An AMF sends a first request message to an NSSF for at least one network slice information for a wireless device. The AMF receives from the NSSF, location based network slice coexistence rule(s) for location(s) of the wireless device. The location based network slice coexistence rule(s) are for allowed network slice information that is a subset of the network slice information. The AMF receives from the wireless device being at a first location, a second request message for a first network slice for the wireless device. The AMF determines to accept the first network slice based on the first location and the location based network slice coexistence rule(s). The AMF sends to the wireless device, a first response message indicating acceptance of the first network slice.
