    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, devices may use information protection to detect fake base stations. A base station verified by a network may transmit first information to a user equipment (UE) in an unprotected message. If a fake base station intercepts and modifies the message before relaying the message to the UE, the UE may receive different information than the transmitted first information. The UE may then transmit an indication of the received information to the verified base station in a protected message. In some cases, based on the indication, the verified base station may re-transmit the first information to the UE in a message protected against modification by the fake base station. If the UE determines that the initially received information is different from the information received in the protected retransmission, the UE identifies message modification by the fake base station.

    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: Aspects of security schemes (e.g., integrity protection, encryption, or both) are described. A measure of access stratum security can be realized without overhead associated with establishing and/or maintaining the per-cellular-device access stratum security context at a Cellular Internet of Things (CIoT) base station (C-BS). A gateway (e.g., a CIoT Serving Gateway Node (C-SGN)) may derive a first key. The first key may be only known to the C-SGN. The C-SGN may derive a second key from the first key and a parameter unique to the C-BS. The C-SGN may also derive a third key from the second key and an identity of a cellular device. The C-SGN may send the second and third keys to the C-BS and cellular device, respectively. Small data messages encrypted and/or integrity protected by the cellular device may be decrypted and/or verified by the C-BS.

    Abstract: A device that identifies entry into a new service area, transmits a service area update request to a network device associated with a network, receives a control plane message from the network indicating control plane device relocation or a key refresh due to a service area change in response to transmitting the service area update request, and derives a first key based in part on data included in the control plane message and a second key shared between the device and a key management device. Another device that receives a handover command from a network device associated with a network, the handover command indicating a new service area, derives a first key based on data included in the handover command and on a second key shared between the device and a key management device, and sends a handover confirmation message that is secured based on the first key.

    Abstract: In an aspect, a network supporting a number of client devices includes a network device that generates a context for a client device. The client device context may include network state information for the client device that enables the network to communicate with the client device. The client device may obtain, from a network device that serves a first service area of the network, information that includes a first client device context. The client device may enter a second service area of the network served by a second network device. Instead of performing a service area update procedure with the network, the client device may transmit a packet in the different service area with the information that includes the client device context. The client device may receive a service relocation message including information associated with the different network device in response to the transmission.

    Abstract: Systems and techniques are disclosed to facilitate the sponsored connectivity of a user equipment on a serving network so that the UE may access a service whose connectivity is sponsored by an application service provider. The application service provider provisions the serving network so that it is aware of the sponsored connectivity. In an attach attempt to the serving network, the UE provides a client token based on a pre-existing credential (established between the UE and the application service provider) instead of a subscriber identifier with the attach request. The application service provider's server validates the access credential to authenticate the UE and provides information that the serving network uses to mutually authenticate with the UE. The UE may then use the serving network to access the service via the sponsored connection, even where the UE does not have a subscriber identity and subscription with a cellular network.

    Abstract translation: 公开了系统和技术以促进服务网络上的用户设备的赞助连接，使得UE可以访问由应用服务提供商赞助其连接的服务。 应用服务提供商规定服务网络，以便它知道赞助的连接。 在对服务网络的附着尝试中，UE基于预先存在的凭证（在UE和应用服务提供商之间建立）而不是具有附加请求的订户标识符来提供客户端令牌。 应用服务提供商的服务器验证访问凭证以验证UE，并提供服务网络用于与UE相互认证的信息。 UE然后可以使用服务网络经由赞助的连接来访问服务，即使在UE没有用户标识和订阅蜂窝网络的情况下也是如此。
