Data distribution device and transmission method
First Claim
1. A data allocation apparatus comprising:
- an acquisition section that acquires data to be sent to a communication terminal capable of simultaneously receiving data from first and second communication systems independent of each other from any system other than said first and second communication systems; and
an allocation section that allocates, of the data acquired, the data which matches the characteristic of said first communication system to said first communication system and allocates the data which matches the characteristic of said second communication system to said second communication system.

Abstract
A server (191) transmits image information consisting of basic data and complementary data to a router (100) through the Internet (192). The router (100) allocates the basic data to a BS (110) of a cellular system (193) and the complementary data to an AP (120) of a wireless LAN system (194). The BS (110) transmits the basic data to a MS (150) and the AP (120) transmits the complementary data to the MS (150). When the MS (150) is located in the area of the cellular system (193), the MS always maintains a communication channel with the BS (110) and when the MS enters the area of the wireless LAN system (194), the MS also opens a channel with the AP (120) while maintaining the channel with the BS (110). This allows the user to continue seamless communication.
