Fig. 1. The scheme of information transfer via Internet-server.

Each cell phone exchanges data with Internet-server using corresponding service of Internet access provided by mobile operator. Communication between server and cell phone goes by HTTP-protocol. This provides efficiency of the mechanism of exchange between server and cell phone regardless of both cell phone model and standard of operator’s mobile communication. To low the price of information transfer, cell phone connects to server only at moment when transferring or receiving information. Information is transferred in compact coded form. You can increase the rate of connecting with server to reduce time of getting rival’s response move or vice versa - you can reduce the rate of connecting driver to reduce the volume of information transferred and thus cut down charges for using Internet.
