<p><P>PROBLEM TO BE SOLVED: To obtain a data communication method by which mobile IP communication can be efficiently performed with a simple configuration. <P>SOLUTION: This method is a data communication method in a mobile IP network system having an AP2b connected on a mobile IP network; a mobile terminal 1; terminals 3Y, 3Z for performing data communication with the mobile terminal 1; and a terminal 3W for receiving data to be transmitted by the terminals 3Y, 3Z to the mobile terminal 1 from the terminals 3Y, 3Z, and storing the received data. In this method, if the processing capability of data communication to be performed by the mobile terminal 1 with the terminals 3Y, 3Z deteriorates; the mobile terminal 1 selects predetermined data being presently communicated by the terminal 1 with the terminals 3Y, 3Z according to the deterioration in processing capability of the mobile terminal 1, the selected data from an initial part onward are transmitted from the terminals 3Y, 3Z to the terminal 3W, and the data received by the terminal 3W from the terminals 3Y, 3Z are transferred to the mobile terminal 1 in response to a request from the mobile terminal 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
