Abstract

A method (400, 500) and a system 200 for managing service in an access network (110) for wireless communication. The method can include monitoring at least one environmental condition and, responsive to detecting a change in the environmental condition, adjusting at least one service parameter. The system can include an environmental detector (130) that monitors at least one environmental condition and a processor (202) that, responsive to detecting a change in the environmental condition, adjusts at least one service parameter.

Claims

1. A method of managing service in an access network for wireless communication, comprising:

monitoring a weather condition including at least one of a wind speed, a humidity, and a precipitation rate;

responsive to detecting a change in the weather condition, adjusting at least one wireless communication service parameter selected from a group consisting of a latency of a control message, a response time of the control message, number of access points that attempt a call setup, and a paging repeat parameter;

comparing an actual data throughput to a target data throughput; and

responsive to the actual data throughput being less than the target data throughput by at least a threshold value, adjusting the wireless communication service parameter.

2. The method of claim 1, wherein:

monitoring the weather condition comprises measuring a value associated with the weather condition; and

adjusting the wireless communication service parameter comprises adjusting the wireless communication service parameter to a service parameter value that corresponds to the measured value of the weather condition.

3. The method of claim 2, further comprising:

identifying a range corresponding to the measured value of the weather condition; and

selecting the service parameter value based on the identified range.

4. The method of claim 2, further comprising:

calculating the service parameter value based upon the measured value of the weather condition.

5. The method of claim 1, further comprising:

measuring a quality of service parameter associated with the wireless communication service parameter;

wherein adjusting the wireless communication service parameter comprises changing the wireless communication service parameter to a value that decreases a difference between the measured quality of service and a target quality of service.

6. The method of claim 1, further comprising:

monitoring a rate of failures associated with the wireless communication service parameter; and

responsive to the rate of failures exceeding a threshold value, adjusting the wireless communication service parameter.

7. The method of claim 1, wherein the control message is selected from the group consisting of a channel assignment message, a hand-off message, a soft hand-off message, and a page message.

8. A system for managing service in an access network for wireless communication, comprising:

an environmental detector that monitors a weather condition including at least one of a wind speed, a humidity, and a precipitation rate; and

a processor that, responsive to detecting a change in the weather condition, adjusts at least one wireless communication service parameter selected from a group consisting of a latency of a control message, a response time of the control message, number of access points that attempt a call setup, and a paging repeat parameter,

wherein the processor compares an actual data throughput to a target data throughput and, responsive to the actual data throughput being less than the target data throughput by at least a threshold value, adjusts the wireless communication service parameter.

9. The system of claim 8, wherein the environmental detector comprises at least one of a wind speed detector, a rain detector, and a humidity detector.

10. The system of claim 8, wherein:

the environmental detector measures a value associated with the weather condition; and

the processor adjusts the wireless communication service parameter to a service parameter value that corresponds to the measured value of the weather condition.

11. The system of claim 10, wherein:

the processor identifies a category corresponding to the measured value of the weather condition and selects the service parameter value based on the identified category.

12. The system of claim 10, wherein the processor calculates the service parameter value based upon the measured value of the weather condition.

13. The system of claim 10, wherein the processor measures a quality of service associated with the wireless communication service parameter and changes the wireless communication service parameter to a value that decreases a difference between the measured quality of service and a target quality of service.

14. The system of claim 8, wherein the processor monitors a rate of failures associated with the wireless communication service parameter and, responsive to the rate of failures exceeding a threshold value, adjusts the wireless communication service parameter.

15. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method of managing service in an access network for wireless communication, the method comprising:

monitoring a weather condition including at least one of a wind speed, a humidity, and a precipitation rate;

responsive to detecting a change in the weather condition, adjusting at least one wireless communication service parameter selected from a group consisting of a latency of a control message, a response time of the control message, number of access points that attempt a call setup, and a paging repeat parameter;

comparing an actual data throughput to a target data throughput; and

responsive to the actual data throughput being less than the target data throughput by at least a threshold value, adjusting the wireless communication service parameter.
