context: [TS 24.341, clause 5.3.1.2]: When an SM-over-IP sender wants to submit an SM over IP, the SM-over-IP sender shall send a SIP MESSAGE request with the following information: a) the Request-URI, which shall contain the PSI of the SC of the SM-over-IP sender; NOTE 1: The PSI of the SC can be SIP URI or tel URI based on operator policy. The PSI of the SC can be obtained using one of the following methods in the priority order listed below: 1) provided by the user; 2) if UICC is used, then: - if present in the ISIM, then the PSI of the SC is obtained from the EFPSISMSC in DF_TELECOM of the ISIM as per 3GPP TS 31.103 [18]; - if not present on the ISIM, then the PSI of the SC is obtained from the EFPSISMSC in DF_TELECOM of the USIM as per 3GPP TS 31.102 [19]; or - if neither present on the ISIM nor on the USIM, then the PSI of the SC contains the TS-Service-Centre-Address stored in the EFSMSP in DF_TELECOM as per 3GPP TS 31.102 [19]. If the PSI of the SC is based on the E.164 number from the
description: Public Service Identity (PSI) is a critical network attribute used to identify the Service Centre (SC) in the context of Short Message Service (SMS) over IP. It can be represented as a SIP URI or tel URI, depending on operator policy, and is obtained through various methods such as user provision, UICC-based storage, or default values.
explanation: The text describes PSI as a parameter essential for identifying the Service Centre in SMS over IP communication, aligning with the definition of a parameter as a value used within a system or protocol.
