Title:
COMMUNICATION SYSTEM, DATA PROCESSING CONTROL METHOD, SERVER, AND DATA PROCESSING CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2003/105455
Kind Code:
A1
Abstract:
The flexibility of telephone number allocation is enhanced, and the limitation on the total number of dial-in is released. On the server side, a receiving section receives request information from a portable telephone, or a requester (S01), a sub-address recognition section recognizes the sub-address included in the received request information (S02), an address conversion section converts the recognized sub-address into an IP address according to predetermined conversion correspondence information (S03), a data reading section reads content data related to the IP address generated by the conversion from a service DB (S04), and a data output section distributes and outputs the content data to the portable telephone, or the requester (S05). By using the sub-address accompanying the telephone number, the number of allocatable telephone numbers increases, and hence the limitation on the total number of dial-in is released. The flexibility of number allocation is improved because the allocation of sub-addresses can be carried out by a service provider.
