Abstract: Aspects relate to security mechanisms for protecting transmissions in wireless communication systems. Various examples provide and enable techniques for protecting transmissions of user equipment (UE) radio capability information. A UE may transmit a hash of its UE radio capability information to a network. The network can then utilize the hash to verify the integrity of the UE's radio capability information upon acquiring the full UE radio capability information during a UE Capability Enquiry procedure. Other aspects, embodiments, and features are also claimed and described.

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: The present disclosure provides techniques that may be applied, for example, in a multi-slice network for maintaining privacy when attempting to access the network. An exemplary method generally includes transmitting a registration request message to a serving network to register with the serving network; receiving a first confirmation message indicating a secure connection with the serving network has been established; transmitting, after receiving the first confirmation message, a secure message to the serving network comprising an indication of at least one configured network slice that the UE wants to communicate over, wherein the at least one configured network slice is associated with a privacy flag that is set; and receiving a second confirmation message from the serving network indicating that the UE is permitted to communicate over the at least one configured network slice.

Abstract: In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and/or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.

Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

Abstract: A user device having a security context with a first network based on a first key may establish a security context with a second network. In a method, the user device may generate a key identifier based on the first key and a network identifier of the second network. The user device may forward the key identifier to the second network for forwarding to the first network by the second network to enable the first network to identify the first key at the first network. The user device may receive a key count from the second network. The key count may be associated with a second key forwarded to the second network from the first network. The user device may generate the second key based on the first key and the received key count thereby establishing a security context between the second network and the user device.

Abstract: Aspects of the disclosure relate to configuration of the Access Stratum (AS) security in communication networks. The AS security may be defined by security configuration information selected for a protocol data unit (PDU) session established for a user equipment (UE). The security configuration information may be selected by a network node within a core network based on one or more of the PDU session, device type of the UE, or Quality of Service (QoS) flow within the PDU session. The security configuration information may be provided to a radio access network (RAN) serving the UE for selection of an AS security configuration that is specific to the PDU session.

Abstract: The present disclosure provides techniques that may be applied, for example, for providing network policy information in a secure manner. In some cases, a UE may receive a first message for establishing a secure connection with a network, wherein the first message comprises network policy information, generate a first key based in part on the network policy information, and use the first key to verify the network policy information.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for discovering a controller function for wireless backhaul using cellular radio access technology (RAT) such as communications systems operating according to new radio (NR) technologies. For example, such a method may include connecting to a parent relay that provides connectivity to a controller function (CF) of a network, receiving, from the parent relay, information regarding at least one of: the CF or a radio access network (RAN) area covered by the CF, obtaining an identifier of the CF using the information, and connecting to the CF using the identifier.
