Abstract

A data transfer system includes a data conversion storage server (3) that generates data (MD1) having a size smaller than a size of data (MD0) received from a delivery server (5) by performing a specific process on the data (MD0). A base station control unit (2) is provided with a data transferring portion that transfers one of the data (MD0 and MD1) selectively to a mobile phone terminal (1), and an approaching mobile communication equipment sensing portion that senses a mobile phone terminal (1) that is receiving the data (MD0) and is approaching an HSDPA supporting wireless base station (4). Then, the data transferring portion stops sending the data (MD0) to the mobile phone terminal (1) sensed by the approaching mobile communication equipment sensing portion, and instead it starts transferring data (MD2) related to a part of the first data to be transferred.

Claims8

Dependent claims

A data transfer system comprising:

a processor to control the data transfer system in accordance with processing including
receiving beforehand designation of one of first data processing, second data processing, and third data processing,
transferring first data to mobile communication equipment, the first data being transmitted from a server,
sensing that the mobile communication equipment is approaching a second wireless base station from a first wireless base station when the mobile communication equipment is receiving the first data, and
after it is sensed that the mobile communication equipment is approaching the second wireless base station from the first wireless base station, stopping transferring the first data to the mobile communication equipment, and instead, in accordance with the designation, performing any one of the following (a) through (c):
(a) if the first data processing is designated beforehand generating second data having a higher compression ratio than a compression ratio of the first data by applying a specific process on a portion of the first data which has not been transferred yet, and transferring the second data to the mobile communication equipment;
(b) if the second data processing is designated beforehand, generating third data having a sound component of the first data by applying a process of removing a picture component from the portion and transferring the third data to the mobile communication equipment;
and
(c)if the third data processing is designated beforehand, storing the first data as fourth data.

(d) if the first data processing is designated beforehand, stopping transferring the second data but, instead, transferring the first data corresponding to a portion of the second data which has not been transferred yet;
(e) if the second data processing is designated beforehand, stopping transferring the third data but, instead, transferring the first data corresponding to a portion of the third data which has not been transferred yet;
and
(f) if the third data processing is designated beforehand, transferring the fourth data to the mobile communication equipment.
