Abstract: The exemplary embodiments relate to implementing network slice aware cell selection at a user equipment (UE). This may include receiving information indicating that a cell of a network supports a network slice. The UE may identify that the UE is located within the coverage area of the cell and determine whether measurement data corresponding to the cell satisfies predetermined criteria. when the measurement data satisfies the criteria, the UE may camp on the cell.

Abstract: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Abstract: A network component communicating with a user equipment (UE) and a server. The network component receives a first packet from the UE, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, receives a second packet from the server and determines whether to transmit a signal to the UE based on the second packet received from the server. A UE having a transceiver and a processor. The UE transmits a first packet to the network component, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, identifies an out of service (OOS) event, receives registration information from the network component and registers with the server based on the registration information received from the network component.
