full_form: Short Message Service
context: Clause 7.2 illustrates the LI for SMS over NAS and SMS over IP, depending on the UE capability. A UE capable of receiving SMS over IP may still receive the SMS over NAS depending on its connectivity at the time the message transfer is attempted. In the illustrations, SMS over NAS refers to the SMS over 5GS NAS (where the SMSF that serves the UE is involved). The other possible network topology considerations (e.g. SMS over 4G NAS) are outside the scope of these illustrations even though the principles of LI are the same as for SMS over 5GS NAS. For SMS over IP, the IR-POI in the S-CSCF provides the LI functions as a default method and the IRI-POI in the P-CSCF provides the LI functions as an alternate method (TS 33.127 [3]). In the HPLMN, the IRI-POI in the S-CSCF provides the LI functions as a default method and the IRI-POI in the P-CSCF (with home-routed) or the IBCF (with LBO) provides the LI functions as an alternate method (TS 33.127 [3]). In the VPLMN with LBO, the IRI-POI in the
description: Short Message Service (SMS) is a telecommunications service that enables users to send and receive short messages, typically up to 160 characters. It operates over various network protocols, including NAS and IP, and involves specific network functions for message transfer and law enforcement intercept (LI).
explanation: The context explicitly mentions SMS as a service that can be delivered over different networks (5GS NAS, 4G NAS) and highlights its interaction with other network components like the SMSF, S-CSCF, P-CSCF, and IBCF for LI functions. This indicates that SMS is primarily a telecommunications offering or service.
