Abstract:
A method of selecting a voice channel in a radio telecommunications network, said method comprising the steps of:seizing a first digital traffic channel (DTC) having a carrier signal strength (C) and an interference strength (I);calculating an expected ratio of the carrier signal strength to the interference strength (C/I) on the first DTC;determining whether the first DTC is disturbed by determining whether the expected C/I on the first DTC is less than a predetermined threshold;utilizing the first DTC for a call upon determining that said first DTC is not disturbed;seizing a second DTC upon determining that said first DTC is disturbed;calculating an expected ratio of the carrier signal strength to the interference strength (C/I) on the second DTC;comparing the expected C/I on the first DTC with the expected C/I on the second DTC to determine which DTC has the higher expected C/I; andutilizing the DTC with the higher expected C/I for the call.
