Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating a routing ID associated with a user equipment in a wireless network. An exemplary method generally includes receiving a downlink control plane message including updated configuration information for a Unified Data Management (UDM) entity in the network; determining whether a universal subscriber identification module (USIM) of the UE supports one or more parameters stored in the USIM to be updated; based on the determination, storing the received configuration information in at least one of: the USIM if the USIM supports the one or more parameters to be updated; or memory of the UE if the USIM does not support the one or more parameters to be updated; generating an identifier for the UE based on the stored updated configuration information; and transmitting at least one message using the generated identifier.

Abstract: Disclosed are techniques for supporting inter-RAT mobility of a UE in an eCall-only mode. In an aspect, the UE establishes a communication session for an eCall or a test/reconfiguration call, releases the communication session for the eCall or test/reconfiguration call, starts a timer based on at least one of (i) release, by the UE, of a PS signaling connection for a UMTS access for the communication session, (ii) expiration at the UE of a READY timer for GPRS, wherein the READY timer was started by the UE following a PS handover of the communication session from an LTE access to a GSM-GPRS access, (iii) intersystem change by the UE from an LTE access to a GSM-GPRS access or a UMTS access, or (iv) intersystem change by the UE from a GSM access or a UMTS access to an LTE access, and performs an eCall inactivity procedure when the timer expires.

Abstract: Techniques are described for wireless communication. A wireless device may generate a secured query message based at least in part on a security credential of the wireless device. The secured query message may be generated prior to performing an authentication and key agreement (AKA) with a network. The wireless device may transmit the secured query message to the network, and receive a response to the secured query message. The wireless device may then determine whether or not to perform the AKA with the network based on the received response (e.g., the wireless device may determine whether or not the response is associated with the security credential of the wireless communication device and a network security credential of the network). The wireless device may establish a secure connection with the network or refrain from considering the response based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques for selecting policies for routing of data traffic. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes selecting at least one policy for routing of data traffic to a network, wherein the policy comprise an access network discovery and selection policy (ANDSP) if the UE has the ANDSP provisioned regardless of whether the UE is registered to evolved packet core (EPC) or fifth-generation core network (5GCN), and communicating the data traffic to the network based on the selection.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Aspects directed towards steering of roaming (SoR) are disclosed. In one example, a communication from a public land mobile network (PLMN) is received by a user equipment (UE) in which the communication indicates an acceptance of a UE registration with the PLMN. This example further includes performing a determination of whether an SoR indicator associated with a home PLMN (HPLMN) is embedded within the communication. The UE then manages PLMN selection according to the determination. In another example, a UE is configured to operate according to an SoR configuration in which the UE is configured to ascertain whether an SoR indicator is embedded within a communication from a PLMN. An SoR indicator associated with an HPLMN is then generated and subsequently transmitted from the HPLMN to the UE via the PLMN.

Abstract: Methods, systems, and devices are described for improving resource management in wireless communications. More particularly, the methods systems and devices relate to techniques for suspending bearers when not required, for example, for D2D communications. In one example, a mobile device may send a connection request that indicates a service type. The connection request may be a service request (SR) or an extended service request (ESR). A set of bearers may be established for the intended communication(s). The indicated service type may not require all bearers of the set of bearers such that at least one bearer may be suspended.

Abstract: Aspects encompassing public land mobile network (PLMN) configurations are disclosed. In one example, first and second PLMN configurations are determined, and a parameter having a common identifier between a hybrid PLMN and a PLMN from a different PLMN configuration is identified, such that the hybrid PLMN may connect with a first or second core network type. Inclusion of the common identifier is limited to either the first or second PLMN configuration via an index, and the first and second PLMN configurations are transmitted. In another example, first and second PLMN configurations are received, and a hybrid PLMN in one of the two PLMN configurations is selected. A determination is made whether to use the hybrid PLMN to connect with a first or second core network type. Whether a hybrid PLMN parameter was ascertained via the first or second PLMN configuration is reported. Other aspects, embodiments, and features are also included.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enabling access control in a connected mode, idle mode, and an inactive state. An exemplary method generally includes receiving access control information associated with one or more services used by the UE for communicating with the wireless communications network, receiving a request to transmit traffic using the one or more services, checking a type of the traffic against the access control information, and scheduling the traffic for transmission if the type of the traffic satisfies one or more criteria in the access control information based on the checking.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device transmits an indication of whether the device should be paged over a 3GPP access when a core network has data ready to transmit for PDU sessions over a non-3GPP access. A session management function (SMF) of the core network receives a data notification indicating that the core network has data ready to transmit to the wireless device for a PDU session over the non-3GPP access. The SMF determines whether to transmit a paging request to an access and mobility management function (AMF) of the core network based on a paging state of the SMG, a paging state of the wireless device, or a connection management idleness state of the wireless device. The AMF determines whether to transmit a paging message to the wireless device.

Abstract: A core network (CN) may establish and distribute a quality of service (QoS) policy across a wireless communication system, e.g., by sending QoS policy information to an access network and to user equipment. The QoS policy may be implemented with respect to data network (DN) sessions as well as data sessions. For each DN session or data session, the QoS policy may be applied by explicit or implicit request, and data sessions may in some examples utilize pre-authorized QoS policies without the need to request the QoS. Other aspects, embodiments, and features may also be claimed and described.

Abstract: Protected configuration data may be sent to user equipment subscribed to a first wireless communication network by a second wireless communication network with which the user equipment is registered. The first wireless communication network may protect the configuration data based on at least one first key when sending the data to the second wireless communication network. The second wireless communication network may send the configuration data to user equipment in messages protected by at least one second key. User equipment receives the message from the second wireless communication network, extracts the configuration data using the at least one second key, determines whether the configuration data has been altered at least in part based on the at least one first key, and applies the configuration data if the configuration data has not been altered. The protected configuration data may be sent in an information element of a control plane message.

Abstract: Methods and apparatus supporting multiple concurrent service contexts sharing a single connectivity context are disclosed. A device may initiate a radio link with a network node and establish a connectivity context with the network node over the radio link using a connectivity logical context of the device. The network node may receive, authenticate, and authorize context establishment requests. A first service context with a first service management entity may be established over the radio link using a first logical context of the device, where the first logical context is distinct from the connectivity logical context. Multiple service connections using multiple service contexts based on multiple logical contexts of the device may share the connectivity context and may be established over the radio link.
