Abstract: A solution for security negotiation during handover of a user equipment (UE) between different radio access technologies is provided. In the solution, the UE receives non-access stratum (NAS) security information and access stratum (AS) security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a Long Term Evolution (LTE) system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a Universal Terrestrial Radio Access Network (UTRAN), to the LTE system.

Abstract: A tool bit for an ultrasonic osteotome includes a bit body, an arbor fixed to the bit body, and a flat end portion fixed to the arbor. A toothed edge extends linearly along a length direction of an end portion of the tool bit, and recesses are distributed evenly on the toothed edge to form teeth spaced apart from each other. The toothed edge extends linearly along a length direction, and the cutting edges of teeth are distributed linearly, e.g., instead of having a sharp structure, thus will not scrape and hurt other tissues during cutting. Since the thickness of the cutting edge is the same as that of the back edge, when cutting bone tissues, the incision is wide, thus the end portion is not easy to be clamped by bone tissue, which effectively prevents the end portion from breaking and reduces occurrence chances of surgery accidents.
