A water jet strengthening and polishing integrated system for blades of a blisk includes a vibration polishing unit and a water jet strengthening unit. The vibration polishing unit includes a vibration polishing bath, the vibration polishing bath is internally provided with a clamp for clamping the blisk, and vibration motors for driving the vibration polishing bath to vibrate are installed on the vibration polishing bath. Top ends of support springs are fixedly connected with the vibration polishing bath, and bottom ends of the support springs are fixedly connected with a workbench. The water jet strengthening unit includes a water jet strengthening device for carrying out water jet strengthening on the blades of the blisk and a driving mechanism for clamping the water jet strengthening device and capable of driving the water jet strengthening device to move in any direction in space.

Water jet strengthening and polishing integrated system and method for blades of blisk

A mobility management node and a method in a mobility management node for reducing signalling caused by changes of location of a radio terminal, which mobility management node is configured to be operatively comprised by a wireless communication system and to operatively manage the mobility of the radio terminal and to operatively communicate with a gateway node acting as an interface between the system and an external network. The method comprises obtaining initial position information; obtaining boundary information indicating a boundary area wherein at least one of a policy or a charging rule is to be applied for the radio terminal; obtaining current position information; determining whether the radio terminal is inside or outside the boundary area; providing mobility information when the radio terminal is outside the boundary area and not providing mobility information to the gateway node when the radio terminal is inside the boundary area.
