Name	Type	Description
DeviceApp	simple module	This module models the Device App entity as defined by the ETSI Multi-access Edge Computing (MEC) specifications. The Device App can be instantiated on a User Equipment (UE) that wants to dynamically instantiate a MEC application within a MEC system. It establishes a TCP connection with the User App Lifecycle Management Proxy (UALCMP) entity (see the UALCMP module) and, upon receiving a MEC application instantiation request from another UE application, it sends a message to the UALCMP including the URI of the MEC application to be instantiated. Once the confirmation of successful instantiation is received, the Device App sends an acknowledgment to the UE application that requested it. Moreover, this module is responsible for requesting the deletion of the MEC application from the MEC system upon explicit request from the UE application.
