1. An apparatus, comprising:
- a transmitter configured to send, during a subscriber equipment terminated call, a session invitation message to a subscriber equipment, the session invitation message comprising authentication information;
a determiner configured to determine whether a verification of the authentication is required;
a processor configured to,if the verification is not required,forward a scheduled result to a network control element by including the scheduled result into the session invitation message, and,if the network control element has to perform the verification,receive the scheduled result from another network control element, wherein the scheduled result is included in the session invitation message,extract the scheduled result from the session invitation message,forward the session invitation message without the scheduled result to the subscriber equipment,verify an authentication result with the scheduled result, andrepeat the verification for a predetermined number of times, wherein different authentication information are used.

13. A method, comprising:
-
sending, during a subscriber equipment terminated call, a session invitation message from a network control element to the subscriber equipment, the session invitation message comprising authentication information; determining, by the network control element, whether the network control element has to perform a verification of the authentication or not; and
,in case the network control element does not have to perform the verification, forwarding a scheduled result to a second network control element by including the scheduled result into the session invitation message, in case the network control element has to perform the verification, receiving the scheduled result from another network control element, wherein the scheduled result is included in the session invitation message, extracting the scheduled result from the session invitation message, forwarding the session invitation message without the scheduled result to the subscriber equipment, and verifying an authentication result with a scheduled result; and repeating the verification for a predetermined number of times, wherein different authentication information are used. - View Dependent Claims (14, 15, 16, 17)

18. A computer program embodied on a computer-readable medium, the computer program comprising computer code for causing a processor to perform operations comprising:
-
sending a session invitation message from a network control element to the subscriber equipment, the session invitation message including authentication information; determining, by the network control element, whether the network control element has to perform a verification of the authentication or not; and
,in case the network control element does not have to perform the verification, forwarding a scheduled result to a second network control element by including the scheduled result into the session invitation message, in case the network control element has to perform the verification, receiving the scheduled result from another network control element, wherein the scheduled result is included in the session invitation message, extracting the scheduled result from the session invitation message and forwarding the session invitation message without the scheduled result to the subscriber equipment, verifying an authentication result with a scheduled result; and repeating the verification for a predetermined number of times, wherein different authentication information are used.

19. An apparatus, comprising:
-
sending means for sending, during a subscriber equipment terminated call, a session invitation message to the subscriber equipment, the session invitation message including authentication information; determining means for determining whether a verification of the authentication is required; and
,transceiver means for forwarding a scheduled result to a second control network by including the scheduled result into the session invitation message, if the verification is not required, wherein if the verification is required, the transceiver means is for receiving the scheduled result from another network control element, wherein the scheduled result is included in the session invitation message, extracting means for extracting the scheduled result from the session invitation message and to forward the session invitation message without the scheduled result to the subscriber equipment, verification means for verifying an authentication result with a scheduled result and repeating means for repeating the verification for a predetermined number of times, wherein different authentication information are used.
