  • Patent number: 8233917
    Abstract: A method of providing locations services of a mobile station in a worldwide interoperability for microwave access (WiMAX) network including an access service network (ASN) is provided. For executing a paging and location update (PLU), a serving base station transmits a scanning interval allocation response message (MOB-SCN-RSP) defined in the WiMAX wireless standard to a target mobile station, which transmits a scanning result report message (MOB-SCN-REP) defined in the standard to the serving base station in response to the MOB-SCN-RSP. The serving base station generates a location measurement result based on the MOB-SCN-REP and transmits to the ASN gateway. The ASN gateway forms a location response based on the location measurement result and transmits the location response to an LCS server. The LCS server creates a location service response of the target mobile station based on the location response and transmits the location service response to the LCS client.

  • Patent number: 6264759
    Abstract: A method for manufacturing wire rods and steel wire for use in making bead wires, wire ropes and springs is disclosed. That is, high drawability wire rods and a manufacturing method therefor are disclosed, in which the wire drawing is possible without carrying out patenting (an intermediate heat treatment). The high drawability wire rods for making high strength steel wire includes a steel containing, in wt %, 0.4-0.65% of C, 0.1-1.0% of Si, 0.1-1.0% of Mn, 0.3% or less of Cr, 100 ppm or less of B, Fe and other unavoidable impurities. The steel further contains 0.02% or less of one or more elements selected from a group consisting of Ti, Nb and V. The steel has a degenerated pearlite structure with pro-eutectoid ferrite of 10% or less, the remaining part being a discontinuously formed cementite. A billet having the above composition is hot-rolled, and is cooled at a cooling rate of 10-30° C./sec.
