Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.

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: A UE may move out of range of a network. Accordingly, the UE may use a relay node to communicate. To manage the relay node, a wireless device such as the UE may receive a relay search message from a second UE requesting a relay UE to establish a connection to the network through the relay UE. The UE may transmit a message to a base station informing the base station of the relay search message from the second UE. The UE may receive an initiate relay association procedure message from the base station, the initiate relay association procedure message informing the first UE that the first UE has been selected by the base station to initiate a relay association procedure with the second UE. The UE may transmit a relay association message to the second UE including a request to be the relay UE for the second UE.

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: 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.
