Summa announcing release 3.6 of our NextGen HSS

Simplified roaming controls in which the PLMNs can both act as HPLMN and VPLMN.

When dealing with multi-IMSI scenarios, it is important to be able to define the HPLMN and the VPLMN of each IMSI. That means that when a sponsor IMSI is used, although the user might never connect to their HPLMN, the definition has to be clear for the HLR / HSS. The new release has a unified view for the PLMNs on the platform, simplifying the management.

Direct SMS Home Profile and Delta roaming profiles have been added to allow a better control per IMSI of the SMS home routing, and possible exceptions to the roaming profiles.

You will also now be able to deactivate a subscriber’s IMSIs, so each IMSI can individually be activated and deactivated.

A sneak preview on the next release: Adding the COMP128 and a new core implementation to better improve the performance.
