The present invention has the purpose of providing technology capable of efficiently
transmitting data when performing data communications between a mobile station
and a server apparatus. A simplified protocol TL is employed on the transport layer
instead of TCP/IP. The simplified protocol TL is used as the communication protocol
on a wireless communication path (radio-oriented interval) between an MS (Mobile
Station) 1 and a GWS (GateWay Server) 5. The simplified TL protocol
is utilized to relay data communications between the MS 1 and a CPS 8
(Content Provider Server). The response of data communications is therefore
improved by a decrease in traffic between the MS 1 and the GWS 5 and
reduction in overhead in comparison to when TCP/IP is deployed. As a result, the
user can efficiently access content provided by the CPS 8 over the Internet
via a wireless communication path. Efficient access may occur even where the wireless
communication path has low data transmission capacity in comparison to a wireline
communication path. In addition, efficient access may occur where the user is using
an MS 1 which has insufficient data processing power to deploy TCP/IP.
