Hi all;
Need some help about handover between 2G to 3G. In our network, we keep the Ues in 3G in idle mode. We dont let the Ue search 2G network and with the parameters, when the Ue wants to make a voice call, The Ue immidietly enter the compress mode to handover to 2G network. But, this does not happen. When i take a log with tems, in layer 3 signalling, i see that the Ue enter the compress mode immidietly but it can not make handover to 2G.
Our parameter settings are below;
for Nokia 2G Sites;
Min CPICH Ec/Io Level=0,5
Direct Access Ec/Io Threshold=0,5
QSRI=7
QSRP=7
FDD offset=-32
FDM=-20
for Huawei 3G sites;
INTERRATCSTHD2DRSCP=-30
INTERRATCSTHD2FRSCP=-30
InterRATNCovHOCSThd=20
INTERRATCSTHD2DECN0=-3
QRXLEVMIN=-50
i am waiting your valuable reply;
thanks for all,
kadir
