Abstract: Methods, computer program products, and apparatuses are provided for enabling a user equipment (UE) to connect to the wireless access network that support non-seamless wireless local area network (WLAN) offload (NSWO), such as using the UE's fifth generation (5G) credentials. An apparatus may include a processor and a memory storing computer program code configured to cause the apparatus to request, by the UE, a wireless connection to a network entity; receive, by the UE, from the network entity, an identity request; and in response to the identity request, cause transmission, by the UE, an identity response including a UE identifier to the network entity such that the UE is configured to establish a security context with the network entity upon successful authentication using the UE identifier.

Abstract: Embodiments of the present disclosure relate to path switch between relays and security procedures. A terminal device obtains a selection policy for selecting a RSC from a plurality of RSCs, an RSC of the plurality of RSCs being associated with an indicator for indicating whether the RSC supports a CP security procedure or an UP security procedure. Based on determining that path switching from a source relay terminal device with a source RSC is triggered, the terminal device selects a target RSC based on the selection policy, a source indicator being associated with the source RSC, and a plurality of indicators being associated with the plurality of RSCs. The terminal device selects, for the path switching, a target relay terminal device based on the target RSC. As such, the service continuity after path switching between relays can be improved and delay or disruptions to the service can be avoided.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus receive a downlink, DL, non-access stratum, NAS, transport message comprising a plurality of payload containers. The plurality of payload containers comprise a user equipment parameters update, UPU, transparent container and one or more non-UPU payload containers. The UPU transparent container comprises a re-registration, REG, flag having a true value indicating that re-registration of the apparatus is requested. The apparatus sends the plurality of payload containers to respective upper layers for processing. The apparatus triggers the re-registration following detection of completion of the one or more respective processes associated with the one or more non-UPU payload containers.

Abstract: Techniques are disclosed for managing reauthentication and revocation in a communication network environment. In one example, a method comprises receiving, at a first network entity (e.g., an NSWOF), a request from a second network entity (e.g., a UDM) of a communication network to which user equipment is subscribed (e.g., HN), wherein the received request is for a reauthentication or a revocation of the user equipment in accordance with wireless local area network access. The first network entity identifies the user equipment based on information about the user equipment (e.g., UE context) previously stored by the first network entity. The first network entity sends at least a portion of the received request toward the user equipment, and then continues to participate in the reauthorization or revocation based on the request.

Abstract: Apparatus and method for counter measures for attacking messages are provided. Solution comprises communicating (500) with another apparatus utilising sidelink transmissions, monitoring (502) for an attacking sidelink message based on the content or timing of received messages and entering (504) a defensive mode to mitigate the attack when one or more received messages has been detected as attacking sidelink messages.

Abstract: Example embodiments of the present disclosure relate to UP traffic handling for emergency case. A first terminal device determines that UP traffic is to be communicated between the first terminal device and a second terminal device without confidentiality protection. The first terminal device determines that the UP traffic is to be communicated between the first terminal device and the second terminal device without integrity protection or with a partial integrity protection. The first terminal device transmits, to the second terminal device, a message indicating that the UP traffic is to be communicated without the confidentiality protection or the integrity protection, or without the confidentiality protection and with the partial integrity protection. In turn, the first terminal device communicates the UP traffic between the first terminal device and the second terminal device without the confidentiality protection or the integrity protection, or without the confidentiality protection and with the partial integrity protection.
