Data transmitting and receiving method between a mobile terminal and an information center in a navigation system
First Claim
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 the received path guiding data in the mobile terminal when the connection is disconnected during reception of the path guiding data corresponding to destination information and current location information, wherein the mobile terminal automatically checks when the connection with the information center is disconnected before reception of the path guiding data is completed and stores the path guiding data received prior to disconnection in an internal memory;
(b) transmitting automatically via the mobile terminal a reconnection request message and a message including path guiding data corresponding to the stored information on the received path guiding data to the information center, prior to reconnection; and
(c) receiving at the mobile terminal the rest of the path guiding data transmitted from the information center upon reconnection and in response to the reconnection request message and in accordance with the message including the path guiding data.
