Introduction

This module provides a discussion of emerging applications in intelligent networks for mobile communications. Mobile IN capabilities are becoming increasing important as mobile network operators strive to deploy advanced value-added services to their customers.

Mobile IN Applications

• Calling Name Presentation: The ability to provide the name of the calling party to the called party, allowing the called party to decide how to handle the call (e.g. the subscriber decides either to answer the call or let it go to voice mail).  WIN/CAMEL is used to query a database that contains name information, which allows for a network-based service rather than programming the GSM phone to recognize caller names.

• Prepay and Account Spending Limit (ASL): Prepay and ASL utilize WIN/CAMEL to allow for metering usage on a prepaid basis and post-paid basis respectively.  ASL has applications for those markets that are not debit based or credit challenge but rather want to just manage usage.  Markets include parental controls and corporate resource management.

• Incoming Call Management (ICM): WIN/CAMEL is leveraged to manage call termination attempts to customize subscriber’s inbound calling experience.  The subscriber can decide how inbound calls will be automatically managed.  Features include automatic call handling (example: route all calls except boss to voice mail for the next hour) fixed-to-mobile convergence capabilities such as routing to mobile when a fixed network number is called.

• Virtual Private Network (VPN): WIN/CAMEL enables a mobile VPN that replicates PBX-like dialing in a mobile environment.  For example, this (typically) group-based feature allows one to hit the digits “2706” and then SEND to actually place a call to 555-123-2706.

• Call Redirect Services (CRS): WIN/CAMEL is utilized to provide a variety of CRS services including redirecting international roamers to their own customer care when they dial call “611”

• Location-based Services (LBS): WIN/CAMEL has been used in the United States to support FCC mandates for wireless emergency calling (e.g. dialing 9-1-1) from a mobile phone.  WIN/CAMEL thus allows for call control, information to be passed to databases, call assistance for routing to a Public Safety Answer Point, and for query of LBS infrastructure such as the Gateway Mobile Location Center (GMLC) for more precise positioning data based on A-GPS or TDOA.  Commercial (non-regulatory) LBS applications are emerging that will rely on WIN/CAMEL include directory services and location-based search and information.
