Abstract: Methods, systems, and devices for wireless communications are described that supports connectivity to a core network via an access network. A user equipment (UE) may establish connectivity with an access network and perform a discovery procedure to identify and select a packet data gateway that provides connectivity to a core network via a core network node. The UE may perform an authentication procedure with the core network node via the packet data gateway to be authenticated with the core network for establishing connectivity with the packet data gateway. The UE may receive a set of control plane addressing information via the packet data gateway corresponding to a secure tunnel established between the UE and the packet data gateway. The UE may perform an attach procedure via the secure tunnel with the core network node without re-authenticating the UE.

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: Certain aspects of the present disclosure relate to techniques selecting a core network. As described herein, a user equipment (UE) may receive an indication of services provided by a first core network (CN). The UE may take action to reselect from the first CN to a second CN to access a set of services not provided by the first core network. When a UE desires services not available on a currently-connected CN, the UE may transmit an establishment request message requesting the services desired.

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: A method, operational at a device, includes receiving at least one packet belonging to a first set of packets of a packet flow marked with an identification value, determining that the at least one packet is marked with the identification value, determining to change a quality of service (QoS) treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received, and sending a request to change the QoS treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received to trigger a different QoS treatment of packets within the packet flow, responsive to determining to change the QoS treatment. Other aspects, embodiments, and features are also claimed and described.

Abstract: In one aspect, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may receive a registration request including requested features by a UE. The apparatus may determine to reject the registration request based on the requested CIoT optimization features. The apparatus may select a cause value from a plurality of cause values to include in a registration reject message to the UE. The apparatus may send the registration reject message to the UE.

Abstract: Techniques are described herein to communicate policy information and policy information requests between user equipments (UEs) and a core network using control plane signaling. In some examples, non-access stratum (NAS) messages may be used to communicate policy information requests from a UE to the core network. Similarly, NAS messages may be used to communicate up-to-date policy information from the core network to the UE. In some examples, the core network may include number of functions to manage the communication of policy information with the UE. In some examples where the UE is roaming away from its home network, the core network may engage in additional signaling to pass policy information to the UE.

Abstract: Methods, systems, and devices for wireless communication are described for inter-RAT mobility from a first radio access technology (RAT) to a second RAT, including cases in which different RATs correspond to different generations of networks. Approaches described herein include providing a preemptive indication of inter-RAT mobility for one or more geographic areas such to a user equipment (UE). The UE can thus use a mobility procedure to transition from the first RAT to the second RAT that is supported in the UE's location without first attempting an unsupported mobility procedure, reducing transition latency.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Aspects described herein relate to reporting user equipment (UE) activity period statistics. Statistics for a UE regarding a time the UE is in a connected mode or idle mode during one or more activity periods can be determined. From the statistics for the UE, it can also be determined whether the time the UE is in the connected mode in the one or more activity periods is less than a threshold. At least a portion of the statistics for the UE can be provided to an access network node where the time the UE is in the connected mode in a corresponding portion of the one or more activity periods is less than the threshold.
