<p>Setting up a group (push-to-talk, PTT) communication session requiring Quality of Service (QoS) resources at an access terminal, AT, within a wireless communications system by sending a first request (i.e. a bundled message including a ReservationOnRequest message, a data-over-signaling (DoS) message, a ConnectionRequest message and a RouteUpdate message, or a non-bundled ReservationOnRequest, RoR, message), within a second (visiting) serving area, to obtain traffic channel (TCH) and QoS resources for the group communication session, the first request based on a first access terminal identifier (UATI) that identifies the access terminal, AT, within a first serving area that is separate from the second serving area; determining that the TCH resources have been allocated to the AT and that the QoS resources have not been allocated to the AT; sending a second request, in response to the determining step and within the second (visiting) serving area, that requests the QoS resources for the group communication session, the second request based on a second access terminal identifier (second - new - UATI) that identifies the AT within the second serving area; and receiving an allocation of the requested QoS resources within the second serving area in response to the second request.</p> |
