Embodiment Construction

[0037] figure 1 A typical GPRS / UMTS mobile network is shown. Mobile station 110 communicates with the network by receiving and transmitting signals from / to base transceiver station (BTS) 120 . Each BTS 120 communicates with a Base Station Controller (BSC) 125 which controls one or more BTS devices. Multiple BTS devices and BSC devices are often collectively referred to as a base station system (BSS) 130 . In addition, a radio access network (RAN) 135 includes a BSS and transmits signals from / to the MS device 110 over the air.

[0038] Through a BSS virtual circuit (BSSVC) 131 , the BSC 125 communicates with a Serving GPRS Support Node (SGSN) 140 that performs mobility and data session management for the mobile station 110 . SGSN 140 communicates with Gateway GPRS Support Node (GGSN) 150 through GPRS core network 145 . GGSN 150 acts as a gateway between GPRS core network 145 and external packet data networks, such as the Internet 155 . The GGSN 150 communicates with a plur...

Abstract

A system and method for the implementation of fine-grained quality of service in a mobile telecommunications environment uses an Auto-IP Policy Decision Point (PDP) to determine what traffic optimizations actions should be taken in reaction to various network conditions. The Auto-IP PDP uses as inputs information from a Gb interface probe to determine the user identification of an IP data flow, information from the radio access network (RAN) network management system (NMS) regarding network congestion. The cell traffic information is passed onto a traffic analysis and processing engine, the Auto-IP PDP which maps the real-time traffic information into an n-dimensional traffic model. An automated policy decision guiding algorithm is executed on the n-dimensional traffic model and selects policy based on the traffic and cell congestion conditions, without human intervention. Additionally, a consistency check is performed to ensure that new policies are consistent with existing policies. The policy decision outcome is forwarded to the Auto-IP Traffic Optimizer that acts on the network at a point in the network (Gi) that is different from where traffic problem occurs in the RAN. The Auto-IP Traffic Optimizer implements the decisions of the Auto IP-PDP by performing traffic shaping, TCP window clamping or other traffic optimization procedures on a cell-by-cell basis.

Description

technical field [0001] This application claims the benefit of priority of US Provisional Application No. 60 / 495,308, filed August 14, 2003, entitled "Dynamic Network Management In A Mobile Environment." [0002] The present invention relates to the provision of data services in wireless telecommunication networks. More specifically, the present invention relates to a method and system for dynamically managing network configuration and automatically optimizing network traffic to efficiently use existing wireless networks for voice and data traffic. By selectively applying different optimization techniques, such as traffic shaping of traffic to the radio access network, the overall load in the cell can be reduced and thus the network performance can be increased. Background technique [0003] In telecommunication systems such as second-generation (2G) mobile networks, capacity constraints have led to a decline in average revenue per user, thereby motivating mobile operators t...
