DATA TRANSMISSION VIA A GPRS RADIO COMMUNICATION NETWORK

摘要

In a communication system, a subscriber unit includes a storage device storing an application program to determine for transmission a current reserved bandwidth and a transmission parameter based on a quality of based on a quality of service profile, and an adapter to communicate data over a wireless network (e.g., a general packet radio service network) that supports a service, satisfying a reliability requirement for the service. The adapter may dynamically adjust the transmission parameter for the transmission before retransmitting one or more packets of data, e.g., at a rate and retransmission times commensurate with the current reserved bandwidth, and the reliability requirement in addition to the a current quality of service profile, ensuring a service level which otherwise cannot be provided by an infrastructure negotiated quality of service, especially in relatively shorter flows of data.
