Wireless Intellegent Network

Introduction

The intelligent network (IN) is an architectural concept that enables the real time execution of network services and customer applications in a distributed environment consisting of interconnected computers and switching systems. Beginning in the early 1980’s, the IN was applied to the development of new services in wireline telephone networks. Notable successes were achieved in the United States long distance telephone industry and virtual private network (VPN) services contributed strongly to growth in traffic and revenue.

As we know that the wireless market is becoming increasingly competitive, rapid development of enhanced services become critical to a successful wireless strategy. Rapid creation and deployment of services has become the hallmark of a wireline network based on IN concepts. The WIN will bring those same successful strategies into the wireless networks.

Data-Service Capabilities

Handset displays allow customers to use various massaging services. One, called short message service (SMS), works much like a pager. It allows phones to send and receive messages in addition to making or taking telephone calls. SMS require many SS7 messages just to set up the signaling and the mechanism to get the data through the wireless network. It requires a significant amount of checks and balances, finding the database, pulling up the message, encapsulating it with the right header information to route it to the correct user, and finally sending it out like a phone call.

Calling Name Presentation

CNP displays the name of the calling party on the called party’s terminal. When a call comes in for a wireless subscriber, the subscriber’s home MSC receives the call. The home MSC queries the HLR to determine where the mobile is located. The HLR sends a route request to the MSC serving the subscriber and receives from the serving MSC a temporary local directory number (TLDN), which is routed back to the home MSC. The home MSC uses the TDLN to route the call over the public switched telephone (PSTN) to the serving MSC. When the call is delivered to the serving MSC, the caller’s number is also delivered.

Abstract

Wireless Intelligent Network (WIN) is a concept being developed by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. The motive of WIN is to drive intelligent network (IN) capabilities, based on interim standard (IS)-41, into 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 platforms of the network. . 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 phones, they are becoming more mobile and require more services. Expectations for services have gone beyond the need for emergency assistance; people require the same functionality that they are using on their landline phones.

Win Services

Enhanced services are increasing in popularity. At this point, various carriers within different serving areas are implementing them using available IN protocols and concepts.

 Voice Controlled Services

        Hand free services are the most sought after services today. They need features like voice activated dialing and feature activation which requires special technology that converts voice into data.

Conclusion

        The movement to develop a WIN strategy was originally triggered by wireless network operators under the auspices of the Cellular Telecommunications Industry Association (CTIA). They developed a set of requirements calling for industry standards that defined new network architecture incorporating the service flexibility of INs with the mobility aspects of wireless networks.
