Huawei introduced a User Connection Boost solution for UMTS HSPA+ that doubles the number of user connections in a single UMTS cell. The first commercial deployments are in Portugal and Canada. User Connection Boost enhances bearer and radio resource sharing efficiency to greatly enhance number of simultaneously connected users. It also extends user terminal battery life, all without affecting user experience. To do so, the solution utilizes software-deployable algorithms for CPC (Continuous Packet Connectivity), E-FACH (Enhanced Forward Access Channel) and E-RACH (Enhanced Random Access Channel).
Huawei said UMTS HSPA+ continues to evolve by offering an increasing number of connections per cell. Improvements continue with uplink and downlink peak rate enhancements thanks to improved dual-carrier and high-order modulation technologies. By the second half of 2012, 134 operators in 70 countries completed commercial DC-HSDPA deployment and can now offer services for increasingly popular DC-HSDPA-capable terminals.
