FIELD: physics; communications. ^ SUBSTANCE: invention relates to communication engineering and specifically to establishing emergency communication sessions, for example emergency calls in IP networks. Proposed are a method and a system for establishing an emergency communication session in a communication system, which contains at least one unit of user equipment and one or more network objects participating in establishing an emergency communication session. When user equipment initiates session establishment by sending a message to a network object, in which an identifier is indicated, for example a call number or logical name of the called object, one of the network objects analyses the received identifier. Upon detection that the initiated session is an emergency communication session, information is returned to the user equipment to inform the latter that, the initiated session is an emergency communication session. After that user equipment initiates establishment of an emergency communication session. That way, even if the user equipment cannot detect on its own whether the given session is an emergency communication session, the network will inform the user equipment on the emergency communication session so as to enable its corresponding processing. ^ EFFECT: more reliable establishment of emergency communication session. ^ 29 cl, 4 dwg |
