Systems, methods, and apparatuses for diameter based interfaces to enable restrictions of coverage enhancement in wireless networks

A non-transitory computer-readable storage medium having computer-readable instructions stored thereon, the computer-readable instructions to, when executed, instruct a processor of a first network node to:

• process an enhanced coverage request from an application function;
• in response to the enhanced coverage request, encode a configuration information request (CIR) command for a second network node, the CIR command comprising a query for current settings of an enhanced-coverage-restriction attribute-value pair (AVP) corresponding to a user equipment (UE);
• process a configuration information answer (CIA) command from the second network node, the CIA command comprising an enhanced-coverage-restriction-data AVP comprising the current settings of the enhanced-coverage-restriction-attribute AVP for the UE;
• and
• generate an enhanced coverage response for the application function to indicate, based on the current settings, whether the UE is restricted from operation in an enhanced coverage mode.

An apparatus for a home subscriber server (HSS), the apparatus comprising:

• a first interface to receive, from a service capability exposure function (SCEF), a configuration information request (CIR) command comprising a query for a current setting of an enhanced coverage restriction corresponding to a user equipment (UE);
• and
• a processor to encode a configuration information answer (CIA) command to provide to the SCEF through the first interface, the CIA command comprising enhanced coverage restriction data including the current setting of the enhanced coverage restriction corresponding to the UE,
• wherein the first interface comprises a diameter based S6t interface, and
• wherein the CIR command comprises an enhanced-coverage-restriction attribute-value pair (AVP).
