How to check the status of wireless data service for the called mobile terminal {METHOD FOR CONFIRMING THE RECEPTION STATE OF WIRELESS DATA SERVICE FOR A DESTINATION MOBILE TERMINATION}

The present invention relates to a wireless data service for a mobile terminal, and more particularly, to a method for confirming a wireless data service availability state of a called mobile terminal at a calling party so as to provide a wireless data service without loss of data.

In general, the wireless data service is a service implemented to use services such as PC communication, the Internet, and file transmission and reception, which were supported in a wired environment, through a mobile terminal. In order to use such a wireless data service, the mobile terminal must remain connected to the information terminal by cable or wirelessly. This is because, when using a wireless data service, the mobile terminal only plays the role of a modem. Therefore, when wireless data service is performed between mobile terminals, data to be actually transmitted is held by an information terminal connected to the calling mobile terminal, and wireless data received through the called mobile terminal is connected to the called mobile terminal. It will be downloaded from the information terminal. The information terminal described above is composed of equipment such as a personal digital assistant (PDA), a personal computer, and the like.

However, since the mobile terminal cannot always be connected to the information terminal due to the characteristics of the mobile terminal, when using a wireless data service, the calling party needs to check whether the called mobile terminal is connected to the information terminal. This is because, when the wireless data is transmitted without the confirmation process, if the called mobile terminal is not connected to the information terminal, normal reception processing is not performed and data is lost.

Therefore, in order to prevent loss of data during the wireless data service, there is no method other than requesting preparation for the wireless data service by a voice call with the called mobile terminal before starting the wireless data service. The calling party was not only cumbersome to check the incoming readiness for the wireless data service, but also suffered financial losses due to ancillary voice calls. This problem is more pronounced when the number of destination mobile terminals for wireless data service is large. That is, in the case where the number of the called-party mobile terminals which wants to transmit data by using the wireless data service at the calling party is N, the calling party should check the state of the wireless data service available through N voice calls.
