0  IntroductionWord‑p. 4

The present document is the result of a split of TS 23.048 Release 5 between the generic part and the bearers specific application. The generic part has been transferred to SCP. The present document is the bearers specific part.

1  ScopeWord‑p. 5

The present document specifies the structure of the Secured Packets in implementations using Short Message Service Point to Point (SMS-PP), Short Message Service Cell Broadcast (SMS-CB), Unstructured Supplementary Service Data (USSD) and and Hyper Text Transfer Protocol (HTTP) based on ETSI TS 102 225 [9].
The structure of the Secured Packets shall comply with the one defined in ETSI TS 102 225 [9]. The present document only contains additional requirements or explicit limitations for SIM/USIM applications.
It is applicable to the exchange of secured packets between an entity in a PLMN and an entity in the (U)SIM.
Secured Packets contain application messages to which certain mechanisms according to ETSI TS 102 224 [2] have been applied. Application messages are commands or data exchanged between an application resident in or behind the PLMN and on the (U)SIM. The Sending/Receiving Entity in the PLMN and the UICC are responsible for applying the security mechanisms to the application messages and thus turning them into Secured Packets.
