    Abstract: Techniques described herein may enable Evolved Packet Core (EPC) devices (e.g., Mobility Management Entities (MMEs), Serving Gateways (SGWs), or Packet Data Network Gateways (PGWs)) to transfer a connection with a User Equipment (UE) from one EPC device to another EPC device without a break in service for the UE. The transfer may occur in response to an EPC device being overloaded, an EPC device being added or removed from a logical group of EPC devices, or in response one EPC device becoming more appropriate for the UE than another EPC device (e.g., due to a change in the geographic location of the UE). EPC devices may be implemented as virtual network functions, and the transfer of the UE may occur while the UE is in an active mode or an idle mode.

    Abstract: Technology for providing core network assistance information from a mobility management entity (MME) in an evolved packet core (EPC) is disclosed. An average radio resource control (RRC) connected state time for a UE is determined. An average RRC idle state time for the UE is also determined. An amount of time that the UE spends in cells of the EPC is identified to determine a number of handover procedures between cells in a selected time period. The core network assistance information communicated to a serving eNB of the UE to enable the serving eNB to reduce UE state transitions for the UE.

    Abstract: Apparatuses of wireless communication systems are disclosed. A User Equipment (UE) stores an enhanced coverage restricted parameter from a Mobility Management Entity (MME), and operates in the enhanced coverage mode if the enhanced coverage restricted parameter indicates that the UE is not restricted. The MME decodes an enhanced coverage restricted parameter received from a Home Subscriber Server (HSS), and generates a message to send the enhanced coverage restricted parameter to the UE. An eNode B decodes a message from the UE, the message indicating that the UE supports restriction for use of enhanced coverage. The eNB decodes an S1 Application Protocol (S1-AP) initial context set-up request message configured to indicate an enhanced coverage restricted parameter, the message received from the MME. The eNB operates in the enhanced coverage mode for the UE unless the enhanced coverage restricted parameter indicates that the enhanced coverage is restricted.

    Abstract: Technology for a mobility management entity (MME) operable to facilitate paging message transmissions using a user equipment (UE) location is disclosed. The MME can process data received for a user equipment (UE) from a Service Capability Exposure Function (SCEF). The downlink data can include a public land mobile network (PLMN) UE location associated with the UE location. The MME can compare at least one of a time stamp and a granularity level of the PLMN UE location to existing location area information for the UE. The MME can determine to overwrite the existing location area information for the UE with the PLMN UE location. The UE can generate a paging message for transmission only to an eNodeB associated with the PLMN UE location, and the eNodeB can be configured to forward the paging message to the UE.
