TIA TIA/EIA/IS-808

This standard defines the enhancements required for the support of a mobile station equipped with a User Identity Module (UIM). The UIM provides functionality to certain types of mobile stations to enable them to operate in the wireless network.

This document defines requirements for the wireless network to support operation of UIM equipped mobile stations. A UIM provides compatible mobile stations with the parameters required of mobile stations operating in the TIA/EIA-41 environment and specific additional functionality unique to UIM-equipped mobile stations.

The UIM can be in one of two forms, as either integrated within the mobile station or removable permitting the UIM to be inserted or removed from the mobile equipment. This document addresses Removable UIM (R-UIM) only.
