A device is provided for radially strengthening a polylactic acid tube, which includes a tubular mold, a rotating blade and a distal blade, wherein a rotating shaft of the rotating blade is arranged at an axial position of the tubular mold, a first end of the distal blade is movably connected to the rotating blade, and a second end of the distal blade is controlled by a control rod so as to open and close the distal blade. A strengthening method is provided, in which the device for radially strengthening a polylactic acid tube is used. The method includes loading a polylactic acid tube to be strengthened into the strengthening device, heating the strengthening device for a first preset time, rotating the rotating blade in a constant direction while opening the distal blade at a first speed such that the second end of the distal blade approaches the tubular mold, closing the distal blade and restoring the distal blade to an initial state after squeezing and scraping for a second preset time, cooling the strengthening device to room temperature, taking out a strengthened polylactic acid tube, and cutting off redundant sections. The tube strengthened by the above-mentioned strengthening device and method has a better wall thickness uniformity, more precise inner and outer diameter dimensions, with no axial orientation, and no thermal creep in a low temperature range such as body temperature, etc.

Various embodiments of the present disclosure provide a method for improving service discovery. The method comprises determining identification information of a service instance by a network node according to a profile of the service instance registered at the network node. The network node can resolve address information of the service instance based at least in part on the identification information. The method further comprises storing the address information in the profile of the service instance. According to the embodiments of the present disclosure, the maintenance of a NF profile can be improved and the service discovery and the resource configuration in a network may be optimized.

Method and apparatus for improving service discovery

Embodiments of the present disclosure provide methods, apparatus and computer program products for network function service discovery. A method implemented at a second network node in a wireless core network with service based architecture comprises: receiving a registration request for network function instance from a network function, the registration request comprising information identifying a subscriber group to which the network function instance is applicable; and storing the information in association with the network function instance. With embodiments of the disclosure, size of NF profile can be saved.
