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:
determining that a first user equipment is likely to be located within a defined geographical area served by access point devices of a communication network,
determining historical data associated with a signal metric associated with a signal transmitted between a second user equipment and an access point device of the access point devices, wherein a first device characteristic of the first user equipment and a second device characteristic of the second user equipment are determined to satisfy a match criterion, and
based on the historical data, modifying policy data representing a transmission policy that is employable to facilitate a transmission of an error correction data packet between the access point device and the first user equipment.

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

3. The system of claim 1 , wherein the transmission policy defines a number of error correction bits that are to be transmitted per packet.

4. The system of claim 1 , wherein the determining that the first user equipment is likely to be located within the defined geographical area comprises determining route data indicative of a route associated with the defined geographical area.

5. The system of claim 4 , wherein the determining the route data comprises determining the route data based on input data received via an interface of the first user equipment.

6. The system of claim 4 , wherein the determining the route data comprises determining the route data based on travel history data associated with locations that have been previously visited by the first user equipment.

7. The system of claim 1 , wherein the transmission policy is a first transmission policy and the modifying comprises modifying policy data representing a second transmission policy that defines a length of time for a data transmission associated with the first user equipment.

8. The system of claim 1 , wherein the wherein the transmission policy is a first transmission policy and the modifying comprises modifying policy data representing a second transmission policy that defines a transmission power criterion for a data transmission associated with the first user equipment.

9. The system of claim 1 , wherein the first user equipment and the second user equipment are determined to have a common device model.

10. The system of claim 1 , wherein the first user equipment and the second user equipment are determined to have a common device manufacturer.

11. The system of claim 1 , wherein the first user equipment and the second user equipment are determined to be assigned a common device classification.

12. A method, comprising:
determining, by a system comprising a processor, that a first user equipment is located within a defined geographical area served by access point devices of a communication network;
determining, by the system, a classification associated with the first user equipment;
determining, by the system, historical data associated with a second user equipment that is determined to be associated with the classification, wherein the historical data represents a signal metric associated with a signal transmitted between the second user equipment and an access point device of the access point devices; and
based on the historical data, updating, by the system, policy data representing a transmission policy that is employable to facilitate a transmission of an error correction data packet between the access point device and the first user equipment.

13. The method of claim 12 , wherein the determining the classification comprises determining a make of the first user equipment.

14. The method of claim 12 , wherein the determining the classification comprises determining a model of the first user equipment.

15. The method of claim 12 , wherein the determining the classification comprises determining an operating system employed by the first user equipment.

16. The method of claim 12 , wherein the determining that the first user equipment is located within the defined geographical area comprises determining that the first user equipment is located within the defined geographical area based on accelerometer data received from an accelerometer of the first user equipment.

17. A machine-readable storage medium, comprising executable instructions that, when executed by a processor of a system, facilitate performance of operations, comprising:
determining that a first mobile device is entering a defined geographical area served by access point devices of a communication network;
determining a first device characteristic of the first mobile device;
determining, by the system, historical data associated with a second mobile device having a second device characteristic that has been determined to match the first device characteristic, wherein the historical data represents a signal metric associated with a signal transmitted between the second mobile device and an access point device of the access point devices; and
based on the historical data, updating policy data indicative of a transmission policy that is employable to facilitate a transmission of an error correction data packet between the access point device and the first mobile device.

18. The machine-readable storage medium of claim 17 , wherein the determining that the first mobile device is entering the defined geographical area comprises determining that the first mobile device is entering the defined geographical area based on network data indicative of devices of communication networks, comprising the communication network, to which the first mobile device is coupled.

19. The machine-readable storage medium of claim 17 , wherein the determining that the first mobile device is entering the defined geographical area comprises determining that the first mobile device is entering the defined geographical area based on data from an inertial navigation system.

20. The machine-readable storage medium of claim 17 , wherein the determining that the first mobile device is entering the defined geographical area comprises determining that the first mobile device is entering the defined geographical area based on location history of the first mobile device.
