DS TS 131 111 V14.5.0:2018

Digital cellular telecommunications system (Phase 2+) (GSM); Universal Mobile Telecommunications System (UMTS); LTE; Universal Subscriber Identity Module (USIM) Application Toolkit (USAT) (3GPP TS 31.111 version 14.5.0 Release 14)

Scope

The present document defines the interface between the UICC and the Mobile Equipment (ME), and mandatory ME
procedures, specifically for "USIM Application Toolkit".
The present document refers in its majority to the ETSI TS 102 223 [32], which describes the generic aspects of
application toolkits within the UICC.
USAT is a set of commands and procedures for use during the network operation phase of 3G/LTE, in addition to those
defined in TS 31.101 [13].
Specifying the interface is to ensure interoperability between a UICC and an ME independently of the respective
manufacturers and operators.
The present document defines for 3G/LTE technology:
- the commands;
- the application protocol;
- the mandatory requirements on the UICC and ME for each procedure.
The present document does not specify any aspects related to the administrative management phase. Any internal
technical realization of either the UICC or the ME are only specified where these reflect over the interface. The present
document does not specify any of the security algorithms which may be used.
For the avoidance of doubt, references to clauses of ETSI TS 102 223 [32] include all the subclauses of that clause,
unless specifically mentioned.
The target specification ETSI TS 102 223 [32] contains material that is outside of the scope of 3GPP requirements and
the present document indicates which parts are in the scope and which are not.
A 3GPP ME may support functionality that is not required by 3GPP, but the requirements to do so are outside of the
scope of 3GPP.
