IMS 5.0 (FMC3.1) IMS 6.1 (FMC4.0)• The performance of the SPDF (PCS-5000 V3.1) has been

increased • The performance of the P/I/S – CSCF and HSS measured in the

load tests (TM) FMC4.0 with HCM activated has reached the IMS5.0 values

• The performance of the HiQ4200 R13 FP1 measured in the load tests (TM) FMC4.0 with HCM activated has reached the HiQ4200 R12 values

• The performance of the BGW is the same as for FMC3.1• The EtE performance of the IMS6.1 configuration based on the

OSP HW deployment can serve appr. 400 000 subs according to the FT TM. The first bottleneck in this configuration is the BGW.
