This new technology may benefit several mobile users. Nokia Siemens Networks is believed to have effectively performed the world’s first call by means of a network technology called ‘continuous packet connectivity’ (CPC). This new technology claims to surge the battery life of devices.
Once integrated into an operator’s HSPA+ radio access network, CPC can facilitate 3G users to benefit from the notably longer device battery life. CPC can also denote up to 100 percent more battery life when handsets are utilized for data applications, and up to 50 percent during voice calls. The CPC data call was apparently done by means of network gear from Nokia Siemens Networks and a device delivered by Qualcomm via the QSC6295 chipset.
“Nokia Siemens Networks is focused on innovations that benefit both operators and end-users. With CPC, subscribers will enjoy an improved mobile data experience, while operators will benefit from enhanced network capacity — even with heavy smartphone use — due to less interference in the radio connection, not to mention higher revenues due to increased usage of the service,” commented Tommi Uitto, head of Network Systems product management at Nokia Siemens Networks,
“At Qualcomm, we are committed to driving the evolution of technology features that provide the maximum benefit to end-users. The CPC feature further enhances the HSPA+ mobile broadband experience for end-users by allowing them to enjoy these services without worrying about device battery life,” remarked Alex Katouzian, vice president of product management for Qualcomm CDMA Technologies.
Throughout the extensive HSPA data sessions, there are usually lengthy durations of unoccupied time between transmissions of data packets, during which a handset carries on utilizing battery. The CPC attribute of 3GPP Release 7 supposedly utilizes the ‘discontinuous transmission and reception’ technique to close down the device’s transmitter and receiver during the idle stages to decrease power use. It seems to have no consequence on the authentic data rates experienced by the mobile user.
Nokia Siemens Networks’ Flexi Base Station and radio network controller is compatible with the CPC feature having an easy software update.
