Claim of US Patent No. 9,661,636

1. A method of operating a wireless access node to facilitate voice over long term evolution (VoLTE) communication sessions,
the method comprising:
exchanging VoLTE packets with a wireless communication device during a VoLTE communication session;
monitoring a number of hybrid automatic repeat request (HARQ) retries requested by the wireless communication device during
the VoLTE communication session;

comparing the number of HARQ retries to a threshold value; and
if the number of HARQ retries falls below the threshold value, dropping a percentage of the VoLTE packets to achieve an overall
percentage of packet loss for the VoLTE communication session based on the number of HARQ retries.
