Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a control message that includes an identification of a set of protection levels corresponding to different degrees of physical layer security for securing communications between the UE and the base station. The base station may transmit, to the UE, an indication of an identified protection level of the set of protection levels to be used by the UE for securing the communications between the UE and the base station. The UE may communicate with the base station in accordance with the identified protection level.

Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

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.

A method, performed by a user equipment (UE), for protecting data includes: transmitting an attach request message including at least one security protection parameter regarding a UE capability to support a security protection for a user plane, to a mobility management entity (MME) via a base station; and in case that a security policy is determined at a policy charging function (PCF) based on the attach request message and information of the security policy is received at the MME, receiving an attach accept message including at least one security protection parameter regarding a network capability for the security policy related with an evolved packet system (EPS) bearer, from the MME via the base station.

A modular surgical instrument system that comprises modular components and a control circuit electrically couplable to the modular components. The modular components comprise a shaft and a handle assembly. The handle assembly comprises a disposable outer housing. The disposable outer housing is movable between an open configuration and a closed configuration. The handle assembly further comprises a control inner core receivable inside the disposable outer housing in the open configuration. The disposable outer housing is configured to isolate the control inner core in the closed configuration. The modular components further comprise a loading unit releasably couplable to the shaft and a staple cartridge releasably couplable to an end effector. The loading unit comprises the end effector. The control circuit is configured to generate an interrogation signal, detect a response signal, determine a modular configuration of the modular surgical instrument system, and assess authenticity of the modular configuration.

An example operation includes one or more of receiving a request into a transport network comprising at least one transport for a proposed use of personal data associated with the at least one transport prior to the at least one transport entering an area; receiving into the transport network a deletion time of the personal data, prior to the at least one transport entering the area; providing, from the transport network an acknowledgement of the deletion time; and providing, from the transport network, the personal data when the at least one transport is in the area based on the received acknowledgement. This enables an occupant of a transport to share personal data relating to the transport with confidence that the data will be deleted by an agreed time.
