The method includes generating an ATTACH REQUEST using the UE. The ATTACH REQUEST has an attach type. The method includes retrieving the attach type of the ATTACH REQUEST using the NAS layer of the UE, and generating an RRC CONNECTION REQUEST. The RRC CONNECTION REQUEST includes an RRC establishment cause based upon the attach type of the attach request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for determining establishment causes for emergency sessions","description":"A method for initiating a Packet Switched emergency call using a user equipment (UE) is presented.
