Abstract: Methods and apparatuses for detection of session status are disclosed. According to an embodiment, a user plane (UP) of a base station receives, from a control plane (CP) of the base station, a request for releasing at least one bearer for a terminal device. The request comprises time information usable for deriving a first time at which the at least one bearer was detected by the CP of the base station as needing to be released. The UP of the base station determines a session status of the at least one bearer based on the time information and sends, to the CP of the base station, a response to the request. The response comprises the determined session status of the at least one bearer.

Abstract: Airbag cushions and related assemblies comprising improved internal tethers for reshaping deployment. In some embodiments, the assembly may comprise an inflatable cushion and an internal tether comprising an elongated axis positioned within the inflatable cushion, wherein the internal tether comprises a first concave portion attached to a first internal surface of the inflatable cushion and a second concave portion attached to a second internal surface of the inflatable cushion.
