1. An apparatus for a Mobility Management Entity (MME) in wireless network, the apparatus comprising:
processor circuitry that is configured to perform operations comprising:
identifying, from a mobility management (MM) context corresponding to a user equipment (UE) that is capable of operating in coverage enhancement (CE) mode B, a usage setting and UE Radio Capability information associated with the UE, wherein the UE Radio Capability information indicates whether the CE mode B is supported by the UE or not supported by the UE;
determining, based on the usage setting of the UE indicated by a Non-Access Stratum (NAS) message from the UE, a change of the usage setting of the UE from a data centric usage setting to a voice centric usage setting or from the voice centric usage setting to the data centric usage setting; and
in response to determining the change of the usage setting of the UE, generating an S1AP message to request UE Radio Capability information from the UE; and
network controller circuitry communicatively coupled with the processor circuitry, the network controller circuitry configured to perform operations comprising:
receiving the NAS message from the UE; and
transmitting the S1AP message to a base station such that the base station is triggered to request UE Radio Capability information from the UE.
