Abstract
The invention concerns a method for controlling the setting-up of a communication connection by a communication network (TELENET), as well as a service unit for implementing the method. During the call set-up a service request message (SR) for requesting an IN service is transmitted to a network server (SCP to SCP ) if the communication connection that is to be set up fulfils predetermined trigger conditions. The service request message (SR) transmitted to the network server (SCP to SCP ) is classified by a service unit (SSP; LLIN) as essential or non-essential. The operability of the network server is monitored by the service unit (SSP; LLIN). If the service unit (SSP; LLIN) determines that the operability of the network server (SCP to SCP ) is impaired, it initiates the further call set-up of the communication connections if it has classified the service request message (SR) as non-essential and initiates the termination of the further call set-up of the communication connections if it has classified the service request message (SR) as essential.
