A wireless network and serviced mobile station manages VOIP telephony calls
by incorporating control information into VOIP datagrams. The control
information includes an indication of the data rate of the VOIP payload of
the VOIP datagram, the quality of the VOIP payload, requested data rates
for subsequent VOIP datagrams, and whether the VOIP payload contains a
"silent" VOIP payload. To avoid conflicting with particular datagram
requirements, the control information is inserted into the VOIP datagram
between the VOIP datagram and the VOIP payload. A base station servicing
the wireless link may override the requested data rate and/or the
commanded data rate in order to manage its available wireless bandwidth
among a plurality of mobile stations. The frame quality indicator may be
set by the servicing physical/mac/link layer(s) of the base station or
mobile station to indicate that the VOIP payload was not correctly
received.
