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.

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.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

• References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
• For a specific reference, subsequent revisions do not apply.
• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
