Wireless Intelligent Network ABSTRACT: The motive of WIN is to drive “IN” capabilities in the wireless networks. WIN is defined as an architecture that separates the service logic and feature functionality from the wireless network switch and places that functionality in other platform of network. WIN paradigm is the key to helping service providers offer new enhanced services at fair rate.

Overview Intelligent Network (IN) i. IN is an architectural concept in the distributed environment. ii. Notable success is achieved in the U.S. long distance telephone industry and virtual private network services contributed strongly to growth in traffic & revenue.

Overview Wireless Intelligent Network(WIN) i. Not only are subscribers insisting on more functionality, not only are subscriber bases growing at tremendous rate, but as subscribers become increasingly accustomed to using wireless phone. ii. Equivalent vendors have not been able to keep up with request for new triggers and protocol that the market demand in order to provide enhanced service. iii. Rapid creation and deployment of services has become the hallmark of IN.

What is Wireless Intelligent Networking? An Evolving Network Architecture Enhanced Mobile Services New Capabilities Intelligent Networking Features Controlled Outside the Switch Defined for Wireline and Wireless Networks

Intelligent Network Characteristics Introduce new services rapidly Provide service customization Establish vendor independence Create open interfaces

Network Evolution Plain Old Telephone Services Stored Program Control Common Channel Signaling Network Advanced Common Channel Signaling Network Intelligent Network

IN Architecture (IN/1): Telcordia Technologies developed the concept of Intelligent Network 1 (IN/1).

AIN Architecture It has several advantages over older Intelligent Network Architecture.

Functional Components of WIN:

Mobile Switching Center(MSC) It is Service Switching Point in the IN. Switching function portion of the network. Service Control Point (SCP) Controls service delivery to subscribers. Intelligent Peripheral(IP) Gets information directly from subscribers, translates to data and hands it off to another element in the network like SCP. Functional Components of WIN:

Signal Transfer Point(STP) This is packet switch in signaling network. Handles distribution of control signals between different elements in the network. STP concentrates link traffic for the network. Location Registers Supplements MCS with information about subscribers. 1. Visitor Location Register(VLR) 2. Home Location Register(HLR)

WIN Services a.Hands-Free, Voice-Controlled Services. b.Voice Controlled Dialing (VCD) c.Voice-Controlled Feature Control (VCFC) d.Voice-Based User Identification (VUI) e.Incoming Call-Restriction/Control f.Calling Name Presentation (CNAP) g.Password Call Acceptance (PCA) h.Selective Call Acceptance (SCA)

WIN Services(cont.) i.Short Message Service (SMS) j.Speech-to-Text Conversion (STC) k. Billing, Prepaid Cellular

Stand-Alone HLR: The first step in a WIN Strategy

An SCP/HLR : The second step in WIN Strategy

Attributes of WIN Products Ability to distribute control during call processing Ability to customize features quickly Ability to network based on standard protocols

WIN Deployment Criteria & Practice Feature Development Time < 3 months. Feature Customization Time < 1 month. Automated Customer Service and Provisioning Interface. Automated Billing Interface. Automated Network Management Interface. Availability of the associated Self-paced Sales Training Program. Service Roll-out Time < 3 years. Customer Base Penetration > 1.5%.

Advantages of WIN - 1: Reduced delivery time for services. Efficient network utilization. Reduced costs for service deployment. Supports a wide set of service application. Flexibility that makes elements such as fraud control and specialized services more easily deployed.

Advantages of WIN - 2: Helps to get new services to market quickly. Reduced network component costs. Rapid service creation & deployment. Supplies customized management of mobility & Enhanced services

In Conclusion Wireless Intelligent Networking allows the service provider to rapidly introduce new services. Mobile Pre-Pay is a common application. Maintaining and monitoring the Common Channel Signaling (CCS) network is critical to its success. Understanding and troubleshooting the SS7 protocol is a key part of that success.
