Abstract

A code division multiple access (CDMA) communication system (100) has improved control by accurately characterizing coverage and loading parameters related to the CDMA communication system (100). To accurately characterize coverage and loading parameters related to the CDMA communication system, parameter meshes corresponding to parameters of the CDMA communication system are generated. The parameter meshes are evaluated, either individually or in combination, to provide comprehensive information regarding the performance of the CDMA communication system. Based on the results of the evaluation, a controller (113) within the CDMA communication system (100) controls the parameters to improve call quality, loading, etc. of the CDMA communication system (100).

Claims

1. A method of controlling a communication system, the method comprising the steps of:

calculating at least one parameter mesh corresponding to a parameter related to the communication system at each x,y coordinate of a grid over an area of interest, the parameter related to the communication system comprising forward and reverse power requirements, a number of useful pilot signals and a best pilot signal;

evaluating the at least one parameter mesh to generate a control signal effecting the parameter related to the communication system; and

controlling the communication system based on the generated control signal.

2. A method of controlling a communication system, the method comprising the steps of:

calculating a plurality of parameter meshes corresponding to a plurality of different parameters related to the communication system at each x,y coordinate of a grid over an area of interest, the plurality of different parameters related to the communication system comprising forward and reverse power requirements, a number of useful pilot signals and a best pilot signal;

combining predetermined parameter meshes to generate predetermined control signals; and

controlling the communication system based on the generated predetermined control signals.

3. A method of controlling a code division multiple access communication (CDMA) system, the method comprising the steps of:

determining forward link power requirements for all base-stations in an area of interest;

determining, based on the determined forward link power requirements, the base-station which contributes the largest forward link power; and

limiting the number of mobile station connections to that base-station so that its forward link power contribution with respect to the total forward link power of all base-stations is diminished.

4. The method of claim 3, wherein the number of connections to the base-station of interest are allowed to increase based on a re-evaluation of the base-station'"'"'s effect on the communication system.
