A method for a remote terminal (116, 134a-134n, 201) of a wireless communications network (110, 130, 210), comprising: receiving respective data communications packets from one or more interface devices (144a-144n, 154a-154n, 205a-205n, 207a-207n, 208) associated with the remote terminal (116, 134a-134n, 201); capturing a one session request message from one of the interface device(s) (144a-144n, 154a-154n, 205a-205n, 207a-207n, 208) for initiation of a setup process to establish a first communications session over the wireless communications network (110, 130, 210); parsing the one session request message to obtain session parameters regarding the first communications session; determining inroute bandwidth requirements for the first communications session based at least in part on the session parameters; initiating a bandwidth reservation process to obtain inroute bandwidth allocations to satisfy the inroute bandwidth requirements for the first communications session, wherein each of the inroute bandwidth allocations seamlessly incorporates real time flows with existing non real time flows at the link layer, wherein both the real time data flow and non real time data flow use the same physical layer burst forms; holding the session request message until completion of the bandwidth reservation process; upon completion of the bandwidth reservation process, transmitting the one session request message to a session controller at a core node of the wireless communications network (110, 130, 210), wherein the one session request message is held by the remote terminal (116, 134a-134n, 201) and not transmitted until completion of the bandwidth reservation process; and completing the setup process with the core node to establish the first communications session. receiving respective data communications packets from one or more interface devices (144a-144n, 154a-154n, 205a-205n, 207a-207n, 208) associated with the remote terminal (116, 134a-134n, 201); capturing a one session request message from one of the interface device(s) (144a-144n, 154a-154n, 205a-205n, 207a-207n, 208) for initiation of a setup process to establish a first communications session over the wireless communications network (110, 130, 210); parsing the one session request message to obtain session parameters regarding the first communications session; determining inroute bandwidth requirements for the first communications session based at least in part on the session parameters; initiating a bandwidth reservation process to obtain inroute bandwidth allocations to satisfy the inroute bandwidth requirements for the first communications session, wherein each of the inroute bandwidth allocations seamlessly incorporates real time flows with existing non real time flows at the link layer, wherein both the real time data flow and non real time data flow use the same physical layer burst forms; holding the session request message until completion of the bandwidth reservation process; upon completion of the bandwidth reservation process, transmitting the one session request message to a session controller at a core node of the wireless communications network (110, 130, 210), wherein the one session request message is held by the remote terminal (116, 134a-134n, 201) and not transmitted until completion of the bandwidth reservation process; and completing the setup process with the core node to establish the first communications session.
