    摘要: A mobile communication system including a plurality of base stations arranged in a communication area, each emitting a radio wave inherent thereto and a mobile station moving in the communication area and communicating with respective base stations via the transmitted radio waves. There is previously stored a location correlation data group including correlation data representing correlation situations of a plurality of arriving radio waves produced by the transmitted radio waves at respective ones of a plurality of sampling locations within the communication area, the location correlation data corresponding to respective locations. Upon reception of radio waves at a current location of the mobile station, current correlation data is calculated representing correlation situations among received arriving radio waves for the respective mobile station. The location correlation data in the location correlation data group is compared with the current correlation data, and the current position of the mobile stations is determined in accordance with a result of the comparison, generating the determined current position data.

    摘要: In an online marketplace environment, a seller of items can provide information relating to items for sale on one or more online sales channels to a connection provider. In one implementation, a method describes receiving a product data file (PDF) from a seller, in which the product data file includes information relating to one or more items for sale by the seller. The method also includes facilitating a sale of the one or more items through one or more online sales channels, in which the product data file further includes one or more data fields for enhanced selling features. The enhanced selling features include selling features in addition to baseline features. The baseline features include providing online listing capabilities for the one or more items being sold.
