Also noticed that TLLI changes from Activate PDP context. This TLLI is based on TMSI/P-TMSI Upto Attach complete procedure I have different TLLI. For setup I have BSC, SGSN on eth0 and eth0:1 respectively and GGSN on eth1 ( I have external network adapter). Can anybody suggest something why I am not getting pdp deactivation. regards Josh
