1. IPPATH bad configuration cause IP Iu PS RAB failure in RCN because congestion without previous alarm
2. Iu PS IPPATHs fault after new IPPATH addition
3. IuPS RAB Establishment Failure Because SGSN Assign its Resource to Other UGFU Board Which Is Not Connected with RNC
4. License cause IUPS over IP not working
5. One IU-PS link is limited because of SGSN
6. Subscriber can attach to 3G network but cannot connect to the internet (IU-PS connection)_only PS service_but not CS
