Description

When the MSC requests a cipher from a set of ciphers as stated in the BSSMAP CIPHER MODE REQUEST, we should check if the (bsc-)chosen cipher actually is within that set.

Care must be taken as the 'chosen algorithm' IE is optional.

A corresponding TTCN-3 test case should be developed, trying to COMPLETE with a cipher that's not in the set of those REQUESTed
