According to some embodiments, a MME of a first PLMN may receive an LTE NAS request corresponding to a tracking area from a wireless device. The MME may determine to reject the request, and may send a rejection response to the request indicating that access to the first PLMN in the tracking area according to LTE is not available to the wireless device. The rejection response may further include extended cause information relating to whether or not the wireless device is permitted to access the first PLMN in other tracking areas according to LTE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mitigating no-service delays for LTE capable wireless devices without LTE access permission","description":"This disclosure relates to reducing or mitigating no-service delays for LTE capable wireless devices which do not have permission to access one or more LTE networks.
