Description
Technical field
The present invention is applicable to mobile Internet information service technical field, particularly a kind of system and method that utilizes WLAN to carry out the local information service.
Background technology
Information service system is the system that the direct user oriented that is widely used in places such as enterprise, government, market, traffic terminal provides information service, is the important means that ensures information opened.In order to realize information transmission towards the public, people have adopted leaflet, picture poster, electronic bill-board, unit advertisement machine or the like mode significantly.But the propaganda pattern that these are traditional, exist with high costs, carrier is single, amount of information is limited, can not manage concentratedly, content is changed defectives such as difficulty.And in these patterns, the user is in passive status, can not obtain information on one's own initiative, causes information service efficient and user satisfaction all lower.
Especially follow fast development economic and science and technology, how the multimedia display content more and more nothing to be surprised at that becomes improves the quality of information service, the speed of accelerating information service causes the concern that People more and more is many.It is " a kind of multi-media information distribution method based on wireless network " that CN101291277A proposes that this research on the one hand has the Chinese patent publication number; Patent publication No. is " based on unit personnel management, advertising message issue and the acquisition system of Bluetooth communication " that CN201207648Y proposes; These two patents have all made full use of a kind of radio network technique, have realized the efficient issue of information.Though these two patents have all overcome the deficiency of conventional information release model to a certain extent, and its deficiency is respectively arranged." GPRS, the CDMA " that mentions among the patent CN101291277A and " SMS " though etc. mode area coverage under the support of operator wide; (the highest theoretical velocity of CDMA is 153.6Kbps but speed is lower; The highest theoretical speed of GPRS is 171.2kbps); And need the cooperation of operator, use cost is than higher, and the user needs payment data traffic fee etc.The Bluetooth technology that patent CN201207648Y mentions, speed lower (the highest theoretical speed of bluetooth is 720kbps) and area coverage less (being generally the order of magnitude of 10m).
WLAN (WLAN) technology is a kind of high-speed radio IP network communication technology that grows up for 20 end of the centurys.WLAN has two kinds of networking modes: reciprocity networking and basic schema networking.The equity networking does not need AP, communicates with one another between all wireless terminals (STA); The basic schema networking then needs AP (WAP), and all signals that wireless terminal sends and data all will send to AP earlier, are transmitted to the purpose terminal by AP then.Compare with other wireless networks, the advantage of WLAN is speed and scope, and its flank speed can reach 300Mbps (based on the wlan network of 802.11n agreement); Single AP can cover the 100m order of magnitude, can cover bigger area through the networking between AP.
At present, along with the price of AP in the WLAN technology reduces day by day, the hot zones of WLAN has been set up in increasing place, builds that the wlan network cost is lower, coverage is wider, easy to operate.On the other hand, the terminal with WLAN function is also more and more, and except traditional LapTop, present increasing intelligent terminal (mobile phone/flat board etc.) is also supported WLAN.
For this reason, how overcoming the deficiency of tradition and existing other local information service systems, how to utilize the WLAN technology of popularizing day by day to realize the high-efficiency information service, is the problem that need solve.
Summary of the invention
The object of the present invention is to provide a kind of system and method that utilizes WLAN to carry out the local information service; To make things convenient for intelligent terminal user gratis to obtain specific products and information on services; The validity that raising information is propagated enlarges the information owner and utilizes information the user to be carried out the channel of information service.
The objective of the invention is to realize through following technical scheme:
A kind of system that utilizes WLAN to carry out the local information service is characterized in that this system comprises:

Access point AP receives the request of information service, obtains information from information server, and gives intelligent terminal with said distribution of information;
Information server is used for maintenance and management to want information releasing.
Said intelligent terminal, said access point AP have identical SSID.
Said intelligent terminal can communicate with said access point AP through said wireless local area network communications module.
Said intelligent terminal can trigger the request of intelligent terminal transmission information service and arrive said access point AP, and the information of AP distribution is presented to the intelligent terminal user through the local information service software.
A kind of WLAN that utilizes carries out the local information service method, it is characterized in that this method comprises the steps:
Step 2 after this access point AP receives the request of information service, is obtained information service from information server;
Step 3, this access point AP returns to this intelligent terminal with the information service of obtaining;
Step 4, this intelligent terminal receives information service, and this information is presented to the intelligent terminal user.
As stated before the step 1, said access point AP be said intelligent terminal can detected all access point AP in the AP that from all AP tabulations, initiatively selects of the strongest AP of signal or intelligent terminal user.
The invention provides a kind of system and method that utilizes WLAN to carry out the local information service, have following advantage and characteristics:
1) the intelligent terminal user utilizes the information service that system and method provided by the invention can obtain convenient, fast, effectively to be needed; Saved and opened web browser; Key in correspondent keyword and search for, a series of loaded down with trivial details steps consuming time again such as information that searching needs in the numerous clauses and subclauses that eject then.
2) system and method provided by the invention is based on client-server architecture; Promptly carry out information service by intelligent terminal active request AP; The request of AP and information server response intelligent terminal sends to the user with information then, can avoid the situation of information harassing and wrecking to take place so effectively.
3) the intelligent terminal user adopts native system and method to obtain information, through the network online of Mobile Network Operator (China Mobile/China Telecom/CHINAUNICOM etc.), has not saved traffic fee.
4) the intelligent terminal user adopts native system and method to obtain information service, and faster through WLAN speed, coverage is bigger, operates easier.
