Abstract: The present invention provides a system and method for reducing loads of a mobility management entity in core networks. An object sending a connection-request message asking for network access to a base station through a wireless network; the base station receiving the connection-request message and sending it to core networks through a network; a mobility management entity (MME) in the core network receive the connection-request message. If the core network is busy and refuses to interconnect with the object, MME calculating according to a management rule a back-off time; MME transmitting a response message including the back-off time to the object through the base station, and the object sending out a connection-request message again after the back-off time has elapsed according to the response message.

Abstract: A transmission mechanism for weft bars of knitting machine comprises pairs of connecting rods each pair having one end coupled to the weft bar; connection members having one ends coupled to the other ends of the connecting rods; universal rods having one ends pivotably coupled to the other ends of the connection members; upper engagement blocks having upper sides pivotably coupled to the other ends of the universal rods; lower engagement blocks having top teeth on either end; belts each having parallel teeth on the inner surface, each belt being movable between the upper and the lower engagement blocks with the teeth thereof meshed with the top teeth of the lower engagement block; two transverse rods inserted through the lower engagement block for connecting the lower engagement block and the knitting machine together; sensors each secured on the upper engagement block for controlling the motions of the upper and the lower engagement blocks; pairs of idler gears each pair provided on two sides of the belt; pa

Abstract: A transmission mechanism of a needle platform of a knitting machine is provided with a three-way master transmission shaft and two three-way slave transmission shafts which are provided with an eccentric actuation seat which is connected with the needle platform by a connection rod in conjunction with a radial bearing. A transmission mechanism of a weft seat of the knitting machine is provided with a transmission wheel, a fastening seat, an eccentric shaft, and actuation crank for bringing about an eccentric motion to convert the transmission power into a linear motion.
