Abstract

Concepts and technologies are disclosed herein for identifying a network resource in a wireless networking environment as essential. A network resource to be tested is identified. The network resource is transitioned to a softbar operation state. In the softbar operation state, use of the network resource is avoided. If access data indicates substantial use of the network resource, the network resource can be identified as essential.

Claims

1. A computer-implemented method for identifying a network resource (102) in a wireless networking environment (100) as essential, the method comprising computer-implemented operations for:

identifying a network resource (102) to be tested;

transitioning the network resource (102) to a softbar operation state in which use of the network resource (102) is avoided;

determining if access data (112) indicates a substantial use of the network resource (102); and

identifying the network resource (102) as essential based upon determining that the access data (112) indicates substantial use of the network resource (102).

2. The method of claim 1, wherein the softbar state further comprises an operation state in which use of the network resource (102) is allowed for an attempt to use the network resource (102) as a last resort.

3. The method of claim 1, further comprising:

determining a time period during which the network resource (102) is to be operated in the softbar state;

determining if the time period has expired; and

obtaining the access data (112) in response to determining that the time period has expired.

4. The method of claim 1, further comprising identifying the network resource (102) as non-essential by determining that access data (112) does not indicate a substantial use of the network resource (102).

5. The method of claim 1, wherein the access data (112) comprises data identifying usage of the network resource (102) during the time period.

6. The method of claim 1, further comprising taking an action to reduce the power consumption of the network resource (102), in response to identifying the network resource (102) as non-essential.

7. A computer-implemented method for identifying a network resource (102) in a wireless networking environment (100) as essential, the method comprising computer-implemented operations for:

identifying, at a central controller (108), a network resource (102) to be tested;

defining a time period during which the network resource (102) is to be tested;

generating a command (110) for transitioning the network resource (102) to a softbar operation state in which use of the network resource (102) is avoided;

determining if the time period has expired; and

in response to determining that the time period has expired,

obtaining access data (112) describing activity associated with the network resource (102) during the time period, and

identifying the network resource (102) as an essential network resource (102) in response to determining that the access data (112) indicates substantial usage of the network resource (102) during the time period.

8. The method of claim 7, further comprising generating a command (110) for transitioning the network resource (102) out of a softbar operation state, in response to determining that the time period has expired.

9. The method of claim 7, further comprising identifying the network resource (102) as a non-essential network resource (102) in response to determining that the access data (112) does not indicate substantial usage of the network resource (102) during the time period.

10. The method of claim 7, further comprising:

in response to determining that the time period has not expired, maintaining the network resource (102) in the softbar operation state.

11. The method of claim 7, wherein the network resource (102) comprises a base station (202) of the wireless networking environment (100), and determining if the access data (112) does not indicate substantial usage of the network resource (102) during the time period comprises determining that the time period has expired without an attempted handover of a communication to the base station (202).

12. The method of claim 11, further comprising receiving the access data (112) from the base station (202), the access data (112) comprising data indicating activity associated with the base station (202) during the time period.

13. The method of claim 7, further comprising receiving access data (112) comprising data indicating activity associated with the network resource (102) during the time period.

14. A central controller (108) configured to identify a network resource (102) as essential, the central controller (108) comprising a central processing unit (602) in communication with a mass storage device (612), wherein execution of computer-executable instructions stored in the mass storage device (612) cause the central processing unit (602) to:

identify a network resource (102) to be tested;

define a time period during which the network resource (102) is to be tested;

generate a command (112) for transitioning the network resource (102) to a softbar operation state in which use of the network resource (102) is avoided;

determine if the time period has expired; and

in response to determining that the time period has expired,

obtaining access data (112) describing activity associated with the network resource (102) during the time period, and

identify the network resource (102) as a non-essential network resource (102) in response to determining that the access data (112) indicates substantial usage of the network resource (102) during the time period.

15. The central controller (108) of claim 14, wherein execution of the computer-executable instructions stored in the mass storage device (612) further cause the central processing unit (602) to generate a command (110) for transitioning the network resource (102) out of a softbar operation state, in response to determining that the time period has expired.

16. The central controller (108) of claim 15, wherein execution of the computer-executable instructions stored in the mass storage device (612) cause the central processing unit (602) to identify the network resource (102) from a plurality of network resources (102), and the plurality of network resources (102) provide services to a geographic area.

17. The central controller (108) of claim 16, wherein the plurality of network resources (102) comprises a plurality of base stations (202), each of the plurality of base stations (202) having a respective coverage area (204), and at least two of the coverage areas (204) of the base stations (202) overlap, at least partially.
