In an embodiment, a user equipment (UE) determines to initiate a communication session with at least one other UE to be arbitrated by an application server. The UE determines a type of the communication session (e.g., delay-sensitive, PTT, etc.) and/or a size of a call message to be sent by the UE for requesting initiation of the communication session by the application server. The UE selects a reverse-link channel on which to transmit the call message based at least in part upon the determined type of the communication session and/or the determined size of the call message. The UE transitions to a given state (e.g., CELL_FACH, CELL_DCH, etc.) that supports transmissions upon the selected reverse-link channel. The UE transmits the call message on the selected reverse-link channel after the UE is transitioned to the given state. |
