Abstract: A core network node includes a transmitter configured to transmit a control plane data back-off timer to restrict a request from a UE for data transmission via Control Plane CIoT EPS Optimization. A UE includes a receiver configured to receive a control plane data back-off timer from a core network node, and a controller configured to not initiate data transmission via Control Plane CIoT EPS Optimization while the control plane data back-off timer is running.

Abstract: A communication system is disclosed in which a control node generates configuration data for each of a plurality of MMEs operating in overlay networks. The configuration data defines a type of user equipment (UE) or a type of UE traffic to be serviced by each MME. The MME configuration data is provided to a base station and used to control selection of an MME to service a request from a UE. The control node monitors network traffic within and across the overlay networks and can reconfigure one or more MMEs to service different UE traffic types. This allows for improved flexibility in load balancing with overlay networks

Abstract: A wireless terminal can communicate with two radio access networks (RAN) (304, 306) of different types. The wireless terminal can register simultaneously with a RAN of the first type and a RAN of the second type and can wirelessly connect to a RAN of either the first type or the second type in a connected state. The wireless terminal when registered with both a first RAN and a second RAN and when wirelessly connected to the first RAN in the connected state, receives a mobility signal via the first RAN indicating a RAN of the second type and, in response to receiving the mobility signal and in response to being so registered with the first RAN and second RAN, transmits an access trigger signal (417). The access trigger signal indicates that the wireless terminal is to be connected to the second RAN in the connected state.

Abstract: The method includes sending a registration request message. The registration request message includes first 5G Globally Unique Temporary Identifier (5G-GUTI), a first Non-Access-Stratum (NAS) container, second 5G-GUTI, and a second NAS container. The first NAS container includes a first integrity protected registration request message. The first integrity protected registration request message is the registration request message which is integrity protected based on a first NAS security context. The second NAS container includes a second integrity protected registration request message. The second integrity protected registration request message is the registration request message which is integrity protected based on a second NAS security context.

Abstract: [Problem]
This disclosure proposes solutions for some situations in the 3GPP nodes or some situations in the connection between the 3GPP nodes during the Network Slice Admission Control (NSAC) procedure.
[Solution]
An Access and Mobility Management Function (AMF) device for communicating with a User equipment (UE) and a Network Slice Admission Control Function (NSACF) device includes a receiver and a transmitter. The receiver is configured to receive, from the UE, a Registration Request message including first information indicating whether the UE supports a first function and requested Network Slice Selection Assistance Information (NSSAI). The transmitter is configured to transmit, to the UE, a Non-Access Stratum (NAS) message including a rejected NSSAI including a first cause value and a back-off timer value if the UE supports the first function. The transmitter is configured to transmit, to the UE, the NAS message including a rejected NSSAI including a second cause value if the UE does not support the first function.
