Abstract:
Embodiments of the present disclosure describe methods, apparatuses, and systems for management of voice services for user equipments (UEs) in coverage enhancement (CE) mode B. A cellular protocol stack (CPS) of the UE may indicate to an internet protocol (IP) multimedia services (IMS) circuitry of the UE that the UE is operating in the CE mode B (or will be operating in the CE mode B when it awakes from idle mode). The IMS circuitry may receive an SIP invite from an IMS server to invite the UE to engage in a mobile terminated (MT) call. In response to the SIP invite, the IMS circuitry of the UE may reject the SIP invite and deregister the UE from voice services. Other embodiments may be described and claimed.
