This paper describes the network architecture of LTE systems.On this basis
it designs the setup of the dedicated bearer in the process of the Packet Data Network(PDN) connection establishment and tests and simulates the implementation of the established dedicated bearer with the Standard Description Language(SDL) and Tree and Tabular Combined Notation(TTCN)
generating its Message Sequence Chart(MSC).Then
it compares the simulation results with the protocol specifications for conformance verifitcation.This test procedure has been applied to the development of LTE wireless integrated test instruments.
