Abstract

The disclosed subject matter relates to received signal strength indicator (RSSI) snapshot analysis. RSSI snapshot analysis can be independent of determining location/map information. An RSSI snapshot can be analyzed in view of historic RSSI information to determine a probability that a local wireless resource correlated with the historical RSSI information is within the service area of the user equipment. Machine learning can be employed to train an inference component to facilitate in determining the probability. In an aspect, the state of a wireless radio can be controlled based on the probability, which can reduce the energy consumption of the user equipment by facilitating selective enablement of a wireless radio.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving, before determining a location of a user equipment, signal strength indicator information;

comparing, before the determining the location of the user equipment, the signal strength indicator information to a historical signal strength indicator information comprising information relating to a corresponding wireless resource to determine a feature present in the historical signal strength indicator information and in the signal strength indicator information;

determining probability data representative of a probability that the corresponding wireless resource is available to participate in a link between the user equipment and the corresponding wireless resource and that the corresponding wireless resource is within a service area associated with the user equipment, wherein the probability is based on the comparing the signal strength indicator information and the historical signal strength indicator information;

altering, based on the probability data, an operational state of a wireless radio device of the user equipment; and

permitting, before the determining the location of the user equipment, the establishment of the link between the user equipment and the corresponding wireless resource.

2. The system of claim 1, wherein the comparing comprises determining a level of similarity between the signal strength indicator information and the historical signal strength indicator information.

3. The system of claim 1, wherein the comparing comprises determining a level of similarity between the signal strength indicator information and another historical signal strength indicator information of the library of historical signal strength indicator information.

4. The system of claim 3, wherein the comparing comprises ranking the historical signal strength indicator information and the other historical signal strength indicator information based on the level of similarity.

5. The system of claim 4, wherein the determining the probability data is based on the ranking.

6. The system of claim 1, wherein the probability is a probability that the corresponding wireless resource device is within the service area associated with the user equipment based on the comparing the signal strength indicator information and the historical signal strength indicator information and a relative strength of the signal strength indicator information.

7. The system of claim 1, wherein the determining further comprises determining that a condition relating to analysis of the signal strength indicator information and the historical signal strength indicator information is satisfied.

8. The system of claim 7, wherein the determining further comprises receiving a rule associated with the analysis.

9. The system of claim 1, wherein the operations further comprise, initiating the establishment of the link between the user equipment and the corresponding wireless resource.

10. The system of claim 9, wherein the initiating the establishment of the link is further based on a ranking of a historical strength indicator feature represented in the historical signal strength indicator information.

11. A method, comprising:

receiving, by a system comprising a processor, signal strength indicator information before determining a location of a user equipment;

receiving, by the system, historical signal strength indicator information corresponding to a wireless resource device before the determining the location of the user equipment;

based on correlated features common to the signal strength indicator information and the historical signal strength indicator information, determining, by the system, probability data indicative of a probability that the user equipment is within a service area of the wireless resource device and that the wireless resource device is available for establishment of a connection between the user equipment and the wireless resource device;

altering, by the system based on the probability data, a power state of a wireless radio device comprised in the user equipment; and

allowing, by the system prior to the determining the location of the user equipment, the user equipment to participate in the connection.

12. The method of claim 11, wherein the determining the probability data comprises determining the probability data based on a level of similarity determined between the signal strength indicator information and the historical signal strength indicator information.

13. The method of claim 11, further comprising ranking, by the system, the wireless resource device against another wireless resource device based on the probability data and other probability data associated with the other wireless resource device, wherein the ranking results in a determination of a higher ranked one of the wireless resource device and the other wireless resource device.

14. The method of claim 13, further comprising initiating, by the system, the connection between the user equipment and the higher ranked one of the wireless resource device and the other wireless resource device.

15. The method of claim 11, wherein the determining the probability comprises forming an inference relating to the historical signal strength indicator information.

16. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

before determining a location of a user equipment,

receiving signal strength indicator information, and

receiving historical signal strength indicator information corresponding to a wireless resource device;

based on a level of similarity between features of both the signal strength indicator information and the historical signal strength indicator information, determining, prior to determining a location of the wireless resource device, a probability that the wireless resource device is within a service area associated with the user equipment and that the wireless resource device is available for a connection between the user equipment and the wireless resource device;

transitioning a power state of the user equipment based on the probability; and
