Nokia refers to HSPA+ by the name I-HSPA or Internet-HSPA.

According to their whitepaper:
- 3G operators who have deployed I-HSPA have flat network architecture similar to LTE/SAE in place, and can thus cost-efficiently introduce LTE/SAE.
- 3G operators with a deployed WCDMA/HSPA network can migrate
directly to LTE/SAE. Migrating to the flat network architecture of
Internet High Speed Packet Access (I-HSPA) may also be beneficial
because it accommodates LTE/SAE’s flat IP-based network architecture while supporting legacy WCDMA/HSPA handsets. The operator can thus enjoy the transport and network scaling benefits immediately and easily upgrade the network to LTE/SAE later. - Greenfield and CDMA operators can introduce LTE/SAE networks
directly or follow one of the above paths. GSM/EDGE may be a good choice for strategies more immediately focused on voice centric business. Operators opting to take the I-HSPA path can capitalize on the ecosystem of HSPA terminals, benefit from the flat architecture today, and quickly optimize mobile broadband performance.
