hi
thanks for reply.
i use test_udp script and mannul to write program for umts euran. it runs fine.
but there is no communication between ue1 and base station. even i put the sink
at ue1. but the trace file show only communication between base-station, fixed
node and rnc. but no message send to ue1. program i use is
global ns
