1. A method comprising:
receiving, by an access and mobility management function (AMF) from a wireless device, a registration request indicating one or more requested network slices;
sending, by the AMF to a network slice selection function (NSSF), a slice selection request indicating the one or more requested network slices;
receiving, by the AMF from the NSSF:
an indication of a first allowed network slice of the one or more requested network slices;
an indication of a second allowed network slice of the one or more requested network slices; and
a time-based network slice coexistence rule indicating a time duration during which the first allowed network slice and the second allowed network slice are concurrently usable;
sending, by the AMF to the wireless device, at a first time, not within the time duration, a slice selection response indicating acceptance of the first allowed network slice and the second allowed network slice;
enforcing, by the AMF, at a second time, not within the time duration, the time-based network slice coexistence rule, wherein the enforcing comprises one or more of:
initiating a network slice handover, modification, or deletion of the first allowed slice; or
initiating a packet data unit (PDU) session establishment, modification, or deletion of a PDU session of the wireless device.
