context: Figure 54: MBMS CN De-Registration procedure. Successful operation. The CN initiates the procedure by sending a MBMS CN DE-REGISTRATION REQUEST message. The MBMS CN DE-REGISTRATION REQUEST message shall contain the following IEs: - TMGI; - Global CN-ID IE, only when the MBMS CN DE-REGISTRATION REQUEST message is sent from a CN node towards an RNC for which the sending CN node is not the default CN node. If the Global CN-ID IE is not included, the MBMS CN DE-REGISTRATION REQUEST message shall be considered as coming from the default CN node. Upon reception of the MBMS CN DE-REGISTRATION REQUEST message, the RNC shall remove all associated MBMS context(s) and resources corresponding to the MBMS Bearer Service identified by the indicated TMGI and shall report it to the CN by sending the MBMS CN DE-REGISTRATION RESPONSE message. Upon reception of the MBMS CN DE-REGISTRATION REQUEST message, if no existing MBMS Bearer Service can be identified by the indicated TMGI in the RNC, it shall
description: The Core Network (CN) is a key component of the telecommunications infrastructure, responsible for managing and controlling various network functions. In the context of MBMS CN De-Registration procedure, the CN initiates the process by sending a request message to the RNC, which then removes associated MBMS contexts and resources. The CN plays a crucial role in coordinating and managing the de-registration process.
explanation: The abbreviation 'CN' is classified as a Network Function based on its role in initiating and controlling the MBMS CN De-Registration procedure, as described in the context. The CN's responsibility for sending request messages, managing MBMS contexts, and resources highlights its functionality as a network component.
