Abstract: Embodiments of the present disclosure relates to a method, and an apparatus for dynamic QoS characteristics query in mobile network. The method performed by a first network node in a communication network may comprise: receiving a request about QoS information for a terminal device. The method may further comprise: determining the QoS information for the terminal device, based at least on a location of the terminal device and/or a network status. The method may further comprise: transmitting a response including the determined QoS information. According embodiments of the present disclosure, it is possible for the UE or other server node to obtain information about currently available QoS. It will take full advantage of network resources and UE could avoid meaningless retry operations.

Abstract: In a first embodiment, implantable drainage devices with a curvilinear portion are provided, such as stents or drainage catheters formed as a tubular member having a curvilinear portion comprising one or more pairs of adjacent bends curved in opposite directions. The drainage devices house a drainage lumen that may extend through the curvilinear portion, which may be dimensioned to retain the drainage device within a body vessel and provide a desired fluid conductance through a tortuous portion of the drainage lumen within the curvilinear portion. The curvilinear portion may include two or more planar bends facing in opposite directions.
