It’s easy to understand that happy customers are those who get high data speeds and connectivity everywhere with their mobile devices. That’s why mobile operators are always looking for ways to get more throughput and coverage from their WCDMA networks. Doing just this, China Unicom recently conducted a trial with Nokia using the Dynamic HSUPA BLER feature in its live network and was rewarded with a WCDMA performance that delivered a whopping increase in data throughput.
Here’s how the feature works. High-Speed Uplink Packet Access (HSUPA)* is a 3G data protocol, and Block Error Ratio (BLER) is a measure of data transmission quality. With this new feature, operators can define a variety of BLER targets for different radio conditions and traffic types, and as conditions change, the software automatically adjusts the BLER target to improve HSUPA cell throughput and increase coverage.
What does this feature mean to mobile customers? First, they enjoy faster speeds for data uplink to the mobile network, as well as higher throughput when they are connecting at the edge of a cell’s coverage area. This means they can upload their photos and videos to social media faster as well as store them in the cloud. And second, higher quality data transmissions reduce power demand on the device which extends battery life, an important advantage for smartphone users.
For China Unicom, an operator serving around 130 million 3G subscribers**, the new capability is a good fit for the company’s goal of continuously improving the customer experience. “We measured a 30% HSUPA throughput increase with the Nokia Dynamic HSUPA BLER feature in our field trials. This means faster uploading speed and better cell-edge throughput for our end customers,” said Mr. Hou Wenjun, General Manager of Shanghai Unicom Network Optimization Center, China Unicom. The field trial was a cooperative effort of Nokia Networks and the operator. It showed that all HSPA calls under the same cell can get better HSUPA throughput – a significant improvement.
The Dynamic HSUPA BLER feature is available as part of the HSPA RU40 software release.
