A method for generating an emergency call as well as an emergency sensing device and a mobile phone for executing this method. An emergency event is triggered on the emergency sensing device. When detecting the emergency event, the emergency sensing device activates a transmitter and transmits an emergency signal via a wireless communication interface to the mobile phone. The mobile phone establishes an emergency call to a predefined destination, when receiving via the wireless communication interface such emergency signal from the emergency sensing device.

Emergency call method

The present invention relates to a process and also to a service computer, a switching center, terminals, program modules and memory means with program modules for handling incoming telephone calls for a subscriber line (VA) of a telecommunications network (PSTN) during an online data-network session blocking the subscriber line (VA). In this process a terminal (TERA) sets up a connection (VA, VA, VPOP) to an online data-network access device (POP) via the subscriber line (VA). Thereupon the online data-network access device (POP) sends current access data to the terminal (TERA), which the terminal (TERA) signals to a service computer (SCP) of the telecommunications network. If a switching center (SW) of the telecommunications network then detects an incoming call destined for the subscriber line (VA), the switching center (SW) then signals the fact that this call is waiting to the service computer (SCP) which supplies at least one predetermined service for the purpose of processing the incoming call. The service may, for example, consist in a message being sent to the terminal (TERA), in which attention is drawn to the incoming call, or in the incoming call being forwarded to an alternative destination (TELA).

A requesting terminal signals a call request (CALL) to a control unit of a first communications network. The control unit then determines whether sufficient capacity is available in the first communications network to establish the connection requested by the call request. In the event of insufficient capacity, the control unit transmits an overload message (DAT) to the requesting terminal. It only initiates an alternative establishment of the requested connection via another, second communications network after it receives an acknowledge message (ACK) issued by the requesting terminal.
