Section 2.1 described the basic network architectures from the GSM to the LTE system. In this section, we will introduce further the evolutions of the mobile communications networks and systems, from the GSM to LTE, with respect to their air interface and network architectures. The 3GPP, which is described later in Section 2.5, is responsible for standardizing and defining the system architecture evolutions (SAEs) of the GSM to the 5G system‐based mobile communications networks.
