Abstract: Methods and devices for selecting an edge application server (EAS) to service a user equipment (UE). One exemplary method incudes determining that a current protocol data unit (PDU) session of an application being executed by a UE is being serviced by a first EAS, determining that the first EAS is no longer suitable to service the application, selecting a second EAS to service the application and instructing the UE to use the second EAS for future PDU sessions for the application.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN) dedicated to an international area. The UE receives a downlink message from the NTN, where the downlink message includes a public land mobile network (PLMN) identifier of a first PLMN of the NTN including an information element (IE). The IE indicates that the NTN is dedicated to an international area. Responsive to receiving the downlink message, the UE determines a current location of the UE and determines whether the current location is in the international area. The UE provides an international area notification to an access and mobility management function (AMF) servicing the UE to forward to a home PLMN (HPLMN) of the UE indicating whether the current location is in the international area.

Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.

Abstract: Computer systems and methods are described for operating a network data and analytics function (NWDAF) in a cellular core network. The NWDAF receives user equipment (UE) mobility information from a first network function of the cellular network system and receives edge application server (EAS) information from a second network function of the cellular network system. The NWDAF derives data analytics based at least in part on the UE mobility information and the edge application server information. The NWDAF receives a request for the data analytics from a third network function in the cellular network system, and provides the data analytics to the third network function.

Abstract: A cellular network includes a first network component configured to i) identify a first session between a first data network and a user equipment (UE), wherein the first session corresponds to a first session management function (SMF), ii) receive data network access information (DNAI) from a network function, the DNAI corresponding to a second data network and iii) select a second SMF that is to be utilized for a second session between the second data network and the UE. The cellular network also includes a second network component configured to i) store a mapping between the DNAI and the second SMF and ii) transmit an indication of the second SMF to the first network component, wherein the first network component selects the second SMF based on the indication.

Abstract: This disclosure relates to techniques for determining a radio access technology to prioritize when obtaining cellular service in a wireless communication system. A wireless device may determine whether to deprioritize obtaining cellular service using a radio access technology. Whether to deprioritize obtaining cellular service using the RAT may be determined based at least in part on one or more cellular network characteristics. The wireless device may establish a wireless link with a cellular base station. The wireless link may be established with the cellular base station based at least in part on the determination of whether to deprioritize obtaining cellular service using the radio access technology.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN). A UE performs a non-access stratum (NAS) procedure with a public land mobile network (PLMN) of an NTN. The UE receives a NAS message from the PLMN, and the NAS message indicates that the UE is not allowed to access a core network of the NTN. The NAS message may indicate that the UE is not allowed to access the core network of the NTN because a location of the UE is unknown to the NTN, that access to the NTN is not allowed in a country in which the UE is located, or that a location of the UE is not within a country associated with the NTN. The UE modifies its PLMN search procedure responsive to receiving the NAS message.

Abstract: Systems and methods are provided to improve candidate search and measurement in non-standalone (NSA) and standalone (SA) 5G new radio (NR) multi-radio access technology (RAT) environments. For Evolved Universal Terrestrial Radio Access Network (E-UTRAN) NR-dual connectivity (EN-DC), a user equipment (UE) skips 5G band measurements for an initial search or an out-of-service (OOS) search. For SA dual connectivity, the UE avoids 5G remaining band (RBS) scans and limits 5G deviated band search (DBS) scans to bands configured for the carrier.
