HSL Launch Femtocell Solution Powered by the Cloud

Edinburgh, Scotland, 10th February 2011

HSL are pleased to announce a service to combine femtocells and cloud computing to deliver a highly economical, scalable and secure femtocell network for mobile operators.

The HSL FemtoNet Cloud service employs network elements - security gateway, BSC and TRAU - to support the HSL Femtocell, coupled with elastic computing resources from AWS, one of the largest providers of cloud computing. This allows the resources employed in delivering mobile services over the femtocell network to expand and contract as user demand for services increases and decreases, for example during the day and night. Additional resource is automatically added as required to meet demand. Where surplus resource exists it is automatically removed. The result is a highly economical femtocell network with only sufficient resources being used at any given point, without impacting the ability to immediately scale to meet demands.

Femtocells located in the homes and offices of users connect via the Internet to Cloud in order to gain access to their operator's network. Mobile operators connect with Cloud via standards-based A and Gb interface links, enabling their subscribers to gain access to their network when using a femtocell connected to Cloud.

The Cloud service is an alternative to the operator hosting the required network elements within their own exchange sites while maintaining control over their femtocell network.

Cloud is part of the HSL FemtoNet range of managed services for operators using the HSL Femtocell for their 2G and 3G mobile subscribers. The range of managed services includes HSL FemtoNet Integrated, Outsourced and the latest addition, Cloud.

The HSL FemtoNet managed service can be used to rapidly get to market with a femtocell solution without significant capital expenditure (CAPEX) or high operating expenditure (OPEX). For the use of Cloud mobile operators will be charged a monthly fee per femtocell/month and data transfer charges.

NOTES FOR EDITORS

GSM 2G/2.5G/2.75G femtocells allow mobile service to be provided to both 2G and 3G subscribers. This ability is not available with 3G femtocells, which are only capable of providing mobile service to 3G subscribers. All GSM mobile telephones have the ability to use 2G or 3G networks and by default are configured by their mobile operator to use a 2G network when no 3G network is available.
