1. Initial Attach - Part 1 (en)

The Initial Attach document discusses procedures for initial attach by a user attaching to an LTE network for the first time, as defined as EMM Case No. 1 in our previous document, “Eleven EMM Cases in an EMM Scenario”. The document consists of two companion documents: this document (Part 1. Cases of Initial Attach) and the subsequent document (Part 2. Call Flow of Initial Attach). In this document, we will distinguish different cases of initial attach (Attach Case 1 ~ Attach Case 5), and different function blocks involved in each case. Then we will explain different procedures required in each case of initial attach. In the subsequent document, detailed initial attach procedures in Attach Case 1 will be described.
