PrintSmart networks for smart phones
Smartphones have made the vision of being always-on a reality. Applications such as push e-mail or instant messaging constantly transfer data to the phone, ideally all day long. In reality however, users complain about the battery of their shiny new phones being exhausted all too quickly.
The power consumption of a 3G phone that is always-on can be reduced significantly by Nokia Siemens Networks’ HSPA radio access networks. We implemented the low power consumption Cell_PCH RRC state in the first 3G release, which allows fast transition of the user device from low power consumption to high-speed data transmission, with significantly reduced signalling. In turn, this also reduces the inactivity time for the transition back to a power saving state. The introduction of the HSPA+ Continuous Packet Connectivity (CPC) feature is another step in further optimizing the power consumption of phones. With CPC, we also reduce the interference in the network and thus increase its capacity.
Optimized RRC state management and CPC are software features, which complement the superior scalability of Nokia Siemens Networks’ RNCs and I-HSPA solution with an increasing signalling load. The key to the unique signalling scalability of RNC2600 and Multicontroller is that they feature one RNC-wide resource pool, which can handle much higher practical loads than sub-RNC-level resource pools. With the flat architecture of I-HSPA, we have an ultimately distributed resource pool. Both approaches ensure the highest scalability.
Combining the optimized RRC state management and the unique capacity scalability for payload and signalling, Nokia Siemens Networks’ HSPA(+) can benefit smartphone users everywhere.
