Switch-based C/I measurement
First Claim
1. A method for making switch-based C/I measurements for a wireless network including a plurality of cell sites, comprising steps of:
- (a) designating a first cell site of the plurality of cell sites as a cell-under-test (CUT) site, and sectors of other cell sites as measurement sectors;
(b) configuring a set of system-unique analog frequencies and a set of system-unique dedicated control channel (DCCH) frequencies corresponding to the CUT site;
(c) broadcasting from the CUT site carrier signals at the set of system-unique analog frequencies and interference signals at the set of system-unique DCCH frequencies;
(d) measuring downlink signal strengths of the carrier signals at mobile stations located within an area serviced by the CUT site;
(e) measuring signal strengths of the interference signals within areas serviced by the measurement sectors;
(f) recording the signal strengths of the carrier and interference signals measured is steps (d) and (c); and
(g) designating another cell site of the plurality of cell sites as the CUT site and repeating steps (b) through (f).

Abstract
A system and method for generating a switch-based C/I matrix for a wireless network is provided. A cell-under-test (CUT) may broadcast system unique carrier and interference signals to mobile stations serviced by the CUT and mobile stations serviced by measurement sectors of other cells in the wireless network. The mobile stations make downlink signal strength measurements, and transmit the signal strength measurements to the corresponding sectors and CUT that service the mobile stations. The measurement sectors may be further configured to measure signal strength of the interference signals transmitted from the CUT on the uplink. The signal strengths are then processed to generate the switch-based C/I matrix.
