Abstract

A radio access network system is described that determines a signal metric associated with a user equipment or device. The user equipment device can implement an altered transmission policy. The altered transmission policy can alter a strength of transmissions by increasing power consumption per transmission, increasing a length of timer per transmission, and altering other parameters of transmissions. The altered transmission policy can also alter an error correction policy. The error correction policy can indicate that error correction transmissions are to be decreased. The altered transmission policy can be implemented until the signal metric changes to a more desirable level.

First claim

What is claimed is:

1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
in response to determining that a first user equipment, which belongs to a defined category of devices, is predicted to be located within a geographical area, determining correlation data representing a correlation between the defined category and the geographical area, wherein the correlation data is determined based on historical data indicative of a signal metric, associated with signals transmitted between at least one second user equipment and an access point device that serves the geographical area, satisfying a defined criterion with respect to a threshold quantity of occurrences, and wherein the at least one second user equipment is determined to belong to the defined category; and
based on the correlation data, altering policy data representing a transmission policy that facilitates a transmission of a data packet between the access point device and the first user equipment.

2. The system of claim 1 , wherein the altering the policy data results in altered policy data and the operations further comprise:
based on the altered policy data, facilitating the transmission of the data packet.

3. The system of claim 1 , wherein the defined category is defined by a particular device make of the first user equipment.

4. The system of claim 1 , wherein the defined category is defined by a particular device model of the first user equipment.

5. The system of claim 1 , wherein the defined category is defined by a particular battery power level.

6. The system of claim 1 , wherein the policy data is associated with an error correction policy.

7. The system of claim 1 , wherein the altering comprises modifying a transmission power employable to transmit the data packet.

8. The system of claim 1 , wherein the altering comprises modifying a number of error correction bits that are to be transmitted per data packet.

9. The system of claim 1 , wherein the altering comprises a length of time for a data transmission associated with the first user equipment.

10. A method, comprising:
in response to determining that a first user equipment, which belongs to a defined category of devices, is located within a geographical area, determining, by a system comprising a processor, correlation data representing a correlation between the defined category and the geographical area, wherein the determining the correlation data comprises determining the correlation data based on historical data indicative of a signal metric, associated with signals transmitted between at least one second user equipment and an access point device that serves the geographical area, satisfying a defined function with respect to a threshold frequency of occurrences, and wherein the at least one second user equipment is determined to belong to the defined category; and
based on the correlation data, updating, by the system, policy data representing a transmission policy that is utilized to transmit a data packet between the access point device and the first user equipment.

11. The method of claim 10 , wherein the determining that the first user equipment is located within the geographical area comprises determining that the first user equipment is located within the geographical area based on accelerometer data received from an accelerometer of the first user equipment.

12. The method of claim 10 , wherein the determining that the first user equipment is located within the geographical area comprises determining that the first user equipment is located within the geographical area based on global position satellite data associated with the first user equipment.

13. The method of claim 10 , wherein the defined category is defined by a particular device make of the first user equipment.

14. The method of claim 10 , wherein the defined category is defined by a particular device model of the first user equipment.

15. The method of claim 10 , wherein the defined category is defined by a particular battery power level.

16. The method of claim 10 , wherein updating the policy data comprises updating policy data representing an error correction policy associated with a transmission of the data packet.

17. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a system, facilitate performance of operations, comprising:
in response to verifying that a first user equipment, belonging to a defined category of devices, is located within a geographical area, determining correlation data representing a correlation between the defined category and the geographical area, wherein the correlation data is determined based on historical data indicative of a signal metric associated with signals transmitted between at least one second user equipment and an access point device that serves the geographical area, satisfying a defined criterion that is a function of a threshold quantity of times, and wherein the at least one second user equipment is determined to belong to the defined category; and
based on the correlation data, updating policy data representing a transmission policy that is utilized to transmit a data packet between the access point device and the first user equipment.

18. The non-transitory machine-readable medium of claim 17 , wherein updating the policy data comprises updating an error correction policy associated with a transmission of the data packet.

19. The non-transitory machine-readable medium of claim 17 , wherein the defined category is defined by a particular device model.

20. The non-transitory machine-readable medium of claim 17 , wherein the defined category is defined by a particular a device manufacturer.
