Abstract

The invention discloses a navigation system comprising a mobile communication apparatus and an agent. The mobile communication apparatus comprises a first receiver, a first processor, an input device, a first communication device, and a display. The agent comprises a storage device, a second communication device, and a second processor. The mobile communication apparatus transmits current location information and destination information to the agent. The agent processes the received destination information, the received current location information, and map information transmitted from the storage device to generate a path from the current location to the destination. According to the path, the agent generates navigation information and transmits the navigation information to the mobile communication apparatus to display the navigation information.

Claims

1. A navigation system, comprising:

a mobile communication apparatus, comprising;

a first receiver for receiving GPS signals broadcasted from at least one satellite;

a first processor, electrically connected to the first receiver, for processing the received GPS signals to obtain, current location information of a current location associated with the mobile communication apparatus;

an input device, electrically connected to the first processor, for a user to input destination information of a destination to the first processor;

a first communication device, electrically connected to the first processor, for transmitting the current location information and the destination information; and

a display, electrically connected to the first processor, for displaying information outputted from the first processor; and

an agent, comprising;

a storage device for storing a map database;

a second communication device for receiving the current location information and the destination information transmitted from the mobile communication apparatus; and

a second processor, electrically connected to the second communication device and the storage device, respectively, for processing the received destination information, the received current location information, and map information transmitted from the map database to generate a path, from the current location to the destination, according to the path, wherein the second processor generates navigation information associated with a distance between the current location and a middle site on the path, and the second processor transmits the navigation information to the first communication device, and wherein, the navigation information is to be displayed on the display.

2. The navigation system of claim 1, wherein the mobile communication apparatus complies with a General Packet Radio Service (GPRS) standard.

3. The navigation system of claim 1, wherein the agent is a server installed in a base station.

4. The navigation system of claim 1, wherein the agent is a server capable of communicating with the mobile communication apparatus via a communication network and a base station.

5. The navigation system of claim 1, wherein the navigation information displayed on the display comprises an arrow picture.
