Nokia Siemens Networks combines three powerful WCDMA software features to improve profitability of mobile broadband
Nokia Siemens Networks has introduced its Liquid Radio WCDMA software suite to boost performance of existing WCDMA networks. Building on the capabilities of the company’s Liquid Net, the advanced software combines three powerful and complementary features. This approach aims to deliver faster data uploads and extract the full benefit from network resources and smartphone capabilities.
The feature set helps operators improve customer satisfaction and cut churn while increasing revenue from greater 3G availability. The three features are Continuous Packet Connectivity (CPC)*, Multi-Band Load Balancing (MBLB)** and Quality of Service (QoS) differentiation***.
The increased adoption of smartphones to share videos and images via social media and cloud storage means that data being sent from devices to the network now accounts for 20% of total network traffic. Because of this, operators are experiencing a serious challenge to provide more ‘uplink’ capacity. Continuous Packet Connectivity helps operators use radio network resources more efficiently by reducing interference. It does this by turning off transmitters in mobile devices when no data needs to be sent. CPC enables the network to support five times more users and four times more uplink throughput. As a result, operators can enable fast data uploads and provide a longer battery life for users’ smart devices.
Many WCDMA networks are multi-layered – meaning that operators are using two or more frequency bands such as 900 MHz and 2100 MHz – to provide the 3G service. By balancing traffic evenly between an operator’s available spectrum, Multi-Band Load Balancing prevents one frequency band from becoming overloaded while another is underused. This ensures optimal use of the network capacity across all available 3G bands and helps operators fully benefit from their investments. MBLB creates up to 20% more available network capacity from existing hardware resources. In trials in London during summer 2012, an operator used MBLB and corresponding services to successfully balance data traffic in its network and thus enable higher data speeds for subscribers.
In cases where traffic begins to exceed network capacity, even after CPC and MBLB have been implemented, a third feature of the WCDMA software suite, QoS differentiation, comes into play. As well as supporting time critical data traffic, QoS differentiation makes it possible to have up to 50% more users per network cell, which can reduce operational costs by 30%. Overall, the feature helps raise efficiency, reduce wasted capacity and improve the user experience.
“Our WCDMA software suite gives operators the tools they need to build outstanding, personalized solutions for their subscribers while boosting network performance, capacity and quality at the same time,” said Keith Sutton, head of the WCDMA business line, Nokia Siemens Networks. “This way, they can meet users’ demands for high-quality high performance services.”
Nokia Siemens Networks’ feature introduction services enable operators to fully utilize the WCDMA software suite. The company’s experts trial each feature in a small area of the network to ensure optimal settings prior to full rollout.
To help operators monetize their investments in multi-layered WCDMA networks, the feature set can also be combined with Nokia Siemens Networks’ other WCDMA features and services for trialing, configuring and monitoring network performance. CPC coupled with Flexi Direct****, the company’s flat architecture for 3G, can enhance smartphone experience by eliminating signaling bottlenecks and maximizing WCDMA capacity. MBLB can help ensure that users enjoy the full benefits of Nokia Siemens Networks’ Dual Cell HSPA+ feature*****. This feature allows operators to transmit data from two cells simultaneously, thus doubling peak rates. MBLB automatically allocates any device that supports Dual Cell HSPA+ to an appropriate frequency band.

* Continuous Packet Connectivity (CPC) is a 3GPP feature supported by the latest mobile devices. Without CPC, control signaling is continuous, creating interference that degrades the uplink capacity. With CPC, uplink control channel signaling is only transmitted when the mobile device has data to send. This reduces interference and increases uplink capacity. Operators can implement CPC with a simple software upgrade to the radio network.

** Multi-Band Load Balancing (MBLB) uses a sophisticated algorithm to decide which frequency band a device connects to. The decision is made based on a number of criteria including capabilities and speed, the service used, the load and channel quality in the source and target cells, and the signal strength of the target cell. Developed by Nokia Siemens Networks, MBLB is device independent.
*** Quality of Service (QoS) differentiation works by dynamically differentiating traffic when the network becomes congested and enforcing policy rules based on time of day, device type, data volume, location and more. QoS differentiation ensures that the most time critical services and customers are served first. Nokia Siemens Networks offers QoS differentiation and unique application awareness using its comprehensive QoS differentiation capabilities that have already been deployed successfully in more than 20 networks.
**** Flexi Direct, Nokia Siemens Networks’ flat architecture for 3G, enables simpler operations, enhanced performance and higher scalability. Operators can cost-efficiently scale their networks to address rapidly growing traffic volumes. The 3GPP-standardized flat architecture is compatible with all HSPA devices, and paves the way to LTE with which it shares an identical architecture.
***** Dual Cell HSPA+ allows operators to transmit data from two cells simultaneously, thus doubling peak rates.
