    Abstract: Embodiments of the present disclosure relate to security communication in ProSe U2N relay. According to one aspect of the present disclosure, remote UE and relay UE receive a configuration comprising at least a set of indicators of a CP based security procedure or a UP based security procedure for a set of relay services. Based on an indicator for a relay service in the set of indicators, the remote UE and relay UE performs one of the CP based security procedure or the UP based security procedure for a communication between the remote UE and the relay UE for the relay service. In this way, remote UE and remote UE may correctly trigger a security procedure for U2N relay communication.

    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: Systems, methods, apparatuses, and computer program products for a method of mobility between distributed units with a local control plane are provided. For example, a method can include detecting, at a target distributed unit, a handover based on an indication from a source distributed unit after a handover command has been sent to a user equipment to hand over from the source distributed unit to the target distributed unit. The method can also include sending, from the target distributed unit to a central unit user plane, a data transmission resume notification, to trigger to the central unit user plane to resume downlink data transmission toward the target distributed unit. The downlink data transmission was previously suspended by instructions from a source distributed unit to the central unit user plane when the handover was initiated from the source distributed unit to the target distributed unit.

    Abstract: Techniques are disclosed for user equipment authentication in a shared access network environment. In one example, a method comprises establishing, via a first access management entity in a first communication network that has a radio access network associated therewith, a secure connection with a second access management entity in a second communication network to which user equipment subscribes, and facilitating, via the first access management entity, authentication of the user equipment in conjunction with the second access management entity over the secure connection to enable the user equipment to utilize the radio access network of the first communication network to access the second communication network.

    Abstract: Systems, methods, and software of performing an Authentication and Key Management for Applications (AKMA) authentication service. An AKMA authentication proxy resides between User Equipment (UE) and a plurality of Application Functions (AFs). The AKMA authentication proxy receive an application session establishment request message from the UE requesting an application session with a first application function, sends a key request message toward an AKMA anchor function (AAnF) requesting AKMA application keys for a plurality of application functions, receives a key response message sent from the AAnF that includes the AKMA application keys, identifies a first AKMA application key for the first application function from the AKMA application keys derived by the AAnF, and forwards the application session establishment request message to the first application function with the first AKMA application key.
