Abstract

Signal markers are placed in critical locations within the wireless network. Critical locations are locations where signals from base stations may be weak due to natural or man-made obstruction and locations where user demand for network resources may be particularly heavy. The signal markers collect data such as the signal strength or amplitude of signals from surrounding base stations, and the amount of user demand for access to the network. The signal markers then communicate this data to the mobile switching center. The mobile switching center analyzes the data and, if the data indicates unsatisfactory performance, determines new parameters for the base stations. The mobile switching center then communications the new parameters to each of the base stations where each of the base stations changes its performance in accordance with the new parameters. The signal markers then once again collect data and communicate that data to the mobile switching center where further changes to base station parameters are made as necessary.

Claims

1. A wireless communication network, comprising:

a base station that transmits at least one base station signal;

a mobile switching center that communicates at least one antenna parameter to the base station; and

a first signal marker that determines a first value for each of at least one of a plurality of signal characteristics of the at least one base station signal to form a first value set and communicates the first value set to the mobile switching center, where the mobile switching center determines the at least one antenna parameter using the first value set.

2. The wireless communication network of claim 1, further comprising:

a second signal marker that determines a second value for each of at least one of the plurality of signal characteristics of the at least one base station signal to form a second value set and communicates the second value set to the mobile switching center, where the mobile switching center determines the at least one antenna parameter using the second value set.

3. The wireless communication network of claim 1, wherein at least two of the first values in the first value set correspond to the same signal characteristic of two different base station signals transmitted by the base station.

4. The wireless communication network of claim 1, wherein at least two of the first values in the first value set correspond to two different signal characteristics of the same base station signal.

5. The wireless communication network of claim 1, wherein the at least one parameter specifies an antenna height.

6. The wireless communication network of claim 1, wherein the at least one parameter specifies an antenna elevation angle.

7. The wireless communication network of claim 1, wherein the at least one parameter specifies an antenna azimuth.

8. The wireless communication network of claim 1, wherein the at least one parameter specifies an antenna beam shape.

9. The wireless communication network of claim 1, wherein the at least one parameter specifies an antenna beam position.
