Abstract

Traffic associated with user equipment that are coupled to a first radio access network is steered to a second radio access network based on an adaptable signal strength criterion. The signal strength criterion is related to real-time network load conditions of the first radio access network and can be broadcasted from a serving access point to the user equipment. Moreover, the signal strength criterion facilitates steering, to the second radio network, traffic associated with user equipment that are located closer to a cell edge of the first radio access network before steering traffic associated with user equipment are located further away from the cell edge. In addition, based on the network congestion within the first radio access network, the signal strength criterion is modified to adjust the number of user equipment that are steered to the second radio network.

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;

mapping network load data associated with an access point device to a first signal strength to determine a signal strength threshold, wherein the signal strength threshold corresponds to a classification value generated as a function of a mapping of an input attribute vector associated with the access point device;

in response to an analysis of the network load data, updating device steering data to adjust a user equipment of a number of user equipment that are to be steered from the access point device to a network device of a second radio access network; and

in response to determining a second signal strength associated with the user equipment satisfies the signal strength threshold, facilitating a transmission of the device steering data to the user equipment via the access point device.

2. The system of claim 1, wherein the signal strength threshold represents a threshold of a strength of a signal transmitted from the access point device to one of the user equipment.

3. The system of claim 2, wherein the updating comprises decreasing the threshold in response to determining that congestion of network devices of a first radio access network, associated with the access point device, has decreased.

4. The system of claim 2, wherein the updating comprises increasing the threshold in response to determining that congestion of network devices of a first radio access network, associated with the access point device, has increased.

5. The system of claim 1, wherein the updating the device steering data is based on an indication that the user equipment is farther from the access point device than the number of user equipment.

6. The system of claim 1, wherein the signal strength threshold is based on a previously used signal strength threshold.

7. The system of claim 6, wherein the previously used signal strength threshold is assigned to macro network devices of a macro network.

8. The system of claim 6, wherein the previously used signal strength threshold is assigned to network devices of a wireless fidelity network.

9. The system of claim 6, wherein the previously used signal strength threshold is assigned to femto network devices of a femto network.

10. The system of claim 1, wherein the mapping comprises mapping the device steering data based on distribution data indicative of a distribution of the user equipment within a coverage area of the access point device as a function of time.

11. A method, comprising:

receiving, by a user equipment comprising a processor, network load data and signal strength data associated with an access point device;

determining, by the user equipment, a corresponding signal strength in relation to the network load data, wherein the corresponding signal strength comprises a signal strength threshold selected to facilitate a network selection based on user equipment steering criteria, and wherein the signal strength threshold corresponds to a classification value generated as a function of a mapping of an input attribute vector associated with the access point device; and

in response to the corresponding signal strength being determined to satisfy the signal strength threshold, facilitating, by the user equipment, the network selection to determine a radio access network that is to be employed by the user equipment for communication.

12. The method of claim 11, wherein the network load data corresponds to a category associated with a throughput of the access point device.

13. The method of claim 11, wherein a signal strength threshold is associated with a signal strength range.

14. The method of claim 11, further comprising:

wherein signal strength threshold data represents a threshold of a strength of a signal received by the user equipment from the access point device, and wherein the facilitating comprises comparing the signal strength threshold data with received signal strength data that represents the strength of the signal received by the user equipment from the access point device.

15. The method of claim 14, wherein the receiving comprises receiving the signal strength data via a system information block message.

16. The method of claim 15, wherein the network load data is appended to the system information block message.

17. A non-transitory computer-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

based on load data representing a network load associated with a first access point device, selecting communication data, associated with a user equipment, to be steered from the first access point device to a second access point device;

selecting a signal strength threshold to facilitate a steering of the communication data from the first access point device to the second access point device, wherein the signal strength threshold corresponds to a classification value generated as a function of mapping an input attribute vector associated with the second access point device; and
