Some embodiments provide a method and technique for explicitly indicating the start of a communication session within an Unlicensed Mobile Access (UMA) network or Generic Access Network (GAN). To facilitate the explicit indication of the start of the communication session, some embodiments replace the first DIRECT TRANSFER message exchanged between a user equipment (UE) and network controller of the UMA network or GAN with a new message, the GA-RRC INITIAL DIRECT TRANSFER message. Some embodiments also provide a method and technique to activate a communication channel prior to performing handover from a first licensed wireless communication network to the UMA network or GAN. In this manner, some embodiments perform a more efficient and seamless handover from the licensed wireless network as the delay resulting from the handover is minimized by performing the channel activation procedure prior to the handover.
