摘要： 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.

摘要： A fifth-generation core network (5GC) provides 5G radio access network (RAN) services to a user equipment (UE) in a time-sensitive communications (TSC) network (TSN). This includes receiving a protocol data unit (PDU) session establishment request from the UE, the PDU session establishment request including an industrial Internet of Things (IIoT) vertical or application type, identifying a TSN application function (AF) relating to the IIoT vertical or application type, determining quality of service (QoS) parameters for communications between the UE and the 5G RAN based on the identified TSN AF, the QoS parameters including a survival time for the IIoT vertical or application type and establishing a PDU session with the UE when the QoS parameters including the survival time are satisfied.

摘要： Disclosed are systems, methods, integrated circuits and computer readable storage media for configuring time sensitive communications (TSC). The configuring of the TSC includes monitoring, by a user plane function (UPF), a source and destination of packets in a first protocol data unit (PDU) session of a first user equipment (UE) and in a second PDU session of a second UE, pairing a first device side TSN translator (DS-TT) port of the first UE with a second DS-TT port of the second UE when the first PDU session and the second PDU session are served by the same UPF, wherein the pairing is based on the monitoring of the first and second PDU sessions and when the first DS-TT and second DS-TT ports are paired, communicating the packets between the first UE and the second UE in a UE-UE communication without traversing the TSN.

摘要： A user equipment (UE) is configured to connect to a next generation nodeB (gNB) and further UE. The UE determines that a triggering event has occurred, wherein the triggering event is based on a set of proximity services (ProSe) path selection and switching (PSS) policies, transmits a setup or update request to a direct discovery name management function (DDNMF) of a 5G core network, receives UE-specific policies based on the set of ProSe PSS policies, and switches from one of a PC5 interface or a Uu interface to another one of the PC5 interface or the Uu interface.

摘要： The present application relates to improving a roaming service. In an example, a home network of a user equipment (UE) defines a first set of UE route selection policy (URSP) rules for managing traffic of the UE when connected to the home network. While roaming, the UE is connected to a visited network. Based on the first set of URSP rules and guidance information of the visited network indicating one or more URSP rules that the visited network can support for the UE, the home network defines a second set of URSP rules for managing traffic of the UE while roaming. The home network sends, via the visited network, the second set of URSP rules to the UE as rule information for use by the UE while connected to the visited network.

摘要： Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to adaptively manage system information, particularly on-demand system information. A UE may receive mandatory system information from a wireless network and may determine that at least some additional, e.g., on-demand, system information would be beneficial. The UE may evaluate whether a condition is met to request the additional system information and may initiate a random access procedure to request the additional system information. If the random access procedure fails, the UE may adjust its behavior, including reselection behavior, in response to lacking the additional system information.

摘要： 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.
