CELLULAR NETWORK TRAFFIC SIMULATOR.

摘要

A traffic simulator (13) for a cellular radio telecommunications network. The traffic simulator includes a function handler (62) which generates a plurality of basic call functions performed by mobile stations (MSs) over an air interface link with the network. A sequence handler (63) utilizes the basic functions to generate a plurality of call sequences, and a traffic mix handler (64) utilizes the plurality of call sequences to generate an overall traffic mix. An MS handler (56) includes a plurality of MS state machines for different types of MSs and a database of MS properties. The MS handler (56) interfaces with the basic functions to generate realistic inputs to the sequence handler (63). A cells handler (58) includes a database of cells in the network and parameters relating to radio conditions. The cells handler (58) also interfaces with the basic functions to generate realistic inputs to the sequence handler (63). A traffic repository (57) may inject recorded real mobile station traffic into the traffic mix. A connection manager (52) sends the traffic mix to external network components, and a graphical user interface (GUI)(51) enables an operator to interface with the traffic simulator and generate specified traffic scenarios.
