Enhanced capacity, quality and services with new Nokia software
June 02, 1998
At CommunicAsia 98, Nokia launches a new Base Station Subsystem (BSS) software release for GSM networks, the Nokia BSS7. This release provides operators with a number of flexible network configurations, making it easier to build and expand networks and optimise network investment.
Nokia Intelligent Frequency Hopping (IFH) is now available with the BSS7 release. Building on the proven Nokia Intelligent Underlay-Overlay (IUO) solution, Nokia IFH combines the best of two solutions by adding frequency hopping to the Nokia IUO two-layer structure. This solution allows an even more aggressive frequency reuse pattern to boost capacity while maintaining quality, producing additional capacity gains of up to 70% compared to a conventional network.
A new feature in the Nokia BSS7 release will facilitate implementation of Nokia IUO in dual band networks, allowing maximum capacity from a combination of Nokia Soft Capacity and Nokia Dual Band solutions. Nokia's dual band solution allows both GSM 900 and 1800 transceivers (TRXs) to be equipped within one Base Transceiver Station (BTS) cabinet, providing savings in site cost, transmission, hardware, operation & maintenance, and implementation costs. The Nokia Dual Band network is complemented by the new Nokia 6150 Dual Band mobile phone, scheduled for volume deliveries in the third quarter of this year.
In some high-traffic areas, such as airports, traffic peaks caused by bursts of location update request signals or short message service traffic can cause temporary congestion. The Stand-alone Dedicated Control Channel (SDCCH) Allocation feature included in the Nokia BSS7 release enables one free traffic channel to be changed automatically to suit the immediate capacity needs.
Operators can further increase traffic within the business-user market segment by offering new high-speed data services now available with the Nokia BSS7 software, without any hardware modifications to the base station. The High-Speed Circuit Switched Data (HSCSD) feature provides accelerated data rates for multiple time slot applications such as e-mail, file transfer and Internet browsing.
Quality is becoming increasingly important to end-users, and therefore has greater impact on operator profitability in the acqusition and retention of subscribers. In addition to the quality improvements resulting from increased network capacity, call quality can be improved with the Nokia Acoustic Echo Cancellation (AEC). With Nokia BSS7 software, this cost-effective solution is now available for Half Rate (HR) networks in addition to the existing Enhanced Full Rate (EFR) functionality.
Once sufficient capacity and quality have been established, the next step in network expansion is the introduction of new services to increase traffic. A cell broadcast centre interface included in the Nokia BSS7 release gives operators centralised control to easily transmit messages, such as traffic jams and weather warnings, throughout a cell. This is done simply through an open interconnection between the Nokia Base Station Controller (BSC) and the cell broadcast centre.
Additional features in the Nokia BSS7 software release include BSC handover support for enhanced coverage capabilities, as well as improvements for use in microcellular networks.
Headquartered in Finland, Nokia is a broad-scope telecommunications company supplying mobile phones, mobile and fixed telecommunications networks, data communications solutions, multimedia terminals and computer monitors. With sales in 130 countries, net sales totaled FIM 52.6 billion ($9.8 billion) in 1997. Nokia, listed on NYSE (NOK.A), employs more than 38,000 people worldwide.
