IEI is a Information Element Identifier, which is a part of TLV-coded (Type-Length-Value) Information Elements (IEs). In other words, IEI represents type (T) of the data payload which follows it. TLV is an encoding used in most of the classical GSM protocols. I don't recall where it is described in the Standard, but here is a nice paper which you easily find on Google which describes ciphering and described TLV structure as well (section 6.1.2): http://www.cs.ru.nl/~fabianbr/scriptie.pdf -- Regards, Alexander Chemeris.
