Today commercial mobile networks are moving towards 4G networks which is based on Long Term Evolution (LTE) technology standard. LTE is based on Internet Protocol (IP) infrastructures and offers a wide range of broadband features. Currently in the 3G Cellular networks various priority services exist to handle the National Security threat created by natural and man-made events. As the networks evolve to the Next Generation Networks (NGN) one can expect that the same priority services (PS) are also supported in LTE networks.
During emergencies, the public networks can become overloaded due to a mass calling event or network failures. National Security (NS) and Emergency Preparedness (EP) personnel involved in emergency situation may have problems with network access. Enhanced Multimedia Priority Service (MPS) provides a mechanisms in the access and core networks to facilitate the needed priority communications.
This study addresses the NS/EP priority mechanisms in LTE that facilitates the high probability of call completion. These NS/EP priority mechanisms provide capabilities to NS/EP users for voice and data communications. The analysis is twofold. First, it studies the end to end call priority solution provided by telecom vendors on 3G network. Second it analyzes 3GPP standards NS/EP voice priority mechanisms for NGN networks. Finally it presents a potential solution to support the LTE priority mechanism on the Circuit Switch fallback (CSFB) to 1XRTT, limitations of the solution and further research areas with LTE access.
