Service unit using essential and non-essential service request message classifications
First Claim
1. A method for controlling the setting-up of a communication connection by a communication network (TELENET), wherein during the call set-up a service request message (SR) for requesting a service is sent to a network server (SCP1 to SCP3) if the communication connection that is to be set up fulfils predetermined trigger conditions, said method including the steps of:
- classifying the service request message (SR) sent to the network server (SCP1 to SCP3) by a service unit (SSP;
LLIN) as essential or non-essential, monitoring that the operability of the network server by the service unit (SSP;
LLIN), and if the service unit (SSP;
LLIN) determines that the operability of the network server (SCP1 to SCP3) is impaired, initiating the further call set-up of the communication connections if it has classified the service request message (SR) as non-essential, and initiating the termination of the further call set-up of the communication connections if it has classified the service request message (SR) as essential.

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 (SCP1 to SCP3) if the communication connection that is to be set up fulfils predetermined trigger conditions. The service request message (SR) transmitted to the network server (SCP1 to SCP3) 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 (SCP1 to SCP3) 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.

7. A service unit (SSP;
- LLIN) for controlling the setting-up of communication connections by a communication network (TELENET), wherein the service unit (SSP;
LLIN) is provided with a communications unit (INT) for communication with at least one IN server (SCP1 to SCP3) and is provided with a control unit (CONTR;
CONTR′
) that is configured so that, during the call set-up of communication connections, it initiates the transmission of at least one service request message (SR) for requesting an IN service to at least one network server (SCP1 to SCP3) if the respective communication connection that is to be set up fulfils predetermined trigger conditions, said control unit (CONTR;
CONTR′
) further characterized in that it;classifies the service request messages (SR) transmitted to the at least one network server (SCP1 to SCP3) as essential or non-essential, monitors the operability of the at least one network server, and if it determines that the operability of one of the network servers (SCP1 to SCP3) is impaired, initiates the further call set-up of those communication connections for which a service request message classified as non-essential has been transmitted to this network server, and the service requested by this service request message has not yet been provided, and initiates the termination of the further call set-up of those communication connections for which a service request message classified as essential has been transmitted to this network server and the service requested by this service request message has not yet been provided. - View Dependent Claims (8, 9)
