The development of 3G mobile networks is attended by revolutionary changes in the telecommunication and service technologies of mobile systems. There have been impressive rates of evolution from circuit switching (CS) to packet switching (PS) and IP protocols; from monoservice voice systems, operating on CS principles, to multiservice PS system for integrated transmission of fast data, voice, video etc. with differentiation and quality of service (QoS) control. The amount of traffic with access to broadband Internet services is rapidly increasing. The time principles of payment are substituted by accounts for data volume and quality of service. The new technologies require development of new methods of traffic theory, optimization and design. It is necessary to change from one-dimensional Erlang models for homogeneous traffic in point-to-point channels to develop the theory of the multi-dimensional distributed queues with priority service for integrated traffic in multi-point radio channels with multiple access. This article presents such new methods for the analysis of traffic, optimization and dynamic QoS control for 3rd generation mobile networks, taking GPRS systems as an example. The offered solutions are based on the development of a numerical method of balancing traffic intensities (see Markhasin, A.B., 2nd All-Union Confer. on Multiple Access Systems, pt1, p.146-52, 1999; Markhasin, A.B. and Kokoreva, E.V., Proc. VI Business-Forum "Mobile Systems'01", vol.1, pp.175-81, 2001), and also on the development of our results concerning the analysis of traffic, optimization and dynamic QoS control in integrated packet satellite and radio ATM networks (see Markhasin, IEEE Int. Conf. on Communications, p.1914-18, 2001)
