Introduction
Location based service is used to locate the subscribers location. This identified location could be used for providing various location-based services. These could vary from tracking a fleet of vehicles by transporters to doing promotions based on location of subscriber. It is also a very useful utility service for the corporate which want to keep track of their people in the field. An important distinction between location based services and other services is that this network based solution is independent of both handset and Subscriber Identity Modules (SIMs). Users are not required to have the newest phone with enhanced features or a specific brand of phone. It is only the operator who will keep track of the location of a subscriber. This service may require the acceptance of B-Party whose location is to be disclosed based on how the service is implemented. Wireless service providers can generate revenue from service management, using a wealth of existing subscriber data.
