Description
Technical field
The present invention relates to navigation Service, especially relate to a kind of terminal, system and method that navigation Service is provided.
Background technology
Basic mobile communication system is made up of mobile communication terminal, base station, base station controller and mobile station.Wherein, mobile communication terminal is meant as digital Cellular Networks (DCN:Digital CellularNetwork), the mobile communication terminal (Mobile Terminal) that personal portable communication service (PCS:Personal communication Service) is the same, the signal format between mobile communication terminal and the base station controller is changed in the base station, make its suitable wireless connections and wired connection, base station controller is the coupling arrangement between the application person in the function of each factor classification of base station and the zone, and carry out base station applies and manage, the service state management of the hardware and software in the base station, resources allocation and formation to the call communication amount, the information search that base station applies is relevant, base station applies, the function for monitoring of supervision and fixing lower device of being correlated with etc.And, the telex network tie point between the mobile station of mobile station formation base stations control management and mobile communications network and regular phone net or same mobile communication system.
Along with development of wireless communication devices, the cost of use of mobile communication terminal is cheaper, and speech quality also improves in succession, even vehicle under steam also can carry out the conversation of high words matter, thereby the user who uses suddenly increases.
And the Internet is the network that size computer network in the whole world is formed by connecting, so merely only two computing machines are connected and receive and dispatch mutual data, also can be regarded as and has constituted the Internet.
That is, computer network (Computer Network) is meant the connection net self that connects for the mutual exchange message of each computing machine.Under the state that computer network constitutes, be connected between the computing machine of the Internet exchange message and just cry compunication (computer communication).This computer network, little forms in office, and the network of office is connected with the building or than its larger network, and be included in larger network.Like this, the scale of network is connected to form LAN (Local Area Network) (LAN:Local Area Network) with provincialism, and LAN and LAN are interconnected to form network interconnection (internetworking) and form larger Metropolitan Area Network (MAN) (MAN:Metropolitan AreaNetwork).This MAN gets together and forms large-scale network WAN (Wide Area Network).WAN is the network that is on a grand scale that almost constitutes the maincenter of a country.
Local each self-forming of each of the world and the network of growing up surmount the border finally becomes the catenet that has connected between country and the country.As a result,, can connect, also can pass through the artificial satellite wireless connections, that is, global link be become a network with several different methods by submarine optical fiber cable to today.What the either large or small computer network in this world was got together just is the Internet (internet).
Above-mentioned terminal just merely is used in voice communication at the beginning, but, also is used for data communication in recent years, and mobile communication service business person is providing hundreds of contents such as news, banking, ecommerce with the wireless Internet mobile phone recently; But also utilize mobile phone to carry out that AM or FM radio reception broadcasting is listened to or downloading the MP3 music with audio file formats (file extent mp3) on the Internet and being stored in the mobile phone, can play appreciation at any time when needed; Mobile phone comes out to have as above multiple function.
Recently, navigation Service attracts tremendous attention, and navigation Service is by positional information being offered the automated induction systems of terminal or automobile, and this automated induction systems carries out correct guiding with terminal or automobile to its destination according to the positional information of receiving.For example, the automobile that navigational system has been installed receives positional information from artificial satellite or geomagnetic sensor or road traffic guiding center and is directed, and is presented on the display with the position of the map of current driving environment, automobile and apart from information such as destination shortest paths.
The navigation feature of existing personal portable terminal is to utilize approach (source) such as CD-ROM to be installed in back on the automobile to guide the mode in needed path, the perhaps mode of informing the user from navigation server reception shortest path under the state that terminal continues with the Internet is connected to the user.
Fig. 1 is the synoptic diagram of common navigational system.
With reference to Fig. 1, as data source (datasource), and this navigational system is installed on the automobile common navigational system with medium such as CD-ROM (media), by the departure place of retrieval user input, place of arrival also extracts shortest path from data source, provides it to the user.
But except that personal mobile communication device, the user needs to buy in addition the new navigational system that is installed on the automobile, and can't receive the needed information of navigation except that the information that reads from data source at all.Thereby under situations such as information change such as map, existing needs to receive again the also inconvenience in installation data source.
In addition, except that the guidance path of having imported, can not provide the traffic information relevant, thereby have the drawback that is difficult to provide actual bee-line with the current driving path.
Fig. 2 is the synoptic diagram that utilizes the navigational system of existing mobile communication terminal.
With reference to Fig. 2, the navigational system based on mobile communication terminal in the past comprises: support to utilize the connection of WAP (Wireless Application Protocol) mode or wireless HTTP (Hypertext TransferProtocol) and the mobile communication terminal 1 of the GPS built-in chip type that wireless data packet connects; Mobile communication terminal 1 carries out the wireless Internet 2 of wireless connections therewith; By the navigation server 4 of navigation Service is provided because of special (data) net 3.
If the mobile communication terminal 1 of built-in above-mentioned GPS chip is attempted being connected the line correlation setting of going forward side by side with navigation server 4 for providing of navigation Service is provided by wireless Internet 2, after the navigational system based on mobile communication terminal of structure is connected to the Internet 3 so as mentioned above, the cartographic information that the data that transmit from the GPS chip and navigation server 4 are provided makes up, and provides service to mobile communication terminal 1 user.
In the aforesaid navigational system, the user can utilize the portable mobile communication instrument of the built-in GPS that has used to receive navigation Service, still, and in order to receive this service, communication instrument need keep the state that continues to be connected with the Internet, thereby exists the user need pay the drawback of a lot of expenses.
