Abstract— Increasing difficulty in telecommunications services requires ever more difficult standards, and therefore the need for better means to write them. Today's wireless subscribers are much more refined telecommunications users than they were five years ago. Over the years, scenario-driven tactics have been introduced in order to describe functional aspects of systems at several levels of concept. Their application to early stages of design and standardization processes increases new hopes in editing concise, imaginative, maintainable, and reliable documents that need to be understood by a variety of readers. They want multiple services that allow them to handle or select incoming calls in a variety of ways. Wireless Intelligent network is developed to initiate network capabilities such as service independence, switching functions from service and application functions and independence of applications from lower-level communication details into wireless networks. The main weapon for authorizing providers to deliver individual services with enhanced flexibility is Wireless Intelligent Networks (WINs).

I. INTRODUCTION

The Wireless Intelligent Network (WIN) is a network which supports the use of intelligent network skills to provide unified mortal services, personal mobility services, and advanced network services in the mobile environment. (WIN) is a notion being developed by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. The charter of this committee is to effort intelligent network (IN) capabilities, based on provisional standard (IS)-41, into wireless networks. IS-41 is a standard currently being involved by wireless providers because it enables roaming. Basing WIN standards on this protocol enables a elegant development to an IN without making current network structure obsolete. As the wireless market becomes progressively competitive, rapid positioning of enhanced services becomes dangerous to a successful wireless strategy. Improved services are very imperative to wireless customers.

II. WIRELESS INTELLIGENT NETWORK SERVICES

A. HANDS-FREE, VOICE-CONTROLLED SERVICES: Voice control services offer a completely hands-free experience by eliminating the need to press button to activate highly accurate speech recognition command and control features. The system analyses the person’s specific voice and uses it to fine-tune the recognition of that person’s speech. There are two main types of automatic speech recognition (ASR). Specific spoken phrases are required by the speaker-dependent device to uniquely identify an individual user. Each user is required to train the ASR system by recording samples of each specific phrase. The other is speaker-independent ASR, which requires the use of specific spoken phrases that are independent of the speaker. The individual user need not train the system.

B. VOICE-CONTROLLED DIALING (VCD): This service allows the subscriber to place a call using spoken command.VCD may be used during call beginning or during the call itself.

C. VOICE-CONTROLLED FEATURE CONTROL (VCFC): This service allows the authorized user to specify feature operations, which can be carried out via feature-control strings by means of spoken commands. VCFC licenses a calling party to call a special VCFC directory number, recognize the calling party as an authorized subscriber with a mobile directory number and personal identification number (PIN), and specify feature operations via one or more feature-control strings. This service is similar to remote feature control (RFC) except that the subscriber is allowed to dial feature-control digits or instructions using spoken words and idioms instead of keypad digits.

D. VOICE-BASED USER IDENTIFICATION (VUI): This service employs a form of automatic speech recognition to confirm the identity of the chatterer. Access the services can then be delimited to the user whose voice has been used to train the recognition device.

E. INCOMING CALL-RESTRICTION/CONTROL This service allows the user to execute limitations to an incoming call as follows: it may dismiss normally to the subscriber; it may dismiss to the subscriber normal altering; it may terminate to the subscriber with different alerting; it may be promoted to another number; it may be progressed to another voice mail; it may be routed to any specific message; or it may be blocked. These kinds of services help subscribers control incoming calls and their monthly airtime bills.

F. CALLING NAME PRESENTATION (CNAP): This service provides the name identification of the calling party (person name, company name, restricted , not available) as well as the date and time of the call.

G. PASSWORD CALL ACCEPTANCE (PCA): This service allows the subscriber to confine incoming calls only to those callers who can offer legal passwords.

H. SELECTIVE CALL ACCEPTANCE (SCA): This service allows the subscriber to check incoming calls only to those calling parties whose numbers are in the limited list.

I. SHORT MESSAGE SERVICE (SMS): This service allows the short message entities (SMEs) the short message users to receive or send short messages (packet of data).

J. SPEECH-TO-TEXT CONVERSION (STC): This service allows the user to create a short alphanumeric message by means of spoken phases.

K. PREPAID PHONE: This service permits the user to wage before calling ie., not to be billed. This can take a number of forms, for instance a debit card, a linking to a smart card and others.

III. ARCHITECTURE OF WIN

Different wireless networks are stated by different normalization establishments and display different architecture. However, a common framework can be recognized in all wireless systems. Thus some IN elements are used as the basis for an architecture public to all wireless networks. The following are the main components of a wireless system.

A. HANDS-FREE, VOICE-CONTROLLED SERVICES: The MS terminates the radio path on the user side of the network permitting the user to gain contact services from the network. It integrates user interface function, radio function, and control function with the most common equipment applied in the form of a mobile telephone.

B. BASE STATION: The basic station dismisses the radio path on the network side and offers connection to the network. It is composed of two fundamentals: Base Transceiver Station (BTS) Base Station Controller (BSC).

C. MOBILE SWITCHING CENTER (MSC): The MSC provides a programmed switching between users within the same network or other public switched networks, synchronizing calls and routing procedures. In general, an MSC controls several BSCs, but it may also serve in different abilities. The MSC provides the SSP function in a wireless IN.

D. VISITOR LOCATION REGISTER (VLR): The VLR is a database containing provisional records related with subscribers under the status of a caller. A subscriber is considered a caller if such a subscriber is being served by another system within the same home service area or by other system away from the respective home service area. The information within the VLR is saved from the HLR. An VLR is usually co-located with an MSC.

E. HOME LOCATION REGISTER (HLR): The HLR is the primary database for the home subscriber. It maintains information records on subscriber current location, identification, user profile and so on. As HLR may be co-located with an MSC or it may be located independently of the MSC.

F. GATEWAY (GTW): The GTW helps as an interface between the wireless network and the external network.

G. SERVICE CONTROL POINT(SCP): The SCP provides a combined element to control service sending to subscribers. It is responsible for higher level services that are usually carried out by the MSC in wireless networks not using IN facilities.

H. SERVICE TRANSFER POINT (STP): The STP is a packet switch device that handle the spreading of control signals between different elements in the network.

I. INTELLIGENT PERIPHERAL (IP): The IP methods the information of the subscriber (credit card information, personal information, voice –activated information)in support of IN services within a wireless network.

J. EXTERNAL NETWORK: The external network establishes the ISDN (Integrated Services Digital Networks), CSPDN( Circuit-Switched Public Data Network), PSPDN(Packed-Switched Public Data Network)and PSTN(Public-Switched Telephone Network).

IV. ADVANTAGES AND DISADVANTAGES A. ADVANTAGES  Takes less conveyance time for services.  Functions can be established independently.  Efficient network intake.  Network is more stable.  Rapid services manufacture and distribution.  Deliver high volume of data.  Network is more stable.

B. DISADVANTAGES  Implementation cost.  Poorer speed compared to a wired network.  More difficult to configure to wired network.

V. CONCLUSIONS

The conventional service arrangement in the Public Land Mobile Network (PLMN) is known as Wireless Intelligent Networks (WIN). The basis behind Intelligent Networks is splitting service intelligence from the switching and calls control functions of telecommunication networks and unifying it. Specific resource capabilities, such as text-to-speech conversion can also be incorporated for greater efficiency and cost savings. Additionally, by regulating the interfaces for communicating between the elements, one could mix and match elements from numerous network equipment dealers, thus providing elasticity and organization choices to the service providers and carriers. WIN has solved at least the two problems such as opening the networks and multi-standard compatibility.
