Wireless Intellegent Network (WIN)
INTRODUCTION
1. Definition
Wireless intelligent network (WIN) is a concept being developed by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. The WIN standards protocol enables a graceful evolution to an IN without making current network infrastructure obsolete.
Service differentiation and streamlined infrastructure are key factors to winning the battle of competition as customers expand and become more sophisticated and the wireless service becomes more of a commodity. To wireless carriers and service providers, this means leveraging equipment, systems and customer service initiatives across all services and markets. Wireless providers who are first-to-market with customers-oriented services will have an immense advantage in securing dominant market share. One of the vital solutions for this highly competitive and increasingly demanding market is to build a sophisticated Wireless Intelligent Network infrastructure that can flexibly support existing and new services. This approach can reduce the load on the wireless switches.
The Wireless Intelligent Network (WIN) intends to take advantage of the Advanced Intelligent Network (AIN) concepts and products developed from wireline communications. However, progress of the AIN deployment has been slow due to the many barriers that exist in the traditional wireline carriers deployment procedures and infrastructure. The success of AIN has not been truly demonstrated. The AIN objectives and directions are applicable to the wireless industry although the plans and implementations could be significantly different. In order to succeed, the technology driven AIN concept has to be reinforced by the market driven WIN services. An infrastructure suitable for the WIN contains elements that are foreign to the wireline network.
WIN, borrowing the concept of AIN, is viewed to bring competitive edges in terms of:
Holistic approach to service deployment
Mobility services beyond wireline AIN
Reduced time for service deployment
Multiple vendor expertise
Increased customization
Computerized service creation and implementation tools.
However commercial AIN services have not proven successful. There have been doubts that AIN might only theoretically address the carrier s needs.
2. Overview
Today's wireless subscribers are much more sophisticated telecommunications users than they were five years ago. No longer satisfied with just completing a clear call, today's subscribers demand innovative ways to use the wireless phone. They want multiple services that allow them to handle or select incoming calls in a variety of ways.
Enhanced services are very important to wireless customers. They have come to expect, for instance, services such as caller ID and voice messaging bundled in the package when they buy and activate a cellular or personal communications service (PCS) phone. Whether prepaid, voice/data messaging, Internet surfing, or location-sensitive billing, enhanced services will become an important differentiator in an already crowded, competitive service-provider market. Enhanced services will also entice potentially new subscribers to sign up for service and will drive up airtime through increased usage of PCS or cellular services. As the wireless market becomes increasingly competitive, rapid deployment of enhanced services becomes critical to a successful wireless strategy.
