Full Description
ETSI TS 131 115 specifies the structure of the Secured Packets in implementations using Short Message ServicePoint 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 documentonly contains additional requirements or explicit limitations for SIM/USIM applications.
It is applicable to the exchange of secured packets between an entity in a 3G or GSM PLMN and an entity in the(U)SIM.
Secured Packets contain application messages to which certain mechanisms according to ETSI TS 102 224 [2] havebeen applied. Application messages are commands or data exchanged between an application resident in or behind the3G or GSM PLMN and on the (U)SIM. The Sending/Receiving Entity in the 3G or GSM PLMN and the UICC areresponsible for applying the security mechanisms to the application messages and thus turning them into SecuredPackets.
