ABSTRACT:
A method and system of packet switched traffic management in a cellular telecommunications system is provided. The invention comprises a packet switched radio channel (PRCH) manager for each cell of a cellular system and a PRCH controller for each PRCH in the cell. The PRCH manager interacts with and, controls one or more PRCH controllers. The PRCH manager performs the functions of evaluating service requests, handling a PRCH admission queue and managing the active PRCHs of the cell. The PRCH controllers perform the functions of supervising ongoing traffic, controlling admission and controlling traffic congestion for each individual PRCH. The invention allows a system operator to set a maximum tolerable delay for each PRCH and a priority for each packet call. By selectively choosing the maximum tolerable delays and priorities within the system, the system operator can reduce the probability that a PRCH user is subject to unacceptable packet transmission delay.
