A user equipment (UE) may receive a list of Public Land Mobile Networks (PLMNs) that support a given network slice in a given country, different from a home country of a home PLMN of the UE. When roaming in the given country, UE may access a PLMN of the list if the given network slice is desired. The list may be provided by the home PLMN: while the UE is in the home country; or via a visited PLMN while the UE is in the given country. The list may be received in response to a UE-initiated request, or pushed to the UE by the home PLMN. A validity timer period received with the list may indicate a duration of validity of the list. In an alternative scenario, the UE may receive the list from an entitlement server, e.g., one belonging to a visited PLMN.

Selection of slice-supporting PLMNs while roaming away from home network

Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.

Steering of roaming PLMN list update and management

A user equipment (UE) displays a list of available networks for manual network selection. The UE detects multiple networks during a public land mobile network (PLMN) scan, wherein the multiple networks include one or more PLMNs and one or more stand-alone non-public networks (SNPNs), generates a manual network selection list that includes at least i) the one or more PLMNs or ii) the one or more SNPNs, determines a sequence in which entries of the manual network selection list are to be displayed at the UE, displays a graphical user interface (GUI) that includes a representation of the manual network selection list and registers with one of the multiple networks in response to user input.

Manual network selection at a user equipment

Embodiments described herein relate to wireless communications, including methods and apparatus for dynamically selecting subscriber identity module (SIM) profiles, electronic SIM (eSIM) profiles, multi-SIM operating modes, and/or wireless access networks for network slice based applications of wireless devices. A wireless device can include at least two SIM/eSIM profiles and switch use of SIM/eSIM profiles, change between dual SIM operating modes, and/or select a registration mode based on requirements of one or more applications in use and availability of network slices via different wireless networks.

Dynamic profile and radio access technology selection based on application network slice requirements

Several techniques using a network slice quota (NSQ) management function provide dynamic adjustment in order to meet the limitation of data rate per network slice in the uplink and downlink wireless connections in a wireless network. In one technique, when the limit is reached, the session aggregated maximum bit rates (AMBR) per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per user equipment (UE). In another technique, when the limit is reached, there is a proportionate equivalent increment and decrement of session AMBR based on usage patterns of the subscription levels. In a further technique, when the limit is reached, there is a proportionate equivalent increment and decrement of slice resources based on usage patterns. In yet another technique, a quota update is attempted using the Unified Data Repository (UDR).

Apparatus and method for dynamic data rate adjustment for a wireless slice

Techniques discussed herein facilitate configuration of network slices for a User Equipment (UE) supporting constraints on simultaneous operation of slices. Such a technique may comprise: receiving a registration request message to request registration on a set of requested network slices; registering the UE to a set of allowed network slices; and generating a registration accept message for transmission indicating the UE is registered to the set of allowed network slices, wherein the registration accept message indicates slice compatibility information for each allowed network slice of the set of allowed network slices for the UE, wherein the slice compatibility information for each allowed network slice indicates whether or not other configured network slices of a set of configured network slices are compatible with the configured network slice for simultaneous operation by the UE.

Network (NW) techniques for constraints on simultaneous use of network slices

A user equipment (UE) that is registered to a stand-alone non-public network (SNPN) can also access services on a public land mobile network (PLMN). The UE accesses the PLMN by transmitting a first signal to a data network, receiving a second signal from the data network in response to the first signal, wherein the second signal identifies a PLMN that is configured to be accessed by the UE via the data network and transmitting a session initiation protocol (SIP) registration request to the PLMN via the data network.

Public land mobile network support for a stand-alone non-public access network

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.

Public land mobile network selection for non-terrestrial networks

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.

Time sensitive communications between user equipment

Techniques discussed herein facilitate configuration of network slices for a User Equipment (UE) supporting constraints on simultaneous operation of slices. One example embodiment is a UE device configured to: transmit a registration request message to request registration on a set of requested network slices; and receive a registration accept message indicating the UE is registered to a set of allowed network slices, and wherein the registration accept message indicates slice compatibility information for each allowed network slice of the set of allowed network slices for the UE, wherein the slice compatibility information for each allowed network slice indicates whether or not other configured network slices of the set of configured network slices are compatible with the configured network slice for simultaneous operation by the UE.

User equipment (UE) techniques for constraints on simultaneous use of network slices

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.

Selection of edge application server

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.

Traffic routing towards local area data network per application function request

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.

Non-terrestrial networks for international areas

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.

Systems and methods to indicate emergency services support for roaming users

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.
