Abstract: Packet communications may be provided over a wireless channel between a radio network node and a wireless terminal. The wireless terminal may include a jitter buffer configured to reduce jitter resulting from different delays of data packets received at the wireless terminal. Operation of the jitter buffer for the wireless terminal may be emulated responsive to data packet transmissions from the radio network node to the wireless terminal. Responsive to emulating operation of the jitter buffer for the wireless terminal, a parameter of emulated operation of the jitter buffer may be provided including at least one of an emulated late packet loss occurrence, an emulated time scaling occurrence, an emulated jitter buffer fill level, and/or an emulated jitter buffer fill level threshold. Related network nodes are also discussed.
