The wireless device determines to establish a PDU session for a network slice associated with a service of the communication service provider. The wireless device sends to a session management function a first message requesting establishment of the PDU session, the first message comprises a single network slice selection assistance information of the network slice and an identifier of the communication service provider. The wireless device receives from the SMF a second message accepting the establishment of the PDU session.

Abstract: A wireless device in an RRC connected state receives a radio resource control (RRC) message from a base station. The wireless device transitions from the RRC connected state to an RRC inactive station in response to the RRC message. The RRC message indicates an active time period in which the wireless device is reachable by paging. The wireless device monitors to receive a paging message during the active time period after the transitioning. The wireless device activates a mobile initiated communication only (MICO) mode in response to an expiration of the active time period. The wireless stops monitoring for the paging message in response to the expiration of the active time period.
