ABSTRACT:
A method of selecting a voice channel in a radio telecommunications network. The method begins by seizing a first digital traffic channel (DTC) having a carrier signal strength (C) and an interference strength (I), and calculating an expected ratio of the carrier signal strength to the interference strength (C/I) on the first DTC. From this calculation, it is determined whether the first DTC is disturbed. This is followed by utilizing the first DTC for a call upon determining that the first DTC is not disturbed, and seizing a second voice channel upon determining that the first DTC is disturbed. The second voice channel may be a second DTC or may be an analog voice channel (AVC). If a second DTC is seized, the C/I is determined for the second DTC, and the DTC with the higher C/I is retained. If the second DTC is also disturbed, another reselection and comparison may be performed. Reselections continue until a channel with good C/I is found, or a maximum number of reselections is performed.
