Introduction

The Removable-User Identity Module (R-UIM) is an entity that stores and manages the identity of the subscriber and related subscription data, as well as, personal data. In GSM the R-UIM is referred to as the Subscriber Identity Module (SIM). The R-UIM is an extension of GSM SIM capabilities to enable operation in a TIA/EIA-136 and TIA/EIA-41 environment and may also facilitate roaming between GSM and TIA/EIA-136 networks. The R-UIM may be physically removed from one Mobile Equipment (ME) and inserted into another as long as both have compatible R-UIM/ME interfaces.

The network service provider may update the data stored in the R-UIM. This data may be updated via over-the air teleservices and parameter administration techniques or via external programming devices.

R-UIMs may be supported on non TIA/EIA-41 based mobile stations and thus permit a TIA/EIA-41 based subscriber to access service on a non TIA/EIA-41 network if compatible interfaces exist.
