The security mechanisms which are specified are independent of applications.
The present document describes the functional requirements of the security mechanisms with the implementation detail of these mechanisms being described in the stage 2 specification (TS 23.048).
The present document is the result of a feasibility study carried out on this topic, contained in GSM 11.15.
Within the scope of this document, the UICC refers here to a ICC which support at least one application in order to access a cellular network.
The ICC is considered as a platform, which is either based on TS 31.101 [13], here called "3G platform", or TS 51.011 [23], here called "2G platform". |

23.039 | Interface Protocols for the connection of Short Message Service Centers (SMSCs) to Short Message Entities (SMEs) | TR | 5.0.0 | C1 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.039/23039-500.zip | The present document describes a range of alternative interfaces which may be utilised by Short Message Service Centre (SMSC), and Short Message Entity (SME), developers for the connection of SMEs to SMSCs.
The purpose of the present document is to provide a single document within which the various proprietary SMSC to SME interface standards may be accommodated as optional implementations.
As stated in 3GPP TS 23.040 [1], the functionality of the SMSC is outside of the scope of the 3GPP Technical Specifications. As a result, no standardised interfaces have been specified for the connection of SMEs to the SMSC. In the absence of a prevailing standard, SC (Service Centre), developers have devised their own protocols which have not necessarily been based on any existing standards and are therefore largely incompatible with one another.
This document by referring to the various de-facto protocols will limit the further proliferation of proprietary standards and will benefit new SC/SME developers who may then adopt one or more of the existing protocols outlined in the present document.
This document does not provide recommendations, as to the preferred protocol implementation as all are regarded as being of equal merit. SC/SME implementors should therefore adopt the protocol most suited to their particular implementation, application or market. |

Furthermore, the coding is specified for a set of common application commands within the secured packets. This set is a subset of commands specified in 3GPP TS 51.011 [5] and allows remote management of files on the UICC in conjunction with SMS and the Data Download to UICC feature of 3GPP TS 31.111.
For UICCs based on 3GPP TS 43.019 [15], the set of commands used in the remote applet management is defined in the present document. This is based on the Open Platform card management specification [14]. For UICCs based on other technologies, other loading mechanisms may be used.
The present document is applicable to the exchange of secured packets between an entity in a 3G or GSM PLMN and an entity in the UICC.
Secured Packets contain application messages to which certain mechanisms according to 3GPP TS 22.048 have been applied. Application messages are commands or data exchanged between an application resident in or behind the 3G or GSM PLMN and on the UICC. The Sending/Receiving Entity in the 3G or GSM PLMN and the UICC are responsible for applying the security mechanisms to the application messages and thus turning them into Secured Packets. |

23.127 | Virtual Home Environment (VHE) / Open Service Access (OSA) | TS | 5.2.0 | S2 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.127/23127-520.zip | The present document specifies the stage 2 of the Virtual Home Environment.
Virtual Home Environment (VHE) is defined as a concept for Personal Service Environment (PSE) portability across network boundaries and between terminals. The concept of VHE is such that users are consistently presented with the same personalised features, User Interface customisation and services in whatever network and whatever terminal (within the capabilities of the terminal and the network), wherever the user may be located.
For Release 5, e.g. CAMEL, MExE, OSA and USAT are considered the mechanisms supporting the VHE concept.
Stage 2 specifications for CAMEL, MExE and USAT are addressed in other documents [1], [2], [3]. However, there is no separate stage 2 specification document for OSA. Therefore, the present document addresses stage 2 aspects for OSA. |

UESBI may be used by correcting mechanisms to overcome some of the issues that have been recognized by 3GPP in TR 25.994 (Measures employed by the UMTS Radio Access Network (UTRAN) to overcome early User Equipment (UE) implementation faults) [13], and other such documents. The description of these correcting mechanisms is out of the scope of this TS.
ITU-T Recommendation I.130 [1] describes a three-stage method for characterisation of telecommunication services, and ITU-T Recommendation Q.65 [2] defines stage 2 of the method. |
