Abstract: User equipment receives and stores configuration information for selection of an evolved packet data gateway (ePDG). The ePDG configuration information includes one or more parameters relating to identification and functions of ePDGs in an HPLMN and/or in one or more VPLMNs. When the UE performs ePDG selection, the UE accesses the ePDG configuration information and then selects an ePDG for access to a core packet network using the ePDG configuration information.

Abstract: Various communication systems may implement network management tools to help manage registration requests from a user equipment. For example, network functions in a communication system with a shared data layer may be used to manage requests from the user equipment. A method may include transmitting a request from a user equipment to a network function. The method may also include receiving at the user equipment a temporary identification from the network function The temporary identification comprises an identifier that helps locate a shared data layer function that stores context information for the user equipment. In addition, the method may include transmitting from the user equipment a subsequent request comprising the temporary identification to another network function or the network function.

Abstract: A non-access stratum (NAS) control protocol includes procedures for control plane cellular internet of things (CP-CIoT) service requests and attach request. UE in idle mode may transmit an NAS service request message including user data to a mobility management entity (MME) over the control plane. The MME extracts the user data from the NAS service request message and determines a type of the user data. The MME may forward non-IP data to a Service Capability Exposure Function (SCEF) and forward IP data to a packet gateway.
