METHOD FOR MAINTAINING EMERGENCY OPERATION IN DIGITAL TELECOMMUNICATION TERMINALS

摘要

The allocation of user data channels in a digital telecommunication system is intended to be controlled in such a way that, during the transition to emergency operation, it is highly probable that an existing connection between the connection line and a terminal with emergency power authorisation can be maintained when a direct connection is set up. When user data channels are allocated at an interface to which a terminal with emergency power authorisation is connected and at an interface to which the connection line is connected, an alternate check is carried out to ascertain which seizure condition prevails at the respective other interface. The user data channels are then allocated in such a way that a connection can be set up between the connection line and the interface of the terminal with emergency power authorisation via channels of the same type which can then be maintained in emergency operation. The probability that an existing external connection between a terminal with emergency power authorisation and a connection line can be maintained during the transition to emergency operation is substantially increased due to the channel allocation method.
