Third generation partnership project ("3 GPP"), fifth generation core ("5 GC"), access and mobility management function ("AMF"), access point name ("APN"), access layer ("AS"), application programming interface ("API"), service support system ("BSS"), data network name ("DNN"), downlink ("DL"), enhanced mobile broadband ("eMBB"), evolved node B ("eNB"), evolved packet core ("EPC"), evolved UMTS terrestrial radio access network ("E-UTRAN"), fully qualified domain name ("FQDN"), home subscriber server ("HSS"), IP multimedia subsystem ("IMS", also called "IP multimedia core subsystem"), internet protocol ("IP"), long term evolution ("LTE"), LTE advanced ("LTE-a"), media access control ("MAC"), mobile network operator ("MNO"), mobility management entity ("MME"), non-access layer ("NAS"), narrowband ("NB"), network function ("NF"), network access identifier ("NAI"), next generation (e.g., 5G) node B ("gcnb"), next generation radio access network ("NG-RAN"), new radio ("NR"), operations management and maintenance ("operation and maintenance") Policy control function ("PCF"), packet data network ("PDN"), packet data unit ("PDU"), PDN gateway ("PGW"), public land mobile network ("PLMN"), quality of service ("QoS"), radio access network ("RAN"), radio access technology ("RAT"), radio resource control ("RRC"), reception ("Rx"), single network slice selection assistance information ("S-NSSAI"), serving gateway ("SGW"), session management function ("SMF"), subscription permanent identifier ("SUPI"), transmission control protocol ("TCP"), transmission ("Tx"), unified data management ("UDM"), user entity/device (mobile terminal) ("UE"), uplink ("UL"), user plane ("UP"), universal mobile telecommunications system ("UMTS"), user datagram protocol ("UDP"), wireless local area network ("WLAN"), and worldwide interoperability for microwave access ("WiMAX"). In some embodiments, a non-public network (NPN) is deployed to serve private (i.e., non-public) customers and/or services. The NPN can also provide public services (public telephone service or emergency service) if it agrees with the PLMN or accesses the PSTN. Disclosure of Invention Methods for provisioning information to a UE to access a particular service are disclosed. The apparatus and system also perform the functions of these methods. A method for a UE, for example, for provisioning the UE with information to access a particular service, includes sending a first registration request to a mobile communication network, the mobile network supporting a plurality of network slices. The method includes receiving configuration information from a mobile communication network, the configuration information enabling a UE to use at least one network slice from a plurality of network slices, wherein the configuration information includes a frequency priority for the at least one network slice. The method comprises performing cell reselection using at least the frequency priority, and sending a second registration request to the mobile communication network after performing cell reselection, wherein the second registration request is registered with the at least one network tile. A method of AMF, for example, for provisioning a UE with information to access a particular service, includes receiving a first registration request to register the UE with a mobile communication network. The method includes receiving subscription information of a UE from a mobile communication network and determining configuration information of the UE to be provisioned. Here, the subscription information and the configuration information enabling the UE to use the specific service include at least a frequency priority for each of the plurality of network slices. The method includes provisioning the UE with the configuration information and receiving a second registration request from the UE in response to provisioning the UE. A method of UDM, for example, for provisioning a UE with information to access a particular service, includes storing at least default subscription information for the UE and updated subscription information for the UE. Here, the default subscription information enables the UE to access the default service, and the updated subscription information enables the UE to use the specific service. The method includes receiving a request from the AMF for subscription data for the UE, and determining that the UE needs to provision and determine a type of subscription data to send to the AMF. Here, the type of subscription data may be default subscription information or updated subscription information. The
