Abstract
Abstract Carriers (51) in a communication system (10) are prioritized (70) according to their usability. The carriers (51) that are below a usability threshold are placed on an ingress list (122). Those that exceed the threshold are placed on a preferred list (121). The carriers (51) on the preferred list (121) are then ranked (76) according to their word error rates (WER) and signal quality (SQ). The carriers (51) on the ingress list (122) have their usability re-checked periodically and may be transferred to the preferred list (121) if their usability does not again drop below threshold during a pre-set time period.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
A method comprising the steps of: measuring a usability of a number of carriers in a communication system to determine if a usability of any of the number of carriers is below a threshold; for each one of the number of carriers which are below the threshold, placing the one of the number of carriers on a bottom of an ingress list after it has been evaluated to be below the threshold, wherein the bottom of the ingress list means latest in time for which ingress is detected; and for each one of the number of carriers on the ingress list, promoting the one of the number of carriers on the ingress list to a preferred list after a time on the ingress list for that one of the number of carriers is greater than a maximum predetermined time.
Claim 2
Independent Claim
139 words
A method comprising the steps of: measuring a usability of a number of carriers in a communication system to determine if a usability of any of the number of carriers is below a threshold; for each one of the number of carriers which are below the threshold, placing the one of the number of carriers on a bottom of an ingress list after it has been evaluated to be below the threshold, wherein the bottom of the ingress list means latest in time for which ingress is detected; and for each one of the number of carriers on the ingress list, promoting the one of the number of carriers on the ingress list to a preferred list after a time on the ingress list for that one of the number of carriers is greater than a maximum predetermined time.
Claim 3
Dependent Claim
26 words
A method according to claim 1 wherein the step of measuring a usability comprises measuring each of the number of carriers at continuously at periodic intervals.
Claim 4
Dependent Claim
41 words
A method according to claim 1 wherein the method further comprises ordering all of the number of carriers having a usability above the threshold in a preferred list, wherein the order is according to a rank of a word error rate.
Claim 5
Independent Claim
143 words
A method comprising the steps of: measuring a usability of a number of carriers in a communication system continuously at periodic intervals to determine if a usability of any of the number of carriers is below a threshold; for each one of the number of carriers which are below the threshold, placing the one of the number of carriers on a bottom of an ingress list after it has been evaluated to be below the threshold, wherein the bottom of the ingress list means latest in time for which ingress is detected; and for each one of the number of carriers on the ingress list, promoting the one of the number of carriers on the ingress list to a preferred list after a time on the ingress list for that one of the number of carriers is greater than a maximum predetermined time.
Claim 6
Independent Claim
143 words
A method comprising the steps of: measuring a usability of a number of carriers in a communication system continuously at periodic intervals to determine if a usability of any of the number of carriers is below a threshold; for each one of the number of carriers which are below the threshold, placing the one of the number of carriers on a bottom of an ingress list after it has been evaluated to be below the threshold, wherein the bottom of the ingress list means latest in time for which ingress is detected; and for each one of the number of carriers on the ingress list, promoting the one of the number of carriers on the ingress list to a preferred list after a time on the ingress list for that one of the number of carriers is greater than a maximum predetermined time.
