least user plane component of a centralized unit of a base station.

11. The method according to claim 1 , wherein the upgrading includes executing the one or more upgrades using one or more upgrade sequences.

12. The method according to claim 1 , wherein the changing including changing the assignment of the one or more processing resources using one or more resource definitions associated with one or more control plane and user plane components of a centralized unit of a base station.

13. The method according to claim 1 , wherein the changing includes executing one or more changing of the assignment of the one or more processing resources operations using one or more changing sequences.

14. An apparatus, comprising:
at least one processor, and
at least one non-transitory storage media storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
monitoring one or more processing resources being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments;
determining, based on the monitoring, whether to change an assignment of the one or more processing resources in the plurality of containers;

changing, based on the determining, the assignment of the one or more processing resources;
upgrading the one or more processing resources using one or more resource definitions associated with one or more upgrades;
deploying the one or more upgraded processing resources;
monitoring the one or more deployed upgraded processing resources using one or more key performance indicators; and
rolling back one or more deployed upgrades to the one or more processing resources
upon determining that the one or more deployed upgraded processing resources do not meet the one or more key performance indicators.

15. At least one non-transitory story media storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
monitoring one or more processing resources being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments;
determining, based on the monitoring, whether to change an assignment of the one or more processing resources in the plurality of containers;

changing, based on the determining, the assignment of the one or more processing resources;
upgrading the one or more processing resources using one or more resource definitions associated with one or more upgrades;
deploying the one or more upgraded processing resources;
monitoring the one or more deployed upgraded processing resources using one or more key performance indicators; and
rolling back one or more deployed upgrades to the one or more processing resources
upon determining that the one or more deployed upgraded processing resources do not meet the one or more key performance indicators.
