Method and system for handling a network-identified emergency session
First Claim
1. An apparatus, comprising:
- a receiver configured to receive a message from a user equipment to initiate a session, said message indicating an identifier of a called entity;
an analyzer configured to analyze the identifier and to detect a request for an initiation of an emergency session; and
a sender configured to send information to the user equipment that the session to be initiated is an emergency session,configured toinform an emergency center or another apparatus that an emergency session is to be established when the session to be initiated is an emergency session, andto send the information to the user equipment or another apparatus only after receipt of a response from the emergency center.

Abstract
The invention relates to a method and system for establishing an emergency session in a communication system which includes at least one user equipment and one or more network entities involved in establishing an emergency session. When the user equipment initiates a session by sending a message to a network entity indicating an identifier, e.g. the call number or logical name of a called entity, one of said network entities analyses the received identifier. When detecting that the session to be initiated is an emergency session, an information is returned to the user equipment for informing the latter that the initiated session is an emergency session. The user equipment thereupon initiates the execution of an emergency session. Thus, even when the user equipment is unable to detect, by itself, that the intended session is an emergency session, the network will inform the user equipment on the emergency session for ensuring appropriate handling thereof.
