OVERVIEW 1. Wireless intelligent network (WIN) is a concept being developed by the Telecommunications Industry Association (TIA) Standards Committee TR45.2. 2. The wireless intelligent network (WIN) paradigm is the key to helping service providers offer new enhanced services at fair rate. 3. Examples of services offered by WIN are incoming call screening, calling name presentation, short message services, voice controlled dialing, speech to text conversion etc.

CHARACTERISTICS 1. It allows for rapid introduction of new services 2. It is customer and telephone provider programmable 3. It is supplier transparent and independent 4. It supports enhanced service provider access

SERVICES 1. Hands-Free, Voice-Controlled Services 2. Voice-Controlled Dialing (VCD) 3. Voice-Controlled Feature Control (VCFC) 4. Voice-Based User Identification (VUI) 5. Incoming Call-Restriction/Control 6. Calling Name Presentation (CNAP)

7. Password Call Acceptance (PCA) 8. Selective Call Acceptance (SCA) 9. Short Message Service (SMS) 10. Speech-to-Text Conversion (STC) 11. Billing, Prepaid Cellular

FUNCTIONAL COMPONENTS

2. service control point (SCP) 1. 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. 2. service control point (SCP) This device provides a centralized element in the network that controls service delivery to subscribers

4. signal transfer point (STP) 3. intelligent peripheral (IP) The IP gets information directly from the subscriber, be it credit-card information, a PIN, or voice-activated information. 4. 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.

5. location registers These are used to supplement MSCs with information about the subscriber. The following location registers help to get around that problem: Visitor location register (VLR) Home location register (HLR) 6. WIN call model The WIN call model enables the network to handle new triggers and new transaction capability application part (TCAP) messages.

PRINCIPLES OF INTELLIGENT NETWORKING

EVOLUTION TO WIN The following steps will need to occur before WIN will be a reality: 1. Incorporation of SCP, IP, and SN into the wireless network architecture 2. Evolution of the MSC to a SSP 3. Separation of call control and transport from service control 4. Development of generic call models, events, and trigger points

ADVANTAGES OF WIN 1. Network setups can be done without fixed infrastructure. 2. Takes less delivery time for services. 3. Network is more stable. 4. Deliver high volume of data.

DISADVANTAGES OF WIN 1. Implementation cost 2. Less secure 3. More complex to configure 4. Easily affected by surroundings 5. Lower speed

CHALLENGES OF WIN 1. Energy efficiency 2. Scalability 3. Heterogeneity 4. Privacy and security 5. Power management 6. Real-time

CONCLUSION 1. Wireless Intelligent Networking allows the service provider to rapidly introduce new services 2. Mobile Pre-Pay is a common application 3. The first phase of WIN standards was published in 1999 and established the fundamental call models and operations required to support this flexible service architecture.
