What is Wireless Intelligent Network (WIN)

Increasing complexity in telecommunications services requires ever more complex standards, and therefore the need for better means to write them. 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. Wireless Intelligent network is developed to drive intelligent network capabilities such as service independence, separation of basic switching functions from service and application functions and independence of applications from lower-level communication details into wireless networks.

Introduction of Wireless Intelligent Network (WIN)

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.

Intelligent network (IN) solutions have revolutionized wire-line networks. Rapid creation and deployment of services has become the hallmark of a wire-line network based on IN concepts. Wireless intelligent network (WIN) will bring those same successful strategies into the wireless networks.

Wireless intelligent network (WIN) is a concept being developed by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. The charter of this committee is to drive intelligent network (IN) capabilities, based on interim standard (IS)-41, into wireless networks. IS-41 is a standard currently being embraced by wireless providers because it facilitates roaming. Basing WIN standards on this protocol enables a graceful evolution to an IN without making current network infrastructure obsolete.

Benefits of Wireless Intelligent Network (WIN)

The main benefit of intelligent networks is the ability to improve existing services and develop new sources of revenue. To meet these objectives, providers require the ability to accomplish the following:

  • Introduce New Services Rapidly: Intelligent network provides the capability to provision new services or modify existing services throughout the network with physical intervention.
  • Provide Service Customization: Service providers require the ability to change the service logic rapidly and efficiently. Customers are also demanding control of their own services to meet their individual needs.
  • Establish Vendor Independence: A major criterion for service providers is that the software must be developed quickly and inexpensively. To accomplish this, suppliers must integrate commercially available software to create the applications required by service providers.
  • Create Open Interfaces: Open interfaces allow service providers to introduce network elements quickly for individualized customer services. AIN technology uses the embedded base of stored program-controlled switching systems and the SS7 network. The AIN technology also allows for the separation of service-specific functions and data from other network resources. This feature reduces the dependency on switching system vendors for software development and delivery schedules. Service providers have more freedom to create and customize services.

Functional Components of Wireless Intelligent Network

Components of Wireless Intelligent Network (WIN)


Figure 1: Components of Wireless Intelligent Network (WIN)

Intelligent Peripheral (IP):  The IP gets information directly from the subscriber, be it credit card information, a PIN, voice activated information. The peripheral gets information, translates it to data, and hands it off to another element in the network-like the SCP-for analysis and control.

MSC – The mobile switching center used for switching function portion of the network.

Signal Transfer Point (STP): This is a packet switch in the signaling network that handles distribution of control signals between different elements in the network such as MSCs and HLRs or MSCs and SCPs. The advantage of an STP is that it concentrates link traffic for the network. It can also provide advanced address capabilities such as global title translation and gateway screening.

Service Control Point (SCP): This device provides a centralized element in the network that controls service delivery to subscribers. High-level services can be moved away from the MSC and controlled at this higher level in the network. It is cost-effective because the MSC becomes more efficient, does not waste cycles processing new services, and simplifies new service development.

MSC as Service Switching Point (SSP):  In the IN, the SSP is the switching function portion of the network. The mobile switching center (MSC) provides this function in the WIN.

Visitor location register (VLR): Within an MSC there is a VLR that maintains the subscriber information for visitor or roamers to that MSC. Every MSC or group of will have a VLR.

Home location register (HLR): Information on roamers is obtained from the subscriber HLR. Each subscriber is associated with a single HLR, which retains the subscriber’s record. When the subscriber roams to another switch, the VLR queries the subscribers home location register to get information about subscribers.

The Wireless Intelligent Network (WIN) intends to take advantage of the Advanced Intelligent Network (AIN) concept and products developed from wire line communication. However, progress of AIN deployment hands been slow due to the many barriers that exist in traditional wire line carriers, multiple vendor expertise and computerized service creation and implementation tools.

Advantages of Wireless Intelligent Network (WIN)

  • Functions can be developed independently
  • Efficient network utilization
  • Mobility management and radio frequencies (Radio Control Function – RCF)
  • Rapid services creation and deployment
  • Deliver high volume data
  • Takes less delivery time for services

Disadvantages of Wireless Intelligent Network (WIN)

  • Implementation cost
  • Lower speed compared to a wired network
  • More complex to configure to wired network
