Abstract
Several different methods are described herein for reducing the setup time needed to establish a media flow (e.g., packet-based voice communications) between two devices (e.g., two GPRS UEs, GPRS UE/server, GPRS UE/WLAN UE). In one embodiment, the method minimizes the setup time for establishing IMS telephony using pre-provisioned resources--reserve at INVITE. In another embodiment, the method minimizes the setup time for establishing IMS telephony using pre-provisioned radio resources--reserve at ANSWER. In yet another embodiment, the method minimizes the setup time for establishing IMS telephony using pre-provisioned radio resources--reserve according to most demanding codec properties. All of these methods and in particular a UE and PS-CN may use the network initiated ISPCA method to reduce the setup time needed to assign packet-based bearers which are required to establish the media flow.
