Abstract

PURPOSE: A contents download reservation service method is provided to enable a user to download contents by using data channels remaining at a wireless traffic time band by offering a contents download reservation service. CONSTITUTION: A mobile terminal accesses a contents providing server via a wireless network, a gateway and the internet, and the contents providing server displays a contents download reservation menu on a WAP(Wireless Application Protocol) browser(S201). The contents providing server reserves the contents download according to sequential menu selections on the mobile terminal, specially stores an MIN(Mobile Identification Number) and data on the reserved contents at a database and finishes reserving the contents download(S202, S203). The contents providing server periodically checks a wireless traffic state, and determines whether a wireless traffic is lower(S204). The contents providing server continues to check the wireless traffic state if the wireless traffic is not lower(S205). The contents providing server extracts the MIN of the mobile terminal from the database if the wireless traffic is lower(S206), requests a call connection to the wireless network via the internet and the gateway, and then connects to the mobile terminal over the wireless network(S207). The contents server transmits WML(Wireless Markup Language) script type data on the store contents, for example, a URL, a contents name, a version and a mux option, to the mobile terminal(S208). The mobile terminal changes an MO parameter among the WML script parameters with the mux option, is set to an allocated channel, and drives a VOD(Video On Demand) player(S209, S210). Then the VOD player downloads the reserved contents via the allocated channel(S211) and releases the allocated channel(S212).
