1. A method comprising:

  • a radio access network (RAN) determining a comparative signal-strength measure based on a comparison of a signal-strength measurement for a candidate sector to a signal-strength measurement for at least one active sector in an active set of a wireless communication device (WCD);

    determining, by the RAN, whether or not the comparative signal-strength measure is less than a first threshold;

    if the comparative signal-strength measure is less than a first threshold, then the RAN;

    determining a comparative codec-quality measure based on a comparison of a first codec associated with the candidate sector to a second codec associated with the active sector;

    determining whether or not the comparative codec-quality measure is greater than a second threshold; and

    if the comparative codec-quality measure is greater than a second threshold, then sending a message to the WCD that indicates to add the candidate sector to the active set; and

    otherwise, refraining from adding the candidate sector to the active set.
