Abstract

A traffic simulator for a cellular radio telecommunications network. The traffic simulator includes a function handler which generates a plurality of basic call functions performed by mobile stations (MSs) over an air interface link with the network. A sequence handler utilizes the basic functions to generate a plurality of call sequences, and a traffic mix handler utilizes the plurality of call sequences to generate an overall traffic mix. A MS handler includes a plurality of MS state machines for different types of MSs and a database of MS properties. The MS handler interfaces with the basic functions to generate realistic inputs to the sequence handler. A cells handler includes a database of cells in the network and parameters relating to radio conditions. The cells handler also interfaces with the basic functions to generate realistic inputs to the sequence handler. A traffic repository may inject recorded real mobile station traffic into the traffic mix. A connection manager sends the traffic mix to external network components, and a graphical user interface (GUI) enables an operator to interface with the traffic simulator and generate specified traffic scenarios.
