Full Description
The present document defines the interface between the Subscriber Identity Module (SIM) and the Mobile Equipment (ME), and mandatory ME procedures, specifically for "SIM Application Toolkit".
SIM Application Toolkit is a set of commands and procedures for use during the network operation phase of GSM, in addition to those defined in TS 11.11 [20].
Specifying the interface is to ensure interoperability between a SIM and an ME independently of the respective manufacturers and operators. The concept of a split of the Mobile Station (MS) into these elements as well as the distinction between the GSM network operation phase, which is also called GSM operations, and the administrative management phase are described in TS 02.17 [3].
The present document defines:the commands;the application protocol;the mandatory requirements on the SIM and ME for each procedure.Unless otherwise stated, references to GSM also apply to DCS 1800.
The present document does not specify any aspects related to the administrative management phase. Any internal technical realization of either the SIM or the ME are only specified where these reflect over the interface. This standard does not specify any of the security algorithms which may be used.
The present document defines an enhancement for GSM Phase 2+ of the SIM/ME interface for GSM Phase 2. While all attempts have been made to maintain phase compatibility, any issues that specifically relate to Phase 1 should be referenced from within the relevant Phase 1 specification.
