The paper considers end-to-end quality of service (QoS) aspects of the upcoming PoC (Push-to-talk over Cellular) service. Derived from the quality and performance requirements on signaling and media flows of this service, GPRS mechanisms and service parameters are discussed, which have significant influence on the end-user experience of the service. The impacts of mobile network elements are analyzed in terms of delay and bandwidth along the end-to-end transport path of GPRS networks. The paper concludes with an outlook on service quality enhancements, which will be possible with the deployment of the service in Enhanced GPRS and UMTS networks.
