ABSTRACT:
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.
