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.

Abstract: In a communication system providing a group communication service and advertisement of an existing and newly created group, information on usable media types in the group is sent to group members in a message advertising the group.

Abstract: A resource list or a user profile is provided with a new parameter, called a group advertisement parameter, which indicates whether a user allows a group advertisement for an individual communication group or not. The user can set the group advertisement parameter in a resource list when he/she creates the communication group. When the user has created a communication group, a group communication server processes the group further as any other group. If the group communication server observes that a group advertisement parameter is present or set active, the server starts advertising the communication group to all group members or to a selected subset of group members.
