Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

Abstract: A user equipment (UE) may update multicast-broadcast key for securing a data session for a multicast or broadcast service. The UE may receive a multicast-broadcast key for the for a multicast or broadcast service carried by a radio bearer (RB) associated with the data session. The UE may receive packets for the multicast or broadcast service. The UE may decode the packets using the multicast-broadcast key, or a key derived from the multicast-broadcast key. The UE may receive an updated multicast-broadcast key for the multicast or broadcast service. The UE may decode the packets for the multicast or broadcast service received on the RB using the updated multicast-broadcast key, or a key derived from the updated multicast-broadcast key.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that improve data packet exchange between a UE in an inactive mode and a network. In certain configurations, the apparatus may receive, from a user equipment (UE) in an active mode, a first packet including a first identifier associated with an anchor base station, a second identifier associated with a UE context, and a payload. The apparatus may identify the anchor base station based at least in part on one or more of the first identifier associated with the anchor base station or the second identifier associated with the UE context. The apparatus may transmit a second packet to the anchor base station. The second packet may include at least a portion of the first packet.

Abstract: Certain aspects of the present disclosure provide techniques for managing security keys for enciphering and deciphering packets transmitted in a wireless communications system. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes obtaining an indication of a key area identifier (ID) of a first cell node, wherein the key area ID identifies a set of cell nodes that are associated with a network node that uses a first key for enciphering or deciphering messages and communicating a first set of messages with the first cell node using the first key for enciphering or deciphering the first set of messages.

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: A method, an apparatus, and a computer program product for wireless communication are provided. A method includes transmitting a request to a serving network with a nonce and a signature request directed to a network function of the serving network, receiving a response to the request from the serving network, and authenticating the serving network based on the signature of the network function. The nonce may provide replay protection. The response may include a signature of the network function. The request sent to the serving network may include a radio resource control (RRC) message or a tracking area update (TAU) request. The serving network may be authenticated using a trusted third party to verify a certificate associated with the serving network.
