Abstract:
1. A method comprising: a computer system determining that access channel occupancy (ACO) in a sector of a wireless communication system meets a first threshold; the computer system determining that reverse noise rise (RNR) in the sector of the wireless communication system meets a second threshold; and responsive to determining that (i) the ACO meets the first threshold and (ii) the RNR meets the second threshold, the computer system making one or more access channel parameter adjustments for the sector in an effort to decrease occurrence of access failures in the sector, wherein the first threshold is a designated “high” level of ACO, wherein the second threshold is a designated “high” level of RNR, and wherein the one or more access channel parameter adjustments comprise an adjustment selected from the group consisting of: (a) increasing randomness of access probe transmission over time; (b) decreasing initial power for access probe transmission; (c) decreasing power steps between access probe transmissions; and (d) decreasing maximum number of access probes that a mobile station is allowed to transmit per access probe sequence.
