Description / Abstract:

FOREWORD

This document contains the requirements for the Removable User Identity Module (R-UIM). It is an extension of Subscriber Identity Module (SIM), per latest [17]1 capabilities, to enable operation in a [14/15] radiotelephone environment. Examples of this environment include, but are not limited to, analog, [14]-based CDMA and the [1-5] family of standards.

These requirements are expressed as additions to the current specification of the SIM. The composite R-UIM is comprised of the current SIM specification and this ancillary or "delta" document. The SIM specification is included as a reference. It is intended that all upgrades to the SIM specification will also apply to the R-UIM.

The current SIM specifications (see references) address the physical and electrical characteristics of the removable module, along with the user-to-card interface and terminal-to-card signaling protocol. Operation in a [14/15] environment requires that additional commands and responses be developed within the context of this document. This document also defines new Elementary Files (EFs) for storage of parameters that are added for operation in a [14/15] environment.

This standard specifies security-related procedures and commands, along with data and information storage items that permit basic operation in the [14/15] environment. Later versions are expected to also address the delivery of [14/15] user features and services via the R-UIM.

Although the focus of this document is compatibility with [14/15], the scope of this document may later be expanded to include compatibility with other [15]-related technologies such as TDMA and AMPS.
