An emergency call service system in an Internet Protocol (IP) network and a method thereof are provided. The system includes a policy control server, an emergency call agent, a call agent, and a network manager. The policy control server generates position information of a user terminal by mapping an IP address and local information to an identification (ID) of the user terminal. The emergency call agent detects a suitable emergency center for the user terminal sending an emergency call, and makes an emergency-call connection between the user terminal and the emergency center. The call agent relays the emergency call of the user terminal to the emergency call agent. The network manager stores position information of the user terminal generated through the policy control server, provides the emergency call agent with the position information of the user terminal sending the emergency call, and performs a resource reservation for the emergency-call connection.
