context: At Idle mode mobility, can signal its UTRAN KH capability indication to the CNN(*) in RAU/LAU request messages. And CNN+ can indicate its UTRAN KH capability to the in RAU /LAU Accept messages. During the SMC procedure, if needed, the CNN(*) can indicate their UTRAN KH capability to the , just the same as in the initial attach procedure. At SRNS relocation, the source RNC+ should send UE UTRAN KH capability to the target RNC(*) in source RNC to target RNC transparent container IE. However, the current specs do not seem to guarantee that a legacy source RNC includes an IE that it doesnât understand to the target RNC(*). In this case should signal its UTRAN KH capability to the target RNC(*) in the first UL message (i.e., UTRAN Mobility Information Confirm/Physical Channel Reconfiguration Complete/Cell Update Confirm/URA Update Confirm) to the target one. While the target RNC+ can indicate its UTRAN KH capability to in the first DL message (i.e., Physical Channel Reconfiguration/UTRAN
description: The UMTS Terrestrial Radio Access Network (UTRAN) provides radio access to mobile devices within the Universal Mobile Telecommunications System (UMTS). It comprises Node Bs and Radio Network Controllers (RNCs), which manage the air interface and connect to the core network.
explanation: The text describes UTRAN as a component of UMTS responsible for managing the air interface and connecting mobile devices to the core network. This functionality directly relates to the definition of a Network entity type.
