Emergency communication in IMS network: Challenges in implementation

Emergency communication is an important part of communication for the telecoms not only due to regulation but primary due to their responsibilities to the customers and the role they have in society. This paper describes the challenges which we are facing when implementing emergency communication in IMS network regarding the architecture and special requirements demanded by the Regulator and emergency service centers. In focus are: the architecture for customers accessing the service over fixed access and the possible implementations for customers that are accessing the service over LTE (Long Term Evolution) network.
