Abstract

A fifth-generation (5G) Core Access and Mobility Management Function (AMF) (5GC AMF) is configured to decode a REGISTRATION REQUEST message received from a user equipment (UE). When the UE indicates support for restriction on use of enhanced coverage (EC), a RestrictEC bit is set to "Restriction on use of enhanced coverage supported" in a 5G mobility management (5GMM) capability information element (IE) of the REGISTRATION REQUEST message. The 5GC AMF may also encode a REGISTRATION ACCEPT message for transmission to the UE. When the UE indicated support for the restriction on use of EC in the REGISTRATION REQUEST message, the 5GC AMF may set the RestrictEC bit in a 5GS network feature support IE in the REGISTRATION ACCEPT message to indicate coverage enhancement modes are restricted.
