Abstract: Provided are a key derivation method and device. The method includes: acquiring a slice identifier corresponding to a network slice to which a user equipment is currently attached, where the slice identifier uniquely identifies the network slice; and transmitting the slice identifier to a designated communication device. The slice identifier is configured to instruct the designated communication device to derive, according to the slice identifier, an intermediate key required by the network slice. By means of the technical solution described above, the problem in the related art that a slice function cannot be implemented normally due to the fact that different network slices probably use the same intermediate key may be solved, and different network slices may correspond to different intermediate keys, thereby avoiding a case that the slicing function cannot be implemented normally caused by allocating the same intermediate key to different network slices.

If the match is successful, an operation indicated by said request message is performed on the successfully matched registration binding relationship. Based on the solution proposed in the present invention, the logic of the registration service can be ensured to be normal.

Abstract: A late call forwarding method in the IMS centralized service. During a call setting up, an ICCF receives a call request from the CSCF serving the called user, called session A, and the ICCF acquires a called user's roaming number and initiates a call to the called user. After receiving the call request, the VMSC serving the called user triggers the late call forwarding service according its determination. A CAMEL service is triggered when the VMSC initiates a call to the forwarding target. The VMSC exchanges messages with the ICCF and informs the ICCE about session associated information and the forwarding reason. When the ICCF determines that the forwarding is needed, it sends a response to the session A does not send the response message, after a telecom application server (TAS) receives the indication, the TAS initiates a regular forwarding service.
