Abstract
An apparatus and method for supporting an Assisted Global Positioning System (AGPS) during emergency service in a communication system are provided. The system includes a client, an integration location server, and a dual mode Mobile Station (MS). The client requests MS location information for emergency service. The integration location server receives MS access information and sends a location information request. The dual mode MS receives the location request, activates a second communication modem, and performs an AGPS operation with the integration location server.
