Abstract

A data transmitting and receiving method between a mobile terminal and an information center in a navigation system is disclosed. The present invention is characterized in that if lower items of a destination are not received from the information center in the middle of receiving destination setting items to set the destination after the mobile terminal transmits a destination setting request message to the information center, the mobile terminal sends a reconnection request message and stored destination setting data.

Claims

1. A method for transmitting and receiving path guiding data of a mobile terminal in a navigation system, which comprises an information center for providing navigation information and the mobile terminal connected with the information center via a wireless network, the method comprising the steps of:

(a) storing information on received data if the connection is disconnected during reception of the path guiding data;

(b) transmitting a reconnection request message and a message corresponding to size of the received data to the information center; and

(c) receiving the rest of the path guiding data transmitted from the information center.

2. The method according to claim 1, the step (a) comprising the steps of:

transmitting the last set destination information and current location information to the information center;

receiving the destination information and the path guiding data corresponding to the current location information from the information center; and

checking if the connection is disconnected before reception of the path guiding data is completed and storing the path guiding data received prior to disconnection to an internal memory.
