PURPOSE: A method for providing a data receiving service to a mobile terminal in a mobile telecommunication system is provided to establish a termination data call without a data termination request by a user. CONSTITUTION: A data service server provides an origination request message to an MSC through an IWFs(Interworking Functions) together with its own telephone number using the telephone number of a mobile terminal(S1). Based on the telephone number of the data service server, the MSC judges that the origination message is for a data termination request. Then the MSC asks an HLR whether the mobile terminal is a data termination service subscriber terminal(S2,S3). In response to the question of the MSC, the HLR confirms a subscriber profile stored under the telephone number of the mobile terminal, and provides a confirmed result to the MSC. In case that the mobile terminal is a data termination service subscriber terminal, the MSC provides a data termination service message to the mobile terminal through a page channel and an access channel(S4). In response to the data termination service message, the mobile terminal provides a data termination call setup request message to the MSC through the data service server number(S6). Based on the message provided from the mobile terminal, the MSC establishes a data transmit-receive channel to the data service server and the mobile terminal(S7). |
