name: TMGI
full_form: Temporary Mobile Group Identity
context: According to TS 23.003 [4] and TS 38.331 [5], TMGI is defined as Temporary Mobile Group Identity. Temporary Mobile Group Identity (TMGI) is used within MBMS to uniquely identify Multicast and Broadcast bearer services. The TMGI is composed of MBMS Service ID, Mobile Country Code (MCC), and Mobile Network Code (MNC). TMGI is used by the Core Network (CN) of MBS UEs and by MBS UEs as a temporary identity for monitoring of the Paging channel for CN paging if configured by upper layers for MBS multicast reception (e.g., see clause 7.2.5.2 of TS 23.247 [6]). TMGI is a temporary identity. However, since it is being utilized for MBS group paging and its value reused for paging different UEs, as well as being transmitted in cleartext, the privacy attack and DoS attack may be possible.
description: Temporary Mobile Group Identity (TMGI) is a parameter used within MBMS to uniquely identify Multicast and Broadcast bearer services. It is composed of MBMS Service ID, Mobile Country Code (MCC), and Mobile Network Code (MNC). TMGI serves as a temporary identity for monitoring the Paging channel for Core Network paging.
explanation: The context explicitly states that TMGI is used to uniquely identify Multicast and Broadcast bearer services, indicating its role as an identifier or attribute within the network. This aligns with the definition of a Parameter in the provided categories.
