Abstract

A mobile device may include a plurality of physical antennas configured to receive and transmit data. The physical antennas may be virtualized to enable efficient access and utilization of the computing resources of the physical antenna. Furthermore, the mobile device may support containerization of application executed by the mobile device. The virtualized physical antennas may be provided to various containers executed by the mobile device. Furthermore, a priority mechanism may be used to manage container access to the physical antennas.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
initializing a set of virtual antenna interfaces configured to enable containers to access physical antenna resources, where the containers are supported by a virtualization layer executed by a mobile device;
providing at least a portion of the set of virtual antenna interfaces to a first container;
receiving a request from the first container through a first virtual antenna interface of the portion of the set of virtual interfaces provided to the first container;
determining a priority associated with the request;
placing the request in a first priority ring of a plurality of priority rings based at least in part on the determined priority, where the plurality of priority rings have a prioritization of the plurality of priority such that requests in a higher priority ring are selected for processing prior to requests in a lower priority ring based at least in part on the prioritization; and
processing the request as a result of the priority ring being a highest priority ring with requests to be processed.

2. The computer-implemented method of claim 1 , further comprising assigning a first share of access to physical antenna resources to the first priority ring, where the first share indicates an amount of time the physical antenna resources may be utilized to fulfill requests queued in the first priority ring.

3. The computer-implemented method of claim 1 , wherein providing at least the portion of the set of virtual antenna interfaces to the first container further comprises exposing, by an agent executed by the mobile device, the portion of the set of virtual antenna interfaces such that the first container may provide requests to the portion of the set of virtual antenna interfaces.

4. The computer-implemented method of claim 3 , further comprising assigning, by the agent, the priority to the first container.

5. A system, comprising:
one or more processors; and
a memory that includes instructions that, if executed by the one or more processors, cause the system to:
initialize a virtual antenna interface associated with a physical antenna, where the virtual antenna interface is provided a virtualization layer that enables a container to utilize the physical antenna through the virtual antenna interface;
expose the virtual antenna interface to the container;
receive, at the virtual antenna interface, a request from the container, where the request includes priority information;
determine a priority associated with the request based at least in part on the priority information;
place the request in a highest priority ring of a plurality of priority rings having a prioritization of the plurality of priority rings where requests are selected to be processed based at least in part on the prioritization; and
process the request according to the prioritization and the request having the highest priority according to the prioritization.

6. The system of claim 5 , wherein the plurality of priority rings further comprises a lower priority ring and a lowest priority ring, where requests queued in the lower priority ring are processed after requests in the highest priority ring and requests queued in the lowest priority ring are processed after requests in the lower priority ring.

7. The system of claim 6 , wherein the memory further includes instructions that, if executed by the one or more processors, cause the system to assign, by an agent executing at an operating system level, operating system requests to the highest priority ring.

8. The system of claim 6 , wherein the memory further includes instructions that, if executed by the one or more processors, cause the system to assign, by an agent executing at an operating system level, user requests to the lower priority ring.

9. The system of claim 6 , wherein the memory further includes instructions that, if executed by the one or more processors, cause the system to assign, by an agent executing at an operating system level, requests associated with test operations to a lowest level priority ring.

10. The system of claim 5 , wherein initializing the virtual antenna interface further comprises initializing a single virtual antenna interface of a plurality of physical antennas of the system.

11. The system of claim 5 , wherein initializing the virtual antenna interface further comprises initializing, for each physical antenna of the system, wherein the system further includes a plurality of physical antennas and at least a portion of the plurality of physical antennas are of different types, a single virtual antenna interface.

12. The system of claim 5 , wherein initializing the virtual antenna interface further comprises loading into memory of the system a virtual device driver.

13. A non-transitory computer-readable storage medium having stored thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:
provide to a container a set of virtual antenna interfaces associated with a set of physical antennas, where each virtual antenna interface of the set of virtual antenna interfaces is provided by a virtualization layer that enables the container to access a particular physical antenna of the set of physical antennas through the virtual antenna interface;
receive, at a first virtual antenna interface corresponding to a first physical antenna, a request from the container;
determine a priority associated with the request based at least in part on information associated with the container; and
process the request from a priority ring of a plurality of priority rings having a prioritization of the plurality of priority rings where requests are selected to be processed based at least in part on the prioritization and the priority ring for the request is determined based at least in part on the priority associated with the request.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the instructions that cause the computer system to determine the priority associated with the request further include instructions that cause the computer system to determine the priority associated with the request based at least in part on an application responsible for generating the request.

15. The non-transitory computer-readable storage medium of claim 13 , wherein the instructions that cause the computer system to determine the priority associated with the request further include instructions that cause the computer system to determine the priority associated with the request based at least in part on one or more factors including the container associated with the request, one or more other requests dependent on the request, and a point in time at which the request was submitted.

16. The non-transitory computer-readable storage medium of claim 13 , wherein the instructions further comprise instructions that, as a result of being executed by the one or more processors, cause the computer system to assign the priority to the container during initialization of the container.

17. The non-transitory computer-readable storage medium of claim 13 , wherein the virtualization layer is a hypervisor.

18. The non-transitory computer-readable storage medium of claim 13 , wherein the instructions that cause the computer system to receive the request from the container further include instructions that cause the computer system to receive the request from an agent executed by the container and running within a container namespace and control group.
