Abstract
In some embodiments, a base station includes a service flow management module having an admission control module and a data path function module in communication with the admission control module. The data path function module is adapted to generate a first dynamic service addition (DSA) request message for a first uplink service flow in an active state to provide voice over internet protocol (VoIP) signaling. the admission control module, in response to the admission control module determining that a second uplink service flow in an admitted state for a VoIP call can be supported, is adapted to generate an admit signal, with the first and the second uplink service flows being substantially in accordance with an Institute of Electrical and Electronic Engineers (IEEE) 802.16 standard. The data path function module, in response to the admit signal, is further adapted to generate a second DSA request message for the second uplink service flow, with the second DSA message containing an amount of a reserved bandwidth for the VoIP call.
